Hauv kev txiav txim siab yuav khoom hauvkev lag luam chemical, cov qauv ntim tshuaj lom neeg yog ib qho tseem ceeb rau cov neeg yuav khoom. Tsim nyog ntim tsim thiab xaiv cov khoom siv tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov khoom, tab sis kuj txo cov nqi thauj mus los thiab khaws cia. Kab lus no yuav piav qhia ntxaws ntxaws txog cov qauv ntim tshuaj uas cov neeg yuav khoom yuav tsum nkag siab los ntawm peb yam: xaiv cov khoom ntim, cov ntawv cim npe, thiab cov qauv tsim thiab kev thauj mus los.
Xaiv cov khoom ntim
Thaum xaiv cov khoom ntim tshuaj, qhov kev txiav txim siab tseem ceeb yog cov tshuaj sib xyaw ua ke ntawm cov khoom. Cov tshuaj sib txawv muaj qhov sib txawv rau cov khoom ntim khoom. Piv txwv li, cov tshuaj lom neeg muaj kev phom sij yuav xav tau lub raj mis iav, thaum cov tshuaj ua kuab tshuaj zoo tib yam tsim nyog rau lub raj mis yas lossis cov kaus poom hlau. Cov iav fwj muaj qhov zoo ntawm cov tshuaj lom neeg tsis zoo thiab tsis tso cov tshuaj phem. Txawm li cas los xij, lawv qhov tsis zoo suav nrog cov nqi siab dua thiab qhov yuav tsum tau ntim tshwj xeeb thaum thauj mus los los tiv thaiv kev tawg. Lub raj mis yas yog tus nqi qis dua, yooj yim rau kev khiav lag luam thiab kev thauj mus los, tab sis cov yas zoo li adsorb tshuaj, thiab kev cia ntev ntev yuav ua rau muaj kuab paug ib puag ncig. Cov kaus poom hlau muaj qhov zoo corrosion kuj thiab sealing kev ua tau zoo, ua rau lawv haum rau cov tshuaj uas yooj yim soluble los yog reactive heev, tab sis lawv cov nqi ntau lawm kuj siab.
Qhov kub tsis kam ntawm cov khoom ntim kuj yog ib qho tseem ceeb rau kev txiav txim siab. Hauv kev tsim tshuaj lom neeg, cov tshuaj feem ntau yuav tsum tau khaws cia thiab thauj mus rau hauv qhov kub thiab txias. High-melting-point iav fwj thiab cov kaus poom hlau tuaj yeem siv tau ntawm qhov kub thiab txias, thaum lub raj mis yas yog qhov ua rau deformation thiab tsis haum rau qhov kub thiab txias. Kev rov ua dua tshiab thiab kev ua phooj ywg ib puag ncig ntawm cov khoom ntim kuj tseem ceeb rau cov neeg yuav khoom niaj hnub no; xaiv cov ntaub ntawv zoo ib puag ncig tuaj yeem txo lub nra ntawm ib puag ncig.
Labels thiab Markings
Cov ntawv sau rau ntawm cov tshuaj ntim tshuaj yuav tsum muaj ntau yam ntaub ntawv tseem ceeb los xyuas kom meej cov khoom muaj kev nyab xeeb thiab kev taug qab. Raws li International Chemical Safety Labeling Standard (ITIS), cov ntawv sau yuav tsum muaj cov ntaub ntawv xws li tshuaj lub npe, kev faib tawm, cov khoom txaus ntshai, cov xwm txheej khaws cia, thiab daim ntawv tso cai ntau lawm. Hauv kev ua lag luam Suav, cov ntawv sau tshuaj yuav tsum ua raws li cov cai hauv lub tebchaws ntawm kev nyab xeeb tshuaj, nrog cov ntsiab lus ntxaws ntxiv nrog rau kev faib tawm, kev siv, kev cia khoom, thiab cov lus qhia rau kev sib cuag thaum muaj xwm ceev.
Qhov tseeb thiab qhov tseeb ntawm cov ntawv thiab cov cim yog qhov tseem ceeb rau cov neeg yuav khoom txiav txim siab. Yog tias cov ntaub ntawv sau npe tsis tiav lossis tsis meej, cov neeg yuav khoom yuav tsis tuaj yeem txheeb xyuas cov khoom muaj kev nyab xeeb thiab khaws cia. Cov font thiab cov ntsiab lus layout ntawm daim ntawv lo yuav tsum ua raws li cov qauv kev cai kom ntseeg tau tias cov neeg nyeem tuaj yeem nkag siab cov ntsiab lus ntawm daim ntawv lo.
Ntim tsim thiab kev thauj mus los
Ntim tsim yog qhov txuas tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm kev thauj mus los ntawm cov tshuaj. Leak-proof tsim tuaj yeem tiv thaiv kom tsis txhob ntim khoom los ntawm kev xau thaum thauj, tiv thaiv kev nyab xeeb ntawm cov khoom. Cov ntaub ntawv pov thawj tsim nyog yog tsim rau khaws cia thiab thauj cov dej noo-absorbing lossis oxidizable chemicals, uas tuaj yeem siv cov txheej txheem ya raws lossis cov ntaub ntawv tshwj xeeb. Kev tsim cov ntaub ntawv pov thawj muaj peev xwm ua rau muaj kev vibrations thaum lub sijhawm thauj mus los, siv cov ntaub ntawv nyuaj thiab cov qauv kaw.
Hais txog kev thauj mus los, cov tshuaj sib txawv muaj cov ntim sib txawv thiab cov qauv kev thauj mus los. Cov tshuaj phom sij yuav tsum tau ntim tshwj xeeb thiab cov ntawv lo, nrog rau cov ntaub nplaum los tiv thaiv thiab tiv thaiv kev sib tsoo thaum lub sijhawm thauj mus los. Flammable lossis explosive chemicals xav tau kev ntim tshwj xeeb tsim thiab tuav cov lus qhia. Thaum lub sij hawm kev thauj mus los, cov ntaub ntawv ntim thiab cov ntawv yuav tsum nyob twj ywm kom ntseeg tau tias cov ntaub ntawv tsis ploj thaum tau txais.
Cov ntsiab lus
Cov qauv ntim tshuaj lom neeg yog lub hauv paus tseem ceeb rau cov neeg yuav khoom hauv kev lag luam tshuaj thaum xaiv cov khoom ntim thiab cov ntawv lo. Kev xaiv cov khoom ntim tsim nyog tsis yog tsuas yog cuam tshuam txog kev nyab xeeb ntawm cov khoom, tab sis kuj cuam tshuam rau kev thauj mus los thiab cov nqi khaws cia. Qhov tseeb thiab qhov tseeb ntawm daim ntawv lo thiab cov cim yog qhov tseem ceeb rau cov neeg yuav khoom txog kev ntim khoom zoo. Los ntawm kev nkag siab tob txog cov txheej txheem ntim tshuaj, cov neeg yuav khoom tuaj yeem txiav txim siab txog kev yuav khoom, ua kom muaj kev nyab xeeb thiab ua raws li cov khoom lag luam thoob plaws hauv lawv lub neej.
