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 li-additives 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 khethehileng 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.
