Iyo ibihingwa bya asfalt bifashishije tekinoroji ya SMA (Stone Mastic Asphalt), kugaburira fibre lignocellulose ntabwo ari ugutekereza-ni inzira ikomeye. Twabonye imishinga myinshi ihagaze kubera ko uwagaburira adashobora gukomeza guhora 3-5 g / kg ikabije kumugezi wa 200+ ° C bitumen. Niyo mpamvu abashoramari bagenda bagaragaza ibiryo bya lignocellulose SMA kubihingwa bya asfalt ibice byubatswe mubyukuri-isi yubushyuhe, kurwanya ivumbi, no gupima gusubiramo-ntabwo ari laboratoire.

Ntibikiriho "Byiza Birahagije" Kugaburira Fibre

Fibre ya Lignocellulose - ubusanzwe ishingiye ku biti, mm 3-6 z'uburebure, hamwe n'ubushuhe buri munsi ya 8% - birashoboka ko winjira muvanga ku kigero kinini cy’imigezi. Gito cyane: gukenera binder ya firime, ibyago byo gutembera. Byinshi: guhuzagurika, kubura umwuka, umunaniro utaragera. Abagaburira benshi bananiwe ku ngingo eshatu: ikiraro cya kiraro mu kirere cyinshi, kunyerera kwa auger munsi yumutwaro, cyangwa kugabanuka kwatewe no guhindagurika mugihe cyo gutangira ibihingwa. Imashini ya Zibo Jixiang SMA yihariye ya lignocellulose igaburira ikemura mubishushanyo-ntabwo ari retrofit.

Urukurikirane rwabo rwa SjLF-120 rukoresha sisitemu yo kugaburira ibyiciro bibiri: imbaraga zifasha imbaraga za vibratory hopper hamwe no kugenzura amplitude igenzurwa, ikurikirwa na convoyeur ifunze, idafite ibyuma-ibyuma byerekana ibitekerezo. Bitandukanye nibiryo rusange byigaburo, bikomeza ± 1,2% byukuri mubuso bwa 0.8-12 kg / h - byagenzuwe mubigeragezo byakozwe mubushuhe bwubutayu bwa Arabiya Sawudite hamwe nubushuhe bwimvura ya Vietnam. Igipimo cyo kugaburira gihinduka mugihe nyacyo ukoresheje PLC ihuza ibimenyetso bya bitumen bitemba, bikuraho intoki.

Icy'ingenzi, ihuza neza na sisitemu isanzwe yo kugenzura asifalt-nta byuma byinjira bikenewe. Twashizeho ibice hamwe na Benninghoven, Ammann, hamwe no kuvanga ingoma. Buri cyinjizwamo cyarimo kurubuga rwa kalibrasi ukoresheje fibre yemewe ya fibre, ntabwo igicapo cyo kwimura amajwi gusa.

Impamvu Abagaburira Basanzwe Bagwa Mugufi muri Porogaramu ya SMA

Abashoramari bamwe bagerageza guhuza sima cyangwa kuguruka ibiryo by ivu kuri lignocellulose. Ni gake ikora. Abagaburira sima bashingira kumazi; lignocellulose yirukana umwuka. Kugaburira ivu biguruka ifu nziza; lignocellulose ni fibrous kandi ihagaze neza. Umukiriya umwe muri Kenya yayoboye ibyiciro bitatu bikurikiranye hamwe na Marshall adahwitse-gusa basanze ibiryo byabo "rusange" byegeranije g 47 za fibre zisigara inyuma y irembo risohoka nyuma yamasaha 8. Ibyo ntabwo ari ukubungabunga-ni kunanirwa gushushanya.

Ibiryo bya Zibo Jixiang bifashisha ibyuma bidafite inkoni ya polymer, kwisukura auger geometrie, hamwe na cycle yo gukuraho yatangaga buri minota 90-cyangwa kubisabwa. Ibisohoka bisohoka mu muyoboro wa bitumen, bigabanya igihombo cyo mu kirere. Nta mufasha wo mu kirere wo hanze. Nta byuma bya kabiri. Kugenzurwa gusa, kugaburira imbaraga-kugaburira aho fibre ihura na binder.

Ibisabwa byoherezwa nyabyo-Ntabwo ari udutabo dusaba

Kwiyubaka ntabwo ari plug-no-gukina-ariko birateganijwe. Ukeneye 300 mm yohanagura munsi yisoko rya hopper, ikadiri yo gushiraho (idasudira kugirango ibimera bihinda umushyitsi), hamwe na mA 4-20 mA kuva muri PLC nkuru yawe. Nta mwuka ucanye usabwa. Nta bikorwa bya gisivili birenze ibyuma bibiri bya M12. Gukoresha bifata munsi yiminota 90: kalibrasi ya zeru, gukora ibizamini byuzuye, no kugenzura amakuru yatanzwe.

Twohereje ibice birenga 87 kuva 2021-muri Nijeriya, Uzubekisitani, Kolombiya, na Polonye. Mubibazo byose, toni 200 yambere ya SMA yakozwe yahuye na EN 13108-5 ya fibre ikwirakwiza fibre idafite uyikora. Ibarura ry'ibicuruzwa? Igikoresho kimwe gikubiyemo 95% yo gusana umurima: kashe ya auger, guhuza ibinyabiziga, hopper liner set. Igihe cyambere cyo gusimbuza ibice: iminsi 12-18 inzu ku nzu, ikurikiranwa.

Ariko dore icy'ingenzi cyane: iyo kunywa fibre bigumye mu kwihanganirana, ubusa bwa SMA yawe-muri-minerval-agregate (VMA) ihagaze neza kuri 17.2 ± 0.3%. Ibyo guhuzagurika bisobanura ingero nke zintangarugero zanze, gukora bike, no kwakirwa byihuse. Ngiyo ROI upima muminsi-ntabwo ari icya kane.

Guhitamo Iburyo bwiza bwa Lignocellulose SMA kubihingwa bya Asfalt

Baza ibibazo bitatu mbere yo kwerekana:

Zibo Jixiang atangaza ibyangombwa bya tekiniki byuzuye kumurongo - harimo ibishushanyo mbonera, ibishushanyo mbonera, hamwe na lisiti yatanzwe. Nta NDA isabwa. Nta marembo yo kugurisha. Gusa ubwubatsi-urwego rwo gukorera mu mucyo.

Ku bimera bya asfalt ikoresha SMA kuri toni 200+ / isaha, kwizerwa ntabwo bijyanye nigihe cyo hejuru. Nukumenya fibre ya fibre ntizahinduka mugihe ubuhehere bwibidukikije bugera kuri 92% cyangwa pompe ya bitumen cycle saa tatu za mugitondo Ibyo byukuri bitangirana na ibiryo bya lignocellulose SMA kubihingwa bya asfalt—Kurangirana na kaburimbo imara.
