Ukuphucula ukuxhathisa kwamanzi kunye nokumelana nokunyibilika komkhenkce: Yongeza ukuxhathisa kwamanzi kunye nokunganyangeki komjikelo wokunyibilika kodaka.
3. Ukusetyenziswa kwe-RDP kwi-polystyrene particle insulation mortar
3.1 Ukuphucula amandla okudibanisa
Kwi-polystyrene particle insulation mortar, ukunamathela ngumsebenzi obalulekileyo.Ekubeni iinqununu ze-polystyrene ngokwazo zizinto ze-hydrophobic, zilula ukuwa kwi-matrix yodaka, okubangelwa ukungaphumeleli kwenkqubo yokugquma.Emva kokongeza i-RDP, ifilimu ye-polymer eyenziwe kwi-mortar inokugubungela ngokufanelekileyo ubuso be-polystyrene particles, ikhulise indawo yokudibanisa phakathi kwabo kunye ne-matrix yodaka, kwaye iphucule amandla okudibanisa phakathi kobuso.
3.2 Ukomelezwa kokumelana neecrack
Ifilimu ye-polymer eyenziwe yi-RDP inokuguquguquka okuphezulu kwaye inokwenza isakhiwo se-mesh ngaphakathi kodaka ukukhusela ukwandiswa kweentanda.Ifilimu ye-polymer inokuphinda ifumane uxinzelelo olwenziwa ngamandla angaphandle, ngaloo ndlela ikhusela ngokufanelekileyo ukuqhekeka okubangelwa ukwanda kwe-thermal kunye nokunciphisa okanye ukucutha.
3.3 Ukuphuculwa komsebenzi wokwakha
I-polystyrene particle insulation mortar idla ngokungabi namanzi amaninzi kunye nobunzima bokusabalalisa ngexesha lokwakha.Ukongezwa kwe-RDP kunokuphucula kakhulu umbane kunye nokusebenza kodaka, okwenza udaka lube lula ukwakha kunye nokuphucula ukusebenza kakuhle kolwakhiwo.Ukongeza, i-RDP inokunciphisa ukwahlulwa kodaka kwaye yenze ukuhanjiswa kwamacandelo odaka ngakumbi.
3.4 Ukuphuculwa kokuxhathisa kwamanzi kunye nokuqina
I-polystyrene particle insulation mortar kufuneka ibe nokuxhathisa okulungileyo kwamanzi kwixesha elide ukuthintela amanzi emvula ekukhukuliseni umaleko wokugquma.I-RDP inokwenza i-hydrophobic layer kwi-mortar ngokusebenzisa iipropati zayo zokwenza ifilimu, ngokufanelekileyo ukuthintela umswakama ukuba ungene kwi-mortar.Ukongeza, ifilimu ebhetyebhetye ebonelelwe yi-RDP inokuphucula iipropati zodaka zokuchasa umkhenkce kunye nokunyibilika kunye nokwandisa ubomi benkonzo yodaka lokugquma.
4. Indlela yokwenza
4.1 Impembelelo yokwenziwa kwefilimu
Emva kokuba i-RDP ihlaziywe kwakhona emanzini kumdaka, i-polymer particles ngokuthe ngcembe idibanisa enye ukuze yenze ifilimu ye-polymer eqhubekayo.Le filimu inokutywina ngokufanelekileyo i-pores encinci kwi-mortar, ithintele ukungena kokufuma kunye nezinto ezinobungozi, kwaye ikhulise amandla okudibanisa phakathi kwamasuntswana.
4.2 Impembelelo yojongano oluphuculweyo
Ngethuba lenkqubo yokuqina kodaka, i-RDP inokufudukela kwi-interface phakathi kodaka kunye neengqungquthela ze-polystyrene ukwenza i-interface layer.Le filimu ye-polymer ine-adhesion eqinile, enokuphucula kakhulu amandla okudibanisa phakathi kweengqungquthela ze-polystyrene kunye ne-matrix yodaka kunye nokunciphisa isizukulwana sokuqhekeka kwe-interface.
