How to remove RTV silicone

How to remove rtv?

For clothing stained with this RTV silicone, the silicone should be moistened with turpentine to soften it, and then removed with gasoline. For already dry spots, apply cream or artificial butter first, then wipe with gasoline or turpentine, then wipe with 10% ammonia until all the silicone are cleaned. You can also use turpentine to wet the silicone or apply a mixture of white porcelain clay and turpentine to the silicone. After 4 to 5 hours, the RTV silicone can be wiped off and washed with hot soapy water. In addition, the solvent chloroform, turpentine and a mixture of chloroform and carbon tetrachloride (1;1), and a mixture of diethyl ether and ethyl acetate (1;1) are  very effective in removing oil base and dry oil spot.

 

Such stains on the dyed fabric are first wetted with a pure hot glycerin solution, and then pressed with a cotton ball which touches glycerin tightly on the stain (no rubbing is allowed, rubbing causes changes in the color around the stain).

 

For such stains on white clothing and non-fading clothing, use concentrated alcohol or concentrated alcohol and a mixture of 5% ammonia in water. When a colored wash stain remains on it, it should be treated with a 3% sodium dithionite solution. When the garment is white cotton and linen, it needs to be removed with an aqueous solution of bleaching powder or an aqueous solution of a mixture of bleaching powder and washing soda ash.

 

For such stains  on white clothing and non-fading clothing, use concentrated alcohol or concentrated alcohol and a mixture of 5% ammonia in water.  you should use 3% concentration of sodium dithionite solution to deal with when the dress is white cotton and linen, using aqueous solution of bleach or aqueous solution of bleach and washing soda ash mixture of removal.

Textile And Printing Industry Wastewater

SIZING SOLUTION RECOVERY

Printing and dyeing sizing wastewater alkali reuse technology patent is the use of ceramic ultrafiltration membrane technology to concentrate sizing wastewater, which permeates directly backs to the sizing process, water and caustic soda are reused fully after treatment resulting in zero discharge. The technology has achieved industrial scale applications and access to a national invention patent.

 

  1. Dyeing and sizing wastewater contains a large amount of refractory slurry, the slurry into the sewage treatment system, increasing the difficulty of biochemical treatment, making sewage treatment costs increase. Printing and dyeing sizing wastewater also contains a higher concentration of caustic soda (0.5% ~ 7%) and a certain amount of refining agent, with a high recovery value.

 

  1. Using uf membrane technology, the printing and dyeing sizing wastewater concentration treatment, membrane treatment of the permeate directly to the sizing process, including water and caustic soda, etc. can be completely reused to achieve zero discharge of sewage treatment.

 

Refined water from a dying plant in Nantong is treated by ceramic membrane technology, project design daily capacity is 500m3 or more, yield meets the workshop reuse requirements.

 

INDIGO RECOVERY

The dye wastewater containing indigo is characterized by a dark blue color due to the presence of the dye not fixed to the fiber during the dyeing process.

 

The primary use for indigo is as a dye for cotton yarn, which is mainly for the production of denim cloth for blue jeans.

 

The wastewater containing indigo is characterized by a moderate amount of chemical oxygen demand (COD), pH, suspended solids, dissolved solids and a dark blue color, due to the presence of the dye not fixed to the fiber during the dyeing process.

WASHING EFFLUENTS

Washing is a finishing process applied to fibres, yarns, and fabrics.

 

Washing is normally carried out in hot water (40-100°C) in the presence of wetting agent and detergent. The detergent emulsifies the mineral oils and disperses the undissolved pigments. The choice of the surfactants may vary also depending on the type of fibre. Mixtures of anionic and non-ionic surfactants are commonly used. An important factor in the selection of a surfactant is its effectiveness in strongly alkaline conditions.

 

Washing effluents are mainly composed of soap, grease, synthetic detergents, detergents and a small amount of bacteria, coliform bacteria, viruses, and other harmful substances, has become an important source of water pollution.

 

After washing effluents are discharged into natural water, dissolved oxygen is consumed and slightly toxic to aquatic organisms, which can cause fish malformation and eutrophication caused by phosphate solvent.

LED Display Overview

A LED display uses light-emitting diodes as a video display. Just like a big TV which can be used both outdoor and indoor.

It is widely used in the hall, hotel, exhibition room, showcase, square, sculptures, symbols, building etc. Because of LED display dynamic and constantly changing, vivid images and videos, live to broadcast, etc many advantages.

Nowadays is most popular for advertising purpose and showing purpose.

