I-Polypropylene nucleating agents zezo zixhobo ezikhethekileyo ezincedisa ekuphuculeni iimpawu zezinto eziphathekayo. Ezi zongezo zezinye zezinto eziphambili eziphucula iimveliso zeplastiki. Sigrumba nzulu kubuchwephesha bezi arhente kwaye banokukunceda ukuba ufezekise ntoni.
Ii-agent ze-polypropylene nucleating zi-compounds ezongezwa kwiiplastiki ngexesha lenkqubo yokuvelisa. Le misebenzi yokuKhetha imichiza ePhezulu yenza ii-arhente ziphucule iimpawu zemathiriyeli, ngaloo ndlela zizenza zomelele, zihlale ixesha elide, kwaye zikwazi ukumelana neekhemikhali kunye nobushushu. Apho ukuya polypropylene arhente nucleating ngoncedo lwee-synergists banokuphucula ukusebenza kwemveliso abavelisi abasetyenziselwa ukuhlangabezana ngokupheleleyo neemfuno zabathengi.
Xa i-polypropylene inyibilika kwaye ipholile, igcina enye yeso sakhiwo se-crystalline, esibangela amandla kunye nokuqina kwayo. Polypropylene polypropylene nucleated zisebenza ukulawula ubungakanani kunye nokuqhelaniswa kwezi kristale, kwaye oku kwandisa iimpawu zokusebenza zemathiriyeli. Ukuziphatha ngokubanzi kwecrystallization ye-polypropylene kuphuculwe njengoko i-nucleating agents zikhuthaza ukuba iikristale ezincinci kunye nezifanayo zikhule.
Iimveliso zePlastiki ziqhele ukwenziwa ngesitofu sokubumba. Ngokomzekelo, xa i-polypropylene nucleating agents zongezwa kwi-mold, amaxesha okupholisa ayancipha, imveliso iyanda, kwaye ukuzinza kwemilinganiselo kuphuculwe. Iiarhente zeNyukliya ngokuKhetha iKhemikhali ePhakamileyo ikwathanda ukwehlisa inqanaba lokucutheka okufunyanwa yipolymer ngexesha lokubumba, okukhokelela ekuveliseni ngakumbi, kwiimveliso ezichanekileyo.
Zininzi iintlobo ezahlukeneyo ze i-arhente yokucacisa i-polypropylene, kwaye uhlobo ngalunye luneempawu zalo ezithile kunye neenzuzo. Ezinye ii-nucleating agents zikhuthaza ukwenziwa kweekristale ze-alpha, kanti ezinye zikhuthaza ezo ze-beta. Ukukhethwa kwe-agent ye-nucleating kunokuchaphazela iimpawu zemveliso eyenziwe njengamandla, ukungafihli kunye neempawu ze-thermal.
Ngokusetyenziswa kweMichiza yokuKhetha okuphezulu i-agent ye-nucleating ye-polypropylene ngexesha lenkqubo yokuvelisa, iinkampani zinokuqonda ukonga iindleko kunye nokusebenza kakuhle okwandisiweyo. Ukusetyenziswa kwee-nucleating agents kuya kuvumela ukunciphisa ixesha lomjikelo, ukusetyenziswa kwamandla aphantsi, kwaye kuya kuphucula umgangatho wenxalenye egqityiweyo. Izinto eziluncedo kuzo zonke ezi zikhokelela ekunciphiseni iindleko zokwenziwa kwemveliso kunye nokwanda kweengeniso kubavelisi.
