In the production of pharmaceutical preparations, such as tablets, capsules, granules, etc., activated molecular sieve powder desiccant can be added to the packaging to make composite packaging materials, absorb moisture in the packaging, and prevent drugs from getting damp and deteriorating during storage.
Two-component polyurethane adhesive is composed of component A (isocyanate component) and component B (polyol component). It has excellent properties such as good wear resistance, chemical resistance, and adhesion, and is widely used in coatings, adhesives, foams, etc. However, during production and use, two-component polyurethane is easily affected by moisture, resulting in bubbles and affecting product performance.
The effect of moisture on two-component polyurethane adhesive is mainly reflected in the following aspects:
Reduced Bonding Strength: Moisture affects the bonding properties of two-component polyurethane and reduces the bonding strength
Reduced Reaction Speed: Moisture reacts with the isocyanate component, reducing the content of effective components and affecting the curing speed.
Reduced Hardness: Moisture participates in the curing reaction, and the resulting product has a lower hardness, affecting product performance.
Bubble Generation: Moisture reacts with the isocyanate component to generate carbon dioxide gas, forming bubbles, affecting the appearance and performance of the product.
The chemical industry has a huge demand for molecular sieves, activated alumina, alumina ceramic balls, tower packings, etc. Each sub-segment will select designated adsorption or separation products for purification and refining according to different separation applications, such as chemical gas drying and purification, petroleum refining and separation, catalyst protection and carrier, fine chemicals and pharmaceuticals, chemical liquid drying and separation.

HOW IT WORKS
The physical adsorption characteristics of zeolite molecular sieves can selectively adsorb according to the size of molecular diameter. Its internal pores have strong polarity and can adsorb polar molecules and unsaturated molecules.
In the petroleum industry, the main role of molecular sieves is drying and H2S and CO2 desorption.
Thereby helping to obtain products with lower impurity content, reduce acid consumption, prevent corrosion of downstream equipment.
Molecular sieve zeolite has uniform pore size and large specific surface area, and can selectively adsorb different gas molecules according to their size, polarity and other characteristics. In the air separation industry, molecular sieves have strong adsorption for water, and can also selectively adsorb carbon dioxide in the air to prevent it from solidifying at low temperatures and clogging equipment and pipelines. At the same time,they can be used to separate gases in PSA and VPSA devices, achieving efficient separation of oxygen and nitrogen to obtain high-purity oxygen and nitrogen.
Xintao molecular sieve zeolite is used in the pharmaceutical industry as a molecular sieve adsorbent that can selectively adsorb impurities such as H2O, CO2, and organic matter in the pharmaceutical production environment, ensuring the dryness and purity of the pharmaceutical production and storage environment and extracting high-purity oxygen.
Xintao activated molecular sieve powder provides a solution for improving the effect of polyurethane adhesive. As a white powdered physical adsorbent, Xintao molecular sieve powder can effectively adsorb water molecules, carbon dioxide molecules, and hydrogen sulfide molecules in polyurethane components, and it is not easy to release at room temperature and pressure, thereby improving the effect of polyurethane adhesive in a long term.
Molecular sieves are a type of inorganic non-metallic porous crystalline material with a large specific surface area, regular pore structure and adjustable functional elements. They can effectively separate and selectively activate molecules with different diameters and different polarities.
Electronic products, semiconductors, and electronic components are widely used in computers, mobile phones, and automotive components in modern times. Water corrosion of electronic products will lead to product scrapping and difficulty in replacement. Xintao provides dehydration solutions that can make the electronic manufacturing production process and storage highly dry, ensuring the storage and application of electronic products.
Molecular sieves and activated alumina are usually used in production equipment and application equipment in the petroleum, chemical, pharmaceutical, and electronic industries, such as oxygen generators, nitrogen generators, adsorption dryers, etc.

Hydrogen Production
Using the selective adsorption function of molecular sieves and pressure swing adsorption equipment, hydrogen molecules in impurity raw gas can be separated and hydrogen can be recovered through the equipment, thereby realizing the sustainable use of hydrogen.
Biofuels
Since biogas contains a lot of water when it is produced from anaerobic fermentation equipment, in order to use it safely in the process, Xintao 4A molecular sieves cab be used to achieve high-precision drying and dehydration of biogas through physical adsorption.
Hydropower Equipment Maintenance
In the maintenance scenario of hydropower equipment, if the equipment parts are exposed to too much water, they may rust and corrode, so Xintao activated alumina is needed to dry the equipment environment.
