Iyini indima ye-methyl hydroxyethyl cellulose Mhec?

I-methyl hydroxyethyl celtulose (Mhec) i-ether eguqulwe ngamakhemikhali. Isakhiwo saso esiyisisekelo siyi-cellulose chain, futhi izakhiwo ezikhethekile zitholakala ngokungenisa ubufakazi be-methylyeth kanye ne-hydroxyethylyl. I-MHEC isetshenziswa kabanzi ezintweni zokwakha, izimbobo, amakhemikhali nsuku zonke, amakhambi kanye nokudla.

1. Indima ezintweni zokwakha

1.1. Ukugcinwa kwamanzi
Ezintweni ezisuselwa ku-monce kanye ne-gypsum, indima enkulu ye-MHEC ukuhlinzeka ngokugcinwa kwamanzi okuhle kakhulu. I-MHEC ingagcina amanzi ekuzithambiseni kalula, eqinisekisa ukuthi izinto zokwenza usimende noma ama-gypsum zithola amanzi anele ngesikhathi senqubo eqinile, ngaleyo ndlela enze ngcono izinga le-hypration kanye ne-crystallization degree of gypsum. Lokhu kusebenza kokugcinwa kwamanzi kudlala indima ebalulekile ekuvikeleni ukuqhekeka okubangelwa ukomisa okusheshayo, ngcono ukusebenza kokwakha kanye nekhwalithi ephezulu.

1.2. Ukuqina kanye nokuthuthukisa ukusebenza
I-MheC ibuye idlale indima ebanzi ku-fortar eyomile, tile anamathela, ama-putty nakweminye imikhiqizo, ethuthukisa ukubonakala nokubonakala kweplastiki yezinto ezibonakalayo. Lo mthelela wokuqina usiza ukuthuthukisa ukusebenza kokwakha, okwenza izinto zibe lula ukusakaza nokulungisa ukusebenza kwezokuxhumana kanye nokunciphisa ukushelela. Ngaphezu kwalokho, umphumela wokuqina we-MHEC ungavikela nokudideka nokugcotshwa ngesikhathi sokwakha, futhi uthuthukise ikhwalithi yokwakha.

1.3. Khulisa Amandla Ebhondi
Ngokungeza i-MHEC kwifomula, amandla ebhondi wezinto ezifana nodaka kanye nokunamathela kungathuthukiswa. Ngesikhathi senqubo enzima, i-MHEC ingakha isakhiwo esinjenge-mesh, esithuthukisa amandla esakhiwo salokho okuqukethwe futhi ngaleyo ndlela kuthuthukise ukusebenza kwamabhondi. Lokhu kubaluleke kakhulu ekuqinisekiseni umphumela wokufaka izibopho zezinto ezifana nezingubo namathayili nge-substrate.

1.4. Thuthukisa anti-sagging
Ngesikhathi senqubo yokufaka odongeni, i-MHEC ingavimba ngempumelelo udaka kusuka ku-sagging, yenza umfaniswano wokubumba olinganayo kanye nobushelelezi. Ku-tile anamathela, kungathuthukisa futhi ukusebenza kwe-anti-slip of adhesive, okwenza amathayili mancane amathuba okuthi ashise ngesikhathi senqubo yokugoqa.

2 Indima Ekuhlotsheni

2.1. Ukuqina nokuguqulwa kwe-rheological
I-MHEC isetshenziswa njengesikhulu ku-Latex Paints, upende kawoyela nezinye izimbotshana zokushintsha izakhiwo zesimbozo se-coating. Ingagcina upende ekuboneni okufanele, ukuze kube nokusezingeni elihle ngesikhathi sokwakha futhi kugwenywe amamaki abunjiwe kanye namamaki. Ngaphezu kwalokho, umphumela wokuqina we-MHEC futhi wenze upende ube nokuqina okuhle kwesitoreji lapho i-static.

2.2. I-Emulsation kanye nokuzinza
I-MHEC ine-emulsation kanye nomphumela wokuzinza. Ingazinza imibala kanye nama-fillers opendweni, ivikele imibala ekuxazululeni nasekuhlanganeni, ithuthukise ukuqina kanye nokufana kopende, futhi ngaleyo ndlela ithuthukise ikhwalithi ye-coating.

2.3. Ukugcinwa kwamanzi kanye nefilimu ukwakha
Ngopende, umphumela wokugcinwa kwamanzi we-MHEC ungabambezela ukuhwamuka kwamanzi, wandise ijubane lokwakheka kwefilimu, uqinisekise ukuqina kanye nokufana kwefilimu, futhi ngenxa yalokho uthuthukise ukuqina kanye nomphumela wokuhlobisa ifilimu.

