Menene cikakkun matakai da kwararar tsari na kayan aikin bitumen emulsified?
Ana iya raba tsarin samar da bitumen da aka haɗa zuwa matakai huɗu masu zuwa: shirye-shiryen bitumen, shirye-shiryen sabulu, emulsification bitumen, da ajiyar emulsion. Matsakaicin madaidaicin emulsified bitumen kanti ya kamata ya kasance a kusa da 85 ° C.
Dangane da yin amfani da bitumen na emulsified, bayan zaɓar alamar bitumen da ta dace da alamar bitumen, tsarin shirye-shiryen bitumen shine tsarin dumama bitumen da kiyaye shi a yanayin zafi mai dacewa.
1. Shiri bitumen
Bitumen shine mafi mahimmancin bangaren bitumen da aka ƙera, gabaɗaya yana lissafin kashi 50% -65% na jimillar bitumen emulsified.
2.Shirin maganin sabulu
Dangane da bitumen emulsifier da ake buƙata, zaɓi nau'in emulsifier da ya dace da sashi da nau'in ƙari da sashi, sannan shirya maganin ruwa mai ruwa mai emulsifier (sabulu). Dangane da kayan aikin bitumen emulsified da nau'in emulsifier, tsarin shirye-shiryen na maganin ruwa (sabulu) na emulsifier shima ya bambanta.
3. Emulsification na bitumen
Sanya madaidaicin rabo na bitumen da ruwan sabulu a cikin emulsifier tare, kuma ta hanyar tasirin injina kamar su matsa lamba, shear, niƙa, da sauransu, bitumen zai samar da nau'i iri ɗaya da lallausan barbashi, waɗanda za'a tarwatsa su a ko'ina cikin ruwan sabulu don samar da aljihun ruwa. Oil bitumen emulsion.
Kula da zafin jiki yayin tsarin shirye-shiryen bitumen yana da matukar muhimmanci. Idan bitumen zafin jiki ya yi ƙasa sosai, zai sa bitumen ya sami babban danko, wahalar kwarara, don haka matsalolin emulsification. Idan zafin bitumen ya yi yawa, zai haifar da tsufa na bitumen a gefe guda, kuma yana yin bitumen emulsified a lokaci guda. Zazzabi na kanti ya yi yawa, wanda ke shafar kwanciyar hankali na emulsifier da ingancin bitumen emulsified.
Yawan zafin jiki na maganin sabulu kafin shigar da kayan aikin emulsification gabaɗaya ana sarrafa shi tsakanin 55-75 ° C. Yakamata a samar da manyan tankunan ajiya da na'urar motsa jiki don motsawa akai-akai. Wasu emulsifiers waɗanda suke da ƙarfi a cikin ɗaki suna buƙatar dumama da narkewa kafin shirya sabulu. Saboda haka, shirye-shiryen bitumen yana da mahimmanci.
4. Ajiya na emulsified bitumen
Emulized bitumen yana fitowa daga emulsifier kuma ya shiga cikin tankin ajiya bayan sanyaya. Wasu hanyoyin samar da ruwa mai ruwa na emulsifier suna buƙatar ƙara acid don daidaita ƙimar pH, yayin da wasu (kamar gishirin ammonium quaternary) ba sa.
Don rage rage rarrabuwar bitumen emulsified. Lokacin da aka fesa bitumen da aka yi da shi ko kuma a gauraya, za a cire bitumen da aka yi da shi, kuma bayan ruwan da ke cikinta ya kafe, abin da ya rage a hanya shi ne bitumen. Don ci gaba da ci gaba ta atomatik na kayan aikin samar da bitumen, kowane ɓangaren sabulu (ruwa, acid, emulsifier, da dai sauransu) ana kammala ta atomatik ta shirin da kayan aikin samarwa da kansu suka tsara, muddin an tabbatar da samar da kowane abu; don kayan aikin ci gaba na ɗan lokaci ko na ɗan lokaci yana buƙatar shirya sabulu da hannu bisa ga buƙatun ƙira.
