Application of nitrocellulose Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.

Y series vibrating screen is vibrated by the circling motion, its high efficient screen for filter materials into multiple grade according to the gravel size. For the compact structure and the convenient installation, it is the ideal screening device for prefilter of the feed materials before the primary crushing in the quarry site, it also can be used as separation and filtration solely. Vibrating screen adopts cylinder type eccentric shaft vibrator and partial block to adjust the amplitude. The materiel sieve drip line is long and more sieving specifications. The circular vibrating screen can also be used for production classifying in quarry, mine, construction, electricity, chemical industry,etc. Working principle Y series vibrating screen is mainly composed of screen box, screen mesh, vibrator, damping spring device, bottom frame and so on. The side plate of vibrating screen is made of high quality steel plate.It is connected with the beam and bottom seat of the vibration exciter with high strength bolts or ring slot rivets, and cylinder type eccentric shaft exciter and eccentric block are used to adjust the amplitude. Vibrator is installed on the screen box side plate to drive vibrator eccentric block produce high-speed rotation through v-belt by the motor so that could produce large centrifugal force to stimulate the screen box produce a certain amplitude of circular movement.The material on the screen is subjected to the impulse passed by the screen box on the titled screen surface and produces continuous throwing motion.So particles that are smaller than the screen hole pass through the screen so as to achieve classification when material enters the screen surface. Features & Benefits 1. Vibrating screen YA is of several decks whose moving track is round. 2. The moving track of material is very long; the size of material can be separated into several specifications. 3. It adopts cylinder style inspiring vibrator device and eccentric shaft to adjust. It has the features of reliable structure, strong vibrating generation, high screening efficient, low noise, easy maintenance, safe performance, etc. 4. It is widely used in separating gravel and is also suitable for mining, construction material, transportation, energy, chemical industry and so on.
Plain weave copper wire mesh is commonly used for most of commercial applications and for filtration where high flow rate is required, typical uses include chemical processing, RFI electromagnetic shielding, Faraday cages, Tempest shielding, shielding electromagnetic radiation, insect screen, attic ventilation screen, roof soffit, laboratories, snail control, gardens, fireplace screen.
Material: The hexagonal wire mesh has hexagonal holes of the same size. The material is mainly low carbon steel. According to different surface treatments, hexagonal wire mesh can be divided into two types: galvanized metal wire and PVC coated metal wire. PRODUCTS DESCRIPTION About hexagonal wire mesh The hexagonal wire mesh has hexagonal holes of the same size. The material is mainly low carbon steel. According to different surface treatments, hexagonal wire mesh can be divided into two types: galvanized metal wire and PVC coated metal wire. The wire diameter of the galvanized hexagonal wire mesh is 0.3 mm to 2.0 mm, and the wire diameter of the PVC-coated hexagonal wire mesh is 0.8 mm to 2.6 mm. Hexagonal net has good flexibility and corrosion resistance, and is widely used as a gabion net to protect slopes. According to different applications, hexagonal wire mesh can be divided into chicken wire and slope protection wire (or gabion net), the former has a smaller mesh. Feature: Easy construction, no special techniques Strong corrosion resistance and weather resistance Good stability and not easy collapse Good flexibility to increase the buffer force of objects Easy installation and saving transportation costs A long service life Application: Slope protection Bank protection Stair protection Mountain protection Chicken wire Gabion Package: Chicken wire: in rolls and plastic films. Gabion: in bundles and pallets Varieties of hexagonal wire mesh: Hexagonal wire mesh: hot dipped galvanized after weaving.
