Cov lus nug nquag
Cov lus nug txog kev lag luam thiab kev lag luam txog Dimethylethanolamine los ntawm peb cov neeg siv khoom B2B thoob ntiaj teb.
Dimethylethanolamine (DMEA) yog dab tsi thiab nws siv rau dab tsi?
Dimethylethanolamine (DMEA, CAS 108-01-0) yog tertiary alkanolamine nrog formula C₄H₁₁NO, tseem hu ua N, N-Dimethylaminoethanol. Nws cov kev lag luam tseem ceeb yog: (1) neutralizing amine thiab pH stabilizer rau cov txheej txheem dej (acrylic, alkyd, PU, epoxy); (2) tertiary amine catalyst rau polyurethane ua npuas ncauj, coatings, thiab elastomers; (3) kev ua haujlwm nruab nrab rau ion pauv resin ntau lawm; (4) cov khoom siv hauv cov tshuaj sib xyaw amine rau cov roj qab zib thiab CO₂ ntes; (5) tshuaj thiab tshuaj lom neeg zoo nruab nrab; thiab (6) pH txias nyob rau hauv cov dej kho formulations.
Vim li cas DMEA nyiam dua KOH lossis AMP raws li qhov nruab nrab amine hauv cov txheej txheem dej?
Tsis zoo li lub hauv paus tsis muaj zog xws li KOH, DMEA evaporates tag nrho thaum lub sij hawm zaj duab xis ziab thiab kho, tawm hauv qab tsis muaj qhov seem hauv txheej txheej kawg. Qhov no ua rau muaj kev tiv thaiv dej zoo dua, kev txhim kho zaj duab xis nyuaj, thiab ua kom ntev dua - lub sij hawm ntev. Piv rau AMP (2-amino-2-methyl-1-propanol), DMEA muaj qhov hnyav dua molecular thiab ntau dua volatility, ua rau nws sai dua evaporate thiab txo cov ntxhiab tsw amine hauv cov yeeb yaj kiab qhuav. Txawm li cas los xij, DMEA qhov kev hloov pauv siab dua kuj txhais tau tias nws muaj qhov qis qis (31 degree) thiab xav tau kev ntsuas hluav taws xob tsim nyog thaum khaws cia thiab siv.
DMEA siv los ua polyurethane catalyst li cas?
Hauv polyurethane ua npuas ncauj ntau lawm, DMEA ua raws li tertiary amine catalyst uas ua rau ob qho tib si urethane - tsim (gel) cov tshuaj tiv thaiv ntawm isocyanate thiab polyol thiab tshuab cov tshuaj tiv thaiv ntawm isocyanate thiab dej. Nws muab kev ua haujlwm nruab nrab, sib npaug catalytic tsim nyog rau ntau hom kev hloov pauv tau yooj yim thiab ib nrab - cov qauv ua npuas nruj. DMEA feem ntau yog siv los ua ke nrog lwm cov tertiary amine catalysts xws li DABCO (triethylenediamine) los yog bis (dimethylaminoethyl) ether kom nplua -tune ua npuas ncauj nce ceev, cream lub sij hawm, thiab demold yam ntxwv rau tej daim ntawv thov.
Dab tsi yog qhov txawv ntawm DMEA thiab TEA (triethanolamine) li neutralizing amines?
Ob leeg DMEA thiab TEA yog tertiary amines siv los nruab nrab cov txheej txheem dej, tab sis lawv sib txawv hauv qhov tsis muaj zog thiab daim ntawv thov profile. DMEA (bp 134 degree, MW 89) yog volatile heev thiab evaporates yooj yim thaum tsim zaj duab xis, tawm hauv amine - dawb txheej. TEA (bp 335℃, MW 149) yog qhov tseem ceeb tsis yog -volatile thiab tseem nyob hauv cov yeeb yaj kiab qhuav. TEA yog qhov zoo dua thaum xav tau tus neeg sawv cev tsis tu ncua lossis thaum sib koom ua ke ntawm qhov kub thiab txias yog qhov tseem ceeb; DMEA yog qhov zoo dua thaum qhov dej siab tshaj plaws thiab kev txhim kho hardness ntawm zaj duab xis zaum kawg.
Dab tsi purity qib SinoLook Chem muab rau DMEA?
SinoLook Chem muab DMEA ntawm ntau dua lossis sib npaug rau 99.0% purity (GC assay), nrog rau cov txiaj ntsig zoo ntawm 99.5–99.8%. Cov ntsiab lus dej tsawg dua lossis sib npaug li 0.2% (feem ntau 0.08–0.12%) thiab xim tsawg dua lossis sib npaug li 20 APHA (feem ntau Tsawg dua lossis sib npaug li 10). Ib qib siab dua -purity qib (Ntau dua lossis sib npaug li 99.5%) muaj nyob rau ntawm kev thov rau kev siv tshuaj, kev siv cGMP, thiab cov tshuaj siv hluav taws xob. Daim ntawv pov thawj tag nrho ntawm Kev Ntsuam Xyuas (CoA), Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS), thiab Daim Ntawv Qhia Txog Kev Tshawb Fawb (TDS) tau muab rau txhua qhov khoom xa tuaj.
Dab tsi yog qhov kev cia thiab tuav cov cai rau DMEA?
DMEA muaj lub teeb nyem ntawm 31℃thiab yuav tsum tau muab khaws cia ua cov kua hluav taws xob hauv qhov txias (5-30 degree), zoo- qhov cua, tawg- thaj chaw pov thawj deb ntawm qhov chaw tshav kub, taws, thiab qhib nplaim taws. Khaws kom deb ntawm cov kua qaub uas muaj zog, muaj zog oxidizers, thiab cov kua qaub chlorides. Siv UN- pom zoo steel nruas lossis IBC ntim; zam tooj liab thiab tooj liab alloys. Hnav cov tshuaj chemical-cov hnab looj tes tiv thaiv (nitrile lossis butyl roj hmab), tsom iav kev nyab xeeb, daim npog ntsej muag, thiab tshuaj apron thaum tuav. Kev pom zoo tso pa tawm hauv zos; siv cov khoom siv antistatic los tiv thaiv electrostatic ignition.
Dimethylethanolamine HS code yog dab tsi?
Dimethylethanolamine (CAS 108-01-0) yog cais raws li HS code2922.19(amino alcohols - lwm yam, uas tsis yog cov uas muaj cov pa oxygen nkaus xwb - muaj pawg li heteroatoms, lawv ethers thiab esters; ntsev ntawm no). Nco ntsoov lees paub cov cai siv tariff nrog koj lub chaw lis kev lis kev cai hauv zos, vim tias kev faib tawm yuav txawv ntawm txoj cai.
