I-PTFE Encapsulated O-Rings

Ama-o-rings ahlanganiswe ama-o-ring ahlanganisa i-polymer encapsulation engenamthungo neyunifomu evala ngokuphelele into ewumgogodla werabha.I-Elastomer/rubber core material ukukhetha kweSilicone noma iViton.Inhlanganisela yalezi zingxenye idala i-o-ring ene-inert cishe ngamakhemikhali kanye nesethi yokucindezelwa imelana ukuze isetshenziswe ezindaweni zokuvala ezinzima.Le nhlanganisela yebhantshi le-polymer elikwazi ukumelana namakhemikhali ngaphezu kwesethi ye-elastomer ecindezelwe kancane ihlinzeka ngezakhiwo ezihlukile zohlu lwezinhlelo zokusebenza ezidingekayo.

PTFE Encapsulated o-izindandathoama-o-ring ahlanganisa i-PTFE FEP/PFA encapsulation/jacket engenamthungo futhi efaka ngokuphelele into eyinhloko i-Viton® fluoroelastomer (etholakala futhi nge-silicone).Inhlanganisela yalezi zingxenye idala i-o-ring ene-inert cishe ngamakhemikhali kanye nesethi yokucindezelwa imelana ukuze isetshenziswe ezindaweni zokuvala ezinzima.Ama-o-rings ahlanganisiwe azonciphisa isikhathi sokuphumula futhi ngaleyo ndlela andise inzuzo nomaphi lapho uketshezi olubolayo namagesi kubangela ukuhluleka kokuvala ngaphambi kwesikhathi.

I-PTFE inikeza indawo engeyona induku ukuze kuhlanzwe kalula izinto ze-viscous.Lawa ma-o-ring ane-coefficient ephansi yokungqubuzana okungu-.2 kunsimbi futhi indawo yama-o-rings iyazithambisa.I-PTFE encapsulation yenza ama-o-rings ahlanzeke ngokuqeda ukungcoliswa koketshezi ngama-elastomers.Ama-o-ring awakwazi ukuhlanzwa futhi avuleleke ngokuzenzakalelayo, ayavumelana ne-FDA, ayathobelana ne-USP Class VI, ukuthobela kwe-NSF kutholakalela izinhlelo zokusebenza ezithile.

Ama-o-rings ahlanganisiwe aklanyelwe ngokukhethekile ukubhekana nenkinga yokuvala amakhemikhali anonya kakhulu kanye nezicelo zokushisa ezidlulele.Ama-o-rings ahlanganisiwe ahlanganisa i-elastomeric core eqinile noma engenalutho efakwe ku-PTFE FEP noma i-PFA sheath.I-elastomeric core ingaba irabha ye-fluorocarbon noma i-silicon.Izindandatho eziqinile ezihlanganisiwe zivame ukusetshenziswa ezinhlelweni ezimile.I-Hollow Silicone core encapsulated o-rings ivame ukusetshenziswa ezinhlelweni lapho amandla okuvala aphansi adingeka khona njengezinhlelo zokusebenza eziguquguqukayo.I-o-ring ehlanganisiwe inikeza isisombululo esisebenzayo sezinhlelo zokusebenza eziningi ezinzima.I-PTFE FEP noma i-PFA encapsulation empeleni ithinta uphawu futhi i-elastomeric core iqinisekisa ukucindezelwa okungaguquki kophawu.Umphumela uba ukucindezelwa kokuvala ngokuphelele, okukhuphuka ngomfutho ophakathi.I-o-ring ehlanganisiwe iziphatha njengoketshezi olubonakala kakhulu, noma yikuphi ukucindezela okwenziwa esigxivizweni kudluliselwa kuzo zonke izinhlangothi.Izinga lokushisa eliphezulu lokusebenza le-FEP ngu-205°C (400°F) kanye ne-PFA 260°C (500°F).

Izinzuzo

* Excellent chemical ukumelana*Ububanzi bezinga lokushisa - i-silicone core: -75°F kuya ku-400°F (-60°C kuya ku-205°C) - i-flurocarbon core: 5°F kuya ku-440°F (-15°C kuya ku-205°C) - izicelo ezikhethekile zingenzeka kufika ku-500°F (260°C)*Ubulukhuni sebonke 85° Shore A ± 5 durometer*Amagciwane.*Izingcindezi ezisuka ku-vacuum ziye ku-10000 psi (700 bar, 70 MPa)*Izici zesethi yokuminyanisa okuphansi.*Izakhiwo zokunqanda ukunamathela, indawo enganamathele, i-coefficient ephansi yokungqubuzana*I-FDA iyahambisana*Ayikho imikhawulo ku-diameter yangaphakathi
