FKM sedem papilio valvae

FKM Sedem Papflfly valvae in Industrial-gradus valvae vestibulum systems, fluorocarbon elastomer (designatur fkm secundum ASTM d1418) facta est in malleing engineering materiam ad dynamic signations interfaces debitum ad unique mulgering. Hoc Polymer maintains ASTM D2000 m6ee907 certification pro chemical inertness intra operantes temperatus range of -18 ° C ad CL ° C (per FKM sedem PAPILL CYMBALON).

Core commoda fkm materiae

I. fluoroelatomer (FKM) est fluorine, quibus synthetica elastomer quod adhibetur ut a sede materia ad FKM sedem papilio valvae et proprietatibus includit:

II. Chemical resistentia, fortis acida (ut XCVIII% sulphuric acidum, XXXVII% hydrochloric acidum), fortis alkalis (L% Naoh), Hydrocarbon solvents et ozone et corrosio resistentia level melius quam NBR / EPDM

3. High temperature adaptability: continuous working temperature range -20°C~180°C, short-term resistance to 200°C thermal shock (This is only for pure rubber, when used for butterfly valve seats are usually the maximum temperature is 150°);

IV. Minimum permeability, in Gas permeability non solum 1/5 of NBR, quod prohibet expansionem et defectum de valvae sedem per medium penetrationem;

V. Mechanica stabilitatem: Durange range LXX ~ XC litus a, compressione paro rate≤15% (ASTM D395 test).

VI. Et sedem vitae FKM sedem papilio valvae potest pervenire VIII ~ XII annis, quod est plus quam III temporibus, quod Ordinarius Flexilis valvae sedes

Typical application missionibus:

I. Organic Solvents: Acetone, Xylene, Carbon Tetrachloride, Oxidizing Medium: Hydrogenii Pouroxide (concentration ≤30%), sodium hypochlorite solution

II. Highly mordax fluidorum: electroplating solution, mixta acidum (Aqua Regia), infectum CHLORUM Gas in CHLOR, alkali processus
