PSA technology is a process for purifying gas mixture. Based on the the physical adsorption of gas molecules with the adsorbent, the process is a reversible working between two pressure states. According to the principle that the impurity components of gas mixture have large adsorption capacity under high pressure and small adsorption capacity under low pressure. Specially, the hydrogen has less adsorption capacity whether high or low pressure. In order to get high product purity, the impurity partial pressure can be increased to adsorb as much as possible under high pressure. Desorption or regeneration of adsorbent under low pressure, impurities can be adsorbed again in the next cycle through by the minimize the residual amount of impurities on the adsorbent. Nitrogen cutting Laser cutting can be divided into oxygen cutting and nitrogen cutting. In oxygen cutting, oxygen participates in combustion, and the melting position temperature close to the boiling point, therefore, high temperature leads to violent reaction and can not ensure smooth section. Because of the oxidation reaction and increased heat affected zone, the cutting quality is relatively poor and prone to quality defects such as cutting seam width, cross-section twill, poor surface roughness and welding slag. In nitrogen cutting, the material is completely melted by laser energy, and nitrogen is blown out of the cutting seam to avoid inappropriate chemical reaction. Based on the cooling and protection of nitrogen, the temperature in the melting point area is relatively low, therefore, the reaction is stable and uniform, the cutting quality is high, the section is fine and smooth, the surface roughness is low, and there is no oxide layer. Generally, the oxygen cutting is faster, the nitrogen cutting is better, and the air cutting is low cost. The purity and pressure of nitrogen affect the laser cutting quality, that the higher pressure, the higher purity of gas, the less residue adhered to the material and the smoother cutting mouth. Auxiliary gas As a high-pressure gas, nitrogen can remove oxygen from the cutting area to assist laser cutting. Therefore, it can improve the cutting quality, eliminate oxidation and prevent discoloration, and improve the adhesion of paint pigment and welding strength. When nitrogen and laser are sprayed from the nozzle coaxially, it will also protect the lens from pollution and blow away the slag of the bottom of the cutting area, so that the cutting process can be carried out smoothly and continuously. The use of nitrogen as an auxiliary gas is conducive to improving the laser absorption rate of metal materials, such as aluminum and copper plates with high reflectivity. For the cutting of ferrous metals, a lot of heat is provided because of the ferrite reaction in the notch area, therefore, using nitrogen as auxiliary gas can accelerate the cutting process and improve the cutting ability and quality. Optical Path & Optical Head Cleaning During optical path cleaning, nitrogen can remove any particles of the laser beam path from the nozzle to the cutting area to prevent any laser distortion and help maintain more accurate cutting. Cleaning the optical head of fiber laser with nitrogen can ensure that the optical system does not contain particles and water. Model Identifiers of Membrane Separation Nitrogen Generator. Note: According to requirements of customer (nitrogen flow / purity / pressure, environment, main uses and special requirements), Binuo Mechanics will be customized for non-standard products.

Tehnologija PSA je nova vrsta tehnologije adsorpcije i odvajanja plina.Privukao je pažnju i natjecao se u svjetskoj industriji za razvoj i istraživanje kada je izašao. PSA tehnologija korištena u industrijskoj proizvodnji 1960-ih.U 1980-ima, PSA tehnologija napravila je proboj u industrijskoj primjeni i postala najpopularnija tehnologija adsorpcije i odvajanja plina u svijetu. PSA tehnologija se uglavnom koristi u odvajanju kisika i dušika, sušenju zraka, pročišćavanju zraka i pročišćavanju vodika.Među njima, odvajanje kisika i dušika je dobivanje dušika ili kisika kombinacijom ugljičnog molekularnog sita i adsorpcije uz promjenu tlaka. Pakiranje hrane punjeno dušikom Ambalaža ispunjena dušikom može zaštititi oblik unutarnje hrane kako bi se spriječilo drobljenje hrskave hrane.Zbog neravnoteže unutarnjeg i vanjskog tlaka, pakiranje punjeno dušikom također može izbjeći vezivanje pakirane hrane pod pritiskom i očvrsnuti teksturu.Kada je materijal za pakiranje oštećen zbog presavijanja površine, pakiranje punjeno dušikom može smanjiti rizik od kvarenja hrane.Hrana nepravilnog oblika također može zadržati ljepotu površine pakiranja. Antiseptik i zaštita Sukladno reakciji oksidacije uz sudjelovanje kisika, potiče razmnožavanje mikroorganizama i bakterija što dovodi do kvarenja i kvarenja hrane.Dušik je inertni plin koji može ugušiti i spriječiti razmnožavanje bakterija u hrani.Svrha korištenja dušika je eliminacija kisika i usporavanje oksidacije i disanja hrane.Posebno, topljivost dušika je mala u vodi i ulju, a adsorpcija dušika hranom je relativno mala.Stoga se može koristiti kao bolji plin za antiseptik i konzerviranje hrane. Skladište otporno na insekte Punjenje dušikom može spriječiti štetu od štetnika za žitarice, orašaste plodove, voće, povrće itd.U međuvremenu, skladištenje dušika može usporiti metabolizam baš kao i ulazak u stanje hibernacije i inhibiranje naknadnog sazrijevanja, tako da se može pohraniti dulje vrijeme. Zatvaranje (konzerviranje) i skladištenje vina Dušik može ukloniti kisik i spriječiti oksidaciju, kvarenje i promjenu boje gaziranih pića i jestivog ulja za pivo, vino, voćno vino, jestivo ulje, prešanje limenki, puhanje i zatvaranje boca.Ako koristite pluteni čep, može spriječiti pojavu plijesni na čepu u boci. Puhanje dušika Puhanje dušika može povećati volumen i silu ekspanzije kako bi se produžio vijek trajanja prehrambenog ulja, majoneze, margarina u bačvama ili ulja od kikirikija. Identifikatori modela generatora dušika za membransku separaciju. Bilješka: U skladu sa zahtjevima kupca (protok dušika / čistoća / tlak, okoliš, glavne upotrebe i posebni zahtjevi), Binuo Mechanics će biti prilagođen za nestandardne proizvode.
