High kuthamanga reactors Wapadera PTFE liner kwa reactors

High kuthamanga reactors riyakitala liners opangidwa kuchokera PTFE zimatsimikizira mulingo woyenera kukana mankhwala.

Chitetezo cha corrosion chikuphatikizidwa

PTFE liner, yomwe ndi yokhuthala mamilimita angapo, imateteza choyatsira chitsulo chosapanga dzimbiri bwino kuti chisachite dzimbiri, ngakhale kuzinthu zowononga monga ma asidi ndi alkali.PTFE imasiyanitsidwa ndi kukana kwake kwambiri pafupifupi mankhwala onse, zomwe zimapangitsa kuti zitheke popanda ma aloyi ambiri okwera mtengo.Izi zimachepetsa kwambiri ndalama zogulira.

Chiwopsezo cha kuipitsidwa kwapakatikati ndikosavuta kuwongolera ndi PTFE liners.Zopangira zitsulo, monga Pt, Rh, Raney Nickel ndi zina zimamatira kuzitsulo zazitsulo ndipo zimakhala zovuta kuchotsa.M'mayesero otsatirawa funso likupitilirabe ngati zotsatira zake zachitika chifukwa cha kusintha kwa chothandizira, kuwononga kapena kupha poyizoni.Vutoli limathamangitsidwa mwachidwi posungira cholumikizira cha PTFE pamtundu uliwonse wa chothandizira.

Langizo: Zingwe za PTFE zitha kugwiritsidwanso ntchito ngati zotengera zosungirako zoyankhira.

Kugwiritsa ntchito konsekonse

High kuthamanga reactors angagwiritsidwe ntchito pa zolinga zonse;Ziwalo zonse zomwe zimakumana ndi gawo lamadzimadzi zimatetezedwa kuti zisawonongeke ndi mankhwala pogwiritsa ntchito fluoropolymers.Chovalacho chimasindikizidwa bwino ndipo chimamatirira mkati mwa khoma la riyakitala ngati chikopa.Choncho zimasiyana kwambiri ndi PTFE liners, amene anayikidwa lotseguka mu riyakitala.Liner yonseyo imakhala ndi choyikapo chochotseka cha PTFE, chivundikiro, chitoliro choviika ndi ma agitator sheaths ndi mphete zosindikizira za PTFE.Zigawo zonsezi zitha kuchotsedwa ndikuyikidwanso mosavuta kuti ziyeretsedwe.Makulidwe a makoma a liner amatengera voliyumu ya riyakitala ndipo amakhala pakati pa 1.6 ndi 7.4 mm.Kutalika kwa chivundikirocho ndi pafupifupi 3.7 mm.Kuthamanga kwakukulu kwa ma reactors ndi mipiringidzo 200 ndipo kutentha kwakukulu kwa ntchito yosalekeza ndi 230 ° C.Kwa nthawi yochepa (ie max. 60 min) riyakitala imathanso kutenthedwa mpaka 260 °C.Kutentha kwambiri komanso kutentha kwanthawi yayitali kuposa 260 ° C kumawononga PTFE liner.

Chifukwa cha kutentha kwapamwamba kumeneku, zigawo za PTFE zachizolowezi zimakhala "zosokoneza";koma mkulu kuthamanga reactors zigawo satero.Izi zigawo PTFE alibe malangizo ankakonda chifukwa, chifukwa cha isostatic psinjika-akaumba njira opangidwa ndi riyakitala kuthamanga alibe malangizo ankakonda ndi kudzisiyanitsa ndi coefficients kukula chomwecho mbali zonse mu danga."Kusokonekera" kwa ziwalozo, ngakhale pa kutentha kwakukulu ndi kupanikizika kumachotsedwa.

Ubwino wa PTFE-lining:

* Kutentha kwakukulu, pang'ono mpaka +260 °C* Kupanikizika kwambiri mpaka mipiringidzo 200* Kulimbana ndi mankhwala kwachilengedwe chonse, ngakhale ma asidi amphamvu ndi alkali* Yosawononga* Yopanda kuipitsidwa
