| HJ-300 Surface sizing agent |
| HJ-300 surface sizing agent is one kind of cationic emulsion type of paper surface sizing agent, which is developed by our company recently. As one kind of cationic polymer paper surface sizing agent, it is widely used in semi-chemical corrugated paper, copy paper, printing paper, white cardboard paper, carton paper & art paper; specially it can improve the performance of semi-chemical corrugated paper. |

| Function & uses: |
It is multi-functional synthetic polymer, and can offer good affinity and waterproof capacity to fiber. It can be used in the sizing & coating of white cardboard paper, carton paper & art paper. It can work with starch to improve the surface performance and replace the sizing agent in the pulp. Moreover, it can clean the papermaking environment and lower the cost. |
| Characteristics: |
It can offer excellent water resistance. It can be used in the coating of white cardboard paper, carton paper & art paper. The surface water adsorption is not more than 50%, thus it can be the substitute of sizing agent in rosin and AKD paste.
It is non-toxic matter; it can be used in the food packing paper.
This surface sizing agent can work with anion and non-ion auxiliaries, direct dyes and optical brightener.
It the normal dose, this product doesn't low the surface tension of liquid and produce foams.
The paper has been sized after it is processed in the sizing machine; the baking temperature is 80°C, which is good for sizing. |
| Dosage: |
1. The concentration of starch liquid is 5.0%-8.0% .
2. Add 1/3-1/2 of water and starch, stir, heated in 95°C.
3. At the gelatinization point, warming for 20 minutes, add water until the temperature is 60°C and below
4. Add this product, stir for 5 minutes.
5. Add 2KG of aluminum sulphate for one stere of solution and stir for 10 minutes, pump to sizing machine
In general, the dosage is 2-4KG/ ton of paper. |
| Precaution: |
Adding surface agent after the starch diluting (diluted starch solution should not exceed 75 ℃), then stirring evenly standby.
Experience has shown that the temperature of glue liquid is about 60 ℃, and could play a better sizing effect.
Surface water of general sizing agent is appropriate in the 6.0-8.0%. |
| Packing & storage: |
Packing: 200KG or 1000KG/plastic
Surface sizing agent has stable performance and storage period is 3 months under the temperature of 4℃-30℃.
It should be kept in ventilating, dry and cool places, and avoid insolation. |
| Security & defence: |
It is no irritating to skin and less irritating to eyes. If it is splashed into eyes, washing with water and send to hospital. Its liquid is non-flammable. |
