Impulse refers to the welding current waveform is discontinuous, current size changes.

Generally speaking, pulse type spot welder refers to the sinusoidal alternating current is SCR, divided into sections of current, commonly known as pulse welder. In other words, pulse mode of operation refers to the mode of operating only once every certain interval.

At present, single pulse and double pulse are mostly used in welding.

Conventional pulse gas welding: only one pulse. All the peaks of a monopulse are the same like NNNNN. Pulse gas welding machine is the use of pulse current to achieve droplet transition welding mode, no splash, deep penetration, fine grain, high weld strength, suitable for all-position welding, from 20 a to 500A can achieve stable quality welding, welding performance is far better than the ordinary gas welding machine, is the mainstream direction of welding machine development. Double pulses are equivalent to the superposition of two single pulses with the same period and different phases. In other words, one period may have two peaks: nNnNnN.

Double pulse gas shielded welding is a welding method developed on the basis of pulse gas shielded welding. It is a welding method with alternating changes of two pulse gas shielded welding methods with different current sizes. It is mainly used in the welding of aluminum alloy, and it can produce the effect of fish-scale pattern without swing, similar to the effect of ac TIG welding. In addition, this welding method can effectively control the heat input, which is similar to the pulsed argon arc. It can be fully welded without penetration, and is suitable for all metal welding. It is an advanced welding method.

Application advantages of impulse welding:

There is no spatter in the welding process, the heat affected area is small, especially for the thin plate welding has obvious advantages, the consistency of energy waveform output can be guaranteed from beginning to end, and the fusion depth and weld pile height are fully consistent. Double pulse can be used for welding aluminum alloy and stainless steel. No spatter during welding, easy to operate, suitable for manual and automatic welding, arc stability, adjustable depth, beautiful shape, less porosity, excellent mechanical properties and other characteristics!

1.Use: A single group of silicone glass glue can be used immediately. It is easy to type it from the bottle with a glue gun, and a spatula or wood chip can be used to trim the surface.

2.Silicone glue drying time   : the curing process of silicone rubber is developed from the surface to the inside. The drying time and curing time of different characteristics of silica gel are different. So if you want to fix the surface you have to do it before the glass gel sheet is dry (acid glue, neutral and transparent glue should be in 5-10 minutes, neutral color glue should be in 30 minutes generally). If the color paper is used to cover a certain place, after coating, it must be removed before the skin is formed.

3.Curing time: the curing time of glass glue increases as the adhesive thickness increases. For example, the acid glass glue of 12mm thickness may take 3-4 days to solidify. But within about 24 hours, the outer layer of 3mm has been solidified. When glued to glass, metal or most wood, it has an anti-stripping strength of 20 pounds per inch at room temperature after 72 hours. If the use of glass glue is partially or completely sealed, the solidification time is determined by the closeness of the seal. In a place of absolute closeness, it is possible to remain uncured forever. If the temperature is raised, the glass will soften. The gap between metal and metal bonding should not exceed 25mm. In all kinds of bonding situations, including airtight conditions, the adhesion effect should be thoroughly checked before the equipment is used. In the curing process, acid glass glue will produce a smell due to the volatilization of acetic acid, which will disappear in the curing process. There will be no smell after curing.

4.Adhesion: A. Wipe the surface of the metal and plastic completely, remove the oil, and then wash the whole surface with acetone except for the plastic. If it is rubber surface, apply sandpaper and rub it with acetone. Please observe the precautions when using acetone. B. Apply the glass glue evenly on the surface of the prepared object. If the two surfaces are glued together, place one side properly first and press the other side to squeeze out the air, but be careful not to extrude the glass. C. place the bonding device at room temperature and wait for the glass to solidify.

5.Seal: the fast drying silicone glue    also can be used for sealing purposes according to the above steps. Squeeze the glass glue into the joint or the seam so that the glass glue is in full contact with the surface.

6.Cleaning: before curing, the quick dry waterproof sealant can be erased with a cloth or paper towel. After curing, it should be cleaned with a scraper or xylene, acetone and other solvents.

