Initial Waterproof Performance is Poor
cause:
First, processing cloth: refined or dyeing cloth is not fully cleaned.
Second, the problem of working liquid: The concentration of use is improper or the concentration in processing changes, or the work solution is affected by mechanical stirring, temperature, and spelling agents, and stability is affected. There is another improper order of work liquid.
Third, the reasons for processing conditions: The choice of waterproofing agent is not proper, or the drying and baking conditions are insufficient, and they are not uniform.
solution:
1. Before waterproof processing, the processing cloth should be fully washed;
2. Choose a waterproofing agent suitable for processing fiber, and continue to supplement the new prepared work solution as much as possible during processing;
3. Strengthen the temperature management of the processing cloth to avoid the hot cloth after drying directly into the people's studio;
4. Understand the compatibility of the spelling agent, and prepare the work solution in the order of allocation;
5. The prepared working liquid needs to be used within 24h;
6. Dry and roasting temperature should be uniform, and the roasting temperature should not be too low, generally above 140 °C.
The Reasons and Countermeasures of the Sticky Roller During Waterproof and Oil -Proof
1. Differences of product stability: Under the same process conditions, the probability of different waterproof oil -proof rollers is very different. Adding filling doses to increase the waterproof oil -proof agent with solid mass scores will cause product stability to decrease.
2. Equipment: When the rough rolls on the surface are soaked with waterproof oil -proof, the surface of the roll is easily stained with precipitated objects, and the probability of a sticky roller generated by the steam baking cylinder will increase significantly.
3. Residual aids on the fabric surface: The pre -poison fabric is not cleaned, and the residue is more than more pineral surface active agent. White polyester cloth will appear more white spots during waterproof and oil -proof treatment, and the sticky roller phenomenon is serious: the same specifications of the dye cloth are better, because after the dye cloth is dyed at high temperature, the cloth residues are mostly decomposed at high temperature. The face is cleaner.
The solution is to strengthen the cleaning of the cloth surface.
4. Processing environment: The sticky roller phenomenon is seasonal, and it is concentrated in summer and autumn. During waterproof oil and oil -proof processing, the probability of the temperature of the temperature exceeds 35 ° C is significantly increased. There is also the oversold of groundwater organic matter that can easily cause stickiness.
The solution is to use tap water and clean up the dirt on the rolling.
Poor Performance of Waterproofing Agent
Cause:
The processing fabric is not sufficient; the processing conditions, especially the baking conditions, are not in line with.
Solution:
After dyeing directly or active dyes, the cloth with fixed color should be washed. Choose the right cross -linked agent or resin and use it during the shelf life.
Waterproof strip spots
Cause:
The processing fabric is not sufficient; the processing conditions, especially the baking conditions, are not in line with.
Solution:
After dyeing directly or active dyes, the cloth with fixed color should be washed. Choose the right cross -linked agent or resin and use it during the shelf life.
Waterproof Stain
Cause:
Poor stability of the working liquid: After stirring at high speed, check whether there is a residue on the surface and the roller of the working liquid. You can also touch it with your hands.
Solution:
Note that the temperature of the working solution does not exceed 35 °C; when the malignant bubble is found, the stabilizer (isopenol) is added.
The Color Light Has Changed a Lot
Cause:
The main cause of color and light changes is caused by the deepening effect of fluorine resin. This is also a phenomenon that cannot be completely avoided during waterproof processing.
Solution:
Solving color light changes can be confirmed through the preparation test, and then coloring is performed; it is supplemented as timely and timely in time.
