Daim Ntawv Thov

Txij li thaum Asmeskas Baekeland tau tsim cov yas ib puas xyoo dhau los, cov yas tau nthuav dav sai sai thoob plaws ntiaj teb nrog nws cov txiaj ntsig loj heev, ua rau tib neeg lub neej yooj yim heev. Niaj hnub no, cov khoom yas tau dhau los ua qhov tseem ceeb ntawm lub neej txhua hnub, thiab kev siv cov khoom yas, tshwj xeeb tshaj yog cov khoom yas pob tshab, tab tom loj hlob sai txhua xyoo.

Tus neeg sawv cev nucleating pob tshab yog ib pawg tshwj xeeb ntawm tus neeg sawv cev nucleating, uas muaj cov khoom sib sau ua ke ntawm tus kheej polymerization ntawm lub cev nws tus kheej, thiab tuaj yeem yaj rau hauv polypropylene yaj los ua cov tshuaj homogeneous. Thaum lub polymer txias, tus neeg sawv cev pob tshab crystallizes thiab tsim cov fiber-zoo li network, uas tau faib sib npaug thiab tsawg dua qhov wavelength ntawm lub teeb pom kev zoo. Raws li lub hauv paus siv lead ua heterogeneous, qhov ceev ntawm nucleation ntawm polypropylene nce ntxiv, thiab cov spherulite sib xws thiab refined tau tsim, uas txo qhov refraction thiab scattering ntawm lub teeb thiab ua rau kom pom tseeb.

Uni-NUCA muaj qhov zoo dua ntawm kev txo cov pa phem. Hauv tib qho nqi pa phem (raws li tus qauv ntawm kev lag luam), qhov ntau ntawm Uni-NUCA tsawg dua 20% piv rau lwm cov neeg sawv cev nucleating! Thiab tsim kom muaj kev xav xiav crystal.

Piv nrog rau lwm cov neeg sawv cev nucleating, cov khoom siv kho tshuab ntawm cov khoom PP tau zoo dua los ntawm kev ntxiv Uni-NUCA.

Piv nrog lwm cov neeg sawv cev, Uni-NUCA muaj cov txiaj ntsig zoo:

Kev txuag nqi - kev siv Uni-NUCA yuav txuag tau 20% ntawm tus nqi ntawm cov khoom ntxiv nrog tib qho txiaj ntsig ntawm cov pa taws.
Kev ua haujlwm kub qis dua - qhov taw tes yaj ntawm Uni-NUCA ze rau PP thiab yooj yim yaj sib xyaw.
Siv zog tsawg - txuag tau 20% kev siv zog los ntawm kev ntxiv Uni-NUCA hauv cov khoom PP.
Beautiull – Uni-NUCA ua kom cov khoom Polypropylene zoo nkauj dua thiab tsim cov khoom siv xiav uas pom tseeb.
