Analysis on the bonding of silicone sealing strip and metal
Silica gel seal is used in natural rubber, metal framework for iron, sandblasting surface with solvent gasoline cleaning, then coated with an adhesive
Agent, appear silicon rubber sealing strips and the metal bond unstable phenomenon, destruction of between rubber and adhesive surface of the adhesive failure, how to solve?
You use a adhesive is not natural rubber and iron special can try other adhesives have many kinds, in the online search
Next data! Sand blasting, the best cleaning after a time, silicone seal and metal sulfide, the pressure is not enough. Is not a recipe.
Oil spray! With the spray will also affect the bonding agent! High temperature curing can also cause adverse effects on bonding! The amount of S increased
Conducive to bonding. Brush the surface of the rubber is not fully dry, because it is the recent discovery of the past or the bonding is good, the selection of surface
The grade of the adhesive is and the rubber match. There may be a reason for the use of the surface before the glue is fully mixed evenly, the material has a special precipitation
Oil separation.
Not sticky place, the temperature is not enough, the adhesive is not enough curing temperature, intermediate temperature because the thickness of the transfer is slow, the temperature is low, bonding
Agent is not enough curing temperature, so do not stick. Improve and reduce the temperature of the curing temperature have been tested, and improve the effect of the temperature seems to be worse. Silicon
Glue dense seal gum rubber burning time shorter nor, brushing adhesive, adhesive oil contaminated or not; can do a ding
Zi Tie verification stick relay, can reach more than 8, then find the product process. Silicone sealing strip of rubber
And fillers and plasticizer has certain influence, wet weather should pay attention to clean the best metal with oven dried,
And then glue it.
Use of the thinner, if the use of paint is mixed evenly, if not even if it will lead to brushing the surface
Uneven quality. In the use of metal materials, the production or storage of the environment whether there is oil, if there is oil, then it will be very impact
Bonding effect. It is also to be checked from the silica gel seal you use, which is contaminated, such as dust
Oil, etc., the adhesive material is contaminated the same effect on the bonding quality.
