Te whakataki me ngā āhuatanga o te hua
Ko te Styrene he matū waro, ko tōna tauira matū ko C8H8, ko te irahiko o te mowhiti vinyl me te benzene e hono ana, kāore e rewa i te wai, engari e rewa ana i roto i te etanoru, te etera me ētahi atu whakarewa waro, he monomer nui o te kapia hangai, te kapia whakawhiti katote me te rapa hangai.
whakamahi
Ko te whakamahinga nui rawa atu ko te rapa hangai me te monomer kirihou, e whakamahia ana hei hanga rapa styrene butadiene, polystyrene, pahuka polystyrene; e whakamahia ana hoki hei whakakotahi me ētahi atu monomer hei hanga kirihou hangarau o ngā whakamahinga rerekē. Pērā i te acrylonitrile, te butadiene copolymer ABS resin, e whakamahia whānuitia ana i roto i ngā momo taputapu whare me ngā ahumahi; ko te SAN copolymerized ki te acrylonitrile he resin he ātete ki te pānga me te tae kanapa. Ko te SBS copolymerized ki te butadiene he momo rapa thermoplastic, e whakamahia whānuitia ana hei polyvinyl chloride, polypropylene modifier.
Ko te Styrene te mea e whakamahia nuitia ana i roto i te hanga kapia raupapa styrene me te rapa styrene BUTADIene, ko tētahi o ngā rauemi mata mō te hanga kapia whakawhiti katote me te rongoā, hei tāpiri, ka taea hoki te whakamahi i te styrene i roto i te rongoā, te tae, te tukatuka patupatu me te kohuke me ētahi atu ahumahi. 3. Te Whakamahinga:
Mō te mahi pai rawa atu, e taunakihia ana kia tāpirihia i muri i te whakaranu. Ko te nui o te wai e whakamahia ana e whakawhirinaki ana ki te pūnaha tono. Me whakatau e te kaiwhakamahi te nui pai rawa atu mā te whakamātautau i mua i te whakamahinga.
mōkihi me te kawe
B. Ka taea te whakamahi i tēnei hua, 200KG, 1000KG oko kirihou.
C. Penapenahia kia hiri ki roto i te wāhi hauhautanga, maroke, me te hauhautanga. Me hiri rawa ngā ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me hiri pai tēnei hua i te wā e kawe ana kia kore ai e uru te makuku, te kawakore me te waikawa kaha, te ua me ētahi atu poke.
