yintoni iPVC eqinile?,
eqinile PVC extrusion, iPVC,
I-PVC eqinile (ekwabizwa ngokuba yiiPVC) yeyesithathu ipholima eveliswa kakhulu.Ngokubhekiselele kwi-extrusions yeplastiki, i-PVC yeyona nto ixhaphakileyo iplastiki eqinile.Ixabiso eliphantsi, ineempawu ezinokuphinda isetyenziswe kwaye iguquguquka kusetyenziso lwangaphakathi nangaphandle.Oku kwenzaeqinile PVC extrusionsa ukhetho oludumileyo kuluhlu olubanzi lwezicelo.I-UPVC imele iPVC engafakwanga plastikhi kwaye imathiriyeli ibonakala ngokuqina nokomelela kwayo.Ikwayiplastiki eguquguqukayo kakhulu, ilungele usetyenziso oluninzi
Iimpawu zePVC eziqinileyo
I-PVC yipolymer enzima enokuthi iphuculwe ngakumbi kusetyenziswa izilungisi zempembelelo.I-PVC extrusions eqinile inokomelela okuqinileyo kweekhemikhali.Oku kuthetha ukuba ityhubhu yePVC eqinileyo inokudityaniswa ngokulula, incamatheliswe kwaye idityaniswe kuyo ngokwayo - ilungele amalungu kwimibhobho.Ukuxhathisa kwayo ekudlekeni kwenza iprofayili ye-PVC ekhutshiweyo, amacandelo kunye ne-trim efanelekileyo kwindawo yangaphandle.I-PVC ineempawu ezilungileyo zokugquma kusetyenziso lombane oluphantsi.Enkosi kwiingenelo zayo ezininzi,eqinile PVC extrusions kunye ne-tubing eqinile ye-PVC isetyenziswe ngempumelelo kuzo zombini iindawo zangaphakathi nangaphandle.
I-PVC extrusions engqongqo esetyenziswayo
I-PVC eqinile isetyenziswa ngokubanzi kulwakhiwo lwemibhobho yamanzi kunye nenkunkuma, iindawo zokugcina amanzi, i-gutters, i-cladding, udonga kunye nokukhusela iminyango kunye neefestile zefestile ngenxa yeempawu zayo ezibalaseleyo zokushisa kunye nokuzinza.Kwizicelo zothutho i-UPVC isetyenziswa ngaphandle kwimizimba yezithuthi, iikharavani kunye nokuhamba ngephenyane, kwaye ngaphakathi ekudaleni ubuhle obukholisayo, kuba ifumaneka ngemibala emininzi kunye nokugqitywa komphezulu.Kwicandelo lokuthengisa indawo yokuthengisa imiboniso, ii-racks zokugcina, i-ticket strips kunye ne-poster grippers zonke ziveliswa kwi-PVC ekhutshiweyo eqinile.
Iquka iplastiki ye-thermo, ukunganyibiliki emanzini, i-petroli kunye notywala, ukudumba okanye ukunyibilikiswa kwi-ether, i-ketone, i-chlorinated aliphatic hydrocarbons, kunye ne-hydrocarbon enevumba elimnandi, ukuxhathisa okuphezulu kwi-corrosion, kunye nepropathi efanelekileyo ye-dielectric.
Isicelo
I-PVC Resin SG-3 Isicelo soku:
1. Iprofayile yePVC
Iiprofayili ziyintsimi yokusetyenziswa kwe-PVC kwilizwe lasekhaya, malunga ne-25% yokusetyenziswa kwe-PVC iyonke, ngokukodwa ukwenza iingcango kunye neefestile kunye nezinto zokulondoloza amandla, kwaye isicelo sabo sisesikhulu kunye nokukhula.
2. Umbhobho wePVC
Imibhobho ye-PVC yeyona mizi-2 inkulu yokusetyenziswa, Ukusetyenziswa yi-20% yomthamo opheleleyo wemveliso kwiKhaya laseTshayina, iPipe yePVC.
3. Ifilimu yePVC
Ifilimu yePVC efayiliweyo yeyesithathu isixa esikhulu sokusetyenziswa, imalunga ne-10% yomthamo wemveliso iyonke.
