Ua ntej, qhia rau peb paub txog ob yam khoom no:
Cov khoom siv PC yog dab tsi?
Hauv kev lag luam, polycarbonate (Polycarbonate) hu ua PC. Qhov tseeb, cov khoom siv PC yog ib qho ntawm peb cov plastics industrialized. Yog vim li cas vim li cas nws yog dav siv nyob rau hauv ntau lawm yog tag nrho txiav txim los ntawm nws cov yam ntxwv. PC muaj qhov tshwj xeeb zoo ntawm fireproof, non-toxic thiab xim. Qhov tseem ceeb yog tias nws muaj lub zog nthuav dav, qhov kub thiab txias tsis kam, thiab zoo extensibility. Qhov tseem ceeb yog qhov zoo ntawm cov khoom tiav yog qhov zoo. Cov no tau dhau los ua kev xaiv rau ntau lub rooj tog xaiv PC ua cov khoom siv raw. Ib qho laj thawj tseem ceeb.
PP khoom yog dab tsi?
PP yog cov ntawv luv ntawm polypropylene (Polypropylene), thiab nws kuj yog qhov peb feem ntau hu ua Fold-fold yas, uas kuj yog ib hom kev lag luam yas. PP yog cov khoom siv hluavtaws, tab sis nws kuj muaj nws qhov zoo thiab qhov tsis zoo. Ntau lub fwj me me yuav ua los ntawm cov khoom siv PP vim tias nws tiv taus qhov kub thiab txias siab tshaj 100 degrees Celsius, yog li nws tsim nyog rau cov kev xav tau ntawm cov dej kub npau npau ntawm cov me nyuam lub fwj. Kev ruaj ntseg ntawm PP yog qhov zoo.

Yog li vim li cas hauv kev lag luam rooj tog, cov ntaub ntawv PC tau maj mam hloov los ntawm PP cov ntaub ntawv? Cov laj thawj yog raws li nram no:
Tus nqi tsim nyog
Cov khoom siv raw khoom tus nqi ntawm PC resin yog ntau dua li ntawm PP. Cov khoom siv phem tshaj plaws ntawm PC yog ntau tshaj 20,000 ib tuj, thiab cov khoom siv raw ntawm PP yog 10,000. PP kuj yog ib qho ntawm cov kev siv ntau tshaj plaws.
Zam kev xav
Nyob rau hauv cov nqe lus ntawm lub teeb transmittance ntawm plastics, PC resin yeej. PC yog ib qho ntawm peb lub pob tshab yas nrog lub teeb pom kev zoo. Cov rooj tog ua tiav yog pob tshab thiab tsis muaj xim. Qhov permeability ntawm pp yog qhov tsis zoo, thiab ib txwm PP muaj qhov tsis txaus ntseeg ntawm huab cua, uas ua rau cov khoom zoo nkauj thiab ua rau cov xim ntau dua, uas ua rau nws siab dua. Kev xaiv ntau yam xim kuj tau dhau los ua kev nyiam rau nws. Yog vim li cas rau txais tos. Kev xaiv nplua nuj, tsis yog ib yam li cov khoom siv PC.
Cov yam ntxwv ntawm cov khoom
Lub hardness thiab toughness ntawm ob plastics no txawv. PC muaj hardness zoo heev, PP muaj hardness tsawg heev nyob rau hauv chav tsev kub, thiab nws yuav yooj yim deformed thiab khoov los ntawm sab nraud quab yuam. Txawm li cas los xij, PP muaj qhov tawv zoo heev, feem ntau hu ua Baizhe kua nplaum, thiab tau siv dav hauv rooj tog. Nws toughness ua rau nws muaj zog dua thiab muaj peev xwm zoo dua load-bearing.
Manufacturability
Lub fluidity ntawm PP txhaj yog zoo heev thiab nws yog ib qho yooj yim rau tsim, thaum lub fluidity ntawm PC yog heev tsis zoo thiab nws yog ib qho nyuaj rau txav cov kua nplaum. Tsis tas li ntawd, PC yog ib qho yooj yim rau decompose thiab hloov xim ntawm qhov kub thiab txias hauv kev txhaj tshuaj molding, thiab kev txhaj tshuaj molding yuav tsum tau customized PC ntsia hlau. Yog li qhov tseeb, tus nqi ua haujlwm ntawm cov khoom PC yog siab dua. Nyob rau tib lub sijhawm, thaum cov khoom txhaj tshuaj PC tau tsim, vim lawv cov yam ntxwv pob tshab thiab yooj yim pom cov npuas thiab impurities hauv, cov txiaj ntsig tau qis heev. Yog tias nws yog lub lag luam high-end, nws yog qhov nyuaj heev los tswj cov khoom zoo ntawm PC, uas kuj ua rau cov nqi tsim khoom tau zoo heev.
Kev nyab xeeb yam
Cov khoom siv PC tuaj yeem decompose bisphenol A, uas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. PC siab kub tsis tsim bisphenol A, tab sis bisphenol A yog raw khoom rau zus tau tej cov PC yas. Tom qab cov synthesis ntawm bisphenol A, PC yog tsim. Tom qab cov tshuaj synthesis, thawj bisphenol A tsis muaj lawm. Nws tsuas yog hais tias cov txheej txheem synthesis no yog txheej txheem, thiab muaj qhov sib txawv ntawm cov txheej txheem, nws nyuaj rau 100% cov tshuaj tiv thaiv tiav, thiab tej zaum yuav muaj cov seem bisphenol A (tej zaum). Thaum PC ntsib qhov kub siab, nws yuav ua rau bisphenol A los nag los ntawm cov yas. Yog li ntawd, yog tias muaj cov seem bisphenol A nyob rau hauv cov khoom, ob qho tib si nag lossis daus txias yuav tshwm sim, thiab nag lossis daus txias yuav qeeb heev.
?
Txhua yam, kev ua tau zoo ntawm PC thiab PP yog qhov sib txawv, thiab nws tsis tuaj yeem txiav txim siab tsuas yog leej twg yog tus zoo thiab leej twg phem. Nws tseem yog qhov tsim nyog los xaiv cov khoom lag luam zoo tshaj plaws rau kev siv. Thiab PP yog siv dav hauv cov rooj tog zaum, uas yog vim li cas PP rooj tog tau maj mam hloov cov rooj tog hauv PC.
