Methylhydroxyethylcellulose (MHEC) bụ ether cellulose dị iche iche nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche n'ihi njigide mmiri ya dị mma na ihe nrapado.MHEC sitere na cellulose eke wee chọta ngwa na ihe owuwu, ọgwụ, nri na ihe ịchọ mma.
Usoro na Njirimara:
MHEC bụ ihe amịpụtara hydroxyethylcellulose nke nọchiri anya methyl nwere usoro mkpụrụ ndụ pụrụ iche.Ọkpụkpụ azụ cellulose na-enye biodegradability dị omimi na ndakọrịta gburugburu ebe obibi, na-eme MHEC nhọrọ mbụ maka ọtụtụ ngwa.Hydroxyethyl na methyl dị iche iche na-eme ka solubility ya dịkwuo mma ma gbanwee ọdịdị anụ ahụ na kemịkal ya, na-enye ya ọrụ dịgasị iche iche.
Usoro njide mmiri:
Otu n'ime àgwà ndị bụ isi nke MHEC bụ ikike njigide mmiri ya dị mma.N'ime ihe owuwu dị ka ngwa agha na ngwaahịa ciment, MHEC na-arụ ọrụ dị ka onye na-ejide mmiri, na-egbochi mmiri ngwa ngwa n'oge usoro ọgwụgwọ.Nke a dị mkpa iji nọgide na-enwe usoro nhazi kachasị mma, melite adhesion na ịkwalite arụmọrụ zuru oke nke ihe ahụ.
MHEC na-enweta njide mmiri site n'ọtụtụ usoro:
Hydrophilicity: Ọdịdị hydrophilic nke MHEC na-enyere ya aka ịmịkọrọ ma na-ejigide ụmụ irighiri mmiri.Ọkpụkpụ azụ cellulose, yana otu hydroxyethyl na methyl, na-etolite nhazi nke nwere ike idowe mmiri n'ime matriks ya.
Ihe na-emepụta ihe nkiri: MHEC nwere ike ịmepụta ihe nkiri dị gịrịgịrị, na-agbanwe agbanwe mgbe a gbasasịrị na mmiri.Ihe nkiri a na-eme dị ka ihe mgbochi, na-ebelata evaporation nke mmiri ma na-enye mkpuchi nchebe iji nọgide na-enwe mmiri n'ime ihe.
Mmetụta siri ike: Ebe ọ bụ na MHEC na-aza na mmiri, ọ na-egosipụta mmetụta na-eme ka ọkpụkpụ.Nke a na-abawanye viscosity na-enye aka na njigide mmiri dị mma, na-egbochi mmiri ikewapụ na ihe onwunwe na ịnọgide na-enwe ngwakọta nke otu.
Ngwa na-ewu:
Ụlọ ọrụ na-ewu ụlọ na-adabere na MHEC maka ihe eji ejide mmiri.MHEC na-erite uru ngwa agha, grout na ihe simenti ndị ọzọ site n'ịkwalite ịrụ ọrụ, ibelata mgbawa na imeziwanye nrapado.Na mgbakwunye, MHEC na-eme ka mgbapụta na ịgbasa ihe eji arụ ụlọ, na-eme ka ọ bụrụ ihe mgbakwunye bara uru na usoro ihe owuwu ọgbara ọhụrụ.
Njirimara nrapado:
Na mgbakwunye na njide mmiri, MHEC na-arụ ọrụ dị mkpa iji meziwanye adhesion na ngwa dị iche iche.Njirimara nrapado ya bara uru karịsịa na ụlọ ọrụ ndị a:
Adhesives Tile: A na-ejikarị MHEC eme ihe na nrapado tile iji kwalite ike njikọ dị n'etiti taịlị na mkpụrụ.Ọ na-emepụta ihe nkiri na-agbanwe agbanwe ma na-eme ka arụ ọrụ dịkwuo mma, na-eme ka njikọ siri ike na ogologo oge.
Pasting akwụkwọ ahụaja: N'ime mmepụta akwụkwọ ahụaja, MHEC na-enyere aka ijikọ akwụkwọ ahụaja na mgbidi.Ọ na-egbochi mado ahụ ka ọ ghara ịnwụ n'oge na-adịghị anya ma na-akwalite njikọ siri ike ma na-adịte aka.
Ngwakọta nkwonkwo: A na-eji MHEC eme ihe na nkwonkwo n'ihi njide ya na ihe na-eme ka ọ dị arọ.Ọ na-enyere aka nweta mmecha nke ọma na nrapado na ngwa drywall.
na ngwụcha:
Methylhydroxyethylcellulose (MHEC) bụ cellulose ether nwere ihu nwere ezigbo njide mmiri na ihe nrapado.Ọdịdị molekụla ya pụrụ iche, hydrophilicity, ikike imepụta ihe nkiri na mmetụta na-eme ka ọ bụrụ nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche.Site na ihe owuwu ụlọ ruo na ọgwụ na ihe ịchọ mma, MHEC na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ ngwaahịa na ịhụ na arụmọrụ kacha mma.Ka ụlọ ọrụ na-aga n'ihu na-achọ ihe ngwọta dị mma na gburugburu ebe obibi na nke dị irè, MHEC na-anọgide na-abụ nhọrọ bara uru na nke na-adịgide adịgide maka ngwa dị iche iche.
