Hydrotalcite introduction

Hydrotalcite Mg ₄ .3Al ₂ (OH) ₁₂ .6CO ₃ - mH ₂ O
DHT-4A is a synthetic hydrotalcite compound that has recently been further used in the field of plastics processing, such as a stabilizer for the production of polyolefins (halogen scavengers).
The natural hydrotalcite {Mg ₆ A _l2 (OH) ₁₆ CO ₃ - 4H ₂ O} has a small amount of sediment in the Urals of Russia and the Snarum of Norway. In 1966, Japan Concord Chemical Industry Co., Ltd. successfully synthesized hydrotalcite for the first time in the world. The first discovered the use of hydrotalcite as an antacid in the pharmaceutical industry. This product has been sold worldwide through some famous pharmaceutical factories.
The chemical composition is Mg ₃ [Si ₄ O ₁₀ ](OH) ₂ , and the crystal belongs to the triclinic layered structure silicate mineral. Pseudo-hexagonal sheet-like single crystals are rare, generally in the form of dense blocks, leaves, fibers or radial aggregates. White or various light colors, the streaks are often white, fat luster (blocky) or pearl luster (sheet aggregate), translucent. Mohs hardness 1, specific gravity 2.6-2.8. One set is extremely cleavable and the sheet is flexible. It has a slippery feel, strong insulation and strong insulation.
Identification features: According to the light color, low hardness (nail can be scored), with a sense of slippery, a set of extremely complete cleavage and other characteristics, can be distinguished from similar minerals such as pyrophyllite and massive serpentine.
Talc is a hydrothermal alteration mineral. Magnesium- rich minerals often turn into talc after hydrothermal alteration, so talc is often an illusion of minerals such as olivine, pyroxene, hornblende, and tremolite . Talc is widely used in paper, ceramics, rubber, paint, refractory equipment, textiles, dyes, foundry and pharmaceutical industries. The blocky talc is soft, smooth and soft, and is used to engrave handicraft materials.

â‘ Hardness:

Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.

â‘¡Pressure resistance:

The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.

â‘¢Prevention of oil leakage:

Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.
