IHydroxypropyl methylcellulose (HPMC) iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo ngochungechunge lwezinqubo zamakhemikhali.Ziyimpushana emhlophe engenaphunga, ayinambitheki futhi engenabuthi ekhukhumala ibe isixazululo se-colloidal esicacile noma esinamafu kancane emanzini abandayo.Inokuqina, ukubopha, ukuhlakaza, ukufaka i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, i-gelling, i-surficial, igcina umswakama kanye nezakhiwo ze-colloid ezivikelayo.I-Hydroxypropyl methyl cellulose kanye ne-methyl cellulose ingasetshenziswa ezintweni zokwakha, imboni kapende, i-resin yokwenziwa, imboni ye-ceramic, imithi, ukudla, izindwangu, ezolimo, amakhemikhali nsuku zonke nezinye izimboni.
Ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose HPMC ezintweni zokwakha:
1. Ukhonkolo osekelwe kusimende
⑴ Thuthukisa ukufana, yenza ukuplasta kube lula ukuphequlula, uthuthukise ukumelana nokuhlehla, uthuthukise uketshezi kanye nokudonsa, futhi uthuthukise ukusebenza kahle komsebenzi.
⑵ Ukugcinwa kwamanzi okuphezulu, ukwandisa isikhathi sokugcina udaka, ukuthuthukisa ukusebenza kahle komsebenzi, nokwenza lula ukugeleza nokuqiniswa kodaka ukuze kukhiqizwe amandla aphezulu emishini.
⑶ Lawula ukwethulwa komoya ukuze ukhiphe imifantu endaweni enamathelayo futhi wenze indawo ekahle ebushelelezi.
2. I-gypsum-based plaster kanye nemikhiqizo ye-gypsum
⑴ Thuthukisa ukufana, yenza ukuplasta kube lula ukuphequlula, uthuthukise ukumelana nokuhlehla, uthuthukise uketshezi kanye nokudonsa, futhi uthuthukise ukusebenza kahle komsebenzi.
⑵ Ukugcinwa kwamanzi okuphezulu, ukwandisa isikhathi sokugcina udaka, ukuthuthukisa ukusebenza kahle komsebenzi, nokwenza lula ukugeleza nokuqiniswa kodaka ukuze kukhiqizwe amandla aphezulu emishini.
⑶ Lawula ukungaguquguquki kodaka ukuze wakhe indawo ekahle enamathelayo.
3. Udaka lwamatshe
⑴ Thuthukisa ukunamathela ngendawo yamatshe, thuthukisa ukugcinwa kwamanzi, futhi uthuthukise amandla odaka.
⑵ Thuthukisa ukuthambisa kanye nepulasitiki, futhi uthuthukise ukwakhiwa;udaka oluthuthukisiwe nge-cellulose ether kulula ukwakha, lusindisa isikhathi sokwakha futhi lunciphisa izindleko zokwakha.
⑶ I-cellulose ether egcina amanzi ephezulu kakhulu, ifanele izitini ezimunca amanzi kakhulu.
4. Isigcwalisi esihlangene sepuleti
⑴Ukugcinwa kwamanzi okuhle kakhulu, nweba isikhathi sokuvula futhi kuthuthukiswe ukusebenza kahle komsebenzi.I-lubricant ephezulu, kulula ukuyixuba.
⑵ Thuthukisa ukumelana nokuncipha kanye nokumelana nokuqhekeka, thuthukisa ikhwalithi yendawo enamathelayo.
⑶ Thuthukisa ukunamathela kwendawo ebophayo futhi unikeze ukuthungwa okubushelelezi nokushelelayo.
5. I-adhesive ye-tile
⑴Kulula ukomisa izithako zemiksi, akukho ukuhlanganisa, khulisa isivinini sohlelo lokusebenza, thuthukisa ukusebenza kokwakha, yonga isikhathi sokusebenza futhi yehlise izindleko zokusebenza.
⑵ Ngokwandisa isikhathi sokuvula, ukusebenza kahle kokuthayela kungathuthukiswa futhi kunganikezwa umphumela omuhle kakhulu wokunamathela.
6. Izinto ezizilinganisa phansi
⑴Nikeza i-viscosity futhi ingasetshenziswa njengesithako esinqanda ukubola.
⑵Thuthukisa ukudonsa kwamanzi futhi uthuthukise ukusebenza kahle kokugandaywa komhlabathi.
⑶ Lawula ukugcinwa kwamanzi kanye nokushwabana, nciphisa imifantu kanye nokushwabana komhlabathi.
7. Upende osuselwe emanzini
⑴Vimbela imvula eqinile futhi welule impilo yesiqukathi somkhiqizo.Ukuzinza okuphezulu kwezinto eziphilayo, ukuhambisana okuhle kakhulu nezinye izakhi.
⑵ Thuthukisa ukugeleza kwamanzi, unikeze izakhiwo ezinhle zokunqanda ukuchaphaza, ezimelene nokusageka kanye nokubeka izinga, futhi uqinisekise ukuqedwa kahle kwendawo.
8. Iphepha lodonga
⑴ Chaza ngokushesha ngaphandle kwezigaxa, ezilungele ukuxutshwa.
⑵ ukunikeza amandla ebhondi ephezulu.
9. Ibhodi likasimende elinwetshiwe
⑴ Inokubambisana okuphezulu kanye nokuthambisa, futhi ithuthukisa ukusebenza kwemikhiqizo ekhishiwe.
⑵ Thuthukisa amandla aluhlaza, ukhuthaze ukugeleza kwamanzi kanye nomphumela wokwelapha, futhi wandise isivuno.
10. Imikhiqizo ye-HPMC yodaka oseluxubile
Umkhiqizo we-HPMC osetshenziselwa ngokukhethekile udaka oluxubekile unokugcinwa kwamanzi okungcono kunemikhiqizo evamile odakeni oluxutshwe kakade, oqinisekisa ukugeleza okwanele kwezinto zikasimende ezingaphili, futhi uvimbele ngokuphawulekayo ukuncishiswa kwamandla ebhondi okubangelwa ukoma nokuqhekeka ngokweqile okubangelwa ukuncipha kokuqina.I-HPMC futhi inomphumela othile wokungenisa umoya.Umkhiqizo we-HPMC osetshenziselwa ngokukhethekile udaka oluxubekile unenani elifanele lamabhamuza omoya afakwe umoya, umfaniswano kanye namabhamuza amancane, angathuthukisa amandla kanye nokushelela kodaka oluxubekile.Umkhiqizo we-HPMC osetshenziselwa ngokukhethekile udaka oluxubekile unomphumela othile wokuvinjelwa, ongandisa isikhathi sokuvulwa kodaka oluxutshwe ngomumo futhi unciphise ubunzima bokwakha.IHydroxypropyl methylcellulose (HPMC) iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo ngochungechunge lwezinqubo zamakhemikhali.Ziyimpushana emhlophe engenaphunga, ayinambitheki futhi engenabuthi ekhukhumala ibe isixazululo se-colloidal esicacile noma esinamafu kancane emanzini abandayo.Inokuqina, ukubopha, ukuhlakaza, ukufaka i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, i-gelling, i-surficial, igcina umswakama kanye nezakhiwo ze-colloid ezivikelayo.I-Hydroxypropyl methyl cellulose kanye ne-methyl cellulose ingasetshenziswa ezintweni zokwakha, imboni kapende, i-resin yokwenziwa, imboni ye-ceramic, imithi, ukudla, izindwangu, ezolimo, amakhemikhali nsuku zonke nezinye izimboni.
