Li-resin tsa polypropylene (PP) ke li-polymers tsa thermoplastic, ho bolelang hore li ka etsoa ka mocheso 'me tsa qhibiliha hape ntle le ho lahleheloa ke litšobotsi tsa tsona tsa ka hare. Thermoplastics e fapana ka tsela ena ho tloha ho thermosets, e fetohang ka ho sa feleng ka mor'a ho thatafala. Thermoplastics hangata e sebelisoa hape ka lebaka lena. Li-thermoplastics tse ling li kenyelletsa polyethylene, polyvinyl chloride, polystyrene, polycarbonate, acrylic, acrylonitrile butadiene styrene, nylon, le polytetrafluoroethylene.
Li-resin tsa polypropylene hangata li na le li-polymer tse opaque, tse tlase-tlase tse nang le litšobotsi tse ntle haholo tsa thermoforming le ente. Ha ho bapisoa le li-polymer tse ling, thepa e na le mocheso o batlang o le moqotetsane, o fetoha brittle ka tlase ho -20 ° C 'me ha o sebelisoe mocheso o fetang 120 ° C. E qothisana lehlokoa le polyethylene 'me e ka etsoa pepeneneng bakeng sa lintho tse kang liphutheloana tsa ho bona, athe polyethylene e ka etsoa feela e feto-fetoha, joalo ka lijaneng tsa lebese, mohlala. Polypropylene e ke ke ea ts'oana le ho hlaka ha li-polymers tse kang polycarbonate empa e sebetsa hantle haholo.
Li-polypropylene homopolymers le polypropylene copolymers li etsa boholo ba li-polypropylene formulations kajeno. Homopolymer ke sehlopha sa ts'ebeliso e akaretsang, se nang le propylene monomer e le 'ngoe,' me e sebopeho sa kristale ea semi-crystalline. Ho na le mefuta e fapaneng ea li-copolymers, tseo, ha li bapisoa le homopolymer, li eketsehile bonolo, ho hanyetsa tšusumetso e ntle, ho tšoarella hamolemo le ho tiea, ho ntlafatsa matla a mocheso o tlaase, le ho hanyetsa ho phatloha ho molemo. Kereiti ea tšebeliso e akaretsang ke eona e khothaletsoang bakeng sa ho kopana le lijo le lits'ebetso moo ho thatafalang ho leng bohlokoa. Metsoako e meng ea li-co- le homopolymers e fella ka lisebelisoa tse nang le matla a matla a matla (PP impact copolymer); kapa, e kopantsoe le ethylene le butane, thepa e phahameng ea ho tiisa filimi (PP terpolymer); kapa thepa e ntlafetseng ea mechine e kang ho qhibiliha matla le ho atolosa (PP HMS). Polypropylene e fumaneha e le foam e atolositsoeng, e tlase-tlase, e koalehileng (EPP).
Thempereichara e tlaase ea polypropylene e etsa hore ho be thata ho sebetsa ka mochine 'me ho se ho entsoe ho fokolang ho hlahisa likhoele tse loketseng khatiso ea 3D. Leha ho le joalo, viscosity ea eona e tlase mochesong oa ho qhibiliha e etsa hore e tšoanelehe hantle bakeng sa lits'ebetso tsa extrusion le ho bopa, ho kenyeletsoa ho bopa ho otla, ho etsa compression, le rotomolding, mohlala.
Ho fapana le li-thermoplastics tse ngata, polypropylene ha e amohele mongobo habonolo, 'me tlas'a maemo a tloaelehileng hangata e ka bōptjoa ntle le ho qala ho omisoa.

Tšebeliso e ka sehloohong ea propylene e ka aroloa ka mekhahlelo e mehlano: ho bōpa ente ea PP, setšoantšo sa PP, fiber ea PP, filimi ea PP, pipe ea PP.
1. Ho bopa ente ea PP
Plastiki ea PP e sebelisoa haholo ka lisebelisoa tse nyane tsa ntlo, libapalisoa, mechini ea ho hlatsoa, likarolo tsa koloi joalo-joalo.
2. PP terata setšoantšo
Motako oa terata oa polypropylene o sebelisoa haholo lihlahisoa tse lohiloeng ka polasetiki, ts'ebeliso ea letsatsi le letsatsi ea mekotla ea lijana, mekotla e lohiloeng, mekotla ea lijo le mekotla e pepeneneng ke lihlahisoa tsa lisebelisoa tsa terata tsa PP.
3. PP filimi
Filimi ea polypropylene ka kakaretso e arotsoe ka filimi ea BOPP, filimi ea CPP, filimi ea IPP, filimi ea PP e sebelisoa haholo ho paka lijo.
4. PP fiber
Polypropylene fiber ke mofuta oa fiber e entsoeng ka polypropylene ka ho qhibiliha ho ohia. Haholo-holo sebelisoa ka mokhabiso, liaparo le masimo a mang, ho tloha ho kenngwa tshebetsong ha pholisi ea bana ba babeli ka 2011, ho theosa le noka metsi a hlakola, maleiri le lihlahisoa tse ling tsa bo-'mè le masea surge, faeba malapeng thepa phepelo khaello phenomenon.
5. PP pipe
Ka lebaka la khanyetso e se nang chefo le mocheso o phahameng oa polypropylene, thepa ea phala ea PP e sebelisoa haholo phepelong ea metsi le sistimi ea ho futhumatsa, ha e bapisoa le phala ea PE, boima ba phala ea PP bo bobebe, lipalangoang tse bonolo, mme ts'ebetso ea ts'ireletso ea tikoloho e betere, e ka sebelisoa hape. .
