Cutting process and production process 1. Cotton blending: According to the different requirements of customers, the fiber cotton is proportioned according to different proportions. After the initial weight is weighed, it is poured into a blender and the machine is rotated to stir.2. Opening: Send the agglomerated fiber to the licker-in roller device through rollers, and send them in turn. After the fiber is opened, it will be sent to the secondary opening by a fan.送 装置。 Send device.After the second feeding, the fiber mass is sent to the cotton mixing box by the fan, and mixed by the bucket vibration.更多3. Carding: The thickness of the lathe is evenly divided by the Xilin and Doffer.

It belongs to a class of foamed rubber. Foam is a type of polymer with voids in the middle, including many types.The dirty kind of foam you often see when you were a kid is a foam that is cut into a loaf and sliced by a shabby truck. It is actually foamed polyurethane.It is yellow and very soft, and is often used on mattresses!Sponge is a soft foamed polyurethane rubber. Polyurethane is one of the most common polymer materials in life. It is widely used to make various sponge products.And elastic materials that can be used for shock absorption and anti-friction, such as shoe soles, tractor tank track substrates.更多Pearl cotton belongs to a category
It can also be said that it is a shock-proof sponge, filled with shock-proof effects. This is a special sponge that is lighter than ordinary sponges and has excellent physical properties and strength such as stretching. It is more important that it also has a very good Seismic performance.Even when shock-proof sponges are added to water, they can still maintain good chemical stability; they can be classified according to their density and hardness and coloring.Shockproof sponge is a kind of special material produced by sponge factory. It can be used to make upholstered furniture. It can also be used as a cushioning material or as a sound insulation material.更多The sponge master produced by the sponge factoryMore
Usually refers to the packaging of electronic components or the inner packaging of electronic products.He is a foamed material whose greatest feature is antistatic and shockproof.It can well protect electronic products from static electricity and external impact forces.The application of high-density electronic cotton packaging linings is mainly concentrated in two areas: one is the electronics industry, and the other is the instrument industry.Because electronic products are mostly electronic components, if they are not careful, they can be easily damaged by static electricity in life, so the antistatic property of the packaging is very important.The second is the instrument industry. Most of the instruments are precision products.更多In daily use, we are slightlymore
