Yini i-polymer polymer powder?

1. Isingeniso se-polymer powder (RDP)

I-polymer polymer powder(I-RDP) iyinto ehlukahlukene yokwakha etholakala kuma-polymer emulsions ngokusebenzisa eyomile yokufafaza. Lapho kuxutshwe namanzi, i-RDP iphinda ingene ku-latex, inikezela ngezimpawu zokusebenza ezifanayo njengokuhlakazeka kwasekuqaleni. Kuthuthukisa ukunamathela, ukuguquguquka, ukumelana kwamanzi, nokuqina kokuqina kwezinto zokwenziwa ngo-cementizer ne-gypsum.

I-RDP yakhiwa ngokuyinhloko ngeVinyl Acetate Ethylene (VAE), acryren, noma i-styrerene-buthadiene copolymers. Izakhiwo zayo zenza kufezeke ekwakhiweni kwesimanje ukukhiqiza ukusebenza okuphezulungc-mixUDotars, anamathela ngamathayi, kanye nezinhlelo zokuqeda ukungena kwezinga (ama-EIF).

2. Inqubo Yokukhiqiza

Ukukhiqizwa kwe-RDP kubandakanya lezi zinyathelo ezilandelayo:

1. Ukukhiqizwa kwe-polymer emulsion: Ama-polymers afana ne-vae ahlanganiswe nge-emulsion polymerization.
2. Ukuhlanganiswa okungeziwe: Ama-colloids avikelayo (isib., I-polyvinyl alcohol) kanye nama-anti-casiking agents (isib.
3. Spray eyomile: I-polymer emulsion iyomiswa isifutho ukuze ihlele i-powder egeleza mahhala.
4. Ukuwowapha: I-powder ifakwe ezitsheni ezingavikeleki komswakama ukuze ilondoloze izakhiwo zayo.

3. Izinhlobo kanye nokwakheka kwamakhemikhali

I-RDP iyahlukahluka ngokuya ngohlobo lwe-polymer kanye nezithasikhali zamakhemikhali ezisetshenzisiwe. Ithebula elilandelayo libonisa izinhlobo ezijwayelekile kanye nezimpawu zazo zokuqala:

Izithasiselo:

• Ukuvikela ama-colloids: I-polyvinyl alcohol iqinisekisa ukubuyiselwa kabusha.
• Ama-Age-Caking Agents: USilica uvimbela ukuqina.

4. Izakhiwo nezinzuzo

I-RDP ithuthukisa izinto zokwakha ngokudlulisela le ndawo elandelayo:

Izakhiwo zemishini

• Ukuvumelana nezimo: Yehlisa ukuqhekeka emikhiqizweni esekwe kuthusi.
• Ukunamathela: Kuthuthukisa ukubopha izibopho ezindaweni ezahlukahlukene.
• Amandla asheshayo: Kwandisa ukumelana namandla angaphandle.

Izakhiwo Ezibonakalayo

• Ukugcinwa kwamanzi: Ibambezela ukuphuma kwamanzi, ukuthuthukisa i-hydration.
• Ukusebenza: Kusiza uhlelo lokusebenza olulula kanye nokuqedwa okubushelelezi.
• Ukuqina: Ithuthukisa ukumelana nokuvimbela isimo sezulu kanye nokuqhakaza imijikelezo.

I-5. Izicelo kuzo zonke izimboni

I-RDP ithola izinhlelo zokusebenza emikhakheni ehlukahlukene, ikakhulukazi ukwakhiwa.

Izinto zokwakha

• Izinamathiseli nama-ry: Iqinisekisa ukunqwabelana okuqinile nokumelana nokuqhekeka.
• Amakhompiyutha Wokuzindla: Kuthuthukisa izindawo zokugeleza kanye nokuqedwa komhlaba.
• Ama-plasters kanye nama-render: Kuthuthukisa ukusebenza nokuqina.

Izinhlelo zokufakelwa

• Ama-EIFS (amasistimu wokuqeda ukungena ngaphakathi kwangaphandle): Inikeza ukuguquguquka nokunamathelisa.

Izixazululo ezingangeni manzi

• Ukumboza kanye nolwelwesi: Kuthuthukisa ukumelana kwamanzi nokubhuka kwe-crack.

Ukulungisa udaka

• Ukulungiswa kwesakhiwo: Kuthuthukisa amandla omshini wokubuyiselwa emsebenzini.

Ithebula: Izicelo nomthelela wokusebenza

6. Izici zokusebenza kwezinto zokwakha

Igalelo le-RDP ezintweni zokwakha lingahlaziywa ngomthelela walo kumamethrikhi asemqoka.

6.1 Ukunamathela nokuhlangana

• I-RDP ikhulisa amandla ebhondi olwa nezindawo ezahlukahlukene ezingezansi, kufaka phakathi ukhonkolo, izinkuni kanye nensimbi.

6.2 Ukugcinwa kwamanzi

• Ukugcinwa kwamanzi okuthuthukile kusekela i-hyment engcono yokusebenza nokusebenza.

6.3 Ukuqhekeka Kwe-Crack

• Ukuqina okunikezwe yi-RDP kuvimbela imifantu ngenxa yokuxineka okushisayo nokwenziwe ngomshini.

Ukuhlaziywa kokuqhathanisa kodaka nge-RDP

7. Izitayela zemakethe kanye nezinto ezintsha

Imakethe ye-RDP yomhlaba wonke iyakhula, iqhutshwa ngokungezelela ukufunwa kwezinto zokwakha ezisebenza kahle neziqinile. Izitayela ezibalulekile zifaka:

• Imikhiqizo eco-enobungane: Ukuthuthukiswa kwe-RDP nge-VOC ephansi
• Izakhi ezithuthukile: Ukusungulwa okusha ezikwakhisweni ze-copolymer ukusebenza okuthuthukile.
• Isidingo esikhuphukayo ezimakethe ezivelayo: Ukukhula kwengqalasizinda e-Asia-Pacific ukukhulisa imfuno.

Ithebula: Ukuqagelwa kokukhula kwemakethe yomhlaba wonke

8. Izinselelo kanye nokulinganiselwa

Naphezu kwezinzuzo zayo, i-RDP inokulinganiselwa okuthile:

• Ukuzwela komswakama: Kudinga ukupakishwa okuvimbela umswakama.
• Izindleko: I-RDP ephezulu kakhulu ingakhuphula izindleko zephrojekthi.
• Umthelela wezemvelo: Ukukhishwa kwe-VOC, yize kuncishisiwe ekuhlukahlukani kwesimanje.

I-PolyMer Powder evuselelayo iyingxenye ebaluleke kakhulu ezintweni zesimanje zokwakha, enikeza ukusebenza okuthuthukisiwe ngokunamanzi okuthuthukile, ukuguquguquka nokumelana kwamanzi. Ukuvuselelwa okuqhubekayo kanye nokucindezela komhlaba wezinto zokwakha ezizinzile kulindeleke ukuthi kuphinde kwamukelwe ukwamukelwa kwe-Advanced RDP. Njengoba izimboni zibeka phambili ukusebenza, ukuqina, kanye nokusimama kwemvelo, i-RDP izoqhubeka nokudlala indima ebalulekile ekwakheni ikusasa lezinto zokwakha.
