With the continuous development of China's glass bead technology, perfect use of glass beads in more fields are presented to people. Glass beads are the most common adornment accessories in the advanced society, which are widely used in the fields of clothing, shoes, hats, handicrafts and other decorative fields. Today, China also produces reflective glass beads for road.

Reflective glass beads are also divided into two categories: one is ordinary glass beads, which are mainly used for road coating, the other is high refractive index glass beads, which are mainly used for reflective weaving, which are widely used in the clothes of traffic police and highway signs, so what are the specific manufacturing processes of glass beads?

Specific manufacturing processes of glass beads

The first step is to make all kinds of ball-shaped roughcasts by using advanced technology;

The second step is to put the roughcasts into a grinding disc with the same size, add oil and coarse abrasive to carry out rough grinding;

The third step is that when the primary grinding is completed, the oil and coarse abrasive adhering to the surface of the ball shall be cleaned;

The fourth step is to put the rough ground roughcasts into the fine grinding machine, add oil and fine abrasive for fine grinding;

The fifth step is to carry on polishing. The polishing process is similar to that of coarse grinding and fine grinding.

In the series of glass beads, the road reflective glass beads can be said to be the most widely used. Road reflective glass beads are mainly made of borosilicate, light and good chemical preparation. The main feature is the strong internal structure stability. If the road reflective glass beads are processed specially, the road marking reflective glass beads can have the effect of lipophilic and hydrophobic.

In addition,  road reflective glass beads are also widely used in artificial agate by consumers. Marble and other composite materials, so that it not only can play a role in reducing weight but also can play the effect of sound insulation so that the products will have cracking and processing.

The application of road reflective glass beads can be divided into three categories:

1. The road light-emitting glass beads are used for surface spreading in normal temperature and hot-melt standard construction, which plays a role of timely reflection.

2. Road reflective glass beads are often used as premixed materials, which can ensure long-term reflection of marking line within the life span.

3. It is also often used to spray glass beads on the surface of the normal temperature solvent coating line.

The manufacturer of road marking glass beads will be arranged for you: the reflection of marking is from the glass beads in the coating in advance and the glass beads spread on the coating surface. If the roundness index and refractive index of glass beads are high and the particle size distribution is reasonable, the reflective effect of markings will be good.

The particle size of glass beads is matched in a certain proportion to ensure that the glass beads in the marking coating adhere firmly. Here are a few:

1. In the process of use, glass beads of different sizes are exposed and fall off successively with the wear of the marking line, so that the marking line can continue to reflect light. The graded glass beads should comply with JT/T 446~2001 “glass beads for road marking”.

2. A large number of on-site test data prove that the glass beads scattered on the premixed surface often fail to meet the requirements listed in the table above, and the glass beads of various particle sizes are not graded properly, and even some of them are out of grade, which affects the continuous reflective performance of the markings line.

Many people driving at night may be quite clear about that and often found that the traffic signs on the roadside are very bright. However, people may not be clear about the cause of this phenomenon. Then, what is the significance of the application of reflective glass beads on the road?

The significance of the application of reflective glass beads on the road

The glass bead is a newly developed material in recent years. It has a wide range of uses and special properties. It has a very small diameter, light weight, and high strength. When it is added to the coating, it can be used to make the reflective coating that adults need. At the same time, it has a very strong reverse regression reflection performance, which can reflect light directly to the backlight to a large extent. Therefore, there is a strong regression reflection effect, and the application of reflective glass beads on-road safety performance has been improved greatly.

The paint added with reflective glass beads on the road can complete the reminder function of the night signs without any additional power supply. Therefore, the application of reflective glass beads in traffic signal signs, outdoor facilities, road markings, and other night warning signs can greatly improve the night recognition of these signs, play a very good role in guiding and warning, and provide a stronger security line for drivers who drive at night.

High index reflective glass beads are widely used in real life. At the same time, its application is of great significance. Our company is one of the glass bead media suppliers, we specializes in the production of reflective glass beads with stable product performance and favorable prices. Welcome to buy!

We found that in many living buildings, glass beads are often used in residential buildings. Why does this happen? Why are high-performance hollow glass beads used in the construction field?

The high-performance hollow glass beads have very good advantages. It has a good anti-corrosion effect, good anti-leakage effect in the actual use process, and it also shows very good effect in the specific use process. Its heat preservation effect is suitable for outdoor use, and its corrosion resistance is obvious, so this kind of 3M hollow glass beads are very common in the field of architecture!

