PVC ukunqunyanyiswa resin yokuvelisa imibhobho PVC & nokufakwa
I-PVC yokunqunyanyiswa kweresin yokuvelisa imibhobho yePVC kunye nokufakwa,
I-PVC yokumisa i-resin ukuvelisa imibhobho ye-PVC kunye nokufakelwa,
PVC umbhobho (yahlulwe PVC-U umbhobho, PVC-M umbhobho kunye PVC-O umbhobho) elukhuni polyvinyl chloride umbhobho, yenziwe PVC resin kunye stabilizer, lubricant kunye nezinye eshushu ukubumba extrusion extrusion, yeyokuqala ukuphuhliswa kwaye isetyenziswe iplastiki. umbhobho.
Umbhobho we-PVC-U unokumelana ne-corrosion eyomeleleyo, ukudibanisa okulula, ixabiso eliphantsi kunye nokuthungwa kanzima, kodwa ngenxa ye-seapage ye-PVC-U monomer kunye nezongezo, ilungele kuphela inkqubo yonikezelo lwamanzi apho ubushushu bezothutho aludluli kwi-45 ° C. Imibhobho yePlastiki isetyenziselwa ukufakwa kumanzi amdaka, kumanzi amdaka, kwiikhemikhali, kulwelo lokufudumeza kunye nezipholileyo, ukutya, ulwelo olusulungekileyo, udaka, iigesi, umoya ocinezelweyo kunye neenkqubo zokufunxa.
Umbhobho wePvc-o, igama lesiTshayina elibizwa ngokuba yi-biaxial oriented polyvinyl chloride, yindlela yamva nje yokuguquka kombhobho we-PVC, ngokusebenzisa inkqubo ekhethekileyo yokulungelelanisa ukuvelisa umbhobho, umbhobho we-PVC-U oveliswa ngendlela ye-extrusion yokwelula kwe-axial kunye nokwelula kwe-radial, ngoko. ukuba iimolekyuli ze-PVC ezinde kumbhobho kulungiselelo lwe-biaxial, Umbhobho omtsha we-PVC onamandla amakhulu, ukuqina okuphezulu, ukuxhathisa impembelelo ephezulu kunye nokumelana nokudinwa kwafunyanwa.
Iinkcukacha zemveliso
I-PVC iza ngeendlela ezimbini ezisisiseko: eqinile kwaye ibhetyebhetye.Iifom ezinzima zePVC zingasetyenziswa kwimibhobho, iingcango kunye neWindows.Isenokusetyenziswa kwiibhotile, ezinye izinto ezingezizo ukutya, kunye nebhanki okanye amakhadi obulungu.Isenokwenziwa kwakhona ibe yimveliso ethambileyo egqityiweyo, eyenziwa bhetyebhetye ngakumbi ngokongezwa kweplastiki, idla ngokuba yi-phthalates.Kule fomu, inokusetyenziswa kwimibhobho ethambileyo, i-cable insulators, ukulinganisa kwesikhumba, imiqondiso ethambileyo, iimveliso ezinokuphephetheka, kunye nezicelo ezininzi endaweni yerabha.
I-Polyvinyl chloride inokwenziwa kwi-ethylene, i-chlorine kunye ne-catalyst ngokuphendula ngokutshintsha.Ngenxa yokumelana nomlilo kunye nokumelana nobushushu, i-PVC isetyenziswa ngokubanzi kuzo zonke iinkalo zobomi kunye neemveliso ezahlukeneyo: ulusu lwe-wire, ulusu lwe-fiber optical, izihlangu, izikhwama, iingxowa, izihombiso, iimpawu kunye neebhodi zebhodi, izixhobo zokuhombisa izakhiwo, ifenitshala, ukuxhoma. imihlobiso, iirola, iibhobho, iithoyi (ezifana nehashe elidumileyo elithi "Rody" elitsibayo laseNtaliyane), amanani opopayi, amakhethini ecango, iingcango eziqengqelekayo, izixhobo zonyango ezincedisayo, iiglavu, iphepha lokutya, ifashoni ethile, njl.
I-PVC SG5 resin eveliswa yindlela yokunqunyanyiswa ifanelekile ukuveliswa kwemibhobho yePVC eqinile kunye neeprofayili.
