"National Drying Technology and Equipment Engineering Technology Research Center" is based on Tianhua Chemical Machinery and Automation Research and Design Institute. Since it was formally approved by the Ministry of Science and Technology in November last year, the task of engineering technology development has been fully carried out. Relying on the large-scale drying technology and equipment localization research and development achieved gratifying results: the steel industry coke oven coal moisture control device and the petrochemical industry million tons grade PTA (pure terephthalic acid) drying technology and equipment to achieve the current international advanced technology of the same kind Level. After the successful use of the PTA dryer developed by the National Drying Technology Center at the 325,000 tpa/year PTA plant of Luoyang branch of Sinopec (600028), they continued to explore CTA/PTA (coarse terephthalic acid/pure terephthalic acid). Drying theory and industrial tests verify and perfect the CTA/PTA drying mathematical model and master the key technology of CTA/PTA drying process and equipment design. In 2007, they took delivery of the 600,000-ton/year PTA CTA/PTA dryer of Jialong Chemical Fiber Corporation. In February 2008, the center also contracted a Sinopec (600028) Yizheng chemical fiber 1 million tons/year PTA project CTA/PTA dryer development contract. Yizheng Chemical Fiber's 1 million tons/year PTA project adopts the process technology of China's independent intellectual property rights, and the supporting CTA/PTA dryer is also the largest steam tube rotary dryer independently developed by China. The dryer will be delivered in March 2009. installation.
China 42mm Split Set Stabilizer,Friction Bolt,Split Set Bolt supplier & manufacturer, offer low price, high quality Mining Bolt,Split Set Rock Bolts, etc.
42mm Split set bolt is also called "split set stabilizer". It was successfully developed by American Professor Scott in the early 1970s. It was used as a patented product by Ingersoll Rand for mining support. In the early 1980s, the Beijing Institute of Well Construction conducted exploratory tests on slotted pipe anchors in the laboratory and achieved good results. Later, it was gradually promoted and applied in the coal system.
42mm Split set bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force.
42mm Split set bolt has good supporting effect. Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.
