Product Description
Nta
Peb Dimethylacetamide (DMAC) yog tsim nyob rau hauv nruj tswj cov qauv, kom ntseeg tau siab purity, tsis tshua muaj noo noo cov ntsiab lus, thiab ruaj khov tshuaj. Nws pom zoo thermal stability thiab muaj zog polarity, ua kom nws yaj ntau yam ntawm cov organic thiab inorganic tebchaw zoo. Nws qhov volatility tsawg kuj ua rau nws haum rau siab -kub muaj txheej txheem.
Qhov zoo
Piv nrog rau cov qauv kev lag luam-qib DMAC, peb cov khoom muaj cov khoom zoo tshaj plaws purity, txo cov impurities, thiab cov khoom zoo ib yam -rau-batch stability. Qhov no ua kom paub tseeb tias qhov kev ua tau zoo hauv cov tshuaj tiv thaiv rhiab heev, txo cov kev cuam tshuam sab nraud, thiab txhim kho cov txheej txheem tag nrho hauv kev tsim khoom lag luam.
Cov txiaj ntsig
Kev siv siab - zoo DMAC pab cov tuam txhab txhim kho cov tshuaj tiv thaiv kev ua haujlwm, txhim kho cov khoom lag luam tawm los, thiab ua tiav kev tswj hwm zoo dua hauv polymerization thiab tshuaj synthesis. Nws muaj zog solvency txo cov sij hawm ua thiab kev siv zog, pab cov neeg siv khoom txo cov nqi tsim khoom thaum tswj cov khoom zoo.
Cov pov thawj
Kev soj ntsuam kuaj pom zoo DMAC purity Ntau dua lossis sib npaug rau 99.9%, nrog cov dej tswj cov ntsiab lus thiab cov khoom seem tsawg tsawg. Peb cov khoom ua raws li ISO nruj tswj cov txheej txheem, ua kom muaj kev ntseeg siab thiab sib xws rau kev siv thoob ntiaj teb kev lag luam thoob plaws kev lag luam tshuaj, fibers, thiab coatings industries.

FAQ
Q1: Dab tsi yog qhov txawv ntawm DMAC thiab DMF (dimethylformamide)?
A: DMAC muaj qhov kub siab dua (165℃vs . 153℃rau DMF) thiab zoo dua thermal / hydrolytic stability. Nws kuj tseem nyiam nqus dej tsawg thiab feem ntau nyiam rau kev ua haujlwm kub polyimide. Txawm li cas los xij, DMF yog pheej yig dua thiab siv dav dua hauv cov tshuaj tiv thaiv dav dav. DMAC yog tus qauv rau kev siv spandex thiab polyimide.
Q2: Puas yog DMAC soluble hauv dej?
A: Yog, DMAC yog tag nrho miscible nrog dej nyob rau hauv tag nrho cov proportions. Nws kuj yog miscible nrog feem ntau cov kuab tshuaj organic (cawv, ethers, ketones, aromatics, chlorinated solvents).
Q3: Dab tsi yuav tsum tau ceev faj txog kev nyab xeeb thaum tuav DMAC?
A: DMAC yog teratogenic txaus ntshai - zam kev sib cuag ntawm daim tawv nqaij thiab nqus tau pa. Siv cov tshuab kaw thiab hnav cov hnab looj tes tiv thaiv kab mob (butyl roj hmab lossis PVA), tsom iav, thiab lub tshuab ua pa yog tias qhov cua tsis zoo. DMAC kuj yog cov kua hluav taws xob (flash point 70 degree). Peb muab cov ncauj lus kom ntxaws MSDS nrog txhua qhov khoom xa tuaj.
Q4: Lub txee lub neej ntawm DMAC yog dab tsi?
A: 24 lub hlis thaum khaws cia hauv cov thawv ntim khoom qub hauv qhov chaw txias, qhuav, qhov cua zoo, kom deb ntawm cov oxidizers thiab lub teeb. Tom qab qhib, khaws cia hauv qab nitrogen kom tsis txhob ya raws, uas tuaj yeem ua rau acetic acid tsim.
Q5: Cov kev xaiv ntim khoom twg muaj?
A: Peb muab 190 kg net steel nruas, 1000 L IBC totes (kwv yees . 940 kg net), thiab bulk ISO tank ntim (txog 20 tons). Tag nrho cov ntim khoom raws li UN cov cai tswj kev phom sij (UN 3314, Chav Kawm 3, PG III).
Q6: Dab tsi yog qhov tsawg kawg nkaus xaj kom muaj nuj nqis (MOQ) rau DMAC?
A: Ib lub nruas (190 kg) rau kev ntsuam xyuas. Kev txiav txim lag luam pib los ntawm 2 tons (kwv yees . 10 nruas lossis ib qho IBC tote). Kev txiav txim ntau tank (15-20 tons) yog muaj nrog tus nqi tseem ceeb.
Q7: Cov ntaub ntawv xa tawm dab tsi koj muab nrog DMAC xa khoom?
A: Daim ntawv pov thawj kev lag luam, cov ntawv ntim khoom, Daim Ntawv Sau Npe, COA, MSDS, DG tshaj tawm, thiab raws li kev thov: Daim Ntawv Pov Thawj Keeb Kwm (C/O), GHS cov ntawv, REACH tsab ntawv ua raws, lossis daim ntawv pov thawj phytosanitary (yog tias xav tau).
