Yikuphi ukuhlolwa okudingeka kwenziwe lapho kusetshenziswa imishini yebitumen eguquliwe?
Imishini eminingi izoba nezinkinga ezincane uma isetshenziswa. Ukuze usebenze ngokujwayelekile, umsebenzi wokuhlola wansuku zonke awunakugwenywa. Ake sibheke ukuthi yini i-bitumen eguquliwe (ukwakheka: i-asphaltene ne-resin) imishini okudingeka yenziwe ekuphileni kwansuku zonke. Iyini imisebenzi yokuhlola?
Kudingeka sihlole njalo i-emulsifier elungisiwe yesitshalo sebitumen esilungisiwe. Uma i-emulsifier isetshenziswe isikhathi eside futhi igebe phakathi kwesigayo se-bitumen colloid emulsified sizoba sikhulu, ngakho-ke sidinga ukusilungisa ngalesi sikhathi ukuze siqhubeke nokukhiqiza. Lesi isiqhathaniso Umbuzo olula: Isitshalo sebitumen esilungisiwe siwukwengeza izixube zangaphandle (izilungisi) njengerabha, inhlaka, ama-polymers amangqamuzana aphezulu, impushana yerabha egayiwe kahle noma ezinye izigcwalisi, noma ukuthatha izinyathelo ezinjengokucubungula i-oxidation encane yebitumen ukwenza itiyela Noma i-bitumen binder eyenziwe ngokwenza ngcono ukusebenza kwengxube yebitumen.
Hlaziya inkinga yezilungisi. Ngokuvamile, inani lama-modifiers angeziwe kufanele libe khona. Lapho wengeza, inani le-pH kufanele lilungiswe ngokuya ngekhwalithi yamanzi asetshenzisiwe. Lolu daba ludinga abasebenzi ukuthi baluhlaziye. Izizathu ezingenzeka nazo zibangelwa izinkinga nge-bitumen eguquliwe (ukwakheka: i-asphaltene ne-resin) isitshalo ngokwayo, ngoba i-bitumen evamile nayo inezigaba ezahlukene. Lapho kukhiqizwa i-bitumen eguquliwe, kufanele kuqashelwe ukuthi izinto zokusetshenziswa ezisetshenziswayo yizona ezidingekayo. Ibitumeni elijwayelekile kanye nekhwalithi eqinisekisiwe.
Ibitumen eguquliwe ekhiqizwa imishini yebitumen eguquliwe, ngakolunye uhlangothi, igcina noma ikhuphule ukuhlangana, ipulasitiki kanye ne-fluidity yebitumen yasekuqaleni, ngakolunye uhlangothi, ithuthukisa ukuzinza kwezinga lokushisa (incazelo: izinzile futhi izinzile; alukho ushintsho) i-bitumen ne-Elasticity, engafinyelela inhloso yokuthuthukisa ukusebenza komgwaqo webitumen.
Ngaphezu kwalokho, i-bitumen eguquliwe (ukubunjwa: i-asphaltene ne-resin) yamukela inqubo yokukhiqiza eqhubekayo nesayensi futhi ingakhiqiza ngokuqhubekayo i-polymer modified bitumen efika kumathani angu-30/hora. Kubuye kube umshini oqhubekayo oqhubekayo onomthamo omkhulu wokukhiqiza umshini owodwa. Impahla yebitumen eguqulelwe ngokocansi ilungele ukukhiqizwa kwamaqoqwana amancane naphakathi nendawo emishini yebitumen eshintshiwe ye-emulsified. Ingakwazi ukuhlangabezana nezidingo zezimo ezihlukahlukene zohlelo futhi ikhiqize isitshalo sebitumen esilungisiwe esisebenza kahle emgwaqeni futhi izinzile (incazelo: izinzile futhi izinzile; alukho ushintsho).
