According to the relationship bewteen Paper Making Machine and coating machine, this series of paper coating machine is divided into online coating machine and offline coating machine. For different applications of coating paper, the coating mode is divided into single-side coating and double-side coating, each side can be coated one or more times. The coating machine is mainly uses air knife coater and blade coater, consisting of unwind system, coater, drying system, gloss calender system, regulating and finishing, reeling section and transmission system etc.

Central Northwest Oilfield Branch Sinopec Tahe Oil Plant technicians independently developed electric pump well liner hanger new technical devices, through continuous improvement in four inefficient Inoue recent experiment has achieved ultra-efficient economic development of the desired effect, as a guide The latter part of the block on the production has important strategic significance.
The Tahe carbonate reservoir is affected by factors such as oil thickening, deep oil infiltration point of infiltration, deep pumping of lower oil and poor mixing of mixed materials. The common faults of pumping thick suction pump and electric pumping well during mechanical lift High rate, check the pump cycle is short, the output, mixed dilute the serious loss of oil, the problem of cost pressure. The factory's technical staff for these issues, after more than a year of continuous exploration research and experiment, developed a set of electric pump shaft suspension device, and in March this year won the national new practical patented technology. The new device reached the pump does not assume the case of tail pipe tension to achieve the pump hanging depth and mixed with the mixing point separation, the average depth of the pump hanging more than 2700 meters case, the mixing point down 5000 meters, extended Thin oil and heavy oil mixing time to mix at higher temperatures, not only to achieve the conservation of thin oil, to ensure a stable liquid out of the question, the problem of mechanical lifting has been greatly improved, reducing the electric pump well Abnormal rate, well rate, improve the operational life.
This year, the plant for mechanical lifting can not be used in 12 District 2 Residential Area, 4 Residential North Reservoir, built a self-developed 21 sets of electric pump shaft tail suspension, respectively, in the late waterflooding basic failure of low yield and low efficiency The TH12216, TH12425, TH12226, TH12410CH wells put into use. January 12 put into operation TH12216 wells, tail pipe plus linked to 5135 meters, the current Nissan 41 tons, a total of 5468 tons of oil production, no water; February 24 put into operation TH12425 well, Nissan 34 tons of non-water, with a cumulative 2703 Ton; TH12226 wells put into operation on April 23, 474 tons of oil accumulated; on May 10 put into operation TH12410CH wells, 143 tons of oil production. Single well of four wells daily output of 118 tons, compared with water injection for oil production from thin heavy oil to reduce 0.9, the equivalent of 100 tons of heavy oil per diluted oil savings of 90 tons. At present, well TH12439 is under construction and there are plans for 5 wells such as TH12417.
The successful application of the new national patented device in Tahe Oilfield has re-established the development of ultra-heavy oil reservoirs in Block 2, Block 2 and Block 4 in the northern part of the country and re-argues and evaluates the previously difficult-to-use blocks to increase reserves Economic utilization, but also has a universal value of popularization and application to ease the shortage of dilute oil supply situation for the oil-efficient heavy oil reservoir economic development provides a new technical means.
