Zogulitsa za QualiCell Hydroxypropyl Methyl Cellulose HPMC zitha kusintha ndi izi mu PVC:
·ma suspending agents omwe amagwiritsidwa ntchito kwambiri.
· Imawongolera kukula kwa tinthu ndi kugawa kwawo
· Zimakhudza porosity
· Kutanthawuza kulemera kwakukulu kwa PVC.
Cellulose ether for Polyvinyl Chloride (PVC)
Polyvinyl Chloride (PVC) ndi polima yachuma komanso yosunthika ya thermoplastic yomwe imagwiritsidwa ntchito kwambiri pantchito zomanga ndi zomangamanga kuti ipange mbiri yapakhomo ndi zenera, mapaipi (zakumwa ndi madzi otayira), waya ndi chingwe chotchingira, zida zamankhwala, ndi zina zambiri. zinthu ndi voliyumu pambuyo polyethylene ndi polypropylene.
PVC imagwiritsidwa ntchito kwambiri m'mafakitale, ukadaulo ndi ntchito zatsiku ndi tsiku kuphatikiza kugwiritsidwa ntchito ponseponse pomanga, zoyendera, zonyamula, zamagetsi / zamagetsi ndi ntchito zaumoyo.
Mu kuyimitsidwa polymerization wa vinilu kolorayidi, ndi omwazika dongosolo zimakhudza mwachindunji mankhwala, PVC utomoni, ndi pa khalidwe la processing ndi mankhwala. Hydroxypropyl MethylCellulose kumathandiza kusintha bata matenthedwe utomoni ndi kulamulira tinthu kukula kugawa (m'mawu ena, kusintha PVC kachulukidwe), ndi kuchuluka kwake nkhani 0.025% -0,03% ya kupanga PVC. PVC utomoni wopangidwa kuchokera apamwamba Hydroxypropyl MethylCellulose osati kuonetsetsa mzere ntchito ndi mfundo za mayiko, komanso akhoza kukhala ndi makhalidwe abwino zooneka thupi, kwambiri tinthu katundu ndi khalidwe losungunuka bwino rheological kusungunuka.
PVC ndi chinthu chokhazikika komanso chokhalitsa chomwe chingagwiritsidwe ntchito pazinthu zosiyanasiyana, zokhazikika kapena zosinthika, zoyera kapena zakuda ndi mitundu yambiri yamitundu pakati.
Popanga utomoni wopangira, monga polyvinyl chloride (PVC), polyvinylidene chloride, ndi ma copolymers ena, kuyimitsidwa ma polymerization ndikomwe amagwiritsidwa ntchito kwambiri ndipo kuyenera kukhala kosasintha kwa hydrophobic monomers kuyimitsidwa m'madzi. Monga ma polima osungunuka m'madzi, mankhwala a Hydroxypropyl MethylCellulose ali ndi ntchito yabwino kwambiri yapamtunda ndipo amagwira ntchito ngati zoteteza ma colloidal agents. Hydroxypropyl MethylCellulose amatha kuteteza polymeric particles kupanga ndi agglomeration. Komanso, ngakhale Hydroxypropyl MethylCellulose ndi madzi sungunuka polima, akhoza pang'ono sungunuka mu monomers hydrophobic ndi kuonjezera monomer porosity kupanga polymeric particles.
