Why choose us?

Diverse Tower and Internals Supply

We provide a wide range of towers and internals in materials like special alloys, ceramics, graphite, plastic, and stainless steel. Liquid distributors (orifice, trough, ladder, spray nozzle types) and gas distributor spargers are designed for uniform distribution, considering scaling/foaming factors. Packing supports, bed limiters, and mist eliminators (mesh/chevron types) are offered to enhance purity and prevent equipment damage.

Comprehensive Chemical Technology Support

With an expert team, we offer full-cycle technical support and consulting for R&D, production, process optimization, supply chain management, and environmental compliance. Services include process optimization to boost efficiency, sustainability solutions for regulatory compliance, safety risk management, IP protection strategies, and supply chain integration to reduce costs.

High-Quality Industrial Equipment Provision

Specializing in chemical industry equipment, we offer top-grade materials resistant to corrosive/abrasive chemicals (solvents, acids, oils, etc.). Product lines include diverse pumps (barrel, pneumatic diaphragm, centrifugal) and customized skid-mounted systems for single-point connection. All equipment meets API standards, with pumps complying with ANSI for guaranteed reliability.

While the company’s formaldehyde expertise is well-established, specific phenol formaldehyde (PF) resin solutions are available through customized consultations. The company can assist in optimizing PF resin synthesis, including novolac (acid-catalyzed, resol (base-catalyzed) types, with phenol:formaldehyde ratios ranging from 1:0.8 to 1:1.5. Process parameters such as reaction temperature (80 - 100°C), pH control (1 - 4 for novolac, 8 - 12 for resol), and condensation time (2 - 6 hours) are optimized to achieve desired resin properties (viscosity 500 - 5000 cP, gel time 30 - 120 seconds). PF resin applications support includes formulation development for plywood adhesives (bond strength > 1.5 MPa), foundry cores (thermal stability > 200°C), and friction materials (heat resistance > 300°C). Environmental solutions for PF resin production include waste water treatment (phenol removal to < 10 ppm) and formaldehyde emission control (scrubbing systems with > 95% removal efficiency).
