Ngā Āhuatanga matū:

Ko te Methyl methacrylate he wai karekau he tae, he puhoi me te mura. Kiato pātahi 0.9440. ira whakarewa – 48℃. Kohuatanga 100~101℃. Ira hiko (kapu tuwhera) 10℃. Taupū Refactive 1. 4142. pehanga kohu (25.5 ℃) 5.33kPa. wairewa i roto i te waihā, te etera, te acetone me etahi atu whakarewa pararopi. He iti te whakarewa ki te ethylene glycol me te wai. He ngawari te polymerized i te aroaro o te marama, te wera, te iraruke katote me te whakakorikori.

Taupānga:

1.Ko te Methyl methacrylate he matū whakahiato karekau e whakamahia ana ki te hanga i te pepa kiriaku maka, whakaehunga kiriaku, me te whakarewa me te kapia tangohanga.

2.I roto i te hanga o te kapia methacrylate me te kirihou. Ka whakawhitia te Methyl methacrylate ki nga methacrylate teitei ake penei i te n-butyl methacrylate, 2-ethylhexylmetacrylate ranei.

3.Ka whakamahia te monomer methyl methacrylate ki te hanga polymers me te copolymers methylmethacrylate, polymers me te copolymers ka whakamahia hoki ki te wai, whakarewa, me nga paninga mata kaore i rewa, whakapiri, hiri, hiako me te pepa paninga, waituhi, whakakoi papa, mutu kakano, porowhita niho, me te whakamarumaru o te maihao i roto i te rauropi kiriaku, me te raima hiako o te maihao. me nga whakauru hu orthotic. Ka whakamahia ano te Methyl methacrylate hei rauemi timata ki te hanga i etahi atu esters o te waikawa methacrylic.

4.Ko nga maara mo te werohanga me te pupuhi pupuhi mo te tino maamaa, te huarere me te aukati i te waahi ka whakamahia ki te rama, ki nga taputapu tari me te hikohiko (whakaata waea pūkoro me nga taputapu hi-fi), te hanga me te hanga (whakapapa me nga matapihi), te hoahoa o naianei (nga taonga, whakapaipai me nga taputapu tepu), waka me te kawe waka (rama me nga taputapu taputapu), nga taputapu hauora me te haumaru o te whare. peihana).

5.Ko nga whakarereketanga paanga mo te polyvinyl chloride maamaa maamaa.
