Ka taea e nga hua QualiCell Hydroxypropyl Methyl Cellulose HPMC te whakapai ake ma nga taonga e whai ake nei i roto i te PVC:
· te nuinga o te whakamahi i nga apiha whakatari.
·Ka whakahaere i te rahi matūriki me te tohatoha
·Ka awe i te porosity
· Ka tautuhi i te taumaha nui o te PVC.
Etera Cellulose mo te Polyvinyl Chloride (PVC)
Ko te Polyvinyl Chloride (PVC) he polymer thermoplastic ohaoha me te maha e whakamahia nuitia ana i roto i te hanga whare me te ahumahi hanga ki te whakaputa i nga korero tatau me te matapihi, nga paipa (inu me te wai para), te waea me te tauera taura, nga taputapu rongoa, me era atu. rauemi ma te rōrahi i muri i te polyethylene me te polypropylene.
Ka whakamahia nui te PVC puta noa i te whānuitanga o nga mahi ahumahi, hangarau me nga mahi o ia ra tae atu ki te whakamahi whanui i roto i te hanga whare, te kawe, te takai, te hiko/hiko me nga tono hauora.
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 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.
