A na-eji cellulose ethers, karịsịa Methyl Hydroxyethyl Cellulose (MHEC), n'ọtụtụ ebe n'ime ụlọ ọrụ dị iche iche maka ihe onwunwe ha dị ịrịba ama. MHEC bụ ihe nrụpụta cellulose gbanwetụrụ nke na-eme ka arụ ọrụ nke nrapado na mkpuchi dị elu. Ngwakọta a na-enye ọtụtụ uru, gụnyere mma viscosity, njide mmiri, ịrụ ọrụ, na nkwụsi ike. Ịghọta usoro a kapịrị ọnụ nke MHEC na-eme ka adhesives na sealants nwere ike inye nghọta bara uru na ngwa ya na uru ya na ụlọ ọrụ ndị a.
Mma viscosity na Rheology
Otu n'ime ụzọ bụ isi MHEC na-eme ka arụmọrụ nke adhesives na sealants dịkwuo mma bụ site na mmetụta ya na viscosity na rheology. MHEC ụmụ irighiri ihe, mgbe agbazere na mmiri, na-etolite ngwọta viscous nke ukwuu. Nke a na-abawanye viscosity dị oké mkpa maka adhesives na sealants ka ọ na-eme ka a na-achịkwa ngwa ngwa, na-ebelata ọchịchọ nke ngwaahịa na-agba ọsọ ma ọ bụ sag. Ngwongwo a bara uru karịsịa maka ngwa kwụ ọtọ ebe idobe ọnọdụ nke nrapado ma ọ bụ akara dị oke mkpa.
Omume rheological nke MHEC na-enye na-enyere aka n'inweta ọdịdị thixotropic na nrapado na mkpuchi. Thixotropy na-ezo aka na ihe onwunwe nke ụfọdụ gels ma ọ bụ mmiri mmiri dị oke (viscous) n'okpuru ọnọdụ dị iche iche ma na-asọpụta (na-aghọ obere viscous) mgbe iwe iwe ma ọ bụ nrụgide. Nke a pụtara na adhesives na sealants nwere MHEC nwere ike itinye ngwa ngwa mgbe etinyere shii (dịka ọmụmaatụ, n'oge ịchacha ma ọ bụ troweling) mana nwetaghachi viscosity ha ngwa ngwa ozugbo ewepụrụ ike ngwa ahụ.

A maara MHEC maka ikike ijide mmiri dị mma. N'ihe gbasara adhesives na sealants, ihe onwunwe a bara uru karịsịa. Njide mmiri dị oke mkpa n'ịhụ na ọgwụgwọ na ịtọọ ihe ndị a nke ọma. Mmiri zuru oke dị mkpa maka usoro hydration na ciment nke dabeere na ciment, na n'ụdị ndị ọzọ, ọ na-eme ka nrapado na-anọgide na-arụ ọrụ ruo ogologo oge tupu ịtọ ntọala.
Ngwongwo njide mmiri nke MHEC na-enyere aka idowe steeti hydration nke nrapado ma ọ bụ akara, nke dị oke mkpa maka inweta ike njikọ kacha. Na adhesives dabeere na ciment, MHEC na-egbochi ihicha oge, nke nwere ike iduga hydration na-ezughị ezu na ike belata.
