description
Technical Characteristics:
1). Of high mechanical strength, and lon個藍g usage cycle
The compressive strength of this ki習一nd of plastics plates is 7 to 10 time爸紅s higher than that of the wo放也od liner, thus conditio頻民ns such as crushing 到物and flatting of the wire rop朋國e groove, and its us水筆age cycle is above 5紅年 times longer than that of the wood li女車ner.
2). Of wide range of application
The plastic plates are of good resistan下著ce of desiccation and m議暗oisture, avoiding the phe公吧nomenon of the sun cracki章裡ng and rotting of the wood. They a睡煙re especially suitable for using in sev匠商ere environment, such as Min國站ing of large water spray and high c玩我orrosivity, and underground mining木間.
3). Of light proportion and 中業no water absorption
The proportion is 0.98, whic跳北h is lighter than the wood liner a又熱fter absorption, thus t吧鐘he rotational inertia但內 and the reactive power of the equipmen業還t would not be increased.
4). Compression moulding, with 舞人flat surface of the rope場分 groove
They are easy to install. With t說聽he neatly rank of the wi相站re rope, phenomenon 器紙such as locking and skipping of the w電作ire rope could be avoid from happening跳坐, and the usage life of the wir遠河e rope could be extended書土.

4. WSM-3 New Environmental舊文 Asbestos Free Brake Shoe &midd信兵ot;Hoist Brake
Braking, which is a process of therm這店al energy turning into ki玩睡netic energy, is rea慢師lized by the friction of the friction 錢道couples. So the frictio上哥n - static material of the friction c玩紙ouples is the guaran拍離tee of the safety of th銀厭e brake. Brake Shoe is the m老吧ain parts of the hoist資問 brake, if the property of t輛筆he brake shoe, such as t船大he friction coefficient, could not員下 be qualified for the designing requ玩花irement, accidents whi業器ch influence the machinery an體秒d human safety may be caused喝吧 properly.
The brake shoes used in秒那 our country are mainly made of a吃化sbestos material. But there are some 間樹insurmountable shortcomings of the as明用bestos brake shoe:
The thermal conductivity of the asbes從不tos is not very good, the fri地雪ction heat could not di兒笑sappear quickly, thus i店著t causes the thickening of the hot rece湖唱ssion layer and the aggra內河vating of the abrasion, a玩答nd polluting the environmen女化t as well. Especially, th北子e asbestos fiber dust is綠腦 one of the causes that lea鄉做d to human cancer;
Abrasive of high hardness and 樹這Steel Wool are used to increas冷分e the friction coefficient and he北數at dissipating capability;
The intensity of asbestos will reduce a爸吃fter complete dehydration d東訊ecomposition at 650℃ to 讀樂700℃;
Hot recession of the fric謝答tion property of the a兵通sbestos happens frequently.
Environmental Asbestos Free Brake著術 Shoe is a kind of the 如不friction - static material, 線黃which uses resin and fiber re西熱inforced plastics inst雜件ead of asbestos. Its鐘外 characteristics are:
Of high friction coefficient, go線白od mechanical intensity著在, and small heat rece雜弟ssion;
Steel wool and high - hardne讀日ss abrasive free, with lo門北w hardness, it causes small dam可兒age to the brake discs;
Asbestos free, environmental頻唱 friendly;
Of low abrasion, and long u時章sage cycle.
With the strengthening 門道of people’s environmen火友tal awareness and sel藍間f - protection awareness, Environment鐵月al Asbestos Free Brake Shoe, having a widely usage prospe快微ct, will finally take place of t放也he Asbestos Brake Shoe.
