Identification of scientific methods for fishery drugs

In recent years, there are many varieties of fishery medicines, which are mixed, so that users are at a loss in choosing. This article elaborates on the packaging of fishery medicines, the appearance of products, and the “three certificates” in order to provide users with a good selection of fishery medicines as a reference. First, check the packaging 1. Veterinary drug products (except bulk drugs) must use both the inner package label and the outer package label. The inner packaging label must be marked with "Veterinary use" logo, name of veterinary drug, indication (or function and indication), content/packing specification, production license number, approval number or "imported veterinary drug registration license" certificate number, production lot number , valid period, production company information (company name, address, contact information), etc. The packaging label must indicate the veterinary label, name of the veterinary drug, main ingredient, indication (or function and indication), usage and dosage, content/packing specification, production license number, approval number or "imported veterinary drug registration permit" Certificate number, production lot number, expiration date, withdrawal period, storage, package quantity, production company information, etc. 2. Check the registered trademark. Regular fishery and fishery manufacturers apply for a registered trademark. Registered trademarks (patterns, drawings, texts, etc.) must be marked on the packaging, labels, and instructions of veterinary drugs with the words “registered trademark” or a registration mark. Fake veterinary drugs produced by illegal manufacturers are often not trademarked or use unregistered trademarks. 3. Check whether fishery medicines that are declared or eliminated by the country are eliminated or banned from production, sales and use. For example: Some fishery medicines have been proven for a long time, their efficacy is not reliable, and some toxic and side effects are serious. Some fishery products have exceeded the standard in aquatic products after use and endanger human health. The conditional users can pay attention to the sampling inspection report issued by the Ministry of Agriculture on the official website (WWW.agri.gov.cn). Second, visual product appearance 1. Powder packaging should be complete, no significant difference in the amount of filling, no flatulence phenomenon. Dry powder is loose, uniform particles, uniform color, no odor, deliquescence, mildew, agglomerate, sticky, insects and other conditions. 2. The liquid agent should be opened and the bottle should be observed with no significant difference in its loading. The container should be intact, uniform and free from leakage. Bottles should be sealed with wax. The container should be completely dissolved after adding the prescribed solvent. The solution should be clear and free of foreign matter. The color of the solution should be the same, clear, no foreign matter, no precipitate or turbidity; individual products are allowed to precipitate a small amount of crystals in winter, and should be completely dissolved after heating. Otherwise, floc and other abnormal phenomena may not be used. 3. The outer packaging of the tablet is intact, the appearance should be neat, complete, uniform in color, the surface should be smooth, no spots, numbness, proper hardness, and the dissolution time in the water after testing should meet the product requirements. 4. Chinese herbal medicine mainly depends on whether it absorbs mildew, insects, or flatulence. It is not appropriate to continue to use these phenomena. The fineness of the powder should meet the product requirements. In the case of Chinese herbal medicine tablets, there should be no adhesion of the tablets, no melting, moldy appearance, the edges should be neat, and there should be no loose pieces, splinters, roughness, uneven thickness, etc. 5. Injectables are expired, the transparency of the injection is not in conformity with regulations, discoloration, abnormalities, cracks in the container, or the looseness of the stopper. The suspension is shaken and delaminated quickly or has a clot. The freeze-dried product has lost its vacuum. Drugs that are loosely packed in the bottle and stuck to the bottle should not be used. 3. Pay attention to the "three licenses" 1. The production license is valid for 5 years. The original license must be re-applied within 6 months before the expiration of the production license. At the same time, the production license shall be subject to the annual inspection system. The production license shall include the license number, company name, legal representative, person in charge of the company, type of company, registered address, production address, production scope, issuing authority, date of issuance, and expiration date. An enterprise may not manufacture products outside the scope of the license, and shall immediately stop the production and sales of the products after revoking the production license. The Announcement No. 202 issued by the Ministry of Agriculture of the People's Republic of China stipulates that starting from January 1, 2004, the approval number of any product shall not be renewed to any enterprise that has not obtained the GMP certification for veterinary drugs. The veterinary drug production industry must reach the national veterinary drug production industry before December 31, 2005. Good GMP (Good Manufacturing Practice), therefore if GMP is not passed, GMP will not allow it to produce, and there will be no production license. 