Uyini umehluko phakathi kwenkomishi yepulasitiki ye-pc nenkomishi yepulasitiki ye-pp

inkomishi yepulasitiki ye-pc ibhekisela enkomishini yepulasitiki eyenziwe ngezinto ze-polycarbonate, inombolo engezansi ingu-7;pp inkomishi yepulasitiki ibhekisela enkomishini yepulasitiki eyenziwe nge-polypropylene, inombolo engezansi ngu-5. inkomishi yepulasitiki ye-pc kanye nomehluko wenkomishi yepulasitiki ye-pp ikakhulukazi inamaphuzu alandelayo:

I-1, i-PC impahla yokudlulisa inkomishi yepulasitiki yinhle, futhi ilula kunengilazi, intengo ephansi, inkomishi yepulasitiki yezinto ezibonakalayo ye-PC ingamelana nezinga lokushisa -30 ℃ ~ 140 ℃, vele uthi lokhu okuqukethwe kulokhu kushisa akuqhekeki, kuyancibilika.

2, inkomishi yepulasitiki ye-PP ilula impela, akulula ukuyiphula;Ukumelana nokushisa okuhle, ngokungangabazeki kwezinto ezinobuthi, ezinzile futhi eziphephile;Ububi bokudlulisa ukukhanya bumpofu kancane.

I-3, ubulukhuni be-PC yepulasitiki buphakeme kunobulukhuni be-plastic PP yendawo yonke, i-PP impahla eluhlaza i-translucent Milky emhlophe, i-PC eluhlaza okokusebenza isobala.I-PP yaziwa nangokuthi ukuqina kwerabha okuphindwe kayikhulu kungcono, i-PC yaziwa nangokuthi ubulukhuni berabha obungangenwa izinhlamvu kanye namandla omthelela aphezulu kakhulu.

I-4, i-PP iyipulasitiki evamile, ukuminyana kwe-PP kungaphansi kuka-1.0cm/g, i-PP intanta emanzini;I-PC iyipulasitiki yobunjiniyela, ukuminyana kwe-PC kukhulu kuno-1.0cm/g, i-PC icwile emanzini.

I-5, inkomishi yepulasitiki yezinto ezibonakalayo ze-PC ngemuva kokushisa okuphindaphindiwe izokhiqiza i-bisphenol -A nezinye i-carcinogens, indebe yepulasitiki ye-PP ngeke.

inkomishi yepulasitiki ye-pc kanye nenkomishi yepulasitiki ye-pp zivamile izinhlobo ezimbili zenkomishi yamanzi epulasitiki, umehluko omkhulu phakathi kwalokhu kokubili ukuthi inkomishi yepulasitiki ye-pc ayikwazi ukugcwaliswa ngamanzi abilayo kanye nenkomishi yepulasitiki ye-pp ingagcwaliswa ngamanzi abilayo.Ngaphezu kwalokho, okubili ekumelaneni nokushisa, ubulukhuni, ukuminyana nezinye izici kunomehluko othile.pc inkomishi yepulasitiki ngenxa yokumelana nokushisa okuphansi, equkethe amanzi abilayo noma ukukhululwa kwezinto ze-bisphenol, ukulimala empilweni yomuntu, ngakho ayikwazi ukusetshenziselwa ukugcwalisa amanzi abilayo;Inkomishi yepulasitiki ye-pp egcwele amanzi abilayo ayinabo ubuthi, futhi ukumelana nezinga lokushisa eliphezulu kunamandla.
