Early repair of frozen farm machinery
If the weather in winter is cold, if agricultural machinery is not properly kept, it will be prone to freezing accidents. At this time, it is necessary to find out the locations in time and carry out maintenance to ensure the safety of use. Find cracks: 1. Slowly bake in the lower part of the engine with charcoal fire. At the same time, open the water tank mouth and inject warm water. In this way, proceed up and down at the same time until the ice in the frozen area melts completely from the discharge valve. Then close the drain valve and fill it with heat. Water, wipe off external dirt, find cracks. 2. When the machine is frozen, the cracks are unlikely to be on the outside. After the external inspection, the oil pan oil drain bolts can be loosened. If there is water leakage, the oil should be drained, the oil pan removed, and the leaks should be carefully searched. . Overhaul processing: 1. After finding cracks, weld repairs, shimming, or patching with iron plates should be performed as appropriate. 2. If there is a leak in the heat sink of the water tank and the quantity is small, both ends of the water pipe core can be blocked and used. If there are more cracks, weld them before use. Varicella Vaccine(Live)
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, free of animal gelatin, was invented and produced in China, which can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period for good stability. The first approved varicella vaccine with 36 months of validity period in the world. The application of BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.
3.Better protection with high titer and immune performance. Live Bioproducts Pharmaceutical,Live High Potency Medicine,Live Preventive Pharmaceutical,Varicella Biopharmaceutical Live Changchun BCHT Biotechnology Co. , https://www.ccbcht.net
It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Among all released batches of Varicella Vaccine from BCHT, the titer is not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
