CAS 80-62-6 99.9% MMA methyl methacrylate wai

Whakaahuatanga Poto:

Methyl methacrylate(MMA)                              

Ko te Methyl methacrylate (MMA) he puhui waro me te tauira matū C5H8O2.He wai karekau he tae, he iti te wairewa i roto i te wai, me te wairewa i roto i te nuinga o nga whakarewa pararopi penei i te ethanol.I whakamahia te nuinga hei monomer o te plexiglass, engari ka whakamahia ano hoki i roto i te hanga o etahi atu resins, kirihou, paninga, adhesives, lubricants, kaihoko rahi mo te rakau me te puru, me te pepa moata.

Panui mahi: mahi kati, whakakaha i te hau.Me whakangungu motuhake nga Kaihautu me te tino whai i nga tikanga whakahaere. E taunaki ana kia mau nga kaiwhakahaere ki te whakakakahu i nga respirators tātari whaiaro (hawhe kopare), he karumaru haumaru matū, kakahu mahi anti-static me te hinu rapa- karapu ātete.Kia matara atu i te ahi me nga puna wera, ka tino aukatia te kai paipa i te waahi mahi.Whakamahia nga punaha me nga taputapu whakamaarama-pahū.Aukati i nga kohu kia kore e rere ki roto i te hau o te waahi mahi.Kati te pa atu ki nga waikura, waikawa, turanga, haukoi.I te wa e whakahaere ana, me ngawari te utaina me te wetewete kia kore ai e kino te takai me nga ipu. Ka mau ki te momo me te maha o nga taputapu patu ahi me nga taputapu maimoatanga ohorere.Ko nga ipu putua he toenga kino.

Awhina tuatahi

Kiri: Tango i nga kakahu poke ka horoia te kiri ki te hopi me te wai.

Kanohi: Hikina nga kamo ka horoi ki te wai rere, ki te tote noa ranei.rapu hauora.

Inhalation: Kia tere te waiho i te waahi ki te hau hou.Kia tuwhera tonu te huarahi hau.Mena he uaua te manawa, hoatu te hāora.Ki te mutu te manawa, hoatu te manawa horihori tonu.Haere tonu ki te hōhipera.

Te horomia: Inuhia he wai mahana kia nui te ruaki.Haere tonu ki te hōhipera.