Peptide Synthesis Resins

Since Solid Phase Peptide Synthesis(we can also call it spps resins) was first proposed by Robert Bruce Merrifield, the method of synthetic peptides became more popular than liquid phase peptide synthesis because of high efficiency. This method could assemble a peptide chain rapidly through successive reactions of amino acid derivatives on an insoluble support.

The original peptide antibiotics are also biosynthesized and extracted from the culture of polymyxa or aeruginosa. Another synthetic method of peptides is chemical synthesis, which is divided into liquid phase chemical synthesis and solid phase chemical synthesis. The liquid phase method is mainly used for the synthesis of short peptides. The solid phase synthesis method can be used to prepare long-chain peptides, cyclic peptides, and complex. Peptide. The solid phase method is divided into a Boc method and an Fmoc method. It requires the solid phase synthesis of the carrier to achieve the growth of the peptide chain by means of stepwise amino acid condensation. The advantages of solid phase synthesis are ease of purification, shortening of the synthesis cycle, and ease of automation.

Solid phase peptide synthesis(SPPS) support consists of small, polymeric resin beads functionalized with reactive group such as amine or hydroxyl groups, which link to systhesis peptide chain step by step.

Solid phase peptide synthesis(SPPS) resins is insoluble in all common solvents but swells well in most organic solvents. Better swelling degree is benefit for the reaction yields, but for short peptide easy to synthesis, lower swelling degree will be suitable and it will be good at saving solvent.

Solid phase peptide synthesis Resins are rich in variety, complete in specifications and stable in performance.

Typical Applications

A large amount of waste acid is produced in the production of titanium dioxide, a large amount of high-salt wastewater is generated in the post-treatment process, and some titanium dioxide is still lost after the CN filter. On the one hand, the titanium white industry suffers from increasingly strict Environmental constraints, on the other hand, waste acid, water, and titanium dioxide resources are huge. Therefore, titanium dioxide water treatment has received an increasing attention. JIUWU has developed a series of membrane treatment technologies for waste acid treatment, titanium dioxide recovery, and water reuse.

Technical introduction

The membrane process is based on membrane separation technology. The salt and acid in the waste acid, the salt, and water in the waste brine are separated to achieve the acid and salt in the waste acid, and the salt and water in the brine can be reused. The removal rate of the metal salt in waste acid is over 98%, the recovery of titanium dioxide is 99.99%, and the water production index reaches the international first-class standard. The separation membrane is a cross-flow filtration method, which greatly reduces membrane fouling, delays the rate of membrane fouling, and improves ceramic membrane filtration efficiency.

Process

Titanium dioxide production includes two production methods, sulfuric acid, and chlorination. For two different production methods, JIUWU has designed different membrane processes.

Process advantages

Product water quality: The SS is less than 1ppm, the turbidity is less than 0.5NTU, and the effluent water quality is stable;

There is the the Difference between Rubber Mat and PVC Coil Mat.

1. Composition and production technology are different: rubber mat is divided into homogeneous and heterogeneous. Homogeneous rubber floor refers to the floor vulcanized by a single or multi-layer structure based on natural rubber or synthetic rubber. Heterogeneous rubber floor refers to floor mat based on natural rubber or synthetic rubber. The PVC coil mat is a carpet made of polyvinyl chloride resin. It uses polyvinyl chloride and its copolymer resin as the main raw material to make, adding filler, plasticizer, stabilizer, colorant, and other accessories. It is made based on the flaky connected base material by uniform mixing, coating or pressing and kneading technology. It can replace pure wool carpet and chemical fiber carpet.

2. The trick is different: As the strong color absorption of rubber, most of the rubber floor mats have a single color; while the PVC coil mats have bright colors, rich drawings, and strong decoration. Especially it is most widely used in decoration.

3. Installation difficulty is different: PVC coil mat is lighter in texture, convenient and fast in the installation; rubber cushion is heavy and hard to install.

4. Market demand and wear resistance are different: rubber flooring is only used in some high-end occasions, and the scale is small; while PVC flooring is widely used because of its super high-cost-performance ratio, and the infinite market potential.
