SMA - Kibuye Mastike Asfalt-ntabwo arikindi kintu cyihariye cya asfalt. Ni igipimo ngenderwaho. Iyo umuhanda munini utwara ibinyabiziga 30.000+ burimunsi, mugihe umuhanda wikibuga cyindege uhura nindege hamwe nigare ryubushyuhe bwumuriro, kandi iyo imihanda yo mumijyi yihanganira guhagarara no kugenda feri nubushyuhe bwimpeshyi hejuru ya 65 ° C, ivangwa ryurwego rwinshi rwinshi ruvunika, rutobora, cyangwa okiside igihe kitaragera. SMA itanga ibyo ibyo bivanga bidashobora: gufatanya skeleton yamabuye, polymer-yahinduwe bitumen binder, hamwe na selile cyangwa minerval yuzuza kugirango ifunge byose mumwanya. Ariko nta na kimwe muri ibyo gifite akamaro niba ari icyawe igihingwa cya asfalt SMA ubushobozi bugufi.

Twabibonye kurubuga: igishushanyo mbonera cya SMA cyemejwe na laboratoire, nyamara cyangwa kuri paveri kubera guhuza ibintu bidahuye cyangwa gutandukanya hamwe. Intandaro ntabwo yari resept-yari igihingwa. SMA isaba kugenzura ubushyuhe bukabije (± 2 ° C), kuzuza neza kuzuza (± 0.3% kubwinshi), guhuza ubukonje bwa zeru mu kuvanga, hamwe no guhuza ibitsina byuzuye mu masegonda 45 - ntabwo ari 90. Ibimera bisanzwe byingoma birarwana. Ibihingwa bya Counterflow bikunze gushyushya binder. Kandi ubwoko bwubwoko bwa sisitemu idafite inzira ebyiri-zuzuza inzira zuzuza na bitumen ntishobora gukubita inshuro.

Zibo Jixiang Machinery ya asfalt yo guteramo ibiti ihura na SMA imbonankubone-ntabwo ari igitekerezo, ahubwo ni manda yo gushushanya. Urukurikirane rwabo rwa SjABP rugaragaza amahitamo atatu adashobora kuganirwaho muburyo bwa tekinoroji: Icya mbere, ibyatanzwe byuzuye-byuzuye byuzuye byuzuye byuzuye byuzuye amarembo agenzurwa na servo hamwe nibitekerezo bya gravimetric-nyabyo-nta munzani wumukandara, nta drift. Icya kabiri, sisitemu yo gutanga bitumen ya bitumen: umurongo umwe wa binder base, imwe ya polymer yahinduwe ibiryo bishyushye, buri kimwe hamwe no kugenzura ubushyuhe bwigenga hamwe na kalibrasi. Icya gatatu, ivanga rya shaft ebyiri-ivanga umuvuduko uhinduranya umuvuduko hamwe nu byuma bigabanijwe - byashizweho kugirango bitwikire ibice byose bitarinze guteranya ingoyi cyangwa gutesha agaciro iminyururu ya polymer.

Kohereza kwisi-byukuri birabyemeza. Mu kuzamura umuhanda wa 2023 mu Ntara ya Quang Nam yo muri Vietnam, umukiriya yavuye mu ruganda rusange rw’ingoma rw’i Burayi yerekeza mu gice cya SjABP-160 cya Zibo Jixiang. Umusaruro wa SMA wavuye kuri 72% kuri buri cyiciro (kuri EN 13108-5) ugera kuri 98,6%. Kubera iki? Ntabwo ari ibyuma gusa - kugenzura ibintu bifite akamaro. Imigaragarire yabo ya PLC ifunga ibipimo byingenzi: inyongera yuzuza igomba kubaho * nyuma yubushyuhe bwumye ariko * mbere yo guterwa bitumen; kuvanga umwanya usubiramo gusa mugihe sensor zose zemeza intego temp hamwe numutwaro wa torque. Nta mukoresha urenga byemewe. Nuburyo ukuraho amakosa yumuntu ahinduka muri SMA.

Bamwe bashobora kuvuga ko ibimera bigizwe nigitambo cyo kwihuta. Bafite ukuri-niba ikadiri idakozwe muburyo bwo gutwara ibintu. Zibo Jixiang ikoresha ibyuma-byacishijwe bugufi, byorohewe nicyuma cyubatswe kuminara yabo nkuru. Buri rugingo ni CNC yacukuwe kandi ihindagurika - ntabwo isudira mu murima - kugirango ibungabunge kwihanganira guhuza kwaguka. Twapimye guhagarikwa guhagaritse kuri SjABP-120 mugihe gikomeza amasaha 12 SMA ikora: 0.8 mm kuri temp temp (175 ° C), munsi ya 2.5 mm ISO 50001 kugirango tuvange uburinganire. Ukwo gushikama guhindurwa muburyo butaziguye-muri-minerval-igiteranyo (VMA) indangagaciro-ingenzi kuburambe bwa SMA.

Igiciro ntabwo kijyanye nigiciro gusa. Toni ya SMA idahwitse igura ibirenze gukora - itera ubukererwe, ibyangiritse, hamwe ningaruka zizwi. Ibihingwa bya Zibo Jixiang byacishije imyanda kubishushanyo mbonera: sisitemu yo gufunga umukungugu wo gufunga ifu yongeye gufata> 92% byamafaranga yuzuza, ikabagaburira muri dopper. Igenzura ryabo rihindura igipimo cya lisansi yumwuka mugihe nyacyo gishingiye kuri gasi ya Oue isoma-kugabanya ikoreshwa rya lisansi 11% na sisitemu igereranijwe idatanze ubushyuhe. Kandi kubera ko sisitemu zose zikomeye - gupima, gutanga, kuvanga-zubatswe munzu, ibice byabigenewe bigera muminsi 12, ntabwo ibyumweru 12. Umukiriya umwe muri Qazaqisitani yatangaje ko 94% yigihe cyamezi 18 mugihe cya SMA, hamwe na zeru zateganijwe ziteganijwe kurenza iminota 47.

Guhitamo an igihingwa cya asfalt SMA igisubizo bivuze guhitamo aho ubwumvikane burangirira. Ntabwo ucuruza ubudahwema kumuvuduko. Ntabwo wemera "gufunga bihagije" kuri VFA cyangwa draindown. Wubaka ibikorwa remezo bimara-bidahuye gusa na spec, ariko birenze ibyateganijwe munsi yumutwaro nyawo. Imashini Zibo Jixiang ntabwo igurisha ibihingwa bya asfalt. Batanga ibyasubiwemo SMA-byahinduwe, bigenzurwa, kandi byiteguye kumyaka 20 iri imbere yimodoka.
