过去在新造、修理客車的铁零件油漆涂飾中,采用油性紅丹底漆。这种紅丹底漆干燥时間慢,在20～25℃条件下,一般需24小时,生产周期太长,严重地影响了生产进度。我厂在青島油漆厂的协助下,进行試制过氯乙烯鉄紅底漆。經多次配方試驗,終于試制成功。通过 In the past in the new, repair the iron parts of passenger car paint finishing, the use of oil red lead primer. This red lead primer drying time is slow, at 20 ~ 25 ℃ conditions, generally takes 24 hours, the production cycle is too long, seriously affecting the progress of production. I plant in Qingdao paint factory with the assistance of trial production of vinyl chloride 鉄 red primer. After repeated formula test, finally trial success. by
