Crystal fine powder

　　Performance Curve:

　

1. Low viscosity: use penetration to obtain a suitable sizing rate

2. The viscosity is stable with temperature and concentration: keep the slurry performance consistent

Features of the new slurry:

Excellent adhesion

It has super adhesion to polyester fiber and glass fiber, and its excellent film-forming properties play an important role in protecting warp yarns, saving 20%-30% of the cost compared to acrylic. If it is used as a surface coating to increase the surface hardness, it can meet different stiffness requirements.

Drying performance

Easy to dry, 15%-20% faster than acrylic.

Excellent penetration

Due to the low viscosity of the prepared slurry, the penetration is very good, and it can be sizing at room temperature, thus saving energy.

Moderate hygroscopicity

No re-viscosity, and the moisture absorption of the serous film is less than 0.5% when the relative humidity is 70%.

High molecular weight

The sizing film is flexible and has excellent adhesion to polyester fibers, and the sizing film is smooth, complete and wear-resistant.

Good environmental performance

It can be hydrolyzed, acid-base degradation and photolysis. Not only the degradation performance is good, but also the dosage is small, and the impact on the environment is small. BOD/COD>0.3 detected by Sichuan Environmental Testing Center.

  cut costs

Due to the super strong adhesion and excellent film-forming properties of HZ, the dosage is relatively reduced, which effectively reduces the production cost by 40%-50%.

Packaging and storage:

1. Kraft paper plastic film composite packaging, net weight 25kg per bag.

2. Store in a cool and ventilated place.

3. Strictly prevent moisture, exposure, high temperature, so as not to agglomerate.

  Instructions for use:

1. Sizing

Compared with the concentration of acrylic acid, the concentration can be appropriately reduced.

(1) At normal temperature, put an appropriate amount of water in the mixing barrel according to the concentration required by the user, and start stirring and input the raw materials at one time.

(2) Stir well, heat up to boiling, and then simmer at a constant temperature for more than 60 minutes until the slurry is completely dissolved.

(3) Cool down to 600 C, then add appropriate amount of additives and stir evenly, then filter with a filter screen of 200 mesh or more, put it into a clean storage bucket, and cover it for storage.

2. Dissolve

(1) The sizing temperature is controlled at normal temperature.

(2) Because the slurry is easy to dry, the drying temperature of sizing is slightly lower than that of acrylic acid.

(3) Due to the strong adhesion of the new type of paste, the sizing rate can be appropriately reduced compared to the original (acrylic paste).

3. Sizing

4. Desizing method

Add an appropriate amount of sodium hydroxide with pure water, then add an appropriate amount of dispersant and heat it to above 95°C.

★Note: (1) When the temperature is more than 950C when boiling the pulp, it must be stirred and boiled for more than 60 minutes to completely dissolve the product, otherwise the viscosity of the slurry will easily increase several times; it should not be stored in a high temperature pot for a long time, otherwise it will easily make the slurry damage, resulting in poor penetration of the slurry, and causing the pulp filament to stick and break.

(2) After adding the auxiliary materials, it must be filtered with a 200-mesh filter screen. It is necessary to add multiple screens on the pulper, otherwise some impurities will be brought into the pulp wire, and the pulp wire will be broken when it is paralleled.
