How to bond the broken rubber sealant strip? If the rubber sealing strip breaks, it can be repaired with adhesive, but the sealing strip needs special adhesive. It is very simple to repair the crack of the sealing strip. Of course, if the sealing strip is seriously damaged or aging, the better way is to replace (replace) the sealing strip to save energy.
Rubber sealant strips are usually made of rubber materials with excellent aging resistance, such as butadiene rubber, silicone rubber, natural rubber butadiene styrene rubber and rubber plastic mixtures. According to the use position, it can be divided into three categories: Marine sealing strip, automobile sealing strip, mechanical sealing strip and door and window sealing strip. Wherein, the mechanical sealing strip comprises a container sealing strip and a cabinet sealing strip.
The rubber sealant strip is usually in the range of - 50? 70 ℃. The process is divided into dense rubber belt, sponge rubber belt, two composite rubber belts and three composite sealing belts. Different cross-sectional structures can be designed according to their use positions and conditions. Considering the requirements of aging resistance, oil resistance, heat resistance, fire resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance and flame retardancy.
The production and vulcanization methods of rubber sealant strips usually adopt the extrusion continuous vulcanization method of rubber extruder, the vulcanization method of extrusion molding vulcanization tank or the molding vulcanization method. The surface of the rubber sealing strip thus made is very flat. If you look at its surface, you will find that its surface has a very uniform foam density layer and also has good resilience. Among them, it has good sealing performance, high temperature and weather resistance, aging resistance, impact resistance and water resistance. If the back tape is self-adhesive, some rubber sealing strips can also bond smooth surface materials.
