Gịnị bụHydroxypropyl Methyl Cellulose (HPMC)?
Hydroxypropyl methyl cellulose, nke a na-akpọkarị HPMC, bụ polymer synthetic, nke nwere ike ịsacha mmiri, nke sitere na cellulose. A na-emepụta ya site na mgbanwe kemịkalụ nke cellulose, polysaccharide na-emekarị nke a na-ahụ na mgbidi cell nke osisi. Mgbanwe ahụ gụnyere iwebata hydroxypropyl na methyl otu n'ime ọkpụkpụ azụ cellulose, na-eme ka ngwakọta nwere ihe pụrụ iche dabara adaba maka ngwa dị iche iche.

Njirimara na njirimara HPMC:

Mmiri Solubility: Otu n'ime njirimara nkọwa nke HPMC bụ oke mmiri mmiri ya. Mgbe agwakọtara ya na mmiri, HPMC na-etolite ngwọta doro anya, viscous, na-eme ka ọ dị mfe itinye n'ime usoro mmiri dị ka adhesives.
Ikike imepụta ihe nkiri: HPMC nwere ikike imepụta ihe nkiri na-agbanwe agbanwe na nke jikọtara ọnụ mgbe akpọnwụchara. Ihe onwunwe a bara uru karịsịa na ngwa nrapado, ebe a na-achọ njikọ siri ike na otu.
Adhesion na Cohesion: HPMC na-egosipụta ma nrapado na ihe jikọrọ ọnụ, na-enyere ya aka ịrapagidesi ike na ihe dị iche iche ma na-ejigide ike dị n'ime n'ime oyi akwa.
Njikwa Rheological: HPMC na-eje ozi dị ka ihe mgbanwe rheology na usoro nrapado, na-emetụta viscosity, omume ịgba ọsọ, na thixotropy. Nke a na-enye ohere maka njikwa ziri ezi na njirimara ngwa ma na-eme ka nhazi nke ọma n'oge a na-ewu.
Ngwa nke HPMC na Ngwunye Glue Layering:
HPMC na-ahụta ojiji a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu, ọkachasị n'ichepụta ihe nrapado ụlọ maka ebumnuche dị iche iche:

Adhesives Taịlị:HPMCbụ isi ihe dị na tile adhesives, ebe ọ na-arụ ọrụ dị ka ihe nkedo, na-enye adhesion n'etiti tile na substrates. Ihe ndị na-emepụta ihe nkiri ya na-eme ka e nwee njikọ na-adịgide adịgide nke nwere ike iguzogide nrụgide ígwè ọrụ na ihe ndị metụtara gburugburu ebe obibi.
Cement Renders and Plasters: Na ciment renders na plasters, HPMC na-arụ ọrụ dị ka ihe na-eme ka ihe na-esi ísì ụtọ na enyemaka njide mmiri. Ọ na-eme ka arụ ọrụ dịkwuo mma, na-eme ka adhesion na ihe ndị dị n'ime ya dịkwuo mma, na-egbochi nkwụsị ma ọ bụ mgbawa n'oge ngwa na ihicha.
Ngwakọta nkwonkwo na ihe mkpuchi: A na-eji ihe ndị na-emepụta ihe na-emepụta ihe na HPMC na-emeju oghere, mgbawa, na nkwonkwo na ihe owuwu. Usoro ndị a na-enye ezigbo adhesion, mgbanwe na ịdịte aka, na-eme ka akara na-adịte aka na njedebe.
