Ingaruka z'ubushyuhe bwinshiInzira yo gucukuraImikorere

Gukoresha imashini ziremereye mu gihe cy'impeshyi nyinshi bitera ubushyuhe bwinshi ku bice biri munsi y'imodoka. Abayobozi b'amato n'abahanga bakorera mu turere tw'ubushyuhe bwinshi bahora babona ko ubushyuhe bwinshi bwo mu kirere—akenshi burenze 95°F (35°C)—bushobora guhindurwa ubushyuhe bukabije bwo hejuru ya asphalt cyangwa sima, rimwe na rimwe bukarenga 140°F (60°C). Muri ibi bihe bikomeye, imiterere isanzwe ya rubber iragabanuka vuba, akenshi ikagabanya igihe cyo kubaho muri rusange kuva kuri 20% kugeza kuri 30%. Gusobanukirwa imiterere y'ubushyuhe ni ngombwa kugira ngo hamenyekane ibikoresho bikwiye, hashyirweho amabwiriza akwiye yo gukaza umuvuduko, kandi hakumirwe igihe gihenze cyo guhagarika mu gihe cy'umushinga ukomeye.

Uburyo bwo kureba ikibazo giterwa n'ubushyuhe

Kunanirwa gukomoka ku bushyuhe ntibikunze kubaho mu ijoro rimwe; bigaragarira mu kwangirika kw'ibikoresho buhoro buhoro. Ikibazo gikunze kubaho ni ukugwa, aho irangi ritakaza ubushobozi bwaryo bwo gukomera, rigakomera iyo rihuye n'imirasire y'izuba, kandi rikava mu cyuma gishyushye cyane. Gukomeza gukoresha asphalt ishyushye cyane bishobora kugabanya cyane igihe irangi risanzwe rimara amasaha 1.500-2.000 kugeza ku masaha 800-1.200. Nubwo kugabanuka nyako gutandukanye cyane bitewe n'uruganda, akarere, n'ubwoko bw'imashini, kwangirika kwihuta kwabyo ni bibi ku isi yose.

Byongeye kandi, kwaguka k'ubushyuhe bigira ingaruka ku miterere y'imbere. Uko rubber yoroha kandi ibice by'imbere by'icyuma bigashyuha (akenshi birenga ubushyuhe bw'imbere bwa 180°F/82°C), ibyago byo gutandukana kw'insinga z'icyuma byiyongera kugeza kuri 40%. Iyo abakoresha bazunguruka cyane ku buso bushyushye cyane, rubber yoroshye ntishobora gufata insinga z'icyuma zigenda zikura, akenshi bigatera gucika kw'insinga.

Inzira za Rubber vs Inzira z'Icyuma vs Inzira zo Kuramo Bolt

Iyo usobanurainzira z'imishinga yo mu mpeshyi, gusuzuma uburyo ibintu bihinduka hagati y’ubwoko bw’ibikoresho ni ingenzi cyane. Inzira z’icyuma zidafite ibara ry’umukara zishobora kwihanganira ubushyuhe bukabije bw’ubuso (kugeza kuri 300°F/150°C) nta kwangirika kw’imiterere, ariko zangiza ubuso bwa kaburimbo, zigashyiraho amategeko akomeye yo gutwara no kubahiriza amategeko agenga imihanda, kandi zikongera umunaniro w’umukoresha binyuze mu gutigita no gukurura cyane (akenshi byongera 10–15 dB ku rusaku rw’inzu). Byongeye kandi, nubwo imiterere y’inyubako idakingirwa n’ubushyuhe bw’ubuso, inzira z’icyuma zitwara ingufu z’ubushyuhe mu buryo butaziguye ku byuma bizingurura, ibikoresho biziritse, n’ibifunga. Mu gihe cy’ubushyuhe bwinshi, iyi nzira ishobora kuzamura ubushyuhe bw’amavuta n’amavuta munsi y’ubutaka kuva kuri 15°F kugeza kuri 25°F, bigatuma ibifunga byihuta.

