Application
Iyo PP (polypropylene) tsvimbo ndeye semi-crystalline zvinhu iyo inomira kunze nekuda kwekusiyana kwayo kusanganisa kwemuviri uye mechaniki zvinhu. Chimwe chezvinhu zvinonyanya kukosha kuoma kwayo uye nzvimbo yakakwirira yekunyungudika, iyo inoisiyanisa kubva kune zvimwe zvinhu zvakadai sePE (polyethylene). Nepo iyo homopolymer mhando yePP inogona kuita brittle kana yakafumurwa kune tembiricha yakakwira kupfuura 0 ° C, zvinhu zvakawanda zvekutengesa zvePP zvinogadzirwa sezvisina kurongeka copolymers kana clamp copolymers ane akasiyana muzana ethylene.
Random copolymers anowanzo aine 1 kusvika 4% ethylene, nepo clamp copolymers ane reshiyo yepamusoro ye ethylene. Iyi copolymerization maitiro inoguma mune PP zvinhu zvine yakaderera kupisa kupisa tembiricha (100 ° C) zvichienzaniswa nehomopolymer PP. Kunyangwe iyo copolymer mhando PP zvinhu zvingave zvakaderera kujeka, kupenya, uye kuoma, inoratidza simba rakasimba rekuita. Sezvo iyo ethylene yemukati mucopolymer inowedzera, iyo yakazara simba rePP zvinhu zvinowedzerawo, zvichiita kuti ive sarudzo inogoneka kune akasiyana maapplication.
Humwe hunhu hwakakosha hwePP ndeyekunyorovesa kwayo Vicat tembiricha, iri 150 ° C. Uku kupikisa tembiricha yakakwira, yakasanganiswa neyemhando yepamusoro yecrystallinity, inokonzeresa kuoma kwepamusoro uye kuramba kwekukwenya. Izvi zvinhu zvinoita kuti PP ive sarudzo yakanakira maapplication uko kusimba uye kuramba kupfeka uye kubvarura kwakakosha.
Uyezve, PP inozivikanwa nekupokana kwayo nekupwanya kwekushushikana kwezvakatipoteredza, iri nyaya yakajairika mune zvimwe zvinhu zvakawanda. Izvi zvinoita kuti ive sarudzo yakavimbika yekushandiswa munzvimbo dzinosangana nemakemikari, mwando, kana zvimwe zvinonetsa.
Pamusoro pemakina ezvivakwa, PP inopawo yakanakisa processability. Inogona kuumbwa zviri nyore uye kuumbwa uchishandisa akasiyana ekugadzira maitiro, senge jekiseni molding, extrusion, uye blow molding. Izvi zvakasiyana-siyana, zvakasanganiswa nezvimwe zvivakwa zvaro, zvinoita kuti PP ive sarudzo yakakurumbira kune dzakasiyana siyana dzekushandisa, kusanganisira kurongedza, zvikamu zvemotokari, uye zvigadzirwa zvevatengi.
Pakazere, iyo PP tsvimbo chinhu chinochinja-chinja uye chakasimba chinopa yakasarudzika musanganiswa wemuviri uye wemuchina zvivakwa. Iyo yakakwirira yekunyungudika, yakanakisa kuomarara kwepasi uye kukwenya kuramba, uye kuramba kune kwezvakatipoteredza kusagadzikana kupaza kunoita kuti ive sarudzo yakanakira yemhando dzakasiyana dzekushandisa. Kunyangwe iwe uchitsvaga chinhu chinogona kumira tembiricha yakakwira, kuramba kupfeka uye kubvaruka, kana zvese zviri zviviri, iyo PP tsvimbo isarudzo yakavimbika uye ine hunyanzvi ine chokwadi chekuzadzisa zvaunoda.
