Ziziphi iimpawu zodaka ezinokuphucula kwakhona umgubo wepolymer?

Iipolymer powders eziphinda zisetyenziswe (RPP) ziqhele ukusetyenziswa kwimixube yodaka ukunyusa iipropati ezahlukeneyo kunye neempawu zokusebenza.Nazi ezinye zeempawu eziphambili zodaka ezinokuphuculwa yi-RPP:

1. Ukubambelela: I-RPP iphucula ukunamathela kodaka kwii-substrates ezifana nekhonkrithi, i-masonry, iplanga kunye neendawo zetsimbi.Oku kuncamathela okuphuculweyo kunceda ukukhusela i-delamination kunye nokuqinisekisa ukuhlangana olomeleleyo phakathi kodaka kunye ne-substrate.
2. Amandla e-Flexural: Ukubandakanya i-RPP kwiifom zodaka kunokunyusa amandla e-flexural, okwenza udaka luxhathise ngakumbi ukuqhekeka kunye nokuguqulwa.Oku kubaluleke kakhulu kwizicelo apho i-substrate inokufumana ukunyakaza okanye ukwandiswa kwe-thermal kunye nokunciphisa.
3. Ukugcinwa kwamanzi: I-RPP iphucula iipropathi zokugcina amanzi zodaka, ivumela ukuhanjiswa kwexesha elide lezinto zesamente.Oku kubangela ukusebenza kakuhle, ixesha elivulekileyo elongeziweyo, kunye nokuphucula ukunamathela, ngakumbi kwiimeko ezishushu okanye ezinomoya.
4. 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-RPPs inceda ukunciphisa i-shrinkage kunye nokuqhekeka kumdaka.Oku kunenzuzo ngakumbi kwizicelo apho ukuqhekeka kwe-shrinkage kunokuphazamisa ingqibelelo kunye nokuqina kodaka.
6. Ukuqina: Ukusetyenziswa kwe-RPP kunokomeleza ukuqina kodaka ngokunyusa ukuchasana kwayo nemozulu, uhlaselo lweekhemikhali, kunye nokuqhawuka.Oku kubangela udaka oluhlala ixesha elide olugcina ingqibelelo yesakhiwo ngokuhamba kwexesha.
7. I-Thermal and Moisture Resistance: I-RPP inokuphucula ukunyanzeliswa kwe-thermal kunye nokufuma kwe-mortar, iyenze ilungele ukusetyenziswa kwiimeko ezininzi zokusingqongileyo, kubandakanywa imijikelezo ye-freeze-thaw, umswakama ophezulu, kunye nokutshintsha kweqondo lokushisa.
8. Amandla oMbhobho: I-RPP inegalelo kumandla ebhondi yodaka, iqinisekisa ukunamathela okuqinileyo phakathi kweengqimba zodaka lomntu kunye naphakathi kodaka kunye ne-substrate.Oku kubalulekile ekuphumezeni iindibano zokwakha ezithembekileyo nezihlala ixesha elide.

ukudityaniswa kwepolymer powders enokuphinda ihlakazwe kwimixube yodaka kunika izibonelelo ezininzi, kubandakanywa ukunamathela okuphuculweyo, amandla aguquguqukayo, ukugcinwa kwamanzi, ukusebenza, ukuqina, kunye nokuchasana nokushwabana, ukuqhekeka, kunye nezinto ezisingqongileyo.Ezi zongezelelo zenza i-RPP-modified mortars ilungele uluhlu olubanzi lwezicelo zokwakha, kubandakanywa ukufakwa kwe-tile, i-stucco kunye ne-plastering, ukulungiswa nokubuyisela, kunye nokukhusela amanzi.
