Flame retardants, also known as flame retardants, fire retardant or fire retardant: Give a flammable polymer flame-retardant functional additives; depending on the application is divided into reactive flame retardant and flame retardant. According to the composition, flame retardant include inorganic flame retardants, halogenated flame retardants (organic chloride and: flame dedicated tray dryer, a flame retardant special drying machine, dryer flame retardant agent drying equipment organic bromides), phosphorus-based flame retardants (red phosphorus, phosphate and halogenated phosphate) and nitrogen-based flame retardants. Reactive flame retardant mostly organic halides and organic phosphorus monomer containing a reactive functional group. Product details Overview: flame retardants, also known as flame retardants, fire retardant or fire retardant: Give a flammable polymer flame-retardant functional additives; depending on the application is divided into reactive flame retardant and flame retardant. According to the composition, flame retardant include inorganic flame retardants, halogenated flame retardants (organic chloride and: flame dedicated tray dryer, a flame retardant special drying machine, dryer flame retardant agent drying equipment organic bromides), phosphorus-based flame retardants (red phosphorus, phosphate and halogenated phosphate) and nitrogen-based flame retardants. Reactive flame retardant mostly organic halides and organic phosphorus monomer containing a reactive functional group. In addition, molybdenum compounds having smoke suppression effect, tin compounds and iron compounds 亦属 flame retardant category. Mainly used for flame retardant plastics demand, delay or prevent the plastic, especially polymer-based plastic burning. Retardant special drying equipment disc dryer: Principle: wet material continuously fed from the feeder layer was dried on the dryer upper first disc, harrow arm with a rake leaf rake leaves do make continuous rotary motion of turning copy material , so that the material fully absorb heat index material along the spiral flow through the drying disc surface, the material in the small drying plate is transferred to the outer edge and the outer edge of the outer edge of the falls beneath the large drying trays and dried in a large tray inward movement of material from the lower middle blanking mouth fall into the small drying plate, the size of the drying plates are arranged alternately, the material can be continuous through the whole dryer, heating medium through the hollow of the dry plate. Heating medium is divided into two groups by the end of the drying trays into the dry disk, so that the material is heated more evenly, derived from the other end. The dried material falls from the last layer of drying plate housing bottom, finally rake leaves transferred to the discharge port, and by the screw conveyor discharge. The moisture evaporates from the material after the escape, and finally discharged by the induced draft fan. Advantages: 1. heat out of the way: the same industry manufacturers design disc dryer is a single source of imports, in the presence of steam tray short circuit, uneven heating of the material on the disc surface. And I designed a double inlet, double out, so that heat distribution is more uniform and out, the disk material absorbing more fully, the thermal efficiency is improved. 2. Improved rake arms: the same industry manufacturers disc dryer rake arm is often the case in the production process of bending, the company dedicated to improving the response to this phenomenon, the use of 38 * 5mm thick steel tubes inserted in circular tube Steel strengthened so that the loading capacity of up to rake arm 800kg, thus avoiding bending phenomenon. 3. Disk uneven: for the problem with the industry manufacturers of products that is difficult to avoid, the company conducted a number of tests, and finally a good solution to this problem. Blanking the inner surface of the outer gear ring binder tape and disk circle are small disposable steel drums molding, pressing on the outer edge of the market for the arc, arc suppression small disk, hard disk so that greatly enhanced while more smooth. The disk material remained and more scratch is not clean: the same industry manufacturers still use the original pressing blade, horizontal easy to plot the cutting edge material, direct flank bent blade weight too light, resulting in a lot of disk material remained more, especially high density material more difficult to scrape. And I improved blade several times, standing hand-thick steel plate welded made of vertical perforated board looper to rake arm rotation more flexible. Two intermediate plates using round support, flank arc transition, a high degree of agreement with the disk, so as to solve the problem of feeding the disc area, but also to avoid the product material. Note: For heat-sensitive, explosive and the volume of recovered materials need to be in order and dried in a vacuum, with industry manufacturers of equipment can only reach a vacuum of -0.07 --- 0.075Mpa, and I designed the production disc dryer can reach more than -0.092MPa vacuum. My company's disc dryer after starting the pump, plus the time to work through the material rotate up and down four bucket configuration 8 electric vacuum valve, thus ensuring a degree of vacuum barrel.
