Polyurethane Foaming Agent - Methylene Chloride

Polyurethane Foaming Agent - Methylene Chloride, tseem hu ua dichloromethane (CH2Cl2), yog xim tsis muaj xim, pob tshab, tsis muaj kuab lom nrog cov ntxhiab tsw zoo li ether thiab qab zib. Nws qhov hnyav molecular yog 84.93, qhov ceev yog 1.326 g / cm³, melting point yog -96.8 degree, thiab boiling point yog 40.3 degree. Dichloromethane yog insoluble hauv dej, tab sis soluble nyob rau hauv feem ntau cov organic solvents xws li ethanol thiab ether. Txoj kev sib xyaw ua ke ntawm dichloromethane (CH2Cl2) yog los ntawm cov tshuaj tiv thaiv ntawm methane thiab chlorine.

Dichloromethane yog siv tau zoo hauv kev ua npuas ncauj tshuab, tshuaj thiab tshuaj pleev ib ce, xim thiab kua roj vanish tshem tawm, plastics ua, aerosols, hlau degreasing thiab tu. Nws yog siv los ua cov txheej txheem hnyav hauv nws tus kheej txoj cai thiab ua ntau yam hnyav hnyav rau kev tsim ua haujlwm thaum sib xyaw nrog lwm cov tshuaj. Methylene Chloride kev sib xyaw ua ke ntawm cov tshuaj lom neeg thiab lub cev muaj zog, suav nrog lub zog hnyav hnyav, ruaj khov, tsis muaj nplaim taws thiab tsis tshua muaj kub kub, tau ua rau nws siv ntau yam ntawm daim ntawv thov thiab kev lag luam.

Cov hauv qab no yog cov kev siv tseem ceeb ntawm dichloromethane:

1. Methylene Chloride siv rau cov kuab tshuaj: Dichloromethane yog cov kuab tshuaj organic zoo heev uas tuaj yeem yaj ntau cov organic tshuaj, suav nrog cov rog, roj, resins, roj hmab, waxes thiab qee cov polymers. Nws yog feem ntau siv nyob rau hauv chemical laboratories rau extraction, sib cais thiab ntxuav cov tshuaj tiv thaiv sib tov.

2. Methylene Chloride siv rau extractant: Txij li thaum dichloromethane muaj zoo solubility rau ntau lub tebchaw, nws yog feem ntau siv raws li ib tug extractant nyob rau hauv organic synthesis. Los ntawm nws cov polarity qis dua piv rau lwm cov kuab tshuaj, kev xaiv extraction ntawm cov tebchaw tshwj xeeb tuaj yeem ua tiav.

3. Methylene Chloride siv los ntxuav tus neeg sawv cev: Dichloromethane muaj peev xwm ntxuav tau zoo thiab feem ntau yog siv los ntxuav cov hlau, cov khoom siv hluav taws xob, qhov muag qhov muag thiab cov cuab yeej precision. Nws tuaj yeem tshem tawm cov pa phem xws li roj, siv quav ciab, kua nplaum, thiab lwm yam, tawm hauv qhov chaw huv.

4. Methylene Chloride siv rau kev lag luam kws tshuaj: Dichloromethane yog siv nyob rau hauv kev lag luam kws tshuaj rau kev npaj thiab rho tawm cov tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm extracting active cov khoom xyaw los ntawm cov nroj tsuag. Nws kuj yog feem ntau siv los ua ib qho hnyav hauv cov tshuaj formulations.

5. Methylene Chloride siv rau cov tshuaj tsuag: Vim nws qhov kub tsis tshua muaj kub thiab tsis muaj zog, dichloromethane feem ntau siv los ua cov tshuaj tsuag xws li cua fresheners, deodorants thiab lubricants.

6. Methylene Chloride siv rau kev tsim ua npuas ncauj: Dichloromethane tuaj yeem ua tus neeg sawv cev foaming hauv kev tsim cov khoom yas xws li foamed polyurethane thiab polystyrene.

