1. Chemical Ọdịdị na nhazi ọkwa
Cellulose ether bụ ngwakọta polymer kpụrụ site na mgbanwe kemịkalụ nke cellulose eke. Isi ihe mejupụtara ya bụ hydroxyl otu cellulose nke ihe na-eme ka etherifying gbanwee (dị ka vinyl chloride, acetic acid, wdg). Dị ka dị iche iche etherifying iche iche, ọ nwere ike ikewa n'ime dị iche iche nke cellulose ethers, tumadi gụnyere hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC) na methyl cellulose (MC).
2. Njide mmiri
Ihe owuwu ụlọ ọkwa cellulose ether nwere ọmarịcha njide mmiri, nke nwere ike imeziwanye ikike njigide mmiri nke ngwa agha na ihe. Nke a na-eme ka arụmọrụ nke ihe na-arụ ọrụ n'oge a na-ewu ma na-ebelata mgbawa na ike nkwụsị nke mmiri na-ekpochapụ.
3. Ịba ụba
Cellulose ether nwere ezigbo ihe na-emepụta ihe, nke nwere ike imeziwanye mmiri na viscosity nke ihe ụlọ, na-eme ka ọ dị mfe ịrụ ọrụ n'oge a na-ewu ụlọ. Ọkpụkpụ na-enyere aka melite nkwụsi ike nke ihe ma gbochie stratification na sedimentation.
4. Mbelata mmiri
Ruo n'ókè ụfọdụ,cellulose ethersnwere ike ibelata oke mmiri na kọmpat ma ọ bụ ngwa agha, si otú ahụ mee ka ike na ịdịte aka nke ihe ahụ dịkwuo mma. Njirimara a na-eme ka ọ dị mkpa karịsịa na ntinye nke ihe nrụpụta dị elu.
5. arụmọrụ ihe owuwu
Ihe owuwu ụlọ na cellulose ethers nwere arụmọrụ ka mma n'oge a na-ewu ụlọ, nke nwere ike ịgbatị oge ihe owuwu ma belata nsogbu ihe owuwu nke ihicha na-akpata. Tụkwasị na nke ahụ, ha nwekwara ike ime ka adhesion nke ngwa agha dịkwuo mma ma mee ka adhesion nke ihe mkpuchi.
6. Mgbochi mgbape
Cellulose ethers nwere ike imeziwanye mgbape mgbape nke ngwa agha na kọnkịtị ma belata mgbawa nke mgbanwe okpomọkụ na-akpata ma ọ bụ ihicha ihicha. Nke a dị oké mkpa maka nkwụsi ike ogologo oge na ịma mma nke ụlọ.
7. Nkwekọrịta na ndakọrịta
Ụlọ ihe eji eme ụlọ cellulose ethers nwere ezigbo ndakọrịta na ihe dị iche iche nke ụlọ ma nwee ike jikọta ya na ciment, gypsum, polymers na ihe ndị ọzọ na-enweghị emetụta arụmọrụ ha. Ngbanwe a na-eme ka ethers cellulose na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu.
8. Nchekwa gburugburu ebe obibi
Ebe ọ bụ na akụrụngwa nkecellulose etherssitere na eriri osisi, ha onwe ha nwere ụfọdụ njirimara nchekwa gburugburu ebe obibi. N'iji ya na ụfọdụ polymers sịntetik, cellulose ether na-adị mma na gburugburu ebe obibi na-eji na n'efu.
9. Ngwa ngwa
A na-eji cellulose ether ọkwa ihe owuwu ụlọ eme ihe n'ọtụtụ ihe eji ewu ụlọ, gụnyere:
Ngwa ngwa akọrọ: dị ka ngwa ngwa njikọ, plasta ngwa agha, wdg.
Concrete: karịsịa ihe na-arụ ọrụ nke ọma.
Mkpuchi: enwere ike iji ya mee ihe maka mgbidi ime na mpụta, agba latex, wdg.
Ngwaahịa gypsum: dị ka bọọdụ gypsum na gypsum putty.
10. Akpachara anya maka ojiji
Mgbe ị na-eji cellulose ether ihe eji eme ihe, ị kwesịrị ịṅa ntị na isi ihe ndị a:
Tinye dịka nha akwadoro, oke ma ọ bụ ezughi oke ga-emetụta arụmọrụ ikpeazụ.
Gbaa mbọ hụ na ịdị n'otu n'oge ị na-agwakọta iji zere agglomeration.
Mgbe ị na-echekwa, ṅaa ntị na ihe mkpuchi mmiri iji zere mmiri na agglomeration.
Ihe owuwu ụlọ cellulose ether aghọwo ihe mgbakwunye dị mkpa na ụlọ ọrụ ihe owuwu n'ihi njirimara ya pụrụ iche na ngwa ngwa. Site na mmụba na-aga n'ihu nke ụlọ ọrụ ihe owuwu chọrọ maka ịrụ ọrụ ihe, atụmanya ngwa nke cellulose ether ga-abawanye.
