Dalian showed successful partnerships with world famous chemical materials manufacturers, as several companies sealing, bonding material products in China's only service providers.
Dalian showed the automatic polyurethane sealing glue of production equipment, the introduction of Germany times f industrial computer control system to realize linkage, the precision of multi-dimensional running track at the same time able to accurately control the temperature, pressure, viscosity, proportion of adhesive and curing reaction time, by controlling the precise measuring system, the single, a two-component polyurethane, silicone, such as uniform coating by certain proportion, to ensure the sealing strip good adhesion, resilience, and aesthetics.

Sealing strip of resilience depends on how well the foam glue itself first, some low compression rebound foam glue, when using, compression deformation is serious, at one time it is difficult to rebound, when repeated use can't play a role of sealing.Some materials high compression resilience, compression after springback can almost recover to the prototype, the material is suitable for use in place of withhold seal.Second and density of strip and the uniformity of soaking, bubble hole is too big or too small will affect the resilience, and the size of the bubble hole by the proportion of a two-component glue, the temperature of the glue, glue the mixing effect of features such as the decision.Main influencing factors are as follows:
1, first choose good physical property, reasonable process to adapt to the good glue and glue ratio, dow FT630 glue, for example, mixture ratio based on 6:1 7:1;And high quality coating equipment equipment.
2, under the allowed working temperature of glue, glue, high and low temperature and humidity will affect the elasticity and adhesion of strip.
3, according to different factors such as glue, flow to choose suitable shaker and mixing speed, ensure that under the condition of the technology of mixed evenly, smooth out feet.
4, B, B rubber filter blockage adequacy of raw material.
5, B glue off.
6, gaskets need 24 hours to complete maturation period, maturation can be carried out after finish assembly, can appear otherwise collapse, springback is bad situation, or even fall off in the future, etc.
Factors influencing the sealing strip springback bad? What are those?
