Ifu ya Rubber yahinduye bitumen (bitumenrubber, ivugwa nka ar) nubundi bwoko bushya bwibikoresho byiza byujuje ubuziranenge. Nubwoko bushya bwimiterere yuburyo buhebuje bukozwe mu ifu ya rubber ikozwe mu mapine yo guta imyanda, yongeweho nk'aho ahindura tutumen base. Cyakozwe binyuze mu bikorwa by'ubushyuhe nk'ubushyuhe bwo hejuru, inyongera n'amasaruro bivanze mu bikoresho bidasanzwe bidasanzwe. Ibikoresho. Irashobora kwagura ubuzima bwumuhanda hejuru yumuhanda, gabanya urusaku, kugabanya kunyeganyega, kunoza ituze ryumuriro numuriro, no kunoza ihohoterwa rishingiye ku gishushanyo. Munsi y'ibikorwa bihujwe na bitumen biremereye, imyanda ipine ifu, ifu ya rubraxtbos, kandi igahinduka urukurikirane rwimpinduka zumubiri nimiti kugirango uhuze kandi wagure ifu ya rubber. Uruyobe rwiyongera, ingingo yoroshye yiyongera, kandi virusi, ubukana, na elastike ya reberi na bitumen bakitabwaho, yonoza imikorere yo gukora umuhanda wa rubber bitumen.
"Ifu ya Rubber yahinduye bitumen" yerekeza ku ifu ya rubber ikozwe mu mapine yo guta imyanda, yongeweho nk'aho ahindura tutumen base. Cyakozwe binyuze mu bikorwa by'ubushyuhe nk'ubushyuhe bwo hejuru, inyongera n'amasaruro bivanze mu bikoresho bidasanzwe bidasanzwe. ibikoresho byo gukomera.
Ihame ryo guhindura Ifu rya Rubber ryahinduwe bitumen ni ibintu byahinduwe bya bitumen byahinduwe hamwe na reaction yuzuye ifu ya reberi hamwe na matrix bitumen munsi yubushyuhe bukabije. Ifu ya Rubber yahinduwe bitumen yazamuye cyane imikorere ya bitumen, kandi iruta ituro rikoreshwa cyane na SBS
akarusho

Ifu ya Rubber irashobora kongerwa kuri bitumen mukubaka imihanda nibyamu. Iyi porogaramu ntabwo yabanje kubijyanye no hanze kugirango ikoreshe amapine, ahubwo yononoza imitungo ya bitumen kurwego rusa niyature zidasanzwe zirimo elastomemezi nshya. Ibyiza byo kongera ifu ya rubber kuri bitumen harimo kugabanya impengamiro yumuhanda wo gucamo (cyane cyane mubice bikonje), biteza imbere iramba ryumuhanda, kurwanya amazi hamwe no gutuza kwamazi. Rubber-yahinduwe bitumen-yahinduwe iramba, iramba impuzandengo yimyaka irindwi kurenza kuvarumen gakondo ivanze.?
Rubber yakoreshejwe kuri bitumer yahinduwe ni polymer yoroshye cyane. Ongeraho ifu ya rubber kuri bitumen shingiro irashobora kugeraho cyangwa ikarenga ingaruka nka styrene-Butadiene-Styrene guhagarika copolymen repiporitun. Ibiranga ifu ya rubber yahinduwe bitumen arimo:
1. Kwinjira bigabanuka, ingingo yoroshye yiyongera, kandi ubukuru bwiyongera, byerekana ko gushikama ubushyuhe bwo hejuru bwa bitumen, kandi birashobora kunoza ibintu biteye ubwoba no gutera ubwoba no gusunika mu mutwe mu gihe cyo gutwara imizi.
2. Kumva ubushyuhe bigabanuka. Iyo ubushyuhe buri buke, bitumen buvuka, bigatera guhangayika muri kaburimbo; Iyo ubushyuhe buri hejuru, kaburimbo ihinduka yoroshye kandi igahindura ingufu zimodoka ziyitwara. Nyuma yo guhindura ifu ya rubber, ubushyuhe bwa bitumen buratera imbere kandi bwo kurwanya ibiteruka biratera imbere. Ububiko bwa vino yifu ya rubber yahinduwe bitumen iruta iy'umusenza shingiro, byerekana ko bitumen yahinduwe ifite uruhare runini kugirango bahindurwe.
3. Imikorere yubushyuhe buke iratera imbere. Ifu ya rubber irashobora kuzamura ubushyuhe-buke bwa tutumen kandi yongera guhinduka kwa bitumen.
4. Yamazaki. Uko umubyimba wa rubber bitumen wahawe hejuru y'amabuye yiyongera, karument ya bitumen yangirika ku mazi irashobora kunozwa kandi ubuzima bwo mu nzira burashobora kongerwa.
5. Kugabanya umwanda.
6. Ongera ubunini hagati yamapine yimodoka hamwe numuhanda hejuru no kuzamura umutekano wo gutwara.
Kudashira
However, the use of rubber powder in this way increases the cost of bitumen, and the addition of rubber powder to bitumen makes the bitumen mixture more difficult to handle (easy to stick) and increases the operation time. Rimwe na rimwe, bitumen irimo ubwinshi bwa reberi buroroshye gufata umuriro mugihe cyo gushonga, bityo birasabwa ko ibikubiye muri reberi i Rubber byahinduwe bitumen bigomba kuba bitarenze 10%.
