Kutheni le nto imfuneko yokugcinwa kwamanzi kwidaka iphezulu kangaka, kwaye zeziphi iingenelo ezibalaseleyo zodaka ngokugcinwa kakuhle kwamanzi? Mandikwazise ngokubaluleka kokugcinwa kwamanzi e-HPMC kwidaka!
Isidingo sokugcinwa kwamanzi
Ukugcinwa kwamanzi eludaka kubhekiselele kubuchule bodaka ukugcina amanzi. Udaka olunogcino lwamanzi olulambathayo kulula ukopha kwaye lwahlulahlulwe ngexesha lokuthuthwa kunye nokugcinwa, oko kukuthi, amanzi adada ngaphezulu, isanti kunye nesamente ezantsi, kwaye kufuneka ivuselelwe kwakhona phambi kokusetyenziswa.
Zonke iintlobo zeziseko ezifuna udaka lokwakhiwa zinomlinganiselo othile wokufunxa amanzi. Ukuba ukugcinwa kwamanzi omdaka kubi, kwinkqubo yokusetyenziswa kodaka, ngokude nje ukuba i-mortar edibeneyo idibene nebhloko okanye isiseko, i-mortar edibeneyo edibeneyo iya kuxutywa. Kwangaxeshanye, umphezulu wodaka ukhupha amanzi emoyeni, nto leyo ebangela ukufuma okungonelanga kodaka ngenxa yokulahleka kwamanzi, okuchaphazela ukuhanjiswa kwesamente ngakumbi, kwaye kuchaphazela ukukhula okuqhelekileyo kwamandla odaka, okukhokelela ekubeni amandla, ngakumbi amandla ojongano phakathi komzimba oqinileyo wodaka kunye nomgangatho wesiseko. iba ngaphantsi, ibangela ukuba udaka luqhekeke kwaye liwe. Ngodaka olunokugcinwa kakuhle kwamanzi, i-cement hydration yanele ngokwaneleyo, amandla anokuphuhliswa ngokuqhelekileyo, kwaye inokudibaniswa kakuhle kwisiseko sesiseko.
Udaka olulungelelanisiweyo luvame ukwakhiwa phakathi kweebhloko zokufunxa amanzi okanye zisasazwe kwisiseko, zenze yonke into kunye nesiseko. Iimpembelelo zokugcinwa kwamanzi okulambathayo kodaka kumgangatho weprojekthi ngolu hlobo lulandelayo:
1. Ngenxa yokulahlekelwa kwamanzi amaninzi odaka, ukusetwa okuqhelekileyo kunye nokuqina kodaka kuyachaphazeleka, kwaye ukunamathela phakathi kodaka kunye nomphezulu kuncitshisiwe, okungekho nje ukuphazamiseka kwimisebenzi yokwakha, kodwa kunciphisa amandla ombane. i-masonry, ngaloo ndlela inciphisa kakhulu umgangatho weprojekthi;
2. Ukuba umdaka awubopheli kakuhle, amanzi aya kuxutywa ngokulula ngezitena, okwenza udaka lome kakhulu kwaye lube lukhulu, kwaye isicelo siya kungalingani. Ngethuba lokuphunyezwa kweprojekthi, ayiyi kuchaphazela kuphela inkqubela phambili, kodwa yenza udonga lube lula ukuqhekeka ngenxa yokuncipha.
Ngoko ke, ukwandisa ukugcinwa kwamanzi omdaka akuncedi nje kuphela ukwakhiwa, kodwa kwandisa amandla.
2. Iindlela zemveli zokugcina amanzi
Isisombululo semveli kukunkcenkceshela umaleko wesiseko kunye namanzi ngokuthe ngqo kumphezulu womgangatho wesiseko, okuya kubangela ukufunxwa kwamanzi komgangatho wesiseko ukuba kuhlakazeke kakhulu ngenxa yokungafani kobushushu, ixesha lokunkcenkceshela, kunye nokunkcenkceshela okufanayo. Uluhlu lwesiseko lunokufakwa kwamanzi okuncinci kwaye luya kuqhubeka nokufunxa amanzi kumdaka. Ngaphambi kwe-cement hydration, amanzi ahlanjululwa, achaphazela ukungena kwe-cement hydration kunye nemveliso ye-hydration kwisiseko; Isantya sokufuduka esiphakathi siyacotha, kwaye kwakhiwe umaleko otyebileyo wamanzi phakathi kodaka kunye ne-substrate, ekwachaphazela amandla ebhondi. Ngoko ke, ukusebenzisa indlela yokunkcenkceshela isiseko esiqhelekileyo akukwazi nje ukucombulula ngokufanelekileyo ingxaki yokutshatyalaliswa kwamanzi aphezulu kwisiseko sodonga, kodwa kuchaphazela amandla okubambisana omdaka kunye nesiseko, okubangelwa ukukhupha kunye nokuqhekeka okomileyo.
3. Indima yogcino lwamanzi olusebenzayo
Iipropathi eziphezulu zokugcina amanzi zodaka zineenzuzo ezininzi:
1. Umsebenzi ogqwesileyo wokugcinwa kwamanzi wenza ukuba udaka luvuleke ixesha elide, kwaye lunenzuzo yokwakhiwa okukhulu, ixesha elide lokusebenzisa kwi-barrel, i-batch mixing kunye nokusetyenziswa kwe-batch, njl.;
2. Ukugcinwa kwamanzi okulungileyo kunokunyusa ngokupheleleyo i-samente kwi-mortar kwaye kuphuculwe ngokufanelekileyo ukusebenza kwe-bonding yodaka;
3. Udaka lunokugcinwa kwamanzi okugqwesileyo, okwenza ukuba udaka lungabi lula ukuhlukana kunye nokopha. Ngoku, ukusebenza kunye nokusebenza kodaka kuphuculwe.
