A na-ejikarị ihe mkpuchi nke polypropylene eme ihe maka mkpuchi nke akpa akpa akwa na akwa akwa. Mgbe mkpuchi gasịrị, enwere ike iji akpa kpara akpa na-enweghị mkpuchi akpa polyene. A na-emeziwanye ike na arụmọrụ zuru oke nke akpa a kpara akpa n'ihi na a na-ekpuchi ihe nkiri mgbasa ozi polypropylene ozugbo na akpa a kpara akpa, na ojiji dị mma, a na-ebelatakwa ọnụ ahịa mmepụta ihe.

State Building Materials Agency (National Building Materials Bureau) guzobere okwu & lt; 1997> No.079 na November 1997, na-akọwa na a ga-eji laminated akpa akpa maka nkwakọ nke ciment na ndị ọzọ ngwaahịa. N'otu oge ahụ, site na mmepe nke ụlọ ọrụ nkwakọ ngwaahịa ụlọ, ọnụ ọgụgụ ojiji na usoro nke agba agba PP ji nwayọọ nwayọọ gbasaa. Onye nrụpụta rọba mbụ zụtara ahịrị mmepụta nke rọba na akpa mejupụtara akpa, gbanwere site na akpa akpa PE nke ime ime PP nke mbụ wee bụrụ akpa mkpuchi abụọ na otu akwụkwọ plastik mejupụtara akpa atọ na otu, yana ahịa ahịa nke ọkwa ọkwa. PP na-abawanye kwa ụbọchị. Ọkwa PP agba agba dị n'ime ụlọ siri ike.
nyere n'elu, anyị dabeere na izugbe T30S na 2401 (MFR = 2 ~ 4 g / 10min) na ọma mepụtara pụrụ iche ihe nke mkpuchi ọkwa (MFR = 20 ~ 32 min, tensile ike 24.0 MPa) site na-achịkwa mmebi mgbe agwakọta.

N'oge usoro mmepe ahụ, a na-eme ọtụtụ nyocha na nhọrọ nke ndị na-ahụ maka ịdị arọ molecular na ihe ndị ọzọ na-emepụta ihe, ngwakọta na plasticizing nke akụrụngwa na usoro ndị metụtara ya. Mgbe nyochachara nke ọma, a na-ekpebi usoro nhazi na mmepụta nke mkpuchi PP. na-etolite ahịrị mmepụta uka. enwetara nsonaazụ na-eju afọ site na ọtụtụ ngwa, nke na-egosipụta mgbe niile ịdị mma nke ngwaahịa ahụ, mmiri na-agbaze dị mma, imepụta ihe nkiri edo edo, obere shrinkage, ike peel dị elu na nrapado dị elu. 2. uru akụ na ụba atumatu:

Ọnụahịa nke ihe pụrụ iche kwa ton nke mkpuchi bụ ihe dị ka yuan 2,000 dị elu karịa ọnụahịa nke akụrụngwa. Mgbe i wepụrụ ngwa, ọrụ, akụrụngwa, mbelata ụgwọ ọrụ na mmefu ndị ọzọ nke yuan 150, uru net kwa ton nke ihe pụrụ iche bụ yuan 1500. The kwa afọ mmepụta nke mmepụta akara (gbakọọ extruder na ịghasa dayameta nke 65) bụ 350-450 tọn, na kwa afọ net tax nwere ike iru karịa 500000 yuan. ọ bụrụ na ị na-eji nnukwu ịghasa extruder, arụpụtaghị ihe dị elu. Ka ọ dị ugbu a, China nwere ihe karịrị 1000 nnukwu ụlọ ọrụ akpa akpa, obodo nta na obodo na ụlọ ọrụ nkeonwe enweghị ọtụtụ. Ọrụ a nwere atụmanya sara mbara.
Nke abụọ, teknụzụ nkwadebe nke polypropylene jụrụ masterbatch polypropylene jụrụ masterbatch bụ polypropylene dabeere masterbatch, tumadi na-eji belata okpomọkụ nke polypropylene spinning na plastic ngwaahịa na nhazi, karịsịa na polypropylene spinning magburu onwe mmetụta, ma na-eji na mmepụta nke polypropylene ịfụ. ihe nkiri, akpa textile, monofilament, ngwaahịa ịkpụzi injection enwetawokwa nsonaazụ dị mma.
