Kedu usoro zuru ezu na usoro usoro nke ngwa bitumen emulsified?
Enwere ike kewaa usoro mmepụta nke emulsified bitumen n'ime usoro anọ ndị a: nkwadebe bitumen, nkwadebe ncha, emulsification bitumen, na nchekwa emulsion. Okpomọkụ kacha mma emulsified bitumen kwesịrị ịdị ihe dịka 85 Celsius.
Dị ka ojiji nke emulsified bitumen si dị, mgbe ahọpụtara akara na akara bitumen kwesịrị ekwesị, usoro nkwadebe bitumen bụ usoro ikpo ọkụ bitumen na idobe ya na okpomọkụ kwesịrị ekwesị.
1. Nkwadebe nke bitumen
Bitumen bụ akụkụ kachasị mkpa nke emulsified bitumen, na-azakarị 50%-65% nke mkpokọta bitumen emulsified.
2.Nkwadebe ngwọta ncha
Dị ka bitumen emulsified achọrọ, họrọ ụdị emulsifier kwesịrị ekwesị na usoro onunu ogwu yana ụdị mgbakwunye na usoro onunu ogwu, ma dozie emulsifier aqueous solution (ncha). Dabere na akụrụngwa bitumen emulsified na ụdị emulsifier, usoro nkwadebe nke ngwọta mmiri (ncha) nke emulsifier dịkwa iche.
3. Emulsification nke bitumen
Tinye ihe ezi uche dị na ya nke bitumen na ncha mmiri n'ime emulsifier ọnụ, na site n'ibu mmetụta dị ka pressurization, ịkpacha ihe, egweri, wdg, bitumen ga-etolite edo na mma irighiri ihe, nke a ga-agbasasị kwụsie ike na evenly na ncha mmiri mmiri ka. na-etolite akpa mmiri. Emulsion mmanụ bitumen.
Njikwa okpomọkụ n'oge usoro nkwadebe bitumen dị ezigbo mkpa. Ọ bụrụ na ọnọdụ okpomọkụ bitumen dị oke ala, ọ ga-eme ka bitumen nwee nnukwu viscosity, ihe isi ike na-asọba, ma si otú a na-enwe nsogbu emulsification. Ọ bụrụ na okpomọkụ bitumen dị oke elu, ọ ga-eme ka ịka nká nke bitumen n'otu aka, ma meekwa bitumen emulsified n'otu oge. Okpomọkụ ọpụpụ dị oke elu, nke na-emetụta nkwụsi ike nke emulsifier na ogo nke emulsified bitumen.
A na-achịkwa okpomọkụ nke ngwọta ncha tupu ịbanye ngwa emulsification n'etiti 55-75 ° C. Ekwesịrị ịkwado tankị nchekwa buru ibu na ngwaọrụ na-akpali akpali iji kpalite mgbe niile. Ụfọdụ emulsifiers ndị siri ike na ụlọ okpomọkụ kwesịrị ikpo ọkụ na gbazee tupu ịkwadebe ncha. Ya mere, nkwadebe nke bitumen dị oké mkpa.
4. Nchekwa nke emulsified bitumen
Bitumen nke emulsified na-apụta na emulsifier wee banye na nchekwa nchekwa mgbe ọ dị jụụ. Ụfọdụ emulsifier mmiri ngwọta kwesịrị ịgbakwunye acid iji dozie uru pH, ebe ndị ọzọ (dị ka quaternary ammonium salts) adịghị.
Iji belata nkewa nke emulsified bitumen. Mgbe a na-efesa bitumen emulsified ma ọ bụ gwakọta ya, a na-ewepụ bitumen emulsified, na mgbe mmiri dị na ya pụta, ihe fọdụrụ n'ezie n'okporo ụzọ bụ bitumen. N'ihi na n'ụzọ zuru ezu akpaka na-aga n'ihu emulsified bitumen mmepụta ngwá, onye ọ bụla akụkụ nke ncha (mmiri, acid, emulsifier, wdg) na-akpaghị aka emecha site na mmemme setịpụrụ site mmepụta ngwá n'onwe ya, ọ bụrụhaala na ọkọnọ nke ọ bụla ihe onwunwe na-hụ na; maka obere ihe na-aga n'ihu ma ọ bụ nke na-adịte aka na-emepụta ihe na-achọ nkwadebe nke ncha dịka usoro chọrọ.
