2-Hydroxyethylmethacrylate CAS:868-77-9

Ponena za kagwiritsidwe ntchito ka 2-Hydroxyethylmethacrylate ku England, imagwiritsa ntchito mitundu yosiyanasiyana m'mafakitale osiyanasiyana. Pakupanga zomatira, HEMA ndi gawo lofunikira kwambiri popanga zomatira zachipatala zomwe zimagwiritsidwa ntchito potseka mabala, kupanga zida zachipatala, ndi kulumikizana kwa mano. Kugwirizana kwake ndi zinthu zake komanso mphamvu zake zomatira zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito zomwe zimafuna kukhudzana ndi khungu komanso kuvala kwa nthawi yayitali. Pankhani yopaka, HEMA imathandizira pakupanga zomatira zochiritsika ndi UV, zomwe zimagwiritsidwa ntchito m'malo monga zomatira zamagalimoto, zomalizidwa ndi matabwa, ndi zomatira zamagetsi. Zomatira izi zimapereka kuchira mwachangu, kumamatira bwino, komanso kukana zinthu za mankhwala ndi zachilengedwe, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito movutikira. Kuphatikiza apo, 2-Hydroxyethylmethacrylate imagwiritsidwa ntchito kwambiri popanga ma hydrogel a ma lens olumikizana, zomwe zimapangitsa kuti madzi azisungidwa bwino komanso mpweya wokwanira ulowe m'maso zomwe zimafunikira kuti maso aziwoneka bwino komanso otetezeka. Kugwirizana kwake ndi zinthu zake komanso mphamvu zake zowunikira zimapangitsa kuti ikhale chinthu chofunikira kwambiri pakugwiritsa ntchito maso, kuonetsetsa kuti ovala ma lens ndi omasuka komanso omasuka. Kuphatikiza apo, HEMA imagwiritsidwanso ntchito popanga ma polima apadera omwe amagwiritsidwa ntchito mu zipangizo zamano, zida zowunikira, ndi zida zamankhwala. Kusinthasintha kwake komanso kugwirizana kwake ndi ma monomers ena kumalola kusintha ndi kupanga zipangizo zapamwamba zomwe zimagwirizana ndi zofunikira zinazake zogwirira ntchito, kupereka mayankho pazosowa zosiyanasiyana zamalonda ndi zamafakitale.
