Detailed Description
Polyester steel-like brown wire —— new rubber framework material
Polyester steel-like brown wire is the newest rubber reinforced material researched and developed by Weihai Tianchenghualun Special Belt Core Co., Ltd, (The patent No. is ZL0010179.X). The traditional rubber framework material are polyester cord，hard laid wire rope，aramid fiber and other fiber rope structures however polyester steel brown wire is an overall solid core structure, with no requirement of twisting, which fully reflects the physical characteristic of fatigue resistance of polyester materials and solves the traditional problem of unequal length in fiber structure, the product has the advantages of a uniform load, no looseness, no stretching, flex resistance, good adhesion， high strength and so on . It greatly improves and balanced the service life of rubber products and maintenance free, so that enterprises can replace the products regularly.
Polyester steel-like brown wire rubber framework material has passed the appraisal sponsored by identification commission on November 22, 2010 in Beijing. The rubber v-belts taking polyester steel-like brown wire as the framework material produced by the Chinese Shandong Qingdao the No.6 rubber factory , have been applied inDaqing Oil Field, Chinese Liaohe River oil field, China Shengli Oilfield, indicating that the service life compared to the counterpart in polyester cotton rope framework strcture has prolonged 5~10 times .The expert believed that the polyester steel-like brown wire rubber framework material has filled the domestic gap belonging to the international advanced standard.
Polyester steel-like brown wire rubber framework material is an important breakthrough in the international rubber industry for the recent decades, the substitution product of polyester soft rope，hard rope，aramid fiber and other fiber materials ,now it is widely used in rubber transmission belt , medium and small conveyor fields, as the development of the company , it will expand into rubber hose, tire and other field .
Characters of polyester steel-like brown wire maintenance free transmission belts
1. Applying polyester steel-like brown wire an overall solid core structure and without the system of twisting as the framework material, taking the place of the polyester soft rope, hard rope, aramid fiber and other fiber framework materials; service life increases 5 to10 times ;
2. It is not necessary to adjust the tension once the right one, maintenance free rate reaches 97%
3. High tenacity, resistant to impact, appropriated for overload devices;
4. Having no significant elongation, particularly applicable to transmission devices with demanding requirement in length stability;
5. Improving work efficiency.
Polyester steel-like brown wire ——heavy- horsepower maintenance free banded v-belts
Take oilfield exploration industry as the example :Transmissions belts in oilfields exploration industry have demanding requirements，the international average service life in traditional transmission belts is 2 to 4 months, polyester steel-like brown wire transmission belts tested in Da qing oilfield ，showing that it’s not necessary to adjust tension and maintenance free, the average service life is more than 12months, reaching the international advanced level.
