I-redispersible latex powder, eyaziwa nangokuthi i-polymer powder ehlakazeka kabusha noma i-RDP, iyisithako esibalulekile ezintweni zokwakha zesimanje, ikakhulukazi emkhakheni wodaka oluxubene elomile.Lezi zimpushana zisetshenziswa kakhulu ezimbonini ezehlukene ezihlanganisa ezokwakha, upende nezingubo zokuhlanganisa, izinto zokunamathisela, izindwangu kanye nemithi, phakathi kokunye.
1. Isingeniso sempushana ye-latex ehlakazeka kabusha:
I-latex powder e-redispersible iyimpushana ye-polymer egeleza mahhala etholakala ngokumiswa kokufuthwa kokuhlakazeka kwe-polymer enamanzi.Iqukethe ingxube yama-polymers okwenziwa, ngokuvamile i-vinyl acetate-ethylene (VAE) copolymer, kanye nezithasiselo ezihlukahlukene ezifana nama-colloid okuzivikela, ama-plasticizers, nama-dispersants.Inhloso eyinhloko ye-latex powder e-redispersible ukuthuthukisa ukusebenza kwezinto zokwakha, ukunikeza izakhiwo ezibalulekile ezifana nokunamathela, ukuguquguquka, ukumelana kwamanzi nokucutshungulwa.
2. Inqubo yokukhiqiza:
Ukukhiqizwa kwe-latex powder ehlakazeka kabusha kuhilela izinyathelo ezimbalwa ezibalulekile:
A. i-polymerization:
Inqubo iqala nge-emulsion polymerization yama-monomers afana ne-vinyl acetate ne-ethylene phambi kwabaqalisi kanye nama-surfactants.Lesi sinyathelo sikhiqiza ukuhlakazeka okunamanzi kwezinhlayiya ze-polymer.
b.Ukomisa isifutho:
I-aqueous dispersion bese yomiswa, ifakwe i-athomu ibe amaconsi futhi yomiswe ngokushesha kusetshenziswa umoya oshisayo.Impushana ewumphumela iqukethe izinhlayiya ze-polymer ezincane ezimbozwe nge-colloid evikelayo.
C. Ngemuva kokucubungula:
Ngemuva kwalokho izinqubo zokucubungula zingase zenziwe ukuze kuthuthukiswe izakhiwo zempushana.Lokhu kungase kuhlanganise ukomiswa okwengeziwe, ukuguqulwa kwendawo noma ukwengeza izithasiselo.
3. Ukwakhiwa:
I-latex powder ephinda ihlakazeka ngokuvamile iqukethe izithako ezilandelayo:
I-Polymer adhesive: Isithako esiyinhloko ngokuvamile i-copolymer ye-vinyl acetate ne-ethylene, ehlinzeka ngezakhiwo zokwakha ifilimu nokunamathela.
Ama-colloid avikelayo: Lezi zinto zivimbela ukuhlangana kwezinhlayiya ze-polymer ngesikhathi sokugcina futhi ziqinisekisa ukuphinda kuhlakazeka okuhle.
Ama-Plasticizers: Thuthukisa ukuguquguquka nokuguquguquka komkhiqizo wokugcina.
Ama-Dispersants: Siza izimpushana zihlakazeke emanzini futhi zenze kube lula ukuhlanganiswa kwazo zibe amafomula.
4. Ukusebenza nokusebenza:
I-latex powder ehlakazeka kabusha idlulisela izici ezimbalwa ezibalulekile ezintweni zokwakha, okuhlanganisa:
Ukunamathela: Kuthuthukisa amandla ebhondi, ikakhulukazi odakeni kanye nezinamatheliso zamathayela.
Ukuvumelana nezimo: Kuthuthukisa ukumelana nokuqhekeka kanye nokuguqulwa, okubalulekile kuma-membrane okuvimbela amanzi aguquguqukayo kanye ne-caulk.
Ukumelana Namanzi: Inikeza isivikelo kumswakama futhi ithuthukisa ukuqina ezindaweni ezimanzi.
