Udaka lomgubo olomileyo lusetyenziswa kakhulu ngoku.Kukho isalathiso samandla ebhondi kudaka olomileyo lomgubo.Ukususela kumbono wezinto ezibonakalayo, xa into ifuna ukudibanisa kwenye into, idinga i-viscosity yayo.Kukwanjalo nangodaka, isamente +Intlabathi exutywe namanzi ukuze kuzuzwe amandla ebhondi yokuqala, ize inyangelwe zizongezo kunye nesamente ukuze ekugqibeleni kuzuzwe amandla ebhondi afunwa ludaka.Ngoko ke zeziphi izinto ezichaphazela amandla ebhondi?
Isiphumo sezongezo
I-Cellulose ether kunye nomgubo werabha zizongezo eziyimfuneko kumgubo odibanisa udaka obomileyo.Umgubo werabha kudaka ngokuqhelekileyo ngumgubo welatex onyibilikayo onyibilikayo emanzini, onokuthi wohlulwe ube oqinileyo kwaye ubhetyebhetye.Sebenzisa umgubo werabha ohambelanayo ngokweemfuno zemveliso;imisebenzi ephambili Inika unamathele obalaseleyo kwaye inceda ekuphuculeni ukumelana kwamanzi, ukumelana nobushushu, iplastiki kunye nokuguquguquka kodaka.
Indima ye-cellulose ether isetyenziselwa kakhulu ukugcinwa kwamanzi kwi-mortar ukuphucula ukwakhiwa kwemveliso;umzekelo, xa besakha indlu ngaphambili, amagcisa amaninzi axuba isamente nesanti emhlabeni.Emva kokuba begalele amanzi nokuwashukumisa, badla ngokuwabona empompoza amanzi.Xa utyabeka udonga ngolu hlobo lodaka, akufanele nje lube lukhulu, kodwa kunye nenani elincinci kufuneka lisetyenziswe kancinci.Enye imeko kukusula ngelixa uhlikihla.Ukuphuculwa kwezi meko kwakhawuleza.Amanzi avalelwe kwidaka kwaye akavumi ukukhupha.Xa utyabeka udonga, lunokwakhiwa ngokulula njenge-putty, kwaye ubukhulu bunokulawulwa kwaye buncitshiswe;inzuzo enkulu kukuba isantya sokumisa somdaka sinokulawulwa ngokufanelekileyo, kwaye i-samente inokuthi ifakwe ngokupheleleyo i-hydrated, enenzuzo ekuphuculeni ngokubanzi kwamandla omdaka.
shwabana
I-shrinkage ye-mortar inokuthi incedise kumandla okubambisana, okunokuchaphazela indawo yokubambisana kwangempela, ngaloo ndlela yenze iintanda ezingenanto kunye nokulahlekelwa ngokuthe ngqo kumandla okudibanisa;ngoko ke, kufuneka sibe neemfuneko ezingqongqo kwi-gradation yesamente kunye nesanti kwi-mortar , engalawuli kuphela ukucutheka, kodwa igalelo kumandla ebhondi yodaka.Ukongeza, ukunciphisa i-shrinkage kunokuxutywa kunye nezinto ezisebenzayo.Izinto ezisebenzayo zibhekisa kwizixa ezikhulu zesilica esebenzayo kunye ne-alumina esebenzayo.Ayiqini okanye iqiniswe ngokucothayo xa amanzi egalelwe.Ubungakanani bayo be-particle bube buhle, obunokuthi buthathe indawo ye-samente yokuzalisa udaka, ngaloo ndlela inciphisa i-shrinkage jikelele yodaka.
Impembelelo yokungangeni kwamanzi kunye ne-hydrophobic
Ngandlela ithile, ukunqanda amanzi kunye ne-hydrophobicity akuhambisani namandla ebhondi.Ngokomzekelo, kwixesha elidlulileyo, abantu abaninzi babenethemba lokuba neendawo ezingenamanzi kwi-adhesive tile, ezinokuthi zinciphise inkqubo yokwakhiwa kwekhitshi kunye neendonga zokuhlambela, kodwa ukwenzeka akukho phezulu;okokuqala, ukuba udaka lwethu lufuna ukufezekisa i-waterproof okanye i-hydrophobic effects, kufuneka songeze i-agent ye-hydrophobic.Emva kokuba i-agent ye-hydrophobic ixutywe nodaka, ifilimu engabonakaliyo iya kwenza ngokuthe ngcembe phezu komhlaba.Ngale ndlela, xa iileyile zifakwe, amanzi akakwazi ukungena ngokufanelekileyo kwiitile, amandla okumanzisa ayancipha, kwaye amandla okubambisana kwendalo awanakuphuculwa ngexesha lokugcinwa kodaka olulandelayo.
Amandla okudibanisa abhekiselele kumandla aphezulu okudibanisa udaka olusebenza kumaleko asezantsi;
Amandla e-tensile abhekisa kubuchule bomphezulu wodaka ukuxhathisa amandla okuqina ajonge kumphezulu;
Amandla okucheba athetha ukomelela okumiselwa ngokusebenzisa amandla anxuseneyo;
Amandla oxinzelelo athetha ixabiso eliphezulu apho udaka luhluleka, lulinganiswa ngokufaka uxinzelelo.