Nws yuav tsum tau muab sau tseg tias dichloromethane yog ib qho tshuaj lom neeg thiab yuav tsum tau siv raws li cov txheej txheem kev nyab xeeb uas cuam tshuam thiab nyob rau hauv ib puag ncig zoo-ventilated. Nyob rau tib lub sijhawm, hauv cov ntawv thov tshwj xeeb, cov cai tshwj xeeb thiab cov cai yuav tsum tau ua raws li kom ntseeg tau tias muaj kev nyab xeeb thiab siv tau.

‌Ntim:

270kg lossis 250kg net hnyav steel nruas.

Dichloromethane (CH2Cl2) muaj qee yam kev phom sij uas cuam tshuam nrog kev mob toxicity, flammability, corrosiveness thiab ib puag ncig. Thaum thauj thiab khaws cia Methylene Chloride (MC), yuav tsum tau ceev faj kom tsim nyog. Nov yog qee cov lus qhia:

Kev thauj mus los:

- Siv cov thawv ntim khoom tsim nyog: Xaiv cov ntim ntim ntim thiab tiv thaiv corrosion los khaws cov dichloromethane, xws li lub tog raj kheej steel lossis HDPE yas nruas cim nrog UN tus lej 1593.

- Kev sau npe thiab ntim khoom: xyuas kom lub thawv ntim tau zoo, suav nrog cov npe tshuaj, cov cim phom sij thiab cov lus ceeb toom. Lub ntim yuav tsum ruaj khov thiab ua raws li cov cai hauv tebchaws thiab thoob ntiaj teb kev thauj mus los.

- Tsis txhob raug: Thaum lub sij hawm kev thauj mus los, zam lub ntim los ntawm kev vibration loj, ntog lossis tsis zoo nrog lwm yam tshuaj.

Cia:

- Qhov cua: qhov cua zoo yuav tsum tau khaws cia rau hauv qhov chaw uas dichloromethane khaws cia kom tsis txhob muaj vapor tsub zuj zuj. Xav txog kev siv tshuaj fume hood los yog lub txee ruaj ntseg kom muaj kev nyab xeeb ntxiv.

- Kev tswj qhov kub thiab txias: Dichloromethane yuav tsum muab cia rau hauv chav tsev kub thiab tsis txhob raug kub hnyiab los txo qhov kub thiab txias.

- Tsis txhob muaj qhov hluav taws kub: Qhov chaw cia yuav tsum nyob deb ntawm cov nplaim taws, qhov chaw kub, thiab lwm qhov chaw cua sov uas yuav ua rau hluav taws kub. Tiv thaiv kom tsis txhob muaj hluav taws xob zoo li qub thiab zam kev sib cuag nrog cov khoom xws li oxidants, muaj zog acids lossis cov hauv paus muaj zog.

Kev ntsuas kev nyab xeeb:

- Cov cuab yeej tiv thaiv tus kheej: Thaum tuav cov tshuaj dichloromethane, cov khoom siv tiv thaiv tus kheej tsim nyog yuav tsum hnav, nrog rau cov tsom iav tshuaj, cov hnab looj tes tiv thaiv, thiab cov khaub ncaws tiv thaiv tsim nyog.

- Tsis txhob nqus pa: Tsis txhob raug cov dichloromethane vapors ntev ntev thiab xyuas kom meej tias qhov chaw ua haujlwm yog qhov cua zoo.

- Sealing: xyuas kom meej tias lub thawv ntim tau zoo thiab tshawb xyuas cov xau tsis tu ncua.

- Kev pov tseg pov tseg: Cov methylene chloride pov tseg thiab cov khoom pov tseg uas muaj feem xyuam yuav tsum tau muab pov tseg kom zoo thiab muab pov tseg raws li cov cai hauv zos. Tsis txhob muab pov tseg ntawm qhov xav tau.

Thov nco ntsoov tias cov lus qhia saum toj no tsuas yog siv rau kev siv xwb. Kev thauj mus los tshwj xeeb thiab kev cia khoom yuav txawv nyob ntawm thaj tsam thiab cov kev cai tswj hwm. Cov neeg muas zaub uas tab tom yuav methylene chloride zoo siab txais tos los tham nrog peb.
