Aminoguanidine bicarbonate is synonymous with aminoguanidine carbonate, etc. It is a white and fine crystalline powder. It is soft and almost insoluble in water, insoluble in alcohol and other acids. It will become unstable when heated, and will gradually decompose when the temperature exceeds 50°C. Amino oligobicarbonates are also used in synthetic drugs and dyes. In the pharmaceutical industry, it is mainly used in the synthesis of guanidine furan, pyrazole, ribavirin, and propyl p. It can also be used as a raw material for synthetic pesticides, dyes, photosensitizers, foaming agents and explosives.

The arbitrary 3D space bending and forming of round material with metal cross-section is the special field of Caelong Hardware, KC has more than 20 years of experience in manufacturing such products. KC Hardware has more than 50 sets of wire forming, bending and forming equipment, all imported from Taiwan and Britain, with computerized automatic feeding and bending control, the accuracy of the product's linear length and spatial angle is well guaranteed to meet the demand for high quality products. Types of Wire Forming Service U Shape Wire Forming Such bent products are used to support the display stand, the appearance of the product is demanding, the surface of the product is not allowed to have processing marks and the symmetry of the product should be consistent. Multi Shape Wire Forming This product is bent with multiple 90 degree right angle bends, and because the raw material is made of high elastic gin wire, the material must be annealed before it can be bent and shaped. S Shape Wire Forming Serpentine bending products require a high degree of consistency in the size of each U-shape, the material needs a certain degree of strength, the overall flatness of the product needs to be guaranteed, and the product has a certain load-bearing capacity, so the product needs to be heat-treated and shaped.
