Vim li cas Dichloromethane (DCM) siv rau hauv Paint Strippers? Kev siv thiab kev xav txog kev nyab xeeb

Tau ntau xyoo lawm, Dichloromethane lossis methylene chloride tau raug suav tias yog ib qho ntawm cov kuab tshuaj zoo tshaj plaws rau kev tshem tawm cov xim thiab txheej txheej stripping daim ntaub ntawv. Nws qhov kev ua tau sai thiab kev sib raug zoo nrog cov txheej txheem txheej txheej ua rau nws nyiam xaiv thoob plaws kev lag luam. Txawm li cas los xij, kev pheej hmoo ntawm kev noj qab haus huv tseem ceeb thiab cov kev cai nruj ntxiv tau txo nws txoj kev siv ntau. Txawm hais tias koj yog tus thawj tswj hwm kev lag luam, tus kws tsim khoom tsim khoom, lossis tsuas yog tshawb nrhiav cov kev cai hnyav, phau ntawv qhia no piav qhia vim li cas DCM tau siv dav heev, muaj kev pheej hmoo cuam tshuam, thiab lwm yam uas muaj nyob rau niaj hnub no.

•  Yam khoom: Muaj Qib Dichloromethane (DCM) / Methylene Chloride CAS 75-09-2 High-Purity Solvent

CAS No.75-09-2 Dichloromethaneua haujlwm zoo li cov xim stripper vim muaj ntau lub cev thiab tshuaj lom neeg ntsuas. Nws muaj qhov me me me me, qhov nruab nrab polarity, qis kub taw tes, thiab muaj zog muaj peev xwm nkag mus thiab o ntau cov yeeb yaj kiab polymer. Cov khoom no cia nws txav mus rau hauv txheej txheej, ua kom tsis muaj zog ntawm cov xim thiab cov substrate, thiab pab lub txheej tshem tawm.

Key Performance Advantages

1. Ceev ceev

Methylene Chloride muaj qhov kub ntawm qhov kub ntawm 39.6℃thiab lub siab vapor siab ntawm chav tsev kub, yog li nws evaporates sai thiab tuaj yeem mloog zoo ntawm cov txheej txheej thaum siv. Nyob rau tib lub sijhawm, nws cov kuab tshuaj ua haujlwm pib sai li sai tau thaum nws hu rau cov xim zaj duab xis, ntau cov coatings pib muag hauv 15-30 feeb. Los ntawm kev sib piv, benzyl cawv thiab dibasic ester formulations feem ntau muaj cov ntsiab lus kub siab dua thiab qis dua cov evaporation, yog li lawv feem ntau xav tau ob peb teev ua haujlwm los ntawm tib txheej txheej.

2. Ntau-Txheej txheej nkag

Dichloromethane DCM molecules yog me me thiab muaj viscosity tsawg, uas tso cai rau lawv txav mus los ntawm cov kab nrib pleb, qhov hws, thiab cov npoo hauv cov hnub nyoog xim xim. Thaum nyob rau hauv cov txheej txheej, nws tuaj yeem sib txawv ntawm cov khaubncaws sab nraud povtseg thiab o ntawm lub network polymer. Qhov o tuaj yeem txo qhov adhesion ntawm cov khaubncaws sab nraud povtseg thiab nruab nrab ntawm txheej thiab substrate, yog li ob peb txheej tuaj yeem loosen tib lub sijhawm.

3. Kev sib tw dav

DCM tshuaj tuaj yeem tshem tawm ntau hom txheej txheej vim tias nws tuaj yeem cuam tshuam nrog ntau yam ntawm cov kab ke, suav nrog:

• Polyurethane txheej
• Epoxy txheej
• Alkyd xim
• Cov xim acrylic
• Lacquers
• Cov roj tsoos -raws li txheej

Qhov no ua haujlwm vim tias DCM (CAS 75-09-2) muaj qhov hnyav polarity uas tso cai rau nws kom yaj lossis o ntau cov organic binders siv hauv cov xim thiab cov khoom tiav. Coatings nrog cov qauv resin sib txawv teb txawv, tab sis DCM tuaj yeem cuam tshuam rau ntau yam ntawm lawv ntau dua li ntau cov kuab tshuaj ib leeg.

4. Tsawg viscosity thiab siab volatility

DCM kua muaj viscosity tsawg, yog li nws tuaj yeem ntws mus rau cov ncauj lus kom ntxaws, seams, fab, thiab lwm yam nyuaj - mus rau - mus txog thaj chaw. Nws kuj muaj qhov tsis muaj zog, uas txhais tau tias nws evaporates sai sai tom qab thov.

5. Tsis yog-Cov yam ntxwv ntawm cov nplaim taws

Methylene chloride tsis ignite yooj yim nyob rau hauv ib txwm tej yam kev mob vim hais tias nws muaj ib tug high vapor ceev thiab tsis txhawb combustion li ntau hydrocarbon solvents ua.

Txawm hais tias nws qhov kev ua tau zoo, DCM nthuav tawm cov teeb meem kev noj qab haus huv tseem ceeb uas thaum kawg coj cov neeg tswj hwm thoob ntiaj teb txwv tsis pub siv.

