Iron ya bitumen: Petroleum yajugunywe ku nkombe z'isi kuva kera cyane muri kamere kandi ihura n'umwuka n'ubushuhe. Ibikubiyemo byamavuta yoroheje birashira buhoro buhoro, kandi bitumen byatumen bikozwe mugukora no kubeshya bikunze kuvangwa nuburyo runaka bwamabuye y'agaciro. Bitumen Kamere birashobora kugabanywamo muri bitumen, ibituba byatumen, submarine bya bitumen, ibisigazwa byamavuta, nibindi byimyaka myinshi yo kubitsa, kandi nyuma yingaruka zimeze nkambuka, hamwe ningaruka zatumen ziterwa nubushyuhe, igitutu, okiside, Imyanya, bagiteri, nibindi

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.

Ubushake-bukomeye na bitumer-elastike yahinduwe ni imiti yambukiranya bitumer idasanzwe hamwe numuyoboro mwiza wahinduwe. Pofening Point yacyo igera kuri 85 ° C na vino yayo ifite imbaraga igera kuri 580.000 Pa · s. Numuco usanzwe uhindura bitumen. Inzozi zifite imbaraga ni inshuro 3 za bitumen kandi zifite imikorere yubushyuhe buhebuje. Muri icyo gihe, umuyoboro wacyo ugera kurenga 45cm, ubushyuhe buhebuje-buke bwamagana, gukira kwa elastike birenze 95%, ubushobozi buhebuje bwo kugarura 95% n'ubushobozi bukabije no kurwanya cyane.

Koresha SBS nkibikoresho byingenzi kuri ecran computibilizers ikwiye hamwe na formula. Koresha invange isanzwe kugirango wongere igipimo runaka cya reactée, ubushyuhe hanyuma uyivange na matrix zitandukanye kuri 160 ° C, hanyuma ukore micorbatch binyuze mubikorwa byiza.

1. Eva yahinduye bitumen Eva ifite neza na bitumen kandi irashobora gushonga kandi igatangwamo imishinga ishyushye yatunze Viscosity, delastique ndende hamwe nubufatanye bukomeye bwahinduwe bitumen. Isubukuru ya bitumen irakwiriye cyane kuri bitumen yahinduwe bitumen, ariko iyo ikoreshwa kuri bitumen nyinshi, kumena ibinyabiziga bikunze kugaragara, bigatuma ikizamini kidashoboka. Urebye ibi, birasabwa gukoresha imashini yipimisha ku isi hose kugira ngo ugere ku rubyiruko rwo gukomera kwa bitumen, andika imirongo-streve-stin, kandi ukoreshe uburyo bwo kwishyira hamwe kugirango ubare byoroshye ibisubizo by'ibizamini. 3. Ibirimo Byinshi bya rubber byahinduwe bitumen hamwe na karubone hamwe nintego za karubone hamwe nibitego byo kutabogama Inganda zipine zagize ikibazo cya "umusaruro mwinshi nimyanda minini kandi zivumburwa no gukora. Amapine arasaba gukoresha umutungo kamere n'imbaraga mu musaruro kugeza aho uhakanwa. / Amapine yo guta imyanda arashobora kugarura ibikoresho nimbaraga, gutunganya karubone mubicuruzwa, kandi ugere ku ntego yo kugabanya ingufu no kugabanuka kugabanuka no kugabanuka.  Amapine yo guta amapine nibikoresho bya polymer byoroshye bigoye kubitesha agaciro. Bafite uburyohe kandi bukaze kandi nta mpinduka zumubiri cyangwa imiti zibaho mubushyuhe bwa -50c kugeza 150c. Kubwibyo, niba bemerewe gutesha agaciro mu buryo busanzwe mu butaka, ntibazongere kwibasira urugero rwo gukura kw'ibihingwa, inzira ishobora gufata imyaka igera kuri 500. Umubare munini wamapine urundanyije uko bishakiye kandi ufata ubutaka bunini, birinda gukoresha neza umutungo wubutaka. Byongeye kandi, kwegeranya amazi maremare mu mapine bizarokora imibu no gukwirakwiza indwara, bigatera akaga katewe n'ubuzima bw'abantu.

Muri rusange, SBS Guhindura Bitumen bisaba inzira eshatu: kubyimba, guhindagurika (cyangwa gusya), hamwe niterambere./ hari isano ya hafi hagati yo kubyimba no kumarana. Ingano yo kubyimba bigira ingaruka ku buryo butaziguye. Niba SBS ibyimba bitagira akagero muri bitumen, sisitemu iba ifitanye isano rwose. Imyitwarire yo kubyimba ifitanye isano rya bugufi no gukora, gutunganya ikoranabuhanga no kubika ubushyuhe bwinshi bwa bitumen. Mugihe ubushyuhe bwiyongera, igipimo cyihuta cyihuta cyane, kandi kubyimba biragaragara kumubumba wo gutunganya ibinyabiziga bishonga hejuru yubushyuhe bwinzibacyuho ya PS ya SBS. Byongeye kandi, imiterere ya SBS ifite ingaruka zikomeye kumyitwarire yo kubyimba: umuvuduko mwinshi wa sbs-sbs zitinda kurenza iyo mirongo ya sbs. Kubara bifatika byerekana ko ubucucike bwibice bya SBS bwibanda kuri 0.97 na 1.01G / CM3, ari hafi yubucucike bwa fenol nziza.
