Glass deep processing products are widely used in various fields of people's life, mainly used in construction, transportation, industry, civil, military and other aspects. There are many types of deep-processed glass. According to the purpose: architectural glass, automotive glass, marine glass, aviation glass, electronic glass, special glass, etc. According to the process: cutting glass, edging glass, tempered glass, coated glass, hot bending glass, glazed glass, laminated glass, insulating glass, vacuum glass, art glass and other products. Characteristics of glass deep processing products: many types of products, large changes, high processing precision, strict quality requirements, difficult production and wide application range.
At present, the quality of glass deep-processing products is generally rising, and the product quality is in line with national standards. In particular, from May 1, 2003, products that have not obtained compulsory product certification and have not applied China's compulsory certification mark may not be manufactured, imported or sold. Tempered glass and laminated glass in glass deep-processing products are compulsory certification products. The compulsory safety glass products stipulated by the state must pass the national mandatory “3C” certification before they can be produced and sold. Other glass deep processing varieties should also pass the sampling inspection of many products of the State Bureau of Technical Supervision. Therefore, many glass deep processing enterprises have made improving product quality, strengthening internal quality management, and stabilizing product competitiveness as the focus of enterprise management.
2 quality problems in glass deep processing products
2.1 tempered glass does not meet quality requirements
Mainly in the tempering strength is not enough, the debris particles are larger, the bow shape, the waveform exceeds the standard, the tempered glass self-explosion, the tempered glass wind spot is serious.
2.2 coated glass does not meet quality requirements
Mainly manifested in the appearance of pinholes, stripping, spots, markings, chromatic aberration, etc. in the coated glass. The wear resistance, acid resistance and alkali resistance of the film layer are unqualified, and the film layer is not strong.
2.3 Early failure of insulating glass
Mainly manifested as frosting inside the insulating glass, uneven outer layer sealant (with zebra-like white glue), seal failure, poor LOW-E hollow glass film removal, Low-E glass oxidation, high temperature, high humidity performance test failure, Short service life, etc.
2.4 laminated glass has a short service life
Mainly the degumming of the edge of the laminated glass, the bubble, the film turns yellow, the two pieces of glass have poor fit, and there is a difference in stacking, and the heat resistance, radiation resistance and moisture resistance test of the laminated glass are unqualified.
2.5 product appearance is defective
Mainly manifested as scratches, chipping, corners, inaccurate size, product identification errors, quantity, specifications and actual products do not meet, resulting in rework, return and scrap.
3 Analysis of the causes of quality problems in deep processing products
3.1 Enterprise leaders pay insufficient attention to product quality
There are three factors that affect market competition: quality, price, and delivery time. Among them, the quality is the first. If the quality of the business leaders is poor, only pay attention to the immediate interests and ignore the product quality, the products will slowly lose market competitiveness.
3.2 Production staff quality awareness is weak
The income of production employees is generally linked to production and efficiency. If their cultural quality is not high, their quality awareness is weak, and the quality of products is ignored. Only by pursuing output, regardless of quality and efficiency, there may be potential quality problems in the products.
3.3 The procurement and use of raw materials are not monitored
Purchasing raw materials only depends on the price, neglecting the quality and performance. Due to the use of inferior raw materials, especially the original glass film can not meet the requirements of the specified standards, it will directly affect the appearance quality of the product, and lead to the loss of the inherent quality function of the product. The quality of deep processed products cannot be guaranteed.
3.4 lack of quality control in the production process, insufficient quality inspection execution
In the production process, the lack of necessary testing methods, methods and testing equipment, due to the lack of strict control of the product, resulting in unqualified products flowing to the user, resulting in adverse effects.
