Ngwa nke Cellulose Ethers na Tile Adhesives

Cellulose ethers, dị ka hydroxypropyl methylcellulose (HPMC) na methyl cellulose (MC), na-arụ nnukwu ọrụ na tile nrapado formulations n'ihi na ha pụrụ iche Njirimara na vasatail ngwa. Nke a bụ ụfọdụ ngwa ethers cellulose na-ejikarị na tile adhesives:

1. Njide mmiri: Cellulose ethers na-arụ ọrụ dị ka ihe na-eme ka mmiri na-eme ka mmiri dị na tile nrapado formulations, na-eme ka ọrụ na-emeghe oge nke nrapado. Site na idowe mmiri n'ime matriks nke nrapado, cellulose ethers na-egbochi ihicha akaghi aka ma hụ na hydration zuru oke nke ihe nkedo cementious, na-eme ka adhesion na ike njikọ dị n'elu ala na tile.
2. Mgbanwe nke ukwuu na Rheology: Cellulose ethers na-eje ozi dị ka ndị na-eme ihe na-eme ka ihe na-eme ka ọkpụkpụ na ndị na-emegharị ihe na-eme ka ihe na-edozi taịlị, na-enye viscosity, nkwụsi ike, na nguzogide sag na nrapado. Ha na-enyere aka igbochi ịlanarị ma ọ bụ slumping nke nrapado n'oge ngwa kwụ ọtọ, na-ahụ maka mkpuchi otu na akwa akwa akwa na mgbidi na elu ụlọ.
3. Nkwado emelitere: Cellulose ethers na-eme ka adhesion na ike njikọ nke tile adhesives na ihe dị iche iche dị iche iche, gụnyere ihe, masonry, gypsum board, na plywood. Site n'ịkwalite mmekọrịta chiri anya n'etiti nrapado na ihe ndị dị n'elu, cellulose ethers na-eme ka adhesion na-ebelata ihe ize ndụ nke delamination tile ma ọ bụ debonding ka oge na-aga.
4. Mbelata na mgbawa na mgbawa: Cellulose ethers na-enyere aka belata mbelata na mgbawa na usoro nrapado taịlị site na imezi njikọ, mgbanwe, na nkesa nrụgide n'ime matrix adhesive. Ha na-ebelata mmetụta nke ihicha shrinkage na mgbasawanye ọkụ, na-eme ka ịdịte aka ogologo oge na arụmọrụ nke elu tiled, karịsịa na nrụgide dị elu ma ọ bụ ọnọdụ okpomọkụ.
5. Enwetara arụmọrụ na mgbasawanye: Cellulose ethers na-eme ka arụ ọrụ na mgbasawanye nke tile adhesives, na-eme ka ọ dị mfe ngwa na troweling. Ha na-eme ka ngwa dị nro, na-agbanwe agbanwe nke nrapado n'elu nnukwu ebe dị elu, na-enye ohere maka ntinye nke taịl nile nke ọma na obere mgbalị na mkpofu.
6. Oge nhazi oge na-agbanwe agbanwe: Cellulose ethers na-enye njikwa n'oge nhazi oge nke adhesives tile, na-enye ohere maka mgbanwe iji kwekọọ ngwa ngwa chọrọ na ọnọdụ saịtị. Site n'ịgbanwe usoro onunu ogwu ma ọ bụ ụdị cellulose ether eji, ndị ọrụ nkwekọrịta nwere ike ịhazi oge nhazi nke nrapado iji nabata usoro iheomume na mgbanwe okpomọkụ.
7. Ndakọrịta na ihe mgbakwunye: Cellulose ethers na-egosipụta ezigbo ndakọrịta na mgbakwunye dị iche iche a na-ejikarị eme ihe n'ụdị nrapado tile, gụnyere ndị na-agbanwe latex, ikuku entrainers, na ndị na-egbochi sag. Enwere ike itinye ha n'ụzọ dị mfe n'ime usoro nrapado iji kwalite arụmọrụ yana lebara ihe ịma aka ngwa ngwa anya, dị ka ngbanwe mgbanwe, nguzogide mmiri ka mma, ma ọ bụ nkwalite nrapanye na ihe ndị na-adịghị agba.

cellulose ethers na-arụ ọrụ dị mkpa n'ụdị nrapado tile, na-atụnye aka n'ịrụ ọrụ nke ọma, nrapado, ịdịte aka, na ịrụ ọrụ nke elu tiled. Ntugharị ha, ịdị irè, na ndakọrịta na mgbakwunye ndị ọzọ na-eme ka ha bụrụ akụkụ bara uru na mmepe nke nrapado taịlị dị elu maka ma azụmahịa ma ọrụ owuwu ụlọ.
