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, i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, i-gelling, indawo esebenzayo, egcina umswakama kanye nezakhiwo ze-colloid ezivikelayo.I-Hydroxypropyl methylcellulose kanye ne-methylcellulose ingasetshenziswa ezintweni zokwakha, imboni kapende, i-resin yokwenziwa, imboni ye-ceramic, imithi, ukudla, izindwangu, ezolimo, amakhemikhali nsuku zonke nezinye izimboni.
Ifomula yekhemikhali:
I-Hydroxypropylmethylcellulose (HPMC)[C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x
Ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose HPMC ezintweni zokwakha:
1. usimende esekelwe ukhonkolo

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 yokunamathela.
3. Udaka lweMasonry
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. I-Panel joint filler
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. Okunamathelayo Kwethayela ⑴Kulula ukomisa izithako zengxube, azikho izigaxa, khulisa isivinini sohlelo lokusebenza, thuthukisa ukusebenza komsebenzi wokwakha, yonga isikhathi sokusebenza futhi yehlise izindleko zokusebenza.⑵ Ngokwandisa isikhathi sokuvula, ukusebenza kahle kokuthayela kungathuthukiswa futhi kunganikezwa umphumela omuhle kakhulu wokunamathela.
6. Izinto ezisebenza phansi ezizilinganisa ⑴ zinikeza i-viscosity futhi zingasetshenziswa njengezithasiselo zokunqanda 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. Impushana yangemuva ⑴ Chaza ngokushesha ngaphandle kwezigaxa, ezilungele ukuxutshwa.⑵ ukunikeza amandla ebhondi ephezulu.
9. Ibhodi likasimende elaluliwe (1) linokubambisana okuphezulu kanye nokuthambisa, futhi lithuthukisa ukusebenza kahle kwemikhiqizo ekhishiwe.⑵ Thuthukisa amandla aluhlaza, ukhuthaze ukugeleza kwamanzi kanye nomphumela wokwelapha, futhi wandise isivuno.
10. Imikhiqizo ye-HPMC enikezelwe odakeni oluxubile lwemikhiqizo ye-HPMC enikezelwe odakeni oluxubekile inokugcinwa kwamanzi kangcono odakeni oluxutshwe ngodaka kunemikhiqizo evamile, iqinisekisa ukugeleza okwanele kwezinto zikasimende ezingaphili, okuvimbela kakhulu ukuncishiswa kwamandla ebhondi okubangwa ukomiswa ngokweqile. , kanye Nemifantu ebangelwa ukushwabana komiswe.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 oluxubile.Umkhiqizo we-HPMC osetshenziselwa ngokukhethekile udaka oluxubekile unomphumela othile wokuvinjelwa, ongandisa isikhathi sokuvulwa kodaka oluxubile futhi unciphise ubunzima bokwakha.
