Calcium Carbide Industrial Grade ≥295L/kg is the foundational raw material of acetylene-based chemical industry, and Linkwin implements whole-process raw material proportioning, high-temperature smelting, crushing grading and finished product inspection control system for calcium carbide product, guaranteeing minimum 295 liters acetylene gas yield per kilogram, stable reaction speed and low calcium oxide, carbon residue impurities, avoiding unstable gas output and excessive residue waste for downstream acetylene production lines. Our calcium carbide is grey-black solid lump with different particle size specifications customizable according to customer hydrolysis feeding equipment demands; it undergoes controlled hydrolysis reaction with water to generate high-purity acetylene gas, with adjustable gas generation rate through feeding dosage and water adding proportion, convenient for automatic continuous gas production station operation. Strict impurity control reduces phosphine, arsine harmful impurity content in crude acetylene gas, lowering subsequent gas purification treatment cost and equipment corrosion risk.

In downstream industrial application field, acetylene generated from calcium carbide hydrolysis is primary raw material for vinyl chloride monomer (VCM) synthesis, which is polymerized to produce PVC polyvinyl chloride resin, the world’s second-largest general plastic material widely used for pipe, profile, packaging film, injection molding plastic parts manufacturing. Acetylene gas is also mainstream high-temperature fuel gas for metal flame welding, cutting and metal surface hardening heat treatment in machinery processing industry. Additionally, calcium carbide and its derived acetylene serve as starting material for vinyl acetate, 1,4-butanediol, chloroprene rubber, pharmaceutical intermediates and pesticide fine chemical synthesis, occupying important position in coal-based chemical industry layout. Many overseas acetylene manufacturers frequently encounter low gas yield, unstable reaction speed and excessive harmful impurity gas problems from inferior calcium carbide suppliers; our precise smelting formulation and finished product grading screening process completely eliminate these production obstacles, stabilizing your gas production efficiency and purification operating expenditure.
