Ho emisa Polymerization ea Hydroxypropyl Methylcellulose ka PVC

Ho emisoa ha polymerization ea Hydroxypropyl Methylcellulose (HPMC) ho Polyvinyl Chloride (PVC) ha se mokhoa o tloaelehileng.HPMC e sebelisoa haholo-holo joalo ka tlatsetso kapa mofetoleli mekhoeng ea PVC eseng joalo ka moemeli oa polymerization.

Leha ho le joalo, HPMC e ka kenngoa ka har'a metsoako ea PVC ka mekhoa ea ho kopanya moo e kopantsoeng le resin ea PVC le lisebelisoa tse ling ho finyella thepa e itseng kapa ntlafatso ea ts'ebetso.Maemong a joalo, HPMC e sebeletsa mesebetsi e fapaneng joalo ka motenya, binder, stabilizer, kapa rheology modifier.

Mona ke likarolo tse ling tse tloaelehileng tsa HPMC mekhoeng ea PVC:

1. Thickener le Rheology Modifier: HPMC e ka eketsoa ho liforomo tsa PVC ho lokisa viscosity, ho ntlafatsa litšobotsi tsa ts'ebetso, le ho ntlafatsa thepa ea phallo ea polymer e qhibilihisang nakong ea ts'ebetso.
2. Binder le Adhesion Promoter: HPMC e ntlafatsa ho khomarela pakeng tsa likaroloana tsa PVC le lisebelisoa tse ling ha ho etsoa, ​​​​ho khothalletsa homogeneity le botsitso.E thusa ho kopanya metsoako, ho fokotsa karohano le ho ntlafatsa ts'ebetso ea kakaretso ea metsoako ea PVC.
3. Tšebelisano ea Stabilizer le Plasticizer: HPMC e sebetsa e le stabilizer mefuteng ea PVC, e fana ka khanyetso ho senyeha ha mocheso, mahlaseli a UV, le oxidation.E boetse e ntlafatsa tšebelisano ea li-plasticizers tse nang le resin ea PVC, e ntlafatsa ho tenyetseha, ho tšoarella, le boemo ba leholimo ba lihlahisoa tsa PVC.
4. Impact Modifier: Lits'ebetsong tse ling tsa PVC, HPMC e ka sebetsa joalo ka phetoho ea tšusumetso, ea ntlafatsa ho tiea le ho hanyetsa ha lihlahisoa tsa PVC.E thusa ho eketsa ductility le fracture toughness ea metsoako ea PVC, ho fokotsa monyetla oa ho hlōleha ha brittle.
5. Filler le Reinforcement Agent: HPMC e ka sebelisoa e le setsi sa ho tlatsa kapa sa matlafatso mefuteng ea PVC ho ntlafatsa thepa ea mochini joalo ka matla a thata, modulus le botsitso ba sebopeho.E ntlafatsa ts'ebetso e akaretsang le semelo sa sebopeho sa lihlahisoa tsa PVC.

ha HPMC e sa tloaelehe ho etsoa polymerized le PVC ka polymerization ea ho emisoa, hangata e kenngoa ka har'a libopeho tsa PVC ka mekhoa ea ho kopanya ho finyella lintlafatso tse itseng tsa tshebetso.Joalo ka tlatsetso kapa phetoho, HPMC e kenya letsoho mefuteng e fapaneng ea lihlahisoa tsa PVC, e li etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng liindastering tse kang tsa kaho, tsa likoloi, tsa ho paka le tsa bophelo bo botle.
