FEP ENCAPSULATED O-RINGS / PFA

FEP ENCAPSULATED O-RINGS / PFA

FEP encapsulated O-rings comprise tus tub ntxhais elastomer uas tau raug seamlessly encapsulated hauv lub tsho ntawm Teflon fluoropolymer. Cov tub ntxhais yog Viton, Silicone lossis EPDM. Lub tsho yog FEP lossis PFA.

FEP encapsulated O-rings raug pom zoo thaum tus txheej txheem O-Ring muaj peev xwm ua tsis txaus ua rau daim ntawv thov. Lawv kuj raug pom zoo thaum cov khoom PTFE O-ring tsis muaj lub elasticity rau kev txhim khu kev ruaj ntseg, cov kua dej ntev mus ntev. Cov tshuaj no feem ntau siv rau cov tshuaj ua haujlwm thiab kev tu cev.

Cov lag luam muaj xws li:

• Tshuaj.

• Petrochemical.

• Khoom noj khoom haus.

• Pharmaceutical.

SVKS tuaj yeem siv suab qhov loj ntawm encapsulated rings. Peb tuav ntau ntau thiab tsawg hauv Tshuag. Peb muab cov khoom ua si thiab cov khoob khoob khoob taub hau nrog rau cov xim khwb dub thiab pleev xim.

FEP cross section seem xaivHuaj tub ntxhais txheej txheem (Encapsulated O-Rings) muaj ntau dua compressibility piv rau cov tub ntxhais O-Rings. Tus hollow core yooj txhais txhais tau hais tias tsawg dua clamping quab yuam yuav tsum tau pab kom nws cov sealing peev xwm.

Cov O-rings no zoo tagnrho rau kev siv cov ntaub ntawv tsis zoo, xws li cov iav los yog lub plast plastics, Lawv yog qhov tseem ceeb rau qhov chaw sealing yuav tsum muaj chaw rau kev khiav mus thaum lub sijhawm ua haujlwm.

FEP encapsulated O-rings muaj kev ywjpheej rau ntau hom tshuaj lom neeg. Lawv muab ntau qhov kub raws li:

• -60 ° C rau + 200 ° C nrog Silicone core.

• -20 ° C rau + 200 ° C nrog Viton tseem ceeb.

Lawv muab cov kev sib txhuam thiab tsis tshua muaj 'stick-slip' effect.

PFA encapsulated O-rings muab kev thau ua haujlwm ntxiv. Thaum ua ke nrog Silicone core, lawv muaj ntau yam kub txog -60 ° C rau + 260 ° C.

Peb kuj muab cov PFA encapsulated O-rings nrog Viton core. Cov ntsaws ruaj ruaj tau muab kub kub -20 ° C rau + 200 ° C. Viton core PFA encapsulated O-rings tseem muab ntxiv ua hauj lwm.

Qhov tseeb Teflon FEP / PFA encapsulation ntawm peb cov encapsulated O-rings yog raws li NSF 61 kev cai.

USP CLASS VI

Teflon FEP / PFA fluoropolymers tau soj ntsuam raws li USP Cov Cai. Lawv ua tau raws li cov cai ntawm USP Class VI yas. Tsuas yog cov FEP / PFA encapsulation los ntawm kev sib cuag nrog cov khoom. Peb FEP / PFA encapsulated O-rings raug suav hais tias yog USP Class VI raws txoj cai. Yog xav paub txog peb cov ntaub ntawv tseem ceeb, thov nyeem peb cov ntaub ntawv cov ntaub ntawv.

EU VO 1935/2004 THIAB 10/2011

SVKS Seals tau tshawb nrhiav thiab ntsuam xyuas cov ntaub ntawv BFR. Peb tau them nyiaj tshwj xeeb rau "Cov lus pom zoo ntawm Tsoom Fwv Teb Chaws Lub Chaw Tshawb Fawb Kev Ntsuas Txog Cov Khoom Uas Yuav Tsum Los Sib Pab Nrog Cov Zaub Mov". Txhua yam khoom lossis tsab xov xwm uas tau npaj los rau hauv kev sib cuag, ncaj qha lossis tsis ncaj nraim nrog zaub mov, yuav tsum tau tsim nyog txaus kom tsis txhob muaj cov khoom noj los ntawm cov khoom noj kom loj txaus los tiv thaiv tib neeg kev noj qab haus huv los yog coj tsis zoo hloov ntawm cov zaub mov los yog lub deterioration hauv nws cov khoom organoleptic.

Qhov txheej encapsulate yog FEP los yog PFA yaj txheej txheem tau polymer ntawm PTFE. PTFE tseem muaj lub npe hu ua Teflon hom. PTFE polymers yog qhov siab heev. Feem ntau lawv siv cov zaub mov ua zaub mov thiab cov khoom noj khoom haus hauv tsev ua noj.

Peb zoo siab los tawm tswv yim tias peb FEP / PFA encapsulated O-rings yog raws li EU VO 1935/2004 thiab 10/2011 certification.
