Whakataki hua me nga ahuatanga

Ko Styrene, he puhui pararopi, ko te tauira matū ko C8H8, ko te irahiko o te vinyl me te benzene ring conjugate, he kore e rewa i roto i te wai, he wairewa i roto i te ethanol, ether me etahi atu whakarewa waro, he monomer nui o te kapia waihanga, te katote whakawhiti katote me te rapa waihanga.

whakamahi

Ko te whakamahinga tino nui ko te rapa waihanga me te monomer kirihou, i whakamahia hei whakaputa rapa styrene butadiene, polystyrene, polystyrene foam;Ka whakamahia ano hoki ki te whakakotahi me etahi atu monomers ki te hanga kirihou miihini he rereke nga whakamahinga.Pērā me te acrylonitrile, butadiene copolymer ABS kapia, e whakamahia nuitia ana i roto i nga momo taputapu whare me te umanga;Ko te SAN copolymerized me te acrylonitrile he kapia me te atete paanga me te tae kanapa.Ko te SBS copolymerized ki te butadiene he momo rapa thermoplastic, e whakamahia nuitia ana hei polyvinyl chloride, polypropylene modifier.
Ko te nuinga o te Styrene e whakamahia ana i roto i te hanga o te raupapa styrene me te styrene BUTADIene rapa, ko tetahi o nga rauemi mata mo te hanga o te katote whakawhiti katote me te rongoa, hei taapiri, ka taea hoki te whakamahi i te styrene i roto i te rongoa, te tae, te pesticide me te tukatuka kohuke. me etahi atu ahumahi.3. Whakamahinga:
Mo te mahi pai, ka tūtohu kia taapirihia i muri i te waimehatanga.Ko te nui o te wai e whakamahia ana ka whakawhirinaki te nuinga ki te punaha tono.Me whakatau e te kaiwhakamahi te nui pai ma te whakamatautau i mua i te whakamahi.s.

mōkihi me te kawe

B. Ka taea te whakamahi i tenei hua ,200KG, 1000KG oko kirihou.
C. Roakina kua hiritia ki te waahi matao, maroke me te whai hau i roto i te whare.Me tino hiri nga ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me pai te hiri o tenei hua i te wa e kawe ana kia kore ai te makuku, te kawakawa kaha me te waikawa, te ua me etahi atu poke kia kore e uru.
