I-RDP yodaka olomileyo oluxutyiweyo

Udaka olomileyo oluxubeneyo luhlobo lomxube wegranular kunye nomgubo we-aggregate kunye ne-inorganic cementing material, izinto ezigcina amanzi ezityebisayo, i-agent yokunciphisa amanzi, i-anti-cracking, i-agent ekhupha amagwebu kunye nezinye izongezo ezixutywe ngokulinganayo kumlinganiselo othile. Ithuthelwa kwindawo yesiza ngelori yetanki ekhethekileyo okanye ingxowa yephepha evaliweyo engangeni manzi, ize ixutywe namanzi. Ngoku ukongeza kwisamente kunye nesanti kwinani elikhulu lodaka oluxubeneyo olomileyo, inani elingaphezulu linokuphinda liphindwe kwakhona.ipolymer powder RDP. Ngenxa yexabiso layo eliphezulu kunye nempembelelo enkulu kwiipropati zodaka, yinto ekugxilwe kuyo ingqalelo yabantu. Impembelelo ye-dispersibleipolymer powder RDPkwiipropati zodaka kwaxoxwa ngazo kweli phepha.

1 Indlela yoVavanyo

Ukuze kumiselwe impembelelo ye-dispersibleipolymer powder RDPumxholo kwiipropati zodaka lwe-polymer, Amaqela amaninzi okwakhiwa ayeyilwe ngendlela yovavanyo lwe-orthogonal kwaye avavanywa ngokuhambelana ne-dbjoi-63-2002, umgangatho woHlolo loMgangatho we-polymer Mortar ukwenzela ukufakwa kwangaphandle kodonga lwangaphandle, ukufumanisa impembelelo yodaka lwepolymer kwi-tensile. Amandla ebhondi, ukuqina kwebhondi ye-shear kunye namandla acinezelayo, amandla okuguquguquka kunye nomlinganiselo wokuguquguquka kodaka lwepolymer kwisiseko sekhonkrithi.

Eyona nto iphambili ekrwada yi-P-04 2.5-pu ye-silicon sement; I-RE5044 kunye ne-R1551Z inokuphinda ihlakazwe kwaye iphinde ihlakazwe i-emulsion powder; I-70-140 ye-mesh ye-quartz isanti; Ezinye izongezo.

2 Impembelelo ye-dispersibleipolymer powder RDPkwiipropati zodaka lwepolymer

2.1 Ukuqina kwebhondi kunye neempawu zebhondi yoxinzelelo lokucheba

Ngokunyuka kwe-dispersibleipolymer powder RDPUmxholo, ukomelela kwebhondi ebambekayo kunye namandla acinezelayo we-shear bond yodaka lwepolymer kunye nodaka lwesamente nawo ayanda, kwaye iigophe ezintlanu zinyuka zihambelane nokunyuka komxholo wesamente. Onke amanqaku afanelekileyo anomlinganiselo ophakathi, kodwa uhlalutyo lobungakanani lunokusasazwa umxholo we-emulsion powder kwiqondo lempembelelo yentsebenzo ye-samente yodaka unokubona ukuba ngokunyuka kwe-emulsion echithwayo kwakhona umxholo we-emulsion powder kwi-bonding yamandla e-cement mortar, i-polymer mortar compressive shear strength. intsingiselo yokukhula ngokulandelelana, intsingiselo iyonke yokunyuka kwe-1% ukusasazekaipolymer powder RDP, amandla okudibanisa anyuke nge-0.2 MPa, amandla okudibanisa i-shear bond anyuke nge-0.45MPA.

