3A sanitary-o-rings

91视频H污污 O-rings and seals provide 3-A sanitary O-rings for equipment related to dairy production and processing. The 3-A hygiene standard was developed by the U.S. food and dairy industry to set policy regarding the production and use of sanitary devices. 3-A O-rings comply with 3-A Standard 18-03 and relate to multi-purpose rubber and rubber-like materials that are approved for contact with dairy equipment surfaces and dairy equipment cleaning products. The 3-A standard is recognized and followed at the international level.

Advantages of Nitrogen Freezing to Remove Burrs

Advantages of nitrogen freezing to remove burrs 1. The operation is simple, ordinary workers can operate the machine skillfully after a period of training, and the advanced automatic control system can prevent workers from misoperation 2.High production efficiency, a frozen deburring machine average daily processing amount equivalent to 50-80 skilled workers trim the work load 3.High trimming precision, it can remove very small and hidden flash, without limited by product shape, high pass rate and stable trimming quality 4.Do not damage the surface of products, improve the appearance of products quality, increase the service life of products 5.Small area, a frozen trimming machine and auxiliary equipment only 10 square meters 6.Reduce the use cost of the mold and the cost of the glue material. The equipment does not need the edge tearing, only the flying edge is required to be as thin as 0.2mm, the overflow groove is as small as possible, and the flying edge allowance is only 1/5-1/10 of the ripping mold.

Why the rubber sealing strip products will appear bubbles？

Why the rubber sealing strip products ?will appear bubbles？ Automobile sealing strip is one of the important parts of the car, widely used in the door, window, body, seat.Car sealing strip, chair, skylight, engine case and trunk and other parts, with waterproof, sealing, sound insulation,dustproof, frost proof, shock absorption, heat preservation and energy saving important role, car sealing strip can improve air tightness, prevent wind and rain into the compartment； Once the aging of the car seal strip is damaged, it will cause the car leakage, and the wind noise of the car will increase, and the rain leakage will easily make the body rust.Then the car door seal and other rubber seal products in the production process of some problems may lead to the door seal and other rubber seal surface bubble phenomenon, what is the specific reason? Analysis of causes: 1.The auxiliaries in the compound are not evenly dispersed during mixing 2.Vulcanizing agent impurities more, small molecule impurities into early decomposition, bubble residual products 3.Mixing temperature is low, there is moisture, moisture volatilization is not net, when the temperature is high, the rubber is easy to melt when the sulfur is added to the opening mixer, or the sulfur is burnt 4.The glue material is not placed enough time or not placed on the production and use 5.Rubber heating is not uniform so the surface is rough 6.When the rubber material is hot smelted on the opening mill, the surface is wrapped with air, and the type of rubber material has the phenomenon of hiding air 7.Temperature control is not strict and there are air bubbles on the surface of semi-finished parts How to resolve ? 1.Optimize the production formula, choose easy dispersing type of additives to replace the existing additives, increase the application of dispersant, homogenizing agent and other processing additives, improve the dispersion performance of various additives 2.Mixing rubber using internal mixer two-stage process production, a period of mixing temperature increase, so that the moisture in the raw material is fully volatilize, glue after placing and then two-stage mixing, temperature control in the temperature range of sulfur and accelerator, avoid burning time short or burning 3.Strictly control the placement time of semi-finished products, so that all kinds of additives fully diffuse, improve the uniformity of the rubber material, and is conducive to the recovery of stress and strain under mechanical action 4.The glue hot smelting should be uniform, and the operation mode of separating the glue supply from the type in the hot smelting is adopted to improve the smoothness of the surface of the glue 5.Adopt the extrusion process to extrude the rubber materialand the surface of the type of adhesive material is no longer trapped air phenomenon.
