Emulsion bitumen bụ emulsion ọhụrụ kpụrụ site n'ibu ọrụ nke asphalt na emulsifier aqueous solution.
A na-ekewa bitumen emulsion dị ka ihe dị iche iche nke bitumen emulsifier ji mee ihe: cationic emulsion bitumen, anionic emulsion bitumen na nonionic emulsion bitumen.
Ihe karịrị 95% nke iwu okporo ụzọ na-eji cationic emulsion bitumen. Kedu ihe kpatara bitumen cationic emulsion ji nwee uru dị otú ahụ?
1. Nhọrọ nke mmiri dị oke obosara. Bitumen, mmiri na bitumen emulsifier bụ isi ihe maka emulsion bitumen. Ekwesịrị iji mmiri dị nro kwadebere bitumen Anionic emulsified na enweghị ike ịgbanye ya na mmiri siri ike. Maka bitumen cationic emulsion, ị nwere ike ịhọrọ bitumen emulsion maka mmiri siri ike. Ị nwere ike iji mmiri siri ike iji dozie ihe ngwọta nke emulsifier, ma ọ bụ ị nwere ike ịgbanye ya ozugbo.
2. Mfepụta dị mfe na nkwụsi ike dị mma. Nkwụsi ike nke anions adịghị mma na admixtures kwesịrị ịgbakwunye iji hụ na nkwụsi ike nke ngwaahịa emechara. N'ọtụtụ ọnọdụ, bitumen cationic emulsion nwere ike ịmepụta bitument emulsion kwụsiri ike na-agbakwunyeghị mgbakwunye ndị ọzọ.
3. Maka cationic emulsion bitumen, e nwere ọtụtụ ụzọ iji dozie ọsọ demulsification na ọnụ ahịa dị ala.
4. Cationic emulsified asphalt ka nwere ike ịrụ dị ka ọ dị na mbụ na oge iru mmiri ma ọ bụ obere okpomọkụ (n'elu 5 ℃).
5. Ezi adhesion na nkume. Ngwakọta bitumen cationic emulsion na-ebu ụgwọ cationic. Mgbe a na-akpakọrịta na nkume, a na-etinye ihe ndị ahụ asphalt ngwa ngwa n'elu nkume n'ihi mmasị nke ihe ndị ọzọ. A na-eji ya na micro surfacing na slurry seal.
6. The viscosity nke cationic emulsion bitumen dị mma karịa nke anionic emulsion bitumen. Mgbe ị na-ese ihe, cationic emulsion bitumen siri ike karị, yabụ ị nwere ike ịhọrọ ịgba ya. N'ụzọ megidere nke ahụ, bitumen emulsion anionic dị mfe agba. Enwere ike iji ya dị ka mmanụ oyi akwa na-abanye n'ime ya na mmanụ oyi akwa na-egbuke egbuke na-ewu ihe mgbochi mmiri na ighe okporo ụzọ.
7. Cationic emulsion bitumen na-emepe okporo ụzọ ngwa ngwa.
