Khoom molecular qauv
Methylene chloride reacts muaj zog nrog cov khoom siv hlau xws li potassium, sodium, thiab Lithcacy, thiab muaj zog, potassium tert-butoxide. Txawm li cas los xij, cov compound yog incompatibatibatibatibatibatibatibat phim, muaj zog oxidizers, thiab cov hlau uas yog cov tshuaj muaj tshuaj xws li cov hmoov magnesium thiab txhuas.
Nws yog qhov tsis tseem ceeb uas methylene chloride tuaj yeem tua qee hom kev pleev xim, yas, thiab roj hmab. Ib qho ntxiv, dichloromethane reacts nrog cov pa oxygen, sodium-potassium alloy, thiab nitrogen tetroxide. Thaum cov kab sib txuas los rau hauv kev sib cuag nrog dej, nws corrodes ib co hlau hlau, npib tsib xee, tooj liab thiab hlau.
Thaum raug cua sov los yog dej, dichloromethane yuav rhiab heev raws li nws yog raug rau hydrolysis uas nrawm nrawm ntawm lub teeb. Nyob rau hauv ib txwm muaj mob, kev daws teeb meem ntawm dcm xws li acetone lossis ethanol yuav tsum ruaj khov rau 24 teev.
Methylene chloride tsis hnov qab zib nrog cov makali metrals, zinc, amines, magnesium, ntxiv rau alloys ntawm zinc thiab txhuas. Thaum sib xyaw nrog nitric acid lossis dinitrogen pentoxide, qhov sib txuas tuaj yeem ua rau tawg. Methylene chloride yog nplaim taws thaum sib xyaw nrog Methanol vapor hauv huab cua.
Txij li thaum lub compound tuaj yeem tawg, nws yog ib qho tseem ceeb kom zam qee yam mob xws li cov kab hluav taws, kub tawm, cua sov, thiab lwm yam kev tawm tsam.
Lub tsev tuav siv
Cov compound yog siv hauv dab da dej. Dichhloromethane yog cov siv tau zoo heev hauv kev tsim cov tshuaj paus, cov hlua, thiab cov kuab tshuaj.
Kev lag luam thiab kev tsim khoom siv
DCM yog qhov tseeb uas pom nyob hauv cov kua roj varnish thiab xim pleev xim, uas feem ntau siv los tshem cov kua roj vanish lossis xim pleev xim los ntawm ntau qhov chaw. Raws li cov kuab tshuaj hauv kev lag luam kws tshuaj, DCM yog siv rau kev npaj ntawm Cepharosporin thiab Ampicillin thiab Ampicillin.
Khoom Noj Thiab Dej Haus Raug
Nws tseem siv rau hauv kev tsim khoom haus thiab khoom noj ua khoom lag luam raws li cov kuab hnyav. Piv txwv li, DCM tuaj yeem siv rau cov quav ntsev tsis muaj kev txwv tsis ntev li cov nplooj tshuaj yej. Qhov sib xyaw kuj tseem siv rau hauv kev tsim cov hops extract rau npias, dej haus thiab lwm yam tsw rau cov zaub mov, thiab ua cov tshuaj lom neeg.
Kev Lag Luam Tsheb thauj mus los
DCM feem ntau yog siv nyob rau hauv cov khoom ntawm cov hlau thiab thaj chaw, xws li cov cuab yeej kev tsheb ciav hlau thiab cov ciav hlau ib yam li dav hlau. Nws kuj tseem siv tau rau hauv cov khoom lag luam degroging thiab lubricating siv hauv cov khoom lag luam Automotive, piv txwv li cov gasket thiab rau kev npaj cov khoom hlau rau cov gasket hlau tshiab.
Cov kws tshaj lij hauv automotive feem ntau siv vapor dihloromiatias dichate ua rau kev tshem tawm ntawm cov roj trancease thiab cov pa hluav taws xob, cov dav hlau sib dhos, thiab cov roj ntsha motors. Niaj hnub no, cov kws tshaj lij tshwj xeeb tuaj yeem muaj kev thauj mus los nyab xeeb thiab nrawm nrawm nrawm siv cov tswv yim kom tsawg uas vam khom mehloride.
