Isicelo

Kusukela kwasungulwa amapulasitiki yi-American Baekeland eminyakeni eyikhulu edlule, amapulasitiki asakazeke ngokushesha emhlabeni wonke ngezinzuzo zawo ezinkulu, okwenza kube lula kakhulu ukuphila kwabantu. Namuhla, imikhiqizo yepulasitiki isibe yizidingo zokuphila kwansuku zonke, futhi ukusetshenziswa kwemikhiqizo yepulasitiki, ikakhulukazi imikhiqizo yepulasitiki esobala, kukhula ngokushesha unyaka nonyaka.

I-ejenti ye-nucleating ecacile iyiqembu elincane elikhethekile le-ejenti ye-nucleating, enempahla yokuhlanganisa yokuzihlanganisa ngokwayo, futhi ingancibilikiswa ku-polypropylene encibilikisiwe ukuze yakhe isixazululo esifanayo. Lapho i-polymer ipholile, i-ejenti ecacile iyakha ikristalu futhi yakhe inethiwekhi efana ne-fiber, esatshalaliswa ngokulinganayo futhi ingaphansi kobude bokukhanya okubonakalayo. Njengengqikithi yekristalu engafani, ubuningi be-nucleation be-polypropylene buyanda, futhi kwakheka i-spherulite efanayo necwengekile, okunciphisa ukugqashuka nokusabalala kokukhanya futhi kwandise ukucaca.

I-Uni-NUCA inenzuzo ephezulu yokuncipha komswakama. Kumanani afanayo omswakama (ngokwezinga lemboni), inani le-Uni-NUCA lingaphansi kuka-20% kunezinye izinto ezibangela ukwakheka kwe-nucleating! I-Anc idala umuzwa wokubona oluhlaza okwesibhakabhaka.

Uma kuqhathaniswa nezinye izinto ezibangela i-nucleating, izakhiwo zemishini zemikhiqizo ye-PP zathuthukiswa ngokusobala ngokungeza i-Uni-NUCA.

Uma kuqhathaniswa namanye ama-ejenti, i-Uni-NUCA inezinzuzo ezingabizi kakhulu:

Ukonga izindleko — ukusetshenziswa kwe-Uni-NUCA kuzokonga u-20% wezindleko zezithasiselo ngomphumela ofanayo wenani lomswakama.
Ukucubungula izinga lokushisa eliphansi — iphuzu lokuncibilika kwe-Uni-NUCA eliseduze ne-PP kanye nokuxuba okulula kokuncibilika.
Yonga amandla - gcina ukusetshenziswa kwamandla okungu-20% ngokufaka i-Uni-NUCA emikhiqizweni ye-PP.
I-Beautiull–Uni-NUCA ithuthukisa ukubukeka kwemikhiqizo ye-Polypropylene futhi idala ama-visual effectives aluhlaza okwesibhakabhaka.
