Alkyl ketene dimer (AKD) is most common neutral/ alkaline sizing agent. It is an Internal sizing agents. Structurally, it is unsaturated lactones and it is synthesized from fatty acids. Physically it is waxy like milky emulsion chemicals. It has less corrosive to the papermaking machine than acid sizing. For cultural paper and packing paper.
CM Chemical has developed the following products.
Advantage
Alkaline sizing system reduces corrosion of paper machine equipment.
Less foam produced by the approach system than the acidic rosin system.
AKD pulp sizing cost less than rosin sizing.
Hard- sizing can be applied, and the stocking sizing degree is proportional AKD usage.
Features
Mature production process, easy application, simple adding equipment.
High self-retention, good sizing effect, fast curing rate.
Strong anti-interference and good stability.
Good anti-moisture effect for the paper, can effectively prevent the reduction of RCT.
Surface Sizing Agent is a synthetic copolymer of high molecular emulsifier and styrene ester monomer. It mixes well with starch and provides the starch coating with excellent cross-linking strength and hydrophobic property. It's featured by low consumption, free odor, low foaming, long foam inhibition period and excellent film forming, and it can significantly improve the water resistance capability and ring pressure strength of corrugated paper and cardboard paper. It is a sufficient substitute for internal sizing agent and has no maturation period. It is applicable to various types of surface sizing machines.
Advantage:
Low consumption, low sizing than internal (pulp) sizing and AKD type of surface sizing. The paper can be fully cured after reeling down. Strong water-resistant performance.
Features:
The cationic surface sizing agent needs some aluminum sulfate to perform well.
The product series adapt to all high and low speed paper machines.
Good Moisture Resistance, effectively prevent the reduction of RCT.
Anionic the surface strength for culture for cultural paper.
are water-soluble polymer products. The most commonly used solutions are formulated with polyamide-epichlorohydrin (PAE) resin chemistry and are intended primarily for the consumer market. PAE resins function in neutral/alkaline papermaking processes. They have a high level of Wet strength agent permanence, help improve machine efficiency and do not adversely affect paper absorbency.
Advantage:
Paper production efficiency: After using the product, the paper production efficiency will be improved.
Wet strength effect: Easy to absorb water, with obvious anti-scratches effect.
With excellent performance of keeping luster and color, do not reduce the whiteness of original fiber.
With stable chemical properties and good compatibility.
Features:
The product has good characteristic to reduce the problem of dropping off powder which is can widely used in the tissue, package paper, culture paper and other kinds of wet strength of paper production.
ANIONIC POLYACRYLAMIDE
The polyacrylamide powder particles with anionic charge is suitable for different papermaking sewage floatation solid-liquid separation and sludge filtration dehydration according to the degree of hydrolysis.
CATIONIC POLYACRYLAMIDE
According to the different degrees of cation, the cationic charge of polyacrylamide powder particles are applied to different papermaking sewage flotation and sludge filtration. For the solid-liquid separation of papermaking wastewater, cationic polyacrylamide can effectively collect the solid content to form large and strong floc which can achieve ideal air flotation and sedimentation effect to ensure. The clarity of the filtrate. For the sludge filter dehydration, cationic polyacrylamide can effectively help form large and strong floc to remove water in the sludge and improve the dryness of sludge residue.
Advantage:
Removal of heavy metals and chemicals.
Residual protection against contamination.
Visual improvement of water and acceptability.
Features:
Cationic and anionic flocculants and thus can be used in a wide pH range. It is suitable for the treatment of wastewater, which is difficult for a single chargeable flocculant, especially in water-soluble dye wastewater decolorization.
Defoamer is a special polyether compound defoamer for papermaking. It has de-foaming and antifoaming properties with strong surfactant action and long duration. It can control the whitewater system foam of newsprint, cultural paper and wrapping paper machine, improve the dewatering ability, and control the foam of the sizing system without affecting the sizing performance. This product is free of mineral hydrocarbons and is an eco-friendly product.
Advantage:
Defoamer has strong de-foaming, anti foaming and degassing capabilities and lasts for a long time.
Defoamer has good compatibility and does not conflict with other chemicals in the papermaking system.
Can effectively improve dehydration, reduce pinholes and bubbles on paper, reduce the frequency of paper breaks, and improve production efficiency.
Can improve the retention rate and reduce the load on the pump, pressure screen.
Features:
Defoamer product is a low viscosity and a facility to spread rapidly on foamy surfaces. It has affinity to the air-liquid surface where it destabilizes the foam lamellas. This causes rupture of the air bubbles and breakdown of surface foam. Entrapped air bubbles are agglomerated, and the larger bubbles rise to the surface of the bulk liquid more quickly.
Solid Retention Polymer
Retention agent is a water-soluble, linear organic polymer.
Could enhance the drainage of the wire, improve the retention of small fibers.
Advantage:
Improve the quality of the paper, such as bonding strength, tensile strength.
Save cost by increasing filler retention.
Improve whitewater circulation system.
Improve paper formation.
Improve drainage efficiency.
Features:
The best retention of fine particles and colloids in the papermaking process normally occurs when the zeta potential is near to zero and retention aid doing that. The main functions of retention aid are following:
Improve the quality of the paper, such as bonding strength, tensile strength.
Reduced wet-end additives and sizing usage.
Improves paper machine runnability
Native tapioca starch is a white powder obtained from cassava root, comprising of small glucose molecules that form long amylopectin chains.
This starch is almost insoluble in water and produces a clear, glossy gel when heated. It is a popular thickener and binding agent in food processing.
Two primary types of tapioca starch are available: native tapioca starch, in its unmodified form, is mainly utilized in the food industry, whereas foodgrade modified tapioca starch is chemically enhanced to enhance its functionality, commonly used in processed foods and industrial applications such as papermaking and textile manufacturing.
Benzson is a company that specializes in procurement and procurement. For all types of tapioca starch, we have strengths in finding quality raw materials that meet the needs of customers. And is also a company that supports fast delivery because the company has made an inventory to respond to the needs of customers as well.
