What is PVC artificial leather?

What is PVC artificial leather ? The full name of Polyvinylchlorid (PVC) is Polyvinylchlorid. The main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. It is a synthetic material that is loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied worldwide with a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant. This is due to the urgent need for infrastructure construction in Southeast Asian countries.

What is PCB proofing?

Image
The so-called " PCB proofing " refers to the trial production of printed circuit boards before mass production. It is mainly used by electronic engineers to design small circuits and complete PCBs, and then carry out small-scale trial production to the factory. To our knowledge, this process is "PCB proofing" before confirming the product design and testing the product design. PCB proofing detailed process: 1. Contact the manufacturer First, you need to inform the  pcb manufacturer  of the documentation, process requirements and quantities. Take Rigao Electronics as an example. 2. Opening Purpose: According to the requirements of the engineering data MI, it is cut into small pieces on a large sheet that meets the requirements to produce a panel. Small sheets to meet customer requirements. Process: large piece → cutting board according to MI requirements → simmering plate → beer loin \ covering → plate out 3. Drilling Purpose: According to the engineering data, the r...

How to distinguish genuine leather, artificial leather, pu leather and microfiber leather

PU leather and microfiber leather are both artificial leather. PVC is the first generation of artificial leather, PU is the second generation, and superfiber is the third generation. It is the closest in appearance and performance and surpasses leather. So, how to distinguish genuine leather, artificial leather, pu leather and microfiber leather? Let's look at the differences between them. How to distinguish genuine leather, artificial leather, pu leather and microfiber leather: 1. Microfiber is the abbreviation of ultra-fine fiber PU synthetic leather. It is the third generation of non-woven fabrics made of ultra-fine fiber staple fibers through carding and needle punching. The process of impregnation, weight reduction extraction, dermabrasion, dyeing and finishing is finally made into microfiber leather. The ultra-fine fibers are added to the PU polyurethane, so that the toughness, breath-ability and abrasion resistance are further enhanced; it has extremely excellent wear res...

What is ultrasonic cleaning machine?

Ultrasonic cleaning utilizes cavitation bubbles caused by high frequency pressure (sound) waves to agitate a liquid. The agitation creates high forces on contamination adhering to substrates including metals, plastics, glass, rubber, and ceramics. This activity also penetrates blind cracks, holes, and recesses.
