产品描述

AKD neutral sizing agent is an alkyl ketene dimer ( abbreviated AKD), a cationic surface active agent as raw materials, homogenizing the emulsion formed white emulsion , a suitable alkaline (pH value 7.5 ~ 8.5 ) under the conditions of reaction papermaking sizing agent . Widely used in various high-grade cultural paper , photographic paper, fruit bag paper, packaging paper and paperboard production of adhesive tapes and other facilities. Other featured products : Alkyl
ketene dimer (AKD wax), cationic reagent
(3-Chloro-2-hydroxypropyltrimethyl ammonium chloride/quat 188/CHPTAC), general
AKD emulsifier 25%, Quat 188 69%,Polymer emulsifier 40%, PolyDADMAC 40%,Wet
strenght agent 12.5%/25%, Styrene Acrylic Copolymer, Fixing agent 50%, Poly
Aluminium Chloride, Sodium Gluconate Oxidized starch,ect. 



1. Features 
1) . Significantly improved paper strength , toughness , whiteness and opacity. Improve the printability of paper . 
2) . Paper gives good optical properties and chemical stability , the paper long shelf life, easy to turn yellow . 
3) . High tolerance for calcium carbonate filler ( 10 ~ 30% ) , saving fiber raw materials , reduce slurry consumption . 
4) . Without aluminum sulphate , white water soluble solids greatly reduced, Whitewater lockable cycle , reduce environmental pollution , water conservation . 
5) . As the alkaline papermaking conditions , the device can be reduced corrosion, extend the mesh fabric , felt life.


6) . Small bubbles , no dirt, clean the wet end system to improve runnability. 


 


2. Technical Indicators 
1) . Appearance : white emulsion 
2) . Solid content : 10 ± 0.5%, 12 ± 0.5%, 15 ± 0.5%, 19 ± 1% 
3) . pH value: 3-4 
4) . Ionic: Cation 
5) . Density : 1.01 
6) . Dispersion: cold water dispersible


7) . Stability: 90 days (25 °C)


 


3. Usage


1) . The AKD emulsion diluted to a concentration of 3 to 4 percent , adding with slurry tank, or with a metering pump continuously added to the mixing tank , high box or slurry pipe , in general, adding tune headbox best. 
2) . Dosage: cultural paper 0.07 to 0.3% ( pure ) , fruit bag paper 5 to 7% ( pure )


3) . AKD emulsion must comply with cationic starch , polyacrylamide and other units or dual retention system. Adding sequence is generally: cationic starch → AKD → polyacrylamide . Quaternary ammonium type cationic starch as the degree of substitution > 0.015 , a concentration of 1% , the addition of 1 to 1.5 % polyacrylamide ions can , molecular weight of 500 to 8,000,000 , a concentration of 0.1 to 0.2 % is appropriate , add the amount to 2% of cationic starch , is generally 150 ~ 250ppm.


 


4. Packaging and Storage


1) Products using plastic barrel, net weight 200kg or 1000kg. 
2)The drums should have the following signs: product name, model number, manufacturer name , batch number, net weight, production date, product certification, and stamped with the seal of inspection . 
3)Product should be stored in a cool place (5 ~ 30 °C), shall not be open-air exposure , frozen.
