N N-Dimethylacetamide (DMAC) 99.9%

Gaar ahaan: 190kg / durbaan

N,N-Dimethylacetamide, oo inta badan loo soo gaabiyo DMAC, waa dareere aan midab lahayn, hygroscopic oo leh ur ammonia u eg ama ur kalluun ah. Badeecadeena nadiifka ah ee aadka u sarreeya ee 99.9% waxay soo bandhigtaa waxqabadka gaarka ah ee farsamaynta polymer, isku-darka dawooyinka, soo saarista agabka horumarsan, iyo dalabka falcelinta kiimikaad ee u baahan awoodda xalinta sare.

Sida dareere aprotic ah oo leh kulayl aad u wanaagsan iyo xasilloonida kiimikada, DMAC waxay leedahay sifooyin gaar ah oo ka sooca dareerayaasha kale ee amide. Unugyadu waxay isku daraan daqiiqad dipole xoog leh (μ = 3.8 D) oo leh dielectric joogto ah (ε = 37.8), taasoo awood u siinaysa kala diris hufan oo polymers polar, cusbada aan organic, iyo tiro balaadhan oo ah xeryahooda organic. Si ka duwan dareerayaasha protic, maqnaanshaha curaarta OH ama NH waxay ka hortagtaa ku-deeqidda dammaanadda hydrogen, taasoo ka dhigaysa DMAC gaar ahaan ku habboon falcelinta ku lug leh saldhigyada xooggan, nucleophiles, iyo reagents organometallic halkaasoo wareejinta proton ay wax u dhimeyso xulashada falcelinta.

Warshadaha fiber synthetic waxay u taagan yihiin codsiga ugu muhiimsan ee DMAC, halkaas oo ay u adeegto sida dareeraha aasaasiga ah ee soo saarida polyacrylonitrile ( fibre acrylic), spandex (polyurethane elastomers), iyo fiilooyinka aramid sida Kevlar iyo Nomex. Kartida dareeruhu u leeyahay inuu ku milmo polymer-yadan waxqabadka sare leh ee heerkulka sare leh, oo ay weheliso sifooyinka rheological ee wanaagsan, waxay awood u siinaysaa geeddi-socod xalinta kuwaas oo soo saara fiilooyinka leh awood gaar ah, xasilloonida kulaylka, iyo caabbinta kiimikada. Darajada nadiifka sare waxay hubisaa wasakhda ugu yar ee saameyn karta midabka fiber-ka, xoogga, ama xasiloonida habaynta.

Soo saarista dawooyinka, DMAC waxay u shaqeysaa sidii falcelinta falcelinta isku dhafan ee isku dhafka peptide, falcelinta beddelka nucleophilic, iyo kimistariga organometallic. Barkeeda karkarinta ee sarreeya (165°C) waxay taageertaa falcelinta heerkulka sare iyadoo la ilaalinayo xasilloonida kulaylka. Xaruntu waxay u adeegtaa sidii isku-darka loogu talagalay hababka crystallization iyo sida wax-soo-saarka daroogada ee la xakameeyey.

Codsiyada dheeriga ah waxay ka kooban yihiin sida dareere loogu talagalay batariyada lithium-ion, dhexdhexaadiyaha falcelinta ee soo saarista polymers-ka iyo dahaarka, rinjiga iyo dahaadhka ka saara, iyo dareeraha nadiifinta ee semiconductor iyo elektiroonigga. Xalka ugu fiican ee polyimides wuxuu taageeraa guddiga wareegyada dabacsan iyo wax soo saarka isku dhafan ee horumarsan.

Our 99.9% saafi ah N, N-dimethylacetamide la kulantaa qeexitaanno adag ee acidity hooseeyo, content biyaha ugu yar, iyo heerarka biraha la kontaroolo, hubinta waxqabadka la isku halayn karo ee saarayaasha fiber, shirkadaha dawooyinka, soo saarayaasha batteriga, iyo qalabka horumarsan cilmi u baahan heerka ugu sareeya dareeraha polar polar aprotic codsiyada synthetic muhiim ah.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.
