Taw qhia ntawm Qee Cov Khoom Noj Qib Plastics

Kev Tshawb Fawb Txog Kev Paub Txog Kev Noj Qab Haus Huv ntawm PP, PC, PS, Tritan Yas Dej Haus Dej

Cov taub dej yas hauv dej tuaj yeem pom nyob txhua qhov chaw hauv lub neej. Lub taub dej yas ntim tiv taus kom ntog, nqa tau yooj yim, thiab cov qauv zoo nkauj hauv lub ntsej muag, yog li ntau tus neeg nyiam xaiv lub hnab yas dej thaum yuav cov fwj dej. Qhov tseeb, feem ntau cov neeg tsis paub txog cov khoom siv ntawm cov taub dej yas, thiab feem ntau tsis quav ntsej txog kev faib tawm thiab kev nyab xeeb ntawm cov taub dej cov ntaub ntawv, thiab feem ntau tsis quav ntsej cov khoom kev nyab xeeb ntawm cov taub dej.

Cov khoom siv rau cov yas hwj yas yog Tritan, PP yas, PC yas, PS yas. PC yog polycarbonate, PP yog polypropylene, PS yog polystyrene, thiab Tritan yog lub cim tshiab ntawm cov khoom siv copolyester.

PP yog ib qho ntawm cov ntaub ntawv yas uas muaj kev nyab xeeb tshaj plaws tam sim no. Nws tuaj yeem tiv taus kev kub nyhiab thiab tuaj yeem tso rau hauv lub qhov cub microwave. Nws muaj cov cua kub zoo tiv thaiv, tab sis nws tsis muaj zog, yooj yim tawg, thiab muaj pob tshab.

Cov khoom siv hauv PC muaj bisphenol A, uas yuav tso tawm thaum raug tshav kub. Lub sijhawm ntev uas tau txais cov nyiaj ntawm bisphenol A yuav tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. Qee lub tebchaws thiab cov cheeb tsam tau txwv lossis txwv tsis pub PC.

PS cov khoom yog ib cov khoom siv uas tsis tshua muaj neeg siab thiab lub ntsej muag siab. Nws yog qhov yooj yim luam tawm, thiab tuaj yeem ua xim dawb, tsis muaj ntxhiab, tsis qab, tsis muaj mob, thiab tsis ua rau fungus kev loj hlob. Yog li ntawd, nws tau dhau los ua cov ntaub ntawv 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 rau cov ntaub ntawv uas tuaj yeem hloov PC.

Hauv cov keeb kwm kev ua lag luam no, Eastman ntawm Tebchaws Meskas tau txhim kho ib tiam tshiab ntawm tshuab luam ntawv Tritan. Nws qhov zoo yog dab tsi?

1. Cov permeability zoo, lub teeb xa mus> 90%, taws kub nnyiab <1%, nrog cov lus zoo li crystal, yog li Tritan fwj muaj pob tshab heev thiab meej zoo li iav.

2. Hais txog kev siv tshuaj lom neeg, cov khoom siv Tritan nyob rau qhov kom zoo dua qub, yog li Tritan fwj tuaj yeem ntxuav thiab tua kab mob nrog ntau yam tshuaj ntxuav, thiab lawv tsis ntshai xeb.

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