Suspension Polymerization of (HPMC) Hydroxypropyl Methylcellulose sebelisa bakeng sa PVC

Re nka botšepehi le win-win e le molao-motheo oa ts'ebetso, 'me re tšoara khoebo e' ngoe le e 'ngoe ka taolo le tlhokomelo e tiileng.

Hydroxypropyl Methylcellulose e le lisebelisoa tse arolang, lihlahisoa tse fumanoeng li na le likaroloana tse hlophisitsoeng le tse hlephileng, tse loketseng tse bonahalang le ts'ebetso e babatsehang ea ho sebetsa. Leha ho le joalo, tšebeliso ea Hydroxypropyl Methylcellulose feela e ka kenya letsoho ho feto-fetoheng ho hotle ha resin leha ho le joalo. Ts'ebetso e akaretsang ea resin e fokola. Tšebeliso ea motsoako oa hydroxypropyl methylcellulose le tekanyo e fapaneng ea alcoholysis ea polyvinyl joala e ka etsa hore ts'ebetso ea lihlahisoa e be betere, boleng bo bonolo ho laola 'me ka nako e ts'oanang bo ka fokotsa litšenyehelo. Moemeli oa ho qhalakanya ke ntho e ka sehloohong e susumetsang sebopeho sa karoloana ea resin ea polyvinyl chloride. Ha tsitsipano e kaholimo ea tharollo e nang le metsi ea li-ajenti tse qhalakanyang ka kakaretso le tsitsipano ea sefahleho e nang le Vinyl chloride monomer e nyane, ke moo marotholi a VCM a ka qhalakanngoang haholoanyane. 'Me kahoo bophara ba karoloana ea resin ea PVC e tla ba nyane. Ha matla a ts'ireletso ea moemeli ea qhalakanyang a le matla, ho tla ba le likaroloana tse haufi tsa PVC tsa resin 'me porosity e tla ba e nyane. 'Me li-intergranular coalescence le tsona li thata haholo, kahoo ho bonolo ho etsa li-resin.
