III. Function
The dry strength agent is not only a good enhancement, but it also has a higher enhancement effect in waste papers with more fine fiber filler. The use of our dry strength agent can improve paper quality, and it also significantly increase production efficiency, reduce costs and increase economic efficiency.
IV. Method of Application and Notes
1. When diluted with clean water, the dilution multiples of our product is generally about 15 to 30 times. After the product was stirred sufficiently, add uniformly to the slurry in an amount of 5 ~ 10 kg / ton.
2. Adding position that selected could have a full contact with the slurry. Generally choose ingredients pool, high box or import pump.
3. Use a plastic or stainless steel as the material for products storage, dilution tank, piping etc.. Iron-based material will produce corrosion and thickening phenomenon will occur.
4. Do not mix with Other Chemicals.
V. Packing
1000 kg barrels, or according to user requirements.

Papermaking dry strengthen agent is our company`s new and self-developed products that using imported raw materials. Its mechanism of action is: Dry Strength Agent use polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber. Dry strength agents in the combination area of long-chain polymers can be deformed, thus increasing the bond toughness. It could improve paper strength by the bridging ability formed by chemical function to make fibers and fibers have "implicated"

Vegetables catch three points in summer
Here we talk about the summer vegetables, including vegetables in the late growth period of spring vegetables, but also include vegetables in the fruiting stage during the summer. At present, spring wolfberry vegetables have entered the late growth stage, and some of the summer vegetables have entered the flowering period. Many farmers have called the telephone to report that the vegetables in the shed are severely choked off. In fact, the summer light is too long, contrary to the growth habits of vegetables, which is the main reason for summer vegetables break. Such as loofah, although the high temperature, but is a short-day plant, such as long hours of sunshine, it will inhibit the flowering of loofah, and then there is a phenomenon of flowering and sitting poorly, break and rest. In hot weather, how to prevent summer vegetables from breaking? The reporter suggested starting from the following points. First, reasonably adjust the lighting and temperature in the shed. Lighting is a key factor in determining the temperature in the shed, so adjusting the lighting and adjusting the temperature is consistent. In general, when the greenhouse temperature exceeds 35°C and persists for more than 2 hours, the flower bud differentiation of vegetables will be hindered, resulting in poor flowering, fruit setting and fruit drop. The current out-of-shelf temperature sometimes exceeds 35°C. If the shade net is not covered in the shed, even if the ventilation is good, the temperature in the shed can easily reach 40°C or more. Therefore, vegetable growers can cover the shade net from 11am to 3pm, or use a sprayer to spray water at the noon at noon, which has a better cooling effect and can increase the flowering fruit setting rate of vegetables. Second, the rational use of growth regulators. At the 3-4 leaves of seedling stage, in order to promote the differentiation of female flowers in vegetables, vegetable farmers can spray ethephon to promote female flower differentiation, but it should be noted that lower concentrations should be used when the temperature is high in summer. After planting, in order to control the growth of the plants, 500 times of melatonin may be sprayed or 1,500 times more love, regulate the vegetative growth and reproductive growth of vegetables, and increase the fruit set rate of vegetables. Again, promptly pick and drop. If the vines are not settled in time and the vines are too small, it is also easy to cause excessive vegetative growth in the vegetables and it is difficult to eat them. For loofah in the late Spring Festival, should be accompanied by picking and picking the heart promptly falling vines; for the growth of early summer more loofah should increase the extent of falling, each falling vine not less than 60 cm, keep the plant height at 120 cm , inhibit vegetative growth. Also pay attention to the management of fertilizer and water in late spring vegetables. Many vegetable farmers believe that anyway, after entering the late growth stage, the output has been reduced, and the management has not been very careful. The number of times of watering and fertilizing should be reduced. In fact, this understanding is wrong. The reporter suggested that summer temperatures should be higher and watering should be timely. In the late growth stage of vegetables, high-nitrogen and potassium fertilizers can be applied along with water to promote plant and fruit growth, and full-water-soluble fertilizer lighthouses, Haolipu and Fangrun can be used to achieve good results. Foliar sprayed with foliar fertilizer containing boron, calcium and other trace elements, such as borax 600 times or 1500 times the speed of boron and 350 times mixed calcium nitrate, to a certain extent, can play a role in the preservation of fruit.
