Kev siv Polytetrafluoroethylene (PTFE)

PTFE muaj ntau yam kev siv hauv kev lag luam thiab kev lag luam marine xws li kev lag luam chemical, roj av, textile, zaub mov, papermaking, tshuaj, electronics thiab machinery vim nws cov khoom tshwj xeeb.

1. Daim ntawv thov kev ua haujlwm tiv thaiv corrosion

Vim qhov tsis xws luag hauv corrosion kuj ntawm roj hmab, iav, hlau alloy thiab lwm yam ntaub ntawv, nws yog ib qho nyuaj rau ua tau raws li qhov hnyav ib puag ncig qhov kub, siab thiab tshuaj nruab nrab coexist, ua rau muaj kev poob loj heev. Cov khoom siv PTFE tau dhau los ua cov khoom siv tseem ceeb hauv cov roj av, tshuaj lom neeg kev lag luam, textile thiab lwm yam lag luam vim nws zoo heev corrosion kuj. Nws cov ntawv thov tshwj xeeb suav nrog: xa cov yeeb nkab ntawm kev xa cov roj corrosive, cov kav dej tso tawm, lub raj xa dej, dov zeb high-pressure roj yeeb nkab, siab thiab qis cov kav dej ntawm aircraft hydraulic siab system thiab txias siab system, distillation ntauwd, tshav kub exchanger, dad, ntauwd. , tank hauv ob sab phlu, dav qhov rooj thiab lwm yam khoom siv tshuaj. Qhov kev ua tau zoo ntawm lub foob muaj qhov sib txhuam ntawm kev sib txhuam thiab tsis muaj viscosity, qhov kub thiab txias ntau thiab zoo elasticity rau kev ua haujlwm thiab kev ua haujlwm ntawm tag nrho cov tshuab thiab cov khoom siv, uas ua rau nws tsim nyog rau kev tsim khoom nrog kev ua haujlwm siab corrosion, siv cov ntsaws ruaj ruaj nrog kub. kub tshaj 100 ° C. Xws li tshuab, tshav kub exchanger, siab siab nkoj, loj txoj kab uas hla, Valve, twj tso kua mis zawj flange foob, iav tshuaj tiv thaiv lauj kaub, dav hlau Falan, loj txoj kab uas hla flange foob, ncej, piston pas nrig, valve qws, menyuam twj tso kua mis, pas nrig foob thiab hais txog. .

2. Daim ntawv thov ntawm kev sib txhuam qis hauv kev thauj khoom

Vim tias qhov kev sib txhuam ntawm qee yam khoom siv tsis haum rau refueling thiab lubrication, piv txwv li, nyob rau hauv lub sijhawm uas cov roj moisturizing yuav yaj los ntawm cov kuab tshuaj thiab ua tsis tiav, los yog daim ntawv ua, khw muag tshuaj, khoom noj khoom haus, khoom siv hauv textile thiab lwm yam kev lag luam yuav tsum tsis txhob lubricating. Roj paug, uas ua rau Filled PTFE cov ntaub ntawv zoo tshaj plaws rau cov khoom siv tshuab tsis muaj roj lubricatoin. Qhov no yog vim qhov sib txhuam coefficient ntawm cov khoom siv no yog qhov qis tshaj ntawm cov ntaub ntawv paub zoo. Nws cov kev siv tshwj xeeb muaj xws li bearings rau cov khoom siv tshuaj, papermaking machinery thiab kev ua liaj ua teb machinery, siv piston tsis ua hauj lwm, tshuab cuab yeej qhia rail thiab rider nplhaib; Dav siv los ua choj, qhov, steel qauv ru tsev truss, loj chemical pipeline, cia tank txhawb slider, raws li zoo raws li choj kev them nyiaj yug thiab choj kev sib hloov, thiab lwm yam.

3. Kev siv hluav taws xob thiab hluav taws xob

Qhov poob qis thiab me me dielectric tas li ntawm PTFE cov khoom ua rau nws enameled xaim rau micro motor, thermocouple, tswj ntaus ntawv, thiab lwm yam. PTFE zaj duab xis yog siv los tsim cov capacitors, xov tooj cua rwb thaiv tsev pads, insulated cables, zoo tagnrho rwb thaiv tsev cov khoom ntawm motors thiab transformers yog kuj yog ib qho ntawm cov khoom siv tsis tseem ceeb rau cov khoom siv hluav taws xob xws li aerospace. Kev siv cov yeeb yaj kiab fluoroplastic muaj cov pa oxygen permeability thiab cov dej vapor permeability tsawg, nws tuaj yeem tsim cov pa oxygen sensor; Nws tuaj yeem ua rau lub microphones, hais lus, qhov chaw ntawm cov neeg hlau, thiab lwm yam los ntawm kev ua kom zoo dua ntawm qhov sib txawv ntawm qhov tshwm sim ntawm fluoroplastics nyob rau hauv qhov kub thiab txias; Nws tuaj yeem siv nws cov yam ntxwv qis refractive index, optical fiber tuaj yeem tsim.

4. Daim ntawv thov kev kho mob

Nthuav PTFE cov ntaub ntawv yog ntshiab inert, muaj zog heev Biological Adaptability, tsis ua rau rejection ntawm lub cev, tsis muaj physiological kev phiv rau tib neeg lub cev, tuaj yeem tua tau los ntawm txhua txoj kev, thiab muaj cov qauv microporous, yog li ntawd, nws tuaj yeem siv tau. nyob rau hauv ntau yam kev daws teeb meem, suav nrog cov hlab ntsha tsim thiab kho cov khoom rau cov ntaub so ntswg rov tsim dua tshiab thiab phais phais rau cov hlab ntsha, lub plawv, kev phais dav dav thiab phais yas.

5. Daim ntawv thov ntawm Anti-sticking kev ua tau zoo

PTFE cov khoom muaj qhov tsawg tshaj plaws ntawm qhov nro hauv cov khoom siv, inadhesion ib yam khoom, thiab tseem muaj cov yam ntxwv zoo ntawm kev kub thiab kub tsis kam, yog li ua rau nws siv dav hauv kev tiv thaiv kev tiv thaiv xws li kev tsim cov lauj kaub uas tsis yog-stick. Nws cov txheej txheem los tiv thaiv cov txheej txheem feem ntau suav nrog ob hom: txhim kho PTFE qhov chaw lossis cov ntawv txheeb rau ntawm lub substrate, thiab muab PTFE txheej los yog cov ntaub qhwv nrog iav rau ntawm lub substrate tom qab tshav kub shrinkage.
