Methyl hydroxyethyl cellulose (MHEC) bụ ihe dị mkpa cellulose ether compound na abụọ mgbanwe nke methylation na hydroxyethylation.Na mkpuchi mmiri, MHEC na-arụ ọrụ dị mkpa na njirimara anụ ahụ na kemịkal pụrụ iche.
I. Njirimara arụmọrụ
Na-ejupụta
Otu hydroxyethyl na methyl dị na MHEC molecular Ọdịdị nwere ike ịmepụta usoro netwọk na ngwọta mmiri, si otú ahụ na-amụba viscosity nke mkpuchi nke ọma.Mmetụta a na-eme ka ọ sie ike na-enyere ya aka inweta ezigbo rheology na obere mkpokọta, si otú ahụ belata ego mkpuchi na ịchekwa ego.
Rheological mgbanwe
MHEC nwere ike inye mkpuchi ahụ ezigbo mmiri mmiri na ihe mgbochi sagging.Ya pseudoplastic e ji mara na-eme ka mkpuchi nwere a elu viscosity na a static steeti, na viscosity nwere ike ibelata n'oge ngwa usoro, nke bụ adaba maka brushing, roller mkpuchi ma ọ bụ spraying arụmọrụ, na n'ikpeazụ nwere ike ngwa ngwa weghachi mbụ viscosity mgbe ewu bụ. emechara, na-ebelata sag ma ọ bụ ntapu.
Njide mmiri
MHEC nwere ezigbo njide mmiri ma nwee ike ịchịkwa ọnụego ntọhapụ nke mmiri nke ọma.Ngwongwo a dị mkpa karịsịa maka igbochi agba nke mmiri na-agbawa, ntụ ntụ na ntụpọ ndị ọzọ n'oge usoro ihicha, ma nwee ike imeziwanye ịdị nro na ịdị n'otu nke mkpuchi n'oge a na-ewu ụlọ.
Emulsion kwụsie ike
Dị ka a surfactant, MHEC nwere ike ibelata elu erughị ala nke pigmenti ahụ na mmiri na-ese na-akwalite ha edo dispersion na isi ihe, si otú emeziwanye nkwụsi ike na larịị nke agba na-ezere flocculation na ọdịda nke pigmenti.
Biodegradability
MHEC sitere na cellulose eke ma nwee ezigbo biodegradability, nke na-eme ka ọ nwee uru doro anya na agba mmiri na-emetụta gburugburu ebe obibi ma na-enyere aka belata mmetọ na gburugburu ebe obibi.
2. Isi ọrụ
Ọkpụrụkpụ
A na-ejikarị MHEC eme ihe dị ka ihe na-agba agba maka agba mmiri na-eme ka ọ dịkwuo mma na-arụ ọrụ ya na àgwà ihe nkiri site n'ịbawanye viscosity nke agba.Dịka ọmụmaatụ, ịgbakwụnye MHEC na agba latex nwere ike ịmepụta ihe mkpuchi otu na mgbidi iji gbochie agba ahụ site na ịkwanye na sag.
Rheology regulator
MHEC nwere ike ịhazigharị rheology nke agba mmiri na-eme ka ọ dị mfe itinye n'oge a na-ewu ụlọ ma nwee ike ịlaghachi ngwa ngwa n'ọnọdụ kwụsiri ike.Site na njikwa rheological a, MHEC na-eme ka arụmọrụ arụ ọrụ nke mkpuchi ahụ dịkwuo mma, na-eme ka ọ dị mma maka usoro mkpuchi dị iche iche.
Onye na-ejigide mmiri
N'ime ihe mkpuchi mmiri, mmiri na-ejide mmiri nke MHEC na-enyere aka ịgbatị oge obibi nke mmiri na mkpuchi ahụ, na-eme ka ihicha ihicha nke mkpuchi, ma gbochie ọgbọ nke mgbawa na ntụpọ elu.
Stabilizer
N'ihi ikike emulsifying ya dị mma, MHEC nwere ike inye aka na mkpuchi mmiri na-emepụta usoro emulsion kwụsiri ike, zere mmiri ozuzo na flocculation nke ihe ndị na-emepụta ihe, ma melite nkwụsi ike nke mkpuchi mkpuchi.
Enyemaka imepụta ihe nkiri
N'oge a na-emepụta ihe nkiri nke mkpuchi mkpuchi, ọnụnọ MHEC nwere ike ịkwalite ịdị n'otu na ịdị nro nke mkpuchi ahụ, nke mere na mkpuchi ikpeazụ nwere ọdịdị dị mma na arụmọrụ.
3. Ihe atụ ngwa
Agba latex
Na agba latex, isi ọrụ nke MHEC na-eme ka ọ dị arọ na njigide mmiri.Ọ nwere ike imeziwanye ihe nhịahụ na ntụgharị nke agba latex, ma hụ na mkpuchi ahụ na-edobe ịdị mma na ịdị n'otu n'oge usoro ihicha.Tụkwasị na nke ahụ, MHEC nwekwara ike ime ka ihe mgbochi na-egbuke egbuke na nke na-eme ka ọ dịkwuo mma nke agba latex, na-eme ka usoro ihe owuwu ahụ dịkwuo mma.