2.2 Iimpawu zokucinezela/ukugoba kodaka ngokwalo

Ngokunyuka komxholo we-dispersibleipolymer powder RDP, amandla oxinzelelo kunye namandla okuguquguquka kwe-polymer mortar yehla, ebonisa ukuba i-polymer inempembelelo yokuthintela kwi-hydration ye-samente. IKHIWANE. I-4 ibonisa impembelelo ye-dispersibleipolymer powder RDPumxholo kumlinganiselo wokunyanzeliswa kunye nokusongwa kwe-polymer mortar. , ngokunyuka komxholo wokuphinda uhlakazweipolymer powder RDP, i-self-compression ratio ye-polymer mortar iyancipha, ebonisa ukuba i-polymer iphucula ukuqina kodaka. Impembelelo yomxholo we-dispersibleipolymer powder RDPekusebenzeni kodaka lwepolymer kunokucazululwa ngokobungakanani ngokweavareji enobunzima benqaku ngalinye lolungelelwaniso. Ngokunyuka komxholo we-dispersibleipolymer powder RDP, amandla oxinzelelo, amandla okuguquguquka kunye nomlinganiselo we-flexural we-polymer mortar ibonisa umgca wokunciphisa umzila. Amandla acinezelayo, amandla okuguquguquka kunye ne-flexural ratio ye-dispersibleipolymer powder RDPyehle nge-1.21 MPa, 0.14MPa kunye ne-0.18 nge-1%. Kwakhona kunokubonwa ukuba ngenxa yokwanda kwenani le-redispersibleipolymer powder RDP, ukuguquguquka kodaka kuye kwaphuculwa.

2.3 Uhlalutyo lobungakanani bempembelelo yomlinganiselo wesamente-isanti kwiipropati zodaka lwepolymer

Kwi-polymer mortar, umlinganiselo wesamente-isanti kunye ne-dispersibleipolymer powder RDPumxholo usebenzisana ngokuthe ngqo omnye komnye, ngoko ke kuyimfuneko ukuxoxa ngempembelelo yomlinganiselo wesamente-isanti ngokwahlukileyo. Ngokwendlela yovavanyo lwe-orthogonal yokusetyenzwa kwedatha iya kwahluka ngokwahlukileyo njengezinto eziguquguqukayo, ukusabalalisa kunokunxulunyaniswa neipolymer powder RDPUmxholo njengento eqhubekayo yokuzoba umahluko kwimpembelelo yotshintsho kumthamo wodaka, unokubona ukuba kunye nokwanda kokumahluko ekusebenzeni kodaka lwesamente lodaka lwepolymer kunye nokusebenza kodaka lwepolymer ngokwalo luyancipha ngokulandelelana, Intsingiselo jikelele kukuba Amandla ebhondi yodaka lodaka lwepolymer ukuya kudaka lwesamente ayancipha nge-0.12MPa, amandla oxinzelelo lwe-shear bond ahla nge-0.37MPa, amandla oxinzelelo odaka lwepolymer ahla nge-4.14MPa, amandla okuguquguquka ayancipha nge-0.72MPa, kwaye umlinganiselo we-flexural wehla nge-0.270 ngokunyuka ngakunye komlinganiselo wesamente nesanti

3 Impembelelo yokuphinda ihlakazweipolymer powder RDPkwi-tensile bonding phakathi kodaka lwepolymer kunye nebhodi ye-EPS yogwebu lwepolystyrene DB JoI-63-2002 umgangatho uphakamisa ukuba ukudityaniswa kodaka lwepolymer kudaka lwesamente kunye nebhodi ye-EPS iyaphikisana.

Eyangaphambili ifuna i-polymer mortar ukuba ibe ngqongqo, ngelixa le yokugqibela ifuna ukuguquguquka kwayo ukuba ibe phezulu, kodwa ngokuqwalasela ubunjineli bokufakelwa kwangaphandle kokubini ukunamathela eludongeni oluqinileyo kunye nebhodi ye-EPS eguquguqukayo, ngexesha elifanayo ukuqinisekisa ukuba iindleko aziphezulu kakhulu. Ke ngoko, impembelelo yomxholo we-dispersibleipolymer powder RDPkwipropathi yebhondi eguquguqukayo yodaka lwepolymer idweliswe ngokwahlukeneyo ukugxininisa ukubaluleka kwayo.

4Impembelelo yeentlobo eziphinda zihlakazweipolymer powder RDPkumandla okudibanisa kwibhodi ye-EPS

R5,C1,P23 iintlobo eziphinda zihlakazweipolymer powder RDPbakhethwa phesheya. Taiwan D2,D4 2 iintlobo; I-S1 yasekhaya, i-S2 2 iintlobo ze-7 iintlobo; Ibhodi yePolystyrene eyenziwe eBeijing 18kg / ibhodi ye-EPS enemigca. Ngokutsho kwe-dbJ01-63-2002 esemgangathweni, i-stretch bond iphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde idibanisweipolymer powder RDPyebhodi ye-EPS inokuhlangabezana neemfuno eziqinileyo neziguquguqukayo zokwenziwa kwebhondi yodaka lwepolymer ngaxeshanye.
