Tshooj Ob Kev Siv Dimethyl carbonate (DMC)

1. Xim, txheej thiab nplaum kev lag luam

Vim nws zoo heev solubility, nqaim melting thiab boiling point ranges, loj nto nro, tsis tshua muaj viscosity, thiab me me dielectric tas li, dimethyl carbonate tuaj yeem hloov tshuaj lom toluene thiab xylene khoom thiab yog dav siv nyob rau hauv high-end xim, coatings, adhesives, thiab lwm yam. Kua nplaum thiab lwm yam kev lag luam.

2. Polycarbonate kev lag luam

Dimethyl carbonate yog dav siv nyob rau hauv ntau yam organic tshuaj thiab maj mam hloov phosgene nyob rau hauv zus tau tej cov polycarbonate thiab isocyanate, uas muaj ib tug loj kev lag luam sib txawv. Polycarbonate yog cov khoom siv niaj hnub uas muaj kev cuam tshuam zoo heev. Nws yog tib yam khoom uas muaj pob tshab zoo ntawm tsib qhov loj engineering yas. Nws tseem yog qhov loj hlob sai tshaj plaws engineering yas hauv xyoo tas los no. Nws yog tam sim no siv dav hauv tsheb, hluav taws xob thiab hluav taws xob, kev tsim kho, khoom siv hauv chaw ua haujlwm, ntim khoom, khoom siv ua kis las, kev kho mob thiab lwm yam haujlwm. Nrog rau kev sib txuas ntxiv ntawm kev tshawb nrhiav kev hloov kho, nws tau nthuav dav mus rau hauv high-tech teb xws li aerospace, computers, optical discs thiab lwm yam.

3. Lithium-ion roj teeb electrolyte

Nrog rau kev siv tas mus li ntawm lub teb chaws tshiab lub zog kev lag luam txoj kev npaj, hluav taws xob mopeds thiab hluav taws xob tsheb lag luam, nyob rau hauv kev taw qhia ntawm lub teb chaws tshiab zog lub tswv yim, Dimethyl carbonate tau dhau los ua ib qho ntawm cov lag luam uas muaj kev lag luam tshaj plaws hauv kuv lub teb chaws yav tom ntej. Raws li txoj cai, cov zis thiab kev xav tau ntawm kev lag luam roj teeb lithium kuj tau nce ntxiv. Kev loj hlob sai dua. Raws li ib qho ntawm cov khoom siv tseem ceeb rau roj teeb electrolyte, carbonate cov khoom yuav muaj kev loj hlob sai hauv kev thov hauv cov roj teeb lithium.

4. Roj additives

Vim nws cov ntsiab lus oxygen siab (oxygen ntsiab lus 53%, peb npaug ntawm MTBE) thiab qhov tsim nyog vapor siab, dej tsis kam thiab sib xyaw coefficient, Dimethyl carbonate tuaj yeem siv los ua cov roj av zoo tshaj plaws / diesel ntxiv los txhawb kev sib txuas thiab nce octane. tus nqi, txo cov pa roj carbon emissions, thiab tib lub sij hawm txhim kho kev tiv thaiv kev ua haujlwm ntawm cov roj av / diesel.

5. Kev lag luam kws tshuaj

Kev lag luam kws tshuaj tam sim no yog ib qho tseem ceeb ntawm cov khoom siv rau dimethyl carbonate hauv kuv lub teb chaws. Hauv cov tshuaj, dimethyl carbonate feem ntau yog siv los ua tus neeg sawv cev methylating los hloov cov tshuaj lom heev dimethyl sulfate, thiab yog siv los tsim cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob. cov tshuaj, cov vitamins, thiab cov tshuaj hauv nruab nrab paj hlwb.

6. Tshuaj tua kab

kuv lub teb chaws yog ib tug loj tsim tshuaj tua kab. Raws li kev hloov pauv ntawm cov qauv ntawm kuv lub teb chaws txoj kev lag luam tshuaj tua kab nrawm dua, lub teb chaws txoj cai rau kev nyab xeeb tshuaj tua kab yuav nruj zuj zus. Cov tshuaj tua kab uas muaj tshuaj lom heev yuav maj mam hloov los ntawm cov khoom siv tshuaj tua kab uas tsis muaj tshuaj lom thiab tsis muaj tshuaj lom. Yog li ntawd, raws li ib tug ntsuab Daim ntawv thov ntawm ib puag ncig tus phooj ywg intermediate dimethyl carbonate cov khoom nyob rau hauv lub teb ntawm tshuaj tua kab ntau lawm yuav muaj broad txoj kev cia siab.

7. ADC cob

Allyl diglycol carbonate (ADC) muaj cov khoom siv kho qhov muag zoo, hnav tsis kam, kab mob ua haujlwm, thiab lub teeb yuag. Nws yog ib qho thermosetting resin. Nws tuaj yeem hloov iav thiab siv los ua cov tsom iav tsom iav thiab cov khoom siv optoelectronic. Nws yog Ameslikas tsim los ntawm propylene cawv, diethyl glycol thiab phosgene. Niaj hnub no, kev lag luam feem ntau siv DMC los hloov phosgene. Vim tias DMC yog cov tshuaj lom neeg tsawg thiab tsis muaj corrosive, nws txo cov kev xav tau hauv kev tsim khoom, kev tswj xyuas kev ua haujlwm thiab kev kho cov khib nyiab. Qhov tseem ceeb tshaj, cov khoom zoo tuaj yeem tsim tau yooj yim dua. Yog li ntawd, cov teb tshiab xws li kev siv cov khoom siv optoelectronic precision raug qhib.
