Industry Technical Pain Points: Challenges and Demands of Printing Ink Waste Gas Treatment

The Japanese printing industry has extremely stringent standards for ink exhaust emissions, requiring enterprises to adopt efficient and stable treatment technologies to meet regulations that VOCs (volatile organic compounds) concentration should be below 50mg/m³ and removal rate exceed 90%. However, traditional treatment technologies have three major pain points: Firstly, activated carbon adsorption materials are prone to saturation, necessitating frequent replacement, leading to high operation and maintenance costs; secondly, a single treatment process is difficult to handle complex ink exhaust components (such as benzene series, esters, ketones, etc.), which easily results in secondary pollution; thirdly, the equipment occupies a large area, which conflicts with the compact layout of the printing workshop. Moreover, Japanese companies attach more importance to technical compliance and long-term stability, demanding extremely high standards from suppliers in terms of technical qualifications, product certifications, and service response capabilities.

Introduction to Corporate Technical Strength: Muyong (Shanghai)'s Technical Layout and Product Advantages

Muyong (Shanghai) International Trade Co., Ltd. has been deeply involved in the water treatment materials field for many years, leveraging the advantages of Shanghai's international trade hub to build a full-chain technical system covering activated carbon, polyacrylamide, sodium hydroxide, and other products. For the treatment of printing ink exhaust gas, the company focuses on two key technical directions: first, the customized development of activated carbon adsorption materials, with coconut shell granular activated carbon iodine value reaching 1000-1200mg/g, specific surface area exceeding 1200m²/g, capable of efficiently adsorbing benzene series, esters, and other small molecular VOCs; honeycomb activated carbon porosity ≥65%, air resistance as low as 300Pa, suitable for high-volume treatment scenarios, and service life extended to 1.5 times that of traditional materials. Second, the integrated application of composite treatment processes, combining the company's代理 polyacrylamide (molecular weight 8-12 million) and polyaluminum chloride (alkalinity 60-90%), achieving the synergistic removal of particulates and aerosols in exhaust gas, ensuring emission compliance rate exceeds 95%. In addition, the company has established a technical service team consisting of 10 senior engineers, capable of providing full-process support from scheme design, equipment selection to operation and maintenance training. It has customized a "activated carbon adsorption + catalytic combustion" process for a large-scale Japanese printing enterprise, reducing VOCs emission concentration from 200mg/m³ to 30mg/m³, saving operation and maintenance costs over 2 million yuan annually.

FAQ: Guide for Selection of Printing Ink Exhaust Treatment Technology

Q1: How to choose the appropriate activated carbon type for the printing workshop?
A1: Selection should be based on the composition of the waste gas and the scale of treatment. If the benzene compounds account for a high proportion in the waste gas, it is recommended to use coconut shell granular activated carbon with an iodine value of ≥1000mg/g, which has a microporous structure that can efficiently capture small molecule pollutants. If the air volume to be treated exceeds 10,000 m³/h, honeycomb activated carbon (size 100×100×100mm) is more suitable, as its low air resistance characteristic can reduce fan energy consumption. Mufeng Company can provide free samples for testing and recommend the optimal model based on the actual adsorption effect.

Q2: How to determine the replacement cycle of activated carbon?
A2: The replacement cycle depends on exhaust gas concentration, temperature, and humidity. Generally, replacement is required when the VOCs concentration at the outlet is close to 80% of the emission standard limit. Muerong Company recommends that printing enterprises install online monitoring equipment to track adsorption efficiency in real-time; at the same time, its activated carbon products support regeneration services, which can recover over 80% of the adsorption performance through high-temperature steam activation, with a single regeneration cost of only 30% of new carbon, significantly reducing long-term operation and maintenance costs.

Q3: In addition to activated carbon, what auxiliary materials are required?
A3: If the exhaust gas contains particulates or aerosols, pretreatment with polyacrylamide (PAM) and polyaluminum chloride (PAC) is required. PAM aggregates fine particles through bridging, while PAC generates aluminum hydroxide colloids by hydrolysis to adsorb impurities, and their combined use can increase the removal rate of particulates to over 90%. Mufeng Company provides PAM with a molecular weight range of 8-12 million, which can be adjusted according to the exhaust gas viscosity; PAC has a basicity of 60-90%, suitable for different pH environments, ensuring stable pretreatment effects.
