Izinzuzo ze-HPMC&MHEC emikhiqizweni yodaka olomile oluxubile

Isingeniso ku-HPMC kanye ne-MHEC:

I-HPMC kanye ne-MHEC ama-cellulose ether avame ukusetshenziswa ezintweni zokwakha, okuhlanganisa udaka lwemiksi eyomile. Lawa ma-polymers asuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Uma yengezwe osikeni lwengxube eyomile, i-HPMC ne-MHEC zisebenza njengama-thieners, ama-ejenti okugcina amanzi, ama-binders, futhi zithuthukisa ukusebenza kanye nezakhiwo zokubopha.

1. Ukugcinwa kwamanzi:

I-HPMC kanye ne-MHEC ama-polymers angama-hydrophilic, okusho ukuthi anobudlelwane obuphezulu bamanzi. Uma ihlanganiswa emigodini exubene neyomile, yenza ifilimu encane ebusweni bezinhlayiya zikasimende, ivimbele ukuhwamuka kwamanzi ngokushesha ngesikhathi sokuphulukiswa. Le hydration ehlala isikhathi eside ithuthukisa ukuthuthukiswa kwamandla odaka, inciphisa ingozi yokuqhekeka futhi iqinisekise ukusetha okulungile.

2. Thuthukisa ukusebenza:

I-HPMC kanye ne-MHEC bathuthukisa ukusebenza kodaka lwengxube eyomile ngokunikeza ukuthambisa. Asebenza njengama-plasticizer, anciphisa ukungqubuzana phakathi kwezinhlayiya futhi enze udaka lube lula ukuxutshwa, ukusabalalisa nokuqeda. Lokhu kusebenza okuthuthukisiwe kubangela ukungaguquguquki okungcono kanye nokufana kongqimba lukadaka olusetshenzisiwe.

3. Khulisa amahora okuvula:

Isikhathi sokuvula isikhathi lapho udaka luhlala lusetshenziswa ngemva kokuxuba. I-HPMC kanye ne-MHEC banweba isikhathi esivulekile sodaka lwengxube eyomile ngokunciphisa izinga lokuhwamuka kwamanzi. Lesi sici sizuzisa kakhulu kumaphrojekthi wokwakha amakhudlwana adinga izikhathi ezinwetshiwe zokusebenza, ezifana nokufaka amathayela noma ukhonkolo.

4. Thuthukisa ukunamathela:

Ukuba khona kwe-HPMC kanye ne-MHEC ku-dry mix mortars kukhuthaza ukunamathela okungcono ezinhlobonhlobo zama-substrates ahlanganisa ukhonkolo, ama-masonry namathayili e-ceramic. Lawa ma-polymer adala ukubumbana phakathi kodaka ne-substrate, athuthukisa ukuqina nokusebenza kwezinto ezisetshenzisiwe. Ukwengeza, banciphisa ingozi ye-delamination kanye nokwehlukana ngokuhamba kwesikhathi.

5. Ukumelana nokuqhekeka:

Ukuqhekeka kuyinkinga evamile ngodaka, ikakhulukazi phakathi nezigaba zokomisa nokuphulukisa. I-HPMC ne-MHEC zisiza ukunciphisa le nkinga ngokuthuthukisa ukuhlangana nokuguquguquka kwe-matrix yodaka. Ngokunciphisa ukushwabana nokulawula inqubo ye-hydration, lawa ma-polymers asiza ukuthuthukisa ukumelana nokuqhekeka okuphelele kodaka oluqediwe, okuholela esakhiweni esihlala isikhathi eside.

6. Ukuhlukahluka:

I-HPMC kanye ne-MHEC ziyizithasiselo ezihlukahlukene ezingasetshenziswa ezinhlobonhlobo zokwakheka kodaka lwengxube eyomile. Kungakhathaliseki ukuthi ama-masonry mortars, izinto zokunamathisela zamathayela, izinhlanganisela ezizilinganisa noma izinsimbi zokulungisa, lawa ma-polymers ahlinzeka ngokusebenza okungaguquki nokuhambisana nezinye izithako. Lokhu kuhlukahluka kwenza inqubo yokukhiqiza ibe lula futhi kuvumela ukuthuthukiswa kwezixazululo zodaka lwangokwezifiso zezinhlelo zokusebenza ezithile.

7. Izinzuzo zemvelo:

I-HPMC kanye ne-MHEC izithasiselo ezinobungani kwemvelo ezithathwe kuzinsiza ezivuselelekayo. Ukusetshenziswa kwazo ezidakamizweni ezixubene ezomile kusiza ukunciphisa ukusetshenziswa kwemithombo yemvelo futhi kunciphise ukuphehlwa kwemfucuza, ngaleyo ndlela kukhuthaze intuthuko esimeme. Ukwengeza, ukubola kwawo kwemvelo kuqinisekisa umthelela omncane wemvelo ekupheleni komjikelezo wokuphila kodaka.

I-HPMC ne-MHEC zinezinzuzo eziningi nezibalulekile emikhiqizweni yodaka exutshwe okomile. Kusukela ekuthuthukiseni ukusebenza kahle nokunamathela kuye ekuthuthukiseni ukumelana nokuqhekeka nokuqina, lawa ma-cellulose ether adlala indima ebalulekile ekuthuthukiseni ukusebenza nokuhlala isikhathi eside kwezinsimbi ezisetshenziswayo zokwakha. Njengezithasiselo ezisimeme neziguquguqukayo, i-HPMC kanye ne-MHEC kuseyisinqumo sokuqala sabakhiqizi abafuna ukuthuthukisa ukusebenza kokwakhiwa kodaka lwabo kuyilapho benciphisa umthelela wemvelo.
