I-HPMC – Isengezo se-Dry mix mortar

ethula:

Izinsimbi zokuxuba ezomile zithandwa embonini yezokwakha ngenxa yokusebenziseka kalula, izinga elithuthukisiwe kanye nokusebenza kahle kwesikhathi.Izithasiselo ezihlukahlukene zidlala indima ebalulekile ekuthuthukiseni ukusebenza kodaka lwengxube eyomile, futhi esinye sezithasiselo ezaziwa kakhulu yi-hydroxypropyl methylcellulose (HPMC).Le polymer eguquguqukayo isetshenziswa kabanzi odakeni lwengxube eyomile ukusiza ukuthuthukisa ukusebenza, ukunamathela kanye nokusebenza kodaka jikelele.

Isakhiwo samakhemikhali kanye nezakhiwo ze-HPMC:

IHydroxypropylmethylcellulose iphuma ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Isakhiwo samakhemikhali se-HPMC sibonakala ngokuba khona kwamaqembu e-hydroxypropyl kanye ne-methyl kumgogodla we-cellulose.Lesi sakhiwo esiyingqayizivele sinikeza izakhiwo ezithile ze-HPMC, okuyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene embonini yezokwakha.

Izici ezibalulekile ze-HPMC zifaka:

Ukugcinwa kwamanzi:

I-HPMC inomthamo omuhle kakhulu wokugcina amanzi, iqinisekisa ukuthi udaka luhlala lusetshenziswa isikhathi eside.Lesi sakhiwo sibalulekile ukuvimbela udaka ukuthi lome ngaphambi kwesikhathi futhi luvumela ukusetshenziswa okungcono ezindaweni ezihlukene.

Ikhono lokujiya:

I-HPMC isebenza njengokuqina futhi isiza ukuthuthukisa ukungaguquguquki nokusebenza kodaka.Lokhu kuzuzisa kakhulu ekusetshenzisweni okuqondile lapho udaka ludinga ukunamathela phezulu ngaphandle kokuhlehla.

Thuthukisa ukunamathela:

Ukuba khona kwe-HPMC kuthuthukisa ukunamathela kodaka kuma-substrates ahlukahlukene, kukhuthaze ukubopha okungcono nokuqina kwesakhiwo sokugcina. 

Setha ukulawula isikhathi:

Ngokulungisa ngokucophelela uhlobo nenani le-HPMC ku-recipe yodaka lwengxube eyomile, isikhathi sokusetha sodaka singalawulwa.Lokhu kuvumela amaphrojekthi wokwakha ukuthi aguquguquke futhi avumelane nezimfuneko ezahlukahlukene nezimo zemvelo.

Ukuvumelana nezimo nokumelana nokuqhekeka:

I-HPMC inika ukuguquguquka kodaka, inciphisa amathuba okuqhekeka kanye nokwenza ngcono ukuqina kukonke.Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho isakhiwo singaphansi kwamandla aguquguqukayo noma izinguquko zezinga lokushisa.

Ukusetshenziswa kwe-HPMC odakeni olomile oluxubile :

I-adhesive yethayela:

I-HPMC ijwayele ukusetshenziswa kuma-adhesives wethayela ukuthuthukisa ukunamathela, ukugcinwa kwamanzi nokusebenza.I-polymer iqinisekisa isibopho esiqinile phakathi kwe-tile ne-substrate, ngaleyo ndlela ikhulise isikhathi eside se-tile surface.

Udaka lokunamathisela:

Emasikeni okuplasta, i-HPMC isiza ukuthuthukisa ukusebenza nokunamathela kwengxube.I-polymer isiza ukufeza indawo ye-plaster ebushelelezi futhi engaguquki ngenkathi inciphisa ubungozi bokuqhekeka.

Udaka lwamatshe:

I-HPMC isetshenziswa odakeni lwamatshe ukuze kuthuthukiswe ukugcinwa kwamanzi, ukusebenza kahle nokunamathela.Izakhiwo ezithuthukisiwe zokubopha zenza izakhiwo zamatshe zibe namandla futhi zihlale isikhathi eside.

Izinhlanganisela zokuzilinganisa:

Izakhiwo ezigcina amanzi kanye nokujiya ze-HPMC ziyenza ifanelekele ukusetshenziswa kuzinhlanganisela ezizilinganisa.Lezi zinhlanganisela ziqinisekisa ubuso obushelelezi futhi zingasetshenziswa ezimweni ezihlukahlukene zokwakha.

Isigcwalisi se-Seam:

I-HPMC ifakwe ku-caulk ukuthuthukisa ukuguquguquka nokunamathela.Lokhu kubaluleke kakhulu kumalunga ahambayo kanye nokwanda kokushisa.

Ukulawula Ikhwalithi Nokuhambisana:

Ukuqinisekisa ikhwalithi nokuhambisana kwe-HPMC odakeni lwengxube eyomile kubalulekile ukuze kuzuzwe ukusebenza okudingekayo.Izinyathelo zokulawula ikhwalithi zihlanganisa ama-polymer okuhlola amapharamitha afana ne-viscosity, okuqukethwe komswakama nokusabalalisa usayizi wezinhlayiyana.Izifundo zokuhambisana kufanele zenziwe ukuze kuhlolwe ukusebenzisana phakathi kwe-HPMC nezinye izithako ekwakhiweni kodaka ukuze kuqinisekiswe imiphumela ye-synergistic ngaphandle kokusabela okubi.

Ukucatshangelwa kwemvelo:

I-HPMC ithathwa njengenobungani nemvelo njengoba isuselwa ezinsizeni ezivuselelekayo.I-biodegradability ye-HPMC iqinisekisa ukuthi ukusetshenziswa kwayo ezinhlelweni zokwakha ngeke kube nomthelela wesikhathi eside endaweni ezungezile.

Ekuphetheni:

IHydroxypropyl methylcellulose iyisengezo esisebenza ngezindlela eziningi futhi esiwusizo endaweni yodaka lwengxube eyomile.Inhlanganisela yayo eyingqayizivele yezakhiwo, okuhlanganisa ukugcinwa kwamanzi, amandla okuqina nokunamathela okuthuthukisiwe, kuyenza ibe isithako esiyinhloko emisebenzini ehlukahlukene yokwakha.Njengoba imboni yezokwakha iqhubeka nokuthuthuka, indima ye-HPMC ekwenzeni ngcono ukusebenza kanye nokuzinza kwezinsimbi zengxube eyomile ingase ikhule, ngaleyo ndlela ibe nomthelela ezenzweni zokwakha ezisebenza kahle nezihlala isikhathi eside.
