Glass insulator manufacturing process:
     The purchasing department shall purchase raw materials from qualified sub-suppliers according to the internal quality control standards of glass raw materials provided by the Production Technology Section. After entering the factory, the quality control center will test the chemical composition, particle size and water content of the raw materials. After passing the inspection, the quality control center shall notify the warehouse manager to classify and store them in batches. The porters request materials from the warehouse according to the needs of the ingredients.
     In order to improve the uniformity of the mixture, quartz sand as the main raw material needs to be dried and other raw materials sent to each bin. The quality control center calculates the formula according to the ingredient statement of the material side and raw materials, and the ingredients room ingredients according to the formula. The quality control center tests and controls the uniformity, moisture content and component content of the mixture. The matched mixture is fed into the kiln by the charging machine and melted. Then, according to the amount of discharge, the temperature, liquid level and furnace pressure to implement automatic control, improve the quality of glass melting. The molten glass liquid is introduced by the feeder and pressed by the press. Pressing process, according to the different product models, adjust the size of the material temperature, material weight and wind pressure. The shorter the material quality of glass, the faster the forming speed. Because of the different temperatures on the surface of the pressed glass, the toughening stress cannot be uniformly distributed. The purpose of temperature leveling is to make the glass softening before the temperature leveling can enter the tempering process. After the average temperature, the glass parts adjust the wind pressure of the air compressor according to the conditions of different products and actual temperature. Glass pieces in
The stress can be formed under rapid and uniform cooling to achieve the purpose of toughening. Quality inspection personnel through random inspection, the head thickness of the glass and the actual size of the threaded hole to check. If the size of the product is found to exceed the tolerance indicated in the size control report, the information should be timely fed back to the operator of the press, so as to find the cause in time and correct the improper operation. After tempered glass, a positive thermal impact test with a temperature difference of not less than 380K and a cold impact test with a temperature difference of not less than 120K should be carried out. After hot and cold impact, it is checked one by one, so that the internal quality of unstable glass pieces self-explosion. The inspectors inspect the appearance quality of the glass pieces after the thermal impact, and remove those glass pieces with stones, cracks, lack of materials, etc. The quality control center should also conduct spot checks on the stamping strength of semi-finished products to determine whether they have good tempering quality. The intact glass parts are packaged and sent to the semi-finished products warehouse for storage for at least three months, in order to further eliminate the potential glass parts with inherent quality problems.
     According to the production plan, the assembly workshop receives qualified parts (iron caps, steel feet, etc.) from the warehouse, prepares cement cement and buffer, and then performs adhesive loading on the glass parts. After adhesive packing, the product shall be steamed for at least 4 hours and watered for 32 hours, and the temperature and humidity shall be controlled to ensure that the adhesive is well maintained and has the expected mechanical strength. After curing the product through the universal testing machine, according to 50% of the rated mechanical failure load, one by one tensile test. The finished product after inspection is qualified, according to the real
International demand from the warehouse to obtain the locking pin, the product assembly, socket, and through packaging, packaging into the warehouse.
