Fume hoods yog cov cuab yeej tseem ceeb ntawm kev nyab xeeb hauv chav kuaj. Nruab nrog lub siab tsis zoo tso tawm, lawv muaj cov pa phem, plua plav thiab tshuaj vapors los tiv thaiv cov neeg ua haujlwm hauv chav kuaj. Lawv tau muab faib ua tshuaj fume hoods, biosafety txee, ductless fume hoods thiab lwm yam raws li daim ntawv thov scenarios. Lawv qhov kev ua tau zoo feem ntau yog nyob ntawm kev xaiv cov khoom siv thiab cov qauv tsim.
Txee Material Analysis & Sib piv
PP Yas (Kev Pabcuam Lub Neej: 8-10 xyoo)
Qhov zoo: Resistant rau cov kua qaub thiab alkalis; weldable thiab kho tau.Qhov tsis zoo: Tsis zoo siab -kub tsis kam (＜80 degree); nquag mus khawb.Daim ntawv thov Scenario: Kev ntub dej chemistry thiab hydrofluoric acid ua haujlwm.
304 Stainless Hlau (Kev Pabcuam Lub Neej: 10-12 xyoos)
Qhov zoo: Cov tshuaj tua kab mob-resistant, yooj yim los ntxuav, siab load-cov kabmob muaj peev xwm.Qhov tsis zoo: Tsis tiv taus hydrochloric acid; tus nqi siab.Daim ntawv thov Scenario: Cov chaw sim tshuaj lom neeg thiab thaj chaw huv.
316 Stainless Hlau (Kev Pabcuam Lub Neej: 12-15 xyoos)
Qhov zoo: Resistant chloride corrosion (xws li, marine ib puag ncig).Qhov tsis zoo: Tus nqi hwm.Daim ntawv thov Scenario: Marine biology thiab siab -kev sim salinity.
Txhua yam -Steel (Epoxy Coated) (Kev Pabcuam Lub Neej: 2–3 xyoos)
Qhov zoo: Tus nqi- ua haujlwm tau zoo thiab hloov tau.Qhov tsis zoo: Txheej txheej txheej nyob rau hauv cov kua qaub muaj zog (1.5-2.5 xyoo).Daim ntawv thov Scenario: Kev qhia chav kuaj thiab qhov chaw tsis muaj zog corrosive.
Cov ntsiab lus tseem ceeb sib piv
Countertop: Ceramic / epoxy resin outperforms lub cev thiab tshuaj board nyob rau hauv kub tsis kam.
Saib Qhov rai: 5 hli tawg- pov thawj tempered iav (tiv thaiv - tawg thiab tiv thaiv- txaws).
Ntxuam: Fiberglass reinforced yas ntxuam (corrosion kuj + tsis tshua muaj suab nrov ＜60dB).

Cov lus pom zoo xaiv cov khoom
Strong Acid & Alkali Ib puag ncig (xws li nitric acid, hydrofluoric acid)
Qhov tseem ceeb yuav tsum tau muab rau cov khoom siv PP welded kom tsis txhob xeb ntawm cov hlau.Piv txwv: Electroplating Laboratories nruab nrog PP fume hoods thiab ob chav -txheej txheej txheej - pov thawj tais.
Cov chav huv huv huv
Txais 304 stainless hlau nrog seamless nto polishing (Ra tsawg dua los yog sib npaug rau 0.5μm) los tiv thaiv kab mob loj hlob.
Cov peev nyiaj tsawg & Corrosion tsis muaj zog
Tag nrho - steel txee nrog epoxy countertop; zam corrosive reagents xws li hydrochloric acid.
Cov av noo siab
Cov txee ntoo yog txwv tsis pub (tus nqi nthuav dav ＞ 0.3%); hloov nrog PP lossis stainless hlau cov ntaub ntawv.
Piv txwv: PCR Laboratory: Stainless hlau fume hoods rau thaj chaw nucleic acid extraction.
