According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles: Calcium Carbonate,Calcium Carbonate, Light Calcium Carbonate Henan Shunbang Chemical Industry CO.,Ltd , https://www.spvcresin.com
In the past, most of the plant protection machinery used by farmers to control crop pests and diseases were manual pressure-lifting sprayers. Due to the short distance of spray, it was time-consuming and labor-intensive. After a long period of use, it was easy to leak water and leak medicine.
Zhao Yufang, a villager from Xifu Village, Lucheng Town, Danyang City, and several new high-pressure self-locking automatic sprayers developed by several farmers, use the high-pressure air inside the machine as the original power to spray the liquid. When the injection ends, the internal self-locking valve It will automatically turn off, it will automatically open when adding liquid, only need to add gas once a year, its range is up to 8 meters.
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
The sprayer also takes the energy-saving route
A new type of high-pressure self-locking automatic sprayer that can spray a hundred acres of farmland with a bicycle pump or a pneumatic pump can be successfully developed in Jiangyanyang, and passed the quality inspection of the National Plant Protection Machinery Quality Supervision and Inspection Center, and obtained the national patent.
