Isicelo

Selokhu kwasungulwa amapulasitiki yi-American Baekeland eminyakeni eyikhulu edlule, amapulasitiki asakazeke ngokushesha emhlabeni wonke ngezinzuzo zawo ezinkulu, enza lula kakhulu izimpilo zabantu. Namuhla, imikhiqizo yepulasitiki isiyizidingo zokuphila kwansuku zonke, futhi ukusetshenziswa kwemikhiqizo yepulasitiki, ikakhulukazi imikhiqizo yepulasitiki ebonakalayo, ikhula 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 kobungu. Kumanani afanayo we-haze (ngokwezinga lemboni), inani le-Uni-NUCA lingaphansi kwama-20% kunamanye ama-nucleating agents! I-Anc idala umuzwa obonakalayo oluhlaza okwesibhakabhaka.

Qhathanisa namanye ama-nucleating agents, 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 yenani loskungu.
Ukucutshungulwa kwezinga lokushisa eliphansi - iphoyinti le-meltinq le-Uni-NUCA eliseduze ne-PP kanye nokuxutshwa kokuncibilika okulula.
Ukonga amandla - yonga ukusetshenziswa kwamandla okungu-20% ngokungeza i-Uni-NUCA emikhiqizweni ye-PP.
I-Beautiull–Uni-NUCA ithuthukisa ukubukeka kwemikhiqizo ye-Polypropylene futhi idale ukusebenza okubonakalayo okuluhlaza kwekristalu.
