Styrene me te tono

He aha te styrene

Ko te Styrene he matū matū tino nui, ko tana tātai matū ko C8H8, he mura ahi, he matū kino, mai i te benzene parakore me te whakahiato ethylene.Kei te nuinga whakamahia te reira i roto i te hanga o te polystyrene pahuka i (EPS), polystyrene (PS), ABS me ētahi atu resins waihanga me te styrene butadiene rapa (SBR), SBS elastomer, hua whakararo e whakamahia whānuitia i roto i te hanga i te whakamatao, hanga waka, taputapu whare, hanga takawairore, pueru, pepa, takai hu me etahi atu ahumahi.I tua atu, ka taea hoki te whakamahi hei rongoa, pesticide, waikano, takawaenga kohuke, he maha nga whakamahinga.Ko nga pärönaki Styrene te tuawha o nga pärönaki ethylene NUI i muri i te polyethylene, te ethylene oxide me te vinyl chloride, a ko te hanga o nga kapia styrene he tuarua anake ki te polyethylene (PE) me te polyvinyl chloride (PVC).

1. Raina Ahumahi

Ko nga ahuatanga o te mekameka ahumahi styrene ka taea te whakarapopoto hei "hinu o runga me te waro, te rapa o raro" - te mekameka o runga o te hinu hinu matū me te mekameka ahumahi matū waro, te heke o te reinga waihanga me te ahumahi rapa waihanga.

2.Whakamahia

I te awa whakarunga o te styrene mo te ethylene me te benzene parakore, ki raro mo te styrene, EPS foam polystyrene, acrylonitrile – butadiene – styrene terpolymer, SBR/SBL styrene butadiene rapa, styrene latex hei dispersant whakararo.Ko te EPS, ABS me te PS te tono nui rawa atu o te styrene ki raro, neke atu i te 70%.I tua atu i tenei waahanga o te tono o raro, ka whakamahia ano te styrene i roto i te rongoa, te tae, te pesticide, te tukatuka kohuke me etahi atu ahumahi.

Ko te polystyrene pahuka EPS he mea hanga mai i te styrene me nga hua taapiri a te kaihoko pahuka, he iti, he iti te kawe i te waiariki, he iti te whakauru o te wai, he wiri wiri, he wera wera, he tangi oro, he makuku-tohu, he anti-wiri, he pai te tatari mo te mahi dielectric. mo te painga, ka whakamahia te nuinga mo te hanga i nga rawa whakamarumaru, nga taputapu hiko / taputapu tari mo nga taputapu kapi me te kapu inu kotahi mo te wa kotahi, me era atu.

PS polystyrene Kei te whakamahia whānuitia i roto i te ahumahi marama, ina koa mo te whakapaipai o ia ra, tohu rama me te kohinga hua.I tua atu, ko te polystyrene he taonga whakamaarama pai i roto i te waahanga hiko, na reira ka taea hoki te whakamahi ki te hanga i nga momo anga taputapu, nga waahanga taputapu me nga purongo capacitive.

Ko te kapia ABS he mea hanga mai i te styrene, te acrylonitrile, te butadiene terpolymer, he pai rawa atu te awangawanga, te aukati matū me nga taonga hiko, he taonga anga tino pai, te nuinga e whakamahia ana i roto i nga taputapu kaainga / tari tari anga me nga taputapu, papatohu motuka / tatau / arai.
