Kugwiritsa ntchito

Chiyambireni kupangidwa kwa mapulasitiki ndi American Baekeland zaka zana zapitazo, mapulasitiki afalikira padziko lonse lapansi ndi zabwino zake zazikulu, zomwe zimathandizira kwambiri miyoyo ya anthu. Masiku ano, zinthu zapulasitiki zakhala zofunikira pamoyo watsiku ndi tsiku, ndipo kugwiritsa ntchito zinthu zapulasitiki, makamaka zowoneka bwino zapulasitiki, zikukula mwachangu chaka ndi chaka.

Transparent nucleating wothandizira ndi gulu lapadera la nucleating wothandizila, amene ali ndi aggregation katundu kudzikonda polymerization thupi lokha, ndipo akhoza kusungunuka mu sungunula polypropylene kupanga homogeneous njira. Polimayo akazirala, chinthu chowonekera chimanyezimira ndikupanga maukonde ngati ulusi, omwe amagawidwa mofanana komanso mocheperapo kuposa kutalika kwa kuwala kowoneka. Monga pachimake cha kristalo, kuchuluka kwa nucleation ya polypropylene kumawonjezeka, ndipo yunifolomu ndi spherulite yoyengedwa imapangidwa, yomwe imachepetsa kusinthika ndi kubalalitsa kwa kuwala ndikuwonjezera kuwonekera.

Uni-NUCA ili ndi mwayi wapamwamba wa kuchepa kwa chifunga. M'makhalidwe omwewo a haze (malinga ndi momwe amagwirira ntchito), kuchuluka kwa Uni-NUCA ndi kochepera 20% kuposa ma nucleating agents! Anc kupanga mawonekedwe owoneka bwino abuluu.

Poyerekeza ndi ma nucleating agents, makina azinthu za PP adasinthidwa mwachiwonekere powonjezera Uni-NUCA.

Poyerekeza ndi othandizira ena, Uni-NUCA ili ndi zabwino zambiri:

Kupulumutsa mtengo - kugwiritsa ntchito Uni-NUCA kudzapulumutsa 20% ya mtengo wazowonjezera ndi zotsatira zomwezo za mtengo wa haze.
Kutentha kwapang'onopang'ono - malo osungunuka a Uni-NUCA pafupi ndi PP ndi kusakanikirana kosavuta kusungunuka.
Kugwiritsa ntchito mphamvu - pulumutsani 20% kugwiritsa ntchito mphamvu powonjezera Uni-NUCA muzinthu za PP.
Beautiull-Uni-NUCA imathandizira mawonekedwe a zinthu za Polypropylene ndikupanga zowoneka bwino zabuluu.
