How to solve the problem of pitting in the product after PC material is dyed black with color master batch?

1. The material quality is too poorDoes Guangdong PC material have black ones?theDoes Guangdong PC material have black ones?, use the factory to do wellDoes Guangdong PC material have black ones?Black PC material will do, such as sabic's black 121R material. There wouldn't be this problem.

2. Potting problem description: Potting defects appear on the surface of the product. Solution: If the dispersibility is poor, add dispersant or oil, increase the temperature, and add back pressure. Pay attention to whether there is a problem with the mold and try using other materials. Make sure the baking temperature is sufficient for time. Adjust mold temperature. Description of the problem of "peeling" of products: The problem of peeling of plastic products is closely related to the rupture of fluids caused by high shear forces.

3. Solution: In terms of molding process: Increase the material temperature, increase the nozzle temperature, and slow down the injection speed. Mold: Increase the mold temperature, add overflow increasing grooves, increase the gate size, and modify the gate shape. Description of pitting problem: The pitting problem is usually related to the dispersibility of the material, mold state, baking condition and mold temperature. Solution: If the dispersibility is poor, add dispersant or oil, increase the temperature, and add back pressure.

4. The core reasons for the appearance of pitting on the surface of ABS black material products are usually concentrated on the three links: raw materials, processing technology and molds. Understand the problem,Does Guangdong PC material have black ones?We naturally turn to specific causes and corresponding solutions. In terms of raw materials, black masterbatch is unevenly dispersed in ABS resin, or raw materials are affected by moisture and moisture is vaporized during processing, which is a common cause of pitting.

5. There may be the following reasons for the appearance of silver-like patterns on the surface of products made from PC and ABS crystal compound: Material mismatch: Melting point difference: The melting points of PC and ABS are different, and the melting temperature of PC is higher, while the melting temperature of ABS is lower. This difference in melting points may cause the two materials to not be evenly mixed during processing, resulting in a silver-like pattern on the surface of the product.

6. The raw materials do not meet the standard when drying. PA, PC, and ABS contain water, decompose and discolor at high temperature, and the surface is colored and the depth is different. Solution: Dry according to material standards (ABS80℃/4h, PA120℃/4h), and cover the material barrel to prevent moisture. The color masterbatch has insufficient heat resistance. The toner decomposes at high temperatures in the barrel, and the product turns yellow and gray. Solution: Replace the high temperature resistant color masterbatchDoes Guangdong PC material have black ones?; Reduce the temperature of the barrel and nozzle.

How much is the wholesale price of black fireproof PC material per ton (converted per kilogram)

1. The prices of black PC materials vary greatly. The new modified materials are about 15 yuan per catty, the recycled particles are about 5-5 yuan per catty, and the recycled materials are about 4-26 yuan per catty depending on the product appearance. Price of new materials and modified materials New materials usually refer to unused original polycarbonate materials, while modified materials add flame retardant, toughening and other characteristics on this basis.

2. The price of high-quality flame retardant transparent particles is 26 yuan per ton. The price of ordinary flame-retardant black particles is about 17 yuan per ton. The price of non-flame retardant black particles commonly used in Model I cars is about 15 yuan per ton. The price of general non-flame retardant white particles is about 19 yuan per ton. The price of high-toughness particles is usually around 23 yuan per ton.

Why does PC material make black and colorful?

1. Hello, this is because this material is in the barrel, the water is not fully evaporated, the screw speed is slow, the back pressure is small, the product is not fully compacted, the mold exhaust is not ideal, the mold temperature is small, and the water molecules flow from the product. Due to overflow.

2. Hello, there are the following main reasons for the cost of pc material: 1. The material is not baked well. 2. The gate or flow point design is unreasonable (cannot be directed directly). 3. The material temperature is too high, or the back pressure is too large. 4. The rate of fire is too fast.

3. There are two situations: material flowers are also called silver wires, and the surface of the product is like silver silk. It is caused by water vapor floating on the plastic surface.

How to identify PC materials

PC materials can be identified through various methods such as appearance observation, combustion testing, and professional testing. First of all, observing the appearance characteristics of PC material is a way of preliminary identification. PC materials are usually colorless and transparent, have good optical properties, high transparency, and can achieve a visual effect similar to glass. At the same time, the surface of PC material products should be smooth and smooth, without obvious flaws, defects or damage. These appearance characteristics can be used as the basis for preliminary judgment of the authenticity of PC materials.

Polycarbonate (PC) is a kind of high molecular polymer, its appearance and properties can be used as the basis for identification. Through appearance identification, the appearance of PC plastic raw materials can usually help us to initially determine its category: thermoplastic, thermosetting plastic or elastomer. Thermoplastics are divided into crystalline and amorphous, crystalline usually translucent or opacified, amorphous is opaque or transparent, film-like transparent, hardness varies from soft to hard.

PC plastics can be identified mainly by their appearance characteristics, combustion tests and professional testing methods. PC plastic, or polycarbonate, is a thermoplastic widely used in electronics, automobiles, construction and other fields. To identify PC plastic, you can first pay attention to its appearance characteristics. PC plastic usually has a transparent or translucent appearance, with a smooth surface and sometimes a certain luster.

PC plastics can be distinguished by observing their appearance characteristics, testing their physical properties, and using professional equipment for testing. PC plastic, or polycarbonate, is a widely used thermoplastic with unique appearance and physical properties. First of all, from the appearance, PC plastic usually appears transparent or translucent, and sometimes may have a certain color. Its surface is smooth and the texture is hard, giving people the impression of a good texture.

This concludes the introduction of whether Guangdong PC materials are black and the analysis of the reasons for yellowing of PC materials. slot machine ph casino,slot ph casino,slot machine casino,slot casino,slot ph,BAY888.com The world's leading slot game platform, providing exciting gaming experience and generic rewards.
