Te Whakamahi Tumuaki
Ko te Neopentanediol dimethacrylate he kaihoko honohono nui e whakamahia nuitia ana i roto i nga mara o te karaihe waro, paninga, sol-tere me nga umanga rapa.
Te takai
Pahū kirihou, tank kowiri tira ranei, 200kg te taumaha kupenga.
Te kawe me te rokiroki
A ape i te ua whiti me te nui o te pāmahana i roto i te kawe waka.Whakaorangia nga hua i roto i nga waahi makariri, marumaru me te hau, kia matara atu i te ahi.6 marama mai i te ra o te tukunga i te pāmahana rokiroki teitei o te 30 ℃.
Nga tohu tohu whanui
Ka mura! Ka timatahia te polymerization ma te poke ki te peroxides, pūhui aze, katote konganuku taumaha, tert. Amines, Scompounds. Ko te polymerization he mea whakaawehia e te marama. Ko te hauhautanga o te hau i roto i te monomer e tika ana mo te pumau. Ko te pāmahana rokiroki kaua e neke ake i te 35.
