Methyl acetate yog ib qho kev sib raug zoo rau ib puag ncig, feem ntau siv los dilute xim, pleev xim los yog ua cov tshuaj ntxuav, nrog cov ntxhiab tsw tsw qab. Nws kuj yog siv nyob rau hauv kev lag luam niaj hnub rau kev tsim cov kua nplaum thiab cov tshuaj tsw qab.Nws yog mos thiab nyab xeeb dua li acetone thiab lwm cov kuab tshuaj, thiab ntau tus phooj ywg rau tib neeg lub cev thiab ib puag ncig.
Cov yam ntxwv ntawm cov khoom tseem ceeb raws li hauv qab no
Ceev- ziab
Qhov kub ntawm qhov kub yog 56.9 degree, thiab tus nqi evaporation yog li 5.0 (raws li butyl acetate =1), uas yog ceev heev. Nws ua kom muaj txiaj ntsig zoo hauv cov coatings, inks, thiab cov tshuaj ntxuav. Tshwj xeeb tshaj yog nyob rau hauv siab - cov kab ntau lawm ceev, nto ziab yog ua tiav yuav luag tam sim ntawd thaum lub sij hawm txau, txo cov txheej txheem lub sij hawm.
Muaj zog solubility
Solubility ntawm nitrocellulose thiab cellulose acetate yog 30-40% siab dua ethyl acetate. Nws muaj qhov zoo heev solubility rau cov roj polar thiab rosin fluxes, tab sis yuav luag tsis zoo rau cov tsis-polar resins xws li roj av resins.
Ib puag ncig tus phooj ywg
Nws muaj biodegradability zoo thiab tuaj yeem decompose sai hauv ib puag ncig. Nws tsuas yog tsim cov CO2 thiab H2O tom qab photolysis, tsis tsim cov kuab paug tsis tu ncua, thiab tsis tas yuav tsum tau tshaj tawm tias cov pa phem huab cua hauv cov khoom xa tawm.
Tus nqi MIR yog kwv yees li 0.12, uas tsuas yog 1/10 ntawm toluene thiab belongs rau qis reactivity VOCs. Nws txaus siab rau VOC kev zam hauv qee lub xeev hauv Tebchaws Meskas thiab cov ntawv thov tshwj xeeb hauv European Union, thiab tsis suav nrog REACH cov npe ntawm cov khoom muaj kev txhawj xeeb siab. Tab sis nws tseem yuav tsum tau ua raws li cov cai tswj kev nyab xeeb thaum siv.
Daim ntawv thov
Adhesive teb
Qhov sib ntxiv ntawm methyl acetate rau cov nplaum, nws cov volatility siab pab kom tshem tawm cov kuab tshuaj sai sai, txo lub sijhawm kho ntawm cov nplaum, txhim kho kev ua haujlwm.
Kev ntxuav ntawm Circuit Board
After reflow soldering, remove rosin based flux with a removal rate of>95% rau polar pollutants, thiab sai sai evaporate yam tsis muaj seem seem
Ntsia polish formula
Raws li cov kuab tshuaj tseem ceeb rau nitrocellulose, nws muab cov yam ntxwv kom qhuav sai (30 stopwatch kom qhuav) thaum tswj siab glossiness thiab tsis tshua muaj ntxhiab tsw tom qab volatilization
Txheej
Hauv kev sib dhos kab txheej txheej ntawm ABS thiab PS cov khoom ua si yas, lub sijhawm ziab ntawm cov xim zaj duab xis tuaj yeem tswj tau li ntawm 15 vib nas this, thiab nws tuaj yeem nkag mus rau cov txheej txheem ntim khoom ncaj qha. Tib cov kab ntau lawm tuaj yeem ua kom muaj peev xwm ntau lawm los ntawm 30-50%. Hauv cov txheej txheem tsheb, ntsia thawv polish, xim tu thiab lwm yam lag luam, methyl acetate tuaj yeem txo lub sijhawm ziab, tshwj xeeb tshaj yog rau cov kev xav tau ntawm kev ziab sai.

FAQ
Q: Vim li cas thiaj pom zoo kom ntxuav cov cuab yeej precision?
A: Nws muaj zog nkag mus thiab volatile yam tsis muaj residue yam ntxwv tuaj yeem zam cov kua ua puas rau cov khoom siv hluav taws xob, kom tsis muaj kab tom qab ntxuav.
Q: Dab tsi yog kev siv nws hauv cov tshuaj?
A: Raws li cov kuab tshuaj me me rau cov tshuaj txheej los yog tshem tawm cov khoom xyaw nquag, nws tsis txhob kub siab rau kev ua yeeb yam thiab txo qhov kev pheej hmoo ntawm residue.
Q: Yuav ua li cas kom tsis txhob muaj kua seem tom qab ntxuav?
A: Nws evaporates sai heev thiab tsis tas yuav tsum tau so ntxiv, ua rau nws tshwj xeeb tshaj yog haum rau tu kho mob endoscopes los yog kuaj iav iav.
Q: Nws tuaj yeem ua dab tsi los tshem tawm cov nplaum nplaum?
A: Nws yog maj mam rau ntawm cov yas thiab hlau, softens cov kua nplaum tsis muaj corroding cov khoom, thiab yooj yim rov qab huv si tom qab tshem cov ntawv nplaum lossis cov ntawv lo.
Q: Yuav ua li cas kom tsis txhob tawg thaum cuam tshuam nrog cov rooj tog ntoo?
A: Kev tawg ntawm ntoo lacquer yog me me thiab tsis nqus dej ntau dhau ntawm cov ntoo. Tom qab pleev xim rau, cov lacquer zaj duab xis yog ib yam thiab qhov kev pheej hmoo ntawm ziab thiab tawg yog txo.
Q: Yuav ua li cas pov tseg cov methyl acetate tas sij hawm los yog pov tseg?
A: Ib qho me me tuaj yeem tso cua ncaj qha thiab tsis hloov pauv, thiab cov kua khib nyiab ntau tuaj yeem rov ua dua li cov kuab tshuaj zoo tib yam, tsis muaj cov txheej txheem kho cov pov tseg tshwj xeeb.
