1. 有機浸滲的意義The meaning of organic infiltration
Metal castings are manufactured by injecting metal in liquid state into a mold, and are widely used because it can produce the same castings in large quantities and cheaply within a certain quality range.
In recent years, the development of casting technology has been very significant, and it is mostly used in the production of automobile engines for the purpose of mass production. At the same time, the problems that need to be solved are also widely known. One of the problems is the formation of micropores and blisters due to volume shrinkage as the metal solution solidifies. After repeated processing of castings with micropores, there may be leakage of liquid and gas. If the shape of the designed casting is complex, it is not easy to prevent the generation of micro-holes, and it will directly become an unqualified product. If the manufacturing cost of the qualified product is increased, it will affect the arrangement of the production plan.
If the leaking castings are treated with organic infiltration, the pass rate can be almost 100%, which can not only reduce the manufacturing cost but also improve the quality and production quantity. Using the organic impregnation solution produced by our company can make the unqualified castings qualified, and the processing time is short and the cost is low.
2.有機浸滲劑90C的使用工目的Purpose of use of organic impregnating agent 90C
The effect of treatment with organic infiltrating agent (organic infiltrating agent 90C) is shown below.
A) Endowed with pressure resistance and sealing function: filling the impregnating liquid into the micropores that communicate with the inside and outside can play a sealing role.
B) Endows with corrosion-resistant function: blocking connected or non-connected micropores can prevent internal corrosion.
C) Pretreatment of synthetic treatment: filling the recessed treatment surface to prevent discoloration, corrosion, peeling, and swelling.
D) Improve the cutting performance: it is filled with the infiltrating liquid inside the metal, which can act as a lubricant.
E) Improve physical strength: the impregnation liquid fills and blocks the inside of the micropore, and the gap reduces the physical strength
can be improved.
F) Improve insulation: block internal voids, which can increase the resistance value for protection.
4.90C的特點Features of 90C
→雖然在處理裝置的設計上會有所不同，但是，在進行浸滲處理時， 周圍常?；\罩著浸滲液霧，有時浸滲液還可能直接接觸到皮膚。即使 這樣，您也能很放心地使用該浸滲液。
90C is an organic infiltrant that minimizes the unreasonable concerns of shop operators. From an operator's point of view, the infiltrated material has the following favorable characteristics in terms of quality.
A) It is an organic impregnation liquid composed of two liquids, the main agent and the curing agent.
→Because it is composed of two kinds of liquids, its preservation performance is significantly improved. Unlike a single liquid, abnormal quality occurs when a new liquid is stored. In addition, the two liquids have good mutual solubility, and it is very easy to mix, the mixed impregnation liquid is very stable, and the storage method is also very simple.
B) The impregnating liquid is water-soluble, and the remaining impregnating liquid adhering to the impregnated object can be washed away with water.
→There is no need to use a troublesome organic solvent, and since no surfactant is added, it will not adversely affect the cured product.
C) A low-viscosity design is adopted in the design, so as to recover the remaining impregnating liquid in large quantities as soon as possible.
→ Usually the infiltrated material is immersed in a large impregnation tank, if possible to recycle
The remaining impregnating liquid adheres to its surface, which can reduce the cost.
D) Since the boiling point of the impregnating liquid in the vacuum state is very high, the load on the vacuum pump can be reduced.
→The boiling point of the liquid will drop sharply in a vacuum state below 10torr (10AHg).
The boiling point of 90C under reduced pressure is very high and will not burden the vacuum pump.
E) Consideration is also given to safety and hygiene.
→Although there are differences in the design of the treatment device, when the impregnation treatment is performed, the surrounding is often surrounded by a mist of impregnating liquid, and sometimes the impregnating liquid may directly contact the skin. Even so, you can use the impregnating fluid with confidence.
F) Suitable for various materials
→Mainly aluminum, bronze, cast iron, zinc, sintered products, magnesium and other materials can be infiltrated.
G) High filling efficiency can be achieved
→Although the conditions of micropores are not the same, usually the recovery rate of impregnation treatment can reach almost 100%. The diameter of the remedial pores ranges from a few UM to several hundreds of UM. Even the large-diameter defect holes that can be seen by the eye can be remedied under certain conditions.