Not only is the sprayed glass microbeads used in the construction of highways, but we will also use the sprayed glass microbeads in our daily life. The following introduces the specific characteristics of shot glass beads. There is also a certain understanding that when using it in the future, there will be no problems.

First of all, the properties of shot-peened glass beads are well known. It is a soft and hard material. At the same time, its production is mainly made of high-quality materials.

The second is that it also has a certain mechanical strength, has good elasticity, can be reused, and is not easily broken, and has a longer service life, which is up to 3 times the service life of ordinary glass beads.

Then there is the good application of shot-peened glass microbeads. Its strength is very uniform. After use, the brightness coefficient of each part during the blasting can be kept uniform, and it is not easy to leave a watermark. Glass bead is a kind of abrasive material. Compared with other materials, its service life is very long. It is mainly made of non-alkaline soda-lime glass material. It has good chemical stability and will not affect The processed metal causes any contamination.

Shot blasted glass beads have a smooth surface without any impurities and have a good finish. They are essential materials in related industries. The application range of different types of glass microbeads is also different. Other glass products are well received by new and old customers in the market.TenRoads products have high-quality assurance and have been widely sold in various regions of the country.

In order to achieve clearer road markings and provide signal support for vehicle pedestrians, better transparent glass beads can be selected to enjoy better results. If you want to make the overall presentation better, you can start from a more reasonable angle, demand better quality assurance, and have more prominent advantages.

For example, road reflective glass beads can have a better reflection, wear resistance, and corrosion resistance, so there is a better guarantee for improving road safety. Choosing a higher quality porous glass microbead can provide better help for road marking zebra crossings, banned crossings, etc., and achieve better performance assurance, so it will be more prominent in reliability.

High-quality transparent glass beads are a more reliable guarantee for the use of road reflective glass microbeads, and the final sense of quality will be more prominent, so the advantages will be more obvious, and the sense of quality that can be achieved will also be Better, the quality assurance obtained will be significantly improved, and the quality of the final presentation will be better.

There are many types of glass beads, and transparent glass beads are definitely one of the more widely used. As the main type of porous glass microbeads, it can show better results in various warning signs, and it can be better in reliability. It can also bring a better sense of quality in the end. The sense of quality will also be more prominent.

Most of the road glass beads are transparent types, which can be better in warning effect, and can also bring a more prominent sense of quality and the protection sought. If we want to make the ability of wear resistance, compression resistance, heat resistance and cold resistance stronger, we can achieve better warning construction, and the final sense of quality can definitely bring a better embodiment.

The selection of high-quality road reflective glass beads is very important. At this time, the selection of transparent glass beads can have better performance, and the road reflective effect is more prominent. For the safety of pedestrians, clearer traffic warning signs definitely provide more safety guarantees for night driving.

The new material glass microbeads made from borosilicic acid as raw materials have a wide range of uses. For example, sandblasted glass microbeads can be used as wear-resistant materials or as high-grade thermal insulation coatings, which can be better realized. The aesthetic effect, abrasion resistance, and thermal insulation properties are widely used in artificial agate and artificial marble.

The silver-plated glass beads we provide have a very good performance in improving the color effect of the coating and the corrosion resistance and wear resistance after spraying. Of course, the use of glass spheres is not limited to this. More often, it can also perform well in the production of emulsified explosives, so it is definitely critical to reasonably choose a better supplier.

It is also more affordable to choose the hollow glass beads we provide, so that any time you choose a product, you should start from a more professional perspective, and it will have a more prominent performance than the quality assurance that you ultimately seek. In order to obtain better quality assurance, it is better to make a reasonable choice from a more professional perspective.

Shotblasting glass beads are widely used in various industries due to their advantages of a lightweight, low thermal conductivity and high strength.

Advantages of Shotblasting glass beads

First of all, shotblasting glass beads have both soft and hard characteristics. Because they are produced by using special materials, they have certain mechanical strength. At the same time, they can be used repeatedly. They are not easily broken. More than 3 times.

The uniformity of shotblasting glass beads is very uniform, and it does not leave a watermark. It is superior to any abrasive material, and it is longer than any other medium except metal abrasive materials. Very stable in nature.

Shotblasting glass beads have a good finish and can effectively reach international and domestic standards, so you can definitely use them with confidence.

At present, the hollow glass beads are sorted from fly ash at home and abroad, which can be roughly divided into two methods. One is to use a dry method to sort hollow microbeads; the other is to use a wet method to sort hollow glass microbeads. The specific adoption method can be determined according to the actual situation.

In China, the dry mechanical sorting method is adopted, and there is a sorting hollow glass bead equipment of gravity separation sieve system, which can process 30t fly ash daily. This set of sorting process includes the selection of hollow beads and can select a variety of particle sizes of iron, carbon, and hollow glass beads.

