Txij li thaum lub invention ntawm plastics los ntawm American Baekeland ib puas xyoo dhau los, plastics tau sai heev thoob plaws lub ntiaj teb no nrog nws cov txiaj ntsig zoo, pab txhawb tib neeg lub neej. Niaj hnub no, cov khoom siv yas tau dhau los ua cov khoom tsim nyog hauv lub neej niaj hnub, thiab kev siv cov khoom siv yas, tshwj xeeb tshaj yog cov khoom yas pob tshab, tau loj hlob sai txhua xyoo.

Pob tshab nucleating tus neeg saib xyuas yog ib pab pawg tshwj xeeb ntawm nucleating tus neeg sawv cev, uas muaj cov khoom sib sau ua ke ntawm tus kheej polymerization ntawm lub cev nws tus kheej, thiab tuaj yeem yaj hauv yaj polypropylene los ua homogeneous tov. Thaum cov polymer txias, tus neeg sawv cev pob tshab crystallizes thiab tsim cov fiber ntau zoo li lub network, uas yog faib sib npaug thiab tsawg dua qhov wavelength ntawm pom lub teeb. Raws li ib tug heterogeneous siv lead ua core, lub nucleation ceev ntawm polypropylene yog nce, thiab cov uniform thiab refined spherulite yog tsim, uas txo cov refraction thiab tawg ntawm lub teeb thiab ua rau kom cov pob tshab.

Uni-NUCA muaj qhov zoo tshaj plaws ntawm kev poob qis. Nyob rau hauv tib qhov kev nyab xeeb qhov tseem ceeb (raws li tus qauv ntawm kev lag luam), tus nqi ntawm Uni-NUCA tsawg dua 20% dua li lwm cov nucleating agents! Anc tsim crystal xiav pom kev zoo siab.

Piv nrog rau lwm cov nucleating cov neeg ua haujlwm, cov khoom siv kho tshuab ntawm PP cov khoom tau txhim kho pom tseeb los ntawm kev ntxiv Uni-NUCA.

Piv nrog rau lwm cov tshuaj, Uni-NUCA muaj txiaj ntsig zoo:

Kev txuag nqi - kev siv Uni-NUCA yuav txuag tau 20% ntawm tus nqi ntawm cov khoom siv ntxiv nrog tib qhov txiaj ntsig ntawm cov nqi hluav taws xob.
Kev ua haujlwm kub qis - lub meltinq point ntawm Uni-NUCA ze rau PP thiab yooj yim yaj blending.
Zog txuag - txuag 20% ​​kev siv hluav taws xob los ntawm kev ntxiv Uni-NUCA hauv cov khoom PP.
Beautiull-Uni-NUCA txhim kho cov tsos ntawm cov khoom siv Polypropylene thiab tsim cov siv lead ua xiav pom kev zoo.
