Lo mbhobho wePVC-O we-UPVC ovelisa ukwenza umatshini usebenzise ubuchwephesha obutsha ukwenza imibhobho yeplastiki. Ngeteknoloji ekhethekileyo yokwelula i-biaxial, inokunciphisa kakhulu iindleko zempahla yokuvelisa umbhobho, ngaphezu kwe-70%. Iya ithandeka ngakumbi ngoku kule mihla.
Imodeli/idatha Umbhobho ubukhulu Extruder imodeli Speed Max umthamo
FP250 90-250mm LSZ65 1.5-8m/min 300kg/h
FP315 110-315mm LSZ75 0.5-5m/min 500kg/h
FP630 400-630mm LSZ92 0.1-2m/min 800kg/h
Umbhobho wePVC-O luhlobo lwamva nje lwenguquko yombhobho wePVC. Ngokusebenzisa inkqubo yokuqhelaniswa ekhethekileyo (iteknoloji yokwelula i-biaxial), ukolula kunye nokwelula kwe-radial, ukwenzela ukuba iimolekyuli zePVC ze-long-chain kumbhobho biaxially zicwangciswe ukuze kufumaneke amandla aphezulu, ukuqina okuphezulu, ukuxhathisa impembelelo ephezulu, ukumelana nokuqhekeka kwePVC entsha. umbhobho.
Inkqubo yokwelula yokuqhelanisa izinto zepolymer yinkqubo yeemolekyuli ezilungiselelwe ukusuka kwi-disordered ukuya kwi-odolo phantsi kwesenzo samandla angaphandle phantsi kwemeko yeqondo lokushisa phakathi kweqondo lokushisa lokutshintsha kweglasi kunye nobushushu obunyibilikayo (ngokuqhelekileyo kufuphi nendawo yokuthambisa). I-Biaxial stretching yinkqubo apho i-biaxial stretching yinkqubo apho i-biaxial yoluliwe ukwenza amandla e-perpendicular ukuya kwindawo eyoluliweyo ye-biaxial stretching ebekwe phezulu kumandla ecala lendawo eyoluliweyo, ngaloo ndlela inyusa amandla ezinto eziya kwicala lendlela eyoluliweyo. umphezulu.
Thelekisa imibhobho yePVC eqhelekileyo, ubukhulu bodonga lombhobho lwePVC-O lubhityile kakhulu, kodwa lunokunyamezela uxinzelelo oluphezulu. Ngomatshini wokwenza umbhobho wePVC-O, umxhasi unokonga kakhulu iindleko zezinto eziphathekayo.
Umbhobho we-PVC-O ngumbhobho oveliswa yinkqubo yokwelula i-bidirectional.Ukwenziwa kwezinto eziluhlaza zombhobho ngokusisiseko kufana nombhobho oqhelekileyo wePVC-U. Ukusebenza kombhobho oveliswa yile nkqubo kuphuculwe kakhulu xa kuthelekiswa nombhobho wePVC-U, ukuxhathisa kwempembelelo yombhobho kuphuculwe malunga namaxesha ama-4, ukuqina kwe-stl kugcinwe kwi-minus -20" C, kunye nobukhulu bodonga lwePVC. -U umbhobho uncitshiswe nge-alf phantsi koxinzelelo olufanayo malunga ne-47% yezinto eziluhlaza zigcinwa, kwaye udonga oluncinci luthetha ukuba imibhobho yokuhambisa amanzi inamandla, imibhobho ilula kwaye ikulungele ukuyifaka, kunye nokuthutha. ixabiso liphantsi.
