Product Introduction

 

It primarily absorbs water, CH4, ethanol,SO2H2SCarbon dioxide, ethylene, propylene, do not adsorb any molecules with a diameter greater than 4A (including)CH3Our water selection adsorption properties exceed those of any other molecule. It is one of the most widely used molecular sieve types in the industry. It is extensively applied in drying gases and liquids, and can also be used for the refinement and purification of certain gases or liquids, such as the production of argon.

Chemical Formula: Na₂O·Al₂O₃.2SiO₂.9/2H2O Silica-to-alumina ratio: SiO/Al₂O₃ ≈ 2

Effective Aperture: Approximately 4A

Product Features

Excellent water absorption capabilities

Absorbency is a crucial performance indicator for refrigerant desiccants. Exceptional absorbency not only ensures the safety and reliability of the refrigeration system but also significantly extends the lifespan of the dry filter.

High Adsorption Acid Content
Dalian Haixin Chemical Refrigerant Desiccant, utilizing the technological process developed by the Dalian Haixin Chemical Research and Development Center, has been proven through experiments to have a 22% higher acid removal capability compared to similar products. Moreover, it does not undergo a chemical reaction with the refrigerant during the acid removal process, ensuring no impact on the refrigerant's chemical stability.

Low dew point and low wear rate
If the dew point of the refrigerant desiccant is not extremely low, it's prone to condensation at low temperatures, significantly affecting the refrigeration system; a high wear rate can shorten the desiccant's lifespan and leave residue. By utilizing Dalian Haixin Chemical's independently developed new process, the dew point of the refrigerant desiccant is much lower than that of similar products on the market, with a low wear rate, and strong protective capabilities for the refrigeration system.

High compatibility
Dalian Haixin Chemical Refrigerant Desiccant is widely applicable to various types of refrigerants, offering superior compatibility compared to other products that are designed for single types of refrigerants.

 

Application Fields

01. Used for drying saturated hydrocarbon materials and capable of adsorptionCH4Ethanol,H2SThere is no Chinese content provided for translation.

02. Water accumulation in the automotive braking air circuit can cause rusting of metal components, cracking of rubber sealing parts, degradation of lubricating oils, and pipeline blockages, severely affecting driving safety. Utilizing the XH-5 molecular sieve as a desiccant, it can absorb moisture from the system and exhaust it into the atmosphere, ensuring long-term and effective moisture absorption from compressed air to guarantee safety.

03. Used for the separation and purification of gas and liquid components, such as the production of pure, anhydrous ethanol for argon. In the light industry, it is applied in papermaking, synthetic rubber, plastics, resins, paint fillers, and quality colors. In the development of energy and the electronics industry, it serves as an adsorption separator and desiccant.

If the water content in "tian ran qi" fails to meet the required standards, it can lead to hydrate formation, blocking pipelines, gas cylinder nozzles, inflation nozzles, etc.: the precipitated free water will freeze and freeze the equipment and pipelines of the system; pressure vessels may experience SSC, and the presence of free water can cause severe internal wall corrosion and other hazards. The HX-4A can ensuretian ran qiThe humidity reaches -70°C at atmospheric dew point, avoidingtian ran qiThe dangers of water overabundance.

Packaging

25KG cardboard box, lined with PP sealed bags

235L Sealed Steel Drum (Net Weight: 150 kg)

Insulated Sealable Polypropylene Container Bags (600kg or 750kg)

Storage:Store in a well-ventilated, dry storage facility. Prevent moisture and rain during transportation. Avoid adsorption of water and organic matter before use; otherwise, regeneration is required.
