Methyl Methacrylate Monomer oo nadiif ah oo nadiif ah 99.9%

Gaar ahaan: 190kg / durbaan

Methyl methacrylate, oo inta badan loo soo gaabiyo MMA oo si nidaamsan loogu magac daray methyl 2-methylpropenoate, waa dareere aan midab lahayn, degenaansho lahayn, olol leh oo leh ur sifada ah, ur macaan. Badeecadeena nadiifinta aadka u saraysa ee 99.9% waxay bixisaa tayo gaar ah oo loogu talagalay soosaarka polymethyl methacrylate (PMMA), wax soo saarka xaashida akril, qaabaynta dahaarka, iyo codsiyada kala duwan ee u baahan hufnaanta indhaha iyo iska caabinta cimilada.

Sida methyl ester-ka methacrylic acid, MMA waxa ay leedahay isku xidh labajibbaaran oo kaarboon-carbon ah oo firfircoon oo leh beddelka α-methyl kaas oo bixiya sifooyin polymerization gaar ah. Habkan qaabdhismeedku waxa uu abuuraa monomer si adag u xanniban marka la barbar dhigo methyl acrylate, taas oo keentay in polymers leh heerkul kala-guurka dhalo sare (Tg ~ 105 ° C ee PMMA), qallafsanaan wanaajiyay, iyo sifooyin muuqaal ah oo aad u fiican. Kooxda α-methyl waxay sidoo kale yareysaa falcelinta wareejinta silsiladda inta lagu jiro polymerization, taasoo awood u siineysa soo saarista polymers culeyska kelliyada sare leh oo leh waxqabadka farsamada sare.

Warshadaha polymethyl methacrylate (PMMA) waxay matalaan codsiga MMA ee ugu weyn uguna muhiimsan, halkaas oo ay u adeegto sida monomer-ka gaarka ah ee soo saarida galaaska akril, oo inta badan loo yaqaan magacyada ganacsiga sida Perspex, Plexiglas, iyo Lucite. Cadaynta indhaha ee gaarka ah ee PMMA (92% gudbinta iftiinka), xasiloonida UV, iyo cimilada ayaa ka dhigaysa lama huraan u ah dhaldhalaalka dhismaha, nalka baabuurta, muraayadaha indhaha, calaamadaha, iyo aaladaha caafimaadka. 99.90% darajada daahirintu waxay hubisaa wasakhda ugu yar ee keeni karta midab, ceeryaamo, ama hoos u dhac ku yimaada alaabta akril ee dhammaatay.

Dahaarka dusha sare, methyl methacrylate wuxuu ka qayb qaataa resins heerkul-kuleyl leh oo leh adkeysi dibadeed oo heer sare ah, xajin dhalaalaysa, iyo caabbinta kiimikaad ee dusha sare ee baabuurta iyo dhamaystirka warshadaha. Warshadaha ilkaha iyo caafimaadka waxay u isticmaalaan MMA si ay u soo saaraan sibidhka lafaha, prosthetics-ka ilkaha, iyo muraayadaha indhaha. Codsiyada dheeriga ah waxaa ka mid ah isticmaalka dhar-dhamaadka, dahaarka maqaarka, iyo wax ka beddelayaasha saameynta polyvinyl chloride (PVC).

99.9% methacrylate saafi ah waxay la kulmeysaa qeexitaannada heerka polymerization adag ee acidity aadka u hooseeya, heerarka xakamaynta xakameynaya (sida caadiga ah hydroquinone monomethyl ether ama Topanol), iyo biyaha ugu yar iyo aldehyde, hubinta polymerization bulk la isku halayn karo, wax soo saarka xaashida, iyo farsamaynta joogtada ah ee soosaarayaasha xaashida acrylic, soosaarayaasha qalabka wax soo saara ee ugu sareeya codsiyo muhiim u ah howlgalka.

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.
