I-Hydroxyethyl methylcellulose (HEMC)iyi-non-ionic cellulose ether esetshenziswa kabanzi ezimbonini eziningi. Iyimpuphu emhlophe noma engeyona emhlophe eyenziwe ngezinto zemvelo ze-polymer - ukotini ocwengekile ngokusebenzisa ukusabela kwamakhemikhali njengokwakheka kwe-alkali kanye ne-ether. Ine-water solubility enhle, ukugcinwa kwamanzi, i-film-forming properties, i-emulsification kanye nokuqina.
1. Isicelo embonini yokwakha
I-Hydroxyethyl methylcellulose isetshenziswa kabanzi embonini yokwakha, ikakhulukazi emikhiqizweni yodaka oluxutshwe okomile, okubonakala kakhulu kulezi zici ezilandelayo:
Ukugcinwa kwamanzi okuqinile: Ngemva kokufaka i-HEMC emikhiqizweni ye-cement mortar noma ye-gypsum, ukusebenza kwayo kokugcinwa kwamanzi kungathuthukiswa kakhulu, kuvimbele ukulahleka kwamanzi ngokweqile, kukhuthaze ukumuncwa kwe-cement, futhi kuthuthukise ukunamathela kanye namandla.
Thuthukisa ukusebenza kokwakha: I-HEMC ingathuthukisa ukugcotshwa nokusebenza kahle kodaka, yenze ukuplasta, ukubeka izitini kanye nezinye izinqubo zibe lula, inciphise ukunamathela kwamathuluzi, futhi ithuthukise ukusebenza kahle kokwakha.
Impahla evimbela ukugoba: Emikhiqizweni yokwakha eqondile njenge-tile adhesive kanye ne-putty powder, i-HEMC ingathuthukisa kakhulu imfanelo yayo yokulwa nokugoba futhi ivimbele izinto ukuthi zingagelezi ngesikhathi sokwakha.
Umphumela wokujiya: I-HEMC ingandisa ukujiya kwe-mortar, okwenza kube lula ukunamathela ebusweni be-substrate, ithuthukise izakhiwo zokumboza kanye ne-slurry.
Thuthukisa isikhathi sokusebenza: Nweba isikhathi sokusebenza, thuthukisa ukuguquguquka kokusebenza, futhi wenze kube lula ukulungisa ukwakhiwa.
Imikhiqizo evamile yokusetshenziswa ifaka: ingcina yethayela, udaka lokuvikela udonga lwangaphandle, i-putty powder, udaka lokuplasta, udaka oluzilinganisayo, udaka oluxubile olomile, njll.
2. Isicelo embonini yokugqoka
Embonini yokugqoka nokupenda, i-hydroxyethyl methyl cellulose isetshenziswa njenge-thickener, i-emulsifier, i-dispersant kanye ne-ejenti yokwakha ifilimu. Imisebenzi yayo imi kanje:
Ukuqina nokuqina: I-HEMC ingakhuphula ngempumelelo ukujiya kopende we-latex, ivimbele ukuna kwemibala, futhi ithuthukise ukuzinza kwesitoreji.
Thuthukisa ukusebenza kokuxubha: Thuthukisa ukusebenza kokuxubha, ukugoqa noma ukufutha kopende, okwenza ukwakheka kwawo kube lula futhi kunciphise ukuchaphaza nokuconsa.
Ukugcinwa kwamanzi kanye nokwakheka kwefilimu: Ukugcina ibhalansi yomswakama ebusweni bepende kusiza ekwakhekeni kwefilimu futhi kuthuthukise ukufana kanye nokushelela kwefilimu yepende.
Ukuzinza okuhle kwe-pH: I-HEMC ingaba khona ngokuzinzile ebangeni elibanzi le-pH (3~11) futhi ifaneleka ezinhlelweni ezahlukene zopende.
Ngakho-ke, i-HEMC isetshenziswa opendeni olusekelwe emanzini njengopende lwe-latex lwangaphakathi nolwangaphandle, upende lwezimboni olusekelwe emanzini, kanye nopende wokhuni.
