Uyini umphumela we- "takitiier" eCellulose Ether ngodaka?

I-Cellulose Ether, ikakhulukazi i-hydroxypropylylylylyl ether (HPMC) iyingxenye ebalulekile ngodaka lwentengiso. Nge-cellulose ether, i-viscosity yayo iyinkomba ebalulekile yokuthi abakhiqizi babantu abakhokhayo banaka, futhi ukubonakala okuphezulu sekucishe kube yisidingo esiyisisekelo somkhakha wesiwonda. Kwabakhiqizi be-cellulose ether yasekhaya, ngenxa yethonya lobuchwepheshe babo, inqubo kanye nemishini, kunzima ukuqinisekisa ukubonwa okuphezulu kwemikhiqizo ye-cellulose ether isikhathi eside.

Kusukela ezifuywayo i-celmulaose ether yangena embonini yodaka ngo-2003, i-viscosity ye-cellulose ether, ikakhulukazi i-hydroxypropylylylylylylylylylylylylylylykyly methyl cellulose ether (HPMC), sekuyinkinga engavikeleki. Ngakolunye uhlangothi, kusukela ekuqaleni kwe-cellulose ether yasekhaya engena embonini yodaka, akukwazi ukuncintisana nemikhiqizo engenisiwe ngokuya ngokuqonda kokusebenza kwesicelo, ukuqina komkhiqizo, kanye nemisebenzi eyengeziwe yomkhiqizo. Ngaphandle kwentengo, okuwukuphela kwendawo ekhanyayo engakhangiswa ingukubonakala okuphezulu; Ngakolunye uhlangothi, i-cellulose yasekhaya ikakhulukazi isebenzisa ukotini ocwengekile njengezinto zokwakha. Uma kuqhathaniswa nemikhiqizo yakwamanye amazwe esebenzisa i-Wood Pulp njengento eluhlaza, kulula ukufezekisa ukubonakala okuphezulu. Yize ngombono wobuchwepheshe besicelo sodaka, ukubonakala okuphezulu akunalo usizo oluhle lohlelo lokusebenza, kepha lo mqondo ogqugquzelwe ngabakhiqizi basekhaya ama-cellulose ether ashiye ukujula kobuchwepheshe bomuntu obomile. Shintsha. I-viscosity ye-cellulose ether iba yinkomba yokuqala yokuthi amabhizinisi odaka anaka ukunaka, futhi isidingo sokubona okuphezulu sesibe yisidingo esiyisisekelo samabhizinisi asekhaya. Kodwa-ke, ngenxa yokushoda kwemvelo emishini yokukhiqiza, ukugeleza kwenqubo, kanye nobuchwepheshe bokukhiqiza, kunzima ezinkingeni ze-ether yasekhaya ye-cellulose ukuqinisekisa ukukhiqizwa kwemikhiqizo yesikhathi eside, ngenkathi abakhiqizi abaningi be-data bafuna kuphela imikhiqizo ephezulu ye-viscosity. Ngaphansi kwesimo samanje, abakhiqizi be-cellulose ether benza konke okusemandleni ukukhulisa i-viscosity yomkhiqizo, ngakho-ke "ukuhlakanipha kwe-enhancer" noma "ukuhlakanipha kwe-enhancer" kwabe sekukhona. "I-Viscosity Enhancer" noma "I-Viscosity Enhancer" empeleni iyi-ejenti yokuwela. Ngokuyinhloko, isakhiwo samangqamuzana e-cellulose ether singena kwinethiwekhi, okukhulisa izithiyo ezihlanganayo ezikhangisweni ezinamanzi we-ether. Ngenxa yalokhu, ikhambi le-cellulose ether aqur aqurity libonisa ukubonakala okuphezulu lapho kuvivinywa, kepha empeleni kuyinto eyi-pseudo-vispusity.

I-Celsulose Ether isetshenziswa emikhiqizweni yodaka njenge-ejenti yokugcina amanzi, isikhungo kanye ne-binder, futhi inomthelela obalulekile ekusebenzeni, okubonakalayo okumanzi, isikhathi sokusebenza kanye nemodi yokwakha yohlelo lodaka. Le misebenzi yenziwa ikakhulukazi ngokwakhiwa kwamabhondi e-hydrogen phakathi kwama-molecule we-cellulose ether nama-molecule wamanzi kanye nokufakwa kwama-molecule e-cellulose ether. Ukungezwa kwe-ejenti ye-viscosity-ethuthukisa empeleni kuthatha ingxenye yama-hydrogen bond ku-cellulose ether molecule ye-cellulose ether kubuthakathaka, futhi ukugcinwa kwamanzi kanye nekhono elimanzi le-cellulose ether kubuthakathaka. Iningi labakhiqizi babantu ababulawa yileli phuzu. Ngakolunye uhlangothi, imikhiqizo yodumbu yasekhaya ilukhuni futhi ayikafinyeleli esigabeni sokunaka kakhulu ukusebenza. Ngakolunye uhlangothi, i-viscosity esiyikhethayo iphakeme kakhulu kunokuvunywa okudingeka ngobuchwepheshe, le ngxenye ibuye inxephezela ngokulahleka komthamo wokugcina amanzi, kepha kunomonakalo osobala ekusebenzeni okumanzi.

I-cellulose ether equkethe i-viscosifier inqubo yokukhiqiza inomthelela ekusebenzeni kokugcina kodaka. Leli phepha liqinisekisile ukusetshenziswa kwemikhiqizo ye-cellulose ngaphansi kwemibandela yenqubo ejwayelekile kanye nemikhiqizo ye-cellulose ether ene-viscosifiers kwinqubo yokukhiqiza kuma-ceramic tile. Ku-glue, umehluko ekutholeni amandla anamathela ngokunamathela ngemuva kokuphulukisa ngaphansi kwezimo ezihlukile.
