Redispersible Polymer Powder (RDP) igira uruhare runini mubikoresho byubwubatsi bugezweho, cyane cyane mukwiyubaka. Ibi bikoresho, byingenzi mugutegura neza ndetse na substrate, byunguka cyane mugushyiramo RDP.
Ibigize nibyiza bya RDP
RDP ikomoka kuri polymers nka vinyl acetate, Ethylene, na acrylics. Inzira ikubiyemo gutera-kumisha amazi ashingiye kumazi kugirango habeho ifu ishobora gusubira mumazi, bigakora emulisiyo ihamye. Ibintu byingenzi bya RDP birimo ubushobozi bwayo bwo kunoza imiterere, guhinduka, no kurwanya amazi mubikoresho byubwubatsi.
Ibigize imiti: Mubisanzwe, RDPs ishingiye kuri vinyl acetate-Ethylene (VAE) copolymers. Izi polymers zizwiho kuringaniza hagati yimiterere nimbaraga, bigatuma zikoreshwa mubikorwa bitandukanye byubwubatsi.
Ibyiza bifatika: RDP mubisanzwe igaragara nkifu nziza, ifu yera. Iyo ivanze namazi, ikora latex ishobora kuzamura imiterere yimvange ya sima. Ubu bushobozi bwo gusubira muburyo bwumwimerere bwa emulsiya ningirakamaro kumikorere yabwo murwego rwo kwishyira hamwe.
Uruhare rwa RDP murwego rwo Kwishyira hamwe
Kwishyira hamwe-kwivanga ni simaitike ivanze yagenewe gukora isura nziza kandi iringaniye nta murimo mwinshi. Kwinjiza RDP muriyi mvange bizana ibintu byinshi byongera:
Kunoza imigendekere myiza no gukora: RDP itezimbere rheologiya yuruvange, ituma imigendekere myiza nogukwirakwira. Uyu mutungo ningirakamaro kugirango ugere kurwego rwimbaraga nimbaraga nke. Ibice bya polymer bigabanya ubushyamirane bwimbere mubuvange, bituma butemba byoroshye hejuru ya substrate.
Kuzamura Adhesion: Imwe mu nshingano zibanze za RDP ni ukuzamura ihuriro ryikomatanya ryurwego rwimikorere itandukanye. Ibi nibyingenzi byingenzi mugukora ibishoboka byose kugirango uruganda rugire ubumwe bukomeye nubutaka buriho, bwaba beto, ibiti, cyangwa ibindi bikoresho. Ibice bya polymer byinjira hejuru yubutaka, bitezimbere guhuza imashini no guhuza imiti.
Guhinduka no guhangana na Crack Resistance: Ihinduka ryatanzwe na RDP rifasha mukwimuka kwimuka rya substrate no kwaguka kwinshi, bityo bikagabanya amahirwe yo guturika. Ihindagurika ningirakamaro cyane mubidukikije bitewe nihindagurika ryubushyuhe cyangwa kugenda gake, byemeza uburebure bwubuso buringaniye.
Kubika Amazi: RDP itezimbere uburyo bwo gufata amazi yikomatanya. Ibi nibyingenzi mukurinda gutakaza amazi byihuse bishobora gutera amazi meza ya sima, bikavamo ubuso bworoshye kandi bworoshye. Gufata neza amazi byemeza ko sima ikira neza, ikagera ku mbaraga nziza no kuramba.
Imbaraga za mashini: Kubaho kwa RDP byongera muri rusange imiterere yubukanishi bwo kwishyira hamwe. Ibi birimo imbaraga zinaniza kandi zogukomeretsa, zingirakamaro kuramba no kwizerwa byigorofa. Filime ya polymer yakozwe muri matrix ikora nkibikorwa bishimangira, ikwirakwiza imihangayiko kandi ikazamura ubusugire bwimiterere.