The first question before buying a Led display is "where will it be used, Indoor or Outdoor?"

LED Pixel Pitch

 

One of the most important knowledge when you buy a Led Display.

Pitch stands in distance between the pixels. Example P10 = distance between pixels =10mm.

Pixel can exist of more leds. In Full-color solution, they have 3 leds in 1 pixels (Red Green Blue)

Pitch will determine the viewing distance and the resolution. The smaller the pitch the smaller the viewing distance.

To determine the right pitch is not easy. First, you have to determine the viewing distance before you can choose the pitch. Indoor will mostly have a small pitch. (P3-P10) because the minimum viewing distance is small. Outdoor will have a bigger pitch. (starting from P10...)

LED Display Resolution

 

LED screen resolution is the basic measurement of how much information a screen shows based on the total number of pixels within the display area and is a significant factor in determining image quality.

The display resolution of Led display device is the number of distinct pixels in each dimension that can be displayed.

It is usually quoted as width × height, with the units in pixels: for example, "1024×768" means the width is 1024 pixels and the height is 768 pixels.

When the Led Display should display clear text. The resolution is very important (like information displays) Most characters on an information display should be around 8 leds high and 5 leds width.

In order to show a good video effect on led display, it will need total resolution 50,000 pixels at least.

In following pages, we will share more LED display guide information. Any questions, please feel free to contact our sales engineers.

 

LEDFUL, founded in 2008, is a professional led display company in China. If you want to buy led screen outdoor, just contact us! We welcome merchants from all over the world to cooperate with our factory for mutual benefit and win-win, and jointly create a better future.

How To Deal With The Faults Of Hf Welding Pvc?

 

If the time of hf welding pvc is too long, there are often some faults. After the failure occurs, users must find and deal with it in the first time and solve it in time. For different faults, the solutions are different. The following solutions are listed here for everyone:

 

If the welding effect is not ideal or it cannot be welded or the workpiece is damaged when it is in the process of hf welding pvc, we can not think that it is the problem of equipment. It could be other problems. For example: equipment setting error, blown fuse and so on may happen.

 

Common failure analysis and solutions:

  1. If there are bubbles in the process of hf welding pvc with workpieces, it is not directly related to the equipment usually.

(1) situation of loose connection

it is possible that the flow meter of the gas regulator has been damaged or blocked with sundries.

 

(2) there may be sundries on the surface of the workpiece.

 

  1. it is not directly related to the equipment if the voltage is unsteady in the process of hf welding pvc with workpieces.

(1) loose connection wire between the main machine and the extension machine

 

(2) the induction coil is out of shape or there is no distance between the coil and the coil, or the induction coil is loose.

 

If above circumstance has been excluded, it still cannot work normally, users should turn off equipment and ask professional technicians to repair the equipment. If the device suddenly stops working in the process of use, you should immediately turn off the device and check the host, and wait for 3-5 minutes before starting up. If it can not work normally after turn it on, ask professional technicians to repair the equipment. But users also need to be skilled in using the equipment, and can make an accurate judgment of the corresponding fault to timely solve the fault, reduce the waste and loss of equipment and production.

POWER TROWEL

A power trowel also knows as a power float. It is a common small construction equipment used to create a level, smooth finish on a large, flat area of concrete, such as an interior floor, or a poured patio slab for a deck by a lot of construction companies and contractors. We use multiple blades that rotate in a safety cage, driven by petrol engine.

 

With so many sizes of power trowel China in our company, you can choose the most suitable power trowel in accordance with the working area. In general, if you’d like to level a small area of under 1000 square feet, choose a walk behind power trowel with 24 to 36 inch working diameter is good enough. The working diameter of power trowel is 24 inch, 30 inch, 36 inch, 46inch, just select the most cost-efficient one from us. Getting both floating and finishing combined blades to smooth the concrete in a series pass. Also, optional petrol engines are available, the Chinese local brand, Robin brand, and Honda.

 

As we all know, it is awfully crucial that you should do your concrete finishing job in time. When power troweling overworks the concrete surface, it in effect compresses the top layer of the slab, closing up the naturally porous "vents" or pathways in the aggregate that allow moisture within the concrete slab to move to the surface and to evaporate out of the slab.

 

Running power trowel in appropriate speed helps to keep the machine from digging into the concrete and ruining your progress.  Once you’ve gone up and back over the entire slab, turn perpendicular and go across the entire slab. This technique will help to finish any spots that were missed on the first pass.
