Umgubo wepolymer ophinda uhlakazwe (RDP)sesinye sezongezo eziyimfuneko nezibalulekileyo kwiinkqubo zanamhlanje zodaka oluxutyiweyo, ngakumbi kwii-adhesives zethayile. Yipolymer ephilayo eguqula i-emulsion ibe ngumgubo ngokusebenzisa inkqubo yokumisa isitshizi. Ine-redispersibility entle kwaye inokwenza kwakhona i-emulsion ezinzileyo emva kokuxubana namanzi, ngaloo ndlela inika udaka iipropati ezigqwesileyo zokudibanisa, ukuguquguquka kunye nokusebenza kolwakhiwo.
1. Indlela yokwenza i-RDP kwi-adhesive tile
I-adhesive ye-tile yimveliso yodaka eyomileyo esetyenziselwa ukudibanisa iileyile kumphezulu wesiseko, ngokukodwa ihlanganiswe nesamente, i-aggregate edibeneyo, i-thickener, izongezo ze-polymer, njl. Indlela yokusebenza kwayo ngolu hlobo lulandelayo:
1.1. Ukomelezwa kwamandla okudibanisa
Ifilimu ye-polymer eyenziwe yi-RDP emva kwe-hydration ingangena kwi-microporous structure yesiseko ukwenza i-mechanical bite, kunye nokudibanisa kunye nemveliso ye-samente ye-hydration ukunyusa amandla okudibanisa phakathi kwe-tile yokunamathela kunye neetayile kunye nesiseko sesiseko.
2.1. Ukuphucula ukuguquguquka
Ifilimu ye-polymer inokuguquguquka okulungileyo kwaye inokuthatha ngokufanelekileyo uxinzelelo olubangelwa ukwanda kwe-thermal kunye nokunciphisa okanye ukufuduka okuncinci kwesiseko esisezantsi ukukhusela iileyili ekuqhekekeni okanye ukuwa.
2.3. Ukuphucula ukusebenza kolwakhiwo
I-RDP yandisa ixesha lokusebenza lokunamathelisa iithayile, iphucula ukuthambisa kunye nokuziva kolwakhiwo, kwaye iphucula ukusebenza kakuhle kolwakhiwo.
2.4. Ukuphucula ukuxhathisa kokuqhekeka kunye nokunganyanzeki
Ifilimu ye-polymer inokuzalisa i-capillary pores kwi-samente yodaka, ukunciphisa i-porosity, kunye nokuphucula ukuxhathisa ukuqhekeka kunye nokungagungqi.
2.5. Ukuphucula ukuqina kunye nokumelana namanzi
I-RDP iphakamisa ukuchasana kwenkqubo yodaka kwindawo yangaphandle (njengomswakama, ukushisa okuphezulu, i-freeze-thaw, njl.) kunye nokwandisa ubomi benkonzo ye-adhesive tile.
2. Iinzuzo zokusebenza kweRDP
Ukusetyenziswa kwe-RDP ekuqulunqweni kwe-adhesive tile kunezi nzuzo zilandelayo:
Amandla okudibanisa okuphakamileyo: kuphucula kakhulu amandla okubambisana okunamathela kwi-tile yokunamathela kwiitayili (kubandakanywa iileyile eziqiniweyo, iileyile ezipholisiweyo, njl.), kwaye zilungelelanise kwiindawo ezahlukeneyo zesiseko.
Ukuziqhelanisa neemeko ezahlukeneyo: I-RDP inika i-tile yokuncamathelisa ukuchasana kwamanzi okulungileyo, ukuxhathisa ukunyibilika komkhenkce, kunye nokumelana nokwaluphala, kwaye ilungele iindawo ezahlukeneyo zokwakha zangaphakathi nangaphandle.
Ukuguquguquka okunamandla: Kufanelekile kwiimeko ezifunwa kakhulu ezifana nokwakhiwa komgangatho obhityileyo, iithayile ezinobungakanani obukhulu, kunye neethayile eludongeni.
Ikhuseleke kwendalo kwaye ikhuselekile: I-RDP yinto engenatyhefu kwaye ayinavumba kwaye ihlangabezana neemfuno zokhuseleko lokusingqongileyo kwizinto zokwakha eziluhlaza.
