Tus neeg sawv cev nucleating yog ib hom khoom siv tshiab uas tuaj yeem txhim kho cov khoom siv lub cev thiab cov khoom siv kho tshuab ntawm cov khoom xws li pob tshab, qhov ci ntsa iab, lub zog tensile, rigidity, kub distortion, cuam tshuam tsis kam, creep tsis kam, thiab lwm yam los ntawm kev hloov pauv tus cwj pwm crystallization ntawm cov resins. Nws yog dav siv hauv cov txheej txheem tsim cov yas crystalline tsis tiav xws li polyethylene thiab polypropylene hauv tsheb, khoom siv hauv tsev, khoom noj, khoom siv hluav taws xob, thiab kev kho mob. Piv txwv li, tus neeg sawv cev nucleating yog cov khoom siv tseem ceeb hauv kev tsim cov resins ua tau zoo xws li polypropylene yaj index siab, tshiab siab-rigidity, siab-toughness, thiab siab-crystallinity polypropylene, β-crystalline polypropylene, thiab cov ntaub ntawv polypropylene hloov kho rau cov ntawv thov nyias-walled tsheb. Los ntawm kev ntxiv cov neeg sawv cev nucleating tshwj xeeb, cov resins nrog kev txhim kho pob tshab, rigidity, thiab toughness tuaj yeem tsim tau. Nrog rau kev nce ntxiv hauv kev tsim khoom hauv tsev ntawm cov polypropylene ua tau zoo uas xav tau kev ntxiv cov neeg sawv cev nucleating thiab kev loj hlob sai hauv kev thov rau lub tsheb sib dua thiab lithium roj teeb separators, muaj peev xwm loj hlob rau kev lag luam nucleating tus neeg sawv cev hauv.

Muaj ntau homcov neeg sawv cev nucleating, thiab lawv cov khoom ua tau zoo txuas ntxiv mus zoo dua. Raws li cov qauv siv lead ua sib txawv uas cov neeg sawv cev nucleating tsim, lawv tuaj yeem muab faib ua α-crystalline nucleating agents thiab β-crystalline nucleating agents. Thiab α-crystalline nucleating agents tuaj yeem muab faib ua inorganic, organic, thiab polymer hom raws li lawv qhov sib txawv ntawm cov qauv. Cov neeg sawv cev inorganic nucleating feem ntau suav nrog cov neeg sawv cev nucleating thaum ntxov xws li talc, calcium oxide, thiab mica, uas pheej yig thiab yooj yim tau txais tab sis muaj qhov tsis pom tseeb thiab qhov ci ntsa iab. Cov neeg sawv cev nucleating feem ntau suav nrog carboxylic acid hlau ntsev, phosphate hlau ntsev, sorbitol benzaldehyde derivatives, thiab lwm yam. Ntawm lawv, sorbitol benzaldehyde derivatives tam sim no yog cov neeg sawv cev nucleating laus tshaj plaws, nrog kev ua tau zoo heev thiab tus nqi qis, thiab tau dhau los ua cov neeg sawv cev nucleating tsim ntau yam, ntau haiv neeg, thiab loj tshaj plaws hauv tsev thiab thoob ntiaj teb. Cov neeg sawv cev polymer nucleating feem ntau yog cov neeg sawv cev polymeric nucleating siab, xws li polyvinylcyclohexane thiab polyvinylpentane. Cov neeg sawv cev β-crystalline nucleating feem ntau muaj ob hom: ib qho me me ntawm cov tshuaj polycyclic nrog cov qauv quasi-planar, thiab cov uas muaj cov dicarboxylic acids thiab oxides, hydroxides, thiab ntsev ntawm cov hlau los ntawm Pawg IIA ntawm lub rooj teev sijhawm. Cov neeg sawv cev β-crystalline nucleating ua kom ntseeg tau tias qhov kub ntawm cov khoom hloov pauv thermal thaum txhim kho lawv qhov kev tiv thaiv kev cuam tshuam.
