Polyvinyl chloride ke e 'ngoe ea lipolasetiki tse hlano tse kholo ka kakaretso lefatšeng.Ka lebaka la theko ea eona e tlase ea tlhahiso ha e bapisoa le polyethylene le litšepe tse ling, le ts'ebetso ea eona e ntle ea ts'ebetso le thepa ea 'mele le ea lik'hemik'hale ea lihlahisoa, e ka fihlela litlhoko tsa ho itokisetsa ka thata ho bonolo, elastic, fiber, coating le thepa e meng,' me e sebelisoa haholo. mafapheng a fapaneng a kang indasteri, temo le kaho.Mokhoa oa ho tsosolosa le ho sebelisa litšila tsa polyvinyl chloride ke tsa bohlokoa haholo.
1.Nchafatso
Ntlha ea pele, ho tsosolosoa ka ho toba ho ka etsoa.Ho tsosolosoa ka ho toba ha lipolasetiki tsa litšila ho bolela ho sebetsa ka ho toba le ho bōptjoa ha lipolasetiki tsa litšila ka ho hloekisa, ho senya, le ho etsa polasetiki ntle le tlhokahalo ea liphetoho tse fapa-fapaneng, kapa ho lokisa le ho bōptjoa ha lihlahisoa ka granulation.Ho phaella moo, e ka boela ea fetoloa le ho tsosolosoa.Ho fetoloa le ho nchafatsoa ha li-plastiki tsa khale ho bolela phetoho ea 'mele le ea lik'hemik'hale ea lipolasetiki tse tsosolositsoeng pele li sebetsa le ho etsoa.Phetoho e ka aroloa ka phetoho ea 'mele le phetoho ea lik'hemik'hale.Ho tlatsa, motsoako oa fiber, le ho kopanya ho thatafatsa ke mokhoa o ka sehloohong oa phetoho ea 'mele ea PVC.Phetoho ea ho tlatsa e bua ka mokhoa oa phetoho oa ho kopanya ka mokhoa o ts'oanang li-modifiers tsa ho tlatsa li-particulate tse nang le modulus e phahameng haholo ho li-polymers.Fiber composite reinforcement phetoho e bolela mokhoa oa ho fetola oa ho eketsa modulus e phahameng le likhoele tse matla tsa tlhaho kapa tsa maiketsetso ho polymer, ka hona ho ntlafatsa haholo thepa ea mochini oa sehlahisoa.Phetoho ea lik'hemik'hale ea PVC e finyelloa ka ho fetola sebopeho sa PVC ka lik'hemik'hale tse itseng tsa lik'hemik'hale.
2.Ho tlosoa le ho sebelisoa ha hydrogen chloride
PVC e na le hoo e ka bang 59% ea chlorine.Ho fapana le li-polymer tse ling tsa carbon chain, ketane ea lekala ea PVC e robeha pele ho ketane e kholo nakong ea ho phunyeha, ho hlahisa khase e ngata ea hydrogen chloride, e tla senya thepa, e chefo ea Catalyst chefo, 'me e ama boleng ba lihlahisoa tse senyang.Ka hona, phekolo ea ho tlosoa ha hydrogen chloride e lokela ho etsoa nakong ea ho phunyeha ha PVC.
3.Ho chesa PVC ho sebelisa mocheso le khase ea chlorine
Bakeng sa litšila tsa polasetiki tse nang le PVC, tšobotsi ea ho hlahisa mocheso o phahameng hangata e sebelisoa ho li kopanya le litšila tse fapaneng tse tukang le ho hlahisa mafura a tiileng a nang le boholo bo lekanang.Sena ha se nolofatse feela polokelo le lipalangoang, empa hape se nka sebaka sa mafura a sebelisoang ho li-boilers tse tukang mashala le li-kilns tsa indasteri, le ho hlapolla chlorine ho ntlafatsa ts'ebetso ea mocheso.
