**Secondary PU & Alloy Belt Cleaner (DB-PPA)**
The DB-PPA Secondary PU & Alloy Belt Cleaner is a high-performance solution designed for secondary cleaning applications on conveyor belts. It can be installed at any secondary cleaning position, typically around 100mm from where the belt exits the head pulley. This ensures effective removal of residual material, reducing carryback and improving overall system efficiency.
The cleaner features a polyurethane (PU) blade equipped with a Tungsten Carbide tip, offering exceptional durability and resistance to wear, even in harsh environments. The unique spring tension design allows for consistent contact pressure, ensuring optimal cleaning performance under varying conditions.
This belt cleaner is ideal for a wide range of industrial applications, including those involving wet, sticky, or difficult-to-remove materials. It is compatible with both mechanical and vulcanized joint belts and supports belt widths ranging from 500mm to 2000mm.
**Key Features:**
- Durable PU blade with Tungsten Carbide tip
- Adjustable spring tension for optimal performance
- Suitable for wet, sticky, and challenging carryback conditions
- Compatible with mechanical and vulcanized joints
- Easy installation and maintenance
**Applications:**
1. Belt Width: 500 ~ 2000 mm
2. Suitable for both mechanical and vulcanized joint belts
3. Ideal for tough applications with wet or sticky carryback
4. Designed for long-lasting performance in demanding environments

Whether you're operating in a mining, manufacturing, or logistics environment, the DB-PPA series offers reliable, efficient, and cost-effective belt cleaning solutions. Its robust construction and versatile design make it an essential component for maintaining clean, efficient, and safe conveyor systems.
PHA fiber is a biocompatible and degradable whole biological polymer produced by various microorganisms (such as soil bacteria, cyanobacteria, transgenic plants, etc.). This fiber has excellent biocompatibility, optical activity, piezoelectricity, moisture resistance, low permeability and other good properties, under normal circumstances stable nature, but in the soil, lakes, oceans and other environments are easy to biodegrade, so the use of PHA fiber products buried in the soil or placed under the water can quickly degrade, thereby reducing environmental pollution. PHA fiber products can be used for medical materials, health materials and other aspects. In addition, PHA fiber has complete biodegradability, excellent biocompatibility, good physical properties and thermal processing properties, but also has a natural antiviral and antibacterial effect, so it is an advanced material for the production of high-end clothing, underwear and so on.
Recently, scientists at The National Renewable Energy Laboratory (NERL) and Colorado State University, in collaboration with The North Face, have developed a range of PHAs with different properties, some of which are similar to conventional polyester, but they are bio-based, biodegradable, and easier to recycle. The collaboration brings sustainable materials to the outdoor apparel industry, with plans to produce several pounds of PHA fiber over the next 12 months and to test and evaluate its use in The North Face product line.
In addition, the study of PHA fibers also involves blending with other materials to improve their properties. For example, blending silk with 5wt% titanium dioxide can overcome the adhesion problem of pure PHA and improve the fiber strength; When it was blended with polyethylene terephthalate (PET), the spinnability was good when the spinning temperature was 285℃ and the PHA content was 1.5-2.5wt %, and the maximum drawing ratio increased with the increase of PHA content. The toughness and thermal stability of PHA fiber can be greatly improved by adding PHA-B-PCL block copolymer.
In summary, PHA fiber, as an all-bio-polymer material, not only has good environmental friendliness and biocompatibility, but also has extensive application potential and research value.
