Applied in BOPP

 BOPP,BOPET
 This kind of p事黑lastic products are 明中characterized by high件了 transparency, high precision and 少放relatively high molding temp算討erature, such as BOPET PET packaging 到秒tape and PET film. The special m又訊esh changer has the followin就暗g characteristics:

1) it has a "special position" 生紅exhaust mechanism and a 購行flow channel. It can 匠農clean up the gas 還西in the new net when changing th科但e net and keep the pressu雨自re balance of the net白坐 change, and thoroughly 見那solve the problem of "bubble".

2) The exhaust posi妹技tion is also the pr服呢eheating position of the net bloc和技k at the same time. It can be guaran匠嗎teed that the net to b飛老e changed is the s訊雜ame as that of the 綠街net being changed, th刀分us avoiding the fact that the lo照嗎w temperature of the new作門 mesh leads to the cr黃西ystallization of the melt and 了金the flow becomes poor, and ev拿街en the crystal point.

3)The ordinary 男不mesh changer is a filter (porous p我店late) carrier directly in contact 小金with the plastic melt. Because the m讀她esh exchange needs to move場站 back and forth friction, it is easy t開低o produce black spot impur和車ities, filter cleaning 很煙is also ineffective, because 草算the carrier can not be cleaned 西唱directly. The special screen 件區changer is different: the fil民雪ter (perforated plate)醫麗 and the carrier become a net block玩樹 as a whole, and it circulates an雪家d moves in one direction, avoiding the 西通occurrence of the black spot金子 impurity, and after changing th中村e net, it can be taken down and 黃國cleaned together. Clean mesh reinst新聽alled with a new filter net 銀筆has excellent fluidity. In order土新 to maintain the stability of the mec錯頻hanical rigid seal of the screen chan近那ger, the steel used is劇能 more wear-resistant and heat-藍麗resistant than that of the可黑 normal screen 影冷changer, and the runner is smoother.
