Methyl Methacrylate Material Ceyriin ah oo Tayo Sare leh oo loogu talagalay Resins

Faahfaahinta alaabta

Methyl methacrylate (MMA), oo sidoo kale loo yaqaano isobutylene acid methyl ester, waa monomer-synthetic organic oo muhiim ah. Qaabka kiimikaadkeedu waa C₅H₈O₂, oo leh miisaan kelli ah 100.116 iyo lambarka CAS ee 80-62-6. Heerkulka qolka, waa dareere hufan oo aan midab lahayn oo leh ur daran. Wax yar bay ku milmi kartaa biyaha waxayna si sahal ah ugu milmi kartaa inta badan dareerayaasha organic sida ethanol iyo ether.

Codsiga alaabta

Methyl methacrylate (MMA) waa monomer kiimiko organic muhiim ah, inta badan loo isticmaalo synthesizing polymethyl methacrylate (PMMA, oo sida caadiga ah loo yaqaan plexiglass), kaas oo si ballaaran loo codsado in qalabka indhaha, qalabka caafimaadka, dhismaha, gaadiidka, daahan, koollada, iwm.

1. Wax soo saarka PMMA: monomer xudunta u ah, waa polymerized si ay u sameeyaan PMMA, kaas oo loo isticmaalo in lagu soo saaro go'yaal hufan, bandhigay kiisaska, daboolka laambad baabuurta, panel panels, iwm. Sababo la xiriira gudbinta iftiinka sare (ilaa 92%), khafiif ah (cufnaanta 1.2 g/cm³) iyo caabbinta cimilada, waxay bedeli kartaa galaas caadiga ah.

2. Dahaarka iyo xabagta: Waxaa loo isticmaalaa in lagu soo saaro dahaarka acrylate-ku salaysan (sida rinjiga baabuurta, dahaarka dhismaha), bixinta caabbinta cimilada wanaagsan, ilaalinta iftiinka iyo sifooyinka qurxinta; waxa kale oo loo isticmaalaa in lagu diyaariyo xabagta xasaasiga ah ee cadaadiska, xabagta qaab dhismeedka, iwm.

3. Daawooyinka iyo biomedical: PMMA waxaa loo isticmaalaa muraayadaha macmalka ah (oo leh in ka badan 300 milyan oo xaaladood oo la geliyay tan iyo 1949), saldhigyada ilkaha, qaybo hufan ee dhallaanka, iwm.

4. Codsiyada dhismaha iyo warshadaha: Waxaa loo isticmaalaa saqafyada iftiinka iftiimaya, muraayadaha lagu daboolo aqalka dhirta lagu koriyo (oo leh iftiin iftiin leh oo ka sarreeya 15% ka sarreeya muraayadda), xannibaadaha qaylada waddooyinka (yaraynta qaylada 35 dB), iwm, iyada oo ka faa'iideysanaysa gudbinta iftiinka iyo iska caabbinta saameynta.

5. Hawada sare iyo gaadiidka: Waxaa loo isticmaalaa daaqadaha dayuuradaha, daboolka laambada dabada baabuurka, muraayadaha muraayadaha xabadu karin, iwm.

6. Beeraha kale: Waxaa loo isticmaalaa in lagu soo saaro monomer labaad ee fiilooyinka acrylic, wakiilada daaweynta maqaarka, waraaqaha gloss waraaqaha, waxyaabaha lagu daro saliidaha, alaabta wax lagu dhejiyo, iwm, sababtoo ah milanka wanaagsan iyo iswaafajinta.

Xaaladda kaydinta

Methyl methacrylate (MMA) waa in lagu kaydiyaa bakhaar qabow oo hawo fiican leh, kana fog ilaha dabka iyo meelaha kulaylka, iyada oo heerkulku aanu dhaafin 30-37℃. Baakadaha waa in la xiraa si looga hortago in hawada la taabto, waana in si gooni ah loo keydiyaa oksidat, acids, bases, halogens, iwm.

1. Xakamaynta deegaanka: Bakhaarka kaydinta waa in lagu hayaa qabow, engegan, oo hawo fiican leh, iyada oo heerkulku aanu dhaafin 30-37 ℃ (kala duwanaansho ayaa laga yaabaa inay kala duwanaato iyadoo ku xiran ilo kala duwan), iyada oo laga fogaado iftiinka qorraxda tooska ah ama jawiga heerkulka sare si looga hortago dardargelinta falcelinta polymerization.

2. Xiritaanka weelka: Baakadu waa in si adag loo xiraa si looga hortago in hawada la taabto. Caadi ahaan, xasiliyeyaasha (sida hydrogen peroxide monomethyl ether) ayaa lagu daraa alaabta si loo joojiyo polymerization, iyo weelka waa inuu ahaadaa mid nadiif ah si looga hortago daadinta.

   Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
