I-Polypropylene luhlobo lweplastiki esetyenziswa rhoqo kuyo yonke into ukusuka kwiibhotile kunye nezikhongozeli ukuya kwizinto zokupakisha. Ukungafihli kwi-polypropylene kunokwandiswa ngokongeza imathiriyeli ethile ebizwa ngokuba yi-clarifying agent. Ezi zinokuthi zibe zii-agent ezicacileyo ezisetyenziselwa ukucacisa ukucaca (okanye ukubona ngenzuzo) njengoko kufunyenwe kwiinkqubo kunye neziphumo zezibonelelo zezinto ezikhoyo kwaye siya kujonga ngakumbi kwinxalenye yokucacisa i-agent edlala kwiipropati ezibonakalayo ze-Top Choosing Chemical polypropylene kunye nokucaca kwemveliso kunye nomgangatho ophunyeziweyo.
Transparanizing agents izongezo i-arhente yokucacisa i-polypropylene elubala ngakumbi. Kukholelwa ukuba oku bakufeza ngokunciphisa ukukhanya okusasazeka njengoko ukukhanya kungena kwimathiriyeli kwaye yongeza ukucaca okuphuculweyo kwemathiriyeli. Kwakhona, xa befaka i-agent ecacileyo kwi-polypropylene, inceda abenzi bavelise imbonakalo ecacileyo, imveliso ekhangeleka kakuhle.
Ke isizathu sokuba i-ejenti zokucacisa zisebenze kungenxa yokuba zenza i-polypropylene ibe yikristale ngakumbi. Iziganeko zokusondela kweeamolekyu, ngoko ke zibe yipateni eqhelekileyo, zibizwa rhoqo njenge-crystallinity, iphezulu ngakumbi i-crystallinity exeliweyo, ngakumbi iimpawu ezibonakalayo ze-polypropylene ziya kuba ngcono (ukungafihli, ukukhanya.) Ii-arhente zokucacisa nazo zinegalelo ekunyukeni kweekristale kwizinto ezicacileyo ze-polypropylene kunye nokuphucula ukucaca.
Kukho inani lezinye ii-arhente zokucacisa ezinokuthi zisetyenziswe kwiKhemikhali yokuKhetha okuphezulu polypropylene nucleated ukuqhubekeka. Imizekelo ethile yezi zinto ibandakanya i-nucleating agents, i-sorbitol derivates kunye nezinto ezithile eziphilayo. Ngalunye lwezo ntlobo ze-ejenti yokucacisa isebenza ngendlela eyahlukileyo kancinane ukomeleza ukucaca kwepolypropylene, kwaye abavelisi beresin banokukhetha iiarhente ezahlukeneyo ngokuxhomekeke kwiimpawu ezichanekileyo abazifunayo kwiimveliso zabo.
Kuye kwafunyaniswa ukuba iintlobo ezahlukeneyo zeenzuzo ziphuma ekusebenziseni i-agent ecacileyo ekulungiseleleni i-agent ye-nucleating ye-polypropylene. Enye yeenzuzo eziphambili ze-agent ezinjalo kukuba ziyakwazi ukuphucula umgangatho wezinto eziphathekayo, okwenza kube nomtsalane ngakumbi njengemveliso yorhwebo. Ukongeza, ukuchasana kunye namandla epolypropylene kunokwandiswa ngabacacisi, kwaye iimveliso eziphuma kule resin zinokuthembeka okungcono kunye nobomi obude.
Ukuba kubanda ukhetha i-arhente yokucacisa kuqulunqo lwakho lwePP ngoko kuqala kufuneka uchonge ukuba zeziphi iimpawu ozilindeleyo kwiimveliso zakho. Kolunye usetyenziso, izicacisi ezahlukeneyo ziya kusebenza ngcono, kwaye kubalulekile ukujonga iinketho zakho ngokufutshane ngaphambi kokuba wenze isigqibo. Unokukhetha ukwenza ishishini kunye nomboneleli othembekileyo onje ngeTop Choosing Chemical kunye nokusebenzisa kuphela iiarhente zokucacisa ezikwinqanaba eliphezulu polypropylene arhente nucleating izinto.
