For a long time, there has been a saying in some places: "Sheep buckwheat, two without loss," "Pig mouth odor, smashed wheat grown into beans." In fact, this is completely wrong.
Practice has proved that after wheat seedlings are fed by pigs, sheep, and other livestock, the area of ​​green leaf and ground cover are reduced, and the damage from freezing is intensified. The spring returns to late spring, and the percentage of tillers per spike and grain weight per spike are significantly reduced. According to investigations by relevant authorities and manual simulation of leaf cutting experiments, the wheat fields that were eaten by sheep were reduced by 5.04% in light, 31.3% in three times, 51.7% in continuous crops, and 14.2% to 32% in Maian wheat. The reduction in production of pig arches was 36.4%, and the production of artificially simulated leaf cuts was 8.8%-23%. To this end, remind the farmer friends that they must be accounted for, and do not do stupid things that are fat to the sheep and lose a quarter of grain.
With the constant improvement of economic level, people` requirements on the quality of paper are increasing high. A great number of paper products must have excellent resistance to fracture under moist state, in other words, must have a certain degree of wet strength. While the traditional papermaking wet strength agents are urea resin and melamino-formaldehyde, both belonging to formaldehyde resin with intense pungent smell and certain toxicity, and can be used in acid condition to acquire the wet strength. However the whiteness will descend a lot and the paper will be weak after the finished paper acquiring the wet strength. Polyamide polyamine epichlorohydrin resin (PAE) is water soluble, cationoid and thermosetting resin. This product is a non-formaldehyde polymer, non-toxic and tasteless, with a wide range of PH value and suitable for acid, neutral or slightly alkaline papermaking conditions, as well as the acid condition. Wet strength effect is better than the urea-formaldehyde resins and melamine formaldehyde resin. PAE resin, which is an excellent wet strength agent, develops fast in recent years with China`s paper industry development.
The high performance papermaking wet strength agent (PAE) that we produced has been widely used in a great amount of domestic factories and the finished paper products` wet strength index has surpass the similar products in domestic and foreign counties.

2. Application
PAE active ingredient is polyamide epichlorohydrin thermosetting resins that can be used as below:
1. Paper products with the need for drying or wiping water, such as: napkins, wet tissue paper, facial tissue, paper napkins, kitchen towels, wiping window paper, industrial wipes, lens wiping paper, cosmetic paper etc.;
2. Outdoor paper: such as kraft paper, packing paper, outdoor poster paper, construction paper, sack paper, map paper, germinating paper, fruit bag paper;
3. Wet wrapping materials: such as paper cups paper, meat paper, wrapping paper and boxes for fruits and vegetables, frozen and refined food packaging paper, pressure sensitive copy paper, filter paper, leaching processing paper and tea bag paper;
4. Paper soaked in water: as photographic raw paper. Instead of disposable textile products, such as hospital bed sheets, toilet paper and other disposable hospital garb.
Other issues such as cigarette paper, paper used for invoices.
PAE, as wet strength agent excellent efficiency (PAE), has been widely accepted by the papermaking industry
5. Storage Condition
Storage: Avoid direct sunlight, prohibiting contact with concentrated acids. Storage temperature is 0 ~ 35 ℃and the product can be stored for up to 3 months under 5 ~ 35 ℃.
4.Package and Transportation Safety
Package: 200 kg polyethylene barrels or 1000 kg IBC barrels.
Transportation: The product is non-flammable, non-explosive and low corrosive and non-dangerous. It can use plastic buckets as containers on railways, highways, aviation, marine to achieve the purpose of the safe transport, and if the leaking occurs during transportation, you can simply rinse on the spot.
