Sodium hydroxide hiav txwv xa tawm txheej txheem thiab kev ceev faj

Sodium hydroxide, tseem hu ua caustic soda thiab caustic soda, tshuaj mis yog NaOH, yog ib yam muaj zog alkali uas muaj kev sib txhuam siab, feem ntau yog cov hmoov dawb los yog cov hmoov, tuaj yeem yaj hauv dej los tsim cov tshuaj alkaline, kuj tuaj yeem yaj hauv methanol thiab ethanol. Sodium hydroxide muaj deliquescence, uas tuaj yeem nqus cov pa dej hauv huab cua, thiab tseem nqus cov pa roj av xws li carbon dioxide thiab sulfur dioxide.

Xwm

Sodium hydroxide yog tshuaj hnyav heev, tawv lossis nws cov tshuaj tuaj yeem hlawv tawv nqaij, uas tuaj yeem ua rau raug mob tas li (xws li caws pliav) rau cov uas tsis muaj kev tiv thaiv. Yog tias sodium hydroxide raug rau lub qhov muag ncaj qha, qhov hnyav tuaj yeem ua rau dig muag. Kev tiv thaiv tus kheej, xws li hnab looj tes roj hmab, tiv thaiv khaub ncaws thiab tsom iav, tuaj yeem txo qis kev pheej hmoo ntawm kev sib cuag nrog sodium hydroxide

Lub Hom Phiaj

Sodium hydroxide tau siv dav. Nws yog siv hauv kev tsim cov ntawv, xab npum, zas xim, paj rwb, ua kom cov roj ua kom tiav, paj rwb ua tiav, cov khoom siv roj ua kom huv, ua zaub mov noj, ua ntoo thiab tshuab kev lag luam.

Sodium hydroxide tau siv dav hauv kev lag luam hauv tebchaws, ntau lub lag luam xav tau sodium hydroxide. Cov haujlwm uas siv sodium hydroxide feem ntau yog kev tsim tshuaj lom neeg, ua raws los ntawm kev ua papermaking, aluminium smelting, tungsten smelting, rayon, artificial paj rwb thiab xab npum tsim. Ib qho ntxiv, hauv kev tsim cov xim, plastics, tshuaj lom neeg thiab cov tshuaj nruab nrab nruab nrab, kev rov tsim dua cov roj hmab qub, kev siv hluav taws xob ntawm cov hlau sodium thiab dej, thiab tsim cov ntsev tsis haum, ntau npaum li cas ntawm cov dej qab ntsev yog siv hauv kev tsim khoom borax, chromate, manganate, phosphate, thiab lwm yam. tib lub sijhawm, sodium hydroxide yog ib qho tseem ceeb ntawm cov khoom siv raw rau kev tsim cov polycarbonate, super nqus cov polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite thiab ntau tus sodium ntsev

Kev Thauj Mus Los Hauv Av

Ua ntej tshaj plaws, lub hauv paus tsis tuaj yeem thauj hauv aluminium lossis zinc poom, vim tias sodium hydroxide yog lub hauv paus muaj zog, thiab nws cov tshuaj yuav ua haujlwm nrog txhuas thiab zinc ua cov pa roj carbon, sodium metaaluminate lossis sodium metazincate

Qhov thib ob, foob thiab sau! Vim tias yog muaj huab cua, sodium hydroxide yuav tsis zoo! Sodium carbonate thiab dej tau tsim

Qhov thib peb, ua ntej yaug cov nitrogen, oxygen thiab lwm cov pa tiv thaiv mus rau hauv lub tank, tso cua kom ntau li ntau tau, tom qab ntawd ntxiv cov tshuaj sodium hydroxide, maj mam tso cov pa tiv thaiv, thiab tom qab ntawd kaw lub tsheb thauj mus los.

Ceev faj Txog Sodium Hydroxide Export Los Ntawm Hiav Txwv

Cov ntaub ntawv rau sodium hydroxide xa los ntawm hiav txwv

1. Phau ntawv
Kev xaj lub hwj chim ntawm kws lij choj: ntxiv rau tus neeg xa khoom thiab tus neeg xa khoom cov ntaub ntawv, qhov tseem ceeb tshaj plaws yog kom piav qhia meej txog qhov hnyav tag nrho, qhov hnyav, cov ntawv ntim thiab ntim sab hauv ntawm ib qho
(Nco ntsoov tias cov ntawv xa khoom phom sij yuav tsum tau ua kaum hnub ua ntej. Cov ntaub ntawv xaj khoom txaus ntshai yuav tsum raug thiab tsis tuaj yeem hloov pauv.)

