Boitsebiso ba PP ke eng?
PP e khutsufetse bakeng sa Polypropylene, polymer ea thermoplastic e entsoeng ka polymerisation ea propylene monomer. Joaloka thepa ea bohlokoa ea polasetiki, PP e na le mefuta e mengata ea likopo bophelong ba letsatsi le letsatsi le tlhahiso ea indasteri. Sehloohong sena, re tla sekaseka ka botlalo hore na thepa ea PP ke eng, hammoho le litšobotsi tsa eona, ts'ebeliso le melemo.
Litšobotsi tsa mantlha tsa thepa ea PP
Lisebelisoa tsa PP li na le thepa e ntle ea 'mele le ea lik'hemik'hale. Boima ba eona bo tlaase, bo ka bang 0.9 g/cm³ feela, ke boholo bo tlaase ka ho fetisisa ba polasetiki e tloaelehileng, kahoo e na le boima bo bobebe.PP thepa ea mocheso e hanyetsanang le lik'hemik'hale le eona e ntle haholo, e ka sebelisoa ka mocheso o ka holimo ho 100 ° C ntle le deformation. , 'me boholo ba li-acids, alkalis le metsoako ea lintho tse phelang li na le khanyetso e ntle ea kutu. Ka lebaka la melemo ena, thepa ea PP e fetohile khetho e nepahetseng ea thepa libakeng tse ngata.
Ho hlophisoa le ho fetoloa ha lisebelisoa tsa PP
Lisebelisoa tsa PP li ka aroloa ka mekhahlelo e 'meli e meholo, homopolymer polypropylene le copolymer polypropylene, ho latela sebopeho sa limolek'hule le thepa ea tsona. Homopolymer polypropylene e na le thata e phahameng le matla, e etsa hore e tšoanelehe bakeng sa lihlahisoa tse nang le litlhoko tse phahameng tsa boima, ha polypropylene ea copolymer e na le boima bo betere le matla a ts'usumetso ka lebaka la ho kenngoa ha lihlopha tsa vinyl, 'me hangata e sebelisoa lits'ebetsong tse hlokang ho hanyetsa tšusumetso e ntle.PP e ka boela ea e-ba teng. e ka fetoloa ka ho kenyelletsa likhoele tsa khalase, li-minerale fillers, kapa li-retardants tsa malakabe ho ntlafatsa thepa ea eona ea 'mele le ho hanyetsa mocheso, ho fihlela litlhoko tsa mefuta e mengata e fapaneng. lits'ebetso. PP e ka boela ea fetoloa ka ho eketsa likhoele tsa khalase kapa li-filler tsa liminerale kapa li-retardants tsa malakabe ho ntlafatsa thepa ea eona ea 'mele le ho hanyetsa mocheso ho kopana le mefuta e mengata ea lits'ebetso.
Libaka tsa kopo ea lisebelisoa tsa PP
Lisebelisoa tsa PP li ka fumanoa hohle bophelong, 'me likopo tsa tsona li akaretsa masimo a mangata, ho tloha ho thepa ea ho paka le lihlahisoa tsa ntlo ho ea indastering ea likoloi le lisebelisoa tsa bongaka. Sebakeng sa ho paka, thepa ea PP e sebelisoa haholo ha ho etsoa lijana tsa lijo, likotlolo tsa botlolo tsa seno, lifilimi le lihlahisoa tse ling, tse ratoang hobane ha li na chefo, ha li na tatso ebile li tsamaellana le litekanyetso tsa polokeho ea lijo. Ka lihlahisoa tsa ntlo, thepa ea PP e atisa ho sebelisoa ho etsa mabokose a polokelo, libaskete tsa liaparo, thepa ea ka tlung joalo-joalo. Ka lebaka la mocheso o motle le lik'hemik'hale tse hanyetsanang le lik'hemik'hale, PP e boetse e sebelisoa indastering ea likoloi ho etsa li-bumpers, dashboards le linyeoe tsa betri, joalo-joalo PP e boetse e sebelisoa haholo lefapheng la bongaka, tse kang li-syringe tse lahlehang, libotlolo tsa infusion le lisebelisoa tsa ho buoa.
E Setsoalle le Tikoloho le Moshoelella
Lilemong tsa morao tjena, ha tlhokomeliso ea tikoloho e ntse e eketseha, lisebelisoa tsa PP li fumane tlhokomelo e eketsehileng ka lebaka la ho sebelisoa hape le ho fokotsa tšusumetso ea tikoloho. Lisebelisoa tsa PP li ka sebelisoa hape ka ho sebelisoa hape ka mor'a ho lahloa, ho fokotsa tšilafalo tikolohong. Leha thepa ea PP e sa senyehe, phello ea eona ea tikoloho e ka fokotsoa ka katleho ka taolo ea matlakala ea mahlale le ho e sebelisa hape. Ka hona, thepa ea PP e nkuoa e le thepa ea polasetiki e batlang e le botsoalle ebile e tšoarella.
Kakaretso
Lisebelisoa tsa PP ke lisebelisoa tsa polasetiki tse tenyetsehang tse nang le mefuta e mengata ea lits'ebetso. Boima ba eona bo tlase, ho hanyetsa mocheso, ho hanyetsa lik'hemik'hale le ho sebelisoa hape ho etsa hore e be e 'ngoe ea lisebelisoa tsa bohlokoa indastering ea sejoale-joale le bophelong ba letsatsi le letsatsi. Ka ho utloisisa hore na thepa ea PP ke eng le libaka tsa eona tsa ts'ebeliso, o ka sebelisa melemo ea thepa ena hamolemo ho fana ka khetho e tšepahalang bakeng sa moralo le tlhahiso ea mefuta eohle ea lihlahisoa.
