Pehea e koho ai i nā surfactants no ka hoʻohana ʻana i ka ʻaila kaumaha a me ka ʻaila maka waxy
1. Nā Surfactants no ka unuhi ʻana i ka ʻaila kaumaha Ma muli o ke kiʻekiʻe o ka viscosity a me ka wai ʻole o ka ʻaila kaumaha, ua kū i nā pilikia he nui kona hoʻohana ʻana. No ka hoʻihoʻi ʻana i kēlā ʻaila kaumaha, hoʻokomo pinepine ʻia nā hopena wai o nā surfactants i loko o ka lua. Hoʻololi kēia kaʻina hana i ka hea viscosity kiʻekiʻe...E heluhelu hou aku -
