Kedu ka HPMC si arụ ọrụ na adhesives tile na grouts?

Hydroxypropyl Methylcellulose (HPMC) bụ ihe mgbakwunye dị iche iche nke a na-ejikarị na tile adhesives na grouts maka ike ya iji melite arụmọrụ yana ịrụ ọrụ. Ngwongwo ya na-enye aka n'akụkụ dị iche iche nke usoro nrapado na grouting, na-emetụta ihe ndị dị ka ike njikọ, njide mmiri, oge na-emeghe, nkwụsị sag, na ogologo oge dum. Ịghọta ka HPMC si arụ ọrụ na ihe ndị a chọrọ ịbanye n'ime usoro kemịkalụ ya, mmekọrịta ya na mmiri, yana ọrụ ya na usoro nrapado na grouting.

Ọdịdị kemịkalụ nke HPMC:

HPMC bụ cellulose ether nke sitere na cellulose eke, polysaccharide dị na osisi.
Ọdịdị kemịkal ya nwere agbụ azụ cellulose nwere hydroxypropyl na methyl nnọchi.
Ogo nke nnọchi (DS) nke otu ndị a na-ekpebi njirimara nke HPMC, gụnyere solubility ya, ikike njide mmiri, na omume rheological.

Ndokwa mmiri:

HPMC nwere njikọ dị elu maka mmiri n'ihi ọdịdị hydrophilic ya, na-eme njikọ hydrogen na ụmụ irighiri mmiri.
Na tile adhesives, HPMC na-arụ ọrụ dị ka onye na-ejigide mmiri, na-agbatị oge oghere nke nrapado.
Ogologo oge a na-emeghe na-enye ohere maka ịrụ ọrụ ka mma yana mma nrapado site na igbochi ihicha ngwa ngwa nke nrapado.

Ịrụ ọrụ emelitere:

Ọnụnọ nke HPMC na tile adhesives na grouts na-eme ka ọrụ ha dịkwuo mma site n'ịkwalite njirimara rheological ha.
HPMC na-arụ ọrụ dị ka onye na-agba ume na ihe nkwụsi ike, na-enye omume pseudoplastic na nrapado ma ọ bụ grout.
Nke a pseudoplasticity na-ebelata ịda mbà ma ọ bụ ịda mbà n'obi n'oge ngwa, na-eme ka mkpuchi dị mma na ịdị n'otu.

Ike njikọta emelitere:

HPMC na-enye aka na ike njikọta nke nrapado tile site na imeziwanye kọntaktị n'etiti nrapado na mkpụrụ.
Ngwongwo njide mmiri ya na-eme ka hydration zuru oke nke ihe cimenti, na-akwalite ọgwụgwọ kwesịrị ekwesị na adhesion.
Na mgbakwunye, HPMC nwere ike gbanwee microstructure nke nrapado, na-eme ka ihe eji arụ ọrụ ya na ike nrapado.

Nguzogide Sag:

Ọdịdị pseudoplastic nke HPMC na-enye omume thixotropic iji tile adhesives na grouts.
Thixotropy na-ezo aka na ihe onwunwe nke ịghọ obere viscous n'okpuru nrụgide shear na ịlaghachi na viscosity dị elu mgbe ewepụrụ nrụgide ahụ.
Omume thixotropic a na-eme ka nguzogide sag dị mma n'oge ngwa kwụ ọtọ, na-egbochi nrapado ma ọ bụ grout ka ọ ghara ịdaba na mkpụrụ tupu ọ gwọọ ya.

Ọdịgidere na arụmọrụ:

HPMC na-akwalite ịdịte aka na arụmọrụ nke nrapado tile na grouts site n'inye nguzogide mmiri ka mma yana mbelata mbelata.
Ngwongwo ejigide mmiri ya na-ebelata ihe ize ndụ nke ihicha akaghi aka na mgbawa, na-ebute nrụnye siri ike na ogologo oge.
HPMC nwere ike itinye aka na nguzobe nke nnukwu microstructures na-edoghị anya, na-eme ka iguzogide ntinye mmiri na nrụgide arụ ọrụ.

Hydroxypropyl Methylcellulose (HPMC) na-arụ ọrụ dị mkpa na adhesives tile na grouts site na imeziwanye arụmọrụ ha, ike njikọta, nguzogide sag, na ịdịte aka. Njirimara njide mmiri ya, jikọtara ya na mmetụta rheological ya, na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa maka ịrụ ọrụ kacha mma na ịdị mma na nrụnye tile.
