Njengezinto ezibalulekile emisebenzini yokwakha, ukusebenza kukaMasonzi kuthinta ngqo ikhwalithi nokuqina kwesakhiwo. Ku-masonry udaka, ukugcinwa kwamanzi kungenye yezinkomba ezibalulekile ezinquma ukusebenza kwayo namandla okugcina. I-Hydroxypropyll methyl cellulose (HPMC, i-Hydroxypropyl methyl celtuleose) isengezo esisetshenziswa kakhulu esisetshenziselwa ukuthuthukisa ukugcinwa kwamanzi ngodaka lwamanzi.
1. Isakhiwo samangqamuzana se-HPMC
I-HPMC iyi-ether ye-cellulose engeyona eye-ionic, futhi isakhiwo sayo samangqamuzana sinomthelela omkhulu ekusebenzeni kokugcinwa kwamanzi kodaka. Isisindo samangqamuzana kanye nezinga lokufaka esikhundleni (kufaka phakathi izinga lokufaka esikhundleni se-methoxy ne-hydroxypropopoxy amaqembu) ye-HPMC inqume i-solubity yayo yamanzi namandla okubamba amanzi. Izinsimbi eziphakeme zamangqamuzana kanye neziqu ezilinganiselwe zokufakwa esikhundleni ngokuvamile zithuthukisa izakhiwo zokugcinwa kwamanzi zodonga ngoba ziyakwazi ukwakha uhlelo oluzinzile lwe-colloidal ku-datar futhi unciphise ukuhwamuka kwamanzi nokungena kwamanzi.
2. Ukungeza inani le-HPMC
Inani le-HPMC elingeziwe liyisici esiqondile esithinta ukugcinwa kwamanzi kodaka. Inani elifanele le-HPMC lingathuthukisa kakhulu amandla okugcina amanzi oDinga, ukuvumela ukuthi kugcinwe ukusebenza okuhle kokusebenza ngaphansi kwezimo ezomile. Kodwa-ke, amanani amaningi we-HPMC angadala ukuthi udaka abe seluhle kakhulu, wandise ubunzima bokwakha, futhi anciphise amandla. Ngakho-ke, kuzinhlelo zokusebenza ezisebenzayo, inani lokungezwa le-HPMC lidinga ukulawulwa ngokunembile ngokuya ngezidingo ezithile zokwakha kanye nezimo zemvelo.
I-3. Ukwakheka kanye nengxenye yodaka
Ukwakheka kanye nengxenye yodaka kuthinta kakhulu umphumela wokugcina amanzi we-HPMC. Izithako zodaka ezisetshenziswayo ezisetshenziswayo zifaka usimende, lime, i-aggregate enhle (isihlabathi) namanzi. Izinhlobo ezahlukahlukene kanye nezilinganiso zikasimende kanye nokuhlanganiswa okuhle kuzothinta ukuhanjiswa kwezinhlayiyana kanye nokwakheka komgogodla wodaka, ngaleyo ndlela kuguqula ukusebenza kwe-HPMC. Isibonelo, isihlabathi esihle kanye nenani elifanele lezinhlawulo kunganikeza indawo engaphezulu komhlaba, ukusiza i-HPMC ukuze kuhlakazeke kangcono futhi kugcinwe amanzi.
4. Isilinganiso samanzi
Isilinganiso samanzi (W / C) sibhekisela ku-ratipeation yesisindo samanzi esigabeni sesimende ku-dunstar, futhi iyipharamitha ebalulekile ethinta ukusebenza kodaka. Isilinganiso esifanelekile samanzi-usimende siqinisekisa ukusebenziseka kanye nokunqwabelana kodaka, ngenkathi inika amandla i-HPMC ukuthi isebenzise ngokuphelele izici zayo zokugcina amanzi. Isilinganiso esiphakeme samanzi esiyisimende sisiza i-HPMC ukuthi isatshalaliswe ngokulinganayo kudaka futhi ithuthukise umphumela wokugcina amanzi, kepha isilinganiso esiphakeme ngokweqile samanzi sizoholela ekwehliseni amandla odaka. Ngakho-ke, ukulawulwa kwesilinganiso esilinganiselwe samanzi-cement kubalulekile ekugcinweni kwamanzi kwe-HPMC.
5. Imvelo yokwakha
Imvelo yokwakha (efana nokushisa, umswakama kanye nesivinini somoya) izothinta ngqo izinga lokuhwamuka kwamanzi odongeni, ngaleyo ndlela lithinta umphumela wokugcina amanzi we-HPMC. Emvelweni enokushisa okuphezulu, umswakama ophansi nomoya onamandla, amanzi avele ngokushesha. Ngisho nasekubakhona kwe-HPMC, amanzi asosimende angalahleka masinyane, okuholele ekutholeni indawo yokugcina amanzi okuncishisiwe. Ngakho-ke, ezindaweni ezingezinhle zokwakha, kuvame ukudingeka ukulungisa umthamo we-HPMC noma uthathe ezinye izindlela zokongiwa kwamanzi, njengokupela kwesembozo nokufiphala kwamanzi.
6. Inqubo yokuxuba
Inqubo yokuxuba nayo inomthelela obalulekile ekuhlakazeni nasemthethweni we-HPMC kuDinga. Ukuxuba okugcwele futhi okufanayo kungenza i-HPMC isatshalaliswe kangcono odakeni, yakha uhlelo lokugcinwa kwamanzi olufanayo, futhi ithuthukise ukusebenza kokugcinwa kwamanzi. Ukulahlekelwa okunganele noma ngokweqile kuzothinta umphumela wokuhlakazwa kwe-HPMC futhi kunciphise umthamo wayo wokugcina amanzi. Ngakho-ke, inqubo yokuxuba okunengqondo iyisihluthulelo sokuqinisekisa ukuthi i-HPMC ingathola umphumela wayo wokugcina amanzi.
7. Umphumela Wezinye Izithasiselo
Ezinye izithasiselo, ezinjenge-ejenti yokungena komoya, ama-ejenti anciphisa amanzi, njll., Zivame ukungezwa ku-datar Isibonelo, ama-ejenti okufaka umoya angakhulisa ukugcinwa kwamanzi ngodaka ngokwazisa ama-bubble omoya, kepha ama-bubble amaningi womoya anganciphisa amandla odaka. Umenzeli oncishisiwe wamanzi angashintsha izakhiwo zesimbozo sodaka futhi athinte umphumela wokugcina amanzi we-HPMC. Ngakho-ke, ukusebenzisana ne-HPMC kudingeka kuthathwe njengendlela efanayo lapho ukhetha futhi usebenzisa ezinye izengezo.
Izici ezithinta ukugcinwa kwamanzi kwe-HPMC ku-Masonry udaka ikakhulu zibandakanya ukwakheka kwamangqamuzana kanye nenani le-HPMC, isilinganiso sokwenza amanzi, indawo yokwakha, inqubo yokuxuba nezinye izithasiselo. Lezi zinto zisebenzisana ukunquma ukuphumelela kokugcinwa kwamanzi kwe-HPMC kuDinga. Kuzinhlelo zokusebenza ezisebenzayo, lezi zinto zidinga ukucatshangelwa ngokugcwele futhi inqubo ye-DPMC ye-HPMC idinga ukushintshwa ngokufanelekile ukwenza kahle ukusebenza kokugcinwa kwamanzi kodaka futhi kuqinisekiswe ikhwalithi nokuqina kwephrojekthi yokwakha.
