Cellulose ethers Nkwalite arụmọrụ maka ma drymix ngwa agha na eserese

Cellulose ethers bụ ihe mgbakwunye dị iche iche na-enye nkwalite arụmọrụ dị ịrịba ama maka ngwa ngwa drymix na eserese. Ka anyị nyochaa ka ihe mgbakwunye ndị a na-enye aka n'ịkwalite njirimara na ọrụ nke ọ bụla:

1. Drymix Mortars: Drymix Mortars bụ ngwakọta nke simenti, ájá na ihe mgbakwunye ndị a na-eji eme ihe n'ime ngwa owuwu dịka tile adhesives, grouts, renders na plasta. Cellulose ethers na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke ngwa agha drymix n'ụzọ ndị a:
   • Njide mmiri: Cellulose ethers, dị ka Hydroxyethyl Methyl Cellulose (HEMC) na Hydroxypropyl Methyl Cellulose (HPMC), nwere ezigbo njide mmiri. Ha na-etolite ihe nkiri nchebe gburugburu akụkụ ciment, na-ebelata evaporation nke mmiri n'oge ọgwụgwọ. Nke a na-eme ka arụ ọrụ dịkwuo mma, na-agbatị oge oghe, ma na-eme ka adhesion dịkwuo elu, na-ebelata ihe ize ndụ nke nkwụsịtụ na-eme ka mmiri dị mma nke ihe cimenti.
   • Ọkpụkpụ na njikwa Rheology: Cellulose ethers na-arụ ọrụ dị ka ndị na-eme ihe na-eme ka ndị na-eme ihe na-eme ka ọkpụkpụ na-eme ka ọkpụkpụ na-eme ka ọkpụkpụ na-eme ka ọkpụkpụ na-eme ka ọ dịkwuo mma, na-eme ka nkwụsi ike, na-asọpụta, na nguzogide sag. Ha na-eme omume na-akpụ akpụ, na-eme ka ngwa agha dị mfe itinye ma na-egbochi mkpọda n'oge ngwa kwụ ọtọ. A na-ejikarị Ethyl Hydroxyethyl Cellulose (EHEC) na Carboxymethyl Cellulose (CMC) eme ihe maka ihe na-eme ka ha sie ike na njikwa rheological.
   • Adhesion na Cohesion: Cellulose ethers na-eme ka adhesion na njikọ nke drymix Mortars site na ịmepụta ihe nkiri na-agbanwe agbanwe, nke na-ejikọta nke ọma na ihe dị iche iche. Nke a na-eme ka ike nkekọ dịkwuo mma, na-ebelata ihe ize ndụ nke debonding ma ọ bụ delamination, ma na-akwalite ịdịte aka n'ozuzu nke ngwa agha ahụ.
   • Mgbochi mgbawa na ịdịte aka: Mgbakwunye nke cellulose ethers na-eme ka nkwụsị mgbawa na ịdịte aka nke drymix Mortars site na ibelata mbelata, ịchịkwa hydration, na ịkwalite njikọ nke ngwa ngwa ngwa. Nke a na-ebute ihe owuwu siri ike ma na-adịte aka, nke nwere ike iguzogide nrụgide gburugburu ebe obibi na mmegharị nhazi.
2. Agba: Agba bụ usoro dị mgbagwoju anya nke nwere pigmenti, ihe nkedo, ihe mgbaze na ihe mgbakwunye. Cellulose ethers na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke agba mmiri na ụzọ ndị a:
   • Njikwa viscosity: Cellulose ethers na-arụ ọrụ dị ka ndị na-arụ ọrụ nke ọma na agba nke mmiri, na-achịkwa viscosity ma na-egbochi nkwụsị ma ọ bụ ntapu n'oge ngwa. Nke a na-eme ka mkpuchi nke otu dị n'otu, nwelite brushability, na emelitere ihe nkiri na-ewuli elu n'elu kwụ ọtọ. Hydroxyethyl Cellulose (HEC) na Hydroxypropyl Methyl Cellulose (HPMC) ka a na-ejikarị maka njikwa viscosity na eserese.
   • Nkwụsi ike na nkwusioru: Cellulose ethers na-enye aka na nkwụsi ike nke pigmenti na ndị na-ejuputa n'ụdị agba, na-egbochi nhazi na ịhụ mgbasa nke otu. Nke a na-eme ka agba agba agba, na-ebelata sedimentation, na-eme ka ndụ ndụ nke agba ahụ dịkwuo mma.
   • Ntughari na ọkwa: Mgbakwunye nke cellulose ethers na-eme ka mmiri na-asọpụta na nhazi ọkwa nke agba ndị dabeere na mmiri, na-eme ka ọ dị nro, na-emecha ya na obere akara nchara ma ọ bụ ihe nrịbama. Nke a na-eme ka mma mma nke ọrụ agba na-ebelata mkpa maka nkwadebe elu.
   • Nhazi ihe nkiri na ịdịte aka: Cellulose ethers na-enye aka n'ịmepụta ihe nkiri na-aga n'ihu, na-ejikọta ọnụ na mkpụrụ, na-eme ka adhesion dịkwuo mma, nkwụsị nke abrasion, na ihu igwe nke agba. Nke a na-eme ka ịdịte aka na ịrụ ọrụ ogologo oge nke elu a na-ese, ọbụna n'okpuru ọnọdụ gburugburu ebe obibi siri ike.

N'ikpeazụ, cellulose ethers na-enye nkwalite arụmọrụ dị ịrịba ama maka ma drymix mortars na paints site na imezi njide mmiri, njupụta, njikwa rheology, adhesion, cohesion, crack resistance, and inteability. Ntugharị ha na ịdị irè ha na-eme ka ha bụrụ ihe mgbakwunye dị mkpa na-ewu na mkpuchi ngwa, na-enye aka na mmepụta nke ihe ndị dị elu, ndị na-adịgide adịgide, na ndị mara mma.
