Key Materials Used in Sandblasting Hoses
Today, the market offers various sandblast hose materials such as rubber, silicone, and polyurethane, each suited for distinct environments and requirements.
- Rubber sandblasting hoses are known for their excellent wear resistance and anti-aging properties, making them suitable for diverse sandblasting scenarios.
- Silicone sandblasting hoses stand out for their high-temperature resistance and chemical stability, making them ideal for extreme conditions involving high pressure and heat.
- Polyurethane sandblasting hoses excel in oil resistance and wear resistance, tailored for oily particle environments in sandblasting operations.
The Functionality of a Sandblasting Hose
The primary function of a shot blast hose is to transport sand particles efficiently. During the sandblasting process, these particles must be conveyed to the sandblasting gun via the hose, enabling the particles to be sprayed onto the intended surfaces. This means the hose’s transport capability directly impacts the overall sandblasting effectiveness. Additionally, a quality sandblasting hose ensures excellent sealing performance to prevent sand leakage, thereby maintaining a clean environment. Lastly, it must withstand high pressure, crucial for maintaining process stability.
Operational Mechanics of Sandblasting Hoses
When compressed air flows through a sandblasting hose into the sandblasting gun, it accelerates the sand particles toward the targeted surface, facilitating its treatment. During this entire operation, the hose must endure the combined stress of sand particles and high-pressure air. Therefore, the quality of the hose is pivotal to both the efficiency and safety of sandblasting.
Blast Hose Buying Guide
Today we’re going to walk you through the process of manufacturing blast hoses.
It all begins here at the Banbury mixer, which blends the 13 essential ingredients forming the rubber compound used in blast hoses. Here, you will receive efficient and thoughtful service from HESPER.
We at BlastOne prioritize sourcing the highest quality materials from the best vendors, distinguishing our blast hoses from competitors. The output from the Banbury is rubber sheets, which require batching. Each batch undergoes rigorous testing, including briometer evaluations for rubber properties and abrasion resistance tests, ensuring our hoses meet a stringent abrasion loss standard of no more than 50 cubic millimeters.
Following the Banbury, the rubber sheets are calendared to achieve uniformity, aided by zinc stearate dusting to prevent sticking. This step is crucial for maintaining high-quality material consistency. Next, the Textile Calendar embeds reinforced textile fabric within the rubber, providing necessary pressure ratings to the hoses.
Mandrel manufacturing is the backbone of blast hose production. A mandrel dictates the hose’s inner diameter, around which rubber layers, including a static-dissipating copper wire and reinforced textile fabric, are methodically applied. The assembled hose then undergoes vulcanization, where it’s cured at 150 degrees Celsius (302°F) and 60 PSI for 70 minutes, ensuring all components meld homogeneously. Post-vulcanization, the hoses are cooled, removed from the mandrel, and inspected.
