Ihe na-emetụta cellulose ether na ciment Mortar

Cellulose ethers na-ekere òkè dị ukwuu n'ịmetụta njirimara nke ngwa ngwa ciment, na-emetụta ọrụ ya, nrapanye, njide mmiri, na ike ọrụ. Ọtụtụ ihe nwere ike imetụta arụmọrụ cellulose ethers na ngwa ngwa ciment:

  1. Ngwakọta kemịkalụ: Ngwakọta kemịkalụ nke cellulose ethers, gụnyere ogo nnọchi (DS) na ụdị nke otu na-arụ ọrụ (dịka ọmụmaatụ, methyl, ethyl, hydroxypropyl), na-emetụta omume ha na ngwa ngwa ciment. DS dị elu na ụfọdụ ụdị ọrụ na-arụ ọrụ nwere ike ịkwalite njide mmiri, nrapanye, na ihe na-eme ka ọ dị elu.
  2. Oke urughuru na nkesa: The urughuru size na nkesa nke cellulose ethers nwere ike imetụta ha dispersibility na mmekọrịta na ciment ahụ. Ihe ndị dị mma nwere nkesa otu na-agbasawanye nke ọma na matriks ngwa ngwa, na-eduga na njigide mmiri dị mma na ịrụ ọrụ.
  3. Usoro onunu ogwu: Usoro nke cellulose ethers na ciment mortar formulations na-emetụta ọrụ ha ozugbo. A na-ekpebi usoro onunu kacha mma dabere na ihe ndị dị ka ike ịrụ ọrụ nke chọrọ, ihe ndị chọrọ ijide mmiri, na ike igwe. Usoro onunu ogwu gabigara oke nwere ike iduga nbibi oke ma obu nbilata nke ịtọ oge.
  4. Usoro ịgwakọta: Usoro ngwakọta, gụnyere oge ịgwakọta oge, ịgbakọta ọsọ, na usoro ntinye nke ihe mgbakwunye, nwere ike imetụta mgbasa na hydration nke cellulose ethers na ngwa ngwa ciment. Ịgwakọta nke ọma na-eme ka a hụ nkesa nke cellulose ethers n'otu n'otu n'ime matriks ngwa agha, na-eme ka arụmọrụ ha dịkwuo mma n'ịkwalite ọrụ na nrapado.
  5. Ihe mejupụtara ciment: Ụdị na ngwakọta nke ciment eji eme ihe na ngwa ngwa nwere ike imetụta ndakọrịta na arụmọrụ nke cellulose ethers. Ụdị simenti dị iche iche (dịka, simenti Portland, ciment agwakọta) nwere ike igosi mmekọrịta dị iche iche na cellulose ethers, na-emetụta ihe ndị dị ka ịtọ oge, mmepe ike, na ịdịte aka.
  6. Ngwakọta mkpokọta: Njirimara nke mkpokọta (dịka ọmụmaatụ, nha nha, ọdịdị, udidi elu) nwere ike imetụta arụmọrụ cellulose ethers na ngwa agha. Mkpokọta nwere elu siri ike ma ọ bụ ọdịdị na-adịghị agbanwe agbanwe nwere ike inye njikọ dị mma na cellulose ethers, na-eme ka nrapanye na njikọta na ngwa agha dịkwuo mma.
  7. Ọnọdụ gburugburu ebe obibi: Ihe ndị dị na gburugburu ebe obibi dị ka okpomọkụ, iru mmiri, na ọnọdụ ọgwụgwọ nwere ike imetụta hydration na arụmọrụ nke cellulose ethers na simenti ngwa ngwa. Oke okpomoku ma ọ bụ oke iru mmiri nwere ike ịgbanwe oge nhazi, ịrụ ọrụ, na akụrụngwa ngwa ngwa nwere ethers cellulose.
  8. Mgbakwunye ihe mgbakwunye ndị ọzọ: Ọnụnọ nke ihe mgbakwunye ndị ọzọ, dị ka superplasticizers, ndị na-eme ka ikuku ikuku, ma ọ bụ ndị na-eme ngwa ngwa, nwere ike ịmekọrịta na cellulose ethers ma na-emetụta arụmọrụ ha na ciment mortar. Ekwesịrị ịme nnwale ndakọrịta iji chọpụta mmetụta synergistic ma ọ bụ mmegide nke ijikọ cellulose ethers na mgbakwunye ndị ọzọ.

ịghọta ihe ndị na-emetụta cellulose ethers na ngwa ngwa ciment dị oké mkpa maka ịkwalite usoro ngwa ngwa yana nweta ihe ndị a chọrọ dị ka ịrụ ọrụ nke ọma, njide mmiri, na ike ọrụ. Ime nyocha na nnwale nke ọma nwere ike inye aka chọpụta ngwaahịa ether cellulose kacha dabara adaba na ọkwa usoro onunu maka ngwa ngwa ngwa akọwapụtara.
