Focus on Cellulose ethers

Kedu ihe kpatara ụda ngwa agha ji abawanye mgbe ị gbakwunyere cellulose ether?

1. Okwu mmalite nke cellulose ether:

Ọdịdị kemịkalụ: Cellulose ethers bụ polymers soluble mmiri na-enweta site na cellulose, a eke polysaccharide dị na osisi mgbidi cell. Ọ mejupụtara nkeji glucose ugboro ugboro jikọtara ya na njikọ β-1,4-glycosidic.

Hydrophilicity: Cellulose ether bụ hydrophilic, nke pụtara na ọ nwere njikọ siri ike maka mmiri.

2. Ọrụ cellulose ether na ngwa agha:

Njide mmiri: Otu n'ime isi ọrụ cellulose ether na ngwa agha bụ ịkwalite njide mmiri. Ọ na-emepụta ihe nkiri dị mkpa gburugburu akụkụ ciment, na-ebelata evaporation nke mmiri na-eme ka usoro hydration dịkwuo ogologo.

Meziwanye ikike ịrụ ọrụ: Cellulose ether na-arụ ọrụ dị ka ihe ngbanwe rheology iji meziwanye ikike ngwa agha. Nke a dị mkpa karịsịa maka ngwa ndị dị ka plasta na nsụgharị.

3. Mmetụta na ụda ngwa agha:

Mmiri Absorption: Ọdịdị hydrophilic nke cellulose ethers na-enyere ha aka ịmịnye mmiri site na ngwakọta. Ka ọ na-agbasawanye, mkpokọta mmiri dị na ngwa ngwa na-abawanye, na-eme ka mmụba olu.

Ntinye ikuku: Ịgbakwunye cellulose ethers nwere ike iwebata ikuku n'ime ngwa agha ahụ. Afụ ikuku tọrọ atọ na-enye aka n'uru olu.

Ọdịdị nke pore: Cellulose ethers nwere ike imetụta microstructure nke ngwa agha ahụ, na-eme ka netwọk dịkwuo njọ. Mgbanwe a na nhazi pore na-ebute mmụba dị ukwuu na olu.

4.Hydration usoro na mmụba olu:

Mmiri mmiri na-egbu oge: Cellulose ethers nwere ike belata usoro hydration nke ciment. Mmiri mmiri a na-egbu oge na-enye ohere ka ikesa mmiri dị n'ime ngwa ngwa, nke nwere ike ime ka mmụba dị elu.

Mmetụta na-agwọ ọrịa: Mgbakwunye mmiri na-agbatị nke cellulose ethers na-akwalite na-enyere aka ịgbatị oge ọgwụgwọ, na-ekwe ka irighiri ciment na-eme ka mmiri dị ọcha kpamkpam ma na-emetụta ụda ikpeazụ nke ngwa agha ahụ.

5. Mmekọrịta na ihe ndị ọzọ:

Mmekọrịta ihe nkedo: Cellulose ethers na-emekọ ihe na-ejikọta ciment iji mepụta matriks kwụsiri ike. Mmekọrịta a na-emetụta nhazi nke ihe ndị ahụ ma na-eduga na mgbasawanye olu.

Njikọ mmekọrịta: Ọ bụrụ na a na-eji cellulose ethers na ihe mgbakwunye ndị ọzọ, mmetụta synergistic nwere ike ime, na-emetụta ọnụ ọgụgụ nke ngwa agha.

6. Mgbasa na nkesa urughuru:

Mgbasa n'ụdị: Mgbe cellulose ether na-agbasasị nke ọma n'ime ngwa agha ahụ, ọ nwere ike ime ka nkesa ahụ dịkwuo otu. Otu n'otu a na-emetụta njupụta nkwakọ ngwaahịa ma si otú a na-emetụta ụda ngwa ngwa.

7. Ọnọdụ gburugburu:

Okpomọkụ na iru mmiri: Ọnọdụ gburugburu ebe obibi dị ka okpomọkụ na iru mmiri nwere ike imetụta omume cellulose ethers na ngwa agha. Ọzịza na ntinye mmiri nwere ike ịdị iche iche n'okpuru ọnọdụ gburugburu ebe obibi dị iche iche, na-emetụta olu.

8. Nkwubi okwu:

Na nchịkọta, mmụba olu a na-ahụ na mgbakwunye nke cellulose ethers na ngwa agha bụ ihe si na mmekọrịta dị mgbagwoju anya gụnyere iweta mmiri, hydration na-egbu oge, ntinye ikuku, na mgbanwe na microstructure ngwa agha. Ịghọta usoro ndị a dị oke mkpa iji kwalite iji cellulose ethers na ngwakọta ngwa agha wee nweta ihe ndị a chọrọ na ngwa ụlọ.