2. The number of approval documents for fish and fishery medicine must have an approval number issued by the Ministry of Agriculture or the provincial animal husbandry and veterinary administrative department. The imported veterinary drugs are issued by the Ministry of Agriculture and must be registered by the Ministry of Agriculture. The prescribed uniform numbering format. 1 veterinary chemical (antibiotic) product or feed drug additive approval number format: Beijing (abbreviation issued by provinces, autonomous regions, and municipalities directly under the Central Government, issued by the Ministry of Agriculture for "agriculture") veterinary drug word (or drug add word) XXXX (year) X (represents western veterinary drugs) XXX (provincial serial number issued by the Ministry of Agriculture and veterinary drug manufacturer serial number issued by the provincial government) XXX (varieties), such as Beijing Veterinary Drugs (2000) X308603. It should be noted that: “X” is a veterinary product with pure Chinese herbal medicine, “S” is a biological product, “J” is a preparation of imported raw materials, and “F” is a compound veterinary drug of Chinese and Western medicine. The packaging products for the packaging (domestic or imported large-packaged veterinary drug products are packaged as small packages) g The products produced during the trial production of the first and second new veterinary drugs and new biological products are trial products, and shall be added before the "word". Word. 2 Biological product approval number format: Health drug word XXXX (year code) XX (biopharmaceutical plant number) X (category code) XXX (variety code). Do not use the document number or other number to replace the imitation approval number. The period of validity of the fishery drug approval number is 5 years. The fishery drug manufacturer should apply for re-registration to the original examination and approval authority within 6 months before the expiry of the expiry date. After the expiry date, the original fisherman's approval number will be set aside and the fishery drug manufacturer may not continue production. , operating the original approval number of products. It should be pointed out that the development of fishery medicine is later than that of traditional veterinary drugs mainly composed of livestock and poultry. Some of the fishery medicines originate from traditional veterinary drugs, and the fishery drugs are managed by the Animal Husbandry and Veterinary Bureau. Therefore, the batch number of fishery medicine preparations is determined by the batch number of veterinary drugs. The fishery medicine preparation can only get the batch number if it meets certain standards, and the fishery medicine with batch number has certain guarantee on the quality. 3. Production batch number It is a group of numbers or letters plus numbers used to identify "batch", which is generally the date of shipment of the batch of fishery medicine and consists of two digits of the year, month, and day of production time, but there are exceptions. A part of the fishery drugs has a valid period, and the validity period starts from the date of production (based on the production lot number). If it exceeds the valid period, it will be expired fishery medicine. 4. There is a variety of trade names for fishery medicines that are often distinguished by the same main ingredient, such as fishery medicines that contain chlorine dioxide as the main ingredient, and their trade names include gram of disease, bacillus, bactericide, etc. This is commercially allowable. The user should carefully read the label according to the purpose of treatment, recognize the main components and contents of the product, and then compare the similar products of the respective manufacturers, and finally select the product with high quality and low price. In fact, depending on the above methods, it is not always possible to fully identify the inferiority of fishery medicines. There are some methods for identifying drugs in the “Veterinary of the People's Republic of China” (2000) or the “Handbook of Fishery Drugs” (Second Edition). The user can refer to the measurement. With the strengthening of the management of fishery drugs, the establishment of a database of fishery medicine products to achieve online search E, the implementation of fishery medicine anti-counterfeit labels, product quality inspection certificates, etc., will facilitate the identification of fishery medicines. When purchasing fishery drugs, the user should also pay attention to requesting invoices and other credentials. If there are quality problems, he/she should pay attention to the preservation of fishery medicine samples so that the quality disputes can be solved. (China Fisheries)

Wet Strength Agent

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.

1. Performance Indicators

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.
