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-Transparent Nucleating agent iyiqembu elincane elikhethekile le-nucleating ejenti, elinempahla yokuhlanganisa ye-self polymerization yomzimba ngokwawo, futhi ingancibilika ku-polypropylene encibilikayo ukuze yakhe isixazululo esilinganayo. Lapho i-polymer ipholile, i-ejenti ebonisa ngale icwebezela futhi yakhe inethiwekhi efana nefayibha, esatshalaliswa ngokulinganayo nangaphansi kobude begagasi bokukhanya okubonakalayo. Njengomgogodla we-crystal ohlukile, ukuminyana kwe-nucleation ye-polypropylene kuyanda, futhi iyunifomu ne-spherulite ecwengiwe iyakhiwa, okunciphisa ukuphikiswa nokuhlakazeka 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.

Qhathanisa 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.
