PTFE (iav fiber ntau) membrane
Cov khoom siv membrane tuaj yeem faib ua A, B, C, D thiab E raws li nws lub zog, qhov hnyav thiab tuab.Cov qauv tsim yuav tsum yog raws li cov qauv kev coj tus kheej ntawm cov qib sib txawv ntawm cov khoom siv membrane.
Cov khoom tseem ceeb ntawm cov txheej yuav tsum yog polytetrafluoroethylene resin, cov ntsiab lus yuav tsum tsis pub tsawg tshaj 90%, thiab qhov hnyav ntawm txheej yuav tsum siab tshaj 400g / m.Lub thickness ntawm PTFE membrane yuav tsum siab tshaj 0.5 hli.
Muaj peev xwm tiv thaiv cov tshuaj corrosion thiab UV yaig, tsis yooj yim rau kev laus, hauv nag nrog kev ua haujlwm ntawm tus kheej.
1. Hauv Tebchaws Europe, Tebchaws Meskas, Nyiv thiab lwm lub tebchaws, PTFE membrane yog cais raws li A2 quasi-tsis-combustible khoom.PTFE membrane nyob rau hauv qhov hluav taws kub ib puag ncig ntawm ntau tshaj 250 ℃, yuav tso tawm cov pa roj, Ministry of Public Security hluav taws kev tshawb fawb lub koom haum tshawb pom, raws li GB8624 "tsev cov ntaub ntawv combustion kev ua tau zoo kev faib tawm txoj kev" yog cais raws li B1 refractory khoom.
2. Lub sijhawm lav zoo ntawm lub cev thiab cov khoom siv tshuaj lom neeg ntawm daim nyias nyias ntawm cov chaw tsim khoom yog 10 xyoo.Txawm li cas los xij, cov khoom siv kho tshuab thiab physicochemical ntawm PTFE daim nyias nyias tsis tau deteriorated tom qab ntau tshaj 20 xyoo ntawm kev ntsuas huab cua.
Kev sib piv ntawm qee yam khoom ntawm ETFE, PVC thiab PTEF cov ntaub ntawv zaj duab xis.
1. ETFE daim nyias nyias yog ib zaj duab xis polyester uas tsis muaj ntaub, tsuas yog ua los ntawm cov pa roj yog txhaj rau hauv lub siab gas los tsim cov qauv bearing cov tswv cuab.
2. PVC daim nyias nyias thiab PTFE daim nyias nyias yog cov khoom siv sib xyaw ua ke, lawv lub hauv paus yog tsim los ntawm cov ntaub fiber ntau, yog li nws muaj peev xwm nkag siab zoo, tuaj yeem siv los ua cov khoom siv.
3. Kev sib piv ntawm qee cov khoom thiab cov nqi siv ntawm ETFE membrane thiab PVC thiab PTFE, ob qho tib si siv ntaub membrane, yog qhia hauv cov lus hauv qab no.
| Lub teeb nyhav | Nws hnyav ib feem ntawm cov khoom siv hauv tsev |
| Siab zog | Cov iav fiber ntau yog cov ntaub ntawv muaj zog tshaj plaws, nws tseem muaj zog dua li tib txoj kab uas hla ntawm cov hlau hlau |
| yooj | Tsis zoo li feem ntau cov khoom siv hauv tsev, cov khoom tuaj yeem ncav cuag ntau yam dynamic arc duab |
| kev xa tawm | Lub teeb sib kis ntawm lub teeb los ntawm qhov chaw sab hauv thiab sab nrauv ua rau muaj qhov muag muag ntawm lub teeb |
| Kev saib xyuas tsawg dua | Kev tu me me yuav tsum tau ua thaum lub neej ntawm cov ntaub.Vim tias qhov saum npoo ntawm cov ntaub yog tsis nplaum thiab tawv, cov nag ntxuav tawm cov plua plav |
| Nto inertization | Ib puag ncig hnyav, xws li pwm, kua qaub los nag, thiab lwm yam, yuav tsis ua haujlwm rau ntawm daim ntaub |
| weldability | Txhua lub thav duab yuav raug welded ua ke los tsim ib lub ru tsev.Lub weld yuav muaj zog dua li ntaub nws tus kheej |
| Lub neej ntev | PTFE coated iav weaves qhia me ntsis degradation nyob rau hauv lawv lub neej thiab kwv yees yuav kav ntev li 25 xyoo. |
| Hluav taws kub tsis kam | Nws muaj A Qib A ntsuas hluav taws, thaum tseem tswj tau lub teeb kis tau zoo |
