Ko te kapia synthetic he puhui polymer, ka hangaia ma te whakakotahi i nga rauemi mata ngota iti - monomers (pēnei i te ethylene, propylene, vinyl chloride, me etahi atu) ki roto i nga macromolecules ma te polymerization.Ko nga tikanga polymerization e whakamahia nuitia ana i roto i te ahumahi ko te polymerization te nuinga, te polymerization whakatārewatanga, te polymerization emulsion, te polymerization otinga, te polymerization slurry, te polymerization hau, me etahi atu.I nga ra o mua, ko te nuinga o nga hua ta waro me te konupūmā carbide calcium carbide.Inaianei ko te nuinga o nga hua hinu me te hau maori, penei i te ethylene, propylene, benzene, formaldehyde me te Urea.
Te whakahiato ontology
Ko te polymerization nui he tukanga polymerization e polymerized ai nga monomers i raro i te mahi a te kaitakiri, te wera ranei, te marama, me te rauropi me te kore e taapiri atu i etahi atu papaaoho.Ko te ahuatanga ko te mea he parakore te hua, kaore he wehewehenga uaua me te purenga e hiahiatia ana, he ngawari noa te mahi, he nui te tere o te whakamahi i nga taputapu whakaputa.Ka taea e ia te whakaputa i nga hua o te kounga teitei penei i nga paipa me nga pereti, no reira ka kiia hoki ko te polymerization poraka.Ko te ngoikoretanga ko te piki haere tonu o te viscosity o te rauemi me te ahunga whakamua o te tauhohenga polymerization, he uaua te whakaranu me te whakawhiti wera, a ko te pāmahana o te reactor ehara i te mea ngawari ki te whakahaere.Ko te tikanga polymerization nuinga e whakamahia ana i roto i te hanga o nga kapia penei i te polyadditional methyl acrylate (e mohiotia ana ko te plexiglass), te polystyrene, te polyethylene iti-iti, te polypropylene, te polyester me te polyamide.
polymerization whakatārewatanga
Ko te polymerization whakatārewatanga e pā ana ki te tukanga polymerization i marara ai te monomer ki roto i nga rūrūtia i raro i te mahi o te whakakorikori miihini, te wiri ranei me te dispersant, a ko te nuinga o te waa ka whakairihia ki te wai, no reira ka kiia hoki ko te polymerization.Ko nga ahuatanga ko: he nui te wai i roto i te reactor, he iti te viscosity o te rauemi, he ngawari ki te whakawhiti i te wera me te whakahaere;i muri i te polymerization, me haere noa i roto i te wehewehenga ngawari, te horoi, te whakamaroke me etahi atu tukanga kia whiwhi ai i te hua kapia, ka taea te whakamahi tika mo te mahi hangai;he parakore te hua, he rite.Ko te ngoikoretanga ko te kaha o te hanga o te reactor me te ma o te hua kaore i te pai ki te tikanga polymerization nui, a kaore e taea te whakamahi i te tikanga tonu mo te whakaputa.Ka whakamahia te polymerization whakatārewatanga i roto i te ahumahi.
