TereCThalic Acid Cas 100-21-0 / PTA
TerephThalic acid yog feem ntau los tsim polyethylene terephthalate (tsiaj), ib qho hluav taws xob polymer siv los ua cov hwj yas, thiab cov hluavtaws. Tsiaj paub txog nws lub zog, thermal stability, thiab noo noo tsis kam. Tsis tas li ntawd, TereCthalic acid yog siv los ua ntau yam khoom siv, suav nrog:
1. Textiles: Nws yog cov khoom tseem ceeb hauv kev tsim cov polyester fiber, uas siv hauv cov khaub ncaws thiab khoom hauv tsev.
2. Resin: TereFhtalic acid yog siv los npaj ntau yam teeb meem thiab txheej.
3. Yas: Yuav koom nrog kev tsim cov tshuab uas yuav tsum muaj cov tshuaj tiv thaiv kev ua haujlwm.
4. Ntxiv: TereChalic acid tuaj yeem siv los ua cov tshuaj laus hauv cov hluavtaws ntawm lwm cov tebchaw.
Ntim hauv 25 kg ib lub nruas lossis raws cov neeg yuav tsum tau ua.
Txhawm rau kom nyab xeeb khaws cov khoom siv roj ntsha qhia, ua raws cov lus qhia no:
1. Thawv: Khw tshaj tawm cov ntaub qhwv hauv cov ntaub ntawv tsim nyog, xws li iav tsim nyog (HDPE) los tiv thaiv kom tsis txhob muaj paug thiab noo noo).
2. Qhov chaw nyob: khaws cov thawv ntim rau hauv qhov chaw txias, qhuav thiab muaj cua sov kom deb ntawm kev tshav ntuj kom sov thiab cov khoom kub. Tsis txhob cia rau hauv cov chaw nrog cov av noo siab.
3. Qhov kub thiab txias: khaws cia kub nyob hauv cov kev pom zoo, feem ntau qis dua 25 ° F), kom tiv thaiv kev ua kom muaj kev cuam tshuam lossis hloov pauv hauv cov khoom.
4. Daim ntawv lo: daim ntawv lo qhia kom meej rau cov npe tshuaj, cov ntaub ntawv muaj kev phom sij, thiab tau txais hnub kom paub meej tias paub tseeb thiab tuav.
5. Cais: Thov khaws cia ntawm cov khoom siv tsis sib xws, xws li cov oxidants muaj zog, los tiv thaiv qee cov txiaj ntsig.
6. Kev ceev faj kev nyab xeeb: Nco ntsoov kev ceev faj kev nyab xeeb yog nyob rau hauv qhov chaw, nrog rau cov khoom tiv thaiv tus kheej (PPE) rau lwm tus neeg tuav cov khoom siv.
Terephthalic acid yog feem ntau suav hais tias muaj tsawg toxicity, tab sis nws tseem poses muaj qee qhov kev pheej hmoo noj qab haus huv hauv qee kis kev muaj mob. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov peev xwm ua phem rau tib neeg:
1. Inhalation thiab kev sib cuag tawv nqaij: Ntev mus ntev ua rau lub ntsej muag tawv me me los yog vapor yuav ua pa rau cov pa, tawv nqaij thiab qhov muag. Nws raug nquahu kom siv cov khoom tiv thaiv tsim nyog thaum tuav cov khoom no.
2. Kev siv: Txawm hais tias lub acidthalic acid feem ntau tsis yog noj, kev noj khoom haus tsis huv yuav ua rau mob plab zom mov.
3. Kev tswj hwm cov xwm txheej: TereSphthalic acid tsis tau cais raws li Carcinogen lossis kev nyab xeeb cov ntaub ntawv kev nyab xeeb los ntawm kev nyab xeeb ntawm kev tswj hwm kev noj qab haus huv thiab cov lus qhia raug cai.
4. Ib puag ncig cuam tshuam: txawm hais tias Terephthalic acid tsis ua rau raug mob rau tib neeg lub cev, yog tias nws tau tshaj tawm nyob rau ib puag ncig, yog li tsis ncaj rau tib neeg kev noj qab haus huv.
Thaum thauj TereCthalic acid, nws yog ib qho tseem ceeb kom ua kev ceev faj kom meej thiab ua raws li kev nyab xeeb. Nov yog qee qhov kev txiav txim siab tseem ceeb los coj mus rau hauv tus account:
1. Ntim: Siv cov thawv tsim nyog uas tau tshaj nrog Terephthalic acid. Feem ntau, nws yuav tsum tau muab cia rau hauv cov ntim, daim ntawv lo ntim ua los ntawm cov ntaub ntawv uas tsis hnov mob nrog cov kua qaub.
2. Daim ntawv lo: Daim ntawv qhia meej tag nrho cov npe siv tshuaj, cov cim phom sij thiab cov lus qhia kev phom sij. Xyuas kom meej tus sau npe ua raws li cov kev cai hauv zos thiab thoob ntiaj teb.
3. Kev thauj mus los ntawm kev thauj mus los: Ua raws kev cai thauj mus los, xws li Asmeskas Lub Tsev Haujlwm Kev Thauj Mus Los (DOT) lossis kev thauj mus los. Terephthalic acid tsis feem feem ntau cais ua kev txaus ntshai zoo, tab sis nws yog ib qho tseem ceeb kom kuaj xyuas tshwj xeeb cov cai.
4. Kev ntsuas kub: Khw thiab thauj Terephthalic acid nyob rau hauv qhov chaw txias thiab qhuav los tiv thaiv kev ua kom muaj kev cuam tshuam lossis kev tawm tsam nrog noo noo.
5
6. Cov cuab yeej tiv thaiv tus kheej (PPE): Xyuas kom cov neeg ua haujlwm tuav cov kev thauj khoom uas tsim nyog ppe, xws li hnab looj tes uas tsim nyog hnav PPE, xws li hnab looj tes thiab goosgles, kom tiv thaiv daim tawv nqaij thiab qhov muag.
7. Cov txheej txheem thaum muaj xwm ceev: Thaum muaj tej yam nchuav lossis txeej thaum thauj khoom, txhim kho cov txheej txheem thaum muaj xwm txheej ceev. Qhov no suav nrog kev muaj cov khoom siv spill thiab cov khoom siv ua ntej npaj.
8. Cov ntaub ntawv: tswj cov ntaub ntawv xa khoom kom tsim nyog, suav nrog cov ntawv txheeb xyuas kev nyab xeeb (SDS) thiab ib qho uas yuav tsum tau tso cai lossis tshaj tawm.
