Sumitomo paper dedicated dispersant PEO
一. Characters
Ingredients: PEO
Appearance: white to light yellow powder
pH value: 8 ~ 10 (0.5% @ 25 ℃)
Volatile matter: "1%
true density: 1.15 ~ 1.26g/cm3
apparent density: 0.4 ~ 0.6 g/cm3
二. Characteristics
1) PEO non-ionic polymer, is almost free from the impact of water and other additives. However, except for strong oxidizing agents.
2) PEO to join a stable suspension that can help a variety of substances dispersed in white water, so as to achieve ferreted out evenly and thin paper.
3) PEO can be used to retain the softness of the pulp, create a soft copy of the paper.
4) Use the product with excellent stripping properties of paper, it is easy to disengage from the Yankee cylinder.
5) does not tend to dust, it is easy to operate.
三. Solubility
A solution viscosity
Test equipment: Brookfield viscosity
meterConcentration: 0.1%, 0.3%, 0.5%
Speed: 12 rpm
Temperature: 25 ℃
Rotor: 0.1% 0.2% 1 # 2 # rotor rotor
2 dissolution rate
Solution conditions are as follows
Concentration: 0.5%
Mixing: 60rpm
Determination: Brandt viscometer (rotor # 2, 12rpm, 1 minute, 25 ℃)
3. Lysis time
Viscosity-time curves under the table, PEO dissolved in roughly 1:30 to 2:00 maximum viscosity occurs, with the stirring time after the viscosity stable phase, but because of the role of shear stress, viscosity decreased, but does not affect use, we recommend dissolution time in 2 hours -3 hours.
4. Dissolved concentrations
PEO polymer products are water-soluble products in use, if the solution concentration is too high, there will be dissolved too long, so affecting the normal production, we recommend the general dissolution of the concentration of 0.05% -0.1%.
四, the dissolving tank
Preferably stainless steel, plastic, FRP and wood. Rust will cause the rapid degradation of PEO product, so should be used cautiously. Dissolving tank volume rate of consumption decisions based on PEO.
Stir
PEO in the case of rapid mixing will degrade, so dispersed particles, the high-speed mixing should be avoided. Recommended multi-mixing, such as mixing 2 to 4 layers (as shown). In the case of low speed, multi-layer mixing can achieve better dispersion.
Feeding
The quality of pre-dispersed PEO to determine the circumstances of its dissolution, so the added method is essential. PEO particles should be as much as possible so that uniformly dispersed in the liquid surface, feeding and tilting feed plate screen is very good way. Do not use materials directly to the PEO shovel to dump directly into the dissolving tank, this will cause a lot of lumps.
Dilution
Added directly to the stock solution, difficult to obtain good dispersion. Generally need to be diluted to 50-100ppm liquid plus network before the box. To spread good dispersing agent to obtain a good dispersion.
五. Use
UCARFLOC the use of grades with use, the production of paper and papermaking type of speed change, roughly the recommended amount as follows:
PEO type papermaking use (kg / T)
Napkins 0.5-0.8
Toilet paper 0.8-1
Toilet paper 0.2-0.5
六. Packing
PEO products in the role of strong oxidant, the molecular weight of easily degradable, we use the bucket, filled with nitrogen, so that to improve product stability. 10KG / box
