PP (polypropylene) ke thepa e tloaelehileng ea polasetiki e nang le mocheso o motle oa ho hanyetsa, lik'hemik'hale tse hanyetsanang le lik'hemik'hale tse fokolang. MFPP (modified polypropylene) ke thepa e fetotsoeng ea polypropylene e nang le matla a matla le ho thatafala. Bakeng sa lisebelisoa tsena tse peli, sengoloa sena se tla fana ka kenyelletso e tsebahalang ea mahlale mabapi le mehloli ea lisebelisoa tse tala, lits'ebetso tsa ho lokisa, litšoaneleho le likarolo tsa ts'ebeliso.
1. Mohloli oa lisebelisoa tse tala tsa PP le MFPP Lintho tse tala tsa PP li lokiselitsoe ka polymerizing propylene ka petroleum. Propylene ke sehlahisoa sa petrochemical haholo-holo se fumanoang ka mokhoa oa ho phunyeha libakeng tsa ho hloekisa. MFPP e fetotsoeng ea polypropylene e ntlafatsa ts'ebetso ea eona ka ho eketsa li-modifiers ho PP e tloaelehileng. Li-modifiers tsena e ka ba li-additives, li-filler kapa li-modifiers tse ling tse fetolang sebopeho le sebopeho sa polymer ho e fa thepa e ntle ea 'mele le ea lik'hemik'hale.
2. Mokhoa oa ho itokisa oa PP le MFPP Ho lokisoa ha PP ho finyelloa haholo ka ho arabela ha polymerization. Propylene monomer e entsoe ka polymer ka ketane ea polymer ea bolelele bo itseng ka ketso ea catalyst. Ts'ebetso ena e ka etsahala khafetsa kapa ka linako tse ling, ka mocheso o phahameng le likhatello. Tokisetso ea MFPP e hloka ho kopanya modifier le PP. Ka ho kopanya ho qhibiliha kapa ho kopanya tharollo, mofetoleli o qhalakanngoa ka ho lekana ka har'a matrix a PP, kahoo a ntlafatsa thepa ea PP.
3. Litšobotsi tsa PP le MFPP PP li na le ho hanyetsa mocheso o motle le botsitso ba lik'hemik'hale. Ke polasetiki e bonaletsang e nang le bothata bo itseng le ho tiea. Leha ho le joalo, matla le ho tiea ha PP e tloaelehileng li batla li le tlaase, e leng se lebisang ho kenyelletsoeng ha lisebelisoa tse fetotsoeng tse kang MFPP. MFPP e eketsa liphetoho tse ling ho PP ho etsa hore MFPP e be le matla a betere, ho tiea le ho hanyetsa tšusumetso. Li-modifiers li ka boela tsa fetola mocheso oa mocheso, thepa ea motlakase le ho hanyetsa boemo ba leholimo ba MFPP.
4. Libaka tsa kopo tsa PP le MFPP PP li sebelisoa haholo 'me li atisa ho sebelisoa ka lijaneng, thepa ea ka tlung, lisebelisoa tsa motlakase le lihlahisoa tse ling bophelong ba letsatsi le letsatsi. Ka lebaka la ho hanyetsa mocheso le lik'hemik'hale tsa lik'hemik'hale, PP e boetse e sebelisoa ka liphaephe, lijana, li-valve le lisebelisoa tse ling indastering ea lik'hemik'hale. MFPP e sebelisoa hangata lits'ebetsong tse hlokang matla le boima bo phahameng, joalo ka likarolo tsa koloi, likhase tsa lihlahisoa tsa elektroniki, lisebelisoa tsa moaho, jj.
Qetellong, PP le MFPP ke lisebelisoa tse peli tse tloaelehileng tsa polasetiki. PP e na le litšobotsi tsa ho hanyetsa mocheso, k'hemik'hale ea ho senya lik'hemik'hale le ho fokotseha ha sekhahla, 'me MFPP e fetotse PP motheong ona ho fumana matla a molemo, ho tiea le ho hanyetsa tšusumetso. Lisebelisoa tsena tse peli li bapala karolo ea bohlokoa mafapheng a fapaneng a kopo, ho tlisa boiketlo le nts'etsopele bophelong ba rona le mafapheng a fapaneng a indasteri.
