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.
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
yoohong exports woodchips as a solid fuel and raw materials for producing wood pulp. We acquire woodchips either from saw millers or biomass suppliers. yoohong has several sources of quality wood shavings. Wood shavings are either made of single or mixed types of wood. People often use it in gardening, as animal bedding, as cushioning materials and as a fire starter. Type: Mixed wood and pine. yoohong does not collect sawdust. The company collaborates with several sawmills for the direct loading of processed sawdust. yoohong has quality pellets of various sizes and materials. All wood pellets comply with TISI (Thai Industrial Standards Institute). yoohong exports wood briquettes to several developing countries for industrial applications. Supplies of wood briquettes are not in excess due to the high demand for wood pellets. Herbaceous pellets and briquettes comprise coconut shells and rice husks. They have a slow-burning time, thus suitable for household heating systems. Price varies with supplies and is yet to be updated. Please check with us for the latest price. The product pamphlet (catalogue) is available on request. Visit our website for more information.
Our coconut oil is produced from raw coconut milk. We do this by centrifugal separation and vacuum cleaning without heating. We know how to extract all fractions of water from oil without heating and this is the most important step to obtain premium quality, few people can repeat our quality. Mostly oils are made from already dried coconut raw materials: from dry chips, copra or desiccated coconut, but this is always low-quality oil and does not have a high biological value. We take fresh organic coconuts, extract the raw coconut pulp, make coconut milk from it and separate the oil from this fresh and raw milk without heating. And imagine that the whole process takes place without stops and delays, conditionally after the start of production in an hour in the jar we clog the freshest, crude and raw oil. For 1 liter of oil we take 13 fresh coconuts. Our oil is tastier, more fragrant, fresher - and it is noticeable immediately. We can send samples so that the chief food technologist of your company can test and everyone will be convinced of this. The other, invisible part is utility. Our oil contains 50-52% lauric acid and 64% MCT of medium-chain fatty acids, which are very useful for the body. Many articles and books have been written about the benefits of coconut oil. We can collect such conclusions and use them for marketing: Strengthens the immune system, Improves hormonal balance, Stimulating the metabolism, Increases the energy level, Fights germs and viruses , Protects the heart - improves the cholesterol ratio, Improves digestion and absorption of nutrients, Supports thyroid function, Helps in weight loss by reducing visceral fat, Improves insulin secretion and blood glucose utilization, Blocks the harmful effects of many toxins and free radicals, It helps in the treatment of degenerative, autoimmune diseases. Does not oxidize fast, Does not emit carcinogens. It is natural antioxidant, antiseptic. It is an alkaline product. Relieves chronic inflammation. All that means that coconut oil not only a delicious food but also a Universal natural medicine.
