Nucleating tus neeg saib xyuas yog ib hom kev ua haujlwm tshiab ntxiv uas tuaj yeem txhim kho lub cev thiab cov neeg siv hluav taws xob, kub ua rau muaj zog, thiab lwm yam los ntawm kev hloov pauv cov crystallization ntawm cov resins. Nws yog dav siv nyob rau hauv cov txheej txheem ntau lawm, crystalline xws li polyethylene hauv lub tsheb, cov khoom siv hauv tsev, khoom noj khoom haus, thiab kho mob. Piv txwv li, Nucileating tus neeg saib xyuas yog cov khoom tseem ceeb nyob rau hauv kev tsim cov kev ua tau zoo xws li highstallorene, thiab siab polypropylene, thiab cov khoom siv polypropylene, thiab cov khoom siv polypropylenalylene, thiab cov ntawv thov polypropylenally, thiab cov khoom siv polypropylenally, thiab cov khoom siv polypropylene, thiab cov khoom siv polypropylenalylene, thiab cov khoom siv polypropylenally, thiab cov khoom siv polypropylene, thiab cov khoom siv polypropylenalylene, thiab cov ntawv thov polypropylenal rau cov ntaub ntawv nyias nyias-muaj koob. Los ntawm kev ntxiv cov neeg sawv cev tshwj xeeb nucleating, resins nrog kev txhim kho transparency, rigidity, thiab kev nruj yuav ua tau. Nrog rau qhov nce loj hauv kev tsim cov kev ua haujlwm ntawm cov neeg sawv cev ntawm Nucleasting thiab Lithium roj teeb separators, muaj peev xwm txhim kho lub peev xwm rau kev ua lag luam nucileting rau hauv.
Muaj ntau homNucileating tus sawv cev, thiab lawv cov khoom lag luam txuas ntxiv txhim kho. Raws li cov ntaub ntawv sib txawv uas tau tsim los ntawm Nucileating tus sawv cev, lawv tuaj yeem muab faib ua α-crystalline cov neeg sawv cev thiab β-crystalline tus sawv cev. Thiab α-crystalline tus sawv cev tuaj yeem faib rau hauv Inorganic, organic, thiab hom sib txawv raws li lawv cov qauv sib txawv. Inorganic nucileating nuclesating feem ntau suav nrog cov neeg sawv cev ntawm lub siab ntev xws li mica calcium, thiab yooj yim kom tau tab sis muaj kev tsis zoo transparency thiab ci ci. Organic nucileating cov neeg sawv cev tsuas yog suav nrog cov neeg sawv cev roj, thiab cov neeg tsim cov khoom siv tsis zoo, thiab muaj ntau yam zoo tshaj plaws, thiab cov khoom lag luam loj tshaj plaws, thiab cov khoom lag luam loj tshaj plaws ob qho tib si thiab thoob ntiaj teb. Polymer Nucileating tus sawv cev yog tsuas yog siab-yaj-taw tes polymeric nucileating tus sawv cev, xws li polyvinylclohexane thiab polyvinylpentane. β-crystalline nucileating cov neeg sawv cev feem ntau muaj ob hom: ib tug me me polycyclic qauv, thiab cov muaj cov duab ntawm cov hlau los ntawm pawg Iia ntawm lub rooj ntu. β-crystalline nucileating agent kom cov thermal deformation kub ntawm cov khoom thaum txhim kho lawv kev cuam tshuam tsis kam.
Piv txwv ntawm cov khoom lag luam thiab cov ntawv thov ntawm cov sawv cev nucleting
| Khoom | Hauj loo piav qhia | Cov Ntawv Thov |
| Pob tshab Nucleating Tus Neeg Saib Xyuas | Nws tuaj yeem txhim kho lub pob tshab ntawm lub resin, txo covze los ntawm ntau dua 60%, Thaum nce cov cua sov dedortion kub thiab crystallization kub ntawm lub resin los ntawm 5 ~ 10 ℃, thiab txhim kho cov modulus flexural los ntawm 10% ~ 15%. Nws tseem Luv ntawm lub voj voog moulding, Kev txhim kho ntau lawm, thiab tswj hwm cov khoom seem ruaj khov. | Siab yaj Index Polypropylene (los yog siab mi polypropylene) |
| Rigidifying nucleating tus neeg saib xyuas | Nws tuaj yeem txhim kho cov cuab yeej siv ntawm cov cob, nrog kev nce ntxiv hauv Flexural Modulus thiab khoov tau lub zog ntawm ntau dua 20%, Raws li zoo raws li kev nce hauv tshav kub distortion kub los ntawm 15 ~ 25 ℃. Kuj tseem muaj kev txhim kho thiab kev txhim kho kom zoo rau hauv ntau yam xws li crystallization kub thiab cuam tshuam lub zog, ua rau muaj kev sib tw ua kom muaj zog thiab txo qis warpage deformation ntawm cov khoom. | Siab yaj Index polyPropylene, cov kev loj-muaj zog, thiab cov khoom siv polypropylene, hloov kho cov khoom siv nyias-phab ntsa |
| β-crystalline ua kom tawv nqaij nucileating | Nws tuaj yeem ua tau zoo heev ntawm kev tsim ntawm β-crystalline polypropylene, nrog β-crystalline ntsuas tus nqi ntawm ntau dua 80%, ho txhim kho qhov cuam tshuam lub zog ntawm polypropylene cob, Thiab qhov ua tau zoo dua tuaj yeem ncav ntau dua 3 zaug. | Siab yaj Index polyPropylene, cov kev loj-nrawm, siab-tofness, thiab siab-crystallization polypropylene, β-crystallene |
