1. For this situation, it is caused by the production reasons of the silicone manufacturer itself, and the guaranteed raw materials and machinery and equipment are under normal circumstances, and are caused by the production of personnel and the problems of The Times.
2. Generally, manufacturers of silicone products will confirm the hardness requirements of the samples required by customers to ensure that the hardness requirements required by customers can meet the standards when mixing. After mixing, the temperature adjustment of the machine equipment is completed from both the pressure and the outlet hole, and it is necessary to determine how long the vulcanization time needs to achieve the best effect. So after checking, you can find the reason from the operation method.
Silicone rubber products hardness unqualified solution:
1. As for the hardness of the product, it does not need to be too hard or too soft. Generally, it is necessary to make enough products and properly adjust the irregular lifting time of silicone rubber products.
2. Check whether the product can reach the hardness according to the previous mold products. If the mold temperature is not enough to increase two or three degrees, the time will be extended. If the feel is too hard and brittle, it is easy to break in the practical process in the future.
3. You can increase production by reducing time. If the time is reduced or it is too brittle, the temperature can only be lowered until there is no undesirable phenomenon of bubbles.
Therefore, silicone rubber products are a new type of polymer elastic materials. Excellent resistance to high temperature (250~300) and low temperature (-40~-60). It has good physiological stability and can withstand the harsh conditions of repeated disinfection. Excellent resilience, small long-term deformation (20048 hours not more than 50%), breakdown voltage (20-25KV/mm), ozone resistance, UV resistance, radiation resistance, etc. Ordinary silicone tube: medical silicone tube, food grade silicone tube, industrial silicone tube, silicone shaped tube, silicone hose accessories.
