Ziziphi iindima ezidlalwa kwakhona umgubo wepolymer kudaka?

I-polymer powder ehlaziywayo (i-RPP) idlala indima ebalulekileyo kwiindlela zokubumba udaka, ngokukodwa kwi-cementitious kunye ne-polymer-modified mortars. Nazi iindima eziphambili ezenziwa ngumgubo wepolymer kwakhona kudaka:

1. Ukuphucula i-Adhesion: I-RPP iphucula ukunamathela kodaka kwii-substrates ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry, iplanga kunye nesinyithi. Oku kubambelela okuphuculweyo kunceda ukukhusela i-delamination kunye nokuqinisekisa ukudibanisa okuqinileyo phakathi kodaka kunye ne-substrate.
2. Ukuphucula i-Flexibility: I-RPP inika ukuguquguquka kumdaka, okwenza kube nzima ukumelana nokuqhekeka kunye nokuguqulwa. Oku kubaluleke kakhulu kwizicelo apho i-substrate inokufumana ukunyakaza okanye ukwandiswa kwe-thermal kunye nokunciphisa.
3. Ukwandiswa kokugcinwa kwamanzi: I-RPP iphucula iipropati zokugcina amanzi zodaka, okuvumela ukuba ukuhanjiswa kwexesha elide kwezinto ze-cementitious. Oku kubangela ukusebenza kakuhle, ixesha elivulekileyo elongeziweyo, kunye nokuphucula ukunamathela, ngakumbi kwiimeko ezishushu okanye ezinomoya.
4. Ukuphucula ukuSebenza: I-RPP iphucula ukusebenza kunye nokuhambelana kodaka, okwenza kube lula ukuxuba, ukusebenzisa, kunye nokusabalalisa. Oku kuvumela ukhuselo olungcono kunye nesicelo esifanayo, ukunciphisa amathuba okuba ne-voids okanye izithuba kudaka olugqityiweyo.
5. Ukunciphisa i-Shrinkage kunye ne-Cracking: Ngokuphucula ukubambelela, ukuguquguquka, kunye nokugcinwa kwamanzi, i-RPP inceda ukunciphisa ukuncipha kunye nokuqhekeka kumdaka. Oku kunenzuzo ngakumbi kwizicelo apho ukuqhekeka kwe-shrinkage kunokuphazamisa ingqibelelo kunye nokuqina kodaka.
6. Ukwandisa Amandla kunye noKuhlala ixesha elide: Ukusetyenziswa kwe-RPP kunokuphucula iimpawu zemishini yodaka, kubandakanywa amandla oxinzelelo, amandla okuguquguquka, kunye nokuxhatshazwa kwe-abrasion. Oku kubangela udaka oluhlala ixesha elide kunye nexesha elide, olulungele uluhlu olubanzi lwezicelo zokwakha.
7. Ukuguqula i-Rheology: I-RPP inokuguqula iimpawu ze-rheological zodaka, kuquka i-viscosity, i-thixotropy, kunye ne-sag resistance. Oku kuvumela ulawulo olungcono kwisicelo kunye nokubekwa kodaka, ngakumbi kwiindawo ezithe nkqo okanye ngaphezulu.
8. Ukubonelela ngokumelana ne-Freeze-Thaw Resistance: Iindidi ezithile ze-RPP zenzelwe ukuphucula ukunyanzeliswa kwe-freeze-thaw yodaka, okwenza ukuba ifaneleke ukusetyenziswa kwiindawo ezibandayo okanye kwiindawo apho imijikelo yokuqhaqhazela yiqhwa.

umgubo wepolymer odispersible udlala indima ebalulekileyo ekwandiseni ukusebenza, ukuqina, kunye nokuguquguquka kokwenziwa kodaka, okubenza bafaneleke kuluhlu olubanzi lwezicelo zokwakha, kubandakanya ukufakela iithayile, istucco kunye nokutyabeka, ukulungiswa kunye nokubuyiselwa, kunye nokuvalwa kwamanzi.
