Kedu ka esi ejikwa nke ọma na arụ ọrụ cellulose ethers na ngwaahịa ciment?

Cellulose ethers, dị ka methyl cellulose (MC) na hydroxypropyl methyl cellulose (HPMC), na-ọtụtụ ebe na-eji ciment dabeere ngwaahịa n'ihi na ha magburu onwe mmiri njide, workability, na adhesion Njirimara. Otú ọ dị, arụmọrụ nke cellulose ethers na ngwaahịa ciment nwere ike imetụta ihe dị iche iche, gụnyere ụdị na usoro nke cellulose ether, ụdị na usoro nke ciment, ọnọdụ ọgwụgwọ, na ọnọdụ gburugburu ebe obibi. Ya mere, ọ dị mkpa ijikwa ọrụ nke cellulose ethers nke ọma na ngwaahịa ciment iji hụ na ịdị mma na arụmọrụ na-agbanwe agbanwe.

  1. Nhọrọ nke Cellulose Ether Ụdị na usoro onunu ogwu

Nhọrọ nke cellulose ether ụdị na usoro onunu ogwu dị oke mkpa n'ịchịkwa ọrụ nke cellulose ethers na ngwaahịa ciment. Eter cellulose dị iche iche nwere ihe dị iche iche, na nhọrọ nke ụdị cellulose ether kwesịrị ekwesị na-adabere na ngwa ngwa na arụmọrụ chọrọ. Dịka ọmụmaatụ, a na-ejikarị HPMC eme ihe na nkedo adhesives n'ihi njide mmiri dị mma na ihe nkpuchi, ebe a na-ejikarị MC eme ihe na nsụgharị na ngwa agha n'ihi ọrụ ya dị mma na njide mmiri.

Usoro onunu ogwu nke cellulose ether na-ekerekwa òkè dị ukwuu n'ịchịkwa ọrụ ya na ngwaahịa ciment. Usoro kwesịrị ekwesị nke cellulose ether na-adabere n'ihe dị iche iche, gụnyere ụdị na usoro nke ciment, ọrụ a chọrọ na njide mmiri, na ọnọdụ gburugburu ebe obibi. N'ozuzu, usoro onunu ogwu nke cellulose ether sitere na 0.1% ruo 2% site n'ịdị arọ nke ciment, dabere na ngwa ngwa na arụmọrụ chọrọ.

  1. Ndakọrịta na ciment

Nkwekọrịta nke cellulose ether na ciment dị oké mkpa n'ịchịkwa ọrụ ya na ngwaahịa ciment. Mgbakwunye nke cellulose ether na ciment nwere ike imetụta nhazi oge, ike, na ịrụ ọrụ nke ciment, dabere na ụdị na usoro nke cellulose ether na ụdị ciment. Ya mere, ọ dị mkpa iji hụ na ndakọrịta nke cellulose ether na ciment iji hụ na ịdị mma na arụmọrụ na-agbanwe agbanwe.

Enwere ike ịtụle ndakọrịta nke cellulose ether na ciment site na ịme ule ndakọrịta, dị ka ule Vicat, ule mmalite na nke ikpeazụ na oge nhazi oge, na ule mkpakọ. Nsonaazụ nke ule ndị a nwere ike inye ozi bara uru na arụmọrụ cellulose ether na ngwaahịa ciment ma nwee ike iji mee ka ụdị na usoro nke cellulose ether dị elu.

  1. Ọnọdụ ọgwụgwọ

Ọnọdụ ọgwụgwọ nke ngwaahịa ciment nwere ike imetụta arụmọrụ cellulose ethers. Ọnọdụ ọgwụgwọ, gụnyere okpomọkụ, iru mmiri, na oge ọgwụgwọ, nwere ike imetụta hydration nke ciment na arụmọrụ nke ethers cellulose. Ọnọdụ ọgwụgwọ kachasị mma dabere na ngwa a kapịrị ọnụ yana ihe achọrọ.

Dịka ọmụmaatụ, na nrapado tile, ọnọdụ ọgwụgwọ kachasị mma na-abụkarị na ụlọ okpomọkụ na oke iru mmiri yana oge ọgwụgwọ nke awa 24 ruo 48. Na nsụgharị na ngwa agha, ọnọdụ ọgwụgwọ kachasị mma nwere ike ịdịgasị iche dabere na ngwa a kapịrị ọnụ, mana na-agụnyekarị okpomọkụ dị elu yana ogologo oge ọgwụgwọ.

  1. Ọnọdụ gburugburu

Ọnọdụ gburugburu ebe obibi, dị ka okpomọkụ, iru mmiri, na ikpughe na kemịkalụ ma ọ bụ ihe mmetọ, nwekwara ike imetụta ọrụ ethers cellulose na ngwaahịa ciment. Dịka ọmụmaatụ, ikpughe na okpomọkụ dị elu ma ọ bụ iru mmiri dị ala nwere ike imetụta njigide mmiri nke ethers cellulose, na-eduga n'ibelata ọrụ na nrapado. Ngosipụta na kemịkalụ ma ọ bụ ihe mmetọ nwekwara ike imetụta arụmọrụ cellulose ethers, na-eduga n'ibelata ike ma ọ bụ ogologo oge.

Ya mere, ọ dị mkpa ịtụle ọnọdụ gburugburu ebe obibi n'oge ntinye na iji cellulose ethers na ngwaahịa ciment. Nchekwa nke ọma na njikwa cellulose ethers nwekwara ike inye aka ịnọgide na-arụ ọrụ ha ma hụ na ịdị mma na-agbanwe agbanwe.

N'ikpeazụ, njikwa dị irè nke ọrụ cellulose ethers na ngwaahịa ciment chọrọ nlezianya tụlee ihe dị iche iche, gụnyere ụdị na usoro nke cellulose ether, ndakọrịta na ciment, ọnọdụ ọgwụgwọ, na ọnọdụ gburugburu ebe obibi. Site n'ịkwalite ihe ndị a, ọ ga-ekwe omume ịmepụta àgwà na-agbanwe agbanwe na arụmọrụ nke cellulose ethers na ngwaahịa ciment, na-eduga n'ịrụ ọrụ nke ọma, njide mmiri, na njigide.

Iji chịkwaa nke ọma arụmọrụ cellulose ethers na ngwaahịa ciment, ọ dịkwa mkpa iji cellulose ethers dị elu sitere na ndị na-ebubata ngwaahịa a ma ama. Ethers cellulose dị elu nwere akụrụngwa na arụmọrụ na-agbanwe agbanwe, na-enye ohere maka dosing ziri ezi na njikwa ka mma na arụmọrụ ngwaahịa ikpeazụ.

Ịgbaso ntuziaka ndị a nwere ike inye aka hụ na arụmọrụ kachasị mma nke cellulose ethers na ngwaahịa ciment.

N'ozuzu, njikwa dị irè nke ọrụ cellulose ethers na ngwaahịa ciment na-achọ ịghọta nke ọma ihe ndị na-emetụta arụmọrụ ha na iji nlezianya tụlee ihe ndị a n'oge mmepụta ngwaahịa, mmepụta ihe, na ngwa ngwa. Site n'ịkwalite ihe ndị a na iji cellulose ethers dị elu, ọ ga-ekwe omume ịmepụta àgwà na-arụ ọrụ nke cellulose ethers na ngwaahịa ciment, na-eduga n'ịrụ ọrụ nke ọma, njide mmiri, na ihe nkwụnye.
