I-PVC yokumiswa i-resin yokukhiqiza amapayipi e-PVC nokufakwa
I-PVC ukumiswa resin yokukhiqiza amapayipi e-PVC nokufakwa,
PVC ukumiswa resin ukukhiqiza PVC amapayipi kanye nokufakwa,
Ipayipi le-PVC (ihlukaniswe ipayipi le-PVC-U, ipayipi le-PVC-M kanye nepayipi le-PVC-O) ipayipi le-polyvinyl chloride eliqinile, lenziwe nge-PVC resin ene-stabilizer, i-lubricant kanye nokunye ukubunjwa kwe-extrusion okucindezelayo okushisayo, ingeyokuqala ukuthuthukiswa futhi kusetshenziswe ipulasitiki. ipayipi.
Ipayipi le-PVC-U linokumelana nokugqwala okuqinile, ukubopha okulula, intengo ephansi nokuthungwa kanzima, kodwa ngenxa yokuphuma kwe-PVC-U monomer kanye nezithasiselo, ifaneleka kuphela ohlelweni lokuhlinzeka ngamanzi lapho izinga lokushisa lokuthutha lingeqi ku-45 ° C. Amapayipi epulasitiki asetshenziselwa ukufakwa ku-drainage, emanzini angcolile, amakhemikhali, uketshezi olushisisayo nezipholile, ukudla, uketshezi oluhlanzekile kakhulu, udaka, amagesi, umoya ocindezelwe kanye nezinhlelo ze-vacuum.
Ipayipi le-Pvc-o, igama lesiShayina elithi biaxial oriented polyvinyl chloride, iyindlela yakamuva yokuvela kwepayipi le-PVC, ngokusebenzisa inqubo ekhethekile yokucubungula i-orientation ukuze kwenziwe ipayipi, ipayipi le-PVC-U elikhiqizwa indlela ye-extrusion yokwelula kwe-axial kanye nokwelula kwe-radial, ukuthi ama-molecule amaketango amade e-PVC epayipini ekuhlelweni kwe-biaxial, Ipayipi elisha le-PVC elinamandla amakhulu, ukuqina okuphezulu, ukumelana nomthelela omkhulu kanye nokumelana nokukhathala kutholwe.
Imininingwane yomkhiqizo
I-PVC iza ngezindlela ezimbili eziyisisekelo: eqinile futhi evumelana nezimo.Izinhlobo eziqinile ze-PVC zingasetshenziswa kumapayipi, iminyango kanye nama-Windows.Ingasetshenziswa futhi emabhodleleni, kwezinye izinto ezingezona ezokudla, nasemakhadini asebhange noma obulungu.Ingenziwa futhi ibe umkhiqizo ophelile othambile, owenziwa ube nezimo eziguquguqukayo ngokufaka ama-plasticizers, avame kakhulu ama-phthalates.Kuleli fomu, lingasetshenziswa kumapayipi athambile, ama-cable insulators, isikhumba sokulingisa, izimpawu ezithambile, imikhiqizo e-inflatable, nasezinhlelweni eziningi esikhundleni senjoloba.
I-Polyvinyl chloride ingenziwa nge-ethylene, i-chlorine kanye ne-catalyst ngokusabela esikhundleni.Ngenxa yokumelana nomlilo nokumelana nokushisa, i-PVC isetshenziswa kabanzi kuzo zonke izigaba zokuphila kanye nemikhiqizo ehlukahlukene: Isikhumba socingo, isikhumba se-fiber optical, izicathulo, izikhwama, izikhwama, imihlobiso, izimpawu namabhodi, izimpahla zokuhlobisa izakhiwo, ifenisha, ukulenga. imihlobiso, ama-roller, amapayipi, amathoyizi (njenge-Italian "Rody" jumping horse), izibalo zopopayi, amakhethini eminyango, iminyango egoqayo, izinsiza zezokwelapha, amagilavu, iphepha lokudla, imfashini ethile, njll.
I-resin ye-PVC SG5 ekhiqizwa indlela yokumiswa ilungele ukukhiqizwa kwamapayipi aqinile we-PVC namaphrofayili.

Isicelo
Ukubhobhoza, ipuleti eliqinile elibonisa ngale.Ifilimu kanye namashidi, amarekhodi ezithombe.Imicu ye-PVC, amapulasitiki afuthayo, izinto zokuvikela ugesi:
1) Izinto zokwakha: Amapayipi, amashidi, amafasitela nomnyango.
2) Izinto zokupakisha
3) Izinto zikagesi: Ikhebula, ucingo, itheyiphu, ibhawudi
4) Ifenisha: Hlobisa impahla
5) Okunye: Izinto zemoto, izinto ezisetshenziswayo zezokwelapha
6) Ezokuthutha kanye nesitoreji
4. Iphakheji:
Izikhwama zephepha ezingu-25kg ze-kraft ezifakwe izikhwama ze-PP noma izikhwama ze-1000kg zento
