Mixed type fishnet antifouling agent

Product manual In recent years, China's “three nets” (ie, cages, nets, and nets) have been breeding fish, shrimp, shellfish, and oysters, and they are in the thousands of kilometers from north to south, as well as inland rivers, lakes, and ponds. The scope is very wide. Fishing nets are usually woven from chemical fiber raw materials (such as PVC). The size of the mesh is different depending on the culture object. The size of the mesh is different. Because the net is soaked in water for a long time, it is very vulnerable to algae, moss and barnacle. Corrosion of non-farming organisms such as dragons, mussels, oysters, and amphipods not only shortens the service life of fishing nets, but also often organizes labor to clean the nets, even changing the net, wasting manpower and material resources and time. Moreover, because the mesh of the fishing net is blocked by a large number of non-aquaculture organisms, hindering the normal exchange of water quality, the breeding organisms lack bait and oxygen, thus seriously affecting the production of aquatic products, so fishing net pollution has become a major problem in the breeding industry. The use of safe and effective antifouling agents is one of the effective means to solve the pollution of fishing nets. Since the 1970s, there have been reports on the research and development of anti-fouling agents for fishing nets at home and abroad, but so far no promotion has been applied. The reasons are: 1 The agents used are highly toxic and unsafe. 2 anti-fouling time is short, the effect is not ideal. 3 The product is sticky, the film forming performance is poor, and the operation is inconvenient. 4 The price is high, it is not convenient to promote the application.LY fishing net antifouling agent is a new generation of environmentally friendly antifouling agent developed by our factory with complete intellectual property rights. It has good antifouling effect, safe use, convenient operation, reasonable price, strong practicability and easy to promote.
Features 1. The antifouling agent has obvious inhibitory effect on non-aquaculture organisms such as algae, moss, mussel and oyster. The anti-fouling period of the net coat treated with the anti-fouling agent is extended by 2-3 times. 
2. The netting treated with antifouling agent will no longer be blocked because it is no longer attached to non-bred organisms, thus ensuring the smooth flow of water inside and outside the cage, rich bait and sufficient oxygen supply, thus shortening the breeding period. (For example, cages can be harvested 1-2 months in advance) to increase aquatic product production (up to 15%). 
3. Net clothing treated with anti-fouling agent, because it is no longer attached to non-cultured organisms, it is no longer necessary to manually remove the net for decontamination or even change the net, thus saving a lot of manpower, material and time. 
4. The netting treated with the antifouling agent can reduce the loss of the tension strength of the netting due to covering a film with good water resistance and wear resistance, and is no longer corroded by other organisms (about 20% reduction each time) ) to extend its useful life. 
5. Net clothing treated with antifouling agent, because the non-breeding organisms are no longer attached, the water flows smoothly. The dissolved oxygen in the water tends to be normal, so the egg parasitic diseases that affect the bacterial diseases of the physiological metabolism of fish, shrimp, shellfish, and scorpions under low oxygen conditions can be greatly reduced. 
6. Since the antifouling agent used is an environmentally friendly product, the film forming agent is excellent in water resistance and wear resistance. Therefore, after using the fishing net, no "three wastes" will be produced and the environment will not be polluted. 
7. For environmentally friendly products, the LD50 of the Shanghai Institute of Preventive Medicine has reached 9260mg/kg, which is an actual non-toxic grade and non-irritating to the skin.
Instructions Use objects: fishing nets, cages and underwater ropes. 
Usage: 1. Soaking method: use container or cement tank, pour the antifouling agent first, stir evenly, then uniformly soak the fishnet in order, and then dry it thoroughly after taking out. It is best to choose when the temperature is high (conditional high temperature drying available, especially good results). After the fishnet is placed in the water for two days, the culture is placed. 
2, brushing method: use the container or cement tank, first pour the antifouling agent, stir evenly, then use the brush to evenly spray the antifouling agent on the fishing net, pay attention to ensure that the inner and outer surfaces of the fishing net are covered with antifouling agent, coated Dry thoroughly after brushing. It is best to choose when the temperature is high (conditional high temperature drying available, especially good results). After the fishnet is placed in the water for two days, the culture is placed.

Precautions 1. In order to achieve the best results, be sure to stir the antifouling agent thoroughly before handling the fishing net. 
2. The netting that is treated before use must remove dirt, dry and clean. 
3. Do a good job of protection during operation. Wear protective gloves when the fishing net is impregnated with antifouling agent. The antifouling agent should avoid direct contact with mouth, eyes and skin. Rinse immediately with water after touching the body. 
4. Since the antifouling agent has good film forming performance, the device after use must be cleaned by dampness, otherwise it is difficult to remove after drying to form a film. 
5. The remaining liquid after use can be packed in plastic drums and reused, but should be stored in a sealed manner to avoid direct sunlight.
Package 25, 50, 200 kg plastic bucket
Storage Sun protection, rainproof, under the specified storage conditions, the shelf life is 18 months from the date of packaging.Allow a little sedimentation, stir well before use, but it does not affect the effect.