3. Indima emikhiqizweni yansuku zonke yamakhemikhali

3.1. Ukuqina
Emikhiqizweni yamakhemikhali yansuku zonke enjengezihlanzi, ama-sanitizers ezandla, kanye nokuhlanza kobuso, i-MHEC, njengomuntu omkhulu, kungakhulisa ngempumelelo ukubonwa komkhiqizo bese wenza umkhiqizo wokuthola umsebenzi kanye nomphumela wohlelo lokusebenza.

3.2. Isitabili
I-MHEC ibuye isebenze njenge-stabilizer emikhiqizweni yansuku zonke yamakhemikhali, engazinza izinto ezimisiwe kumkhiqizo, ivikele ukuhanjiswa kwezulu nokuqina, futhi igcine umfaniswano womkhiqizo ngekhwalithi ngesikhathi sokugcina isikhathi eside.

3.3. Ukufudumala nokuvikela
Ngenxa yokusebenza okuhle kokugcinwa kwamanzi kwe-MHEC, kungahlinzeka ngemiphumela enomswakama yemikhiqizo yamakhemikhali yansuku zonke njengemikhiqizo yokunakekelwa kwesikhumba, ukuvikela ifilimu elinomswakama wesikhumba, futhi kwakha ifilimu evikelayo endaweni yokuvikela isikhumba ukuze uthuthukise ukusebenza komswakama nokuvikela umkhiqizo.

4. Indima Emikhakheni Nokudla

4.1. Ukukhishwa okulawulwayo nokugoqa

I-MHEC ivame ukusetshenziswa njengezinto ezihlanganayo ne-ejenti yokukhishwa elawulwayo yamathebhulethi enkambini yezemithi. Ingalawula isilinganiso sokukhishwa kwezidakamizwa, ithuthukise ukuqina nokuqina kokusebenza kwezidakamizwa, futhi ithuthukise ukubukeka nokuqina kwamathebulethi.

4.2. Ukuqina nokuqina
Embonini yokudla, i-MHEC isetshenziswa njengesikhudlwana kanye ne-stabilizer emikhiqizweni ehlukahlukene, amasoso, nemikhiqizo yobisi ukuthuthukisa ukunambitheka kanye nokuthungwa kokudla, ukuvimba ukuhlukaniswa kokudla kanye nezulu, futhi kunwebe impilo yeshalofu yokudla.

4.3. Izithasiselo Zokudla
Njengesengezo sokudla, i-MHEC isetshenziselwa ukwenza ngcono ukuthokomala, ukugcinwa kwamanzi kanye nokuqina kwenhlama, okwenza ukuthungwa kwezimpahla ezibhakiwe njengezinkwa namakhekhe athambile futhi ukunambitheka okungcono.

5. Izakhiwo zenyama nezamakhemikhali

5.1. I-solubity yamanzi
I-MHEC ingancishiswa kuwo womabili amanzi abandayo nawashisayo ukwakha isixazululo esibonakalayo, esibonakalayo. Le solibity yamanzi yenza kube lula ukuhlakazeka nokusebenzisa ezinhlobonhlobo zezicelo.

5.2. Ukuqina kwamakhemikhali
I-MHEC inokuqina okuhle kwamakhemikhali, ukubekezelela okuqinile kuma-acid, ama-alkali kanye nosawoti, futhi akulula ukudicilela phansi, okwenza kube nohlu olubanzi lwamathemba wohlelo lokusebenza emikhiqizweni ehlukahlukene yamakhemikhali.

5.3. Biocomthation
Kusukela i-MHEC i-ether ye-cellulose engeyona eye-ionic, ine-biocomtic enhle futhi ayicasuli esikhunjeni nasemzimbeni womuntu, ngakho-ke isetshenziswa kabanzi kumakhemikhali nsuku zonke nemithi.

Njenge-ether esebenza ngokusebenza, i-Mhec idlala indima ebalulekile emikhakheni eminingi efana nezinto zokwakha, izimbobo, amakhemikhali nsuku zonke, amakhemikhali kanye nokudla ngenxa yokugcinwa kwamanzi okuhle, ukuqina, ukunamathela kanye nokuqina kwamakhemikhali. Uhlelo lwayo olubanzi alugcini nje ngokuthuthukisa ukusebenza nekhwalithi yemikhiqizo, kepha futhi luhlinzeka ngokusekelwa okubalulekile kwezinto ezibonakalayo zentuthuko yezobuchwepheshe kanye nokwenza izinto ezintsha ezimbonini ezahlukahlukene.
