Indima ye-latex powder ephinda ikwazi ukuchithwa kwidaka

1. Indlela yokusebenza ye-disperible latex powder kwi-mortar

Ubungakanani bepolymer ye-emulsion enokuthi yenziwe ngokunyibilikisa i-latex powder ehlakaziweyo emanzini itshintsha isakhiwo se-pore sodaka, kwaye umphumo wayo wokungenisa umoya unciphisa ukuxinana kodaka, uhamba kunye nokunciphisa i-pore ebalulekileyo kunye nokusabalalisa okufanayo kulo lonke. . Ipolymer yazisa inani elikhulu lamaqamza omoya amancinci avaliweyo kudaka lwesamente, oluphucula kakhulu ukusebenza kodaka olusanda kuxutywa. Ngelo xesha, ezi zibhubhu zomoya zinokuvala i-capillary ngaphakathi kodaka oluqinileyo, kwaye i-hydrophobic layer phezu kwe-capillary ivaliwe. Iiseli ezivaliweyo; okubaluleke ngakumbi, xa i-samente i-hydrated, i-polymer iphinda ifake ifilimu kwaye ibambelele kwi-sement hydrate ukwenza i-uniform network structure, kunye ne-polymer kunye ne-hydrate ingena komnye nomnye ukwenza isigaba esiqhubekayo. Esi sakhiwo esidibeneyo senza i-polymer-modified cement mortar, kwaye i-aggregate iphinda iboshwe kwi-mortar enzima yinto edibeneyo. Ngenxa yemodyuli ephantsi ye-elastic ye-polymer, imeko yoxinzelelo lwangaphakathi lodaka lwesamente luphuculwe, olunokumelana ne-deformation kunye nokunciphisa uxinzelelo, kunye nokuba nokwenzeka kwe-micro-cracks nayo encinci; ngaphezu koko, i-polymer fiber iwela i-micro-cracks kwaye isebenze njengebhulorho kunye nokuzalisa Umphumo unqanda ukusasazeka kweentanda kwaye wenze ii-micro cracks zinyamalale kwiindawo apho kukho iipolymers ezininzi. Ukunciphisa i-micro-cracks ngaphakathi kwe-slurry kunciphisa amandla okufunxa amanzi kwi-capillary ngaphakathi kodaka, kwaye amandla okulwa nokufakwa kwamanzi omdaka aphuculwe ngaxeshanye.

2. Ukumelana nokunyibilika komkhenkce

Umkhenkce-ncibilika welahleko yobunzima bebhloko yovavanyo lodaka lwesamente kunye ne-latex powder isezantsi kakhulu kunesampulu ngaphandle kokongeza i-latex powder, kwaye ngokunyuka kwe-latex powder ukongeza, okuncinci izinga lokulahleka kobunzima, kungcono umkhenkce. -thaw ukumelana nesiqwenga sovavanyo. , xa umxholo we-latex powder udlula i-1.5%, izinga lokulahlekelwa kwe-freeze-thaw mass litshintsha kancinci.

3. Impembelelo ye-latex powder kwiipropati zomatshini zodaka

Amandla oxinzelelo omdaka ayancipha ngokunyuka komxholo we-latex powder, kwaye ukuba ixutywe ne-cellulose ether, amandla oxinzelelo anokunciphisa ngokufanelekileyo; amandla e-flexural kunye nokuqina kwebhondi kwanda ngokunyuka komxholo we-latex powder; Xa inani le-latex powder lingaphantsi kwe-2%, amandla ebhondi yomdaka akhula kakhulu, kwaye ke ukunyuka kunciphisa; i-latex powder inokuphucula kakhulu ukusebenza okubanzi kodaka, kwaye isixa esifanelekileyo yi-2% -3% yezinto ze-cementitious.

4. Ixabiso lemarike kunye nethemba le-latex powder eguqulwe ngodaka lwezorhwebo

Ukusebenzisa i-latex powder ukuguqula udaka lwesamente kunokuvelisa udaka olomileyo lwepowder kunye nemisebenzi eyahlukeneyo, ebonelela ngethemba elibanzi lemarike yokuthengiswa kodaka. Njengekhonkrithi yorhwebo, udaka lwezorhwebo luneempawu zemveliso esembindini kunye nonikezelo olumanyeneyo, olunokudala iimeko ezifanelekileyo zokwamkela ubugcisa obutsha kunye nezixhobo, ukuphumeza ulawulo olungqongqo lwekhwalithi, ukuphucula iindlela zokwakha, kunye nokuqinisekisa umgangatho weprojekthi. Ukuphakama kodaka lwezorhwebo ngokubhekiselele kumgangatho, ukusebenza kakuhle, uqoqosho kunye nokukhuselwa kwendalo kuye kwavezwa ngakumbi kunye nophando kunye nophuhliso kunye nokuthandwa kunye nokusetyenziswa, kwaye iqatshelwa ngokuthe ngcembe. Inokushwankathelwa ngamagama asibhozo: enye ingaphezulu, ezimbini ziyakhawuleza, ezintathu zilungile, kunye namaphondo amane (elinye lingaphezulu, kukho iindidi ezininzi; Ukonga abasebenzi, ukonga izinto eziphathekayo, ukonga imali, ukungakhathazeki) . Ukongeza, ukusetyenziswa kodaka lwezorhwebo kunokufikelela kulwakhiwo oluphucukileyo, kuncitshiswe indawo zokupakisha izinto eziphathekayo, kwaye kunqande ukubhabha kothuli, ngaloo ndlela kuncitshiswe ukungcoliseka kwendalo kunye nokukhusela inkangeleko yesixeko.
