NONEifanelekile kwiiplastiki zekristale ezingaphelelanga ezifana ne-polyethylene kunye ne-polypropylene.Ngokutshintsha indlela yokuziphatha ye-crystallization ye-resin, inokukhawulezisa izinga le-crystallization, ikhulise ingxinano ye-crystallization kwaye ikhuthaze i-miniaturization yobungakanani bengqolowa, ukwenzela ukuba unciphise umjikelo wokubumba, uphucule ukucaca kunye nomphezulu wemveliso.Isongezo esitsha esisebenzayo somzimba kunye neempawu zoomatshini ezinje ngeglosi, amandla okuqina, ukuqina, ubushushu bokutshintsha ubushushu, ukuchasana nempembelelo, kunye nokuxhathisa kokuhamba.

NONEibhekisa kwisongezo sekhemikhali esisebenzayo esinokutshintsha inxalenye yendlela yokuziphatha kwekristale, ukuphucula ukungafihli, ukuqina, isicwebezelisi somphezulu, ukuqina kwempembelelo kunye nobushushu be-thermal deformation yemveliso, ukunciphisa umjikelo wokubumba imveliso, kunye nokuphucula ukusetyenzwa kunye nokusebenza kwesicelo imveliso.

Ii-agent yokucocaisetyenziswa njengomncedisi wokuguqulwa kwepolymer, kwaye indlela yokusebenza kwayo ikakhulu: kwindawo etyhidiweyo, kuba i-agent ye-nucleating ibonelela ngekristale nucleus efunekayo, utshintsho lwepolymer ukusuka kwi-nucleation ye-homogeneous yasekuqaleni ukuya kwi-heterogeneous nucleation, Ngaloo ndlela, i-crystallization. isantya sikhawuleza, ukwakheka kweenkozo kusulungekisiwe, kwaye kunenzuzo ekuphuculeni ukuqina kwemveliso, ukunciphisa umjikelo wokubumba, ukugcina ukuzinza komgangatho wemveliso yokugqibela, ukuthintela ukusasazwa kokukhanya, ukuphucula ukungafihli kunye neglosi yomhlaba kunye nomzimba kunye nokukhanya. iimpawu zomatshini wepolymer.(njengokuqina, i-modulus), nciphisa umjikelo wokucubungula, njl. Njengeklasi ebalulekileyo ye-nucleating agents, umsebenzi oyintloko we-agent ecacileyo kukuphucula i-optical effect ye-polymer.Uphando kunye nophuhliso lwee-agent ze-nucleating kwilizwe lam lwaqala ngo-1980, kwaye zininzi iintlobo.Ngoku i-agent esebenzayo, ephantsi kunye neyorhwebo ye-nucleating agents inokwahlulwa ikakhulu kwi-inorganic nucleating agents, i-organic nucleating agents kunye ne-polymer nucleating agents..Ukongezelela, i-agent agent eguqula i-α-crystal form kwi-PP kwi-β-crystal form ngokuqhelekileyo ikwahlelwa njenge-nucleating agent.
