Izinto zendandatho ye-pall zihlukaniswe ngendandatho ye-pall yepulasitiki, njenge-PVC/PTFE/PP, indandatho ye-pall yensimbi, njenge-304/316/410/carbon steel kanye nendandatho ye-ceramic pall. Lezi zinto ezintathu eziyinhloko, ngaphandle kwendandatho ye-ceramic pall, zinohlobo olulodwa kuphela, njengezinto zensimbi nezepulasitiki, nazo ezihlukaniswe ngezinto ezahlukene. Izici zezinto ngayinye zihlukile.
Indandatho ye-Ceramic Pall
Izinzuzo: Inokumelana okuhle kakhulu ne-asidi nokushisa, kanye nokushisa kokusetshenziswa okungaphezu kuka-1300 ℃. Ingamelana nokugqwala okuvela kuma-asidi ahlukahlukene angaphili, ama-asidi e-organic, kanye nezinyibilikisi ze-organic ngaphandle kwe-hydrofluoric acid, enokumelana ne-asidi okungu-≤ 99% kanye nokumelana ne-alkali okungu-≤ 85%. Intengo ishibhile, futhi kunezincazelo eziningi ongakhetha kuzo, njenge-φ 16, φ 25, φ 38, φ 50, φ 76, φ 80, φ 100, njll., ezingasetshenziswa ezimweni ezahlukene zokushisa okuphezulu nokuphansi futhi zinezinhlelo zokusebenza eziningi.
Indandatho yepulasitiki ye-pall
Izinzuzo:Isisindo esincane, asibuthakathaka, asimelani nokushisa futhi asimelani namakhemikhali, izindleko zokukhiqiza ezimaphakathi, ama-porosity aphezulu, ukwehla kwengcindezi okuphansi kanye nokuphakama kweyunithi yokudlulisa isisindo, indawo ephezulu yokukhukhula, ukuthintana okwanele kwegesi noketshezi, ukusebenza kahle kokudlulisa isisindo. Izinga lokushisa lokusetshenziswa ezindaweni ezahlukahlukene lingu-60-280 ℃, elisetshenziswa kabanzi ezimbonini ezifana ne-petroleum, amakhemikhali, i-chlor alkali, igesi kanye nokuvikelwa kwemvelo.
Okubi:Ayimelani namazinga okushisa aphezulu, ama-asidi aqinile nama-alkali futhi ithambekele ekushiseni.
Izinto zokwakha nezici ezahlukene:
PP(i-polypropylene): imelana nokushisa kuya ku-100 ° C, intengo ephansi kakhulu, kodwa imelana nokugqwala okubuthakathaka kakhulu.
I-RPP(I-Polypropylene Eqinisiwe): Ngokusekelwe ku-PP, amandla omshini kanye nokumelana nokuguguleka kuthuthukisiwe ngokuguqulwa kokuqinisa, okwenza kube kuhle kakhulu kwizicelo ezidinga amandla aphezulu omshini.
I-PVC(i-polyvinyl chloride): Inokumelana okuhle nokugqwala kwamakhemikhali, kodwa ububanzi bayo bokumelana nokushisa bulinganiselwe.
I-CPVC(I-Chlorinated Polyvinyl Chloride): Ibekezelela izinga lokushisa eliphakeme kune-PP, ivame ukufika cishe ku-110 ° C, futhi inokumelana okuhle nokugqwala kwamakhemikhali.
I-PVDF(i-polyvinylidene fluoride): Ingamelana namazinga okushisa afinyelela ku-150°C futhi inokumelana okuhle kakhulu nokugqwala kwamakhemikhali, okwenza ifaneleke ukusetshenziswa isikhathi eside ezindaweni zezimboni ezinzima.
I-PTFE(I-Polytetrafluoroethylene): Ingamelana namazinga okushisa afinyelela ku-260 ° C futhi okwamanje ingenye yezinto ezimelana nokugqwala kakhulu ezaziwayo, ezifanele kakhulu izinqubo zamakhemikhali ezishisa kakhulu nezigqwala kakhulu.
Indandatho yensimbi ye-pall
Izinzuzo:Udonga oluncane, ukumelana nokushisa nokubanda, ukubhoboka okuphezulu, ukugeleza okuphezulu, ukunciphisa ukucindezela okuphansi, ukumelana okuphansi, umphumela omuhle wokuhlukanisa, impilo ende yenkonzo, futhi ingasebenzisa ngokugcwele amandla emishini. Ifanele imibhoshongo yokucwilisa nge-vacuum, imibhoshongo yokususa igesi nge-carbon dioxide, izinto zokuphatha ezibangela ukungezwani komzimba, ezibola kalula, ezilula ukuzihlanganisa, futhi ezithambekele ekufakweni kwe-carbon, esetshenziswa kabanzi emibhoshongweni epakishwe ezimbonini ezifana namakhemikhali kaphethroli, umanyolo, amakhemikhali, kanye nokuvikelwa kwemvelo.
Okubi:Ayimelani nama-asidi aqinile nama-alkali.
Izinto zokwakha nezici ezahlukene:
Insimbi yekhabhoni:izindleko eziphansi kakhulu, kodwa ukumelana nokugqwala okubuthakathaka kakhulu, kufanelekile kwezinye izimo zokusebenza ezinokumelana nokugqwala okubuthakathaka.
Insimbi engagqwali engu-304:Inokumelana okuhle nokugqwala nokumelana nokushisa, futhi ingasetshenziswa ngokuzinzile ezindizeni ezahlukahlukene zamakhemikhali. Iyinto evame ukusetshenziswa njengendandatho yensimbi.
Insimbi engagqwali engu-316L:Ukumelana nokugqwala kungcono kunensimbi engagqwali engu-304, ikakhulukazi ezindaweni ezinokugqwala okunamandla njengama-ion e-chloride. Insimbi engagqwali engu-316L inokuqukethwe okuphansi kwekhabhoni kanye nokusebenza okungcono kokugqwala, okunganciphisa ngempumelelo izinkinga zokugqwala kwe-intergranular ezingase zenzeke ngesikhathi senqubo yokugqwala.
