1. Njirimara nke cellulose ethers
Cellulose ether bụ ngwakọta polymer ewepụtara site na eriri osisi eke. A na-eme ya ka ọ bụrụ ihe soluble, na-agbatị, na-ejigide mmiri na ihe nkiri site na mmeghachi omume etherification. Isi njirimara ya gụnyere:
Njide mmiri: Cellulose ether nwere ikike ijide mmiri dị mma, nke nwere ike ịchịkwa ntọhapụ nke mmiri n'ime ihe owuwu ụlọ, na-ezere ikpochapụ mmiri dị ukwuu, ma si otú a na-emeziwanye arụmọrụ ihe owuwu.
Ọkpụkpụ: A na-ejikarị cellulose ether eme ihe dị ka ihe na-esi ísì ụtọ na ihe owuwu ụlọ, nke nwere ike ime ka viscosity nke ihe ahụ dịkwuo mma ma melite arụmọrụ ya n'oge a na-ewu ụlọ.
Adhesion: Na ngwa ngwa agwakọta akọrọ na adhesives, ether cellulose nwere ike iji mee ihe dị ka ihe nkedo iji mee ka adhesion dị n'etiti ihe na isi.
Rheological mgbanwe: Cellulose ether nwere ike melite rheological Njirimara nke ụlọ ihe, nke mere na ha nwere ike ịnọgide na-enwe ezi fluidity na thixotropy n'okpuru dị iche iche ewu ọnọdụ, nke dị mma maka ewu na ịkpụzi.
Mgbochi-sagging: Cellulose ether nwere ike imeziwanye ihe na-egbochi ihe na-adịghị mma nke ihe ahụ, karịsịa mgbe a na-arụ mgbidi kwụ ọtọ, nke nwere ike igbochi ngwa agha ma ọ bụ agba nke ọma.
2. Ngwa nke cellulose ether na ihe eji ewu gburugburu ebe obibi
Ngwa ngwa agwakọta akpọnwụ
Ngwa ngwa agwakọta akpọọ nkụ bụ ihe a na-ewu ewu na gburugburu ebe obibi, nke a na-ejikarị na plasta mgbidi, nhazi ala, ịtọ tile na ihe nkiri ndị ọzọ. A na-eji cellulose ether eme ihe n'ọtụtụ ebe na ngwa ngwa agwakọta akpọnwụ akpọnwụ, na-emekarị na-arụ ọrụ nke njide mmiri, njupụta na njikọ. Cellulose ether nwere ike ime ka ngwa agha hapụ mmiri nke ọma n'oge usoro ihicha, gbochie mgbawa nke oke mmiri na-efunahụ, ma kwalite ike njikọ nke ngwa agha ahụ iji hụ na ike ya na ịdịte aka ya mgbe e wuchara ya.
Ihe mkpuchi ihe owuwu
A na-eji cellulose ether eme ihe dị ka ihe na-eme ka ọkpụkpụ na mmiri na-eme ka mmiri dị na mkpuchi ụlọ na-adabere na mmiri iji mee ka arụ ọrụ ụlọ na njedebe ikpeazụ nke mkpuchi ahụ dịkwuo mma. Ọ nwere ọmarịcha ihe nkiri na-emepụta ihe na nhazi rheological, nke nwere ike hụ na mkpuchi ahụ nwere mgbasa ozi dị mma n'okpuru ngwá ọrụ ihe owuwu dị iche iche. Tụkwasị na nke ahụ, cellulose ether nwekwara ike imeziwanye ihe mgbochi na-egbochi ihe mkpuchi nke mkpuchi ahụ, na-eme ka ọ ghara ịda mbà mgbe a na-etinye ya n'elu ebe kwụ ọtọ, si otú a na-enweta ihe mkpuchi otu.
