PVC resini, PVC resin ma faʻaopoopoga, PVC resin mo le gaosiga o paipa, PVC SG-5, PVC SG-8, PVS SG-7,

PVC fa'apipi'i palasitika e tele lava ina fa'avaeinaPVC resin ma faʻaopoopogas, lea additives e tusa ai ma le galuega tauave ua vaevaeina i: stabilizer vevela, lubricant, faagasologa modifier, aafiaga modifier, filler, sui matua, colorant ma isi.Aʻo leʻi fuafuaina le faʻatulagaina o le PVC, e tatau ona tatou malamalama muamua i meatotino o le PVC resin ma faʻaopoopoga eseese.

Mea mata ma mea faaopoopo

PVC resini

PVC palasitika fa'amatalaga fa'aigoaina o le resin o le polyvinyl chloride resin (PVC), o le PVC o lo'o faia i le vinyl chloride monomer polymerization polymer, o lona lua na'o le PE, fa'avasega le lona lua.

PVC resin e mafai ona vaevaeina i ituaiga tatala (XS) ma fufusi ituaiga (ⅺ) ona o le dispersants eseese i le polymerization.Ole lapopo'a ole lapopo'a ole 0.1-0.2mm, ole pito i luga e le masani ai, porous, cotton polo, faigofie ona fa'aulu i le plasticizer, lapopo'a lapopo'a o lo'o i lalo ole 0.1mm, tulafono luga, malo, foliga tenisi laulau, e le faigofie ona mitiia le plasticizer, o le fa'aoga nei. o loose type sili atu.

PVC e mafai ona vaevaeina i vasega masani (PVC oona) ma le soifua maloloina vasega '(le-o'ona PVC).Manaoga o le soifua maloloina o le vinyl chloride (VC) mea e maualalo ifo i lo le LOXL0-6, e mafai ona faʻaaogaina i meaʻai ma vailaʻau.E ese le faiga faʻapipiʻi, e mafai ona vaevaeina PVC i le PVC faʻamalolo ma le PVC emulsion.E tusa ai ma le tulaga faaleatunuu GB / T5761-93 "auala taofi lautele polyvinyl chloride resin asiasiga tulaga", auala taofia PVC ua vaevaeina i PVC-SGL i PVC-SG8JK resin, o le laʻititi le numera, o le maualuga o le tikeri o le polymerization, o le sili atu. le mamafa mole, o le maualuga o le malosi, ae sili atu le faigata o le tafe liusuavai, faagasologa e sili atu ona faigata.Filifiliga faʻapitoa, fai mea vaivai, le faʻaaogaina lautele o PVC-SGL, PVC-SG2, PVC-SG3 ituaiga, e manaʻomia le faʻaopoopoina o se numera tele o plasticizers.Mo se faʻataʻitaʻiga, PVC ata tifaga faʻaaoga SG-2 resin, faʻaopoopo 50 i le 80 vaega o plasticizer.Ma pe a gaosia oloa faigata, aua le faʻaopoopo pe faʻaopopo le plasticizer i se aofaiga laʻititi masani, faʻaaoga PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 o lea.E pei o le PVC paipa malosi faʻaaoga SG-4 resin, palasitika faitotoa ma faamalama talaaga otooto e faaaoga SG-5 resin, pepa manino maaa faaaogaina SG-6 resini, faʻamatalaga malosi foam faʻaaogaina SG-7, SG-8 resin.Ma emulsion PVC fa'apipi'i e masani ona fa'aaogaina mo pa'u faufau, pepa puipui ma pa'u fola ma lofu oloa palasitika.O nisi PVC resin gaosi oloa PVC resin e tusa ai ma le polymerization tikeri (polymerization tikeri o le numera o iunite filifili, polymerization tikeri faatele i le mole mamafa mamafa o le filifili e tutusa ma le mole mamafa mamafa o le polymer) faavasegaina, e pei o Shandong Qilu petrochemical laau lautele gaosiga o PVC resin, fale gaosi oloa mo SK-700;SK – 800;SK – 1000;SK – 1100;SK - 1200, ma isi. O le tikeri tutusa o le polymerization o le SG-5 resin o le 1000 - 1100. O mea faʻaletino ma vailaʻau o le PVC resin vaʻaia le fa.

O le paʻu PVC o se paʻepaʻe paʻepaʻe ma le mamafa o le 1.35 - 1.45 g / cm3 ma le foliga vaaia o le 0.4-0.5 g / cm3.Su'esu'e le lapopo'a o mea e mafai ona vaivai, ma'a'a, mea fa'apalasina lautele 0-5 o mea faigata, 5-25 o oloa semi-malo, sili atu i le 25 o mea vaivai.

PVC o se ituaiga o amorphous, polar polymer, faamaluluina vevela ma liusuavai vevela e maualuga, PVC mama e tatau ona i ai i le 160-210 ~ C plasticizing faagasologa, ona o le sootaga polar i le va o macromolecules ina ia faaalia PVC se faatinoga faigata ma brittle.E le gata i lea, o mole mole PVC o loʻo i ai vaega o le chlorine, pe a oʻo i le 120 ~ C, o le PVC mama o le a amata ona aveese le HCl tali, o le a taʻitaʻia ai le faʻaleagaina o le PVC.O le mea lea, o ituaiga uma o mea faʻaopoopo e tatau ona faʻaopoopoina i le faʻagasologa o suiga o le PVC ma le suiga o aʻafiaga, ina ia mafai ona faʻaaogaina e avea ma mea aoga.

O le PVC resin e masani ona faʻaaogaina mo le gaosiga o ituaiga eseese o ata manifinifi (e pei o ata lolomi i aso uma, ata faʻapipiʻi fale gaosi oloa, ata faʻatoʻaga faʻatoʻaga, ata vevela vevela, ma isi), ituaiga uma o ipu, laupepa, e mafai ona faʻaogaina le laupepa mo mea fa'apipi'i), ituaiga uma o paipa, e pei o le le oona i luga o paipa filo paipa, fa'agogo malamalama, ma isi), ituaiga uma o mea fa'apitoa fa'apitoa, e pei o le faitoto'a, fa'amalama, teuteu ipu, fagu pu'u ga'o (mo cosmetics ma meainu), Uaea, ituaiga uma o mea tui ma paʻu faʻapitoa, paʻu fola, meataalo palasitika, ma isi.

Zibo Junhai Chemical o le uluaʻi ita a Sinopec Qilu, o le PVC faʻailoga autu e pei ona mulimuli mai.