3. Idosi ecetyiswayo kunye nesalathiso sefomula
Isixa esicetyiswayo se-RDP kufuneka simiselwe ngokwenqanaba lokusebenza, imeko yesicelo kunye nenkqubo yefomula yokuncamathelisa iithayile. Uluhlu ngokubanzi lulandelayo:
I-adhesive ye-tile eqhelekileyo (uhlobo lwe-C1): Imali eyongezelelweyo ekhuthazwayo yi-1.5% ~ 3% yobunzima obupheleleyo be-glue powder.
I-adhesive ye-tile ye-high-performance adhesive (uhlobo lwe-C2): Imali eyongezelelweyo ekhuthazwayo yi-3% ~ 6%, okanye nangaphezulu.
I-adhesive tile adhesive (uhlobo lwe-S1 / S2): Imali eyongezelelweyo ingaba phezulu njenge-6% ~ 10% ukuphucula ukuguquguquka kunye nomthamo wokufuduka.
Ifomula yereferensi (umzekelo wokuncamathelisa kwethayile kwibakala le-C2):
Isamente yasePortland eqhelekileyo: 40%
Isanti yequartz (0.1-0.3mm): 50%
I-RDP: 4%
HPMC: 0.3%
I-Anti-slip agent: 0.1%
I-Defoamer: imali efanelekileyo
I-arhente yokugcina amanzi / ezinye izongezo: ukulungiswa kakuhle ngokweemfuno
4. Iintlobo zeetayile ezisebenzayo kunye neemeko ze-substrate
I-adhesive yethayile eguqulwe nge-RDP ifanelekile kwiindidi ezahlukeneyo zeethayile kunye ne-substrates, kubandakanywa kodwa kungaphelelanga apho:
Iindidi zeethayile: iithayile ezikhazimlisiweyo, iithayile ezikhazimlisiweyo, iithayile ezigcotyiweyo, iimosaics, ilitye lebhastile, amatye enziweyo, njl.
Iintlobo ze-Substrate: isiseko sodaka lwesamente, ibhodi yesamente, ibhodi yegypsum, isiseko se-tile esidala, ibhodi yekhonkrithi, njl.
I-adhesive ye-tile eguqulwayo kunye ne-RDP ifaneleke ngokukodwa ekufakweni kweetayile zokufunxa amanzi aphantsi kunye neetayile ezinobungakanani obukhulu, obunokusombulula ngokufanelekileyo ingxaki yokungabikho ngokwaneleyo kokuqina kokuqina kodaka lwesamente yendabuko.
5. Izilumkiso
Ngexesha lokwenziwa kwemveliso kunye nenkqubo yesicelo, la manqaku alandelayo kufuneka aqatshelwe:
Khetha uhlobo olufanelekileyo lwe-RDP (njenge-ethylene-vinyl acetate copolymer EVA, i-acrylic polymer, njl.) ukuhlangabezana neemfuno ezahlukeneyo zokusebenza.
Gcina womile ngexesha lokugcina ukuphepha ukufuma kunye ne-agglomeration.
Musa ukugcina izinto ezine-alkaline kakhulu ixesha elide ukukhusela ukusebenza kuchaphazeleka.
Hlanganisa ngokulinganayo ukuphepha ukusabalalisa ngokungafaniyo kwee powders ezikhokelela ekusebenzeni okungazinzanga.
Njengeyona nto ingundoqo yokusebenza kwi-adhesives ye-tile, i-polymer powders e-dispersible iphucula kakhulu amandla okudibanisa, ukuguquguquka kunye nokuqina kwe-adhesives ye-tile, ukuhlangabezana neemfuno zezakhiwo zanamhlanje zokwenza izinto eziphezulu ze-tile. Kwixesha elizayo, kunye nophuhliso lokwakha ushishino, iukusetyenziswa kwe-RDP kwii-adhesives zethayile kunye neemveliso zodaka ezinomxube owomileyoiya kuba yanda ngakumbi, kwaye ukusebenza kwayo kunye neenzuzo zokusingqongileyo kuya kuqhubeka nokukhuthaza ushishino lwezinto zokwakha ukuya kwinqanaba eliphezulu.
