Cellulose ether bụ ihe dị mkpa kemịkalụ nke a na-ejikarị na ngwa ngwa ntụ ntụ na-ewu ụlọ. Ọ bụ ụdị mkpụrụ ndụ cellulose nke a na-emezi site na hydroxyl dị iche iche na mkpụrụ ndụ cellulose, gụnyere hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), hydroxyethylcellulose (HEC), wdg. Ndị a cellulose ethers nwere ọrụ dịgasị iche iche na ihe ndị magburu onwe ya, na-enye ha uru dị ukwuu na ngwa agha ihe owuwu.
(1) Melite ịrụ ọrụ ihe owuwu
1. Melite ịrụ ọrụ
Cellulose ethers na-arụ ọrụ dị ka ndị na-ebu ibu na ndị na-ejigide mmiri na ngwa agha. Ọ nwere ike melite viscosity na thixotropy nke ngwa agha, na-eme ka ọ dịkwuo mfe ịgbasa na ire ụtọ, si otú ahụ na-emeziwanye mma na arụmọrụ nke ihe owuwu. Tụkwasị na nke ahụ, cellulose ether nwere ike igbochi ngwa agha ahụ kewapụ n'oge usoro ihe owuwu ahụ, na-eme ka ịdị n'otu na mma mmachi nke ngwa agha ahụ.
2. Meziwanye adhesion nke ngwa agha
Cellulose ether nwere ike imeziwanye nrapanye nke ngwa agha na mkpụrụ. Nke a dị mkpa karịsịa maka usoro dịka tiling ma ọ bụ plasta nke chọrọ njikọ siri ike na mkpụrụ. Cellulose ether na-enye ohere ka ngwa agha ahụ nọgide na-enwe ezigbo nrapado na gburugburu iru mmiri ma ọ bụ akọrọ, na-ezere nsogbu nke ịwụfu na mgbawa nke na-akpata site na nkwụsị zuru ezu.
(2) Kwalite akụrụngwa anụ ahụ nke ngwa agha
1. Meziwanye njigide mmiri
Njide mmiri bụ otu n'ime ihe ndị dị mkpa nke cellulose ether, nke na-enye ohere ka ngwa agha ahụ nọgide na-enwe mmiri zuru ezu tupu ya agbasie ike. Àgwà ọma a nwere ike igbochi evaporation nke mmiri na-akaghị aka ma belata mmiri na-efu na ngwa ngwa, si otú ahụ na-emeziwanye mmeghachi omume hydration ciment ma na-akwalite nkwalite ike na ịdịte aka nke ngwa agha ahụ.
2. Welie ike nke ngwa agha
Site na mmetụta njide mmiri nke cellulose ether, simenti dị na ngwa ngwa nwere ike ị nweta mmiri zuru oke iji mepụta ngwaahịa hydration siri ike. Nke a na-enyere aka melite ike mkpakọ na mgbanwe nke ngwa agha ahụ. Na mgbakwunye, cellulose ether nwekwara ike ibelata mgbawa nke mbelata nke ngwa agha na-akpata n'oge usoro siri ike ma nọgide na-enwe ike na nkwụsi ike nke ngwa agha ahụ.
3. Melite nguzogide friza-thaws
Cellulose ethers na-abawanye njupụta nke ngwa agha ahụ, na-eme ka ọ bụrụ ihe na-eguzogide ọgwụ na-ekpo ọkụ na-agbaze okirikiri. Nkwụsi ike a na-ekpo ọkụ dị mkpa karịsịa maka ngwa agha ndị a na-eji na mpaghara oyi, nke nwere ike ịgbatị ndụ ọrụ nke ụlọ ahụ nke ọma ma belata ụgwọ ọrụ.