Kev Lag Luam Kho Mob
Dichhloromethane yog siv nyob rau hauv extraction ntawm cov tshuaj lom neeg los ntawm cov zaub mov los yog cov nroj tsuag rau tshuaj tua kab mob, tshuaj steribians, thiab vitamins. Ib qho ntxiv, cov khoom siv kho mob tuaj yeem ua tau zoo thiab nrawm nrawm nrawm thaum tsis txhob muaj kev puas tsuaj rau cov teeb meem kub thiab cov teeb meem corrosion.
Duab Zaj Duab Xis
Methylene chloride yog siv los ua cov kuab tshuaj nyob rau hauv kev tsim cov cellulose triacetate (CTA), uas yog thov rau hauv kev tsim cov yeeb yaj kiab kev nyab xeeb hauv kev yees duab. Thaum yaj nyob rau hauv DCM, CTA pib kiab li cov fiber ntau ntawm acetate tseem tshuav qab.
Kev lag luam hluav taws xob
Methylene chloride yog siv nyob rau hauv kev tsim cov ntawv luam tawm cov board hauv kev lag luam hluav taws xob. DCM yog siv los ua kom haum cov ntawv nyiaj ntawm lub substrate ua ntej txheej photoresist tau ntxiv rau lub rooj tsavxwm.
Chemwin tuaj yeem muab ntau qhov ntau ntawm hydrocarbons thiab cov kuab tshuaj lom neeg rau cov neeg siv khoom lag luam.Ua ntej ntawd, thov nyeem cov ntaub ntawv hauv qab no hais txog kev ua lag luam nrog peb:
1. Kev ruaj ntseg
Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws. Ntxiv rau muab cov neeg siv khoom nrog kev siv cov ntaub ntawv hais txog peb cov khoom lag luam, peb kuj tau cog lus tias kev muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis thiab ua tau tsawg kawg nkaus. Yog li ntawd, peb xav kom tus qhua tuaj noj mov kom ntseeg tau tias qhov tsim nyog tso tseg thiab kev nyab xeeb cov qauv kev nyab xeeb tau ntsib cov ntawv tshaj tawm HSSE (thov saib cov nqe lus dav dav thiab cov ntsiab lus ntawm kev muag khoom hauv qab). Peb cov kws paub HDSE tau muab cov kev taw qhia rau cov qauv no.
2. Kev Xa Tawm
Cov neeg siv khoom tuaj yeem xaj thiab xa cov khoom lag luam los ntawm Chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov khoom lag luam tsim khoom. Cov qauv muaj kev thauj khoom muaj cov tsheb thauj neeg muaj tsheb thauj khoom, tsheb ciav hlau lossis cov neeg thauj khoom ntau (cais cov mob siv).
Nyob rau hauv cov ntaub ntawv uas cov neeg yuav tsum tau ua, peb tuaj yeem hais cov cai ntawm cov nkoj lossis cov qauv kev nyab xeeb thiab siv cov qauv kev nyab xeeb tshwj xeeb / tshuaj xyuas thiab cov tseev kom ua.
3. Yam tsawg kawg txiav txim kom muaj nuj nqis
Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.
4. Upayment
Txoj kev them nqi them yog ncaj qha txiav tawm tsis pub dhau 30 hnub los ntawm daim ntawv qhia nqe.
5. Xa cov ntaub ntawv
Cov ntaub ntawv hauv qab no tau muab rau txhua qhov kev xa khoom:
Bill Nqi ntawm Lading, Cmr Waybill lossis lwm daim ntawv thauj khoom uas muaj feem xyuam
Daim ntawv pov thawj ntawm kev ntsuas lossis kev ua raws (yog tias yuav tsum tau)
