Rubber mold cleaning, silicone mold cleaning solution

Here is an article about silicone mold cleaning solution, tell you how to cleaning rubber mold, let us see it. 

The molds is very important of use to make PVC or Silicone production. When you make a production, like use dispensing machine, hydraulic machine, embossing machine,etc. all machines need it. So after use, how to cleaning it, then reuse it. 

( Removing dirt from molds has always been a headache in the rubber and silicone industry. Because vulcanization of rubber and silicone needs to be done at high temperature, some oil and chemicals remain in the mold for a long time. Timely and high temperature coking is required to form stubborn fouling.
Rinse mold water with LW303 to remove all dirt in an instant. LW303 ultra-modified washing water contains special accelerators and special detergents for molds. Conventional detergents often lack cleaning power. It must be combined with a metal brush or sandblasting to remove stubborn dirt on the mold, so it often causes damage to the mold.
To use this product, spray a small amount of stock solution or diluent on the surface of the mold. In a very short time, the stubborn dirt can be completely removed without damaging the mold and prolonging the service life. Excellent performance in rubber product mold cleaning, tire mold cleaning, rubber seal mold cleaning, silicone product mold cleaning.

The characteristics of using washing water:
1. LW-303 [washing water] high-quality mold cleaning agent, any serious mold dirt can be completely removed instantly, easy to use, will not damage the mold, and can also prolong the service life of the mold.

advantage:
1. The high-temperature mold is directly cleaned, and the dirt is removed instantly, without stopping the machine, and does not affect production. After descaling, the mold is clean and bright, which can improve product quality and increase the out-of-city rate.
2. This product is a high-concentration water-soluble liquid, which can be diluted with appropriate amount of water according to the degree of mold pollution. It is very economical and practical, and can directly reduce production costs. Can also remove oil stains or light rust.

use:
1. Dispersion method: Please use a small amount of stock solution or diluent to smear or smear on the mold at high temperature. After 2-10 minutes, the dirt will soften and dissolve. Rinse the mold with water immediately before it dries. The mold temperature is above 95°C.
2. Immersion method: The iron bath contains liquid or thinner, and after soaking, heat it to about 95°C for about 2-3 minutes. Or put it directly into a high-temperature mold in a solution at room temperature, soak it for 2-3 minutes and start taking it, and then rinse it with clean water.

Precautions:
1. This product is an alkaline solution. Wear gloves when working.
2. If your hands or skin come in contact with the solution, wash with water.
3. Because it is an alkaline substance, aluminum molds cannot be used.

Reasons for use Common problems and solutions:
1. Mold cleaning is not clean If the mold temperature is too low or too high (85-120 degrees), the adhesion of the mold water to the mold surface is insufficient. The mold scale is too thick to be completely removed in one go. The reaction time of the mold water on the mold surface is too short to soften free dirt. Incomplete decontamination after rinsing.
2. The mold is rusted after cleaning, the reason is that the fresh metal surface will be exposed after the chrome-plated mold is cleaned, which interacts with the oxygen in the air and the electrolyte in the cleaning agent. Solution: Rinse off the residual cleaning agent as much as possible, apply emulsified oil or release agent to protect the new surface before the mold dries, and use a variety of cleaning agents containing corrosion inhibitors. The mold sticking phenomenon occurs after cleaning, which may be due to the insufficient finish of the mold processing. When the dirt on the mold is completely removed, an "anchor" effect is formed between the groove and the rubber. Appropriate use of external mold release agents can alleviate this phenomenon. The metal surface is lightly activated after cleaning and bonds lightly to the rubber just like a freshly used mold. Appropriate use of external mold release agents can alleviate this phenomenon. If the mold is not cleaned thoroughly, the alkaline substances in the cleaning agent may interact with the vulcanizing agent system (such as peroxide) in some formulations, resulting in salt stains on the surface of the product and temporary adhesion. )
