I-Redispersergeble Powmer Powder (RDP) ingumpuphu ekwakheka ngomishini wokufafaza we-polymer emulsion. Ingashintshwa i-emulsion emanzini ukuze ibuyisele izakhiwo zayo zokuqala, ngakho-ke isetshenziswa kabanzi ekuthuthukisweni kokwakhiwa neminye imikhiqizo yezimboni. Lo mbhalo uzohlola ukusetshenziswa okuhlukahlukene kwe-polymer powder evuselelayo ekuthuthukisweni komkhiqizo wezimboni, kufaka phakathi izinto zokwakha, ukunamathela, ukumboza kanye nama-caulking agents.
1. Izinto zokwakha
Ukusetshenziswa kwe-polymer powder evuselelayo ezintweni zokwakha kungenye yezinkambu ezibanzi kakhulu. Kungathuthukisa ngempumelelo ukusebenza kodaka oluhlanganisiwe, njengokuthuthukisa amandla okuqinisa, ukumelana nokuqina. Kuhlelo lwangaphandle oludongeni lokufakwa kwezithako, i-RDP, njengesiguquli sesendlalelo se-bonding kanye nongqimba olubunjiwe, lungathuthukisa amandla ashukumisayo kanye nokumelana nomthelela wesakhiwo. Ngaphezu kwalokho, i-RDP nayo ingathuthukisa ukumelana kwamanzi kanye nokumelana nesimo sezulu sezinto zokwenziwa kosimende, ukuze kusakwazi ukugcina ukusebenza okuhle ezindaweni ezinokhahlo.
I-RDP nayo isetshenziswa kabanzi ezintweni ezizimele ezingezansi. Izitezi zokuzimela zidinga uketshezi oluhle namandla athile. Ukungezwa kwe-RDP kungathuthukisa ukusebenza kokwakha kwezinto zokwakha ukuzimela, zithuthukise amandla abo acindezelayo namafuzo, futhi ngaleyo ndlela kuqinisekiswe ukuthi kuhlale nokuqina phansi. Ezinhlosweni ze-tile, ukusetshenziswa kwe-RDP nakho kubaluleke kakhulu. Kungathuthukisa ukunamathela kokuqala kanye namandla okugcina ama-adhesives tile, kwandise izakhiwo ezi-anti-slip, futhi ngaleyo ndlela kuqinisekiswe ukuqina kwamathayili kanye nokwakha lula ukwakhiwa.
2. Adshesives
I-Redisperible Polymer powder isetshenziswa kabanzi ekunamathisweni, ikakhulukazi ezinhlangeni zezinkuni namapheshana anamathela. I-glue yendabuko yendabuko ivame ukuba brittle ngemuva kokuphuma kwamanzi, kuyilapho i-RDP ingathuthukisa ukuguquguquka kanye nokumelana nokuqhekeka kokulinganiselwa kokunamathela futhi kunwebe impilo yabo yenkonzo. Ngasikhathi sinye, i-RDP nayo ingathuthukisa amandla eBonding of Adhesives, ibenze balungele ukubopha izibopho phakathi kwezinto zokwakha, njlwi, indwangu, isikhumba esivame ukusetshenziswa kwimikhiqizo enjengemikhiqizo enjengezinkuni ezifana nokuqinisa ukuqina kwazo kanye nokusebenza.
3. I-Coatings
Embonini yezambatho, i-polymerble powder evuselelayo ingathuthukisa kakhulu ukusebenza kwezimbozo. I-RDP ingathuthukisa ukunamathela kwezimbozo futhi ibenze bagqoke kakhulu futhi bavimbela amanzi. Ngaphezu kwalokho, i-RDP nayo ingathuthukisa ukuguquguquka kwezimbozo futhi inciphise ingozi yokuqhekeka. Le mpahla yenza i-RDP ibe yisengezo esifanelekile sokuqalwa kodonga lwangaphandle oluphezulu, izimbobo zokunwebeka kanye nezingubo zokumboza amanzi. I-polymer polymerble powder ingahle isetshenziswe njengezengezo ezimbozweni zaphansi ukuze zithuthukise ukumelana nokugqokwa nokuphikiswa kokugqwala kwamakhemikhali phansi, ngaleyo ndlela kunwebe impilo yayo yenkonzo.
Ukusetshenziswa kwe-RDP ku-Powder Coathings nakho kuyanda kancane kancane. Uma kuqhathaniswa nezimbozo ezisuselwa kwiSolvent, izigqoko zempuphu zinobungane ngokwemvelo, futhi ukungezwa kwe-RDP kungathuthukisa ububi kanye nezakhiwo ezenziwe ngefilimu ze-powder coathings, ukuze zinikeze ukumboza okuhle nokunamathela ku-substrate ehlukile. Lokhu kwenza i-RDP ibe nesikhundla esibalulekile emakethe yemvelo enobungane yemvelo.
4. Sealant
Ukusetshenziswa kwe-polymer powder evuselelayo e-sealant kungathuthukisa kakhulu ukusebenza kwawo. I-Sealant yendabuko ivame ukuqhekeka ngenxa ye-shrinkage ngesikhathi senqubo yokwelapha, kepha ngemuva kokungeza i-RDP, ukumelana nokuqhekeka kanye nokuguquguquka kwe-sealant kuthuthukiswa kakhulu, kunciphisa ubungozi bokuqhekeka. Ngaphezu kwalokho, i-RDP nayo ingathuthukisa amandla eBonding kanye nokumelana kwamanzi kwe-sealant, ukuze kusakwazi ukugcina ukusebenza okuhle endaweni enomswakama. Lokhu kubaluleke kakhulu ekwakhiweni kwe-caulking ezindaweni eziphakeme zomswakama njengezindlu zokugezela namakhishi.
Ku-caulking access ephezulu ye-caulking, i-RDP nayo ingabanika izakhiwo ezi-anti-fouling and antibacterial, iqinisekise ukuthi ama-caulking agents ahlala emuhle futhi ahlanzekile ngesikhathi sokusebenzisa isikhathi eside. Lokhu kwenza i-RDP isetshenziswe kabanzi emhlobisweni wezokwakha okuphezulu.
5. Ezinye izinhlelo zokusebenza zezimboni
Ngokungeziwe kulezi zindawo ezingenhla kwezicelo ezingenhla, i-redisperserble poster powder ibuye ikhombise izinzuzo zayo ezihlukile kwamanye amasimu wezimboni. Isibonelo, embonini yezindwangu, i-RDP ingasetshenziswa njenge-ejenti yokuqeda indwangu ukuze ithuthukise ukuthamba nokuhlanzeka kwezindwangu. Embonini yamaphepha ephakethe, i-RDP ingathuthukisa amandla kanye nezindawo ezingaphezulu zephepha futhi zithuthukise imiphumela yokuphrinta. Embonini yePlastics, i-RDP ingasetshenziswa njenge-spitizer kanye ne-modifier ukuthuthukisa ukuguquguquka nokuqina kwamapulasitiki.
Ngenxa yokusebenza kwayo okuhle kakhulu nokusebenza okubanzi, i-polymer powder evuselelayo isibe yinto ebaluleke kakhulu futhi ebalulekile ekwakhiweni kwemikhiqizo yesimanje yezimboni. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokunwetshwa okuqhubekayo kwezinkundla zohlelo lokusebenza, amathemba wesicelo se-RDP embonini azoba abanzi.
