dow paper 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 waterand other additives. however, except for strong oxidizingagents.

2) peo to join a stable suspension that can help a variety ofsubstances dispersed in white water, so as to achieve ferreted outevenly and thin paper.

3) peo can be used to retain the softness of the pulp, create asoft 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 e: 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 roughly1:30 to 2:00 maximum viscosity occurs, with the stirring time afterthe viscosity stable phase, but because of the role of shearstress, viscosity decreased, but does not affect use, we recommenddissolution time in 2 hours -3 hours.

4. dissolved concentrations

peo polymer products are water-soluble products in use, if thesolution concentration is too high, there will be dissolved toolong, so affecting the normal production, we recommend the generaldissolution of the concentration of 0.05% -0.1%.

四, the dissolving tank

preferably stainless steel, plastic, frp and wood. rust willcause the rapid degradation of peo product, so should be usedcautiously. dissolving tank volume rate of consumption decisionsbased on peo.

stir

peo in the case of rapid mixing will degrade, so dispersedparticles, the high-speed mixing should be avoided. recommendedmulti-mixing, such as mixing 2 to 4 layers (as shown). in the caseof low speed, multi-layer mixing can achieve better dispersion.

feeding

the of pre-dispersed peo to determine the circumstancesof its dissolution, so the added method is essential. peo particlesshould be as much as possible so that uniformly dispersed in theliquid surface, feeding and tilting feed plate screen is very goodway. do not use materials directly to the peo shovel to dumpdirectly into the dissolving tank, this will cause a lot oflumps.

dilution

added directly to the stock solution, difficult to obtain gooddispersion. generally need to be diluted to 50-100ppm liquid plusnetwork before the box. to spread good dispersing agent to obtain agood dispersion.

五. use

ucarfloc the use of grades with use, the production of paper andpapermaking type of speed change, roughly the recommended amount asfollows:

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 weightof easily degradable, we use the bucket, filled with nitrogen, sothat to improve product stability. 63.5kg/10kg / box
