Product Overview & Core Features

The Diatomaceous Earth Absorbent Board is made from diatomite, a natural mineral with a unique microporous structure. When indoor humidity rises, its ultra-fine pores automatically absorb moisture from the air.

Through dedicated research on diatomite functions, we are committed to creating “beautiful and comfortable” products for consumers.

 Easy to Clean

1. Frequent use may cause dirt to adhere and block the surface, reducing water absorption. In this case, sand the surface with 300-grit sandpaper to remove dirt and restore absorbency. Wipe off dust with a dry cloth.
2. Regularly dry in a well-ventilated area: once a week in summer, twice a week in winter. Drying prevents odors and mold; cleaning frequency depends on the usage environment.

Safe Usage Guidelines

1. Do not soak in water for extended periods to avoid crystal aging and damage.
2. Do not use on tiles or slippery surfaces; use with a non-slip mat to prevent slipping.
3. After cleaning, air-dry the mat in an upright position.
4. Avoid applying excessive pressure, such as stepping on it when 架空成三角形 (supported in a triangular shape), which may cause cracks.
5. Do not clean with detergents, as surfactants can block pores.
6. Do not expose to direct sunlight.

Natural Texture & Color Variations

The following may occur during manufacturing but do not affect quality:

  1. Small spots on the mat
  2. Slight bumps on the sides
  3. Minor notches on the surface or edges
  4. Fine powder on the surface (wipe with a dry cloth)
  5. Gradual fading of the mat’s natural odor during use

Application Scenarios

Shoe insoles, cup coasters, tableware mats, foot pads, umbrella mats, with custom services available.

Key Product Features

100% Natural Diatomite Composition

Diatomite is formed by the sedimentation of plankton in oceans and lakes over approximately 10 million years. It is free of heavy metals, resistant to mildew and bacteria, highly absorbent, and can purify air and regulate humidity.

Superior Water Absorption Capability

Diatomite has water absorption 5,000 times stronger than activated carbon. Its dense porous structure absorbs moisture while releasing vapor for rapid drying, keeping the surface fresh during use.

Anti-Mold, Anti-Mite Performance

Compared to traditional bath mats made of ordinary fibers, diatomite’s weak alkaline property and porous molecular sieve structure trap bacteria and absorb their moisture, making it difficult for bacteria to survive or reproduce. Families can share the same foot pad without worrying about cross-infection from athlete’s foot.

Air Purification & Odor Removal

The countless tiny pores on the diatomite surface absorb and decompose formaldehyde, benzene, and radioactive substances, converting them into harmless materials—purifying the air for a healthy, cozy home.

Why Choose Us

Comparison with Similar Products from Peers

Cost-Effectiveness

With full certification for export to European markets, JOINBLING fiber cement boards deliver excellent cost-performance compared to similar brands. They meet international safety and durability standards while providing a reliable, affordable solution tailored to modern construction needs.

Superior Quality

Many counterfeit boards fail to meet basic flexural strength standards. In contrast, JOINBLING boards pass strict curtain wall performance tests, including air tightness, water resistance, wind pressure, and planar deformation. This ensures consistent strength, high density, and minimal warping or structural instability.

High Manufacturing Standards

Compared to low-grade products from asbestos-based or unregulated factories, JOINBLING boards offer superior quality—featuring uniform thickness, minimal surface defects, consistent texture, and stable color performance. These qualities ensure aesthetic consistency and long-term reliability in professional applications.

Generation process

Raw material preparation

We carefully select and proportion high-quality raw materials such as plant fibers, cement, silica, and additives. This step ensures the strength of the base layer of the fiber cement board, laying a solid foundation for its durability, dimensional stability, and resistance to harsh environmental conditions.

Stirring processing

All raw materials are mixed into a uniform slurry using an advanced automated system. The precise mixing process ensures uniform fiber distribution and stable composition, which is essential to ensure the consistent performance of each fiber cement board.

Pressure forming

The fully mixed slurry is pressed under high pressure to compact the material into a dense and hard board. The pressing process strengthens the structure of the fiber cement board and improves its ability to resist cracking, warping, and long-term wear and tear due to moisture or wind and sun.

Board Maintenance

After pressing, the raw board is moved into a controlled curing environment with strict temperature and humidity settings. This board curing process promotes cement hydration so that each board achieves the best mechanical properties and surface hardness.

Drying

Partially cured boards enter the drying room to remove excess moisture. Once dry, it is carefully unloaded and prepared for subsequent processing. This critical step prevents the finished fiber cement board from deforming, mold or internal stress.

Cutting

The dried boards are cut using automated precision cutting machines to form standard or custom sizes. Precise dimensions and smooth edges ensure installation efficiency and meet architectural design standards for fiber cement board applications.

Quality Inspection

Each fiber cement board undergoes a strict quality control process, including size, thickness, strength, and appearance inspections. Only boards that meet international standards such as CE or AS/NZS are approved for distribution.

Product storage

Finished boards are stacked and stored in moisture-proof, organized storage areas. Proper labeling, protective packaging, and inventory control ensure that fiber cement boards maintain quality during transportation and can be delivered quickly around the world.

FAQs – About Diatomaceous Earth Board

1. Is diatomite safe for homes with children and pets?

100% natural, chemical-free, and free of heavy metals or irritants. Safe for children and pets—no harm if accidentally touched or licked, ideal for Mother and Baby households (baby and mother families).

Absorbs water instantly and restores a dry surface within 3-5 seconds. The microporous structure ensures quick water penetration and continuous non-slip performance for safer bathroom use.

Diatomite’s natural weak alkalinity and porous structure double as antibacterial agents, with moisture rapidly evaporating to prevent mold. Maintains cleanliness even in southern plum rains or water-prone areas.

The porous molecular sieve “locks” bacteria and absorbs their moisture, making it impossible for fungi like athlete’s foot to survive—reducing cross-infection risk by 99% compared to traditional fiber pads.

Surface pores adsorb and decompose harmful gases like formaldehyde, with continuous purification. Unlike activated carbon, diatomite remains effective throughout its lifespan without needing replacement.

Rinse with water monthly and air dry to restore performance; gently sand stubborn stains with fine sandpaper. Proper maintenance ensures a lifespan of over 5 years.