Hollow glass bead sorting device

The hollow glass beads sorting device consists of three main parts, namely a sorter, a separator, and a collector.

The separator is a gravity separation method. The separator is composed of three sedimentation boxes of different sizes. At the lower part of each sedimentation box, there is a discharge device. When the airflow containing fly ash enters through the air inlet pipe In the settlement tank, due to the increase of the cross-section of the airflow channel, the gas flow rate rapidly decreases, and the fly ash is gradually reduced by the gravity itself. According to the principle of an equal drop, heavier coarse particles, honeycomb glass Most of the quartz, mullite, solid beads, iron beads, and large carbon particles are settled in the separator. There are also some small hollow glass microbeads, ultrafine microbeads, etc. that enter the separator with the airflow.

The separator uses the inertial centrifugal force acting on the particles during the rotation of the airflow to separate the particles from the airflow. The main form of the separator is a cyclone separator group. The small hollow microbeads passing down the channel of the subsidence box enter the separator with the airflow. After the separation of the two-stage cyclone separator group, most of the small hollow microbeads can be separated. Come out, the very small amount of ultrafine beads left with the airflow and finally enter the collector.

The collector is at the end of the sorting device. It is both a purification treatment device and a collector for recovering ultrafine beads. The process uses a pulse bag collector, which can collect most of the ultrafine beads not selected by the separator.

"Debittering" olives is a complex process. In their natural state, olive fruits are rich in a compound called phenol, which is unacceptable. If olive is to be squeezed into oil, its phenolic substances are not important. Most of them just need to be pressed to produce meat (just wait for the oil to be squeezed). However, edible olives must remove phenolics from them before they are eaten.

At present, the main way to "debitter" olives is to soak them in water, or brine, or brine, and then soak them in sodium hydroxide solution. Later, it was found that tiny resin beads could be used to accomplish this task.

Ion exchange resin is a high porosity polystyrene resin, which adds additional chemical groups to capture different kinds of molecules. There are many kinds of ion exchange resins on the market, usually in the form of hollow beads. These beads have larger surface areas than their volumes, maximizing the number of polymers available for reactions. Beads are also easy to handle.

If this discovery can be translated into commercial operation, the market will begin to have ion exchange resin beads for sale, the saltwater immersion stage can be shortened by three quarters, the alkali step can be completely eliminated, saving a lot of time and materials. Because the beads themselves can be properly treated to remove and treat phenolic substances, which can be recycled. Therefore, ion exchange beads may make olive processing cleaner, faster and cheaper.

The Fmoc method is a new method for solid phase synthesis of peptides developed by Carpino and Hart based on the Boc method.

The fundamental difference between the Fmoc ltd /t-Bu(9-fluorenylmethoxycarbonyl/tert-butoxy) strategy and the Boc/Bzl strategy is the use of alkali-removable Fmoc is a protecting group for α-amino group, the side chain is protected by t-Bu which can be removed by TFA, and the solid phase carrier Wang resin with acid-sensitive linking arm is used, and the final step of the synthesis is removed by TFA. Han Xiang et al. successfully synthesized the 32-peptide thymosin α 1 by Fm oc solid phase method, starting from Fm oc-Asn(Trt)-W angResin, Boc protecting the side chain amino group of Lys, and tert-butyl ester group (O-t-Bu Protecting the side chain carboxyl group of Asp and Glu, t -Bu protects the side chain hydroxyl group of Ser and Thr, and trityl group (Trt) protects the side chain amide group of Asn, and the total synthesis yield is 33.2%, and the purity is >98.8%.

The Fmoc protected amino acid is sensitive to bases, especially secondary amines, and can be removed with piperidine at room temperature. Under these conditions, Z-based, Boc-based or other amino protecting groups are unaffected.

The Fmoc protecting group is stable to acid and can be removed under mild alkaline conditions. It can be used orthogonally to acid-sensitive side chain protecting groups, and has the advantages of mild reaction conditions, less side reactions, and high yield.

Purification of the product is also facilitated when the polyaryl analog of the Fmoc protecting group is attached to the N-terminus of the polypeptide and protein. At the same time, the Fmoc group has characteristic ultraviolet absorption and is easy to monitor and control the reaction, so it is more and more popular.

Moreover, with the development of the peptide synthesis industry, the cost of Fmoc to protect amino acid raw materials is greatly reduced, and the Fmoc method has gradually replaced the Boc method and is widely used in solid phase synthesis.
