Ukusabela kwamakhemikhali, okwenzeka ngenxa yokushisa okuphezulu nezidingo zokucindezela ezisukela kumabha angu-260 °C / 200, izinhlelo zokusebenza eziklanyelwe zona ama-reactor e-Berghof.Isici esikhethekile samareactor e-Berghof ulayini wabo we-PTFE ohlukile, owugqinsi.Zonke izingxenye, ezihlangana ne-liquid media, zenziwe ngokuphelele nge-PTFE noma zimbozwe nge-fluoropolymer.
Ukuvikelwa kokugqwala kufakiwe
I-PTFE liner, enogqinsi ngamamilimitha ambalwa, ivikela i-reactor yensimbi engagqwali ngempumelelo ekugqwaleni, ngisho nakumamidiya egqwalayo njengama-asidi ne-alkali.I-PTFE ihlukaniswa ngokumelana kwayo okuhle kakhulu nawo wonke amakhemikhali, okwenza kube nokwenzeka ukwenza ngaphandle kwama-alloys akhethekile abizayo, njenge-hastelloy.Lokhu kunciphisa kakhulu izindleko zokuthola.Ubungozi bokungcoliseka okungaba khona kulula ukubulawula ngamalayini we-PTFE.Ama-catalyser ensimbi , njenge-Pt, i-Rh, i-Raney Nickel njll anamathela kuma-reactors ensimbi futhi kunzima kakhulu ukuwasusa.Ezivivinyweni ezilandelayo umbuzo uqhubeka ukhula uma imiphumela ebonwayo ibangelwa ukushintsha kwe-catalyser, imiphumela yokungcoliswa noma ubuthi be-catalyst.Le nkinga igwenywa kahle ngokugcina umugqa we-PTFE wohlobo ngalunye lwe-catalyser.Ithiphu: Amalayini e-PTFE angasetshenziswa futhi njengemikhumbi yokugcina izinto ezisombululo ezisebenzayo.
Ukusetshenziswa kwendawo yonke
Ama-reactors e-Berghof angasetshenziselwa zonke izinhloso;zonke izingxenye ezihlangana nesigaba soketshezi zivikelwe ekuhlaselweni kwamakhemikhali kusetshenziswa ama-fluoropolymers.I-liner ivalwe nge-hermetically futhi inamathela ngaphakathi kodonga lwe-reactor njengesikhumba.Ngakho-ke ihluke kakhulu kumalayini we-PTFE, abekwe avuleke ku-reactor.Wonke ulayini uhlanganisa okokufaka kwe-PTFE ekhiphekayo, ulwelwesi lwekhava, ipayipi lokucwilisa kanye nama-agitator sheaths namaringi okuvala e-PTFE.Zonke lezi zingxenye zingasuswa futhi zifakwe kabusha kalula ngezinhloso zokuhlanza.Ubukhulu bezindonga ze-liner buncike kumthamo we-reactor futhi buphakathi kuka-1.6 no-7.4 mm.Ulwelwesi lwekhava okungenani luwugqinsi oluyi-3.7 mm.Ingcindezi yokusebenza ephezulu yama-reactors ngamabha angama-200 futhi izinga lokushisa eliphakeme lokusebenza okuqhubekayo ngu-230 ° C.Isikhathi esifushane (okungukuthi umkhawulo emizuzwini engama-60) i-reactor nayo ingashisisa kufika ku-260 °C.Izinga lokushisa eliphezulu nezigaba zokushisisa ezinde ngaphezu kuka-260°C zonakalisa ulayini we-PTFE.Ngenxa yalawa mazinga okushisa aphezulu okusebenza, izingxenye ezivamile ze-PTFE “ziyahlanekezelwa”;kodwa izingxenye zeBerghof azikwenzi.Lezi zingxenye ze-PTFE azinakho ukuqondiswa okuncanyelwayo ngoba, ngenxa yendlela yokubumba i-isostatic compression-molding eyakhiwe yi-Berghof ayinakho inkomba ekhethwayo futhi izihlukanisa ngama-coefficients afanayo wokunweba kuzo zonke izinkomba emkhathini."Ukuhlanekezela" kwezingxenye, ngisho nasezingeni eliphezulu lokushisa nokucindezela akufakiwe.
Izinzuzo ze-PTFE-lining:→Amandla okushisa aphezulu, isikhashana afika ku-+260 °C→I-pressure-tight kufika kuma-bar angama-200→Ukuphikiswa kwawo wonke amakhemikhali, ngisho nama-acids anolaka kanye ne-alkali→Okungagqwali→Ayinakungcola
Ukubunjwa kokucindezela kwe-Isostatic
.B Uma kusetshenziswa izindlela ezijwayelekile zokubumba zokucindezelwa kwe-axis eyodwa, njengomthetho izinto ezisetshenziswayo zicindezelwa zibheke phezulu esikhunjeni ngepulaki yamandla.Akukho ukuminyanisa okuvundlile ngokuwela indlela yokuminyanisa.Ngokuphambene, enqubweni yokubumba i-isostatic compression-molding amandla asetshenziswa ngokulinganayo futhi kanyekanye ukusuka kuzo zonke izikhombisi-ndlela emkhathini ngokusebenzisa i-hydraulic medium futhi iyiminyanise ngokulinganayo.Ngakho-ke ukucindezelwa okuphelele kuyafinyelelwa, okuholela ekuqineni okuncane, ukwakheka okungcono kwendawo kanye namandla amakhulu okushuba namandla okucindezela.Azikho izikhombisi-ndlela ezikhethwayo futhi izakhiwo ze-isotropic ziyagcinwa.Ikakhulukazi amandla okudonsa kanye nokucindezelwa kwezinto kuyahambisana kuzo zonke izinhlangothi emkhathini.
Izinzuzo zekhwalithi ngenxa ye-isostatic compression molding
Izinzuzo zokubunjwa kokucindezela kwe-isostatic zingaboniswa ngokusebenzisa izithombe ze-REM ezikhuliswe ngokufanelekile.Uma ikhuliswe izikhathi ezingu-100 izinhlayiya ze-granulate zezinto zoqobo zisengabonakala ku-PTFE uma ingaphansi kokubunjwa kokuminyanisa kwe-axis eyodwa.Ngokuphambene, i-PTFE ebunjwe ngokucindezelwa yi-isostatically ikhombisa ukwakheka kwendawo engaguquki kakhulu.Icishe ilingane ne-TFM™PTFE ehlanganiswe ne-eksisi eyodwa.Kodwa-ke i-TFM™PTFE eyenziwe nge-isostati-cally compression-molded ifinyelela isakhiwo esihle kakhulu nesibushelelezi.Ngaphezu kwalokho, uma kukhuliswe izikhathi ezingu-2,500, kumaphutha ezinto ezibonakalayo ezibunjwe nge-axis eyodwa ayabonakala, angasenzeki ku-TFM™PTFE ebunjwe nge-isostatically compression-molded.
