Polyvinyl chloride (PVC)

Na nkwusioru polymerization nke vinyl chloride, usoro a chụsasịrị nwere mmetụta kpọmkwem na ngwaahịa, PVC resin, na àgwà nke nhazi ya na ngwaahịa. Hydroxypropyl MethylCellulose na-enyere aka melite thermal nkwụsi ike nke resin na ịchịkwa urughuru size nkesa (n'ikwu ya n'ụzọ ọzọ, gbanwee njupụta PVC), na ego ya bụ 0.025% -0.03% nke PVC mmepụta. PVC resin mere si elu mma Hydroxypropyl MethylCellulose ọ bụghị naanị nwere ike hụ na arụmọrụ akara na mba ụkpụrụ, ma nwekwara ike na-ezi pụtara nkịtị Njirimara, magburu onwe urughuru Njirimara na magburu onwe agbaze rheological omume.

PVC bụ ihe na-adịgide adịgide na ogologo oge nke a pụrụ iji mee ihe n'ụdị dị iche iche, ma ọ bụ nke siri ike ma ọ bụ na-agbanwe agbanwe, na-acha ọcha ma ọ bụ oji na ụdị dịgasị iche iche nke agba n'etiti.

Na mmepụta nke resins sịntetik, dị ka polyvinyl chloride (PVC), polyvinylidene chloride, na copolymers ndị ọzọ, polymerization nkwusioru bụ nke a na-ejikarị eme ihe na ọ ghaghị ịbụ monomers hydrophobic na-adịghị agbanwe agbanwe kwụsịtụrụ na mmiri. Dị ka polymers soluble mmiri, ngwaahịa Hydroxypropyl MethylCellulose nwere ọmarịcha ọrụ elu yana ọrụ dị ka ihe nchebe colloidal. Hydroxypropyl MethylCellulose nwere ike igbochi irighiri ihe polymeric nke ọma imepụta na agglomeration. Ọzọkwa, ọ bụ ezie na Hydroxypropyl MethylCellulose bụ polymer soluble mmiri, ọ nwere ike ịdị ntakịrị soluble na hydrophobic monomers ma nwee ike ịbawanye monomer porosity maka mmepụta nke polymeric particles.
