What is the meaning of shoe ingredient pu?
The shoe ingredient pu refers to the fabric. Pu is the abbreviation of poly urethane in English and the chemical Chinese name is “polyurethane”. Pu skin is the epidermis of polyurethane.
Features:
Pu leather has excellent wear resistance, good softness and excellent tenderness. Pu leather is a synthetic imitation leather with natural softness, even if it is soaked in gasoline for more than half an hour, it is still soft.
The appearance of pu leather is very similar to that of real leather. Although it is not as durable as genuine leather, it still has many advantages compared with genuine leather. Pu leather has a good appearance, bright colors, softness and comfort, and is easier to take care of than dermis. Especially compared with expensive dermis, it has a very high performance-to-price ratio.
Extended data
Maintenance method
1. Clean with water and detergent, avoid gasoline or liquid scrubbing.
2. No dry cleaning, only water washing, and the washing temperature should not exceed 40 degrees.
3, can not be exposed to the sun, pu leather coat need to hang bag collection, can not be folded.
History of development
PU coating on the surface of fabric first appeared on the market in the 1950s, and in 1964, DuPont developed a kind of PU synthetic leather used as upper.
After the Japanese company established a production line with an annual output of 600000 square meters, after more than 20 years of continuous research and development, PU synthetic leather has increased rapidly in terms of product quality, variety and output.
Its performance is more and more close to natural leather, and some properties are even better than natural leather, which is indistinguishable from natural leather.

What are the paint production equipment?
Paint production equipment mainly include: pre-dispersion equipment, grinding equipment, filtration equipment.
1. Pre-dispersion equipment: pre-dispersion is the first working procedure of paint production. Through pre-dispersion, pigments and fillers are evenly mixed, and at the same time, the base material replaces the air adsorbed on the surface of some pigments, so that the pigments are partially moisturized and the pigments are preliminarily crushed under the action of mechanical force. In the production of color paint, this process is a matching process of grinding and dispersion. In the past, the grinding and dispersion equipment of color paint was mainly roller mill, which was matched with various types of pulp mixer. In recent years, grinding and dispersion equipment is mainstream with sand grinder, and its matching is also changed to high-speed disperser, which is the most widely used pre-dispersion equipment for paint production equipment at present. The market price of the high-speed disperser is currently fluctuating within 10,000 yuan.
2. Grinding equipment: grinding equipment is the main equipment for the production of color paint, and its basic form can be divided into two types, one kind of grinding medium with free movement, and the other without grinding medium, which rely on grinding force for grinding dispersion. The commonly used grinding and dispersion equipment are sand mill, roller mill, high-speed disperser and so on. The sand mill has high dispersion efficiency and is suitable for medium and bottom viscosity paint paste. Roll mill can be used for the production of paste materials with high viscosity. The market price of sand grinder is generally less than 15000.
3, filtration equipment: in the paint manufacturing process, it is still possible to mix impurities, such as adding color, fillers, may bring some mechanical impurities, with sand grinding dispersion, paint paste will be mixed with broken grinding media (such as glass beads). In addition, there are pigment particles that have not been fully ground. The commonly used equipment for paint filtration are compass screen, vibrating screen, bag filter, tube filter and self-cleaning filter and so on. Generally, appropriate filtration equipment is selected according to the fineness requirements and output of paint. The market price of bag filter generally varies from 15000 to so on. Tubular filters generally range in price from several thousand to ten thousand.
How much film is coated in plastic woven bag coating compound machine per hour
Not necessarily. You need to see your equipment model. The production capacity of the equipment is generally introduced in the specification. You can use the product of width and speed to calculate the capacity per unit of time.
