Tasirin sarrafa zafin jiki akan kayan aikin bitumen da aka gyara
A cikin tsarin shirye-shiryen kayan aikin bitumen da aka gyara, kula da zafin jiki yana da mahimmanci. Idan zafin bitumen ya yi ƙasa da ƙasa, bitumen zai yi kauri, ƙasa da ruwa, kuma yana da wahalar yin emulsify; idan zafin bitumen ya yi yawa, a gefe guda, zai sa bitumen ya tsufa. A lokaci guda, yawan zafin jiki na shigarwa da fitarwa na bitumen emulsified zai yi yawa sosai, wanda zai shafi kwanciyar hankali na emulsifier da ingancin bitumen na emulsified. Abin da kowa ya kamata kuma ya fahimta shi ne cewa bitumen wani muhimmin sashi ne na bitumen da aka samu, gabaɗaya yana lissafin kashi 50% -65% na jimlar ingancin bitumen.
Idan aka fesa bitumen da aka yi da shi ko kuma a gauraya, za a cire bitumen ɗin da aka yi masa, sannan bayan ruwan da ke cikinta ya ƙafe, abin da ya rage a ƙasa shi ne bitumen. Saboda haka, shirye-shiryen bitumen yana da mahimmanci. Bugu da kari, ya kamata kowa ya lura cewa lokacin da aka kera shukar bitumen emulsified, dankon bitumen yana raguwa yayin da zafin jiki ya karu. Ga kowane 12 ° C yana ƙaruwa, ƙarfin ɗanɗanonsa kusan ninki biyu.
A lokacin samarwa, tushen bitumen na noma dole ne a fara mai zafi zuwa ruwa kafin a iya aiwatar da emulsification. Domin daidaitawa da ikon emulsification na micronizer, ƙarfin danko mai ƙarfi na tushen bitumen ana sarrafa gabaɗaya ya zama kusan 200 cst. Ƙananan zafin jiki, mafi girman danko, don haka famfo bitumen yana buƙatar haɓakawa. da matsa lamba na micronizer, ba za a iya emulsified; amma a daya hannun, domin kauce wa evaporation da evaporation na ruwa mai yawa a cikin ƙãre samfurin a lokacin samar da emulsified bitumen , wanda zai haifar da demulsification, kuma yana da wuya a zafi namo substrate bitumen da yawa, da Ana amfani da micronizer gabaɗaya. Zazzabi na samfuran da aka gama a ƙofar da fita yakamata su kasance ƙasa da 85 ° C.
