Imishini ye-asphalt e-Emulsified ikhokha ngokukhethekile inqubo yokusebenza enemininingwane
Kunezinhlobo ezimbili eziyinhloko zezindlela zokuguqula imishini ye-asphalt e-emulsified: indlela yokuxuba yangaphandle kanye nendlela yokuxuba yangaphakathi. Indlela yokuxuba yangaphandle iwukwenza kuqala umshini wetiyela owenziwe nge-emulsified, bese wengeza i-polymer latex modifier emshinini oyisisekelo we-asphalt we-emulsified, bese uxuba futhi ugovuze ukuze ukwenze. I-emulsion ye-polymer ngokuvamile ivela njenge-CR emulsion, i-emulsion ye-acrylic ehlobene ne-SBR emulsion, njll. Indlela yokuxuba yangaphakathi ukuqala ukuxuba irabha, ipulasitiki nezinye izithasiselo ku-asphalt enombala oshisayo. Ngemuva kokuxuba ngokulinganayo nokuthola ukusabela okuphelele phakathi kwe-polymer ne-asphalt enemibala, i-asphalt eguquliwe ye-polymer iyatholakala. Isinyathelo esilandelayo siwukuba i-modified asphalt emulsion idalwe ngobuciko be-emulsification, futhi i-polymer evame ukusetshenziswa endleleni yokuxuba yangaphakathi yi-SBS. Uma i-asphalt enombala imisiwe ihora ngemva kokuxuba, hlanza ingaphezulu lomgqomo wokuxuba, engeza amanzi ahlanzekile, futhi ukhuhle udaka luhlanzekile. Okulandelayo, khipha amanzi, uqiniseke ukuthi akukho ukuqoqwa kwamanzi ebhakedeni ukuvimbela izinguquko ku-iresiphi noma ngisho nokugqwala ohlelweni lokusebenza njengewebhusayithi. Phakathi nenqubo, wonke umuntu uyazi ukunaka ngokukhethekile izinqubo eziningi ezincane zokusebenza ukuze agweme ukulahlekelwa okungadingekile emisebenzini yabo.
Inqubo yokusebenza kwemishini ye-asphalt e-emulsified:
Ukulimala okungaphezulu kwengcindezi yempahla ye-asphalt e-emulsified kanye namanzi kuhluke kakhulu, futhi azihlanganisi kalula emazingeni okushisa ajwayelekile noma aphezulu. Lapho okokusebenza kwe-asphalt e-emulsified kwenziwa isenzo somshini esifana ne-centrifugation, ukusika, kanye nomthelela, okokusebenza kwe-asphalt emulsified kuphenduka izinhlayiya ezinosayizi wezinhlayiyana ezingu-0.1~5 μm, futhi zisatshalaliswa emanzini aqukethe i-surfactant (emulsifier-stabilizer) Phakathi nendawo. , i-emulsifier ingakhangiswa ngendlela eqondile ebusweni bezinhlayiya ze-asphalt ezinombala we-emulsified, ngaleyo ndlela kuncishiswe ukungezwani phakathi kwamanzi ne-asphalt enemibala, okuvumela izinhlayiya ze-asphalt ezinombala ukuba zenze uhlelo lokusabalalisa olujabulisayo emanzini. Imishini ye-asphalt e-emulsified kanye nemishini ingamafutha emanzini. ukwakheka kwe-emulsion. Lolu hlobo lwesistimu yokusabalalisa lunsundu, lunetiyela elinemibala njengesigaba esihlakazekile namanzi njengesigaba esiqhubekayo, futhi lijabulela uketshezi oluhle kakhulu ekamelweni lokushisa. Imishini nezinsiza ze-asphalt e-emulsified Ngomqondo othile, imishini ye-asphalt e-emulsified kanye nezinsiza zisebenzisa amanzi "ukugoba" i-asphalt enemibala, ngaleyo ndlela ilawula ukugeleza kwetiyela elinemibala.
Impahla ye-asphalt e-emulsified iyashisa incibilika itiyela elinemibala eyisisekelo futhi isabalalise ngokuzenzakalelayo izinhlayiya zetiyela ezinombala kusixazululo esinamanzi esiqukethe i-emulsifier ukuze kwakhe into ewuketshezi ye-asphalt enombala. Udaka lwempahla ye-asphalt eyenziwe ngosimende esetshenziswa ekwakhiweni kwe-slab ballastless track isebenzisa imishini yetiyela e-cationic emulsified. Inhloso ukulungisa ukunwebeka, ukuqina kanye nokuqina kosimende emulsified asphalt imishini udaka. Ama-polymers ngokuvamile asetshenziselwa ukuguqula i-asphalt.
