1. Raw material quality control
Raw materials are the foundation of the production of chemical products. Whether the quality meets the production standards will affect the product quality to a certain extent. Therefore, the quality of raw materials should be controlled in the process of product quality control. In the process of purchasing raw materials, the company determines the types and properties of materials according to product requirements and on the basis of guaranteed costs. Based on this, bidding is carried out, so as to select manufacturers with high quality and reasonable price, and sign raw material supply contracts with them. According to the nature and influencing factors of chemical materials, the company establishes material storage warehouses, classifies and stores raw materials, prevents raw materials from being deteriorated by external factors, and maximizes the quality of chemical products.
2. Quality control of chemical intermediate products
According to the analysis of the actual situation, the quality control of chemical intermediate products can take the following methods. First of all, do material management and analyze the identification. In the production process of chemical products, the quantity of various materials should be counted, and the identification should be done in different categories, which is conducive to the realization of status traceability. Secondly, for the production process management, the key point of this key quality control is the production parameters of chemical products. If there is a parameter deviation, it should be adjusted. For special chemical products, enterprises should make key controls. The verification status should be adjusted appropriately during the testing process.
Enterprises set quality control standards for unqualified products, and easily remove unqualified products during the implementation process.
In terms of equipment management and maintenance, enterprises need to formulate effective equipment management plans according to their own equipment types, classify different types of equipment, and do a good job of start-up proofreading and regular testing to ensure the accuracy of the equipment. In addition to regular maintenance of production equipment, it is also necessary to set up a preventive maintenance plan, implement the plan, and repair or replace existing problems.
3. Establish quality inspection standards
Excellent production technology and quality standards provide technical support for products, production technology is the foundation of enterprise production, effective guidance for production, and standards are the principles that staff follow Share experience to summarize scientific and effective technological processes, establish relatively complete production processes, obtain good technical guidance, and ensure the accuracy of documents. This method can effectively control product quality and quality inspection standards to protect product production technical indicators, inspection methods and transportation.
