1. Uyini umklamo wamathangi e-asphalt kanye nobuchwepheshe bayo bokucubungula?
Amathangi e-asphalt asetshenziswa kakhulu emkhakheni wemigwaqo yokwakha, okuletha ukukhululeka okukhulu kubasebenzi, kodwa uyazi ukuthi amathangi e-asphalt enziwa kanjani? Ake siyibheke ndawonye.
1). Lapho wenza futhi uklama, kuyadingeka ukunaka ukunciphisa inkinga ye-asphalt esele kakhulu phansi kanye nokungakwazi ukuyisusa ngokuphelele, futhi uzame ukwenza insalela ye-asphalt ekusetshenzisweni okuvamile ngaphansi kwesentimitha elilodwa, elinganciphisa futhi. izinga lokusebenzisa.
2). Ukwakhiwa kwethangi le-asphalt kufanele kuhlangabezane nezidingo zangempela, futhi kuqinisekiswe ukuthi imishini ye-asphalt ekhishwe kancane ingahlanganiswa eduze nobuchwepheshe bokushisa beqembu, ukuze kukhiqizwe inani elikhulu lemikhiqizo eqediwe, futhi ngesikhathi esifanayo. isikhathi, izidingo zokukhiqizwa kwenqwaba encane nezinkulu zingahlangatshezwana nazo. Ngokufanayo, ukugcwaliswa kokushisa kwe-asphalt nakho kwenziwa ngendlela efanayo.
3). Uma ithangi le-asphalt lingakwazi ukuxazulula inkinga yokususwa okunzima kwe-asphalt, khona-ke ithangi le-asphalt lingakwazi ukukhiqiza ngokuqondile imikhiqizo yokushisa ephezulu, elula kakhulu. Abakhiqizi bethangi le-asphalt bathi kuyadingeka ukuqinisekisa ukuthi isikhathi sokusebenza esiqhubekayo sethangi le-asphalt asidluli ihora elilodwa, ngakho-ke kuyadingeka ukusetha uhlelo lokujikeleza kwamafutha okushisa okushisa okuphezulu, ukukhiqizwa kwamandla kagesi aphansi kanye nokushisa okuphezulu, futhi ingozi encane.

2. Unganciphisa kanjani ukuvela kwezinkinga ezivamile emathangeni e-asphalt
Ngemuva kokufakwa kwethangi le-asphalt, kuyadingeka ukubheka ukuthi ukuxhumeka kwezingxenye ezahlukahlukene zokucushwa kuqinile futhi kuthambile, ukuthi izingxenye ezisebenzayo ziyalawuleka, ukuthi ipayipi libushelelezi, noma ngabe izintambo zokuphakelwa kwamandla ziyithangi le-asphalt, futhi faka i-asphalt e-emulsified kanye. Sicela uvule i-valve yokukhipha umoya othomathikhi ukuze uvumele itiyela elifakwe emulsified ukuthi lingene ngempumelelo kudivayisi yokushisisa kagesi.
Ithangi le-asphalt eliphathwayo elisheshayo elisheshayo elishisayo ethangini le-asphalt aligcini nje ngokuba nesivinini sokushisa esisheshayo, lisindisa uphethiloli, futhi alingcolisi umoya, inqubo yokusebenza ilula futhi kulula, futhi uhlelo lokushisa oluzenzakalelayo luqeda ngokuphelele inkathazo yokubhaka. noma ukuhlanza itiyela namapayipi. Ngesikhathi sokusebenza, sicela ubheke ngokucophelela umugqa wezinga lamanzi futhi ulungise i-valve yokumisa ukuze ugcine umugqa wezinga lamanzi uxhumeke endaweni efanele kusukela ekuqaleni kuya ekugcineni.
Emishini emikhulu yamathangi e-asphalt njengamathangi e-asphalt, kubaluleke kakhulu ukwenza umsebenzi omuhle wokuhlolwa kwansuku zonke, okuzuzisa ukunciphisa amathuba okuhluleka kwemishini yamathangi e-asphalt, futhi kuyazuzisa ukugcina imingcele yokusebenza. yomkhiqizo futhi andise impilo yesevisi yomkhiqizo.
Ngokusho kwezimpawu zokusetshenziswa komgwaqo, uchungechunge lomkhiqizo lwamathangi e-asphalt wemishini yengxube ye-asphalt luhlukaniswe izigaba ezintathu: i-matrix yezimbali, amapulasitiki obunjiniyela ashintshiwe, kanye nekhethekile, ahlanganiswe nezidingo ezahlukahlukene zemakethe egandayiwe enemibala. Isibonelo, kufanele sidinge ukusampula nokuhlolwa kwamathangi e-asphalt kanye njalo ezinyangeni eziyisithupha. Uma kutholakala ukuthi i-antioxidant yehlile noma uwoyela ophelile ungcolile, i-anti-oxidant kufanele yengezwe ngokushesha, upharafini kufanele wengezwe ethangini lokuqopha lokunwebeka, noma ithangi le-asphalt lokudlulisa ukushisa lokushisa okuphezulu kufanele lifakwe kahle. kuhlungiwe.
Ngaphezu kwalokho, ekusetshenzisweni kwamathangi e-asphalt, uma kwenzeka ukuphela kukagesi kungazelelwe noma izinkinga zesistimu yokujikeleza, ngaphezu kokupholisa ukujikeleza komoya, kuyadingeka futhi ukusebenzisa uwoyela wokudlulisa ukushisa obandayo wokushisa okuphezulu ukuze ushintshwe, okungukuthi, izisebenzi plus amafutha abandayo. Ukushintshwa kufanele kwenziwe ngokushesha nangokuhlelekile. Qaphela ukuthi ungavuli kakhulu iphampu kawoyela eshintsha uwoyela obandayo. Phakathi nenqubo yokushintshwa, idigri yokuvula ipompo ye-asphalt esikhundleni sikawoyela isuka kwenkulu iye kwencane, futhi isikhathi sokushintsha sifinyezwa ngangokunokwenzeka. Ithangi le-asphalt lomshini we-Emulsified Leli thangi le-asphalt lisebenzisa ukushisa kwe-L-band njengendawo yokudlulisa ukushisa, amalahle ahlanzekile, igesi yemvelo noma isithando somlilo sikawoyela njengomthombo wokushisa, futhi iphoqeleka ukuthi ijikeleze ngephampu kawoyela yokudlulisa ukushisa ukushisa itiyela endaweni yokusebenza. izinga lokushisa. Isici esikhulu saleli tanki le-asphalt ukushisa okusheshayo, okungakwazi ukucubungula inani elikhulu le-asphalt yokushisa okuphezulu, kodwa futhi konga amandla nokuthola inani elincane le-asphalt eshisayo okwesikhashana. Ukucutshungulwa kwetiyela elishisayo ku-160 ℃ ngokuvamile akudluli amahora angu-4. Ukwengeza, uwoyela obandayo okwanele kufanele uqinisekiswe ukuthi uzoshintshwa ukuze kuvinjwe imishini yokwelapha ukushisa ethangini likawoyela we-asphalt okudlulisa ukushisa okwanele ekubeni sendaweni engenawo uwoyela noma isimo sokuntuleka kukawoyela.