Tile nrapado
Adhesives tile bụ ngwa dị mkpa n'ọhịa nke ihe eji ewu ụlọ na gburugburu ebe obibi. Cellulose ethers nwere ike imeziwanye njide mmiri na ihe mgbochi mgbochi nke adhesives ma kwalite ike njikọ dị n'etiti taịl nile na oyi akwa. N'oge a na-ewu ụlọ, mgbakwunye nke cellulose ethers na-eme ka arụmọrụ nke tile adhesives dịkwuo mma, ma na-eme ka oge na-emeghe ogologo oge, nke dị mma maka ndị na-arụ ọrụ ụlọ iji gbanwee.
Putty ntụ ntụ
A na-eji ntụ ntụ Putty mee ihe maka nhazi mgbidi na nrụzi. Njide mmiri nke cellulose ether nwere ike igbochi mgbawa ma ọ bụ daa site na ihicha putty ngwa ngwa mgbe e wuchara ya. N'otu oge ahụ, ihe onwunwe ya na-eme ka ọ dịkwuo mma na-enyere aka melite mkpuchi na ire ụtọ nke putty, na-eme ka ihe owuwu ahụ dịkwuo mma.
Ihe n'ala na-edozi onwe ya
Ngwa nke cellulose ether n'ime ihe ndị dị n'ala na-edozi onwe ya bụ karịsịa iji meziwanye mmiri mmiri ya na njide mmiri, hụ na ihe ahụ nwere ike ịme ngwa ngwa ma kesaa ya n'oge a na-ewu ala, na-egbochi ala ka ọ ghara ịgbawa ma ọ bụ nsị nke mmiri na-efunahụ.
3. Uru gburugburu ebe obibi nke cellulose ether
Isi iyi eke, mmepụta gburugburu ebe obibi
A na-eme cellulose ether nke cellulose eke ma na-emegharị ya. Enweghị gas na-emerụ emerụ na mmiri mmiri na-ekpofu ihe na-emepụta n'oge usoro mmepụta ya, mmetụta na gburugburu ebe obibi dị ntakịrị. Na mgbakwunye, e jiri ya tụnyere ihe mgbakwunye kemịkalụ ọdịnala, cellulose ether adịghị emerụ ahụ mmadụ ma nwee ike weda ya n'ụzọ nkịtị. Ọ bụ ihe na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi.
Belata oriri ike ihe ma melite arụmọrụ ihe owuwu
Cellulose ether nwere ike imeziwanye arụmọrụ ihe owuwu nke ihe owuwu ụlọ, mee ka owuwu ha dịkwuo mfe na ngwa ngwa, ma belata ihe mkpofu na ike oriri. Tụkwasị na nke ahụ, n'ihi njide mmiri dị mma, cellulose ether nwere ike ibelata ọchịchọ nke mmiri na-ewu ma na-echekwa ihe onwunwe ọzọ.
Meziwanye ịdịte aka nke ihe ụlọ
Cellulose ether nwere ike imeziwanye ịdịte aka nke ihe eji ewu ụlọ na gburugburu ebe obibi, mee ka ndụ ọrụ nke ụlọ dịkwuo ogologo, belata mkpa maka ịrụzi ma ọ bụ dochie anya n'ihi ịka nká ma ọ bụ mmebi nke ihe owuwu ụlọ, si otú ahụ na-ebelata ihe onwunwe na mmepụta ihe na-emepụta ihe.
Dị ka ihe mgbakwunye gburugburu ebe obibi, nchekwa na arụ ọrụ nke ọma, ether cellulose ether ejiriwo ọtụtụ ebe a na-eji ihe ụlọ eme ihe na gburugburu ebe obibi dị ka ngwa agha agwakọtara akọrọ, akwa tile, na mkpuchi ụlọ. Ọ bụghị naanị na ọ ga-eme ka arụ ọrụ ihe owuwu nke ụlọ na-arụ ọrụ dịkwuo mma ma mee ka ihe dị mma dịkwuo mma, kamakwa ọ nwere uru dị ukwuu na gburugburu ebe obibi. N'ọdịnihu nke ihe owuwu ihe owuwu, na-aga n'ihu na-aga n'ihu nke ihe nchebe gburugburu ebe obibi chọrọ, atụmanya ngwa nke cellulose ether ga-aba ụba.
