Ezakhiweni zokunamathela ngethayela,i-polymer powder ephinde ihlakazeke (RDP)iyisengezo esibalulekile se-polymer esingokwemvelo. Indima yaso inquma ngqo izakhiwo zokubopha ze-adhesive, ukuguquguquka, kanye nokuqina. I-adhesive yethayela, umkhiqizo ovamile wodaka oxutshwe okomile ekwakheni, isetshenziswa kakhulu ukubopha izinto zokuqeda ezifana ne-ceramics, amathayili e-vitrified, kanye ne-marble. Ukuthembela kuphela emikhiqizweni yokumanzisa yesamente kuvame ukwehluleka ukuhlangabezana namandla nokuqina kwe-bond adingekayo. Ngakho-ke, ukwengezwa kwe-RDP akugcini nje ngokuthuthukisa izakhiwo zomzimba ze-adhesives ezisekelwe kusimende kodwa futhi kuthuthukisa kakhulu ukusetshenziswa kwazo kanye nokusebenza kwesikhathi eside.
1. Ukuthuthukisa Amandla Esibopho
Izinamathiseli zamathayili zidinga i-tick ephezulu yokuqala kanye namandla e-bond yesikhathi eside ukuqinisekisa ukunamathela okuqinile kwamathayili ku-substrate. Ngesikhathi senqubo yokumanzisa nokuqinisa, i-RDP yakha ifilimu ye-polymer efanayo ye-organic engena futhi igoqe phakathi kwemikhiqizo yokumanzisa usimende kanye nama-filler, igcwalisa ama-pores futhi iqinise ukubopha kwe-interfacial. "Isakhiwo esihlanganisiwe se-inorganic-organic" esakhiwe ngezihlanganisi ze-inorganic ezisekelwe kusimende siqinisa ukubopha phakathi kwamathayili kanye ne-substrate. Lokhu kusebenza kakhulu lapho unamathisela amathayili e-vitrified angenawo amanzi amaningi noma amathayili amakhulu.
2. Ukuguquguquka Okuthuthukisiwe Nokumelana Nokuqhekeka
Izintambo zezibopho zesamente zendabuko ziyaphuka futhi ziyaqhekeka ngenxa yokushintshashintsha kwezinga lokushisa kanye nokuguquguquka kwe-substrate. I-polymer eku-RDP yakha ifilimu, enikeza ukuguquguquka kanye nokunwebeka kwe-adhesive yethayela. Lapho i-substrate ishintsha kancane, i-adhesive layer buffers iyacindezela, ivimbele ukuqhekeka. Lokhu kubaluleke kakhulu ekusetshenzisweni kwangaphandle, amathayela amakhulu, noma izinhlelo zokushisa phansi, ezivame ukwanda nokuncipha kokushisa.
3. Ukumelana Okuthuthukisiwe Kwamanzi Nokumelana Nokuqandisa
Izinamathiseli zamathayili zivame ukusetshenziswa ezindaweni ezinomswakama noma ezindaweni ezinamazinga okushisa ashintshashintshayo, njengezindlu zangasese, amakhishi, kanye nezakhiwo zangaphandle. Ngenkathi izinamathiseli ezihlanzekile ezisekelwe kusimende zingalahlekelwa amandla noma zize zigaye uma zivezwa emanzini, isakhiwo se-RDP esakha ifilimu sinciphisa kakhulu ukungena kwamanzi, sithuthukisa ukusebenza kahle kokuvimbela amanzi. I-RDP iphinde ithuthukise ukumelana nokuqandisa kwamathayili. Ngisho nangemijikelezo ephindaphindwayo yokuqandisa, ungqimba lwezinamathiseli lugcina isakhiwo esizinzile kanye nokunamathela, lwandisa impilo yenkonzo yokuqedwa kwamathayili.
4. Ukusebenza Okuthuthukisiwe Kwesicelo
I-RDP ayigcini nje ngokuthuthukisa izakhiwo zemishini zezinamathiseli zamathayili kodwa futhi ithuthukisa ulwazi lokusetshenziswa. Ukusabalala kwayo kwezinhlayiya kuqinisekisa ukuthambisa okungcono kanye nokugcinwa kwamanzi ngemva kokuxuba, kwandise isikhathi sokusebenza futhi kuvumela abafaki isikhathi esengeziwe sokulungisa nokubeka amathayili. I-RDP iphinde ithuthukise ukusebenza kahle kanye ne-thixotropy yezinamathiseli zamathayili, okwenza kube lula ukuzisebenzisa futhi kunciphise ingozi yokugoba nokuqhekeka.
5. Ukuqina Okuthuthukisiwe Nokuzivumelanisa Nezimo
Ukusebenza kwesikhathi eside kwezinamathiseli zamathayili kuncike kakhulu ekuzivumelaniseni kwazo nezinguquko zemvelo. I-RDP inikeza ukumelana okuhle kakhulu nesimo sezulu, ukumelana ne-alkali, nokuguga, igcina ukusebenza okuzinzile ngisho nangaphansi kokuchayeka kwe-UV, ukushintshashintsha komswakama, kanye nezindawo ezine-acidic ne-alkali. Ngaphezu kwalokho, izinamathiseli zamathayili eziguquliwe yi-RDP zifaneleka kakhulu ezinhlotsheni ezahlukahlukene ze-substrate, njengekhonkrithi, ibhodi le-gypsum, kanye nodaka lwesamente, okwandisa ububanzi bazo bokusetshenziswa.
6. Ukubaluleka Kwezemvelo Nokonga Amandla
Ngokuthuthuka kwezakhiwo eziluhlaza, izinamathiseli zamathayili zithatha indawo kancane kancane yezindlela zokufaka udaka lukasimende lwendabuko. Ukusetshenziswa kwe-RDP kwenza izinamathiseli zamathayili zifinyelele ukubopha okuhle kakhulu ngezimbozo ezincane, kunciphisa kakhulu ukusetshenziswa kwezinto futhi kudalwe inqubo yokwakha ehlanzekile nenobungani nemvelo. Lokhu akugcini nje ngokunciphisa ukusetshenziswa kwamandla nezindleko kodwa futhi kuhambisana nezitayela zokonga amandla nezingabungani nemvelo zokwakha zanamuhla.
Indima eyinhloko ye-RDP kuma-adhesive amathayiliiwukuthuthukisa amandla ezibopho, ukuthuthukisa ukuguquguquka nokumelana nokuqhekeka, ukuthuthukisa ukumelana namanzi nokuqandisa, ukuthuthukisa ukusebenza kahle, nokuthuthukisa ukuqina kanye nobungane bemvelo. Ngokwakha isakhiwo esihlanganisiwe ngemikhiqizo yokumanzisa usimende, kuthuthukisa kakhulu ukusebenza okuphelele kwezinamathiselo zamathayili, okuzivumela ukuthi zihlangabezane nezidingo zokwakha ezinamandla aphezulu, ezinkulu, neziyinkimbinkimbi zezakhiwo zesimanje. Ngakho-ke, i-RDP isibe yingxenye ebalulekile ebalulekile ekwakhiweni kwezinamathiselo zamathayili.
