2016/5/28      view:
Eve of the liberation, China hose tape industry is semi-paralyzed. After the founding of New China, hose tape industry opened a new chapter of development, becoming the world's manufacturing center of industrial hose tape, hose tape capacity, production, consumption volume ranking first in the world, a truly great power hose tape, to power forward. China hose tape industry has become the focus of attention of the world rubber industry, it affects the eyes of my colleagues in the world.
Together with the Republic started
In the initial stage of a century in the rubber industry, particularly hose tape industry behind only mainland China in Shanghai, Qingdao, Guangzhou, Tianjin and other coastal cities have a few small businesses, and more for the Japanese. Eve of the liberation, hose tape industry is significantly reduced. According to the Shanghai Rubber local chronicles, the 1949 Shanghai tape production fell 56 percent over 1948, hose tape industry in a state of semi-paralysis.
Beginning of the birth of new China, the four major industrial raw materials as steel, coal, petroleum, rubber became the West "embargo" strategic materials. In 1951, the Central People's Government issued a call "We must build our own rubber base", ensure that the new China include industrial rubber hose tape, including the required raw rubber material supply.
August 29, 1952, Qingdao Rubber Factory sixth plant, the production cycle tire and rubber hose, rubber named Shandong Plant third branch. 1953 changed the state of the second rubber factory third plant will be transferred to the product cycle tire Qingdao with the Thai Rubber Factory, and has built a conveyor belt and V workshop workshop. July 1956 the plant was separated from the plant, the establishment of state-owned Qingdao Rubber Liu Chang, the same year the plant exports to North Korea and Cuba, conveyor belts, hose tape began the history of Chinese exports. During 1958 to 1964, with the development of industry, agriculture and transportation industry, new plants have tape hose into production.
The 1960s and 1970s, the CPC Central Committee and State Council made a major strategic decision juniors line construction and small three-line construction, so concentrated in a few coastal cities of hose tape industry radiation to the Chinese mainland. Country from the current international environmental considerations relevant part of the new industrial plant has a significant impact on the national economy and national defense construction built in the southwest and northwest areas of strategic depth, called the Third Front, with respect to the northwest and southwest of the Third Front, central and coastal hinterland called small three lines. Coupled with the "support mainland's economic construction," Before and after the call and the requirements of the whole country, Chinese hose tape industry in the country to take root and bear fruit.
Several five-year implementation plan to make hose tape industry has entered a stable stage of development, the country emerging new results. Reform and opening up began in 1978, China is changing the hose tape industry overall backwardness.
