polypropylene resin vim nws muaj qhov zoo rigidity thiab kub tsis kam, thiab tom qab kev hloov kho txhais tau tias nplua nuj, vim tias qhov no maj mam hloov qee cov yas yas, dav siv hauv tsheb, khoom siv hluav taws xob thiab tsev neeg thiab lwm yam.

Tshwj xeeb tshaj yog nyob rau hauv copolymerization polypropylene resin, los ntawm kev nce qib ntawm cov txheej txheem ntau lawm thiab catalyst technology, muab cov khoom lag luam zoo tshaj plaws kev ua tau zoo Tab sis vim muaj kev cuam tshuam tau ua ke rau propylene ntau lawm muaj teeb meem kev nyuaj, tshwj xeeb tshaj yog nyob rau hauv xws li cov khoom toughness thiab rigidity. liquidity, kuj tsis tau tag nrho txaus nyob rau hauv tej qhov chaw ntawm kev thov, yog li ntawd kuj xav tau nyob rau hauv lub hauv paus ntawm cov khoom uas twb muaj lawm muaj feem xyuam rau copolymer polypropylene tom qab kev hloov kho, xws li los ntawm kev ntxiv nucleating tus neeg saib xyuas elastomer inorganic muab tub lim kom tiav cov khoom xws li siab rigidity.

Lub rigidity ntawm cov ntaub ntawv polypropylene nrog siab toughness thiab siab fluidity feem ntau yog txhim kho los ntawm kev ntxiv nucleating tus neeg saib xyuas los yog inorganic muab tub lim.Nrog rau qhov sib ntxiv ntawm inorganic muab tub lim xws li calcium carbonate, talcum hmoov, mica, diatomite, thiab lwm yam, khoov ntawm polypropylene resin Lub zog flexural thiab flexural elastic modulus nce zuj zus, tab sis tib lub sijhawm, elongation thiab cuam tshuam lub zog ntawm polypropylene yuav raug txo, thiab cov xim thiab shrinkage ntawm polypropylene cov khoom yuav raug cuam tshuam.Tsis tas li ntawd, qhov sib ntxiv ntawm ntau cov inorganic fillers yuav txhim kho qhov ntom ntawm cov ntaub ntawv, txwv tsis pub lub teeb yuag ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov tsheb.

Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm nucleating tus neeg sawv cev hauv polypropylene tau maj mam nce.Ntau cov nroj tsuag petrochemical ntxiv nucleating tus neeg sawv cev hauv cov txheej txheem granulation ntawm kev tsim cov polypropylene resin.Qhov sib ntxiv ntawm nucleating tus neeg saib xyuas tsis tsuas yog tsis muaj kev cuam tshuam rau cov xim ntawm polypropylene, tab sis kuj tuaj yeem txhim kho cov cua sov thiab glossiness ntawm polypropylene resin.5%, txawm hais tias qhov sib ntxiv me me, tab sis vim yog tus nqi ntawm nucleating tus neeg saib xyuas yog kim (raws li cov khoom lag luam zoo thiab qib kev, tus nqi feem ntau yog nyob rau hauv kaum tawm txhiab mus rau tsib puas txhiab), yuav nce tus nqi ntawm polypropylene cob tons ntawm ob peb puas yuan.

Cov txheej txheem polypropylene yog tsim los ntawm cov khoom siv raw hauv qab no los ntawm qhov hnyav:

polypropylene cob100;

Thaum tshav kub kub stabilizer 0.05 ~ 2;

Stearate hlau ntsev 0.02 ~ 0.5;

Inorganic muab tub lim 0.05 ~ 3;

Organic nucleating tus neeg sawv cev 0.01 ~ 0.2.

Polypropylene resin composite los ntawm kev siv polypropylene resin, thermal stabilizer, stearic acid, hlau ntsev, inorganic muab tub lim thiab ib tug me me ntawm nucleating tus neeg saib xyuas yog tov granulation npaj, siab rigidity, siab kub tsis kam thiab tsis tshua muaj nqi kom zoo dua, kev npaj technology yog yooj yim, lub polypropylene resin Composite tuaj yeem siv rau hauv tsheb, khoom siv hauv tsev thiab tsev neeg thiab lwm yam.
