Ifu ya redispersible polymer (RDPs) yakuruye cyane mubikorwa byubwubatsi kubera ubushobozi bwabo bwo kuzamura imitungo itandukanye ya minisiteri nibicuruzwa bishingiye kuri sima.Imwe mu nyungu zingenzi za RDP nubushobozi bwayo bwo kongera imbaraga zo guhangana na sag, ikintu cyingenzi mubikorwa byubwubatsi.
Ifu ya polymer isubirwamo (RDP) yahindutse inyongeramusaruro nyinshi mubikoresho byubwubatsi, itanga inyungu zinyuranye zirimo kunonosora neza, guhinduka, kurwanya amazi no kurwanya sag.Kurwanya Sag bivuga ubushobozi bwibintu kugirango bigumane imiterere yabyo kandi birinde gutembera cyangwa guhinduka iyo bishyizwe hejuru cyangwa hejuru.Mubikorwa byubwubatsi nkibikoresho bya tile, plaster na stucco, kurwanya sag ni ngombwa kugirango habeho kwishyiriraho neza no gukora igihe kirekire.
Ibyiza bya Powder ya Redispersible Polymer (RDP)
Ubusanzwe RDP ikorwa hifashishijwe uburyo bwo kumisha spray aho gukwirakwiza polymer bihinduka ifu yuzuye ubusa.Ibiranga RDP, harimo ingano yubunini, ubushyuhe bwikirahure, ubwoko bwa polymer, nibigize imiti, bigira uruhare runini mukumenya imikorere yabyo mubikorwa byubwubatsi.Ingano yubunini bwa RDP igira ingaruka ku ikwirakwizwa ryayo, gukora firime hamwe nubukanishi, ibyo nabyo bigira ingaruka kumurwanya wa sag.
1.RDP uburyo bwo kunoza imitekerereze irwanya sag
Hariho uburyo bwinshi butanga umusanzu wa RDP mukurwanya kugabanuka:
a.Kuzuza ibice: Ibice byiza bya RDP birashobora kuzuza icyuho no kongera ubwuzure bwuzuye bwa minisiteri cyangwa ibifatika, bityo bikongera imbaraga zo guhangana na sag.
b.Gukora firime: RDP ikora firime ikomeza iyo iyobowe, igashimangira matrix ya mortar kandi igatanga ubumwe, bityo bikagabanya impengamiro yo kugabanuka.
C. Guhinduka: Imiterere ya elastike ya RDP igira uruhare mu guhinduka kwa minisiteri, ikabasha kwihanganira imihangayiko no guhindagurika nta kugabanuka.
d.Kubika amazi: RDP irashobora kunoza ubushobozi bwo gufata amazi ya minisiteri, ikemeza ko ikora igihe kirekire kandi ikagabanya ibyago byo kugabanuka mugihe cyo kubaka.
2. Ibintu bigira ingaruka kumurwanya
Hariho ibintu byinshi bigira ingaruka kumurwanya wibikoresho bya sima, harimo:
a.Ibigize: Ubwoko nubunini bwa RDP, kimwe nibindi byongeweho nkibibyimbye kandi bitatanye, birashobora kugira ingaruka zikomeye kubirwanya sag.
b.Guhuzagurika: Guhoraho kwa minisiteri cyangwa ibifata bigenwa nimpamvu nkikigereranyo cyamazi yifatanije nigikorwa cyo kuvanga, kandi kigira uruhare runini mukurwanya sag.
C. Ibikoresho bya Substrate: Ibiranga substrate, nko gutitira no gukomera, bigira ingaruka kumyifatire no kwihanganira ibintu byakoreshejwe.
d.Ibidukikije: Ubushyuhe, ubushuhe, n’umuyaga birashobora kugira ingaruka kumisha no gukira, bityo bikagira ingaruka kumurwanya.