Ukucutshungulwa: Kuthuthukisa ukuphatha kanye nezici zokusetshenziswa kokwakheka kwengxube eyomile.
5. Isicelo:
Redispersible latex powder isetshenziswa kabanzi ezimbonini ezahlukahlukene:
a.Bekezela:
I-Tile Adhesives kanye namaGrouts: Thuthukisa ukunamathela nokuvumelana nezimo ekufakweni kwamathayili.
I-Exterior Insulation and Finishing Systems (EIFS): Thuthukisa ukusebenza kwe-EIFS ngokunikeza ukuguquguquka nokumelana nokuqhekeka.
Udaka nokhonkolo: Thuthukisa amandla okubopha, ukusebenza kanye nokungazweli kwamanzi odakeni lukasimende namapulasi.
I-self-leveling Compound: Ithuthukisa ukugeleza nokunamathela kwezinhlanganisela zokuzilinganisa phansi.
b.Amapende nama-Coatings:
Isetshenziswa njengefilimu yangaphambili kanye ne-binder kumapende asekelwe emanzini kanye nama-coatings ukuthuthukisa ukunamathela nokuqina.
C. Okunamathelayo:
Ithuthukisa ukunamathela nokubumbana ezinhlotsheni ezihlukahlukene zokunamathela, okuhlanganisa izinto zokunamathisela ngokhuni nezinamatheliso zokwakha.
6. Izinzuzo:
Ukusebenzisa kabusha i-latex powder kunezinzuzo ezilandelayo:
Izakhiwo ezithuthukisiwe: Ithuthukisa izakhiwo ezibalulekile zezinto zokwakha njengokunamathela, ukuguquguquka nokungangeni kwamanzi.
I-Versatility: Ifanele uhla olubanzi lwezinhlelo zokusebenza kusukela odakeni nama-adhesives kuya kumapende nama-coatings.
Ukuphatha kalula: Njengempushana eyomile, kulula ukuyihambisa, ukuyigcina nokubamba, vele ungeze amanzi ukuze uhlakaze kabusha.
Ubungane bemvelo: Amafomula asekelwe emanzini ahambisana kakhulu nemvelo kunezinye izindlela ezisekelwe ku-solvent.
Ukusebenza Kwezindleko: Kusiza ukuthuthukisa ukwakheka, ukwehlisa izindleko zezinto ezibonakalayo, nokuthuthukisa ukusebenza komkhiqizo.
7. I-Outlook Yesikhathi esizayo:
Imakethe yempuphu ye-latex ehlakazeka kabusha kulindeleke ukuthi ifakazele ukukhula okuqhubekayo, okuqhutshwa ukuthuthukiswa kwengqalasizinda okuqhubekayo, ukufudukela emadolobheni, kanye nesidingo esikhulayo sezinto zokwakha ezisebenza kahle.Intuthuko yezobuchwepheshe okuhloswe ngayo ukuthuthukisa ukusebenza komkhiqizo kanye nokwandisa izindawo zokufaka izicelo kungenzeka kuqhubekisele phambili ukwanda kwemakethe.Ukwengeza, ukuqwashisa okukhulayo kwezinqubo zokwakha ezisimeme kungase kugqugquzele ukwamukelwa kwezinye izindlela ezingavumelani nemvelo, njengezimpushana ze-latex ezihlakazeka kabusha.
I-latex powder ehlakazeka kabusha idlala indima ebalulekile ekuthuthukiseni ukusebenza kwezinto zokwakha kuzo zonke izimboni ezihlukahlukene.Izakhiwo zayo eziyingqayizivele nokuguquguquka kwayo kuyenza ibaluleke kakhulu ezintweni ezisetshenziswayo kusukela kokunamathelisa amathayela nodaka kuya kupende nama-coatings.Ngokuqhubekayo emisha kanye nokugcizelela okwandayo kwezinqubo zokwakha ezisimeme, isidingo se-latex powder ehlakazeka kabusha kulindeleke ukuthi siqhubeke sikhula, siqhubekisela phambili ucwaningo nentuthuko kule ndawo.
