PVC Foam board impahla eluhlaza
I-resin: I-PVC ngokuvamile isebenzisa uhlobo 8 lwe-resin, enejubane elisheshayo lokugezela ngesikhathi sokucutshungulwa, izinga lokushisa eliphansi lokucubungula, ikhwalithi yomkhiqizo ezinzile, nokulawula ukuminyana okulula.Eminyakeni yamuva, abakhiqizi abaningi baye bashintsha ukuze bathayiphe i-5 resin.
I-Stabilizer: Ukukhethwa kwe-stabilizer, kucatshangelwa ukuvikelwa kwemvelo kanye nomphumela omuhle we-stabilizer yomhlaba ethandwayo ethandwayo, kodwa ngenxa yentengo ephakeme kakhulu, engakhuthazwa, ikusasa elinezidingo zokuvikela imvelo ukuze likhule, imakethe ye-stabilizer yomhlaba engavamile izongenisa. amathemba aqhakazile.I-calcium zinc stabilizer inenkinga yokushiswa kwe-zinc futhi umphumela wokuzinza umpofu kancane futhi inani lincane.Njengamanje, i-stabilizer kasawoti esetshenziswa kakhulu noma eholayo, ibhodi legwebu ngenxa ye-mold cross-section libanzi, isiteshi sokugeleza side futhi ukukhiqizwa kokushisa kwegwebu eliphuzi, i-stabilizer iyadingeka ukuba ibe nokuqukethwe okuphezulu kokuhola kanye nomphumela omuhle wokuzinza, ngaphandle kwalokho. umkhiqizo uthambekele ezinkingeni ezihlukahlukene.
I-ejenti evuthelayo: ukukhethwa kwe-ejenti evuthelayo, i-ejenti efuthayo ye-AC enqubweni yokubola ikhulula ukushisa okuningi, kulula ukuholela phakathi nendawo ephuzi, okudinga inani elithile le-ejenti ephephethayo emhlophe, ukubola kudlala indima yokumunca ngokweqile. amandla okushisa, adinga inani le-ejenti evuthelayo libe likhulu, ukuze kuzuzwe ukugwetshwa okufanayo ngaphandle kwezimbobo ezinkulu zebhamuza.
Isilawuli: isilawuli esinegwebu, ngeminyaka yocwaningo kanye nentuthuko kanye nokwenza ngcono, ubuchwepheshe benqubo yesilawuli esinegwebu i-ACR buya ngokuya buvuthwa, futhi ikhwalithi yokusebenza iya izinza kakhulu.Ngokusho ukushuba ibhodi amagwebu, ishidi kufanele plasticized fast, futhi ibhodi awugqinsi kufanele plasticized isisombululo slow eqinile ogwebu isilawuli.
Izinto zokugcoba: Ukukhethwa kwezithambisi kulandela isimiso sokugcotshwa kwangaphambi kwesikhathi, okuphakathi kanye nangemuva kwesikhathi, ukuze izinto zivikelwe izinto zokugcoba kuzo zonke izigaba, futhi zibambelele ekukhiqizeni okuzinzile kwesikhathi eside ngaphandle kokungcola.
Izinsiza ezinegwebu: Ukuze kuthuthukiswe ikhwalithi enegwebu kanye nesakhiwo segwebu, inani elincane lezinto ezisizayo ezinegwebu zingangezwa ekukhiqizeni, futhi inani elincane le-aluminium silicate lingangezwa ukuze kuncishiswe imvula.
Izingulube: Ukuze kuzuzwe umphumela omuhle kakhulu, i-titanium dioxide kanye nama-fluorescent whitening agents anganezelwa, futhi ama-antioxidants kanye nama-absorber ultraviolet anganezelwa ukuthuthukisa ukumelana nesimo sezulu.
Isigcwalisi: Ukukhethwa kwe-calcium carbonate ekhanyayo kungaba, ngaphandle kokusebenzisa i-calcium esebenzayo, ukukhethwa kwenombolo ye-mesh ephezulu.
I-thermoplastic high-molecular polymer eyenziwe yi-suspension polymerization ye-vinyl chloride monomer.I-molecular formula :- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500).Yimpahla eluhlaza esetshenziswa kabanzi ekukhiqizeni ipulasitiki.Inokuqina okuhle kwamakhemikhali, ukumelana nokugqwala nokumelana namanzi.