3. Isuzuma ryo kurwanya sag
Uburyo butandukanye burashobora gukoreshwa mugusuzuma ubukana bwibikoresho byubaka, harimo:
a.Ibizamini bitemba: Ibizamini bitemba, nkibizamini bya slump hamwe nigeragezwa ryintebe, bikoreshwa mugusuzuma imyitwarire yimigendekere hamwe na minisiteri hamwe nibisumizi.
b.Ikizamini cya Sag: Ikizamini cya sag gikubiyemo gukoresha icyitegererezo uhagaritse cyangwa hejuru no gupima urugero rwa sag mugihe.Ubuhanga nko gupima cone no gupima ibyuma bikoreshwa mukugereranya kwihanganira sag.
C. Ibipimo by'imiterere: Ibipimo by'imiterere, harimo ubwiza, guhangayikishwa n'umusaruro hamwe na thixotropy, bitanga ubushishozi ku myitwarire n'imiterere y'ibikoresho by'ubwubatsi.
d.Imikorere ifatika: Ubwanyuma, ibikoresho birwanya sag bisuzumwa hashingiwe kubikorwa byayo mubikorwa nyabyo, nko gushiraho amabati no kwerekana isura.
4. Gushyira mu bikorwa RDP mukuzamura sag
RDP ikoreshwa cyane mubikoresho byubwubatsi kugirango irusheho guhangana na sag:
a.Amatafari ya Tile: RDP itezimbere hamwe na sag irwanya imiti ya tile, igahuza neza kandi ikagabanya kunyerera mugihe cyo kuyishyiraho.
b.Rendering na Stucco: Muri plaster yo hanze na stucco, RDP yongerera imbaraga sag kandi ikanemerera gukora neza, ndetse igashyirwa kumurongo uhagaze nta gusinzira cyangwa guhindura.
C. Kwishyira hamwe-Kwishyira hamwe: RDP irashobora kwinjizwa mubice byo kuringaniza kugirango itezimbere imigendekere no kugabanuka, bikavamo ubuso bunini kandi buringaniye.
d.Amashanyarazi adashobora gukoreshwa n’amazi: RDP yongerera imbaraga imbaraga zo guhangana n’amazi adafite amazi, ikanatanga ubwishingizi kandi ikanarinda amazi meza.
5. Inyigo n'ingero
Ubushakashatsi bwinshi hamwe ningero byerekana imikorere ya RDP mugutezimbere kurwanya sag:
a.Inyigo ya 1: Gushyira mu bikorwa RDP mu gufatira tile kumishinga minini yubucuruzi, byerekana imbaraga zo kurwanya sag hamwe nigihe kirekire.
b.Inyigo ya 2: Isuzuma rya RDP ryahinduwe mu mpande zerekana ko irwanya sag irwanya kandi irwanya ikirere.
C. Urugero rwa 1: Kugereranya sag irwanya minisiteri hamwe na RDP itongeyeho, byerekana iterambere ryagezweho hamwe na RDP.
d.Urugero rwa 2: Ikigeragezo cyikibanza cya RDP cyahinduwe cyo kuringaniza ibice, byerekana ubworoherane bwo gukoresha no guhangana neza na sag mugihe cyisi.
Isupu ya polymer isubirwamo (RDP) igira uruhare runini mukuzamura ubukana bwibikoresho byubwubatsi, bitanga guhuza imbaraga zo gukanika imashini, gukora firime no kubika amazi.Mugusobanukirwa uburyo nibintu bigira ingaruka kumurwanya no gukoresha uburyo bukwiye bwo gusuzuma, injeniyeri naba rwiyemezamirimo barashobora gukoresha neza RDP kugirango bagere kubisubizo birambye kandi byubaka.Binyuze mu bushakashatsi no guhanga udushya, biteganijwe ko RDP izakomeza kuba inyongera y’ingenzi mu gukemura ibibazo bijyanye no kugabanuka no guteza imbere urwego rw’ibikoresho byubaka.
