Whakatarewa i te Polymerization o (HPMC) Hydroxypropyl Methylcellulose whakamahi mo PVC

Ka mau tatou i te tapatahi me te wikitoria-win hei kaupapa whakahaere, me te manaaki i nga umanga katoa me te tino whakahaere me te manaaki.

Ko te Hydroxypropyl Methylcellulose hei kaiwehewehe, ko nga hua i whiwhi he matūriki hanganga me nga matūriki, he pai te ahua me te pai o te mahi tukatuka. Heoi, ko te whakamahinga o Hydroxypropyl Methylcellulose anake ka whai waahi ki te pai o te rerekee o te kapia ahakoa. He kino te mahi katoa o te kapia. Ko te whakamahinga o te hydroxypropyl methylcellulose me te maha o nga tohu waipiro o te waipiro polyvinyl ka pai ake te mahi o nga hua, te kounga ngawari ki te whakahaere me te wa ano ka whakaiti i te utu. Ko te kaihoko marara te take matua e awe ana i te ahua matūriki o te kapia polyvinyl chloride. Ko te iti ake o te mata o te wairewa wai o nga marara whanui me te awangawanga atanga me te Vinyl chloride monomer, ka pai ake te mararatanga o nga pata VCM. Na ka iti ake te diameter matūriki o te PVC resin. Ko te kaha ake o te whakamarumaru o te kaihoko whakamarara, ka tata atu nga matūriki kapia PVC kua whiwhi, ka iti ake te porosity. He uaua ano hoki te whakakotahitanga o waenga, no reira he ngawari te hanga kapia.

Hei tauira, i roto i te punaha whakamararatanga puhui o te PVA me te HPC, ko te teitei ake o te tohu waipiro o te PVA, ko te nui ake o te awangawanga o te mata o te wairewa wai ka kaha ake te kaha o te tiaki, i te mea ko tetahi kukū o te hydroxypropyl methylcellulose kei roto. he painga marara pai. Na reira, te whakamahi i te PVA me te tohu waipiro teitei hei mea tuatahi

te marara, me te whakahuihui a

etahi nui o te hydroxypropyl methylcellulose

hei kaihoko marara mo te polymerization whakatārewatanga, he maamaa ake te whakarite i te kapia PVC ka taea te whakatutuki i nga whakaritenga o te morphology matūriki. Hei tauira, i roto i te punaha whakamararatanga puhui o te PVA me te HPC, ko te teitei ake o te tohu waipiro o te PVA, ko te nui ake o te awangawanga o te mata o te wairewa wai ka kaha ake te kaha o te tiaki, i te mea ko tetahi kukū o te hydroxypropyl methylcellulose kei roto. he painga marara pai.
