1. Kev txhais thiab cov qauv theem pib
PTFE (polytetrafluoroethylene) washer yog ib qho me me, feem ntau feem ntau siv rau kev sib khi, txuas, lossis faib tawm. Nws yog ua los ntawm PTFE, ib qho khoom siv tshuaj fluoropolymer ntawm tetrafluoroethylene.
Tus qauv ntawm PTFE Washer yog yooj yim. Feem ntau nws muaj lub tiaj tiaj, puag ncig nrog lub qhov nruab nrab. Lub thickness tuaj yeem sib txawv raws li cov kev xav tau tshwj xeeb, xws li los ntawm ob peb millimeters rau thanner gauges.
2. Cov khoom ntawm PTFE Washer
* Tshuaj lom neeg Kuj
PTFE muaj npe nrov rau nws cov tshuaj tiv thaiv tshwj xeeb. PTFE washers can withstand a wide range of chemicals, including strong acids (such as hydrochloric acid, sulfuric acid), strong bases (like sodium hydroxide), and various organic solvents (for example, toluene, acetone). Cov cuab yeej no ua rau lawv haum rau kev siv cov khoom siv ua tshuaj lom khoom, qhov chaw uas lawv tuaj yeem tiv thaiv cov dej xau thiab tiv thaiv lwm yam los ntawm kev corrosion.
Lawv kuj tiv taus oxidative tshuaj thiab muaj peev xwm tswj tau lawv txoj kev ncaj ncees txawm nyob hauv cov dej tsis haum ntev ntev.
* Kub Kuj
PTFE wreakers muaj qhov kub zoo heev - muaj peev xwm tiv taus muaj peev xwm. Lawv tuaj yeem ua haujlwm nyob rau hauv qhov chaw kub ntau, los ntawm tsawg tsawg kawg (nqis}}}}}} }ativelyatively relativelyatively highatively້ອງ (txog 260 degree).
Qhov ntsuas ntau qhov no tso cai rau lawv siv hauv cov ntawv thov xws li cov txheej txheem cryogenic thiab qhov siab - kev siv roj - ua cov tshuab muaj kev lag luam ncu.
* Tsawg txhuam coefficient
PTFE muaj ib qho ntawm qhov qis tshaj kev sib txhuam coefficients ntawm cov khoom siv cov khoom. PTFE ntxhua khaub ncaws, vim li ntawd, muab cov chaw du uas txo kev sib txhuam ntawm cov chaw uas lawv tau cais.
Cov cuab yeej no muaj txiaj ntsig zoo hauv cov ntawv thov uas yuav tsum txav lossis tig sib tawm. Piv txwv li, hauv cov cuab yeej siv tshuab xws li bearings thiab cov ntaub ntawv, PTFE lub tshuab ntxhua khaub ncaws tuaj yeem txo cov hnav thiab siv zog vim kev sib txhuam.
* Tsis yog - Cuam Tshuam
Qhov tsis yog - lo tus yam ntxwv ntawm PTFE yog zoo - paub. PTFE Warms yuav tsis ua raws li cov tshuaj feem ntau.
Qhov no ua rau lawv zoo tshaj plaws rau cov ntawv thov uas kev ua kom huv thiab tso tawm yooj yim yog qhov tseem ceeb. Nyob rau hauv cov khoom noj - kev ua khoom noj khoom haus, piv txwv, PTFE lub tshuab ntxhua khaub ncaws tuaj yeem tiv thaiv cov khoom noj kom ua los ntawm cov khoom noj, kom huv si ntawm cov cuab yeej siv.
3. Kev thov
* Kav dej thiab cov yeeb nkab fittings
Hauv cov kav dej kav dej, PTFE cov tshuab ntxhua khaub ncaws feem ntau yog siv los ua cov ntsaws ruaj ruaj pob qij txha pob qij txha. Lawv tuaj yeem tiv thaiv dej lossis lwm cov kua dej los ntawm kev xau ntawm cov kav dej thiab cov fittings. Piv txwv li, hauv cov kais dej los sib dhos, PTFE cov chaw ntxhua khaub ncaws hnav nruab nrab ntawm lub pob valve thiab lub cev kom ntseeg tau tias ib lub foob thiab cov tshuaj tivthaiv ntawm cov kais dej.
Nyob rau hauv cov roj piping roj, lawv kuj tseem tuaj yeem siv rau kaw kev sib txuas thiab kev tiv thaiv roj, muab cov kev ntseeg siab thiab ntev - ntev tshaj plaws txawm tias nyob rau hauv kev ntsuas sib txawv.
* Kev Lag Luam Automotive
PTFE lub tshuab ntxhua khaub ncaws tau siv nyob rau hauv ntau lub cav tsheb. Nyob rau hauv lub cav compartment, lawv tuaj yeem pom nyob hauv cov tshuab roj, qhov chaw uas lawv pab ntim cov roj kab thiab tiv thaiv cov roj to.
Lawv kuj tau siv nyob rau hauv lub system braking. Piv txwv li, hauv qee cov kev sib tham nres, PTFE Farvers tau siv los muab txoj kev ua kom du thiab txhim khu kev ua haujlwm ntawm tus brake thiab txo txoj kev pheej hmoo ntawm cov dej xau.
* Cov Khoom Siv Hluav Taws Xob
Nyob rau hauv cov phiajcawv hluav taws xob thiab cov txuas, PTFE lub tshuab ntxhua tuaj yeem ua raws li cov ntsaws ruaj ruaj. Lawv tiv thaiv lub ingress ntawm ya raws thiab hmoov av, uas yuav muaj qee yam ua rau hluav taws xob luv - circuits lossis kev puas tsuaj rau cov hluav taws xob sib txawv.
Lawv cov tshuaj kuj tseem ua rau lawv siv tau rau hauv cov cuab yeej uas yuav raug rau cov tshuaj uas xeb hauv kev lag luam lossis sab nraum zoov hluav taws xob.
4. Kev tsim kho cov txheej txheem
PTFE cov tshuab ntxhua khaub ncaws feem ntau yog tsim los ntawm cov txheej txheem xws li compression moulding lossis machining.
COMPRESSION MOADING
Hauv kev molding molding, PTFE hmoov yog muab tso rau hauv cov pwm kab noj hniav nrog cov duab uas xav tau ntawm lub tshuab ntxhua khaub ncaws (suav nrog lub hauv paus). Cov pwm yog tom qab ntawd raug rau kev kub siab thiab kub. Lub siab yuam kom cov hmoov kom yoog raws li cov pwm ntawm cov pwm, thiab cov cua sov ua rau lub PTFE rau sinter thiab ua ib lub tshuab ntxhua khaub ncaws.
Tus txheej txheem no tso cai rau kev tsim cov tshuab ntxhua khaub ncaws nrog cov khoom sib txawv thiab cov khoom, thiab nws haum rau huab hwm coj - kev tsim khoom.
Ntaub
Machining koom nrog kev coj ua ntej - Tsim PTFE thaiv lossis pas nrig thiab siv cov txuj ci xws li tig, lossis drilling los ua nws rau hauv lub tshuab ntxhua khaub ncaws. Hom no yog qhov tsim nyog rau kev cai - ua lossis me me - kev tsim khoom me me, qhov twg pom tseeb qhov ntev thiab cov duab geometries thiab tshwj xeeb. Txawm li cas los xij, nws tuaj yeem yog sijhawm ntau dua - siv thiab them tus nqi ntxiv rau compression moulding rau loj moulding rau loj - teev ntau lawm.