Agba osisi agba mmiri
Na agba osisi na-agba mmiri, MHEC na-eme ka ire ụtọ na ịdị n'otu nke ihe nkiri eserese na-eme ka ọ dịkwuo mma site n'ịgbanwe viscosity na rheology nke agba.Ọ nwekwara ike igbochi agba ka ọ na-akpụ sagging na mmebi n'elu osisi, ma mee ka mmetụta ịchọ mma na ịdịte aka nke ihe nkiri ahụ dịkwuo elu.
Agba ihe owuwu nke mmiri
Ngwa nke MHEC na agba ihe owuwu nke mmiri nwere ike imeziwanye arụmọrụ ihe owuwu na mkpuchi nke agba, karịsịa mgbe mkpuchi mkpuchi dị ka mgbidi na elu ụlọ, ọ nwere ike igbochi nkwụsị na ntanye nke agba.Tụkwasị na nke ahụ, ihe onwunwe mmiri nke MHEC nwekwara ike ịgbatị oge ihicha nke agba, belata nkwụsịtụ na ntụpọ elu.
Agba ụlọ nrụpụta mmiri
Na agba ụlọ ọrụ na-emepụta mmiri, MHEC ọ bụghị nanị na-arụ ọrụ dị ka onye na-emepụta ihe na-ejigide mmiri, ma na-eme ka mgbasa na nkwụsi ike nke agba ahụ dịkwuo mma, nke mere na agba ahụ nwere ike ịnọgide na-arụ ọrụ dị mma na ịdịte aka na gburugburu ụlọ ọrụ mmepụta ihe dị mgbagwoju anya.
IV.Atụmanya ahịa
Site na ụkpụrụ nchebe gburugburu ebe obibi na-esiwanye ike yana mmụba na-arị elu maka ihe owuwu ụlọ akwụkwọ ndụ akwụkwọ ndụ, ahịa ahịa maka agba mmiri na-aga n'ihu na-eto eto.Dị ka ihe mgbakwunye dị mkpa na agba mmiri, MHEC nwere atụmanya ahịa sara mbara.
nkwalite amụma gburugburu
N'ụwa niile, atumatu gburugburu ebe obibi na-esiwanyewanye ike mmachi na ikuku organic compound (VOC) na-agbanwe agbanwe, bụ nke kwalitere ntinye nke mkpuchi mmiri.Dị ka mgbakwunye enyi na enyi na gburugburu ebe obibi, MHEC na-arụ ọrụ dị mkpa na mkpuchi mmiri, na ọchịchọ ya ga-abawanye na mgbasawanye nke ahịa mkpuchi mmiri.
Na-eto eto na-achọsi ike na-ewu ụlọ ọrụ
Ọchịchọ na-arịwanye elu maka obere-VOC, mkpuchi na-arụ ọrụ dị elu na ụlọ ọrụ mmepụta ihe na-akwalitekwa ntinye nke MHEC na mkpuchi ihe owuwu nke mmiri.Karịsịa maka mkpuchi mgbidi dị n'ime na n'èzí, MHEC nwere ike inye ọmarịcha ihe owuwu na ịdịte aka iji gboo mkpa ahịa.
Ịbawanye ngwa nke mkpuchi ụlọ ọrụ
Ọchịchọ na-eto eto maka mkpuchi enyi na gburugburu ebe obibi na mpaghara mmepụta ihe akwalitewokwa ntinye nke MHEC na mkpuchi ụlọ ọrụ mmiri.Dị ka mkpuchi ụlọ ọrụ mmepụta ihe na-etolite n'ebe enyi na enyi na gburugburu ebe obibi na-arụ ọrụ dị elu, MHEC ga-arụ ọrụ dị mkpa karị n'ịkwalite arụmọrụ mkpuchi na njirimara gburugburu ebe obibi.
Methyl hydroxyethyl cellulose (MHEC) na-arụ ọrụ dị mkpa na mkpuchi mmiri na-eme ka ọ dị oke mma, ngbanwe rheology, njide mmiri, nkwụsi ike emulsion na biodegradability.Ngwa ya na mkpuchi mmiri na-adabere na mmiri ọ bụghị nanị na-eme ka arụ ọrụ ụlọ na-arụ ọrụ na mkpuchi mkpuchi nke mkpuchi, ma na-agbasokwa usoro nke nchebe gburugburu ebe obibi na mmepe mmepe.Site n'ịchọ ahịa ahịa na-eto eto maka ịrụ ọrụ dị elu, obere mkpuchi mmiri VOC, atụmanya ngwa nke MHEC na mpaghara a ga-adịwanye karịa.
