Acrylonitrile bakeng sa PAN
Acrylonitrile bakeng sa PAN,
Acrylonitrile Bakeng sa Polyacrylonitrile, Acrylonitrile bakeng sa fiber ea polyacrylonitrile,
Polyacrylonitrile (PAN) ke polima ea maiketsetso e nang le foromo ea mola (C3H3N)n.Le hoja e le thermoplastic ha e qhibilihe tlas'a maemo a tloaelehileng, kaha e fokotseha pele e qhibiliha ka holimo ho 300 ° C.Hoo e ka bang li-resin tsohle tsa PAN ke li-copolymers tse entsoeng ka motsoako oa li-monomers, 'me acrylonitrile e le eona karolo ea mantlha.Ke polymer e feto-fetohang e sebelisetsoang ho hlahisa mefuta e mengata e mengata ea lihlahisoa, ho kenyelletsa le likhoele tsa masela, li-membrane tsa ultra-filtration, likhoele tse se nang letho bakeng sa reverse osmosis, joalo-joalo.

Sesebelisoa sa Sehlahisoa
Acrylonitrile e hlahisoa khoebong ka propylene ammoxidation, eo ho eona propylene, ammonia, le moea li tšoaroang ke catalyst betheng e nang le metsi.Acrylonitrile e sebelisoa haholo-holo e le co-monomer ha ho etsoa li-acrylic le modacrylic fibers.Litšebeliso li kenyelletsa tlhahiso ea li-plastiki, li-coatings, li-elastomer tsa nitrile, li-resin tse thibelang, le li-adhesives.Hape ke lik'hemik'hale tse lipakeng tsa motsoako oa li-antioxidants tse fapaneng, meriana, lidae le tse sebetsang ka holim'a metsi.
1. Acrylonitrile e entsoeng ka fiber polyacrylonitrile, e leng fiber ea acrylic.
2. Acrylonitrile le butadiene li ka etsoa copolymerized ho hlahisa rabara ea nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ho lokisetsa ABS resin.
4. Acrylonitrile hydrolysis e ka hlahisa acrylamide, acrylic acid le esters ea eona.
