Selective Laser Sintering - Sls Stereo Light Curing Molding - Sla
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.

Iran’s Deputy Minister of Petroleum Salim Salim stated that Iran has signed cooperation agreements with petrochemical projects in five countries including Russia, Turkey, South Africa, India, and Oman, mainly involving production technologies and equipment for products such as urea, ammonia, polyethylene, and methanol. , and plant construction and so on. He also stated that as of the end of this year, Iran’s investment in petrochemical industry projects will reach US$3.3 billion.