(3) Melite mgbanwe gburugburu ebe obibi nke ihe owuwu
1. Gbatịkwuo oge mmeghe
Cellulose ethers nwere ike ịgbatị oge oghere nke ngwa agha ahụ, ya bụ, oge ngwa agha ahụ na-anọgide na-arụ ọrụ mgbe etinyechara ya. Nke a bara uru karịsịa maka iwu ụlọ na okpomọkụ dị elu ma ọ bụ gburugburu akọrọ, na-ebelata nsogbu nke ike ngwa ngwa ngwa ngwa nke na-emetụta àgwà ụlọ.
2. Melite nguzogide sag
Mgbe a na-arụ ụlọ n'elu kwụ ọtọ, ngwa agha na-achọ ịsacha ma ọ bụ sag. Cellulose ether na-eme ka arụ ọrụ mgbochi sag nke ngwa agha dịkwuo mma site na ịgbasa ngwa ngwa, na-ahụ na ngwa agha ahụ nwere ike ịkwado ya n'elu elu kwụ ọtọ ma na-ezere ntụpọ ụlọ.
(4) Uru gburugburu ebe obibi na akụ na ụba
1. Melite iji ihe eji eme ihe
Cellulose ether nwere ike imeziwanye arụmọrụ na ịrụ ọrụ nke ngwa agha, ma belata mkpofu nke ihe n'oge usoro ihe owuwu. Nke a nwere mkpa akụ na ụba dị mkpa maka nnukwu ụlọ ọrụ na-ewu ụlọ, nke nwere ike ibelata ọnụ ahịa ihe onwunwe ma melite uru akụ na ụba nke ihe owuwu.
2. Enyi na gburugburu ebe obibi
Cellulose ethers bụ ihe ndị sitere na bio na enwechaghị mmetụta na gburugburu ebe obibi n'oge mmepụta na ngwa ha. Na mgbakwunye, ọ nwere ike belata mmetọ nke abụọ nke ọma n'oge a na-arụ ngwa agha, dị ka uzuzu na mkpofu, wee mezuo ihe achọrọ nke ụlọ akwụkwọ ndụ akwụkwọ ndụ ọgbara ọhụrụ.
(5) Ihe atụ ngwa a kapịrị ọnụ
1. Tile nrapado
Na seramiiki tile adhesives, mgbakwunye nke cellulose ether nwere ike imeziwanye arụmọrụ, njide mmiri na ike njikọ nke nrapado, ma melite mmetụta njikọ na ịrụ ọrụ nke taịlị seramiiki.
2. Mgbidi plasta mgbidi
Cellulose ether na plasta ngwa agha na-eme ka arụmọrụ na mgbochi sag rụọ ọrụ nke ngwa agha ahụ, na-eme ka ịdị nro na ịdị mma elu nke akwa akwa akwa akwa, na-ebelata ntụpọ ihe owuwu na ịrụzi ọrụ.
3. Ngwa agha na-ebuli onwe ya
Cellulose ether na ngwa agha na-edozi onwe ya na-enyere aka imeziwanye mmiri na njigide mmiri nke ngwa agha ahụ, na-ekwe ka ọ na-eme ka ala na-akpaghị aka na-eme ka ọ dịkwuo mma ma na-eme ka ọ dị nro na ịrụ ọrụ nke ala.
Na nchịkọta, cellulose ether nwere uru dị ịrịba ama na ntinye nke ntụ ntụ ntụ na-arụ ọrụ ihe owuwu. Ọ bụghị naanị na ọ na-eme ka arụ ọrụ ihe owuwu na ihe anụ ahụ nke ngwa agha dịkwuo mma, kamakwa ọ na-eme ka mgbanwe gburugburu ebe obibi na uru akụ na ụba nke ụlọ. Ngwa nke cellulose ether na-eme ka ịdị mma na ịdịte aka nke ụlọ mgbidi na-akwalite mmepe mmepe nke ọrụ ihe owuwu. Site na ọganihu teknụzụ ihe owuwu na-aga n'ihu, cellulose ether ga-enwe atụmanya ngwa sara mbara na ngwa ngwa wee bụrụ ihe dị mkpa ma dị mkpa maka ihe owuwu ọgbara ọhụrụ.
