Cellulose Ether (CE) bụ ihe a na-agbanwe agbanwe nke polymer sitere na cellulose eke ma na-ejikarị eme ihe na ihe owuwu ụlọ, mkpuchi, ọgwụ, ihe ịchọ mma na ubi ndị ọzọ. E nwere ụdị cellulose ethers dị iche iche, ndị nkịtị gụnyere hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC) na methylcellulose (MC). Na ngwa dị iche iche, cellulose ethers egosipụtawo uru dị ịrịba ama n'ihe gbasara ịdịte aka na arụmọrụ, na-aghọ akụkụ dị mkpa n'ịkwalite àgwà ihe onwunwe na ndụ ọrụ.
1. Melite arụmọrụ ihe owuwu
N'ihe gbasara ihe owuwu ụlọ, a na-ejikarị cellulose ethers eme ihe dị ka ndị na-ekpo ọkụ, ndị na-ejide mmiri na ndị na-ekekọta ihe. N'ime ngwa agha, gypsum na ihe ndị dabeere na ciment, mmetụta nke cellulose ether na-eme ka ihe ahụ dịkwuo mma na plastik n'oge a na-ewu ụlọ, na-ezere ọbara ọgbụgba na nsogbu nkewa. Cellulose ether na-emekwa ka ike njikọ nke ihe ahụ dịkwuo mma, na-ahụ na enwere ike kesaa ihe ahụ n'otu oge n'oge a na-arụ ọrụ ihe owuwu ma nwee mma mmachi na mkpụrụ.
Hydroxypropyl methylcellulose (HPMC) nwere ike ime ka arụ ọrụ nke ngwa agha dịkwuo mma, na-eme ka ọ dị mfe itinye na obere ihe ọ ga-adaba ala, karịsịa n'ihe owuwu kwụ ọtọ. Na mgbakwunye, mmetụta retarding nke cellulose ether nwere ike ịgbatị oge arụ ọrụ nke ngwa agha, nke bara uru maka ịrụ ọrụ dị mgbagwoju anya. Atụmatụ ndị a na-emeziwanye arụmọrụ ụlọ na ịdị mma n'ihe gbasara ibelata mkpofu ihe na mmejọ ihe owuwu.
2. Ezigbo njide mmiri
Otu n'ime ihe ndị dị mkpa nke cellulose ethers bụ ezigbo njide mmiri ha. Njide mmiri na-ezo aka n'ikike nke cellulose ether iji nweta ma na-ejigide mmiri n'ime ihe ahụ, na-egbochi evaporation na-akaghị aka ma ọ bụ mmiri mmiri, si otú ahụ na-ahụ ike na ịdịte aka nke ihe onwunwe mgbe e wuchara ya. N'ime ihe ndị e ji ewu ụlọ dị ka ciment dabeere na ngwaahịa gypsum, mmetụta na-ejide mmiri nke cellulose ether na-eme ka mmiri nwee ike ịbanye n'ụzọ zuru ezu na usoro mmeghachi omume n'oge mmeghachi omume hydration, na-ezere ihe na-agbawa ihe na ike na-ezughị ezu nke mmiri na-efunahụ aka.
Ngwongwo njide mmiri dị mkpa karịsịa maka owuwu nke obere oyi akwa. Dịka ọmụmaatụ, n'oge usoro tiling, cellulose ethers nwere ike inye aka gbochie mmiri dị na ngwa ngwa ka ọ ghara ịla ngwa ngwa, si otú a na-eme ka adhesion na ịdịte aka nke taịl nile dịkwuo mma. N'otu aka ahụ, n'ọhịa nke mkpuchi, cellulose ethers nwere ike igbochi evaporation nke mmiri n'oge na-adịghị anya, na-ekwe ka mkpuchi ahụ mepụta otu uwe na oke elu, na-agbatị ndụ nke mkpuchi na ibelata mkpa maka nlekọta na-esote.
3. Meziwanye nguzogide ihu igwe nke ihe
Ngwa nke cellulose ethers nwekwara ike welie ihe onwunwe si weatherability, ya bụ ya iguzogide ihe gburugburu ebe obibi dị ka mmiri mmiri, UV ụzarị, ihu igwe na oké okpomọkụ. Nke a dị oke mkpa maka ịdịte aka nke ihe owuwu ụlọ. Dịka ọmụmaatụ, ntinye nke cellulose ethers na mkpuchi nwere ike imeziwanye ihe nkiri na-emepụta ihe nkiri nke mkpuchi ahụ ma mee ka njupụta nke mkpuchi ahụ dịkwuo elu, si otú ahụ na-eme ka ihe mkpuchi na-eguzogide ultraviolet radieshon na igbochi ịda mbà n'obi na ịka nká.
N'ime ihe ndị sitere na ciment, cellulose ether nwere ike ime ka njigide mmiri dịkwuo mma, belata mmetụta nkwụsị nke ihicha n'oge a na-eme ka ciment sie ike, ma belata ihe ize ndụ nke ịgbawa, si otú ahụ na-eme ka nguzogide oyi-ịza oyi na nkwụsị ihu igwe. Nke a na-enye ohere ka ụlọ ahụ nọgide na-eguzosi ike n'ezi ihe na ihe ịchọ mma ya ruo ogologo oge na ọnọdụ ihu igwe siri ike.
