Polyvinyl Chloride (PVC)

N'iji vinyl chloride eme ka ọ dị n'otu nkwụsịtụ, sistemụ ahụ gbasaara nwere mmetụta kpọmkwem na ngwaahịa ahụ, PVC resin, yana ogo nhazi ya na ngwaahịa ya. Hydroxypropyl MethylCellulose na-enyere aka ime ka resin dịkwuo mma ma chịkwaa nkesa nha mkpụrụ ahụ (n'ikwu ya n'ụzọ ọzọ, gbanwee njupụta PVC), ego ya na-abụkwa 0.025% -0.03% nke mmepụta PVC. PVC resin nke e ji Hydroxypropyl MethylCellulose dị elu mee abụghị naanị na ọ nwere ike ijide n'aka na ahịrị arụmọrụ ya kwekọrọ na ọkọlọtọ mba ụwa, kamakwa ọ nwere ike inwe ezigbo ihe onwunwe anụ ahụ, ihe onwunwe dị mma na omume rheological dị mma.

PVC bụ ihe siri ike ma na-adịgide adịgide nke enwere ike iji mee ihe dị iche iche, ma nke siri ike ma nke na-agbanwe agbanwe, nke ọcha ma ọ bụ oji na ọtụtụ agba dị iche iche n'etiti ha.

N'imepụta resin sịntetik, dịka polyvinyl chloride (PVC), polyvinylidene chloride, na copolymers ndị ọzọ, polymerization nke nkwụsịtụ bụ nke a na-ejikarị eme ihe ma ga-abụrịrị monomers hydrophobic na-adịghị agbanwe agbanwe nke a kwụnyere na mmiri. Dịka polymers mmiri na-agbaze, ngwaahịa Hydroxypropyl MethylCellulose nwere ọrụ dị mma n'elu ma na-arụ ọrụ dị ka ihe nchebe colloidal. Hydroxypropyl MethylCellulose nwere ike igbochi ihe polymeric nke ọma imepụta na ịchịkọta. Ọzọkwa, ọ bụ ezie na Hydroxypropyl MethylCellulose bụ polymer mmiri na-agbaze, ọ nwere ike ịgbaze ntakịrị na monomers hydrophobic ma nwee ike ịbawanye porosity monomer maka mmepụta nke ihe polymeric.
