Polyvinyl Chloride (PVC)

I roto i te polymerization whakatārewatanga o te vinyl pūhaumāota, te pūnaha marara he pānga tika i runga i te hua, PVC resin, me te ki runga ki te kounga o ona tukatuka me ngā hua. Ka awhina a Hydroxypropyl MethylCellulose ki te whakapai ake i te pumau o te waiariki o te kapia me te whakahaere i te tohatoha rahi o te matūriki (i etahi atu kupu, whakatikahia te kiato PVC), a ko te nui o te 0.025% -0.03% o te hanga PVC. Ko te kapia PVC i hangaia mai i te Hydroxypropyl MethylCellulose o te kounga teitei e kore e taea anake te whakarite i te raina mahi me nga paerewa o te ao, engari he pai ano te ahua o te tinana, nga ahuatanga matūriki tino pai me te pai o te whanonga rheological rewa.

Ko te PVC he mea tino roa me te roa o te waa ka taea te whakamahi i roto i nga momo tono, ahakoa he maamaa, he ngawari ranei, he ma, he pango ranei me te tini o nga tae kei waenganui.

I roto i te hanga kapia waihanga, penei i te polyvinyl chloride (PVC), polyvinylidene chloride, me etahi atu copolymers, ko te polymerization whakatārewa te mea tino whakamahia, me he monomers hydrophobic invariant kua whakatarewahia ki te wai. Hei polymers wairewa-wai, Hydroxypropyl MethylCellulose hua he mahi mata pai, me te mahi hei apiha colloidal tiaki. Ka taea e te Hydroxypropyl MethylCellulose te aukati i nga matūriki polymeric mai i te whakaputa me te agglomeration. I tua atu, ahakoa ko te Hydroxypropyl MethylCellulose he polymer wairewa wai, ka taea te rewa paku i roto i nga monomers hydrophobic me te whakanui ake i te porosity monomer mo te hanga matūriki polymeric.
