Oxidized polyethylene wax has various applications in the industrial field, mainly encompassing the following aspects: Coating and ink industry: Oxidized polyethylene wax is an important additive in coatings and inks. It provides good lubricity, helps to disperse pigments and dyes evenly, increases the gloss of coatings and inks, and improves their wear resistance and scratch resistance. It can also regulate the fluidity and viscosity of paints and inks, enhancing their printing performance. Plastics industry: In plastic processing, oxidized polyethylene wax is used as an internal and external lubricant, which can reduce the friction between plastic particles and equipment, improve the fluidity and processing performance of plastics, lower the processing temperature, and reduce energy consumption. At the same time, it can also enhance the surface glossiness and wear resistance of plastic products, and improve the molding and demolding performance of plastics.

1. Host (Main Unit) – Contains the heating unit, temperature sensor, temperature control circuit, and power unit. It filters and heats air to a set temperature, then delivers warm air through the air supply pipe to the heating blanket. 2. Display Screen – Shows the set temperature (25–45°C), current runtime, cumulative power‑on time (0–10,000h cycle), and countdown timer. The screen enters rest mode after 10 minutes of inactivity but wakes with any key press or alarm. 3. Control Knobs / Buttons – Include four shortcut keys for room temperature / 25°C / 32°C / 38°C / 43°C, plus continuous adjustment in 0.1°C steps (fast‑forward capable). Wind speed is adjustable across 9 levels (low, medium, high three domains). 4. Air Filtration System – Epoxy‑sterilized system with HDPE‑type G4 primary filter + H13/H14 high‑efficiency filters, achieving filtration efficiency for particles ≤0.2μm. H13/H14 filter replacement is required every 12 months or 2000 hours.

pipeline pump is a centrifugal pump directly installed on the pipeline, with its inlet and outlet aligned in the same straight line. It is used in series like a valve and primarily serves to boost and transport liquids. 1.Pipeline pumps are single-suction single-stage or multi-stage centrifugal pumps with vertical or horizontal configurations. They feature identical inlet and outlet ports aligned on the same central axis, allowing direct flange connection and installation in the pipeline without requiring additional suction piping. 2. Relationship with Centrifugal Pumps: The pipeline pump is a special type of centrifugal pump, operating on the same principle (motor drives the impeller to rotate and generate centrifugal force for pressurization). The difference lies in its more compact structure, coaxial inlet and outlet design that eliminates the need for a suction bend, and simpler pipeline layout. Core working principle: The electric motor drives the pump shaft and impeller to rotate at high speed. Liquid is drawn into the pump body and flows axially along the impeller, where centrifugal force pushes the liquid toward the outlet, increasing pressure to overcome pipeline resistance, enabling long-distance or elevated transport Type and application Classification by conveyed medium: ISG-type water pump: Suitable for conveying domestic water and circulating water at normal temperatures, with a medium temperature range of -20°C to 80°C. Commonly used in central air conditioning systems and factory circulating water systems. Hot water pump (IRG type): Used for conveying boiler hot water and underfloor heating circulation water, with a medium temperature range of 80°C to 140°C. The pump body is equipped with heat dissipation fins, and the mechanical seal is resistant to high temperatures. Oil Pump (YG Type): Suitable for transporting gasoline, kerosene, and diesel with a medium temperature range of -20°C to 120°C. Equipped with explosion-proof motors, it is used in the petroleum industry and oil depot pressurization. Chemical Pump (IHG Type): 316L stainless steel pump body, suitable for conveying mild acid and alkali chemical media, corrosion-resistant. Classified by installation form: Vertical pipeline pump: The motor is vertically upward and occupies a small area. It is installed on a horizontal pipeline and needs to be removed during maintenance. Horizontal pipeline pump: The motor is arranged horizontally for easy maintenance, and the mechanical seal is easy to replace in the later stage. It occupies a large area and is preferred for large power applications Typical application scenarios: High rise building pressurized water supply, central air conditioning cooling/chilled water circulation, boiler hot water circulation, fire pressurization, industrial process liquid transportation, hotel and shopping mall tap water pressurization.
