精密铸造trasys脱模剂


Stoner B251 Citrus Pattern Wash




橘子模式洗净

B251通常用于大量的清洗,它可以稀释- 你可以去以1:1分量進行,較為经济一點,但这會减轻了去蚀作用。B251浸入长达30秒,然后用清水漂洗(或浸渍)。没有必要用去离子水。尝试直接使用,观察清洗/去蚀的结果,然后调整稀释比例或所需浸渍时间。

B251溶剂會去除脫模劑和表面图案。去蚀可有助表面變得粗糙,允许浸渍当浆料更好地附着在粗糙的表面。使用B251跟周邊温度沒有什麼影响,但是,使用B251时,蜡模较热,获得更多的去蚀,这样你就可以按你的需要去稍微控制去蚀的程度。然而,你需要确保蜡面已经冷却到室温,可能等待至少一个小时,以确保蜡不会在浸入浆之前扩大或收缩。

我们有一些客户,每天都要處理250-300個模具。他们可能每天要改变冲洗模式,但橘子模式洗净就可以提供一個較佳方案去改变處理方式。

虽然B251是冻融稳定的,但B251不应该被允许冷冻。B251是微乳液,如果保持关闭,并储存在室温下,可最少保存6个月,甚至长达一年。

清洗和去蚀刻图案,消除硅氧烷,指纹,灰尘和可引起的污染物。这种高度可稀释,水性清洁剂,包裝提供有5加仑和55加仑。从柑橘类水果中提取的,因此留下了香的气味。

Citrus Pattern Wash

B251 is typically used at full strength for maximum cleaning and etching performance. It can be diluted – you can go as far as 1:1 for improved economy but this lessens the etching action. Patterns are normally dipped into B251 for up to 30 seconds and then rinsed (or dipped) clean with water. No need for deionized water. Try using it straight, observe cleaning/etch results and then adjust dilution or dip time for desired performance.

 

The solvents in the B251 will clean off the release agent as well as etch the wax pattern.  Etching provides a rougher surface on the wax pattern which allows the slurry to adhere better to the wax pattern when dipped.  I don’t believe that there is great temperature effect on using the B251, however, I believe you can get more etching using the B251 when the wax pattern is hotter and less when it is cooler, so you can somewhat control the degree of etching you desire.  You do however need to be sure the wax pattern has cooled to ambient temperature, probably at least an hour of sitting, to be sure that the wax is not expanding or contracting prior to dipping into the slurry.

 

We have customers who pour 250-300 molds per day and switch out every 1 ½-2 weeks.  They might change their rinse water every day, but the pattern wash is more based on a “feel” basis.  If it felt like it was getting thick and slimy they would change it.  If it appeared to not be etching as well they changed it.

 

B251 should not be allowed to freeze, although it is freeze-thaw stable. B251 is a micro emulsion and will be stable for 6 months minimum and possibly up to a year if kept closed and stored at room temp.

 

Cleans and etches wax patterns, eliminating silicone, fingerprints, dust and contaminants which can cause imperfections. This highly-dilutable, water-based cleaner is available in 5-gallon and 55-gallon units. Made from extract of citrus fruits. Leaves a pleasant scent.
