Hydroxypropyl MethylCellulose na-eji na PVC

Hydroxypropyl Methylcellulose (HPMC) na-achọta ojiji dị iche iche na mmepụta na nhazi nke polyvinyl chloride (PVC). Nke a bụ ụfọdụ ngwa ngwa HPMC na PVC:

1. Enyemaka nhazi: A na-eji HPMC dị ka ihe enyemaka nhazi n'ichepụta ogige PVC na ngwaahịa. Ọ na-eme ka ihe ndị na-asọ asọ nke PVC na-emepụta n'oge nhazi, na-eme ka extrusion, ịkpụzi, na nhazi usoro. HPMC na-ebelata esemokwu n'etiti ihe ndị dị na PVC, na-eme ka usoro nhazi na ibelata oriri ike.
2. Mgbanwe mmetụta: N'ime usoro PVC, HPMC nwere ike rụọ ọrụ dị ka ihe mgbanwe mgbanwe, na-emeziwanye ike na nguzogide mmetụta nke ngwaahịa PVC. Ọ na-enyere aka ịbawanye ductility na mgbaji siri ike nke ogige PVC, na-ebelata ohere nke ịda mbà n'obi na imeziwanye arụmọrụ ngwaahịa na ngwa ebe nguzogide mmetụta dị oke mkpa.
3. Stabilizer: HPMC nwere ike ije ozi dị ka onye na-emezi ihe na PVC, na-enyere aka igbochi mmebi nke polymer n'oge nhazi na ojiji. Ọ nwere ike igbochi mmebi ọkụ, mmebi UV, na mmebi oxidative nke PVC, na-agbatị ndụ ọrụ na ịdịte aka nke ngwaahịa PVC kpughere ọnọdụ gburugburu ebe obibi siri ike.
4. Ihe nchikota: A na-eji HPMC eme ihe dị ka ihe eji eme ihe na mkpuchi PVC, ihe mkpuchi na ihe mkpuchi. Ọ na-enyere aka melite adhesion nke PVC mkpuchi na substrates, na-enye njikọ siri ike ma na-adịgide adịgide. HPMC na-akwalitekwa njikọta na imepụta ihe nkiri nke ihe mkpuchi na mkpuchi nke PVC, na-eme ka arụmọrụ ha na ịdịte aka.
5. Onye nnọchi anya ndakọrịta: HPMC na-eje ozi dị ka onye na-ahụ maka ndakọrịta na ụdị PVC, na-akwalite mgbasa na ndakọrịta nke mgbakwunye, ihe ndozi na pigmenti. Ọ na-enyere aka igbochi agglomeration na idozi ihe mgbakwunye, na-ahụ maka nkesa otu n'ime matriks PVC. HPMC na-emekwa ka ịdị n'otu na ịdị n'otu nke ogige PVC dị mma, na-ebute ngwaahịa nwere akụrụngwa na arụmọrụ na-agbanwe agbanwe.
6. Viscosity Modifier: Na nhazi PVC, HPMC nwere ike iji dị ka ihe mgbanwe viscosity iji dozie viscosity na rheological Njirimara nke usoro PVC. Ọ na-enyere aka ịchịkwa omume na-asọpụta na nhazi nhazi nke ogige PVC, melite njikwa usoro na àgwà ngwaahịa.

Hydroxypropyl Methylcellulose (HPMC) na-arụ ọrụ bara uru na mmepụta, nhazi, na arụmọrụ nke polymers na ngwaahịa PVC. Ngwongwo ya na ihe bara uru na-eme ka ọ bụrụ ihe mgbakwunye a na-ejikarị eme ihe na ngwa PVC dị iche iche, na-enye aka na nhazi nhazi, arụmọrụ na ịdịte aka.