4. Magburu onwe thickening na rheology ukpụhọde
Mmetụta siri ike nke cellulose ether na ngwọta mmiri na-enye ya ohere ịhazigharị ihe ndị na-ahụ maka rheological nke ihe onwunwe (dị ka viscosity, mkpụrụ nrụgide, wdg), si otú ahụ na-eme ka nkwụsi ike na ịdị mfe nke ihe eji eme ihe. Na mkpuchi na agba, cellulose ethers na-edozi viscosity nke agba ahụ iji hụ na ọ naghị agbaze ma ọ bụ na-agbapụta n'oge ngwa ma na-emepụta ihe dị mma, ọbụna mkpuchi. Nke a ọ bụghị nanị na-eme ka njikwa njikwa nke ihe owuwu dịkwuo mma, kamakwa ọ na-eme ka nkwụsị nke mkpuchi na-eyi na mgbawa nke mkpuchi.
Cellulose ethers na-arụkwa ọrụ dị mkpa n'ịkwado ihe ala nke onwe. Ọrụ ngbanwe ya na-eme ka o sie ike na nke rheological na-eme ka ihe ahụ na-eme ka ihe dị mma na-eme ka mmiri dị mma na nhazi onwe ya n'oge usoro ịwụsa, na-ebelata ọgbọ nke egosipụta na ntụpọ, na n'ikpeazụ na-eme ka ewepụghị na ịdịte aka nke ala.
5. Mee ka mgbape na-eguzogide ihe
Njide mmiri na mmetụta siri ike nke cellulose ether na-enyere aka ịchịkwa ngwa ngwa ihicha ihe ma zere mbelata na nsogbu mgbawa nke oke mmiri na-efunahụ. Karịsịa n'ime ngwa ngwa na ihe ndị sitere na ciment, cellulose ether nwere ike ịgbasa mmiri dị n'ime ihe ahụ ma belata nkwụsị nke nkwụsịtụ. Na mgbakwunye, njirimara njikọta ya ka mma na-emekwa ka ihe ahụ nwee ike ijikọ nke ọma na mkpụrụ ma welie mgbape mgbape nke ihe owuwu niile.
N'ihe ndị dị na gypsum, cellulose ethers na-egbochi mgbawa elu nke mmiri na-efunahụ ngwa ngwa, na-eme ka mgbidi na mgbidi na-ekpuchi mgbidi ma dị mma n'oge ihicha. Nkwụsị mgbape a abụghị naanị na-eme ka ọdịdị ọdịdị dị mma dịkwuo mma, kamakwa ọ na-agbatị ndụ ọrụ ya.
6. Meziwanye nguzogide corrosion na nguzogide kemịkalụ
Cellulose ethers nwekwara ike melite corrosion na kemịkalụ nguzogide nke ihe na ụfọdụ ngwa. Site n'ime ka ihe ahụ dị ntakịrị ma na-eguzogide mmiri karị, cellulose ethers nwere ike ibelata ọgụ nke kemịkal na-emerụ ahụ ma ọ bụ mmiri na ihe ahụ. Nke a dị oke mkpa na mpaghara ụfọdụ pụrụ iche, dị ka osisi kemịkalụ, gburugburu mmiri ma ọ bụ gburugburu iru mmiri dị elu.
Ngwa nke cellulose ethers na mkpuchi mmiri na-adịghị na-eme ka ọ dịkwuo ogologo oge, ma na-eme ka nguzogide kemịkalụ dị ka acid, alkalis, na salts, si otú ahụ na-agbatị ndụ ọrụ nke ihe onwunwe na ibelata ego nke nrụzi na ndochi.
7. Green gburugburu ebe obibi na mmepe mmepe
Cellulose ether bụ ihe na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi n'ihi na ọ na-esite na cellulose osisi sitere n'okike ma bụrụ ihe na-emebi emebi. E jiri ya tụnyere ihe polymer sịntetik, cellulose ethers enwechaghị mmetụta na gburugburu ebe obibi ma ghara ịhapụ ihe ndị na-emerụ ahụ n'oge usoro mmepụta. Ya mere, ngwa ngwa nke cellulose ethers na-ezute ihe ndị a chọrọ ugbu a maka nchebe gburugburu ebe obibi na mmepe na-adịgide adịgide na ụlọ ọrụ mmepụta ihe.
Uru nke cellulose ethers n'ihe gbasara ịdịte aka na arụmọrụ na-egosipụtakarị na njigide mmiri ha dị mma, na-eme ka ọ dị arọ, nrapanye na nguzogide ihu igwe. Ọ bụghị naanị na ọ na-eme ka arụ ọrụ ihe owuwu ụlọ dịkwuo mma, kamakwa ọ na-eme ka mgbape mgbape nke ihe ahụ dịkwuo elu, ịdịte aka na nkwụsị nke corrosion, na-agbatị ndụ ọrụ nke ihe ahụ. Tụkwasị na nke ahụ, akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi nke cellulose ether na-emekwa ka ọ bụrụ akụkụ dị mkpa nke mmepe nke ihe owuwu ụlọ n'ọdịnihu.