4.3 Ukuphucula ukuguquguquka
Ngokwenza ulwakhiwo lwenethiwekhi eguquguqukayo ngaphakathi kodaka, i-RDP yonyusa ukuguquguquka okupheleleyo kodaka.Le nethiwekhi eguquguqukayo inokusasaza uxinzelelo lwangaphandle kunye nokunciphisa uxinzelelo loxinzelelo, ngaloo ndlela iphucula ukuchasana nokuqhekeka kunye nokuqina kodaka.
5. Isiphumo sokongezwa kweRDP
5.1 Imali eyongeziweyo efanelekileyo
Isixa se-RDP esongeziweyo sinempembelelo ebalulekileyo ekusebenzeni kwe-polystyrene particle insulation mortar.Ngokubanzi, isixa seRDP esongeziweyo siphakathi kwe-1-5% yobunzima besamente bubonke.Xa imali eyongeziweyo iphakathi, inokuphucula kakhulu amandla okudibanisa, ukuchasana nokuqhekeka kunye nokusebenza kokwakhiwa kodaka.Nangona kunjalo, ukongezwa okugqithisileyo kunokunyusa iindleko kwaye kuchaphazele ubulukhuni kunye namandla oxinzelelo lodaka.
5.2 Ubudlelwane phakathi kwemali eyongeziweyo kunye nokusebenza
Amandla e-Bond: Njengoko inani le-RDP elongeziweyo linyuka, amandla okubambisana omdaka akhula ngokuthe ngcembe, kodwa emva kokufikelela kumlinganiselo othile, umphumo wokwandisa ngakumbi imali eyongeziweyo ekuphuculeni amandla okubambisana alinganiselwe.
Ukuchasana nokuqhekeka: Isixa esifanelekileyo se-RDP sinokuphucula kakhulu ukuxhathisa kokuqhekeka kodaka, kwaye okuncinci kakhulu okanye ukongeza okuninzi kunokuchaphazela isiphumo salo esilungileyo.
Ukusebenza kolwakhiwo: I-RDP iphucula ukuguquguquka kunye nokusebenza kodaka, kodwa ukongezwa okugqithisileyo kuya kubangela ukuba udaka lube ne-viscous kakhulu, engabangeli imisebenzi yokwakha.
6. Ukusetyenziswa okusebenzayo kunye nesiphumo
6.1 Ityala lokwakha
Kwiiprojekthi zokwenyani, i-RDP isetyenziswa ngokubanzi kwiinkqubo zokugquma kwangaphandle (EIFS), udaka lwesamente kunye nodaka oludityanisiweyo.Ngokomzekelo, kulwakhiwo lwangaphandle lwe-insulation yodonga lwe-complex enkulu yorhwebo, ngokongeza i-3% ye-RDP kwi-polystyrene particle insulation mortar, ukusebenza kokwakhiwa kunye nomphumo we-insulation of the mortar kwaphuculwa kakhulu, kwaye umngcipheko wokuqhekeka ngexesha lokwakha wawuphuculwe kakhulu. kuncitshiswe ngempumelelo.
6.2 Ukuqinisekiswa kovavanyo
Uphononongo lokulinga lubonise ukuba i-polystyrene particle insulation mortar kunye nokongezwa kwe-RDP ibe nophuculo olubalulekileyo kumandla okudibanisa, amandla oxinzelelo kunye nokumelana nokuqhekeka kwiintsuku ezingama-28.Xa kuthelekiswa neesampuli zokulawula ngaphandle kwe-RDP, amandla okubambisana kweesampuli ze-RDP ezongeziweyo zanda ngo-30-50% kwaye ukuchasana nokuqhekeka kwanda ngo-40-60%.
I-redispersible latex powder (RDP) inexabiso elibalulekileyo lesicelo kwi-polystyrene particle insulation mortar.Iphucula ngokufanelekileyo ukusebenza okubanzi kodaka lwe-insulation ngokwandisa amandla okubopha, ukuphucula ukumelana nokuqhekeka, ukuphucula ukusebenza kolwakhiwo, kunye nokuphucula ukuxhathisa kwamanzi kunye nokuqina.Kwizicelo ezisebenzayo, ukongezwa okufanelekileyo kwe-RDP kunokuphucula kakhulu ukuzinza kunye nokuqina kwenkqubo yokugquma, ukubonelela ngesiqinisekiso esibalulekileyo sokwakha ukugcinwa kwamandla kunye nokhuseleko lwesakhiwo.
