01.I-Hydroxyethyl Cellulose
Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose ayinayo kuphela imisebenzi yokumisa, ukuqina, ukuhlakaza, ukuntanta, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi nokuhlinzeka nge-colloid evikelayo, kodwa futhi inezindawo ezilandelayo:
1. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ngokushisa okuphezulu noma ukubila, ukuze ibe nezici eziningi zokuncibilika kanye nezici ze-viscosity, kanye ne-gelation engashisi;
2. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa i-colloid evikelayo inamandla amakhulu.
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
Izinyathelo zokuqapha lapho usebenzisa:
Njengoba i-hydroxyethyl cellulose ehlanjululwe phezulu iyimpushana noma i-cellulose eqinile, kulula ukuyiphatha futhi incibilike emanzini inqobo nje uma lezi zindaba ezilandelayo ziphawulwa.
1. Ngaphambi nangemva kokwengeza i-hydroxyethyl cellulose, kufanele iqhubeke inyakaziswa kuze kube yilapho isisombululo sisobala ngokuphelele futhi sicacile.
2. Kumele ihlungwe emgqonyeni wokuxuba kancane. Ungafaki ngokuqondile i-hydroxyethyl cellulose eyakheke yaba izigaxa noma amabhola emgqonyeni wokuxuba ngobuningi noma ngokuqondile.
3. Izinga lokushisa lamanzi kanye nenani le-pH lamanzi linobudlelwano obubalulekile nokuqedwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kuqashelwe ngokukhethekile.
4. Ungalokothi wengeze ezinye izinto ezine-alkali engxubeni ngaphambi kwei-hydroxyethyl celluloseimpushana ifudunyezwa ngamanzi. Ukuphakamisa inani elingu-PH ngemva kokufudumala kuyasiza ekuhlakazweni.
Ukusetshenziswa kwe-HEC:
1. Ngokuvamile isetshenziswa njenge-ejenti yokuqina, i-ejenti evikelayo, i-adhesive, stabilizer kanye nesengezo sokulungiselela i-emulsion, ijeli, amafutha okugcoba, i-lotion, i-ejenti yokuhlanza amehlo, i-suppository kanye nethebhulethi, ebuye isetshenziswe njengejeli le-hydrophilic, izinto zamathambo, ukulungiswa kwama-skeleton amalungiselelo okukhululwa okuqhubekayo, kanye ne-stabilizer ekudleni.
2. Isetshenziswa njenge-ejenti yokulinganisa embonini yendwangu, i-bonding, ukuqina, i-emulsifying, i-stabilizing nezinye izinsiza emikhakheni ye-electronics kanye nemboni yokukhanya.
3. Isetshenziswa njengesinciphisi esijiya nesihluza oketshezini lokumba olusekelwe emanzini kanye noketshezi oluqedayo, futhi inomphumela osobala wokujiya oketshezini lokumba amanzi anosawoti. Ingasetshenziswa futhi njenge-ejenti yokulawula ukulahlekelwa okuwuketshezi kasimende womthombo wamafutha. Ingaxhunyaniswa ne-polyvalent metal ions ukwenza ama-gel.
5. Lo mkhiqizo usetshenziswa njenge-disperant ku-gel-based fracturing fluids, i-polystyrene ne-polyvinyl chloride ekukhiqizeni i-oyela fracturing. Ingasetshenziswa futhi njenge-emulsion thickener embonini kapende, i-resistor ebucayi yomswakama embonini ye-elekthronikhi, i-cement coagulation inhibitor kanye ne-ejenti yokugcina umswakama embonini yezokwakha. I-glazing kanye ne-toothpaste adhesives embonini ye-ceramic. Ibuye isetshenziswe kabanzi ekunyatheliseni nasekudayeni, izindwangu, ukwenza amaphepha, imithi, inhlanzeko, ukudla, ugwayi, izibulala-zinambuzane kanye nezinto ezicisha umlilo.
02.Hydroxypropyl Methyl Cellulose
1. Imboni yokumboza: Njenge-thickener, dispersant kanye ne-stabilizer embonini yokugqoka, inokuhambisana okuhle emanzini noma ku-organic solvents. njengesikhiphi sikapende.
2. Ukwenziwa kwe-Ceramic: isetshenziswa kabanzi njengesibophezelo ekwenzeni imikhiqizo yobumba.
3. Abanye: Lo mkhiqizo futhi usetshenziswa kabanzi embonini yesikhumba, yemikhiqizo yephepha, ukulondolozwa kwezithelo nemifino kanye nemboni yendwangu, njll.
4. Ukuphrinta kukayinki: njenge-thickener, dispersant kanye ne-stabilizer embonini ye-inki, inokuhambisana okuhle emanzini noma ku-organic solvents.
5. Ipulasitiki: isetshenziswa njenge-ejenti yokukhululwa yokubumba, isithambile, isithambiso, njll.
6. I-Polyvinyl chloride: Isetshenziswa njenge-disperant ekukhiqizeni i-polyvinyl chloride, futhi iyi-ejenti eyinhloko eyisizayo yokulungiswa kwe-PVC ngokumiswa kwe-polymerization.
7. Imboni yezokwakha: Njenge-ejenti egcina amanzi kanye ne-retarder kudaka lukasimende, udaka luyakwazi ukudonsa. Isetshenziswa njenge-binder ku-plasterpaste, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwelula isikhathi sokusebenza. Isetshenziswa njenge-paste ye-ceramic tile, imabula, umhlobiso wepulasitiki, njengesithuthukisi sokunamathisela, futhi inganciphisa inani likasimende. Ukugcinwa kwamanzi kwe-hydroxypropyl methylcelluloseI-HPMCingavimbela i-slurry ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi ithuthukise amandla ngemva kokuqina.
8. Imboni yezemithi: izinto zokugqoka; izinto zefilimu; izinto zokwakha ze-polymer ezilawula isilinganiso sokulungiselela ukukhishwa okuqhubekayo; izinza; ama-agent amisiwe; izibophezelo zethebhulethi; ama-tackifiers.
Imvelo:
1. Ukubukeka: impushana emhlophe noma emhlophe.
2. Usayizi wezinhlayiya; Izinga lokuphasa elingu-100 likhulu kuno-98.5%; Izinga lokuphasa nge-80 mesh ngu-100%. Usayizi wezinhlayiyana zokucaciswa okukhethekile yi-40 ~ 60 mesh.

7. Ukuncibilika: kuncibilika emanzini nakwezinye izincibilikisi, njengengxenye efanele ye-ethanol/amanzi, i-propanol/amanzi, njll. Izixazululo ezinamanzi ziyasebenza phezulu. Ukucaca okuphezulu nokusebenza okuzinzile. Ukucaciswa okuhlukile kwemikhiqizo kunamazinga okushisa e-gel ahlukene, futhi izinguquko zokuncibilika nge-viscosity. I-viscosity ephansi, i-solubility enkulu. Ukucaciswa okuhlukile kwe-HPMC kunezindawo ezihlukile. Ukuhlakazwa kwe-HPMC emanzini akuthintwa inani le-pH.
8. Ngokuncipha kokuqukethwe kweqembu le-methoxy, iphuzu lejeli liyakhula, ukuncibilika kwamanzi kuncipha, futhi umsebenzi ongaphezulu we-HPMC uyancipha.
9. I-HPMCfuthi inezici zekhono lokuqina, ukumelana nosawoti, impushana yomlotha ephansi, ukuzinza kwe-pH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, izakhiwo ezinhle kakhulu zokwakha ifilimu, kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokuhlangana.