Uburyo bwibikorwa
Imikorere ya RDP murwego rwo kwishyira hamwe irashobora kumvikana hakoreshejwe uburyo bwibikorwa:
Imiterere ya firime: Iyo hydrated no gukama, uduce twa RDP duhuriza hamwe kugirango dukore firime ikomeza ya polymer muri matrike ya sima. Iyi firime ikora nkibintu byoroshye kandi bikomeye bifata matrix hamwe, bikazamura ubumwe muri rusange.
Gupakira Ibice: RDP itezimbere ubwinshi bwo gupakira ibice mubice byonyine. Ibi biganisha kuri microstructure yoroheje kandi yuzuye, kugabanya ubukana no kongera imbaraga.
Guhuza imiyoboro: Iminyururu ya polymer ya RDP ikorana nibicuruzwa bitanga amazi ya sima, bigateza imbere imiyoboro ihuza ibice bya sima hamwe nuduce twinshi. Uku guhuza kwongerewe imbaraga bigira uruhare mubikorwa byiza bya mashini no kuramba.
Porogaramu ninyungu
Kwinjiza RDP murwego rwo kwishyira hamwe usanga porogaramu muburyo butandukanye:
Imishinga yo Kuvugurura: RDP-yongerewe imbaraga yo kuringaniza ibice nibyiza byo kuvugurura amagorofa ashaje kandi ataringaniye. Zitanga igisubizo cyihuse kandi cyiza kugirango tugere ku buso bunoze kandi buringaniye bukwiranye nubutaka bwakurikiyeho.
Igorofa yinganda: Mugihe cyinganda aho amagorofa arimo imitwaro iremereye hamwe nurujya n'uruza, imbaraga zongerewe imbaraga hamwe nigihe kirekire zitangwa na RDP nibyiza cyane.
Igorofa yo guturamo: Kubisaba gutura, RDP itanga ubuso bworoshye, butarangiritse bushobora kwakira ubwoko butandukanye bwo gutwikira hasi, harimo amabati, amatapi, hasi.
Imyenda yo gushyushya imishwarara: RDP yahinduwe-yo-kuringaniza ibice ikoreshwa kenshi nkibikoresho byo gushyushya imishwarara. Ubushobozi bwabo bwo gukora neza kandi buringaniye butuma ubushyuhe bukwirakwizwa neza kandi bikagabanya ibyago byo kwangirika kubintu bishyushya.
Ibidukikije nubukungu
Kuramba: RDP irashobora gutanga umusanzu mubikorwa byubwubatsi birambye. Imikorere yongerewe imbaraga yo kwishyira hamwe bivuze ko ibikoresho bike bisabwa kugirango ugere ku bwiza bwifuzwa, kugabanya ibyo ukoresha muri rusange. Byongeye kandi, kunoza igihe kirekire cya RDP-yongerewe amagorofa arashobora kuganisha ku gihe kirekire, bikagabanya gukenera gusanwa kenshi no kubisimbuza.
Gukoresha Ikiguzi: Mugihe RDP ishobora kwiyongera kubiciro byambere byo kwishyira hamwe, inyungu z'igihe kirekire akenshi ziruta amafaranga yimbere. Imikorere inoze, igabanya amafaranga yumurimo kubera kuyikoresha byoroshye, kandi igihe kirekire cyo gukemura igorofa itanga inyungu zubukungu.
Redispersible Polymer Powder ninyongera yingirakamaro murwego rwo kwishyira hamwe, itanga inyungu nyinshi zongera imikorere nigihe kirekire cyibisubizo bya etage. Ubushobozi bwayo bwo kunoza imigendekere, gufatana, guhinduka, nimbaraga za mashini bituma iba ingenzi haba mubikorwa byo guturamo no mu nganda. Mugusobanukirwa ibigize, uburyo, ninyungu za RDP, abahanga mubwubatsi barashobora gushimira neza uruhare rwayo mukurema ibintu byiza kandi biramba-bingana. Mugihe inganda zubwubatsi zikomeje gutera imbere, akamaro k'ibikoresho bikora neza nka RDP biziyongera gusa, bitere udushya kandi birambye mubikorwa byubaka.
