polypropylene resin hobane e na le ho tiea ho hotle le ho hanyetsa mocheso, 'me ka mor'a hore ho fetoloe ho bolela ho rua, hobane butle-butle sena se nkela lipolasetiki tse ling tsa boenjiniere, tse sebelisoang haholo likoloing, lisebelisoa tsa motlakase le malapa le masimo a mang.

Haholo-holo ka copolymerization polypropylene resin, ka tsoelo-pele ea tshebetso ya tlhahiso le thekenoloji catalyst, e fana ka dihlahiswa ho feta e babatsehang tshebetso akaretsang Empa ka lebaka la tshusumetso ba ne ba fumana hammoho bakeng sa tlhahiso propylene na le mathata a maholo botekgeniki, haholo-holo likarolong tse kang sehlahisoa toughness le rigidity. mokelikeli, hape ha e khone ho tlala ka ho lekaneng libakeng tse ling tsa tlhokeho, ka hona e boetse e hloka motheong oa mofuta o teng oa copolymer polypropylene ka mor'a phetoho, e leng ka ho eketsa nucleating agent elastomer inorganic filler ho finyella lintho tse kang ho tiea ho hoholo.

Ho thatafala ha thepa ea polypropylene e nang le boima bo phahameng le metsi a mangata hangata ho ntlafatsoa ka ho eketsa nucleating agent kapa inorganic filler.Ka tlatsetso ea li-inorganic filler tse kang calcium carbonate, talcum powder, mica, diatomite, joalo-joalo, ho kobeha ha polypropylene resin Matla a flexural le flexural elastic modulus a eketseha butle butle, empa ka nako e ts'oanang, bolelele le matla a ts'usumetso ea polypropylene a tla eketseha. ho fokotseha, 'me' mala le ho fokotseha ha lihlahisoa tsa polypropylene li tla ameha.Ho feta moo, ho eketsoa ha palo e kholo ea li-filler tsa inorganic ho tla ntlafatsa bongata ba lisebelisoa, ho fokotsa boima ba lihlahisoa, haholo-holo lebaleng la lisebelisoa tsa likoloi.

Lilemong tsa morao tjena, tšebeliso ea "nucleating agent" polypropylene e eketsehile butle-butle.Limela tse ngata tsa petrochemical li eketsa "nucleating agent" ts'ebetsong ea granulation ea ho hlahisa resin ea polypropylene.Ho eketsoa ha moemeli oa nucleating ha ho na phello e mpe feela 'mala oa polypropylene, empa hape ho ka ntlafatsa ho hanyetsa mocheso le ho benya ha resin ea polypropylene.5%, le hoja palo ea tlatsetso e nyenyane, empa ka lebaka la theko ea moemeli oa nucleating e theko e boima (ho ea ka boleng ba sehlahisoa le boemo ba tekheniki, theko e atisa ho ba likete tse mashome ho isa ho tse makholo a mahlano), e tla eketsa litšenyehelo tsa polypropylene resin lithane tse makholo a 'maloa li-yuan.

Sebopeho sa polypropylene se entsoe ka lisebelisoa tse latelang tse tala ka boima ba 'mele:

resin ea polypropylene100;

Mocheso o tsitsitseng 0,05 ~ 2;

Stearate tšepe letsoai 0.02 ~ 0.5;

Inorganic filler 0,05 ~ 3;

Moemeli oa "nucleating agent" 0.01 ~ 0.2.

Polypropylene resin composite ka ho sebelisa polypropylene resin, thermal stabilizer, stearic acid, letsoai la tšepe, inorganic filler le palo e nyane ea "nucleating agent" e ne e kopantsoe ho lokisoa ha granulation, ho tiea ho hoholo, ho hanyetsa mocheso o phahameng le molemo o theko e tlase, theknoloji ea ho itokisa e bonolo, resin ea polypropylene. composite e ka sebelisoa likoloing, lisebelisoa tsa ntlo le ntlo le masimo a mang.
