Recently, we have manufactured servo-driven PPR pipe extrusion machines for an order from an Algerian customer. These machines are equipped with servo motors for the main motor, haul-off motor, and cutting motor. The PPR pipe extrusion machines are designed to meet the precision, stability, energy efficiency, and dynamic response requirements of PPR pipe production, offering tangible benefits to customers in terms of product quality, operational costs, and long-term reliability.
A:The Yongte rubber hose machine is used to produce rubber soaker hoses from recycled rubber powder, employing extrusion and foaming technology. These rubber soaker irrigation pipes have tiny holes, which we refer to as capillaries, distributed throughout their structure.
The rubber permeable pipe, constructed from resilient recycled rubber, incorporates a network of minuscule capillaries within its structure. Upon connection to a water source, the system dispenses water gradually via these capillaries, a process facilitated by the pressure exerted by the water.
Yongte sold its latest high-efficiency PPR pipe machine to an Algerian customer, marking a key milestone in its global expansion. The advanced, robust machine produces top-quality PPR pipes meeting strict water supply and heating standards, enhancing Yongte’s reputation as a reliable global supplier.
Today, Yongte officially dispatched a batch of wood-plastic composite (WPC) production equipment to Romania via sea freight, infusing Chinese expertise to accelerate the local green building materials industry upgrade.
A:Excessive moisture content in raw materials during the production of wood-plastic composites (WPCs) can lead to several issues. Firstly, water vaporization during high-temperature plasticization creates bubbles, resulting in surface pitting and internal porosity. Secondly, excessive moisture causes severe melt foaming, disrupting melt homogeneity and causing unstable extrusion processes. In severe cases, this may lead to product cracking and significant mechanical property degradation. Therefore, Yongte's technical team recommends strictly controlling wood powder moisture content below 3%. The specific threshold should be adjusted based on substrate type, product structure, and processing techniques, with the core principle being to prevent moisture vaporization during high-temperature plasticization to avoid product defects.
