Okutegeeza:

DPG y’emu ku zisinga obukulu mu kutumbula vulcanization za kapiira, nga zino zisinga kukozesebwa mu butonde ne synthetic rubber.Erina obuziyiza obulungi okukaddiwa mu vulcanized rubber ate era ekola nga activator ya thiazole, thiuram ne sulfonamide promoters.Mu chloroprene rubber has the plasticizer, the the plasticizer the function the functions the perduces the raw matermater Auxiliary agent n’ebirala, okusinga akozesa mu manufacture tire ne rubber product n’ebirala ku rubber sole.

Enkola enkulu ez’okukola promoter DPG mulimu cyanide chloride, metal oxide desulfurization ne oxidation desulfurization.Mu byo, catalytic oxygen oxidation ye nkola esinga okutuukira ddala ku green chemistry.

At present, the industrialization methods of rubber vulcanization promoter DPG are using oxygen as oxidant, under the catalysis of copper acetate catalyst, the raw material diphenyl thiourea (CA) ammonia is oxidized to generate the promoter DPG.Specifically, (1) preparation of diphenyl thiourea by first mixing aniline with water and then reacting with carbon disulfide and sulfur;(2) diphenyl thiourea Yatabulwamu amazzi, ammonia yayongerwako, oxygen yayisibwamu, era diphenyl guanidine yafunibwa mu catalytic oxidation reaction.(3) Olwo ekintu kisaanuusibwa mu asidi okusengejja ebiwujjo. Olwo alkali ow’amazzi akozesebwa okutonnya n’okusengejja ekintu. Olwo omunnyo omunene mu kintu ne gunaazibwa n’amazzi amangi.Enkola eno ya kinnansi nnyo. Okusobola okukakasa omuwendo gw’okukyusa CA mu nkola y’okufulumya, okutwalira awamu amazzi ga ammonia agasukkiridde geetaagibwa. Mu nkola y’okufulumya, ggaasi wa ammonia ne okisigyeni byangu okukola omutabula ogw’okubwatuka, oguleeta akabi ak’amaanyi mu by’okwerinda.Mu kiseera kye kimu, okusobola okwanguya sipiidi y’okuddamu, enkola y’okukola yeetaaga okuwa puleesa omuwendo ogugere, okuziyiza puleesa y’ebyuma era kwetaagisa, enkola empanvu-enkola y’ekiseera ey’ekiseera eyeetaagisa eri waggulu, okuteeka ssente mu by’amakolero kunene.

In addition, at present, the synthesis process of promoter DPG mainly adopts kettle type reactor for batch operation, and the batch is greatly affected by personnel operation, so the product quality is prone to instability.At the same time, during the kettle oxidation process, the amount of ammonia feed is large, and the unreacted ammonia and oxygen are easy to form explosive mixture, which increases the process risk.At the same time, the manufacture cost of pressure Reactor eri waggulu, era kyangu okuba n'ebizibu mu nkola empanvu-Term.

Microchannel reactor erina ekitundu ekinene ekigere eky’okungulu, okutabula amangu, okutambuza amaanyi amangi mu kutambuza ebbugumu, embeera z’enkola y’ensengekera era kisikiriza okufaayo kungi okw’abanoonyereza mu kitundu ky’okusengejja eddagala, okutambuza kwayo okw’amaanyi okw’amaanyi, okukola obulungi ebbugumu okufuula enkola nnyingi okusobola okutegeera okufuga okutuufu, n’oluvannyuma endowooza y’enkola ey’akaseera obuseera n’ekola obulungi.

Enkola y’okukola obutasalako eya Vulcanization Accelerator DPG yeetaaga okunoonyereza okulala.
