HT144HE＝塑胶原料Long term supply of
PA66 has higher melting point in polyamide material. In product design, a PA66 shrinkage between 1%~2%.
Now on the market circulation of many disposable nozzle by modification of the same material can reach the original material, but the price is relatively cheaper than raw materials, so as to give our customers a lot of cost saving.

In order to improve the adhesion of the coating on the plastic surface and improve the appearance of the plastic, the surface of the
ABS must be pretreated before coating. (1) the internal stress is easy to form when the plastic ABS is formed, and the stress concentration is easy to crack. The annealing treatment or the whole surface treatment can be used to eliminate stress. The annealing treatment is to heat the ABS plastic parts under the hot deformation temperature, that is, 60 DEG C, the insulation 2h. In order to reduce equipment investment, the whole process can be used to improve the surface condition. The formula and process of the whole process are listed in table 1. Table 1 the entire surface treatment project formulation and process parameters / 1 / 3 / C water temperature at room temperature the processing time of /mi15 - 20 (2) in addition to oil ABS plastic surface often Zhanyou oil, hand sweat and release agent, it will make the paint poor adhesion, coating cracking, blistering and shedding. Degreasing treatment should be carried out before painting. ABS plastic parts are usually cleaned with gasoline or alcohol, and then chemical degreasing. The process formula is listed in table 2. Table 2 degreasing process formula and process parameters of sodium hydroxide (S/L) Project 50 ~ 70 sodium phosphate (S/L) 20 ~ 30 sodium carbonate (S/L) from 10 to 20 surfactant (S/L) 5 ~ 10 / 50 ~ 60 DEG C temperature processing time /min10 to thoroughly clean the residual lye surface chemical oil 15 Zui, and pure water after the clean, dry or drying. (3) in addition to electricity and dust plastic products are insulators, surface resistance is generally around 1013, easy to produce static electricity. After being charged, it is easy to absorb the fine dust in the air and attach to the surface. It is very difficult to remove the dust by electrostatic adsorption. It is better to use high pressure ionization air flow to remove dust.
