Paraffin is mainly composed of solid alkane, odorless and tasteless. It is a white or light yellow translucent solid. Due to its high oil content, it is mainly used to make matches, fiberboard, canvas, etc. When polyolefin additives are added to paraffin wax, its melting point increases and its adhesion and flexibility increase. It is widely used in moisture-proof and waterproof packaging paper, paperboard, surface coating of some textiles and candle production.

Nowadays, beeswax has begun to be used as green food additives, coatings, packaging, additives in edible films, chewing gum and flavour enhancer carriers. Especially beeswax in the freshness of vegetables and fruits transport process, can prevent water evaporation and inhibit the growth of microorganisms, prolong the shelf life of fruits, has a very broad value of use. Fruit wax can preserve the freshness of fruits, can better prevent water loss, prevent the fruit surface from microbial infestation, maintain fruit quality, increase colour, brightness, texture, improve the appearance, prolong the fruit and vegetable hiding period and shelf life. Add beeswax to animal feed, can improve the animal's antibody immunity to disease resistance, promote cell division and growth and development, and no residue, no teratogenic, carcinogenic, mutagenic and other toxic side effects, can be gradually promoted in the breeding industry. In addition, beeswax is a crop growth promoter, can be used as fruit tree elder wax and broken cosmetic trauma on the pests and diseases adhesive. Mixing beeswax and propolis liquid with herbal liquid has a good effect on the prevention and control of fungal diseases of fruit trees, and the nutrients in it can also improve the nutritional imbalance of crops due to the weakening of trees and other reasons.

PFA reaction vessel is an efficient and multifunctional chemical reaction device. Its core advantage lies in the use of PFA (soluble polytetrafluoroethylene) material. PFA has excellent high and low temperature resistance and a wide range of operating temperatures. It can maintain stability in extreme environments and ensure a safe and controllable reaction process. In addition, PFA has extremely high chemical stability and can tolerate almost all chemical solvents, effectively preventing cross-contamination and ensuring the purity of reaction results. Its dielectric properties are excellent, and its electrical insulation is not affected by temperature, providing a stable electrical environment for experiments. In terms of structural design, the PFA reaction tanks are connected with tubes and valves, which can flexibly adjust the reaction process and improve reaction efficiency. At the same time, its transparent and colorless appearance makes the reaction process clear at a glance, making it easy to observe and monitor. In summary, the PFA reaction tank provides strong support for laboratory research with its excellent PFA characteristics and efficient design, and the entire device supports customization. web: https://www.njbinglab.com Phone/Whatsapp/ Wechat :+8615805176994 Mail: rossnjbzh@gmail.com / rossg@njbinglab.com
