Feem ntau, fluoroplastic daim hlau tsis tuaj yeem siv yog tias lawv qhov o ntau tshaj li ib qho nyiaj
Mar 20, 2023| Cov ntaub ntawv roj hmab fluorine feem ntau siv tsis tau yog tias qhov o ntawm qib siab tshaj 30 feem pua. Nyob rau hauv rooj plaub uas tsis tshua muaj siab (tshwj xeeb tshaj yog qis dua 0.5MPa) thiab lub tshuab nqus tsev, nws tsim nyog siv cov ntaub qhwv roj hmab. Cov khoom siv roj hmab muaj qhov ntom ntom zoo thiab tsis muaj cua permeability. Piv txwv li, fluorine roj hmab yog haum raws li lub sealing gasket rau lub tshuab nqus tsev twj tso kua mis, thiab lub tshuab nqus tsev nqi tuaj yeem ncav cuag 1.3 × 10-7Pa. Thaum siv lub tshuab nqus tsev vacuum ntawm 10-1 ~ 10-7Pa, nws yuav tsum tau ua tiav los ntawm kev ci thiab nqus. Tus nqi ntawm asbestos roj hmab ntawv yog qis dua li ntawm lwm cov gaskets, thiab nws yooj yim rau siv; Qhov teeb meem loj tshaj plaws yog tias txawm tias roj hmab thiab qee qhov muab ntxiv rau hauv cov khoom siv gasket, nws tseem tsis tuaj yeem ua tiav tag nrho cov kev sib tshuam zoo ntawm qhov pores, thiab muaj qhov me me ntawm infiltration.
