Vim li cas PTFE Cov Khaub Ncaws Kub Kub Hnav maj mam nyob rau hauv kev sib txhuam hnyav?

Raws li cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, Jiangsu Aokai Cov Khoom Tshiab yuav piav qhia vim li cas PTFE-coated iav fiber ntau cov ntaub nthuav tawm txo qis hnav hauv kev sib txhuam hnyav. Nws hnav tsis kam mechanism tsis yog tshwm sim los ntawm ib qho tseem ceeb, tab sis tuaj yeem nkag siab los ntawm cov hauv qab no:

1. Tsis tshua muaj kev sib txhuam coefficient thiab tus kheej-lubricating khoom

Polytetrafluoroethylene (PTFE) muaj ib qho kev sib txhuam qis tshaj plaws ntawm cov khoom siv (dynamic kev sib txhuam coefficient approx. 0.04-0.10).

·  Molecular Structure : Cov saw hlau carbon ntawm PTFE yog nruj nreem qhwv los ntawm fluorine atoms nrog siab thiab uniform electron huab ceev, ua rau tsis muaj zog intermolecular rog, tsim ib 'molecular lubricating txheej'.

·  Interfacial Slip : Thaum lub sij hawm kev sib txhuam, PTFE molecular chains yooj yim ua raws li kev sib txhuam kev taw qhia thiab shear ntawm lub counterface (xws li, hlau los yog lwm yam tawv tawv). Kev sib txhuam feem ntau tshwm sim hauv cov khoom siv lossis hloov zaj duab xis es tsis yog ncaj qha adhesion thiab plowing ntawm lub interface, zoo heev txo kev sib txhuam tsis kam thiab shear stress thiab slowing down tus nqi hnav.

2. Load-Bearing thiab Restraining nyhuv ntawm iav Fiber Npuag Core

PTFE high-temperature daim ntaub yog cov khoom sib xyaw nrog iav fiber ntau li cov substrate thiab PTFE li txheej.

·  Main Load Carrier : Cov iav fiber ntau muab lub zog tensile siab thiab ruaj khov. Nyob rau hauv kev sib txhuam hnyav, iav fiber ntau bears feem ntau ntawm cov load thiab shear quab yuam, tiv thaiv PTFE txheej los ntawm macroscopic tearing lossis yas ntws los ntawm kev ntxhov siab ntau dhau.

·  Kev txwv tsis pub hnav cov khib nyiab : Cov txheej txheem fiber ntau txwv qhov loj ntawm PTFE 'strip coj khib nyiab'. Ntshiab PTFE nyhav tsim cov khib nyiab loj vim muaj cov saw hlau molecular stretching, thaum lub iav fiber ntau faib PTFE rau hauv cov cheeb tsam micro, txwv tsis pub hnav mus rau thaj chaw me me nrog cov khoom zoo. Hnav zoo li 'micro-abrasion' es tsis yog 'macroscopic delamination', ua rau txo qis tus nqi hnav.

3. Kev tiv thaiv kub kub thiab thermal stability

Kev sib txhuam hnyav yog inevitably nrog los ntawm kev sib txhuam thaum tshav kub kub. Qhov zoo ntawm PTFE high-temperature ntaub yog:

·  Wide-Temperature Stability : PTFE tswj kev ua haujlwm ruaj khov ntawm -200 ° C txog 260 ° C. Nws qhov kev sib txhuam coefficient txo qis me ntsis nrog qhov kub thiab txias (nyob rau hauv ib qho chaw), tsis txhob softening, adhesion los yog thermal decomposition tshwm sim los ntawm lub zos kub.

·  Thaum tshav kub kub dissipation ntawm iav Fiber : iav fiber ntau muaj thermal conductivity zoo, pab kom dissipate frictional tshav kub, txo qhov kub ntawm lub zos, thiab tiv thaiv tsis ua hauj lwm ntxov ntawm PTFE vim tshav kub.

4. Chemical Inertia thiab Anti-Adhesion Property

PTFE yog resistant rau yuav luag tag nrho cov tshuaj corrosion. Nyob rau hauv ib puag ncig kev sib txhuam hnyav nrog cov roj nplua nyeem, plua plav lossis cov khoom siv corrosive, nws qhov chaw tsis tshua muaj tshuaj lom neeg hnav (xws li, oxidation lossis corrosion-accelerated hnav). Nws lub zog qis qis ua rau nws nyuaj rau cov khoom siv rau cov khoom txias-weld lossis ua raws li cov substrate, yog li tiv thaiv cov nplaum hnav.
