Polyvinyl chloride (PVC) phala Resin, monga momwe dzinalo likusonyezera, ndikuti utomoniwu umagwiritsidwa ntchito makamaka ngati phala. Anthu nthawi zambiri amagwiritsa ntchito phala lamtunduwu ngati plastisol, yomwe ndi mtundu wapadera wamadzimadzi apulasitiki a PVC osasinthidwa. . Phala resins zambiri anakonza ndi emulsion ndi yaying'ono kuyimitsidwa njira.
Utoto wa polyvinyl chloride umakhala ndi kukula kwa tinthu tating'onoting'ono, ndipo mawonekedwe ake ali ngati talc, osasunthika. Utoto wa polyvinyl chloride paste umasakanizidwa ndi Pulasitiki ndikugwedezeka kuti upangitse kuyimitsidwa kokhazikika, komwe kumapangidwa kukhala PVC phala, kapena PVC plastisol, PVC sol, ndipo munjira imeneyi anthu amagwiritsidwa ntchito pokonza Zomaliza. Popanga phala, ma fillers osiyanasiyana, ma diluents, zowongolera kutentha, zotulutsa thovu ndi zowongolera zowunikira zimawonjezeredwa malinga ndi zosowa za zinthu zosiyanasiyana.
Kukula kwa makampani a PVC phala la utomoni kumapereka mtundu watsopano wazinthu zamadzimadzi zomwe zimakhala zopangidwa ndi polyvinyl chloride pongotenthetsa. Mtundu uwu wa zinthu zamadzimadzi ndizosavuta kukonza, zokhazikika pakuchita, zosavuta kuzilamulira, zosavuta kugwiritsa ntchito, zabwino kwambiri pazogulitsa, zabwino pakukhazikika kwamankhwala, zimakhala ndi mphamvu zamakina, zosavuta kuziyika, etc., kotero zimagwiritsidwa ntchito kwambiri. mu zikopa zopangira, zoseweretsa za vinilu, zizindikiro zofewa, Kupanga zithunzi zamapepala, utoto ndi zokutira, mapulasitiki okhala ndi thovu, ndi zina zambiri.
Katundu:
PVC phala utomoni (PVC) ndi gulu lalikulu la polyvinyl kolorayidi utomoni. Poyerekeza ndi utomoni kuyimitsidwa, ndi kwambiri dispersible ufa. The tinthu kukula osiyanasiyana zambiri 0.1 ~ 2.0μm (kugawa tinthu kukula utomoni kuyimitsidwa nthawi zambiri 20 ~ 200μm. ). PVC phala resin adafufuzidwa pafakitale ya IG Farben ku Germany mu 1931, ndipo kupanga mafakitale kudachitika mu 1937.
M'zaka zapitazi, msika wapadziko lonse wa Pvc Resin wakula mwachangu. Makamaka m'zaka khumi zapitazi, mphamvu zopanga ndi zotulutsa zawonetsa kukula kwakukulu, makamaka ku Asia. Mu 2008, mphamvu yapadziko lonse lapansi yopanga phala la PVC utomoni inali pafupifupi matani 3.742 miliyoni pachaka, ndipo mphamvu zonse zopanga ku Asia zinali pafupifupi matani 918,000, zomwe zimawerengera 24.5% ya mphamvu zonse zopanga. China ndiye dera lomwe likukula mwachangu pamakampani opanga utomoni wa PVC, omwe amapanga pafupifupi 13.4% ya mphamvu zonse zopanga padziko lonse lapansi komanso pafupifupi 57.6% ya mphamvu zonse zopanga ku Asia. Ndiwopanga wamkulu kwambiri ku Asia. Mu 2008, kutulutsa kwapadziko lonse kwa utomoni wa PVC kunali pafupifupi matani 3.09 miliyoni, ndipo ku China kutulutsa matani 380,000, kuwerengera pafupifupi 12.3% yazotulutsa zonse padziko lapansi. Mphamvu zopanga ndi zotulutsa zili pachitatu padziko lonse lapansi.
