Imported Premium Fire Retardant Flame retardants, functional auxiliaries endowed with inflammable polymer flammability, mainly designed for flame retardancy of polymer materials; There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to their usage.

The additive type flame retardant is added to the polymer by mechanical mixing method to make the polymer flame retardant. At present, the additive type flame retardant mainly includes organic flame retardant and inorganic flame retardant, halogenated flame retardant (organic chloride and organic bromide) and non-halogenated flame retardant. Organics are some flame retardants represented by bromine, phosphorus and nitrogen systems, nitrogen systems, red phosphorus and compounds, while inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide and silicon systems.
Harvesting Techniques
Whether harvesting is timely and harvesting technology is appropriate has a direct impact on the quality and output of the products. 1, castration is timely. Castration is generally selected at the end of the first trimester or early flowering stage of the alfalfa, with an average of 100 planting rate of 5% or less, and the rate of flowering of the 100 plants at the end of harvesting should not exceed 10% because of the crude protein content after drying. Can maintain more than 17.5% (export product standard is not less than 17%). 2, the height of castration should be appropriate. The height of cutting and cutting should be controlled within 5-10 cm. Too high a stubble directly affects the yield of alfalfa. If the alfalfa stays too low, it will damage new sprouts of alfalfa and it is also not conducive to mechanical operation. 3, drying technology should be properly. After the castration in Tianjin, the field is naturally dry. After drying for one day, when the water content of the upper layer is about 30%-40%, it can be sun-dried and ridged in the morning or evening. At this time, the leaves of the alfalfa are not easy to fall off, thereby reducing the loss rate. If two lines are ridged or ridden in three lines, they should be determined depending on the output of the plutonium to ensure that the bundling machine feeds properly and the bundling speed is increased. 4, the timing of baling should be timely. After being castrated, they should be air-dried for 2-3 days when there is sufficient sunshine in the sunny days. When the water content is below 18%, they are tied in the morning or evening to reduce the loss and breakage of the alfalfa leaves. Care should be taken not to knock out excessively wet earthworms, clods, and rotted grasses into the bale to prevent spoilage after baling. 5, straw bales should be appropriate. After tying the bales, they should be warehousing or palletizing as soon as possible. Bottom grass bales should not be in direct contact with the ground in order to avoid flooding. The rain should be covered with rain-proof facilities.
