There is no need to add talcum powder to the release agent. Unless your craft is special. It looks like there's something wrong with your production process.
Suggestion: a water-based, waste oil plus emulsifier of-15 plus water. 1:3 or 1:6 with water, depending on the use environment. Milky. Long-term internal layering. It is suitable for beam factory, aluminum mold, wood mold, cement products and so on.
2. For oily ones, add emulsifier of-20 to waste oil and water, 1:3 or 1:4 to water. Blackish-gray or earthy yellow.
It is suitable for steaming and curing aerated blocks, pipe pile factories, etc.

It would be nice to add a little finer, and it will not precipitate much, of course, it also depends on the density of your solvent and the time it has been placed.

I don't know what you're using it for?
For the use of these two additives, it is recommended that you consult their technicians on the official websites of some release agent brand manufacturers, and there will be a more detailed and professional reply.

Inorganic release agent: talc powder is mainly used as a release agent for film and semi-finished products in rubber processing. The main use of talcum powder is to fill the cost, reduce costs and enhance performance.

No, because there are no environmental protection regulations for concrete release agents, so they are not suitable for interior wall painting and may cause harm to human health.
Production process principle:
The release agent is a 0 w type emulsion formed by the processing of polymer mineral oil, resin, surfactant and other auxiliary materials through a specific process. The surface tension of water and oil substances is quite different, it is difficult to miscible with each other, even if the oil substances are dispersed in the water under the strong action, when the oil particles collide with each other due to microscopic movement, they will still automatically gather together and gradually separate from the water, so as to greatly reduce the effective isolation and rust prevention performance, in order to solve this problem, by calculating the HLB value, select a suitable surfactant, which has two groups of hydrophilic group and lipophilic group, under specific production process conditions, the oil will fully react to generate a stable O W This stable emulsion can form a continuous and uniform isolation protective layer on the template, so as to play a good isolation role. Because there is a layer of water film on the periphery of the isolation layer, the oil substance and the concrete are not in direct contact, so there is no pollution.
Concrete separator is a new type of product, which is mainly used in the construction of modern steel formwork.

The problem of reclaimed adhesive roller has been encountered by many rubber products enterprises, some companies have solved it, and some are still troubled by it, the reason for the sticky stick caused by reclaimed rubber is: reclaimed rubber is high, the glue content is high, and the sticky roller and sticky mold staring plexus are increasing. When reclaimed rubber is regenerated, it needs to be desulfurized and degraded at high temperature, and serious degradation or too much softener is added, etc., which will cause the reclaimed rubber to be very sticky.
Here I will talk about my method for your reference, I hope to help rubber products enterprises, if you have a better way, you are welcome to correct. 1.Adjust the roller spacing of the mill to about multiple of the original.
2.It is enough to control the roll temperature of the open mill, which is generally controlled below 85 degrees Celsius. 3.
Appropriate addition of cis, we all know that the wax is used alone when the roller is serious, but it is used in the rubber of the sticky roller to improve the roller removal property is very helpful. 4.Fill 10 parts of auxiliary talcum powder, talc itself has good demoulding, but using too much will make rubber products brittle, so in the addition of talcum powder according to the proportion of reclaimed rubber to add 5
Add a fixed amount of stearic acid and paraffin to help release the mold. 6.5 parts of black ointment can be added, due to the regeneration of the liquid glue in the previous use of the aging process and the regeneration desulfurization process led to a significant reduction in molecular weight, resulting in a large number of low components, thus making the sticky roller serious, and the black ointment has the adsorption effect of low molecular substances.

Hello dear! We'll be happy to answer for you. How many copies of talcum powder to play a role in demoulding in rubber Answer:
Hello dear, in the EPDM reclaimed rubber butyl rubber waterproof material rubber, talcum powder can be appropriately added about 30 copies. Talcum powder has low performance and good performance, which can improve the performance of rubber and reduce production costs. The English name of talcum powder is pulvistalci, which is white or off-white, fine, non-sandy powder, and has a greasy feeling to the touch.
Odorless, tasteless. This product is insoluble in water, dilute mineral acid or dilute hydroxide alkali solution. It can be used medicinally.
The main ingredient is talc. English Liang Hand Name: Talc Cas No:
14807-96-6 Molecular weight: Chinese alias: water oak magnesium silicate ultrafine powder.

Happy. How many parts of talcum powder are needed to release from the rubber.
Hello dear, I am a gold medal mentor of cooperation, I have provided a total of 1w people with a cumulative service time of more than 3000 hours!

Flowers are in a loss] [Happy.
Hello, talcum powder needs more than 1000 parts to release from the rubber.
Hello, dear, the ratio of rubber talc is 1 ratio is appropriate, and talc (calcium carbonate) is the industry standard of 900 mesh drops. The ratio of PVC and talc powder used in the extrusion grade is 1 ratio, and the mesh of talc is more than 1000 to ensure the quality of the product.
I hope my answer is helpful to you, and please give a thumbs up (comment on the bottom left Jane Tsai corner), looking forward to your like, your efforts are very important to me, and your support is also the driving force for my progress.

Hello dear, the commonly used grinding aids in cement are triethanolamine (TEA) and so on. To counteract the effect of these grinding aids on cement, this can be achieved by adding some admixtures as substitutes. You can add some additives such as moderators, plasticizers, oxygen dopants, etc. to improve concrete properties, thus reducing the impact of grinding aids on concrete. >>>More
Hello, my question I suggest to consider the problem of flocculant first, the selection of flocculant can directly affect the effect of sludge pressing of plate and frame machine. If the selection is good, the effect of flocculation and sedimentation of coal washing water is obvious and fast. As a result, the time for sludge pressing is shortened. >>>More
Summary. Aerated concrete is a light porous silicate product made of siliceous materials (sand, fly ash and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with gassing agent (aluminum powder), through batching, mixing, pouring, pre-cursing, cutting, autoclaving, curing and other processes. Because it contains a lot of it after it is released, the above is mine. >>>More
