Kwiiplastiki, izongezo zidlala indima ebalulekileyo ekwandiseni nasekulungiseni iipropati zemathiriyeli.Ii-agent ze-Nucleating kunye ne-clarifying agents zimbini ezongezo ezinjalo ezineenjongo ezahlukeneyo ekuphumezeni iziphumo ezithile.Ngelixa bobabini bancedisa ukuphucula ukusebenza kweemveliso zeplastiki, kubalulekile ukuqonda umahluko phakathi kwezi arhente zimbini kunye nendlela abanegalelo ngayo kwimveliso yokugqibela.

Ukuqala ngeii-nucleating agents, ezi zongezo zisetyenziselwa ukukhawulezisa inkqubo yecrystallization yeeplastiki.I-Crystallization yenzeka xa amatyathanga epolymer ecwangciswe ngendlela elungelelanisiweyo, ekhokelela kwisakhiwo esingqongqo.Indima ye-agent ye-nucleating kukubonelela ngomphezulu we-polymer chain chain ukubambelela, ukukhuthaza ukubunjwa kwekristale kunye nokwandisa i-crystallinity yonke yezinto.Ngokukhawulezisa i-crystallization, i-nucleating agents ziphucula i-mechanical and thermal properties zeplastiki, zizenza zibe nzima kwaye zikwazi ukumelana nobushushu.

Enye yee-agent ezisetyenziswa ngokuqhelekileyo ze-nucleating yi-talc, iminerali eyaziwa ngokuba namandla okubangela ukubunjwa kwekristale.I-Talc isebenza njenge-agent ye-nucleating, ibonelela ngeendawo ze-nucleation ze-polymer chain chain ukuze zilungelelanise ngeenxa zonke.Ukongezwa kwayo kukhokelela ekunyuseni kwamazinga e-crystallization kunye nesakhiwo sekristale esicolekileyo, okwenza izinto zomelele kwaye zizinze ngakumbi.Ngokuxhomekeke kwiimfuno ezithile kunye neempawu zemveliso yeplastiki, ezinye ii-nucleating agents ezifana ne-sodium benzoate, i-benzoic acid kunye neetyuwa zetsimbi nazo zingasetyenziswa.

Izicacisi, kwelinye icala, zizongezelelo ezandisa ukucaca okubonakalayo kweeplastiki ngokunciphisa inkungu.I-Haze kukusasazeka kokukhanya ngaphakathi kwemathiriyeli, ekhokelela kwinkangeleko yamafu okanye ekhanyayo.Indima yokucacisa i-agent kukuguqula i-matrix ye-polymer, ukunciphisa iziphene kunye nokunciphisa imiphumo yokusabalalisa ukukhanya.Oku kubangela izinto ezicacileyo, ezicacileyo, ezilungele ngokukodwa izicelo ezifana nokupakishwa, iilensi zamehlo kunye neziboniso.

Enye yezinto eziqhelekileyo ezisetyenziselwa ukucacisa i-sorbitol, utywala obushukela obusebenza njenge-nucleating agent.Njenge-ejenti yokucacisa, i-sorbitol inceda ukwenza iikristale ezincinci, ezichazwe kakuhle ngaphakathi kwe-matrix yeplastiki.Ezi kristale zinciphisa ukusasazeka kokukhanya, okunciphisa kakhulu inkungu.I-Sorbitol idla ngokusetyenziswa ngokudibeneyo kunye nezinye ii-agent zokucacisa ezifana ne-benzoin kunye ne-triazine derivatives ukufezekisa ukucaca okufunwayo kunye nokucaca kwemveliso yokugqibela.

Nangona zombini i-nucleating kunye ne-clarifying agents zinenjongo efanayo yokuphucula iimpawu zeplastiki, kufuneka kuqatshelwe ukuba iindlela zabo zokwenza izinto ziyahluka.Iiarhente zeNyukliyaukukhawuleza inkqubo ye-crystallization, ngaloo ndlela iphucula izixhobo zomatshini kunye ne-thermal, ngelixa i-agent ecacisayo iguqula i-matrix ye-polymer ukunciphisa ukukhanya kokukhanya kunye nokwandisa ukucaca kwe-optical.

Ekugqibeleni, i-nucleating agents kunye ne-clarifying agents ziyizongezo ezibalulekileyo kwintsimi yeeplastiki, kwaye i-additive nganye inenjongo ethile.Ii-agent ze-Nucleating ziphucula inkqubo ye-crystallization, ngaloo ndlela iphucula iimpawu zomatshini kunye ne-thermal, ngelixa i-agent ecacisayo inciphisa inkungu kwaye ikhulise ukucaca kwe-optical.Ngokuqonda umahluko phakathi kwezi arhente zimbini, abavelisi banokukhetha isongezelelo esifanelekileyo ukuze bafezekise umphumo oyifunayo kwimveliso yabo yeplastiki, nokuba kukunyuka kwamandla, ukumelana nobushushu okanye ukucaca okubonakalayo.
