Methyl Hydroxyethyl Cellulose (MHEC) bụ thickener na nrapado a na-ejikarị eme ihe ụlọ. Okwu mmeghe ya nwere mmetụta dị ukwuu na njirimara nke matrix ciment.
1. Melite fluidity na workability
Methyl hydroxyethyl cellulose, dị ka a thickener, nwere ike imeziwanye fluidity nke ciment matriks. Ọ na-eme ka ciment slurry kwụsie ike na mmiri n'oge usoro ihe owuwu site na ịbawanye viscosity nke ngwakọta. Nke a na-enyere aka mejupụta ihe dị mgbagwoju anya ma belata spatter n'oge a na-ewu ụlọ. Na mgbakwunye, methyl hydroxyethyl cellulose nwekwara ike ịkwalite njide mmiri nke matriks ciment ma belata ihe na-agba ọbara nke simenti slurry, si otú ahụ na-eme ka mma ụlọ dị mma.
2. Meziwanye adhesion
Methyl hydroxyethyl cellulose nwere ike imeziwanye njirimara njikọ nke matriks ciment. Nke a bụ n'ihi na ọ nwere ihe nrapado dị mma ma nwee ike ijikọta ya na mmiri dị na ciment iji mepụta colloid na nrapado siri ike. Mmetụta mgbanwe a dị ezigbo mkpa maka imeziwanye njikọ dị n'etiti cement matrix na mkpụrụ, karịsịa na plasta mgbidi, ihe nkedo seramiiki na ngwa ndị ọzọ.
3. Na-emetụta ike na ogologo oge
Mgbakwunye methylhydroxyethylcellulose nwere mmetụta ụfọdụ na ike nke matriks ciment. N'ime usoro ọgwụgwọ ụfọdụ, methylhydroxyethyl cellulose nwere ike melite ike mkpakọ na ike mgbanwe nke matriks ciment. Site n'ịkwalite ịdị n'otu na nkwụsi ike nke tapawa ciment, ọ na-ebelata pores na mgbawa na matrix ciment, si otú ahụ na-eme ka ike zuru ezu na ịdịte aka nke ihe. Otú ọ dị, ọ bụrụ na agbakwunyere nke ukwuu, ọ nwere ike ime ka mbelata nkekọ dị n'etiti ciment na nchịkọta na matrix ciment, si otú ahụ na-emetụta ike ya.
4. Meziwanye nkwụsị mgbape nke matrix ciment
Ebe ọ bụ na methylhydroxyethylcellulose nwere ike imezi njigide mmiri nke matriks ciment, ọ nwere ike ibelata mgbawa na-akpata site na ihicha ruo n'ókè ụfọdụ. Ịkpọ nkụ nke cement matrix bụ otu n'ime isi ihe na-akpata mgbawa, na methylhydroxyethyl cellulose na-enyere aka belata ihe ize ndụ nke cracks kpatara site na ihicha shrinkage site n'ibelata evaporation nke mmiri ngwa ngwa.
5. Afụ akara na ciment matrix
Methyl hydroxyethyl cellulose nwere ike ịmepụta usoro ụfụfụ kwụsiri ike na matriks ciment, nke na-enyere aka melite mkpuchi ikuku nke matrix ciment. Ihe njikwa ikuku ikuku a na-ekere òkè n'ịkwalite njirimara mkpuchi ọkụ nke matriks ciment na ibelata njupụta nke matriks ciment. Otú ọ dị, ọtụtụ afụ nwere ike ime ka ihe ahụ ghara ịdị ike, ya mere, ọ dị mkpa ka a gbakwunye ego kwesịrị ekwesị dabere na ngwa a kapịrị ọnụ.
6. Melite impermeability
Site n'ịkwalite njide mmiri nke matriks ciment, methylhydroxyethylcellulose nwere ike ibelata permeability nke matriks ciment. Nke a dị ezigbo mkpa iji melite impermeability na waterproof arụmọrụ nke cement matrix, karịsịa na ngwa na-achọ waterproofing, dị ka okpuru ulo, mpụta mgbidi, wdg.
Ngwa nke methylhydroxyethyl cellulose na cement matriks nwere ike iweta nkwalite arụmọrụ dị iche iche, gụnyere ime ka mmiri dị mma, ime ka adhesion dịkwuo elu, na-eme ka ike dịkwuo elu, na-eme ka nkwụsị mgbawa dịkwuo elu, na-achịkwa afụ na ime ka ọ dịkwuo mma. Agbanyeghị, ojiji ya na oke ya kwesịrị ka edozi ya nke ọma dabere na mkpa ngwa akọwapụtara yana ihe achọrọ iji nweta nsonaazụ kacha mma. Site na mgbakwunye sayensị na ezi uche na nkwadebe, methyl hydroxyethyl cellulose nwere ike imeziwanye arụmọrụ nke matrix ciment nke ọma ma gboo mkpa injinia dị iche iche.
