Li-reactor tsa khatello e phahameng e ikhethang ea PTFE liner bakeng sa li-reactor

Li-reactors tse matla tsa khatello e phahameng li-reactor liner tse entsoeng ka PTFE li tiisa ho hanyetsa lik'hemik'hale ka ho feletseng.

Tšireletso ea kutu e kenyelelitsoe

PTFE liner, e botenya ba limilimithara tse 'maloa, e sireletsa mochini o matla oa tšepe e sa hloekang hantle khahlanong le ho bola, esita le khahlano le mecha ea litaba e senyang joalo ka asiti le alkali.PTFE e khetholloa ka khanyetso ea eona e babatsehang hoo e batlang e le lik'hemik'hale tsohle, e leng se etsang hore ho khonehe ho etsa ntle le lisebelisoa tse ngata tse theko e boima tse khethehileng.Sena se fokotsa haholo litšenyehelo tsa ho reka.

Kotsi ea tšilafalo e ka bang teng ho bonolo ho e laola ka li-liner tsa PTFE.Li-catalyser tsa tšepe, tse kang Pt, Rh, Raney Nickel joalo-joalo li khomarela li-reactor tsa tšepe 'me li thata haholo ho li tlosa.Litekong tse latelang potso e ntse e eketseha haeba litlamorao tse bonoang li hlile li bakoa ke phetoho ea catalyser, litlamorao tsa ts'oaetso kapa chefo ea catalyst.Bothata bona bo qojoa ka bokhabane ka ho boloka lesela la PTFE bakeng sa mofuta o mong le o mong oa catalyser.

Keletso: Li-liner tsa PTFE le tsona li ka sebelisoa e le likepe tsa polokelo tse sebetsang bakeng sa tharollo e sebetsang.

Tšebeliso e akaretsang

Li-reactors tsa khatello e phahameng li ka sebelisoa bakeng sa merero eohle;likarolo tsohle tse kopanang le karolo ea mokelikeli li sirelelitsoe khahlanong le tlhaselo ea lik'hemik'hale ka li-fluoropolymers.Liner e tiisitsoe ka mokhoa oa hermetically 'me e khomarela ka hare ho lebota la reactor joalo ka letlalo.Kahoo e fapane haholo le li-liner tsa PTFE, tse kentsoeng li bulehile ka har'a mochini.Liner kaofela li na le PTFE e kentsoeng, lesela la sekoaelo, phala ea dip le li-agitator sheaths le mehele ea PTFE e tiisang.Likarolo tsena kaofela li ka tlosoa 'me tsa kenngoa hape habonolo molemong oa ho hloekisa.Botenya ba marako a liner bo ipapisitse le molumo oa reactor mme bo pakeng tsa 1.6 le 7.4 mm.Lesela la sekoahelo le bonyane limilimithara tse 3.7.Khatello e phahameng ea ts'ebetso ea li-reactor ke li-bar tse 200 'me mocheso o phahameng oa ts'ebetso e tsoelang pele ke 230 ° C.Ka nako e khuts'oane (ke hore, boholo ba metsotso e 60) reactor e ka futhumatsoa ho fihlela ho 260 °C.Mocheso o phahameng oa mocheso le likhato tse telele tsa ho futhumatsa tse ka holimo ho 260°C li senya liner tsa PTFE.

Ka lebaka la mocheso ona o phahameng oa ts'ebetso, likarolo tse tloaelehileng tsa PTFE li "sotha";empa likarolo tsa li-reactors tse phahameng ha li etse joalo.Likaroloana tsena tsa PTFE ha li na tataiso e ratoang hobane, ka lebaka la mokhoa oa isostatic compression-molding o hlahisoang ke li-reactors tse phahameng tsa khatello ha li na tataiso e khethiloeng 'me li ikhetholla ka li-coefficients tse tšoanang tsa katoloso libakeng tsohle sebakeng."Ho sotha" ha likarolo, esita le mocheso o phahameng le khatello ka hona ha li kenyelletsoe.

Melemo ea PTFE-lining:

* Matla a phahameng a ho kokobetsa, ka nakoana ho fihla ho +260 °C* Ha u hatelle ho fihla ho li-bar tse 200* Ho hanyetsa lik'hemik'hale hohle, esita le ho li-acid tse matla le alkali* Ha e senye* Ha e na tšoaetso.