1. Mob toxicity:

Ib qho tseem ceeb tshaj plaws ntawm DCM raug yog tias tib neeg lub cev metabolizes ib feem ntawm cov kuab tshuaj absorbed rau hauv carbon monoxide.
Qhov no ua rau muaj ntau yam xwm txheej tshwj xeeb:

• Kev raug yuav tsis tuaj yeem ua rau muaj kev ceeb toom muaj zog.
• Kev tsim cov pa roj carbon monoxide tuaj yeem txo cov ntshav oxygen - nqa lub peev xwm.
• Cov tsos mob yuav muaj xws li kiv taub hau, mob taub hau, tsis meej pem, xeev siab, thiab kev sib koom tes tsis zoo.
• Kev raug mob ntau tuaj yeem ua rau tsis nco qab, ua pa nyuaj, mob plawv, thiab tuag.
• Cov kab mob tuag taus tau raug tshaj tawm nyob rau hauv qhov chaw tsis zoo thiab qhov chaw kaw, qee zaum tshwm sim hauv lub sijhawm luv luv tom qab kis tau.

Cov koom haum saib xyuas kev noj qab haus huv hauv Asmeskas tau sau txog kaum ob tus neeg tuag uas cuam tshuam nrog methylene chloride- muaj cov xim pleev xim, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaw - daim ntawv thov xws li da dej refinishing thiab kev lag luam tu.

2. Cov teebmeem kev noj qab haus huv ntev

Kev rov ua dua lossis ntev ntev - raug cuam tshuam nrog:

• Lub siab toxicityNeurological teebmeem
• Kev paub tsis meej
• Cov tawv nqaij khaus thiab dermatitis
• Kev ntxhov siab hauv plawv ntau ntxiv vim muaj cov pa roj carbon monoxide

Ntau lub koom haum tswj hwm, suav nrog US EPA thiab cov koom haum saib xyuas kev noj qab haus huv thoob ntiaj teb, faib cov tshuaj methylene chloride raws li qhov muaj peev xwm lossis qhov tshwm sim ntawm tib neeg carcinogen raws li cov pov thawj muaj.
Cov neeg ua haujlwm koom nrog hauv kev pleev xim, kho cov rooj tog zaum, thiab kev saib xyuas kev lag luam yav dhau los tau ntsib cov neeg ua haujlwm siab tshaj plaws.

Hauv Tebchaws Meskas, dichloromethane tseem tuaj yeem siv tau tsuas yog hauv kev txwv, kev tswj hwm kev siv qee yam xws li aerospace, kev tiv thaiv, chav kuaj, thiab kaw-cov haujlwm ua haujlwm. Rau cov neeg siv khoom siv thiab kev lag luam feem ntau cov xim stripping, cov lus teb tsis yog.

Yog tias koj qhov kev ua haujlwm tsis poob rau hauv ib qho kev zam tshwj xeeb thiab tsis tuaj yeem ua tau raws li kev tswj hwm nruj, DCM yuav tsum tsis txhob siv. Feem ntau, txoj kev nyab xeeb dua yog qhov kev xaiv zoo dua.

Cov European Union txwv tsis pub muag cov tshuaj methylene chloride-raws li cov xim pleev xim rau cov pej xeem thiab cov neeg siv khoom tshaj plaws hauv xyoo 2012.

California Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Kab Mob Toxic (DTSC) kuj tau txheeb xyuas cov tshuaj methylene chloride- uas muaj cov tshuaj pleev xim pleev xim uas yog cov khoom tseem ceeb rau kev soj ntsuam lwm yam kev nyab xeeb.

Txawm hais tias feem ntau cov ntawv thov tau raug txiav tawm, DCM tseem siv tau raws li kev tswj hwm nruj hauv kev saib xyuas aerospace, kev lag luam hlau tiav, thiab cov haujlwm tshwj xeeb kho dua tshiab.

1. Aerospace thiab Aircraft Maintenance

Aircraft coatings yog engineered rau huab cua durability. Hauv qee qhov kev siv, DCM tseem yog ib qho ntawm ob peb txoj kev stripping muaj peev xwm tshem tawm cov txheej txheem aerospace uas tsis muaj kev puas tsuaj rau cov substrates.

Cov kev siv ib txwm muaj xws li:

• Aircraft txheej tshem tawm
• Sealant stripping
• Cov khoom siv kho dua tshiab
• Kev kho repainting

2. Muaj hlau tiav

Qee qhov chaw ua haujlwm kaw- cov txheej txheem immersion stripping cov txheej txheem uas cov neeg ua haujlwm raug cuam tshuam tuaj yeem tswj xyuas nruj los ntawm kev ntsuas engineering.

Methylene chloride (DCM) tseem yog ib qho ntawm cov xim zoo tshaj plaws - stripping solvents puas tau tsim tawm vim nws nkag mus sai thiab dav txheej txheej. Txawm li cas los xij, kev pheej hmoo rau kev noj qab haus huv tseem ceeb-xws li mob toxicity, tsim cov pa roj carbon monoxide, thiab ntev - kev txhawj xeeb txog kev raug mob rau lub sijhawm- tau ua rau muaj kev cai nruj dua thoob ntiaj teb.

Niaj hnub no, cov neeg siv khoom siv yog txwv tsis pub siv hauv Tebchaws Meskas, thiab cov ntawv thov kev lag luam feem ntau tau txwv lossis txiav tawm. Txawm hais tias muaj kev zam tsis pub dhau mus rau aerospace, kev tiv thaiv, thiab qee cov txheej txheem kev lag luam, lwm txoj kev stripping thev naus laus zis tau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov tshem tawm cov xim niaj hnub no.
