    CHEMICAL PROPERTIES

    Methylene chloride reacts muaj zog nrog cov hlau nquag xws li potassium, sodium, thiab lithium, thiab cov hauv paus muaj zog, piv txwv li, potassium tert-butoxide.Txawm li cas los xij, qhov sib xyaw ua ke tsis sib haum nrog muaj zog caustics, muaj zog oxidizers, thiab hlau uas muaj tshuaj lom neeg xws li magnesium thiab txhuas hmoov.

    Nws yog ib qho tseem ceeb uas methylene chloride tuaj yeem tua qee hom txheej, yas, thiab roj hmab.Tsis tas li ntawd, dichloromethane reacts nrog kua oxygen, sodium-potassium alloy, thiab nitrogen tetroxide.Thaum cov khoom sib txuas nrog dej, nws corrodes ib co stainless hlau, npib tsib xee, tooj liab thiab hlau.
    Thaum raug tshav kub los yog dej, dichloromethane ua rhiab heev vim nws raug hydrolysis uas yog ceev los ntawm lub teeb.Raws li ib txwm muaj, cov kev daws teeb meem ntawm DCM xws li acetone lossis ethanol yuav tsum ruaj khov rau 24 teev.

    Methylene chloride tsis hnov ​​​​mob nrog alkali hlau, zinc, amines, magnesium, nrog rau cov alloys ntawm zinc thiab txhuas.Thaum sib xyaw nrog nitric acid los yog dinitrogen pentoxide, lub compound tuaj yeem tawg heev.Methylene chloride yog flammable thaum tov nrog methanol vapor hauv huab cua.

    Txij li thaum lub compound tuaj yeem tawg, nws yog ib qho tseem ceeb kom tsis txhob muaj tej yam mob xws li sparks, kub qhov chaw, qhib nplaim taws, tshav kub, static paug, thiab lwm yam ignition qhov chaw.

    APPLICATION AREA

    Cov Khoom Siv Hauv Tsev
    Lub compound yog siv nyob rau hauv da dej refurbishing.Dichloromethane yog siv dav hauv kev tsim cov tshuaj, strippers, thiab cov txheej txheem cov kuab tshuaj.
    Kev lag luam thiab kev tsim khoom siv
    DCM yog cov kuab tshuaj uas muaj nyob rau hauv cov kua roj vanish thiab xim strippers, uas feem ntau yog siv los tshem tawm cov kua roj vanish lossis xim txheej los ntawm ntau qhov chaw.Raws li cov kuab tshuaj hauv kev lag luam tshuaj, DCM yog siv rau kev npaj ntawm cephalosporin thiab ampicillin.

    Khoom noj khoom haus thiab dej haus Manufacturing
    Nws kuj tseem siv rau hauv kev tsim dej haus thiab khoom noj khoom haus raws li cov kuab tshuaj extraction.Piv txwv li, DCM tuaj yeem siv los decaffeinate unroasted kas fes taum nrog rau tshuaj yej nplooj.Lub compound kuj yog siv los tsim hops extract rau npias, dej haus thiab lwm yam flavoring rau zaub mov, nrog rau kev ua txuj lom.

    Kev lag luam tsheb thauj mus los
    DCM feem ntau yog siv rau hauv degreasing ntawm cov hlau qhov chaw thiab qhov chaw, xws li cov khoom siv tsheb ciav hlau thiab cov lem thiab cov khoom siv dav hlau.Nws tseem tuaj yeem siv rau hauv degreasing thiab lubricating cov khoom siv hauv cov khoom siv tsheb, piv txwv li, tshem tawm cov gasket thiab npaj cov khoom siv hlau rau lub gasket tshiab.
    Cov kws tshaj lij hauv tsheb feem ntau siv cov txheej txheem vapor dichloromethane degreasing rau kev tshem tawm cov roj thiab roj los ntawm lub tsheb qhov chaw ntawm lub tsheb transistor, spacecraft assemblies, aircraft Cheebtsam, thiab diesel motors.Niaj hnub no, cov kws tshaj lij muaj peev xwm ua kom muaj kev nyab xeeb thiab huv si sai sai siv cov txheej txheem degreasing uas nyob ntawm methylene chloride.

    Kev lag luam kho mob
    Dichloromethane yog siv nyob rau hauv lub chaw soj nstuam nyob rau hauv lub extraction ntawm cov tshuaj los ntawm cov khoom noj los yog cov nroj tsuag rau cov tshuaj xws li tshuaj tua kab mob, steroids, thiab vitamins.Tsis tas li ntawd, cov cuab yeej siv kho mob tuaj yeem ua tau zoo thiab ntxuav sai sai siv cov tshuaj ntxuav dichloromethane thaum tsis txhob muaj kev puas tsuaj rau qhov kub thiab txias thiab teeb meem corrosion.

    Cov duab thaij duab
    Methylene chloride yog siv los ua ib qho hnyav hauv kev tsim cov cellulose triacetate (CTA), uas yog siv rau hauv kev tsim cov yeeb yaj kiab kev nyab xeeb hauv kev yees duab.Thaum yaj hauv DCM, CTA pib evaporate raws li cov fiber ntau ntawm acetate tseem nyob tom qab.

    Kev lag luam hluav taws xob
    Methylene chloride yog siv rau hauv kev tsim cov ntawv luam tawm Circuit Court boards hauv kev lag luam hluav taws xob.DCM yog siv los degrease cov ntawv ci ntawm lub substrate ua ntej cov txheej txheem photoresist ntxiv rau lub rooj tsavxwm.

    YUAV UA LI CAS LOS NTAWM US

    Chemwin tuaj yeem muab ntau hom hydrocarbons thiab cov kuab tshuaj tshuaj lom neeg rau cov neeg siv khoom.Ua ntej ntawd, thov nyeem cov lus qhia hauv qab no txog kev ua lag luam nrog peb: 

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws.Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv ntawm peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias qhov kev pheej hmoo ntawm kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis rau qhov tsim nyog thiab ua tau tsawg kawg nkaus.Yog li ntawd, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no).Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.