3. Ukusetshenziswa emikhiqizweni yamakhemikhali yansuku zonke
I-Hydroxyethyl methylcellulose isetshenziswa kabanzi emikhiqizweni yamakhemikhali yansuku zonke njenge-shampoo, i-shower gel, i-toothpaste, kanye nemikhiqizo yokunakekela isikhumba. Imisebenzi yayo eyinhloko yile:
Ukuqina: Thuthukisa ukujiya kwemikhiqizo ewuketshezi futhi uthuthukise ulwazi lomkhiqizo.
Ukuhlanganiswa kwe-emulsification kanye nokumiswa: Ukuqinisa uhlelo lwe-emulsion, vimbela ukuhlukaniswa kwesigaba samafutha kanye nesigaba samanzi, futhi wenze i-paste iqine futhi ifane.
Umphumela wokufumisa: Isebenza kahle ekugcineni amanzi, ivimbela ukuhwamuka kwamanzi esikhumbeni noma ezinweleni, futhi yandisa ukuthambisa.
Ubumnene obuhle: I-HEMC iyi-cellulose engeyona i-ionic engacasuli isikhumba futhi ifanelekela imikhiqizo yesikhumba ebucayi neyengane.
4. Ukusetshenziswa embonini yezemithi kanye nokudla
Nakuba ukusetshenziswa okuyinhloko kwe-HEMC kugxile emkhakheni wezimboni, i-HEMC ingasetshenziswa nasezimbonini zemithi nezokudla ngaphansi kwezidingo ezithile.
Izinto ezisizayo zemithi: I-HEMC isetshenziswa njengento yokubopha, ehlanganisa ifilimu kanye nezinto zokukhulula ezihlala isikhathi eside zamaphilisi ukulawula izinga lokukhululwa kwemithi.
Izithasiselo zokudla: Kwamanye amazwe/izifunda, i-HEMC ivunyelwe ukusetshenziswa njengesithako sokudla, i-emulsifier kanye nesiqinisi, njengasekudleni okuqandisiwe, amaswidi, izinongo, njll.
Izinto zokumboza ezikhishwa njalo: I-HEMC isetshenziselwa ukulungiselela imithi ekhishwa njalo, futhi izakhiwo zayo zokwakha ifilimu zilawula isikhathi sokukhishwa kanye nesilinganiso semithi endleleni yokugaya ukudla.
5. Ukusetshenziswa kwezinye izimboni
Ukubhoboza uwoyela: I-HEMC isetshenziswa njengesinciphisi sokuhlunga kanye nesiqinisi oketshezini lokubhoboza ukuze kuthuthukiswe ukuzinza koketshezi lokubhoboza kanye nokunciphisa ukulahleka koketshezi.
Imboni yokwenza amaphepha: I-HEMC ingasetshenziswa ekuphatheni ubuso bephepha ukuze ithuthukise ukushelela kwayo, ukumelana nowoyela kanye nokunyatheliswa kwayo.
Imboni Yezindwangu: Isetshenziswa njenge-slurry yokunyathelisa nokudaya ukuze inikeze izindwangu ubukhulu obuhle kanye nezakhiwo zokuwasha.
Imboni ye-ceramic: Ngesikhathi senqubo yokwakheka kwe-ceramic, i-HEMC ithuthukisa amandla omzimba oluhlaza futhi ithuthukise ukufana kwe-glazing.
I-Hydroxyethyl methylcelluloseiyi-ether ye-cellulose esebenza ngezindlela eziningi esebenza kahle kakhulu kanye nokusetshenziswa okubanzi. Ukuqina kwayo, ukugcinwa kwamanzi, ukwakha ifilimu, ukuhlanganisa kanye nezinye izakhiwo kuyenza ithathe isikhundla esibalulekile ezimbonini eziningi ezifana nokwakha, ukugqoka, amakhemikhali ansuku zonke, imithi, kanye nokudla. Ngokuthuthuka kokuvikelwa kwemvelo okuluhlaza kanye nemibono yentuthuko esimeme, i-HEMC, njengesithako esinobungani nemvelo esithathwe kwimicu yemvelo, kulindeleke ukuthi iqhubeke nokwandisa isidingo sayo semakethe kanye nezindawo zokusetshenziswa.
