Hot sol

Hot sol
  • 详细介绍

With hot sol with high viscosity and high sealing performance and high stability of mobile phone, we can provide such high requirements of the product, the printing technology and integrated precision die-cutting technology, guarantee the fitting precision.

Product selection

A rubber, color requirements should have the difference. If it is then itself has no special requirement to recommend the use of color, yellow hot melt, in general, better than the white viscous yellow glue.
Two, then the surface treatment. Hot melt adhesive on the surface treatment material is then no other adhesive so strict, but then dust, surface oil should also make the appropriate treatment, can better play the role of hot melt adhesive.
Three, operation time. Fast operation is a major characteristic of hot melt adhesive. The operation time of hot melt in 15 seconds, with the wide application of the modern mode of production - line, the operation time of hot melt adhesive requires more and more short, such as bookbinding and speaker manufacturing operation time on the hot melt adhesive required to reach about 5 seconds.
Four, anti temperature. Hot melt adhesive is more sensitive to temperature. The temperature reaches a certain degree, hot melt begin to soften, below a certain temperature, hot melt will become brittle, so choose the temperature change of hot melt adhesive must fully consider the environmental products.
Five, viscosity. Hot melt adhesive is divided into early and late sticky sticky. Only early and late sticky sticky consistency, in order to make the hot melt and then things remain stable. In the production of hot melt process, should ensure that it has antioxidant, anti acid alkali and halogen, plasticizer. By then the different materials, played by hot melt adhesive is also different, therefore, should according to different materials, different choices of hot melt adhesive.

Modified varieties

Modified to improve the performance of hot melt adhesive on the existing varieties of blending and grafting method. For example, stabilizer for preventing oxidation; tackifier to improve bonding strength; reduce the viscosity change of the surface properties of paraffin; various fillers can improve the viscosity, melting point and adhesion strength. Study on various compounding agent type and dosage, and formula optimization to meet the different needs.

new products

Curing hot melt adhesive and hot melt adhesive function is two kinds of new products on the market. The former is the main characteristics, improve the high-temperature properties of hot melt adhesive, improve the softening point to 120 DEG C, so as to expand the scope of its application; functional hot-melt adhesive is for specific occasions, can realize specific functions to meet the needs of a class of all aspects of the need to use glue. Such as water soluble or dispersible hot melt adhesive, hot melt sealant, HMPSA etc.. The following is the description of the hot-melt sealant. It is the first line of a hollow glass sealant with polyisobutylene rubber as the base material of one component, solvent free, no fog, no cure, with permanent plastic. Hot melt butyl sealant to maintain its plastic and sealing in a wide temperature range, and the surface does not crack, not hard. It has good adhesion to glass, Aluminum Alloy, galvanized steel, stainless steel and other materials. Due to its extremely low water vapor transmission rate, which together with flexible sealant to form a superior anti moisture system. Features: good sealing effect, easy quality assurance; without curing period, save the area; an environmentally friendly products, no waste, clean environment; save time, raw materials, personnel, reduce the production cost.
In addition to general EVA, TPR hot melt adhesive, enterprises should also focus on research and development in the West has a large number of applications and the potential application of some high-tech hot melt adhesive products, including: reactive hot melt adhesive, water dispersion type hot melt adhesive, hot melt lining rubber and high grade PA high strength hot melt pressure sensitive adhesive. At the same time, the relevant domestic producers of raw materials should also be aware of the potential development of hot melt adhesive industry, improve the localization rate of raw materials, reduce caused due to a large number of imported raw materials, the loss of foreign exchange.
