Applied in Large Scale Ripple P電冷ipe

BOPP,BOPET This kin個長d of plastic product影會s are characterize中現d by high transparency, high秒美 precision and relative數金ly high molding temperature, suc那工h as BOPET PET packaging ta西呢pe and PET film. The s商時pecial mesh changer h還一as the following characteristics:

1) It has a "special posi動物tion" exhaust mechanis線水m and a flow channel. It ca朋可n clean up the gas in the 通制new net when chan空也ging the net and ke木去ep the pressure balance of the net 通司change, and thoroughly solve the proble什風m of "bubble".

2) The exhaust positi小低on is also the preheatin黃草g position of the net b亮跳lock at the same time. It can時司 be guaranteed that 說做the net to be changed is the same as相月 that of the ne拿內t being changed, t弟行hus avoiding the fac店懂t that the low temperature of the new 東媽mesh leads to the crystall內請ization of the me場議lt and the flow becomes poor, 著錯and even the crystal point.從內

3) The ordinary mesh changer is a f坐工ilter (porous plate) carrier directl討又y in contact with the plastic melt.錢用 Because the mesh exchange needs to m術她ove back and forth friction, it i音水s easy to produce black spot imp行對urities, filter c熱話leaning is also ineffective, beca醫得use the carrier can not be cleaned di員師rectly. The special mesh changer is 物厭different: the filt媽離er (perforated plate) and the carrier b樹電ecome a net block as a w時麗hole, and it circulates and moves一請 in one direction, avoidi了一ng the occurrence 身兒of the black spot impurity, and aft錯的er changing the 山明net, it can be taken down and clea知低ned together. Clean mesh reinstalled 兵鄉with a new filter net has excelle吃小nt fluidity. In order to maintain the s化服tability of the mechanical rigid 黑哥seal of the mesh changer, 他費the steel used is mor是通e wear-resistant and 睡路heat-resistant than that of the n關化ormal mesh changer, and the 章說runner is smoother.
