1. The use of modified silicone oil: on the one hand, it can inhibit the yellowing of the silicone rubber after vulcanization in the second stage; on the other hand, it can increase the vulcanization ......
2020-03-05For high-temperature vulcanized silicone rubber, two-stage vulcanization is usually required to remove the decomposition residues of the peroxide, while further crosslinking the silicone rubber to obt......
2020-03-05Mixing is one of the most important components in the rubber processing process. Mixing can be performed by separate mixers and mixers. The mixer mixing is also divided into high temperature and low t......
2020-03-04A product obtained without strict technological processes, even if the inferiority of the product can not be detected on the spot, it will always be built on a quicksand like a pagoda, I wonder if it ......
2020-03-04As a rubber product manufacturer, there are often questions: rubber formula, technology and other technologies are definitely important, but how important is it, how much gold does he have, and can a ......
2020-03-04If there are large particles or large rubber in the sealant, it is a control problem in the production process, which can be solved by strengthening management and strengthening control. If there a......
2020-03-04The surface drying time of the weather-resistant rubber is 30-40 minutes, which is not short for normal construction, but the surface drying will be faster when the construction environment changes gr......
2020-03-04In two words, explain this phenomenon "the diversity of construction materials, the instability of sealants". First of all, the diversity of construction materials: there are many types of construc......
2020-03-03Ketone oxime transparent glue (including light-colored glue) will turn yellow to varying degrees after curing for about twenty days, and the yellowing tendency will increase with the increase of time.......
2020-03-03This kind of situation occurs more frequently during vertical seam sizing. The reason for this analysis should be that the initial wetting time of the glue is slower on the surface of the substrate, t......
2020-03-03After the real rubber strip is cured, there are very few intermediate cracks. Because there are too few cases, it is not very clear about some objective conditions, so it is impossible to accurately d......
2020-03-03Firstly, the objective conditions of sizing have a great influence on the deep curing speed. Such as the construction environment, temperature, and humidity have a relatively large impact on the curin......
2020-03-03This situation is mainly caused by the following two reasons. First, the storage temperature is too low: if the acid glue (especially low-grade glue) is stored at a lower temperature, a lot of bubb......
2020-03-02There are two reasons for this problem, which are related to both glue and bottle. First, the reason for the glue. Except for a few high-end rubbers, other acid rubbers on the market now add a cert......
2020-03-02The common places where glass glue is used in home furnishings are: dumb mouths on the back of wooden lines, sanitary ware, toilets, toilet mirrors, gaps between sinks and walls, gaps between wooden d......
