I-Methyl Methacrylate CAS No.80-62-6

Ukucatshangelwa Kokuphepha Kokuphatha I-Methyl Methacrylate

Nakuba i-MMA iyinto ebalulekile yezimboni, ukusetshenziswa okufanele kubaluleke kakhulu. Ihlukaniswa njengoketshezi oluvutha umlilo (i-UN 1247) kanye nesikhumba esingase sibe nokucasula ukuphefumula. Imihlahlandlela esemqoka ihlanganisa:

• Isitoreji : Gcina ezindaweni ezipholile, ezinomoya omuhle kude nemithombo yokuthungela; sebenzisa iziqukathi zensimbi engagqwali noma ze-HDPE ukuvimbela ukwenziwa kwe-polymerization.

  
  

• Izisetshenziswa Zokuzivikela Zomuntu Siqu (PPE) : Gqoka amagilavu ​​e-nitrile, izibuko zokuphepha, nama-respirator ngesikhathi ubambe ukuze ugweme ukuzwela noma ukuchayeka ekuhogeleni.

  
  

• Impendulo Ephuthumayo : Uma kwenzeka uthintwa, hlambulula ngamanzi imizuzu engu-15; funa usizo lwezokwelapha ngenxa yokucasuka okungapheli. Sebenzisa izicisha-mlilo ezinomakhemikhali owomile ukuze ushise.

  
  

• Ukuthobela Umthetho : Ithobela izindinganiso zomhlaba jikelele njenge-REACH ne-TSCA; qapha amazinga womhwamuko angaphansi kuka-100 ppm TWA.

  
  

Ukubeka kuqala lezi zinqubo kuqinisekisa indawo yokusebenza ephephile ngaphandle kokufaka engozini ukusetshenziswa kwe-MMA.

Izicelo ze-Methyl Methacrylate

Ukusebenza kabusha kwe-MMA nokuzivumelanisa nezimo kushayela ukusetshenziswa kwayo emikhakheni eyahlukene. I-polymerize ibe ama-homopolymers noma ama-copolymers, ithuthukisa ukuqina komkhiqizo kanye nobuhle:

• AmaSpredishithi namaphaneli e-Acrylic (PMMA) : Asetshenziswa ekucwebezelweni kokuphepha, izimpawu, nezibonisi zezakhiwo zokubonisa ngale okumelana nokuphahlazeka.

  
  

• Ama-coatings nopende : Ihlinzeka ngokuqedwa kokumelana nesimo sezulu ezindaweni zangaphandle zezimoto nezasolwandle.

  
  

• Izinamathiselo nama-Sealants : Izinsimbi zamabhondi, amapulasitiki, nezinhlanganisela ezinamandla okugunda okuphezulu ekusetshenzisweni kwesakhiwo.

  
  

• Amadivayisi Amazinyo nawezokwelapha : Akha ama-prosthetics ahambisana ne-biocompatible kanye nezifakelo zamathambo ngenxa yokungabi namandla kwawo kanye nokucwebezelisa.

  
  

• Izinto Ezihlanganisiwe : Iqinisa imicu ku-aerospace nasezimpahleni zemidlalo ukuze zibe namandla angasindi.

  
  

• Uyinki Nokuphrinta : Ithuthukisa ukunamathela nokuvumelana nezimo ekwakhekeni okulapheka kwe-UV.

  
  

Kusukela ezimpahleni zansuku zonke zabathengi njengezikrini zefoni kuya ezenzweni ezintsha zemboni ezifana nama-wind turbine blades, i-MMA inika amandla imikhiqizo esebenza isikhathi eside.

Imibuzo Evame Ukubuzwa (FAQs) Mayelana ne-Methyl Methacrylate

Iyini i-Methyl Methacrylate (MMA)?

I-Methyl Methacrylate iyi-ester ye-methacrylic acid, i-monomer yoketshezi ecacile eyenza i-polymerize yakhe amapulasitiki aqinile, abonisa ngale njengengilazi ye-acrylic. Ikhiqizwa ngenqubo ye-acetone cyanohydrin noma i-ACH futhi isebenza njengesandulela samarensi e-PMMA.

Yiziphi ukusetshenziswa okuyinhloko kwe-MMA?

I-MMA isetshenziswa kabanzi ekukhiqizeni amashidi e-acrylic, amapende, izinto zokunamathisela, izinto zamazinyo, nezinhlanganisela. Isebenza ngezimboni zezimoto, ezokwakha, zikagesi, nezokunakekelwa kwempilo.

Ingabe i-Methyl Methacrylate iphephile emikhiqizweni yabathengi?

Uma zenziwe kahle futhi zelashwa, ama-polymers asekelwe ku-MMA awasebenzi futhi aphephile ukuze asetshenziswe ekugcineni. Kodwa-ke, i-monomer ngokwayo idinga ukuphathwa ngokucophelela ngenxa yokuvutha kwayo kanye nezindawo ezicasulayo. Imikhiqizo eqediwe efana ne-PMMA igunyazwe yi-FDA ukuthintana nokudla kanye nemishini yezokwelapha.

I-MMA kufanele igcinwe kanjani ukuze kugcinwe ikhwalithi?

Gcina i-MMA ezitsheni ezingangeni moya emazingeni okushisa angaphansi kuka-25°C, kude nokukhanya nokushisa ukuze uvimbele ukwenziwa kwe-polymerization ngaphambi kwesikhathi. Iziqinisi ezifana ne-hydroquinone ziyengezwa ukuze kunwetshwe impilo yeshalofu kuze kufike ezinyangeni eziyi-12.

Ingabe i-MMA ingagaywa kabusha?

Yebo, i-PMMA ethathwe ku-MMA igaywa kabusha kakhulu ngezinqubo zemishini noma zamakhemikhali, okunikela ezinhlelweni zomnotho eziyindilinga ekukhiqizeni amapulasitiki.

Uyini umehluko phakathi kwe-MMA namanye ama-acrylic monomers?

Ngokungafani ne-ethyl acrylate, i-MMA inikeza ukuqina okuphezulu nokuzinza okushisayo, okuyenza ikhetheke ezinhlelweni zokusebenza kunezinye eziguquguqukayo ezifana ne-butyl acrylate.

Ingabe i-MMA inawo umthelela kwezemvelo?

Ukukhiqizwa kwe-MMA kuhilela izinyathelo ezidinga amandla amakhulu, kodwa izinsiza zesimanje zinciphisa ukukhishwa kwegesi. I-PMMA egaywe kabusha inciphisa izidingo zezinto ezingakaze zenzeke, yehlise i-carbon footprint.
