Kedu ihe dị iche n'etiti PP na MFPP ngwaahịa ngwaahịa?

PP (polypropylene) bụ ihe a na-ahụkarị plastik nke nwere ezigbo nguzogide okpomọkụ, nguzogide kemịkalụ na obere njupụta. MFPP (polypropylene emezigharịrị) bụ ihe polypropylene emegharịrị nwere ike na ike siri ike. Maka ihe abụọ a, edemede a ga-enye mmeghe sayensị na-ewu ewu n'ihe gbasara isi mmalite, usoro nkwadebe, njirimara na mpaghara ngwa.

1. Ihe eji eme ihe nke PP na MFPP A na-akwadebe ihe eji eme ihe nke PP site na polymerizing propylene na mmanụ ala. Propylene bụ ngwaahịa petrochemical nke a na-enweta nke ọma site na usoro mgbawa na ụlọ nrụpụta. MFPP polypropylene emezigharịrị na-eme ka arụmọrụ ya dịkwuo mma site n'ịgbakwunye modifiers na PP nkịtị. Ndị na-eme mgbanwe ndị a nwere ike ịbụ ihe mgbakwunye, ndị na-ejuputa ma ọ bụ ndị ọzọ na-agbanwe agbanwe nke na-agbanwe nhazi na ihe mejupụtara polymer iji nye ya ihe anụ ahụ na kemịkal ka mma.

2. Usoro nkwadebe nke PP na MFPP A na-enweta nkwadebe nke PP karịsịa site na mmeghachi omume polymerization. A na-eme ka propylene monomer ghọọ ụdọ polymer nke nwere ogologo ogologo site n'omume nke onye na-eme ihe. Usoro a nwere ike ime na-aga n'ihu ma ọ bụ na-adịte aka, na oke okpomọkụ na nrụgide. Nkwadebe nke MFPP chọrọ ịgwakọta modifier na PP. Site na ngwakọta agbaze ma ọ bụ ngwakọta ngwọta, a na-agbasasịkwa onye na-agbanwe agbanwe na matrix PP, si otú ahụ na-emeziwanye njirimara nke PP.

3. Njirimara nke PP na MFPP PP nwere ezigbo nkwụsị ọkụ na nkwụsi ike kemịkal. Ọ bụ plastik transperent nke nwere ụfọdụ isi ike na isi ike. Otú ọ dị, ike na ike nke PP nkịtị dị ntakịrị, nke na-eduga na iwebata ihe ndị gbanwere dị ka MFPP. MFPP na-agbakwụnye ụfọdụ mgbanwe na PP iji mee ka MFPP nwee ike ka mma, ike na mmetụta nkwụsị. Ndị na-agbanwe agbanwe nwekwara ike ịgbanwe ihe nrụpụta ọkụ, ihe ọkụ eletrik na nguzogide ihu igwe nke MFPP.

4. A na-ejikarị mpaghara ngwa nke PP na MFPP PP eme ihe ma na-ejikarị emepụta ihe, ngwá ụlọ, ngwa eletriki na ngwaahịa ndị ọzọ na ndụ kwa ụbọchị. N'ihi nguzogide okpomọkụ ya na nguzogide kemịkalụ, a na-ejikwa PP na ọkpọkọ, arịa, valvụ na akụrụngwa ndị ọzọ na ụlọ ọrụ kemịkalụ. A na-ejikarị MFPP eme ihe na ngwa chọrọ ike dị elu na ike siri ike, dị ka akụkụ ụgbọ ala, mkpuchi ngwaahịa eletrọnịkị, ihe ụlọ, wdg.

N'ikpeazụ, PP na MFPP bụ ihe abụọ eji eme plastik. PP nwere njirimara nke nguzogide okpomọkụ, nguzogide corrosion kemịkalụ na njupụta dị ala, na MFPP agbanweela PP na ndabere a iji nweta ike dị mma, ike na mmetụta nkwụsị. Ihe abụọ a na-arụ ọrụ dị mkpa na mpaghara ngwa dị iche iche, na-eweta ịdị mma na mmepe na ndụ anyị na mpaghara mmepụta ihe dị iche iche.
