Kev Ntsuam Xyuas Kev Paub Txog Kev Noj Qab Haus Huv ntawm PP, PC, PS, Tritan Yas Dej Lub raj mis

Cov fwj dej yas tuaj yeem pom txhua qhov chaw hauv lub neej.Lub raj mis dej yas tiv taus lub caij nplooj zeeg, yooj yim nqa, thiab zoo nkauj zoo nkauj, yog li ntau tus neeg nyiam xaiv lub raj mis dej yas thaum yuav lub raj mis dej.Qhov tseeb, cov neeg feem coob tsis paub txog cov khoom siv ntawm lub raj mis dej yas, thiab feem ntau tsis xyuam xim rau kev faib tawm thiab kev nyab xeeb ntawm cov khoom siv hauv lub raj mis, thiab feem ntau tsis quav ntsej cov khoom siv kev nyab xeeb ntawm cov fwj dej.

Cov khoom siv rau lub raj mis yas yog Tritan, PP yas, PC yas, PS yas.PC yog polycarbonate, PP yog polypropylene, PS yog polystyrene, thiab Tritan yog ib tiam tshiab ntawm cov khoom siv copolyester.

PP yog ib qho ntawm cov khoom siv yas zoo tshaj plaws tam sim no.Nws tuaj yeem tiv taus qhov kub thiab txias hauv qhov cub microwave.Nws muaj cov cua kub zoo heev, tab sis nws tsis muaj zog, yooj yim tawg, thiab tsis tshua muaj pob tshab.

PC cov khoom muaj bisphenol A, uas yuav raug tso tawm thaum raug tshav kub.Kev noj tshuaj ntev ntev ntawm cov tshuaj bisphenol A yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.Qee lub tebchaws thiab cheeb tsam tau txwv lossis txwv PC.

Cov khoom siv PS yog cov khoom siv nrog cov pob tshab siab heev thiab siab gloss.Nws yog ib qho yooj yim los luam, thiab tuaj yeem ua xim dawb, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, thiab tsis ua rau cov kab mob fungal.Yog li ntawd, nws tau dhau los ua ib qho ntawm cov khoom siv yas nrov dua.

Cov neeg tsim khoom tau ntsib lub siab ntawm kev noj qab haus huv thiab kev tiv thaiv ib puag ncig thiab tab tom nrhiav cov ntaub ntawv uas tuaj yeem hloov PC.

Hauv keeb kwm kev lag luam no, Eastman ntawm Tebchaws Meskas tau tsim ib tiam tshiab ntawm copolyester Tritan.Nws qhov zoo yog dab tsi?

1. Zoo permeability, lub teeb transmittance> 90%, haze <1%, nrog crystal-zoo li luster, yog li lub Tritan lub raj mis yog pob tshab thiab meej zoo li iav.

2. Nyob rau hauv cov nqe lus ntawm cov tshuaj tiv thaiv, Tritan cov ntaub ntawv nyob rau hauv ib tug kiag li kom zoo dua, yog li Tritan fwj tuaj yeem ntxuav thiab tshuaj tua kab mob nrog ntau yam tshuaj detergents, thiab lawv tsis ntshai ntawm corrosion.

3. Nws tsis muaj cov tshuaj phem thiab ua tau raws li qhov yuav tsum tau muaj ntawm kev tiv thaiv ib puag ncig thiab kev noj qab haus huv;zoo toughness, siab cuam tshuam lub zog;kub kub tsis kam ntawm 94 ℃ -109 ℃.
