Resin: PVC ka kakaretso e sebelisa resin ea mofuta oa 8, e nang le lebelo le potlakileng la gelation nakong ea ts'ebetso, mocheso o batlang o le tlase oa ts'ebetso, boleng bo tsitsitseng ba sehlahisoa, le taolo e bonolo ea sekhahla.Lilemong tsa morao tjena, baetsi ba bangata ba fetohile ho mofuta oa 5 resin.
Stabilizer: Khetho ea stabilizer, ho nahanoa ka ts'ireletso ea tikoloho le phello e ntle ea "rare earth stabilizer" e ratoang, empa ka lebaka la theko e batlang e phahame, e sa khothaletsoang, bokamoso bo nang le litlhoko tsa ts'ireletso ea tikoloho ho eketseha, 'maraka o sa tloaelehang oa lefatše o tla kenya letsoho. litebello tse khanyang.Calcium zinc stabilizer e na le bothata ba ho chesa zinki mme phello ea botsitso e fokola hanyane mme palo e nyane.Hona joale, ka ho fetisisa sebelisoa kapa etella letsoai stabilizer, foam boto ka lebaka la hlobo sefapano-karolo e pharaletseng, phallo kanaleng e telele le mosehla foam decomposition mocheso tlhahiso, stabilizer e hlokehang ho ba le lintho tse ngata etella pele le phello e ntle botsitso, ho seng joalo. sehlahisoa se na le mathata a fapaneng.
Moemeli oa ho foka: ho khethoa ha moemeli ea fokang, ho foka moemeli oa AC ts'ebetsong ea ho bola ho lokolla mocheso o mongata, ho bonolo ho isa bohareng ba karolo e mosehla, e hlokang palo e itseng ea moemeli o mosoeu, ho bola ho phetha karolo ea ho monya ho feteletseng. matla a mocheso, a hloka hore palo ea moemeli ea fokang e be khōlō, e le ho finyella foaming e tšoanang ntle le masoba a maholo a bubble.
Regulator: Foaming regulator, ho theosa le lilemo tsa lipatlisiso le nts'etsopele le ntlafatso, thekenoloji ea ts'ebetso ea taolo ea foam ACR e ntse e hola le ho feta, 'me boleng ba ts'ebetso bo ntse bo tsitsa le ho feta.Ho ea ka botenya ba foaming boto, lakane lokela ho plasticized ka potlako, 'me boto teteaneng e lokela ho plasticized butle tharollo e matla foaming regulator.
Lisebelisoa: Ho khethoa ha mafura ho latela molao-motheo oa ho tlotsa pele, bohareng le morao-rao, e le hore lisebelisoa li sirelelitsoe ke mafura ka mekhahlelo eohle, 'me li khomarele tlhahiso e tsitsitseng ea nako e telele ntle le ho silafala.
Lisebelisoa tse thusang tse foaming: E le ho ntlafatsa boleng ba foam le sebopeho sa foam, ho ka eketsoa lisebelisoa tse nyane tse nang le foaming zinc oxide tlhahisong, 'me ho ka eketsoa palo e nyane ea silicate ea aluminium molemong oa ho fokotsa pula.
Li-pigments: E le ho finyella phello e ntle haholoanyane, titanium dioxide le li-fluorescent whitening agents li ka eketsoa, 'me li-antioxidants le lisebelisoa tsa ultraviolet li ka eketsoa ho ntlafatsa ho hanyetsa boemo ba leholimo.
Filler: Khetho ea khanya ea calcium carbonate e ka ba, ntle le tšebeliso ea khalsiamo e sebetsang, khetho ea palo e phahameng ea mesh.
Thermoplastic high-molecular polymer e entsoeng ke ho fanyeha polymerization ea vinyl chloride monomer.Thepa ea molek'hule :- (CH2 – CHCl) n – (N: tekanyo ea polymerization, N= 590 ~ 1500).Ke thepa e tala ka ho fetisisa e sebelisoang tlhahisong ea polasetiki.E na le botsitso bo botle ba lik'hemik'hale, ho hanyetsa kutu le ho hanyetsa metsi.
