摘要
研究了无钝化热镀锌板的磷化工艺，当温度为10-40℃，游离酸度为0．6-1．1点，总酸度为17-25点，促进剂为2-4点，浸泡处理5-15min，喷淋处理1．5-3．0min时获得质量优良的磷化膜，涂装后漆膜附着力1级，耐冲击性大于50cm，耐中性盐雾试验1000h。
Phosphating process of no passivation hot dip zinc plate was studied. Phosphorization film with good quality could he obtained under the optimum condition that at the temperature of 10-40 ℃, soaked for 5- 15 rain and sprayed for 1.5- 3.0 min, the free acidity was 0.6- 1.1 points, the total acidity was 17 - 25 points and the promoter was 2 - 4 points. The adhesion of coating was grade 1, impact resistance value was more than 50 cm and the time of anti-salt spray was 1 000 hours.
