Kwimixube yokuncamathelisa iithayile,umgubo wepolymer ophinda unyibilike (RDP)sisithako esibalulekileyo se-polymer esiphilayo. Indima yaso imisela ngokuthe ngqo iimpawu zokubopha ze-adhesive, ukuguquguquka, kunye nokuqina. I-adhesive yethayile, imveliso eqhelekileyo yodaka oluxutywe nodaka ekwakhiweni, isetyenziselwa kakhulu ukubopha izinto zokugqiba ezifana ne-ceramics, iithayile ze-vitrified, kunye ne-marble. Ukuthembela kuphela kwiimveliso zokufunxa isamente kudla ngokungaphumeleli ukuhlangabezana namandla kunye nokuqina kwe-bond efunekayo. Ke ngoko, ukongezwa kwe-RDP akuphuculi kuphela iimpawu zomzimba ze-adhesives ezisekelwe kwisamente kodwa kuphucula kakhulu ukusetyenziswa kwazo kunye nokusebenza kwazo ixesha elide.
1. Ukuphucula Amandla eBond
Izincamathelisi zethayile zifuna i-tick yokuqala ephezulu kunye namandla e-bond yexesha elide ukuqinisekisa ukunamathela okuqinileyo kwethayile kwi-substrate. Ngexesha lenkqubo yokufunxa nokuqinisa, i-RDP yenza ifilimu ye-polymer efanayo ye-organic engena kwaye igubungele phakathi kweemveliso zokufunxa isamente kunye nezizalisi, igcwalisa iimbobo kwaye iqinise ukubophelelana phakathi kwe-interfacial. "Isakhiwo se-inorganic-organic composite" esenziwe ngee-inorganic binders ezisekelwe kwisamente siqinisa ukubophelelana phakathi kwethayile kunye ne-substrate. Oku kusebenza ngakumbi xa kuncamathiselwa iithayile ezi-vitrified ezifunxa amanzi amancinci okanye iithayile ezinkulu.
2. Ukuphuculwa kokuguquguquka kunye nokumelana nokuqhekeka
Imigca yesamente yesiqhelo yokubopha i-samente ibuthathaka kwaye isengozini yokuqhekeka ngenxa yokuguquguquka kobushushu kunye nokuguquguquka kwe-substrate. I-polymer kwi-RDP yenza ifilimu, inika ukuguquguquka kunye nokuthamba kwi-adhesive yethayile. Xa i-substrate iguquka kancinci, i-adhesive layer buffers iyaxinzelela, ithintele ukuqhekeka. Oku kubaluleke kakhulu kwizicelo zangaphandle, iithayile ezinkulu, okanye iinkqubo zokufudumeza umgangatho, ezinokuthi zande kwaye zinciphe ngobushushu.
3. Ukumelana Okuphuculweyo Kwamanzi kunye Nokumelana Nokuqandeka Komkhenkce
Izincamathelisi zethayile zihlala zisetyenziswa kwiindawo ezifumileyo okanye kwiindawo ezinamaqondo obushushu atshintshatshintshayo, njengezindlu zangasese, iikhitshi, kunye neefacade zangaphandle. Nangona izibopheleli ezisekelwe kwisamente zinokulahlekelwa ngamandla okanye zicolwe xa zichatshazelwe ngamanzi, ulwakhiwo lwe-RDP olwenza ifilimu lunciphisa kakhulu ukungena kwamanzi, nto leyo ephucula ukusebenza kakuhle kokuthintela amanzi ukuba angangeni. I-RDP ikwaphucula ukumelana nokuqandisa kwezincamathelisi zethayile. Nokuba kukwimijikelo yokuqandisa ephindaphindwayo, umaleko wokuncamathelisa ugcina ulwakhiwo oluzinzileyo kunye nokunamathela, nto leyo eyandisa ubomi benkonzo yokugqitywa kwezi thayile.
4. Ukusebenza okuPhuculweyo kweSicelo
I-RDP ayigcini nje ngokuphucula iimpawu zoomatshini zezincamathelisi zethayile kodwa ikwaphucula amava okusetyenziswa. Ukusasazeka kwayo kwamasuntswana kuqinisekisa ukuthambisa okungcono kunye nokugcinwa kwamanzi emva kokuxuba, kwandisa ixesha lokuvula kwaye kuvumela abafaki ixesha elingakumbi lokulungisa nokubeka iithayile. I-RDP ikwaphucula ukusebenza kakuhle kunye ne-thixotropy yezincamathelisi zethayile, okwenza kube lula ukuzisebenzisa kwaye kunciphisa umngcipheko wokuqhekeka nokuqhekeka.
5. Ukuqina Okuphuculweyo kunye Nokuziqhelanisa Neemeko
Ukusebenza kwexesha elide kwezincamathelisi zethayile kuxhomekeke kakhulu ekuzivumelaniseni kwazo notshintsho lwendalo. I-RDP inika ukumelana okuhle kakhulu nemozulu, i-alkali, kunye nokwaluphala, igcina ukusebenza okuzinzileyo nokuba phantsi kokuvezwa yi-UV, ukuguquguquka komswakama, kunye neendawo ezine-asidi kunye ne-alkaline. Ngaphezu koko, izincamathelisi zethayile eziguqulwe yi-RDP zifanelekile ngakumbi kwiintlobo ngeentlobo zezinto ezisetyenziswayo, ezifana nekhonkrithi, ibhodi ye-gypsum, kunye nodaka lwesamente, nto leyo eyandisa uluhlu lwazo lokusetyenziswa.
6. Ukubaluleka kokusingqongileyo nokonga amandla
Ngophuhliso lwezakhiwo eziluhlaza, izincamathelisi zeethayile zithatha indawo yeendlela zemveli zokufakela udaka lwesamente. Ukusetyenziswa kwe-RDP kwenza izincamathelisi zeethayile zifikelele ekubopheni okufanelekileyo ngeengubo ezincinci, kunciphisa kakhulu ukusetyenziswa kwezinto kwaye kudala inkqubo yokwakha ecocekileyo nenobuhlobo nokusingqongileyo. Oku akunciphisi nje kuphela ukusetyenziswa kwamandla kunye neendleko kodwa kuhambelana neendlela zokonga amandla kunye nobuhlobo nokusingqongileyo zokwakha zanamhlanje.
Indima ephambili ye-RDP kwi-adhesives zethayilekukuphucula amandla e-bond, ukuphucula ukuguquguquka kunye nokumelana nokuqhekeka, ukuphucula ukumelana namanzi kunye nokunyibilika komkhenkce, ukuphucula ukusebenza kakuhle, kunye nokuphucula ukuqina kunye nobuhlobo nokusingqongileyo. Ngokwenza isakhiwo esidibeneyo ngeemveliso zokufunxa isamente, kuphucula kakhulu ukusebenza ngokubanzi kwee-adhesive zethayile, okuzivumela ukuba zihlangabezane neemfuno zokwakha ezinamandla aphezulu, ezinkulu, nezintsonkothileyo zezakhiwo zanamhlanje. Ke ngoko, i-RDP ibe yinxalenye ebalulekileyo ebalulekileyo kwi-formulations ye-adhesive yethayile.
