(1) when annealed plastic ABS is formed, it is easy to form internal stress and easy to crack at the stress concentration after coating. Annealing or surface treatment can be used to eliminate stress. Annealing treatment is to heat the ABS plastic molding parts below the thermal deformation temperature, that is, 60 degrees centigrade, and heat preservation 2H. In order to reduce investment in equipment, the whole surface treatment can be used to improve the surface condition. The formulation and process of the whole surface treatment are listed in Table 1. Table 1 whole surface treatment formula and process parameters / 1 water / 3 temperature / temperature / C room temperature treatment time /mi15 - 20 (2) oil removal ABS plastic parts are often contaminated with oil, hand sweat and demoulding agent, which will make the adhesion of the coating worse, the coating produces cracking, foaming and shedding. Oil removal should be carried out before coating. ABS plastic parts are usually cleaned with gasoline or alcohol and then chemical degreasing. The process formula is listed in Table 2. Table 2 the residual alkaline solution on the surface of the workpiece should be thoroughly cleaned after the process parameters of sodium hydroxide (S/L) sodium 50~70 phosphate (S/L) 20~30 sodium carbonate (S/L) 10~20 surface active agent (S/L) 5~10 temperature / 50~60 treatment time /min10 to 15 chemical oil, and cleaned with pure water Zui, drying or drying. (3) electrical and dust removal plastic products are insulators, and the surface resistance is generally around 1013 ohms, which is easy to generate static electricity. After charged, it is easy to adsorb tiny dust in the air and stick to the surface. It is very difficult to remove dust from electrostatic adsorption by general blowing method. High pressure ionized air flow has good effect in addition to electrostatic precipitator.【通用隨機(jī)圖片】

工藝條件
process conditions
干燥處理：如果加工前材料是密封的，那么就沒有必要干燥。然而，如果儲(chǔ)存容器被打開，那么建議在85℃的熱空氣中干燥處理。如果濕度大于0.2%，還需要進(jìn)行105℃，12小時(shí)的真空干燥。熔化溫度：260~290℃。對(duì)玻璃添加劑的產(chǎn)品為275~280℃。熔化溫度應(yīng)避免高于300℃。 模具溫度：建議80℃。模具溫度將影響結(jié)晶度，而結(jié)晶度將影響產(chǎn)品的物理特性。對(duì)于薄壁塑件，如果使用低于40℃的模具溫度，則塑件的結(jié)晶度將隨著時(shí)間而變化，為了保持塑件的幾何穩(wěn)定性，需要進(jìn)行退火處理。注射壓力：通常在750~1250bar，取決于材料和產(chǎn)品設(shè)計(jì)。
Drying: if the material is sealed before processing, there is no need to dry. However, if the storage container is opened, it is recommended to dry at 85 C hot air. If the humidity is greater than 0.2%, the vacuum drying at 105 C and 12 hours is required.  Melting temperature: 260~290 C. The product of glass additive is 275~280 C. The melting temperature should be avoided above 300 degrees C. Mold temperature: recommended 80 degrees C. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical characteristics of the product. For thin-walled plastic parts, if the mold temperature below 40 degrees is used, the crystallinity of the plastic parts will change with time. In order to maintain the geometric stability of the plastic parts, the annealing process is needed. Injection pressure: usually in 750~1250bar, depending on material and product design.
