I-ejenti ye-nucleatingilungele amapulasitiki ekristalu angaphelele njenge-polyethylene ne-polypropylene.Ngokushintsha ukuziphatha kwe-crystallization ye-resin, ingasheshisa izinga le-crystallization, ikhulise ukuminyana kwe-crystallization futhi ikhuthaze ukulinganisa okuncane kosayizi wokusanhlamvu, ukuze kufinyezwe umjikelezo wokubumba, kuthuthukise ukucaca kanye nobuso bomkhiqizo.Isengezo esisha esisebenzayo sezakhiwo zomzimba nezomshini ezifana nokucwebezela, amandla aqinile, ukuqina, izinga lokushisa lokuhlanekezelwa kokushisa, ukumelana nomthelela, nokumelana nokukhuphuka.

I-ejenti ye-nucleatingisho isengezo samakhemikhali esisebenzayo esingashintsha ingxenye yokuziphatha kwekristalu, sithuthukise ukucaca, ukuqina, isicwebezelisi esingaphezulu, ukuqina komthelela kanye nezinga lokushisa lokushintsha okushisayo komkhiqizo, sifinyeze umjikelezo wokubumba umkhiqizo, futhi sithuthukise ukucutshungulwa nokusebenza kokusetshenziswa komkhiqizo. umkhiqizo.

Ii-nucleating agentisetshenziswa njengomsizi wokuguqula we-polymer, futhi indlela yayo yokusebenza ikakhulukazi: esimweni esincibilikisiwe, njengoba i-nucleating agent inikeza i-crystal nucleus edingekayo, i-polymer iyashintsha isuka ku-nucleation yasekuqaleni ye-homogeneous kuya ku-nucleation ehlukahlukene, ngaleyo ndlela, i-crystallization. isivinini siyashesha, ukwakheka okusanhlamvu kuyacwengisiswa, futhi kunenzuzo ukuthuthukisa ukuqina komkhiqizo, ukunciphisa umjikelezo wokubumba, ukugcina ukuqina komkhiqizo wokugcina, ukuvimbela ukuhlakazeka kokukhanya, ukuthuthukisa ukucaca kanye nesicwebezelisi sendawo kanye nomzimba kanye izakhiwo zemishini ye-polymer.(njengokuqina, i-modulus), finyeza umjikelezo wokucubungula, njll. Njengesigaba esibalulekile sama-nucleating agents, umsebenzi oyinhloko we-ejenti ebonakalayo ukuthuthukisa umphumela we-optical we-polymer.Ucwaningo nokuthuthukiswa kwama-nucleating agents ezweni lami kwaqala ngeminyaka yawo-1980, futhi kunezinhlobo eziningi.Manje ama-nucleating agents asebenzayo, ashibhile futhi athengiswayo angahlukaniswa ikakhulukazi ama-inorganic nucleating agents, ama-organic nucleating agents kanye nama-polymer nucleating agents..Ukwengeza, i-ejenti yokuguqula eguqula ifomu le-α-crystal ku-PP ibe ifomu le-β-crystal ngokuvamile liphinde lihlukaniswe njenge-nucleating agent.
