- 1.PVC resin powder
Yeyona imathiriyeli ekrwada ephambili, isiseko sezinto ezinogwebu, ukuvelisa i-PVC enogwebu ishidi ngokubanzi yamkela iModel SG-8 PVC resin.Xa kusetyenzwa, isantya gelatinization ngokukhawuleza, iqondo lobushushu processing liphantsi ngokwentelekiso, umgangatho imveliso uzinzile, kwaye ukuxinana kulula ukulawula.Ukuze kuphuculwe umgangatho wemveliso kunye nokulawula ngokungqongqo ukuguquguquka kobuninzi bemveliso kunye nobukhulu, i-SG-8 PVC resin isoloko isetyenziselwa ukuveliswa kwe-foam yamahhala kunye ne-Celuka foam PVC sheets.
- 2.PVC ukuzinzisa
Ukuze kufakwe iplastiki ngokupheleleyo izinto ngexesha lenkqubo yebhodi ye-PVC ye-foam, izinto eziphathekayo zihlala kubushushu obuphezulu.Ukongeza, i-ejenti yogwebu iphinda ivelise ubushushu bokubola kwinkqubo yokubola.Ezi zinto zifuna ukuba i-stabilizer ibe nokuzinza okwaneleyo kwe-thermal ukuqinisekisa umgangatho weemveliso kunye nemveliso ezinzileyo yexesha elide. - 3.Ugwebu lomlawuli
Yenziwe nge-methyl methacrylate, i-ethyl acrylate, i-butyl acrylate, kunye ne-styrene.Isakhiwo sayo semolekyuli sisisiseko seqokobhe.Njengoncedo lokucubungula kwinkqubo yokuqulunqa, inokunciphisa ngokufanelekileyo ubushushu beplastiki, ikhuthaze impembelelo yeplastiki, iphucule ukusebenza kakuhle kweplastiki, iphucule amandla anyibilikayo, inciphise ukunyibilika kwenyibilika, ithintele ukuqhekeka, kwaye iphucule kakhulu ukuguda komphezulu weemveliso. .Umgaqo wokhetho wesilawuli sogwebu ubandakanya isantya seplastiki, amandla okunyibilika, kunye nokunyibilika kwamanzi.Ngenxa yeemeko ezahlukeneyo zenkqubo, iimodeli zokulawula ezinogwebu kufuneka zikhethwe ngokweempawu zepropathi ezahlukahlukeneyo, njengephepha elinegwebu, iphepha elinogwebu elityebileyo, ishidi elinogwebu elibhityileyo, iphepha leplastiki elinogwebu, njl. umgangatho webhodi umphezulu.Ngaphandle koko, kufuneka sikhethe izithambiso ezisemgangathweni zangaphakathi nangaphandle kwaye songeze izizinzi zobushushu ezaneleyo kwifomula. - 4.Iarhente yogwebu
I-agent ekhupha ugwebu yimathiriyeli eyenza into ibe yisakhiwo seseli.Inokwahlulwa ibe yiarhente yogwebu lwekhemikhali, iarhente yogwebu ngokwasemzimbeni, kunye ne-surfactant.Isetyenziswa ikakhulu ukulawula ingxinano kunye nomlinganiselo iibhodi PVC amagwebu. - 5.Ukugcwalisa
Kwinkqubo yefomula, idosi eqhelekileyo ye-calcium carbonate ekhanyayo yi-10 ~ 40 phr.Isigcwalisi asinakusetyenziswa kuphela njenge-ejenti ene-nucleating ephuphumayo kodwa sikwanciphisa iindleko zezinto eziphathekayo.Nangona kunjalo, idosi egqithisileyo yokukhanya kwe-calcium carbonate iya kwenza ukufana kweeseli kube kubi ngakumbi, emva koko kuchaphazele imbonakalo kunye nomgangatho wemveliso.Ekugqibeleni yenza ingxinano yemveliso kunzima ukuyilawula, inyusa ixabiso elipheleleyo, kwaye inciphisa ubulukhuni bemveliso. - 6.Ibala
Isetyenziselwa ukufaka imibala ebhodini, ikakhulu emhlophe, ebomvu, etyheli, eluhlaza okwesibhakabhaka, eluhlaza, emnyama, engwevu, njl.
