Zithini iziphumo ezinazo umgubo wepolymer ophinda uqhekeke kumandla emortar?

Ukudibanisa iipowder zepolymer eziphinda zichithwe (i-RPP) kwiifomyula zemortar kuchaphazela kakhulu iimpawu zamandla ezinto eziphumayo. Eli nqaku liphonononga imiphumo ye-RPP kumandla emortar, kubandakanya nempembelelo yazo kumandla okuxinzelela, amandla okugoba, amandla okuncamathela, kunye nokumelana nempembelelo.

1. Amandla oxinzelelo:

Amandla okucinezela luphawu oluphambili lwe-mortar, olubonisa amandla ayo okumelana nemithwalo ye-axial. Ukongezwa kwee-RPP kunokunyusa amandla okucinezela ngeendlela ezahlukeneyo:

Ukwanda koBumbano:

Ii-RPP zisebenza njengee-arhente zokubopha, zikhuthaza ukudibana okungcono phakathi kwamasuntswana e-mortar. Oku kubambisana okuphuculweyo phakathi kwamasuntswana kuncedisa ekuqineni okuphezulu ngokunciphisa izithuba zangaphakathi kunye nokuphucula ukuthembeka kwesakhiwo sezinto.

Ukufunxwa Kwamanzi Okunciphileyo:

Ii-RPP ziphucula ukugcinwa kwamanzi kwi-mortar, nto leyo evumela ukufuma kwezinto ezisebenzisa isamente ngokufanelekileyo. Ukufuma ngokufanelekileyo kukhokelela kwizakhiwo ezincinci ezixineneyo ezinee-voids ezimbalwa, nto leyo ekhokelela ekubeni amandla aphezulu okuxinwa kunye namazinga aphantsi okufunxwa kwamanzi.

Amandla Okuzivumelanisa Nezimo Aphuculweyo:

Ukuguquguquka okunikezelwa zii-RPPs kunokuchaphazela ngokungathanga ngqo amandla okuxinzelela ngokuthintela ukuqhekeka okuncinci ekukhuleni nasekubuthakazeni izinto. Iimortars eziqulethe ii-RPPs zihlala zibonisa amandla aphuculweyo okuxinzelela, ahambelana nokumelana okuphuculweyo namandla okuxinzelela.

2. Amandla okuGuquka:

Amandla okugoba alinganisa amandla ezinto zokuxhathisa ukugoba okanye ukuguquka phantsi kwemithwalo esetyenzisiweyo. Ii-RPP zinegalelo ekuphuculeni amandla okugoba kwi-mortar ngokusebenzisa ezi ndlela zilandelayo:

Ukomelela kweBond:

Ii-RPP zonyusa ukunamathelana phakathi kwezinto ze-mortar kunye nomphezulu we-substrate, nto leyo ebangela ukuba kubekho iibhondi eziqinileyo kunye nokunciphisa ukuhlukana. Oku kuqina kwebhondi okuphuculweyo kuthetha ukuba kukho ukumelana okuphezulu nokugoba kunye noxinzelelo lokuxinana, ngaloo ndlela kwandisa amandla okuguquguquka.

Umanyano Oluphuculweyo:

Iimpawu ezidibeneyo ze-RPP-modified mortar zinceda ukusasaza imithwalo esetyenzisiweyo ngokulinganayo kwicandelo elinqamlezileyo lezinto. Olu sasazo lulinganayo lunciphisa uxinzelelo lwendawo kwaye luthintele ukungaphumeleli kwangaphambi kwexesha, okubangela amandla aphezulu e-flexural.

3. Amandla Okuncamathelisa:

Amandla okuncamathela abhekisa kubudlelwane phakathi kodaka kunye nomphezulu we-substrate. Ii-RPP zidlala indima ebalulekileyo ekuphuculeni amandla okuncamathela ngeendlela ezilandelayo:

Ukunamathela okuphuculweyo:

Ii-RPP zikhuthaza ukunamathela okungcono ngokwenza ifilimu encinci, eguquguqukayo kwiindawo ze-substrate, nto leyo ephucula indawo yoqhagamshelwano kwaye ikhuthaza ukunamathelana phakathi kobuso. Oku kunamathelana okuphuculweyo kuthintela ukuqhekeka kwaye kuqinisekisa unxibelelwano oluqinileyo phakathi kwe-mortar kunye ne-substrate.

Ukuqhekeka okuncitshisiweyo kokuncipha:

Ukuguquguquka kunye neempawu zokugcina amanzi ze-RPPs zinceda ekunciphiseni ukuqhekeka kwe-mortar, nto leyo enokuphazamisa amandla e-glue. Ngokunciphisa ukwakheka kwe-crack kunye nokwanda kwayo, ii-RPPs zinegalelo kwi-glue bonds eqinileyo nehlala ixesha elide.

4. Ukumelana neMpembelelo:

Ukumelana neempembelelo kulinganisa amandla ezinto zokumelana neempembelelo ezikhawulezileyo, ezinamandla aphezulu ngaphandle kokuqhekeka okanye ukuqhekeka. Ii-RPP zonyusa ukumelana neempembelelo zesinyithi ngokusebenzisa ezi ndlela zilandelayo:

Ukuqina Okunyukileyo:

Udaka oluguqulwe yi-RPP lubonakalisa ukuqina okuphezulu ngenxa yokuguquguquka kwalo okuphuculweyo kunye nokuguquguquka. Olu kuqina lukhulayo luvumela izinto ukuba zifunxe kwaye zichithe amandla okubetha ngokufanelekileyo, nto leyo enciphisa amathuba okuqhekeka okanye ukungaphumeleli xa kungqubana.

Ukuqina Okuphuculweyo:

Ukuqina okunikezelwa zii-RPP kwandisa ubomi benkonzo yesamente, kuqinisekisa ukusebenza kwexesha elide phantsi kweemeko ezinzima. Oku kuqina okuphuculweyo kuthetha ukuba umbane ungangeni kakhulu kumonakalo obangelwa yimpembelelo, ukukrazula, kunye nezinye iintlobo zoxinzelelo loomatshini.

Ukuqukumbela, iipowder zepolymer eziphinda zichithwe zidlala indima ebalulekileyo ekuphuculeni iimpawu zokuqina kwesamente, kubandakanya amandla okucinezelwa, amandla okugoba, amandla okuncamathela, kunye nokumelana nempembelelo. Ngokuphucula ukuhambelana, ukunamathela, kunye nokuqina, ii-RPP zinegalelo ekuphuhlisweni kweefomyula zesamente ezisebenzayo eziphezulu ezifanelekileyo kwiintlobo ngeentlobo zezicelo zokwakha.
