Foromong ea PVC ea ho fofisa, e le ho fumana sehlahisoa sa sebopeho sa sele se ts'oanang haholoanyane, se setle, le se ikemetseng, ntle le ho sebelisa li-modifiers tsa foam tse kang lithuso tsa ts'ebetso ea ACR, li-modifiers tsa foam tsa PVC hangata le tsona li sebelisoa foromong. Ka linako tse ling, li-accelerator tsa foam tse kang li-oxide tsa tšepe tse kang zinc oxide le lead oxide, letsoai la asiti ea organic joalo ka zinc stearate, le li-derivatives tsa urea le tsona lia eketsoa (ho lokisa mocheso oa ho bola oa moemeli oa foam). Tekanyo ea molaoli oa foam hangata ke 4% -8% (ho latela kakaretso ea resin), e hlokang ho tsamaellana ka mokhoa o feto-fetohang le li-agent tsa foam (tse kang moemeli oa foam oa AC mosehla, moemeli oa foam oa NC o mosoeu). Tlhahiso ea lipoleiti tse teteaneng e hloka keketseho ea karolo ea moemeli oa foam oa NC oa mocheso o tlase (karolelano e tloaelehileng ea likarolo tse 1.2 tsa NC+0.5 tsa AC) ho qoba ho lokolloa ha khase e kopaneng mohatong oa morao o lebisang ho robeheng ha foam; Taolo ea bongata e hloka ho leka-lekanya tlhahiso ea khase le mocheso oa ho bola.
Taolo ea ho foamela ea PVC ha e le hantle ke polymer ea lotion ea acrylate. E na le litšobotsi tsohle tsa lithuso tsa ho sebetsana le PVC, empa boima ba eona ba limolek'hule bo phahame haholo ho feta ba lithuso tsa ho sebetsana le PVC. Ts'ebetsong ea ho foamela ea PVC, ho eketsa taolo ea ho foamela ea PVC ho ka eketsa matla a ho qhibiliha ha lihlahisoa tsa PVC, ka hona ho thibela ho kopana ha lipululana le ho fumana lihlahisoa tsa foamela ea PVC tse nang le foamela ka ho lekana. Ka nako e ts'oanang, e ka boela ea khothaletsa ho etsoa ha polasetiki ea PVC le ho netefatsa hore ho qhibiliha ho na le phallo e ntle.
Ha o kgetha diphetodi tsa PVC tse foametsang, tlhokomelo e lokela ho lefshwa ho sebedisweng ha diphetodi tse fapaneng tsa foametsang bakeng sa PVC tse nang le maemo a fapaneng a polymerization, jwalo ka PVC-700, PVC-800, le PVC-1000. Dihlahiswa tse fapaneng, tse kang diboto tsa foametsang, diboto tse teteaneng tsa foametsang, diboto tse tshesane tsa foametsang, diboto tsa polasetiki tse nang le foametsang tsa lepolanka, diboto tsa polasetiki tse nang le loto, jj., di hloka tshebediso ya diphetodi tse fapaneng tsa foametsang. Ka lebaka la hore di-agent tsa PVC tse foametsang le tsona ke metswako ya acrylic e nang le thepa ya thuso ya ho sebetsana le tshebetso, tlhokomelo e lokela ho lefshwa ho leka-lekana ha ho tlotsa ka hare le ka ntle ha o di sebedisa. Bangtai Petrochemical Foam Regulator e fihlela ditlhoko tsa hao tse fapaneng bakeng sa dihlahiswa. Bakeng sa dipotso tse ding tsa dihlahiswa mabapi le balaodi ba foametsang ba PVC, ka kopo ikutloe o lokolohile ho re letsetsa!
