I-Hydroxyethyl Methyl Cellulose

I-HydroxyethylMi-ethylCi-ellilose(HEMC) ibizwa nangokuthi iMethyl Hydroxyethyl Cellulose (MHEC), yonakumhlopheizinto ezisuselwa ku-methyl cellulose etherimpuphu, ayinaphunga futhi ayinambitheki, iyancibilika: cishe ayincibiliki emanzini ashisayo, i-acetone, i-ethanol, i-ether kanye ne-toluene. Iyancibilika emanzini nakwezinye izinyibilikisi eziphilayo, njenge-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane, ngezilinganiso ezifanele. Isixazululo sinomsebenzi wobuso, ukucaca okuphezulu kanye nokusebenza okuzinzile. Imininingwane ehlukene yemikhiqizo inezinga lokushisa elihlukile lejeli, okuyizimpawu ze-Hydroxyethyl zokushisa.Mi-ethylCi-ellilose(I-HEMC). Ukuncibilika kuyashintsha nge-viscosity. Uma i-viscosity iphansi, kulapho ukuncibilika kuba kukhulu khona. Imininingwane ehlukene ye-HydroxyethylMi-ethylCi-ellilose(I-HEMC)babe nomehluko othile ekusebenzeni.

Ukuqedwa kwe-HydroxyethylMi-ethylCi-ellilose(I-HEMC)emanzini akuthintwa yi-pH. Ithonya lenani. I-HydroxyethylMi-ethylCi-ellilose(I-HEMC)iyancibilika emanzini ashisayo, futhi ayincibiliki ezincibilikisini eziningi eziphilayo. I-Hydroxyethyl ehlungwe ngaphezuluMi-ethylCi-ellilose(I-HEMC)ihlakazeka emanzini abandayo ngaphandle kokuhlangana futhi incibilika kancane, kodwa ingancibilika ngokushesha ngokushintsha inani layo le-pH libe ngu-8 ~ 10. Ukuqina kwe-ph: ushintsho lwe-viscosity luncane ebangeni le-ph kusukela ku-2 kuya ku-12, futhi i-viscosity iyancipha ngale kwalolu hlu.

Indlela yokuncibilikisa

Engeza ingxenye eyodwa kwezintathu yenani elibekiwe lamanzi ahlanzekile esitsheni. Faka i-hydroxyethyl methyl cellulose (I-HEMC) ngaphansi kokuxuba ngesivinini esiphansi, bese uvuselela kuze kube yilapho zonke izinto zimanzi ngokuphelele. Engeza ezinye izithako zefomula bese uxuba kahle. Namathisela enanini elibekiwe lamanzi abandayo ukuze uphole futhi uncibilike.

Izicelo:

1. Udaka oluxubile olomile

Ukugcinwa kwamanzi amaningi kungamanzisa usimende ngokugcwele, kwandise kakhulu amandla okubopha, futhi ngesikhathi esifanayo kungandisa ngokufanele amandla okudonsa kanye namandla okusika, kuthuthukise kakhulu umphumela wokwakha futhi kwandise ukusebenza kahle komsebenzi.

2. I-putty yodonga

I-cellulose ether ku-putty powder idlala indima ekugcinweni kwamanzi, ukubopha kanye nokuthambisa, igwema imifantu kanye nokuphelelwa amanzi emzimbeni okubangelwa ukulahleka kwamanzi ngokushesha kakhulu, futhi ngesikhathi esifanayo ithuthukisa ukunamathela kwe-putty, inciphise ukwehla kwesimo ngesikhathi sokwakha, futhi yenze ukwakhiwa kube lula.

1. Iplasta yeGypsum

Emikhiqizweni yochungechunge lwe-gypsum, i-cellulose ether idlala indima yokugcina amanzi nokwandisa ukuthambisa. Ngesikhathi esifanayo, inomphumela othile wokulibazisa. Ixazulula izinkinga zokuqhuma kanye namandla anganele okuqala ngesikhathi senqubo yokwakha, futhi ingandisa isikhathi sokusebenza.

4. I-ejenti ye-interface

Isetshenziswa kakhulu njengesithambisi-ndlela, ingathuthukisa amandla okubamba kanye namandla okucheba, ithuthukise ukwakheka kwendawo, futhi ithuthukise ukunamathela kanye namandla okubopha.

5.Udaka lokuvikela ukushisa lwangaphandle

I-cellulose ether kule nto idlala indima yokubopha nokukhulisa amandla. Isihlabathi sizoba lula ukusimboza, sithuthukise ukusebenza kahle, futhi sibe nomthelela wokungagobeki. Ukusebenza okuphezulu kokugcinwa kwamanzi kungandisa isikhathi sokusebenza kwe-mortar futhi kwandise ukumelana. Ukumelana nokuncipha nokuqhekeka, kuthuthukise ikhwalithi yomphezulu, futhi kwandise amandla okubopha.

6.I-Adhesive yethayela

Ukugcinwa kwamanzi amaningi kuqeda isidingo sokucwilisa noma ukumanzisa amathayili nezisekelo kusengaphambili, okuthuthukisa kakhulu amandla azo okubopha. I-slurry ingakhiwa isikhathi eside, ubuncane, ukufana, ukwakhiwa okulula, kanye nokumelana okuhle nokumanzisa nokufuduka.

1. IthayelaI-Grout,ilungaisigcwalisi

Ukwengezwa kwe-cellulose ether kwenza ibe nokunamathela okuhle komphetho, ukuncibilika okuphansi kanye nokumelana okukhulu kokuguguleka, kuvikela izinto eziyisisekelo ekulimaleni kwemishini, futhi kugwema umthelela wokungena esakhiweni sonke.

8.Izinto ezizilinganisayo

Ukuqina okuzinzile kwe-cellulose ether kuqinisekisa ukugeleza okuhle kanye nekhono lokuzilinganisa, futhi kulawula izinga lokugcina amanzi ukuze kuvunyelwe ukuqina okusheshayo nokunciphisa ukuqhekeka nokuncipha.