Igisanzweinzira zo gucukura za kabuturabitanga uburyo bwiza bwo gufata no kurinda ubuso, nyamara bibaho nabi cyane iyo ubushyuhe bw'ubutaka bugeze ku rwego rwo hejuru cyane rw'impeshyi.

Ku hantu hakoreshwa ibintu bitandukanye, imigozi ya rubber ishyirwa hejuru y'iminyururu y'icyuma ikunze kuba isabwa. Ubu buryo bwo guhuza butuma imigozi y'icyuma ikora cyane ishobora kwikorera umutwaro w'imiterere n'ubushyuhe mu gihe imigozi ya rubber ishobora gusimburwa ikora ku buso, bigatuma isanwa ry'aho iherereye aho gusimburwa. Ariko, amatsinda ashinzwe gutanga amasoko agomba kwita ku ngaruka zishobora gutesha agaciro ibikoresho by'ikoranabuhanga no guhuza ubwoko bw'imigozi; ubwikorezi bw'ubushyuhe n'imyanda ishobora gutera imigozi gusubira inyuma, bigatuma imigozi itandukana mu buryo busanzwe niba abakora badasuzuma buri gihe torque.

Ibisobanuro by'ingenzi ku mirimo ijyanye n'ikirere gishyushye

Kugena ibice bikwiye byo munsi y'imodoka mu gihe cy'ubushyuhe bisaba kureba kure y'uko bingana. Injeniyeri z'indege zigomba gusesengura neza imiterere y'ibikoresho no kubihuza n'ibyo imashini isaba mu mikorere yayo. Urupapuro rugaragaza imiterere rusa neza mu gihe cy'impeshyi rukunze kwangirika bitewe n'ubushyuhe budashira bw'umushinga wo kubaka inganda muri Nyakanga.

Uburyo bwo gukora imvange n'imbaraga z'inkambi

Ishingiro ry'ubushyuhe bwinshi riri mu buryo bwo gukora imvange. Guhitamo imvange bigomba kuringaniza neza gusaza k'ubushyuhe, kudashwanyagurika, no kudashwanyagurika. Aho kwishingikiriza gusa ku imvange isanzwe karemano, abaguzi bagomba gushaka imvange yihariye irimo elastomer za sintetike nka Styrene-Butadiene Rubber (SBR), chloroprene, cyangwa EPDM, bifasha kugumana ubuziranenge bw'imiterere ku bushyuhe bugera kuri 175°F (80°C) kandi biganisha ku mbaraga zo gukurura za 2,500–3,000 PSI. Ariko, guhitamo imvange bigomba guhuza n'uburyo bukoreshwa cyane; imvange zidashobora gushwanyagurika rimwe na rimwe zishobora gusimburana no kudashwanyagurika cyangwa kudashwanyagurika mu gihe cy'ubukonje ugereranije na imvange karemano.

Byongeye kandi, imigozi y'icyuma ikomeza kandi idafata ingingo (ifite umurambararo usanzwe uri hagati ya mm 4.5 na mm 5.5) ni ingenzi cyane mu bijyanye n'ubwiza bw'ibanze mu bihe bya none.inzira nziza za rubber, ntabwo ari ivugurura rigezweho. Amatsinda ashinzwe gutanga amasoko agomba kugenzura iyi miterere y’imizigo kandi akamagana byimazeyo ibikoresho by’imizigo bidafatanye neza cyangwa bifatanye neza bizananirwa vuba bitewe n’imbaraga zo kunanura ziterwa n’ubushyuhe. Bitandukanye n’imizigo y’imizigo ikomeza, ibyuma by’ibanze (ibice by’icyuma bihuza n’umuyoboro w’imodoka) bigomba kuba byarakozwe mu buryo bworoshye cyangwa bigakoreshwa mu buryo bworoshye kandi bushyushye. Ibi birinda kuvunika kw’imizigo iyo inzira ihinduka vuba cyane, bigatuma habaho guhuza neza n’ibice biri munsi y’umuhanda.

