模具喷涂作业常见问题及解决方法

来源:http://www.sdlqmj.com 日期:2019-04-01 发布人:admin 浏览次数:
1.现象:起粒。缘由:作业现场不洁,灰尘混入油漆中;油漆分配好后放太久,油漆与固化剂已产生共聚微粒;喷枪出油量太小,气压太大,令油漆雾化不良或喷枪离物面太近。处理办法:清洁喷漆室,盖好油漆桶;油漆分配好,不宜放太久;调整喷枪,以使其处于佳工作状态,肯定枪口间隔物面20-50CM为宜。
1. Phenomenon: granulation. Reasons: unclean work site, dust mixed into the paint; paint distribution after a long time, paint and curing agent have produced copolymer particles; spray gun out too small amount of oil, too high pressure, make paint atomization bad or spray gun away from the surface too close to the treatment methods: clean spray room, cover the paint bucket; paint distribution is good, should not be put too long; adjust spray gun, so that it is in the best working condition, Surely 20-50CM muzzle spacer surface is suitable.
2.现象:垂流。缘由:稀释剂过量令油漆粘度太低,失去粘性;出油量太大,距物面太近或喷运转太慢;每次喷油量太多太厚或重喷距离时间太短;物面不平,特别流线体外形易垂流处理办法:按请求配比;控制出油量,确保喷漆离进步喷枪运转速度;每次喷油不宜太厚,分两次好控制距离喷漆时间;控制出油量,减少漆膜厚度;按运用阐明配比。
2. Phenomenon: Vertical flow. Reasons: excessive diluent makes paint viscosity too low and lose viscosity; too much oil is produced, too close to the surface or too slow spray operation; too much oil is sprayed each time or too short re-spray distance; uneven surface, special streamline body shape is easy to vertical flow treatment method: according to the request ratio; control the amount of oil to ensure that spray from the progressive spray gun running speed; each spray should not be too thick, divided into two times It is better to control the distance of painting time, control the amount of oil, reduce the thickness of paint film, and formulate according to the application.
3.现象:桔皮。缘由:固化剂太多,令漆膜枯燥太快反响猛烈;喷涂气压太大,吹皱漆膜致使无法流平;作业现场气温太高,令漆膜么应猛烈处理办法:按运用阐明配比;调整气压,不可太大;留意现场温度,可添加慢干稀释剂抑止枯燥速度广州喷涂加工。

3. Phenomenon: orange peel. Reasons: too many curing agents make the paint film dull, too fast and strong response; too much spraying pressure, wrinkling film can not be leveled; too high temperature at the work site, so that the paint film should be treated vigorously: according to the application of the ratio; adjust the pressure, not too large; pay attention to the site temperature, can add slow-drying diluent to suppress the drying speed of Guangzhou spraying processing.
4.现象:泛白。缘由:作业现场气温湿度大,漆膜反响猛烈,可能和空气中水份分离产生泛白现象;固化剂过量,一次喷涂太多太厚处理办法:留意现场湿度,可添加防白水,阻止泛白现象发作;按比例调制,一次喷涂不可太厚。
4. Phenomenon: Whiteness. Reasons: the temperature and humidity of the work site are high, and the paint film reacts violently, which may cause the whitening phenomenon separated from the moisture in the air; the treatment method of excessive curing agent and too much and too thick spraying at one time: pay attention to the field humidity, add anti-whitening water to prevent the occurrence of whitening phenomenon; proportionally modulate, the spraying can not be too thick at one time.
