Kedu ka esi eme Bitumen Emulsion?
A na-emepụta emulsion bitumen na usoro abụọ dị mfe. A na-ejikọta mmiri mbụ na ihe emulsifying na ihe ndị ọzọ na-emepụta ihe. Mgbe ahụ, a na-eji igwe igwe colloidal jikọta mmiri, emulsifier, na bitumen. Dabere na njedebe nke emulsion bitumen, a na-agbakwunye ọnụọgụ bitumen na ngwakọta. Mgbe a na-eme emulsifier dị ka ngwaahịa isi, enwere ike iji ya n'etiti 60-70%.

Ọnụ ego bitumen a na-agbakwunye na ngwakọta dị n'etiti 40% na 70%. Igwe igwe kolloidal na-ekewa bitumen n'ime ụmụ irighiri ihe. Nkezi nha droplet bụ ihe dịka 2 microns.

A na-ekewa emulsions bitumen n'ụzọ bụ isi n'ime otu atọ ndị a dabere n'ụdị ụgwọ elu:
Anionic Bitumen Emulsion
Cationic Bitumen Emulsion
Emulsion na-abụghị ionic bitumen

A na-ebubo irighiri bitumen electro-negatively ma ọ bụrụ na emulsion anionic bitumen, ebe n'ihe banyere emulsions cationic, ihe ndị bituminous bụ electro-positive. Taa, a na-ejikarị cationic emulsion nke bitumen eme ihe. Dabere na ihe mejupụtara mineral nke mkpokọta eji ewu ụlọ, ọ dị mkpa iburu emulsion nke bitumen. Ngwakọta nke mkpokọta na-aghọ electro-negatively ebubo n'ihe banyere silica-ọgaranya aggregates. Ya mere, ekwesịrị ịgbakwunye emulsion cationic.
