ʻO PTFE ka pena ʻO O Ring Rohs hiki i ka mea hana sila

Uhi ka o-ring i ka ʻumeʻa kemika o tetrafluorin a me ka lahilahi o ka laholio. Hana ʻia ia i ka lahilahi me kahi uhi ea waho a kūpaʻa ia i ka ʻaneʻane o nā media kemika. (Soluble baseMetal, ke kinoea fluorine mehana kiʻekiʻe a me ka chorine trifluoride (koe wale ʻo CIF3) e hoʻohana nui ʻia i nā pauma a me nā kiwikā, nā mea kūʻai wela, nā paila, nā kānana, nā hopena. nā moku, nā moku kaomi a me nā pipeline ʻo Flange, sila mechanical, compressor gas, nā pono hoʻohemo, a pēlā aku.

Aia he ʻekolu mau ʻano ʻili lika i waho: 1.FEP (polyperfluoroethylene propylene), ke anuanu -20 ℃ ~ 200 ℃, ʻano honua āpau; 2.

2.PTFE mahana kūpaʻa -20 ℃ ~ 260 ℃, kūpaʻa wela kiʻekiʻe;

Aia he ʻano nui ʻelua o ke kāpili o loko:

1. Pālika Silikona (SILCON)

2. Fluororubber (VITON)

ʻO nā mea e like me ka rubber nitrile (NBR), EPDM e hoʻonohonoho pono ʻia.

Ka penaʻana: Teflon FEP (polyperfluoroethylene propylene) -60 ℃… 205 ℃ hiki ke hoʻohana ʻia ma ka 260 ℃ ke kiʻekiʻe wela no kahi manawa pōkole.

Ka pena ʻana: Teflon PFA (soltle polytetrafluoroethylene) -60 ℃… 260 ℃ hiki ke hoʻohana ʻia i ke ana wela o 300 ℃ no kahi manawa pōkole.

ʻO ke kumu o loko: VITON– Fluororubber E-60C Papa (lawe ʻia mai)

ʻO ke kumu o loko: SILICON– SILICON rubber ZZR 765B (lawe ʻia mai)

ʻO ke apo paʻa paʻa paʻa ke koho mua. Hoʻohana ākea ia i ka static a me ka sealing paʻa. Hana ʻia ke anawaena o ka hollow silicone rubber cladding sealing ring

ʻOi aku ka nui, hoʻohana ʻia i ke sila static, kona paʻakikī a me ka compressibility ma mua o ke apo paʻa paʻa paʻa i lalo. 2. Fluororubber (VITON)

ʻO nā mea e like me ka rubber nitrile (NBR), EPDM e hoʻonohonoho pono ʻia.
