I-HEMC yezinga lokwakha

I-HEMC yezinga lokwakhaI-HydroxyethylMi-ethylCi-elliloseyaziwa ngokuthi i-Methyl Hydroxyethyl Cellulose (MHEC), yonakuyimpuphu emhlophe noma engemhlophe kangako, ayinaphunga futhi ayinambitheki, iyancibilikaKokubili emanzini ashisayo namanzi abandayo. I-HEMC yezinga lokwakha ingabaIsetshenziswa njenge-samente, i-gypsum, i-lime gelling agent, i-ejenti yokugcina amanzi, iyinhlanganisela enhle kakhulu yezinto zokwakha zempuphu.

Isakhiwo sama-molecule:

Izici Zomkhiqizo:

1. Ukubukeka: I-HEMC iyimpuphu emhlophe noma cishe emhlophe; ayinaphunga futhi ayinambitheki.

2. Ukuncibilika: Uhlobo lwe-H ku-HEMC lungancibilika emanzini angaphansi kuka-60℃, kanti uhlobo lwe-L lungancibilika kuphela emanzini abandayo. I-HEMC iyafana ne-HPMC futhi ayincibiliki ezincibilikisini eziningi eziphilayo. Ngemva kokwelashwa kobuso, i-HEMC ihlakazeka emanzini abandayo ngaphandle kokuhlangana futhi incibilike kancane, kodwa ingancibilika ngokushesha ngokulungisa inani layo le-PH libe ngu-8-10.

3. Ukuqina kwenani le-PH: I-viscosity ayishintshi kakhulu ngaphakathi kwebanga eliphakathi kuka-2-12, futhi i-viscosity yonakala ngale kwaleli banga.

4. Ubuncane: izinga lokuphasa elingama-mesh angu-80 lingu-100%; izinga lokuphasa elingama-mesh angu-100 lingu-≥99.5%.

5. Amandla adonsela phansi angamanga: 0.27-0.60g/cm3.

6. Izinga lokushisa lokubola lingaphezu kuka-200℃, futhi liqala ukusha ku-360℃.

7. I-HEMC inokuqina okukhulu, ukuqina kokumiswa, ukuhlakazeka, ukuhlangana, ukubumbeka, ukugcinwa kwamanzi nezinye izici.

8. Ngenxa yokuthi umkhiqizo uqukethe iqembu le-hydroxyethyl, izinga lokushisa lejeli lomkhiqizo lifinyelela ku-60-90℃. Ngaphezu kwalokho, iqembu le-hydroxyethyl linokuphiliswa okuphezulu kwamanzi, okwenza futhi izinga lokubopha lomkhiqizo libe lihle. Ikakhulukazi ekwakhiweni kokushisa okushisayo nokushisa okuphezulu ehlobo, i-HEMC inokugcinwa kwamanzi okuphezulu kune-methyl cellulose ene-viscosity efanayo, futhi izinga lokugcina amanzi alingaphansi kuka-85%.

Ibanga Lemikhiqizo

Ukubaluleka

Njenge-ejenti esebenzayo ebusweni, i-hydroxyethyl methyl cellulose HEMC inezici ezilandelayo ngaphezu kokuqina, ukumiswa, ukubopha, ukuhlanganisa, ukwakha ifilimu, ukusabalalisa, ukugcina amanzi kanye nokunikeza ama-colloids avikelayo:

(1) I-Hydroxyethyl methyl cellulose HEMC iyancibilika emanzini ashisayo noma abandayo, okwenza ibe nezici eziningi zokuncibilika kanye ne-viscosity, okungukuthi, i-gelation engashisi;

(2) I-Hydroxyethyl methyl cellulose HEMC ingasebenza ndawonye nezinye izinhlobo eziningi zama-polymer ancibilikayo emanzini, ama-surfactants, kanye nosawoti, futhi iyisithako esihle kakhulu sezixazululo ze-electrolyte ezigxile kakhulu;

(3) I-HEMC inokugcinwa kwamanzi okuqinile kune-methyl cellulose, futhi ukuqina kwayo kwe-viscosity, ukuhlakazeka, kanye nokumelana kwayo nesikhunta kunamandla kunokwe-hydroxyethyl cellulose.

Indlela yokulungiselela isixazululo

(1) Engeza inani elithile lamanzi ahlanzekile esitsheni;

(2) Faka i-hydroxyethyl methyl cellulose HEMC ngaphansi kokuxuba ngesivinini esiphansi, bese uvuselela kuze kube yilapho yonke i-hydroxyethyl methyl cellulose incibilika ngokulinganayo;

(3) Ngenxa yedatha yethu yokuhlolwa kobuchwepheshe, kunconywa kakhulu ukuthi uyifake ngemva kokufakwa kwe-polymer emulsion (okungukuthi, i-hydroxyethyl methyl cellulose).I-HEMCixutshwe kusengaphambili ne-ethylene glycol noma i-propylene glycol).

Usubudala

Kwezimboniisakhiwoizinto zokwakha,izinga lokwakha i-HEMCkufanelekileingcina yethayela, amaplasta esimende, udaka oluxubile olomile, ukuzilinganisa, iplasta ye-gypsum,upende we-latex, izihlanganisi zezinto zokwakha, ezinye izinkambu zokwakha, ukubhoboza izindawo zikawoyela, imikhiqizo yokunakekela umuntu siqu, izinto zokuhlanza, njll., ezivame ukusetshenziswa njengezithambisi, izinto zokuvikela, izinamathiseli, izinto zokuqinisa, kanye nezinto zokubopha, zingasetshenziswa futhi njengamajeli athanda amanzi, izinto ze-matrix, ukulungiselela amalungiselelo okukhululwa okuqhubekayo kohlobo lwe-matrix, futhi zingasetshenziswa njengezithambisi ekudleni, njll. umphumela.

Pukugoqa kanye nesitoreji

(1) Ipakishwe esikhwameni se-polyethylene esihlanganisiwe sephepha noma esikhwameni sephepha, esingama-25KG/isikhwama;

(2) Gcina umoya ugeleza endaweni yokugcina izinto, gwema ukukhanya kwelanga okuqondile, futhi ugcine kude nemithombo yomlilo;

(3) Ngenxa yokuthi i-hydroxyethyl methyl cellulose HEMC i-hygroscopic, akufanele ivezwe emoyeni. Imikhiqizo engasetshenziswanga kufanele ivalwe futhi igcinwe, futhi ivikelwe emswakama.
