Methylhydroxyethylcellulose (MHEC) bụ cellulose ether nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ụlọ na ihe owuwu. N'ime ihe mkpuchi ụlọ, MHEC bụ ihe dị mkpa dị mkpa nke na-enye ihe ndị a kapịrị ọnụ na mkpuchi ahụ, si otú a na-eme ka arụmọrụ ya dịkwuo elu.
Okwu Mmalite nke Methyl Hydroxyethyl Cellulose (MHEC)
MHEC bụ cellulose ether na-abụghị ionic enwetara site na polymer cellulose eke sitere na usoro mgbanwe kemịkalụ. Eji nchikota pụrụ iche nke methyl na otu hydroxyethyl mara ya na ọkpụkpụ azụ cellulose ya. Usoro ihe omimi a na-enye MHEC ezigbo njide mmiri, ihe na-eme ka ọ dịkwuo mma na ịkwado ya, na-eme ka ọ dị mma maka ngwa dị iche iche na ụlọ ọrụ mmepụta ihe.
Atụmatụ nke MHEC
1. Njirimara Rheological
A maara MHEC maka njirimara rheological ya dị mma, na-enye ezigbo viscosity na njirimara eruba maka mkpuchi. Mmetụta dị oke mkpa dị mkpa iji gbochie nkwụsịtụ na ntanye n'oge ngwa ma hụ na mkpuchi na-adịkwa mma.
2. Njide mmiri
Otu n'ime àgwà ndị bụ isi nke MHEC bụ ikike ijide mmiri ya. Nke a dị mkpa karịsịa maka mkpuchi ihe owuwu ka ọ na-enyere aka ịgbatị oge oghere nke agba, na-enye ohere maka nhazi ka mma na ibelata ikike nke ihicha oge.
3. Meziwanye adhesion
MHEC na-eme ka adhesion dịkwuo mma site na ịkwalite wetting elu, na-eme ka mmekọrịta dị mma n'etiti mkpuchi na mkpụrụ. Nke a na-eme ka adhesion dịkwuo mma, ịdịte aka na arụmọrụ mkpuchi n'ozuzu ya.
4. Nkwụsi ike
MHEC na-enye nkwụsi ike na mkpuchi ahụ, na-egbochi nsogbu ndị dị ka nhazi na nkewa nke oge. Nke a na-eme ka mkpuchi ahụ na-edobe ịdị n'otu n'oge ndụ ya na n'oge eji.
Ngwa nke MHEC na mkpuchi ụlọ
1. Agba na primer
A na-eji MHEC eme ihe n'ọtụtụ ebe na nhazi nke ime na mputa agba na primers. Ihe ndị na-eme ka ọkpụkpụ ya na-enyere aka ịbawanye viscosity nke mkpuchi, na-eme ka mkpuchi dị mma na ịrụ ọrụ ngwa ngwa. Ikike ijide mmiri na-eme ka agba agba ga-anọgide na-arụ ọrụ ruo ogologo oge.
2. Ihe mkpuchi ederede
Na mkpuchi ederede, MHEC na-arụ ọrụ dị mkpa n'ịmepụta ederede achọrọ. Njirimara rheological ya na-enyere aka n'otu n'otu kwụsịtụ pigmenti na ihe ndị na-ejuputa, na-ebute njedebe na-agbanwe agbanwe na nke dabara adaba.
3. Stucco na Mortar
A na-eji MHEC mee ihe n'ụdị stucco na ngwa agha iji meziwanye arụmọrụ na nrapado. Ngwongwo ya na-ejigide mmiri na-enyere aka ịgbatị oge na-emeghe, na-eme ka ngwa ngwa dị mma na imecha ihe.
4. Sealants na Caulks
Ihe mkpuchi ihe owuwu dịka ihe mkpuchi na caulk na-erite uru site na njiri mara nke MHEC. Ọ na-enyere aka ịchịkwa nkwụsi ike nke usoro ndị a, na-eme ka akara nke ọma na njikọta.
Uru MHEC dị na mkpuchi ihe owuwu
1. Nkwekọrịta na ịdị n'otu
Ojiji nke MHEC na-eme ka ihe mkpuchi ụlọ na-eme ka ọ bụrụ ihe na-agbanwe agbanwe na ọbụna viscosity, si otú a na-akwalite ọbụna ngwa na mkpuchi.
2. Gbatịkwuo oge mmeghe
Ihe na-ejide mmiri nke MHEC na-agbatị oge oghere nke agba, na-enye ndị na-ese ihe na ndị na-etinye oge maka ngwa ngwa.
3. Meziwanye ikike ịrụ ọrụ
Na stucco, ngwa agha na mkpuchi ụlọ ndị ọzọ, MHEC na-eme ka arụmọrụ ngwa dịkwuo mma, na-eme ka ọ dịkwuo mfe maka ndị na-achọ ihe iji nweta njedebe achọrọ.
4. Enwetara ike ịdịte aka
MHEC na-enyere aka melite nkwụsi ike nke mkpuchi ahụ site n'ịkwalite adhesion na igbochi nsogbu dị ka nkwụsị na nkwụsị.
Methylhydroxyethylcellulose (MHEC) bụ ihe bara uru na mkpuchi ihe owuwu nke nwere rheology dị mkpa na njigide mmiri. Mmetụta ya na nkwụsi ike, ịrụ ọrụ na ịdịte aka na-eme ka ọ bụrụ nhọrọ mbụ na nhazi nke agba, primers, textures, stucco, mortars, sealants na caulk. Ka ụlọ ọrụ na-ewu ihe na-aga n'ihu na-aga n'ihu, MHEC na-anọgide na-abụ akụkụ dị iche iche na nke dị mkpa na mmepe nke mkpuchi ụlọ ọrụ dị elu.