2.MSDS ua lus Askiv
MSDS (tus tswv nkoj yuav tsom mus rau lub cev thiab tshuaj lom neeg thiab cov khoom thauj, uas txiav txim siab qhov xwm txheej ntawm tus tswv nkoj. Lawv yuav ib txwm paub yuav ua li cas tsom mus rau kev ua haujlwm hauv kev thauj mus los)
Nco tseg: sodium hydroxide belongs rau qeb 8 cov khoom phom sij, UN 1823, qeb II txaus ntshai pob ntawv pov thawj daim ntawv tshaj tawm daim ntawv

Nrog lub hwj chim ntawm kws lij choj thiab MSDS, koj tuaj yeem sau cov khoom lag luam txaus ntshai. Feem ntau ob hnub ua haujlwm tuaj yeem faib tau.

3.Cov ntawv pov thawj txaus ntshai
(nws feem ntau suav nrog daim ntawv ua haujlwm thiab daim ntawv pov thawj siv. Daim ntawv ua haujlwm tau yooj yim thiab tuaj yeem muab los ntawm cov tuam ntxhab uas tuaj yeem ua ntim khoom ib txwm muaj. Lub chaw haujlwm ntawm lub koomhaum thov nrog IMI kev txheeb xyuas thiab daim ntawv ua haujlwm.)

4.Txhua yam khoom lag luam tshaj tawm
Cov kauj ruam tom ntej yog tshaj tawm cov khoom txaus ntshai. Raws li qhov xav tau ntawm cov tuam txhab thauj khoom sib txawv thiab cov neeg xa khoom xa tuaj, cov ntaub ntawv tshaj tawm tuaj yeem xa tuaj raws li hnub kawg ua ntej tshaj tawm. Kev tshaj tawm cov khoom phom sij feem ntau yog los tshuaj xyuas pob, yog li ntawv tseem ceeb tshaj plaws yog daim ntawv pov thawj khoom txaus ntshai.
Cov ntaub ntawv tshaj tawm txaus ntshai: thawj daim ntawv pov thawj phom sij txaus ntshai, Lus Askiv MSDS, daim ntawv ntim khoom, ntim daim ntawv pov thawj, ntawv tshaj tawm txoj cai ntawm kws lij choj

5.Kev npaj rau kev thauj mus los thiab ntim khoom yog ib qho tseem ceeb
Qhov txuas no tuaj yeem faib ua ob hom kev ua haujlwm: chaw thau khoom chaw thau khoom thiab lub rooj vag Lub Hoobkas Point Trailer
Yog tias nws tau ntim rau hauv lub tsev rau khoom, koj yuav tsum ua daim ntawv ceeb toom nkag mus rau lub tsev cog khoom kom paub meej tias lub sijhawm xa khoom mus rau lub tsev rau khoom nrog tus neeg siv khoom
Yog tias lub tsev qhov rooj taw tes trailer tau siv, nws yuav tsum tau thauj los ntawm lub nkoj nrog cov khoom tsim nyog. Tus tsav tsheb yuav tsum yog tus paub dhau los ntawm kev tsav tsheb txaus ntshai, uas tuaj yeem nyab xeeb thiab ua tiav lub sijhawm thauj khoom.

6. Tshaj tawm ntawm kev lis kev cai
Ntxiv rau cov ntaub ntawv tshaj tawm kev lis kev cai niaj hnub, nws tseem yuav tsum tau sau tseg tias sodium hydroxide yog cov khoom lag luam raug tshuaj xyuas raws cai, thiab kev tshuaj xyuas cov khoom lag luam yuav tsum tau muab rau kev xa tawm hiav txwv.

7.Txoj kev nqa khoom
Tom qab lub nkoj tawm mus, nqa daim nqi nqa khoom rau kev them nyiaj, lees paub nrog tus neeg xa khoom seb puas yuav xa daim nqi nqa khoom qub lossis xov tooj xa xov xa tawm ntawm cov khoom nqa, thiab npaj kev lis kev lis kev cai thiab xa tom qab lub nkoj tuaj txog ntawm qhov chaw nres nkoj.
Sodium hydroxide belongs rau 8 yam khoom txaus ntshai, uas tuaj yeem xa tawm los ntawm LCL. Txawm li cas los xij, nws yuav tsum tau sau tseg tias nws tsis tuaj yeem sib xyaw nrog 4 yam khoom phom sij lossis cov kua qaub, thiab yuav tsum ua raws nruj raws li qhov yuav tsum tau khaws thiab cais cov khoom txaus ntshai los ntawm LCL.
