Say goodbye to blind addition! Advanced guide to efficient use of feel agents

Preparation before use

Understand product characteristics

Read the instructions: Read the instructions of the feel agent carefully to understand its chemical composition, scope of application, usage, safety precautions and other key information. Different types of feel agents have different compositions and performances. For example, silicone feel agents and amino silicone feel agents are different in performance and application. Understanding this information will help to use them correctly.

Consult the supplier: If you have any questions about the contents of the instructions, contact the feel agent supplier in time to obtain professional technical guidance. Suppliers usually have an in-depth understanding of the product and can provide targeted suggestions based on your specific needs.

Test compatibility

Small sample test: Before using the feel agent on a large scale, conduct a small sample test. Take a small amount of the material to be treated, add the feel agent according to the predetermined process, and observe the effect after treatment, including the degree of improvement in feel, appearance changes (such as color, gloss), etc. For example, in textile processing, first treat a small piece of fabric to check whether the feel meets expectations, and observe whether the fabric has discoloration, wrinkles and other problems.

Compatibility test with other additives: If other chemical additives, such as softeners, color fixatives, etc., are used in the production process, it is necessary to test the compatibility of the feel agent with these additives. Mix the feel agent with other additives in a certain proportion to observe whether adverse reactions such as precipitation, stratification, and gelation occur.

Prepare tools and equipment

Measuring tools: Use precise measuring tools, such as electronic balances, measuring cups, etc., to ensure that the amount of feel agent added is accurate. Too much or too little addition may affect the treatment effect and even damage the product.

Mixing equipment: According to the production scale and treatment process, prepare suitable mixing equipment, such as agitators, dispersers, etc., to ensure that the feel agent can be evenly dispersed in the treatment system.

Precautions during use

Control the amount of addition

Follow the recommended amount: Add strictly according to the instructions for the feel agent or the recommended amount provided by the supplier. Insufficient addition may not achieve the expected feel improvement effect, while excessive addition may cause problems such as greasy and sticky products, and even affect other properties of the product. For example, in the production of plastic film, adding too much feel agent may make the film surface too smooth, affecting the subsequent printing or laminating process.

Gradual adjustment: If the amount of feel agent needs to be adjusted, it should be done step by step, and the treatment effect should be observed after each adjustment to avoid too large a one-time adjustment.

Control process conditions

Temperature: Different feel agents have different requirements for the treatment temperature. Some feel agents need to be within a certain temperature range to achieve the best effect. For example, some silicone feel agents can better combine with materials and improve the feel at high temperatures. Therefore, the treatment temperature should be strictly controlled to ensure that it reacts within the appropriate temperature range.

Time: The treatment time will also affect the effect of the feel agent. If the treatment time is too short, the feel agent may not be able to fully penetrate or react, resulting in an unobvious improvement in the feel; if the treatment time is too long, it may cause energy waste and even affect the quality of the product. The appropriate treatment time should be determined according to the type of feel agent and the treatment process.

pH value: Some feel agents have requirements for the pH value of the treatment system. For example, some acidic or alkaline feel agents need to be stable and work under specific pH conditions. Therefore, the pH value of the treatment system should be adjusted to the appropriate range.

Ensure uniform dispersion

Pre-dispersion: For some feel agents that are difficult to dissolve in water or treatment systems, pre-dispersion treatment can be performed first. For example, the feel agent is mixed with an appropriate amount of solvent or emulsifier, and it is evenly dispersed by stirring, heating, etc. to form a stable emulsion or solution, and then added to the treatment system.

Fully stir: After adding the feel agent, the treatment system should be fully stirred so that the feel agent is evenly distributed on the surface or inside of the material. The stirring method can be selected according to the characteristics of the treatment system, such as mechanical stirring, air flow stirring, etc.

Post-use treatment

Equipment cleaning

Timely cleaning: After using the feel agent, the treatment equipment and tools should be cleaned in time to prevent the feel agent from remaining. The residual feel agent may clump or deteriorate on the inner wall of the equipment, affecting the effect of the next use, or even damaging the equipment. For example, in paint production, if the stirring equipment is not cleaned in time, the feel agent may dry and solidify on the inner wall of the equipment, increasing the difficulty of cleaning.

Choose a suitable cleaning agent: Choose a suitable cleaning agent according to the type of feel agent. For silicone feel agents, organic solvents such as ethanol and isopropanol can be used for cleaning; for water-based feel agents, they can be rinsed with clean water.

Waste liquid treatment

Environmental protection treatment: Waste liquid generated during use may contain feel agents and other chemicals and cannot be discharged at will. It should be properly handled in accordance with local environmental protection laws and regulations, such as entrusting qualified units to handle it, or performing pre-treatment such as neutralization and precipitation before discharging.

Effect evaluation and feedback

Effect evaluation: Evaluate the feel, appearance, performance and other aspects of the treated product to check whether it has achieved the expected goals. It can be evaluated by professional instrument detection or manual touch, observation and other methods.

Feedback and improvement: Based on the evaluation results, summarize the experience and lessons, and promptly feedback to the feel agent supplier or R&D department to improve the product or use process. For example, if the feel improvement effect is found to be unsatisfactory, it can be analyzed whether the type of feel agent is improperly selected, the amount of addition is inappropriate, or there is a problem with the process condition control, so as to take corresponding improvement measures.