Uburemere bw'imashini, imikorere yayo, n'imiterere y'ubuso bwayo

Uburemere bw'imashini n'imikorere yayo bigena ingano y'ubushyuhe bw'imbere butangwa binyuze mu gukururana no guhindagurika. Ibi bintu bihinduka mu buryo butandukanye mu byiciro by'uburemere. Urugero, imashini ntoya zo gucukura (toni 1.5 kugeza kuri 3) zikora ingendo zihoraho zitanga ubushyuhe bukomeye bwo gushyushya imbere binyuze mu guhindagurika kw'inzira, mu gihe imashini nini zo gucukura (toni 5 kugeza kuri 8) zikoresha imbaraga nyinshi zo gukata inzira mu gihe cyo guhindukira. Uburyo bwombi bwihutisha kwangirika k'ubushyuhe. Kugira ngo ibi birwanye, abazikoresha bagomba kwemera igihe gihagije cyo gukonjesha (urugero, iminota 15 buri masaha 2 kugeza kuri 3 yo guhagarara buhoro buhoro) no kugabanya ingendo zidasanzwe ku muvuduko mwinshi, kuko ingano y'ubushyuhe itandukana bitewe n'ingano y'imashini, ubushyuhe bw'ikirere, n'ubwoko bw'ubuso.

Igitutu cy’ubutaka (ubusanzwe kuva kuri 4.0 kugeza kuri 6.5 PSI) nacyo kigira uruhare runini. Imashini zifite igitutu kinini cy’ubutaka zizashyira imbaraga mu butaka bushyushye cyane. Imashini yoroshya ubushyuhe ishobora kwinjira cyane; amabuye atyaye n’imyanda byinjira byoroshye cyane mu gihe cy’ubushyuhe, bityo bigasaba ko imashini ikomera kandi iramba kugira ngo hirindwe ko ipfumuka igera ku nsinga z’icyuma.

Gusana imirima mu bushyuhe bwinshi

Kugira ngo bazibe icyuho kiri hagati y’ibipimo by’ibikoresho bifatika n’imikorere yabyo, abayobozi b’aho hantu bagomba kugenzura ko abakora bashyira mu bikorwa amabwiriza akomeye yo kubungabunga imirima mu gihe cy’ubushyuhe.

Uburyo bwo Gushaka no KwemezaInzira z'umukara zo gucukura

Mu gihe cyo gushyiraho inzira zo gucukura mu bihe bikomeye by'impeshyi, gushaka ibikoresho bisaba ibirenze gusa guhuza ingano y'imodoka iri munsi y'ubutaka. Buri gihe nsuzuma abakora ibikoresho nkurikije ubushobozi bwabo bwa tekiniki bwo gutanga imvange za polymer zirinda ubushyuhe.

Igenzura ry'abatanga serivisi n'inyandiko zisabwa

Kugira ngo nkomeze ubushyuhe, nkeneye inyandiko zihamye za tekiniki mbere yo kwemeza umucuruzi mushya. Nubwo icyemezo cya ISO 9001 ari cyo shingiro ry’imicungire y’ubuziranenge bw’uruganda, nshyira imbere raporo z’ibizamini by’ibikoresho bya granular (MTRs). Ku bijyanye n’ubushyuhe bwinshi, nsaba abatanga serivisi ibisubizo bya laboratwari by’abandi bigaragaza imbaraga za rubber zo kugumana ubushyuhe nyuma yo gusaza, akenshi bigapimwa hakurikijwe ibipimo bya ASTM D573.

Mu kugenzura umutanga serivisi, nemeza inyandiko zikurikira:

• Raporo z'ibizamini by'ibikoresho:Kwemeza igipimo cyiza cy'urubura rusanzwe ugereranije na polimeri zikozwe mu buryo bwa sintetike (nk'urubura rwa styrene-butadiene, rwongera ubushobozi bwo kwirinda ubushyuhe).
• Amasezerano y'ingwate:Gushyira ahagaragara uburyo bwo gutwikira neza ubushyuhe, gutandukanya ubushyuhe n'ibice by'imikingo.
