Applied in BOPS紅好

BOPP,BOPET This kind of pla雪吧stic products are cha煙藍racterized by high tr議從ansparency, high precision and re著化latively high molding temperat光水ure, such as BOPET P很醫ET packaging tape and PET風下 film. The special mesh changer has t水綠he following characteristics:

1) It has a "special position" exhaus筆藍t mechanism and a flow channel.拿上 It can clean up the gas in the n森睡ew net when changing t身車he net and keep the pressure balance o月音f the net change, and thorou船日ghly solve the prob弟去lem of "bubble".

2) The exhaust position is also the 舊志preheating position o老是f the net block at the s場離ame time. It can be guaranteed that頻就 the net to be change開見d is the same as that of t區市he net being changed, 司鐵thus avoiding the fact tha唱鐵t the low temperature of the new m紙土esh leads to the crys跳那tallization of the 家線melt and the flow becomes用草 poor, and even the crystal po習哥int.

3) The ordinary什黑 mesh changer is a filter (p明睡orous plate) carrier directly in co拿店ntact with the plastic mel吧分t.

The special mesh changer is different:她錯 the filter (perforated plate) an日個d the carrier become a net現工 block as a whole, and it飛民 circulates and moves i音有n one direction, avo畫玩iding the occurrence of the black spo湖舞t impurity, and after 道花changing the net, it can be tak店喝en down and cleaned together.
Clean mesh reinstalled with a new filte吧厭r net has excellent fluidity. I歌舞n order to maintain the stabil服外ity of the mechanical rigid seal聽筆 of the mesh cha樹跳nger, the steel used is more wea讀裡r-resistant and heat-re舊說sistant than that of the norm分票al mesh changer, and the runner is smo呢水other.
