Kemikari maitiro, anoitika nekuda kwekushisa kwepamusoro uye kumanikidza zvinodiwa zvinosvika pa260 ° C / 200 mabara, ndiwo mashandisirwo akagadzirirwa maBerghof reactor.Chinhu chakakosha cheBerghof reactors ndiyo yakasarudzika, gobvu PTFE liner.Masevhisi ese, anosangana ne media media, anogona kunge akagadzirwa zvachose kubva kuPTFE kana akaputirwa nefluoropolymer.
Corrosion protection inosanganisirwa
A PTFE liner, iyo yakakora mamillimita akati wandei, inodzivirira simbi isina simbi inonaya zvine mutsindo kubva mukuora, kunyangwe pazvinosvibisa zvinosvibisa zvakaita maasidhi nealkali.PTFE inosiyaniswa nekupikisa kwayo kwakanakisa kunenge ese makemikari, izvo zvinoita kuti zvikwanise kuita pasina akawanda anodhura akakosha alloys, akadai sehastelloy.Izvi zvinoderedza zvakanyanya mari yekutora.Ngozi yekugona kusvibiswa-yakasvibiswa iri nyore kudzora nePTFE liners.Metallic catalysers, senge Pt, Rh, Raney Nickel nezvimwe zvinonamatira kune simbi reactor uye yakaoma kwazvo kubvisa.Muzviedzo zvinotevera mubvunzo unoramba uchikura kana mhedzisiro inocherechedzwa ichinyatso kukonzerwa nekuchinja kwecatalyser, kusvibisa mhedzisiro kana catalyst poisoning.Dambudziko iri rinonzvengeswa zvine mutsindo nekuchengetedza PTFE liner kune yega yega yega catalyser.Tip: Iyo PTFE liners inogona zvakare kushandiswa sezvishandiso zvekuchengetera midziyo ye reactive mhinduro.
Kushandiswa kwese
Berghof reactors inogona kushandiswa kune zvese zvinangwa;zvese zvikamu zvinosangana nechikamu chemvura zvinodzivirirwa pakurwiswa kwemakemikari kuburikidza nefluoropolymers.Iyo liner yakavharwa hermetically uye inonamatira mukati meiyo reactor madziro seganda.Saka inosiyana zvakanyanya kubva kune PTFE liner, iyo inoiswa yakavhurika mukati meiyo reactor.Iyo liner yese inosanganisira inobvisika PTFE yekuisa, yekuvhara lining, dip pombi uye agitator sheaths uye PTFE sealing mhete.Zvose izvi zvikamu zvinogona kubviswa uye kudzorerwa zvakare nyore kuitira kuchenesa zvinangwa.Ukobvu hwemadziro e liner hunoenderana nehuwandu hwe reactor uye hunosvika pakati pe 1.6 ne7.4 mm.Iyo lining yebutiro inokwana 3.7 mm gobvu.Iyo yakanyanya kumanikidza yekushanda yemareactor i200 bars uye tembiricha yepamusoro yekuenderera mberi kwekushanda i230 ° C.Kwenguva pfupi (kureva max. 60 min) reactor inogonawo kudziyisa kusvika 260 °C.Kupisa kwepamusoro-soro uye nhanho dzekudziya dzakareba pamusoro pe260°C zvinokuvadza liner yePTFE.Nekuda kweaya tembiricha akakwira ekushanda, akajairwa PTFE zvikamu zvinova "zvakakanganiswa";asi Berghof zvikamu hazviiti.Izvi zvikamu zvePTFE hazvina kwainoda kutungamira nekuti, nekuda kweiyo isostatic compression-molding nzira yakagadziridzwa neBerghof haina nhungamiro yainoda uye inozvisiyanisa nemakoefifiti mamwe chete ekuwedzera mumativi ese muchadenga."Kukanganiswa" kwezvikamu, kunyange pakushisa kwepamusoro uye kudzvinyirira kunobviswa.
Zvakanakira zvePTFE-lining:→Simba rekupisa, kwenguva pfupi kusvika +260 °C→Pressure-tight kusvika ku200 bars→Universal kuramba kumakemikari, kunyangwe kune aggressive acids uye alkali→Zvisingaori→Kusina kusvibiswa
Isostatic compression molding
.B Kana yakajairwa, imwe-axis compression molding nzira dzinoshandiswa, sekutonga zvinhu zvakatsikirirwa vertically mu mold ine simba plug.Iko hakuna yakachinjika compression crosswise kune iyo compression nzira.Kusiyana neizvi, mune isostatic compression-molding process simba rinoiswa kune izvo zvinhu zvakaenzana uye panguva imwe chete kubva kumativi ese ari muchadenga kuburikidza ne hydraulic medium uye inoimanikidza homogeneous.Saka kudzvanya kwakaringana kunowanikwa, zvichikonzera kushoma porosity, chimiro chiri nani chepamusoro uye yakanyanya kusimba uye yekumanikidza simba.Hapana mafambiro akasarudzika anogadzirwa uye isotropic zvinhu zvivakwa zvinochengetwa.Kunyanya kusimba nekutsikirira kwechinyorwa kunopindirana munzvimbo dzese munzvimbo.
Mabhenefiti emhando yekutenda kune isostatic compression molding
Zvakanakira isostatic compression molding zvinogona kuenzanisirwa nenzira yemifananidzo yakawedzera REM.Kana yakakwidziridzwa ka100 ma granulate particles ezvinyorwa zvepakutanga zvinogona kuramba zvichionekwa muPTFE kana zvakaiswa pasi pe-single-axis compression molding.Kusiyana neizvi, isostatically compression-molded PTFE inoratidza zvakanyanya kuenderana pamusoro pechimiro.Inoda kuenzana ne-single-axis compression-molded TFM™PTFE.Nekudaro isostati-cally compression-yakaumbwa TFM™PTFE inowana yakanyanya kunaka uye yakapfava chimiro.Uyezve, kana yakudzwa 2,500 nguva, mune imwechete-axis compression-yakaumbwa zvinhu zvinokanganisa zvinoonekwa, izvo zvisisaitike mune isostatically compression-yakaumbwa TFM™PTFE.
