Imikhiqizo yodaka lwe-Dry-mix yemboni yezokwakha ithuthuke kakhulu ngokuhamba kweminyaka.Le mikhiqizo isidume ngokusebenziseka kwayo, ukuguquguquka, kanye nokusebenziseka kalula.Inqubekelaphambili ebalulekile emikhiqizweni yodaka eyomile ukusetshenziswa kwe-hydroxypropylmethylcellulose (HPMC) kanye ne-methylhydroxyethylcellulose (MHEC).Lawa ma-cellulose ethers asetshenziswa kakhulu ekukhiqizeni udaka oluxutshwe okomile futhi ahlinzeke abasebenzisi ngezinzuzo eziningi.Kulesi sihloko, sixoxa ngezinzuzo ze-HPMC kanye ne-MHEC emikhiqizweni yodaka olomile.
1. Ukugcinwa kwamanzi
Enye yezinzuzo eziphawuleka kakhulu ze-HPMC kanye ne-MHEC emikhiqizweni yodaka oluxutshwe okomile ukugcinwa kwamanzi.Lawa ma-cellulose ether angabamba amanzi amaningi futhi awavimbele ukuthi ahwamuke ngokushesha.Lokhu kubalulekile kuma-dry-mix mortars, adinga ukufakwa kwamanzi njalo ukuze kusebenze kahle.I-HPMC ne-MHEC basebenza ngokwenza ifilimu elincanyana elizungeze izinhlayiya zodaka, elibambezela ukuhwamuka kwamanzi.Ngenxa yalokho, udaka luhlala lusetshenziswa isikhathi eside, lunciphisa ithuba lokuqhekeka futhi luthuthukise isibopho.
2. Thuthukisa ukunamathela
Imikhiqizo yodaka oluxutshwe okomile esebenzisa i-HPMC ne-MHEC inokunamathela okungcono kunemikhiqizo yodaka oluxutshwe okomile ngaphandle kwe-cellulose ether.I-HPMC kanye ne-MHEC banezakhiwo ezinhle kakhulu zokunamathela, eziqinisekisa ukuthi udaka lunamathela ku-substrate futhi luhlala endaweni.Futhi anokwakheka okunamathelayo okufana nepulasitiki okujiya udaka futhi kwenze kube lula ukuwufaka.Lezi zakhiwo zenza i-HPMC ne-MHEC zilungele izinhlelo zokusebenza ezima mpo lapho amandla adonsela phansi adonsela udaka odongeni.
3. Ukuqina okwenyuka
I-HPMC kanye ne-MHEC emikhiqizweni yodaka exutshwe okomile iphinde ithuthukise ukuqina komkhiqizo wokugcina.Ama-cellulose ether asebenzisana nosimende nezinye izithako ukuze akhe izakhiwo ezizinzile neziqinile.Udaka olukhiqizwayo alujwayele ukuqhekeka, ukushwabana nezinye izinhlobo zokuwohloka.Ukwengeza, i-HPMC kanye ne-MHEC benza udaka lumelane namanzi nezinye izakhi, okuqinisekisa impilo yaso yesevisi ende.
4. Thuthukisa ukusebenza
Imikhiqizo yodaka oluxutshwe okomile equkethe i-HPMC ne-MHEC inokusebenziseka okuhle kakhulu nokuvumelana nezimo.Ukusebenza kahle kwalawa ma-cellulose ethers kusho ukuthi ama-mortars kulula ukuwaxuba, ukuwafaka futhi abushelelezi.Ziphinde zinikeze ukuguquguquka okuhle kakhulu, okuvumela udaka ukuthi lwande futhi lunciphe ngaphandle kokuqhekeka noma ukulahlekelwa ubuqotho balo besakhiwo.Lokhu kuvumelana nezimo kuwusizo ikakhulukazi ezindaweni lapho izinto zokwakha zichayeka ekushintshashintsheni kwezinga lokushisa noma ezinye izinhlobo zokucindezeleka.
5. Ukwakheka Okuthuthukisiwe
Uma yengezwe odakeni lwengxube eyomile, i-HPMC ne-MHEC zinikeza izici zombhalo ezihlukile.Ama-cellulose ether adala ukuthungwa okubushelelezi, okukhilimu okuthuthukisa ubuhle bodaka.Lokhu kuthungwa kwenza udaka lusebenze kalula ngoba ngeke lugoqe noma lugoqe.Ukuze ukubonakala komkhiqizo wodaka ophelile ohlangene omile ufana futhi muhle.
6. Kulula ukufaka isicelo
Enye inzuzo ye-HPMC ne-MHEC emikhiqizweni yodaka oluxutshwe okomile kulula ukuyisebenzisa.Lawa ma-cellulose ethers kulula ukuwaxuba futhi asetshenziswe futhi awadingi ulwazi olukhethekile ongawasebenzisa.Osonkontileka bangafaka udaka besebenzisa izindlela zendabuko ezifana namabhulashi, amarola, amatrowel noma izibhamu zokufutha.Lokhu kwenza udaka lwemiksi eyomile equkethe i-HPMC ne-MHEC kube ukukhetha okuhle kakhulu kubakhi abangochwepheshe kanye nama-DIYers ngokufanayo.
7. Ukusebenza kahle kwezindleko
Imikhiqizo yodaka lwe-dry-mix equkethe i-HPMC ne-MHEC nayo iyonga kakhulu.Lawa ma-cellulose ethers ayathengeka futhi adinga inani elincane kuphela ukufeza umphumela oyifunayo.Ukwengeza, i-HPMC ne-MHEC zivumela udoti omncane, njengoba udaka luhlala lunamanzi isikhathi eside.Ngenxa yalokho, sincane isidingo sokusebenza kabusha noma ukulungiswa, kunciphisa izindleko zezinto ezibonakalayo.
Ukusetshenziswa kwe-HPMC kanye ne-MHEC emikhiqizweni yodaka oluxubile kunikeza izinzuzo eziningi embonini yezokwakha.Lawa ma-cellulose ethers athuthukisa ukugcinwa kwamanzi, ukunamathela, ukuqina, ukucutshungulwa, ukuthungwa kanye nokusebenziseka kalula.Ngaphezu kwalokho, ayabiza, okuwenza abe inketho ekhangayo kubakhi nabanikazi bezindlu.Ngakho-ke, ukwamukelwa kwalawa ma-cellulose ethers ekukhiqizeni udaka lwengxube eyomile kungenzeka kuqhubeke ukukhula eminyakeni ezayo njengoba abakhi befuna ukwakha izakhiwo ezihlala isikhathi eside nezithembekile.
