Methacrylic acid monomer-nadiif sare leh 99%

Tilmaamaha: 200kg / durbaan

Methacrylic acid, oo inta badan loo soo gaabiyo MAA oo si habaysan loogu magac daray 2-methylpropenoic acid, waa mid aan midab lahayn ama midab huruud ah, daxalaysan, adag oo crystalline ama dareere leh sifada akrid, ur ur daran. Badeecadeena tayada sare leh waxay gaartaa 99% nadiif ah, oo soo saarta waxqabadka gaarka ah ee wax soo saarka methyl methacrylate, soo saarista resin acrylic, qaabaynta dahaarka, iyo codsiyada polymer ee gaarka ah.

Sida karboksylic acid ka ugu fudud ee leh beddelka α-methyl, methacrylic acid wuxuu leeyahay sifooyin kiimiko oo gaar ah oo ka sooca acrylic acid. Kooxda α-methyl waxay siisaa difaac adag oo isku-xidhka labanlaaban ah, taasoo keentay xasilloonida kulaylka oo la xoojiyey iyo hoos u dhaca u janjeersiga autopolymerization marka la barbar dhigo aashitada acrylic, iyadoo la ilaalinayo fal-celin heersare ah oo ku saabsan hababka polymerization-ka ee la kantaroolo. Shaqada karboksilic acid waxay awood u siinaysaa falcelinno kala duwan oo ay ka mid yihiin esterification, samaynta milixda, iyo isku xidhka hydrogen ee horumarinta adhesion polymer iyo awoodda isku xidhka.

Codsiga ugu badan ee methacrylic acid waa kaydka aasaasiga ah ee soo saarida methyl methacrylate (MMA), monomer for polymethyl methacrylate (PMMA) iyo resins acrylic. Esterification MAA ee leh methanol waxay ka dhigan tahay mid ka mid ah hababka cabbirka ugu weyn ee warshadaha akril, taageeraya wax soo saarka caagagga indhaha, dahaarka, iyo xabagta. Darajada nadiifka sare waxay hubisaa wasakhda ugu yar ee sumeeyn karta kicinta dhaleeceynta ama wax u dhimi karta tayada alaabta MMA.

Daahan biyaha ku salaysan iyo qaabaynta xabagta, methacrylic acid waxa ay u adeegtaa sidii komonomer shaqaynaysa kaas oo wanaajinaya ku dheggan substrates polar, kor u qaadaya kala firdhisanaanta midabka, oo siisa goobo falcelinta isku xidha. Kooxaha karboksilic acid waxay awood u siinayaan habdhaqanka jawaab celinta pH ee polymers-ka xalinta iyo hagaajinta xasilloonida dhalaalidda ee nidaamyada cinjirka. Codsiyada dheeriga ah waxaa ka mid ah u adeegsiga sida kala firdhiso midabada iyo nanoparticles, qayb ku jirta resins-exchange, iyo dhexdhexaad kiimiko ah oo soo saara esters methacrylate iyo monomers takhasus leh.

99% methacrylic acid saafi ah waxay la kulantaa qeexitaanno adag oo loogu talagalay maadada dimer hoose, heerarka xakamaynta xakameynaya, iyo wasakhowga ugu yar ee aldehyde iyo qoyaanka, hubinta waxqabadka esterification la isku halayn karo, dabeecad polymerization joogto ah, iyo alaabooyinka akril tayo sare leh ee soosaarayaasha MMA, soosaarayaasha dahaarka, iyo soosaarayaasha kiimikada gaarka ah ee u baahan baahida sare ee codsiyada karboksilic acid.

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.
