FAQ
Zeziphi izinto ezisebenza kakuhle nge-parallel twin screw barrel?
I-high-grade alloy steel kunye ne-bimetallic liners iphatha iiplastiki ezininzi, kuquka i-PVC, i-PE, kunye ne-PP. Ezi zixhobo zixhathisa ukugqoka kunye nokubola ngexesha lokusebenza okuqhubekayo.
Kufuneka abasebenzi bahlole kangaphi ukuba i-screw barrel ukuba igugile?
Abasebenzisi kufuneka bahlole i-screw barrel rhoqo kwiinyanga ezintathu ukuya kwezintandathu. Ukutshekishwa rhoqo kunceda ukugcina ukusebenza kunye nokukhusela ixesha lokuphumla elingalindelekanga.
Ngaba inkqubo yombhobho we-screw ehambelanayo inokuphinda isetyenziswe iiplastiki?
Ewe.Izikhonkwane ezingamawele ezinxuseneyoiyakwazi ukucubungula iiplastiki ezisetyenzisiweyo ngokufanelekileyo. Uyilo luqinisekisa ukuxuba ngokucokisekileyo kunye nokunyibilika okuhambelanayo, nokuba nomgangatho wezinto eziguquguqukayo.
