Menghua Chemicals (MHCC) implements full process quality control in calcium carbide production, processing and crushing, calcium carbide filling, and finished product delivery. Sampling and testing are carried out at every stage of production, using the commonly used calcium carbide and water decomposition method in the calcium carbide industry to detect acetylene values. At the same time, the company uses high-end precision instruments to analyze the main components and impurities of calcium carbide.

In terms of particle size, we control the hardness and diameter of the sieve plate to ensure the precise size of the carbide after crushing. During the crushing process, a dedicated person is responsible for monitoring the size. At the same time, the calcium carbide powder from the crushing process will be recycled for the production of PVC. Strictly control the weight of calcium carbide powder inside the packaging.

In terms of calcium carbide packing and transportation, we keep the calcium carbide drums clean to ensure weight, quantity, and quality. During the loading and unloading process, we ensure that the outer packaging is not damaged. Fill with Nitrogen to ensure the stability of calcium carbide. Our company can accept quality testing from any international laboratory. 

Before export, the customs will enter the factory to inspect the quality, weight, gas yield, dangerous goods transportation labels, and particle size of the exported calcium carbide. Ensure that the exported calcium carbide meets the national export standards.We only produce high-quality calcium carbide and welcome friends from all over to visit our factory for business negotiations.

蒙化化学在电石生产、加工破碎、电石灌装、成品出厂，实行全流程品控。在生产的每一个环节进行取样检测，采用电石行业常用的电石与水分解法，检测乙炔值。同时，公司采用高端精密仪器对电石主要成分及杂质进行分析。破碎粒度方面，我们对筛板硬度及直径的控制，确保了电石破碎后的尺寸精确。在破碎过程中，设立专人负责监控尺寸的大小。同时，将破碎过程中的电石粉进行回收用于PVC的生产。严格控制包装内电石粉重量。电石灌装及运输方面，我们保持电石桶的清洁，保证重量、数量和质量，在装卸过程中，保证外包装无损坏。充装氮气以确保电石的稳定性。

出口前，海关将进入工厂对出口的电石质量、重量、发气量、危险品运输标签、粒度进行检测。确保出口的电石达到国家出口标准。我公司可接受任何国际实验室的品质检测。我们只做高品质电石，欢迎各地朋友来厂参观、商务洽谈。
