O LE MATAFAIOI A CPE I PVC LAAU-PLASTIK COMPOSITES
O le faʻaaogaina o le CPE ma le PVC faʻafefiloi palasitika faitotoa ma faʻamalama, o le elasticity, faigata ma le maualalo o le vevela o loʻo faʻaleleia atili, ma o le tau tetee, vevela vevela ma le mautu vailaʻau e lelei.
PVC la'au-palasitika mea tu'ufa'atasiga e tele lava ina aofia ai PVC resin ma fa'atumu.E ala i le tuʻufaʻatasia ma alava laʻau, fetuunaiga o tekinolosi fua, ma le faʻafefiloi o le tino ma le faʻaogaina o le CPE (chlorinated polyethylene) (faʻatasi ai ma le faʻaopoopoga o le aʻafiaga ma le suiga o le aʻafiaga), lea e mafai ona faʻaleleia atili ai le maʻaʻa, malosi, malosi, vevela ma le mumu o le oloa ( i totonu o le faʻatagaina faʻatagaina o manaʻoga faʻaletino, o le maualuga o le chlorine o loʻo i totonu o le CPE, o le sili atu lea o le afi faʻafefeteina), faʻateleina le malosi faʻamalosi, faʻaleleia Le brittleness ma fetolofi teteʻe o le PVC.
O le faiga fa'apipi'i fa'apipi'i o mea fa'apipi'i la'au PVC e matua'i ese lava mai mea fa'apipi'i masani.Talu ai o le vaega autu o le fiber laau o le cellulose, o le cellulose o loʻo i ai se numera tele o vaega hydroxyl, ma o nei vaega hydroxyl o loʻo fausia ai fusi o le hydrogen intermolecular, lea e maua ai e alava laau le malosi polarity ma le faʻafefe vai.I le isi itu, o le tele o mea vevela e le o polar ma hydrophobic, o le mea lea o le fetaui i le va o le lua e matua leaga lava, o le malosi faʻapipiʻi i le atinaʻe e laʻititi, ma o le faʻatumuina o alava laʻau e tele, o lea o le suavai ma le faʻagasologa o le. o le mea e oo ina matitiva , lomi ma extrusion molding avea faigata.O le mea lea, o le faʻaleleia o le faʻatulagaina o mea faʻapipiʻi laupapa-palasitika ua faia se sao lelei i le faʻaleleia atili o le faʻaogaina o le gaosiga ma le faʻatinoga o oloa.
CPE na muamua atiina ae vave o se PVC modifier, ma suia PVC o se tasi o fanua talosaga sili ona taua o le CPE.O loʻo i ai i le CPE mea faʻatumu sili ona lelei, ma o se numera tele o mea faʻapipiʻi eseese e mafai ona faʻaopoopo e faʻaleleia ai ana mea faʻamalosi, faʻamalosi ma faʻaleagaina tumau, ma faʻaitiitia tau.O le faʻaaogaina o le PVC ua faʻaleleia ua faʻaleleia foi.
I le CPE faʻaleleia polokalama ma oloa PVC malosi, faʻatusatusa i isi polymers e pei ole PE ma le PP, o le aʻafiaga o le mumu e matua taua lava.O le tele o oloa PVC malosi e faʻaleleia i le CPE modifier ma le chlorine content o le 36%, ma o lona malosi maualuga o le aʻafiaga e masani lava ona maua e le CPE ma chlorine atoms faʻasalalau faʻasalalau i luga o le filifili autu polyethylene.O le mea lea, e mafai ona faʻaleleia atili lenei faʻaoga i tulaga o le gaioiga, faʻasalalau, ma le malosi o aʻafiaga.
FA'A'OGA O LE CPE I LE UAILI FA'AVAE FA'AVAE, P'U'U, FA'U'U
Talu ai o le mole mole CPE e le o iai ni filifili faʻalua, e lelei le tau o le tau, afi mumu, faʻamautu vevela sili atu nai lo le PVC, tau maualalo ma faʻatinoga lelei.Soluble i hydrocarbons manogi ma halogenated hydrocarbons, e le mafai ona solu i aliphatic hydrocarbons, pala i luga atu o le 170 ° C, ma faamatuu atu hydrogen chloride kasa.O loʻo i ai se fausaga faʻamaʻi mautu, sili ona matua teteʻe, mumu teteʻe, malulu teteʻe, tau teteʻe, free lanu, teteʻe vailaʻau tetee, ozone tetee ma insulation eletise, fetaui lelei ma faagasologa, e mafai ona faʻafefiloi ma PVC, PE, PS ma paʻu i. faaleleia ona uiga faaletino.
