JSC Holography Industry: Products of Shanghai Shensheng are reliable.
JSC Holography Industry, one of the two biggest holography technology companies in the world, met Shanghai Shensheng on exhibition in 2014 and asked Shanghai Shensheng for process solution and supply equipments to their new pilot plants in Minsk, Belarus.
The whole process contains dozens of Explosion Proof pilot scale equipments, including 50L Rotary Evaporator, 100L Jacketed Glass Reactor, 100L Separator, and Thermostat.
The most admirable feature of the rotary evaporator by the users is the unique mechanical sealing. Due to the corrosion of various solvents, as well as high temperature and continuous rotational friction, seals (typically O-rings or oil seals) which play a decisive role in rotary evaporator has a relatively short life span thus need to be disassembled and replaced periodically, therefore affecting the production process. In addition, the entire replacement process is also time-consuming and annoying to the users. Moreover, the seal ring needs vacuum grease to seal, which jeopardizes the cleanliness of the material. Also during operation, the seal ring produces debris out of friction, thus re-contaminated the reacting materials.
Shanghai Shensheng initiated to apply mechanical seal instead of traditional seal structure in rotary evaporator. Oil-free, clean, durable, resistance to friction, corrosion and high temperature of mechanical seal ensure the durability and high performance of sealing system, which totally frees the users from the trouble of stopping production to replace seal.
JSC Holography Industry is also very satisfied with air-proof of the jacketed glass reactor. To improve the durability and resistance to corrosion, Shanghai Shensheng abandoned the traditional axis sealing system such as O-ring or oil seal in 2006, but started to apply the combination of mechanical seal with Teflon reactor cover lid, which significantly increases the airproof level and stirring stability. The innovative PTFE bottom drain valve ensures no dead space and no leakage.
"Shanghai Shensheng’s products are very impressive. Chinese did a very good job. We have a good understanding with each other on both reaction process and equipment configuration. Now our pilot plant is in operation and working smoothly. We are very happy about that and looking forward to our next pilot." — Dmitry Shumakov, Vice President of JSC Holography Industry
Holography Industry JV was founded in 1998 on the base of LLC "Light Magic". The initiative to establish a national security system for producers and consumers in Belarus and CIS countries was supported by the Administration of the President of the Republic of Belarus. Holography Industry JSC specializes in holographic products manufacture used to mark and identify a wide range of goods, security papers and documents. Holography Industry JSC has already produced over 12 billion of holographic marks and now is one of the two biggest holography technology companies in the world.
