Tsarin samarwa ya haɗa da: dumama zafin bitumen da maganin sabulu, daidaita ƙimar maganin sabulun pH, da sarrafa yawan kwararar kowane bututu yayin samarwa.
(1) Zafin zafi na bitumen da maganin sabulu
Bitumen yana buƙatar samun babban zafin jiki don cimma kyakkyawan yanayin kwarara. Rushewar emulsifier a cikin ruwa, haɓaka aikin maganin sabulu na emulsifier, da rage tashin hankali na tsaka-tsakin ruwa-bitumen yana buƙatar maganin sabulu ya kasance a wani zazzabi. A lokaci guda, zafin jiki na emulsified bitumen bayan samarwa ba zai iya zama sama da 100 ℃, in ba haka ba zai haifar da tafasar ruwa. Yin la'akari da waɗannan abubuwan, an zaɓi zafin zafin jiki na bitumen don zama 120 ~ 140 ℃, zafin zafin sabulun bayani shine 55 ~ 75 ℃, kuma yanayin zafin bitumen na emulsified bai wuce 85 ℃ ba.
(2) Daidaita maganin sabulun pH darajar
Emulsifier kanta yana da ɗan acidity da alkalinity saboda tsarin sinadarai. Ionic emulsifiers narke cikin ruwa don samar da maganin sabulu. Ƙimar pH tana rinjayar aikin emulsifier. Daidaita zuwa ƙimar pH mai dacewa yana haɓaka aikin maganin sabulu. Wasu emulsifiers ba za a iya narkar da su ba tare da daidaita ƙimar pH na maganin sabulu ba. Acidity yana haɓaka aikin emulsifiers na cationic, alkalinity yana haɓaka aikin emulsifiers anionic, kuma ayyukan nonionic emulsifiers ba shi da alaƙa da ƙimar pH. Lokacin amfani da emulsifiers, ƙimar pH yakamata a daidaita daidai da takamaiman umarnin samfur. Acid da alkalis da aka fi amfani da su sune: hydrochloric acid, nitric acid, formic acid, acetic acid, sodium hydroxide, soda ash, da gilashin ruwa.
(3) Sarrafa bututun mai
Gudun bututun bitumen da maganin sabulu yana ƙayyade abun cikin bitumen a cikin samfurin bitumen da aka yi. Bayan da aka gyara kayan aikin emulsification, ƙarar samarwa yana da mahimmanci. Ya kamata a ƙididdige yawan kwararar kowane bututun kuma a daidaita shi gwargwadon nau'in bitumen da aka yi. Ya kamata a lura cewa jimlar kwararar kowane bututun ya zama daidai da ƙarar samar da bitumen da aka yi.
