Amacandelo okuthwala angafumaneka ekufakeni i-bolting, i-tack-welding, i-welding epheleleyo okanye i-mortar embedment, kwaye uhlobo olufanelekileyo lokuthwala kufuneka lukhethwe ngokwendlela yokufakela.I-PTFE kufuneka ikhuselwe ngokufanelekileyo kwi-weld spatter, isitshizi sepeyinti, i-metal swarf njl, ngexesha lofakelo.
Kuluhlu olubanzi lwezicelo, iibheringi ze-PTFE zeSilayidi ziphezulu kuneepleyiti zokwandisa eziqhelekileyo, iirola kunye nenkxaso yohlobo lwengalo yerocker.Baxhasa iplanti yepetrochemical, oomatshini abanzima, imibhobho, izakhiwo kunye neebhulorho zebhanti;zivumela ukwandiswa, ukufinyela kunye nezinye iintshukumo eziphindaphindayo zaso nasiphi na isakhiwo esishukumayo ngenxa ye-thermal, i-seismic okanye amandla ohlukeneyo.
Iibheringi zezicelo ezinjalo kufuneka zisebenze kwimithwalo ephezulu kunye nezantya eziphantsi, kwaye kuphantsi nje kwezi meko ukuba iipropati zokuzithambisa ze-PTFE ziphezulu.Lo mba, kunye nokungatyibiliki kwentonga kunye neempawu ezichasene nemozulu, sisizathu esisisiseko sokuba kutheni i-PTFE ibonakalise ukuba nempumelelo njengesixhobo esithwala isilayidi.
Iingenelo
1 Ukulula koyilo lokuthwala kunye nokulula kokwenziwa kunye nofakelo kwenza ukuba ixabiso leyunithi lisebenze kakuhle.2 Iindleko zokwakha zinokuncitshiswa ngokuyila ukwandiswa kunoxinzelelo.3 I-Coefficient of friction phezu kwendawo yokuthwala ihlala ihleli, nangaphantsi. eyona meko imbi kakhulu.4 Iibheringi azinakugcinwa simahla – i-PTFE iyazithambisa ngokwendalo, ngelixa amasuntswana okungcola afunxwa kwizinto eziphathekayo.Ukhuseleko olulula kuphela olufunekayo ngokuchasene nokungena okubalulekileyo kokungcola.
Coefficients of Friction
I-coefficient of friction ye-PTFE materials ixhomekeke kwizinto ezininzi eziguquguqukayo, kuquka uxinzelelo, isantya sokutyibilika kunye nobushushu.Izimvo zahlulwe malunga nefuthe lezinye izinto eziguquguqukayo, nangona kuvunyelwene ukuba uxinzelelo oluphezulu kunye nesantya esisezantsi sithanda ukukhuhlana okuphantsi.
I-coefficient ingaphantsi kunayo nayiphi na enye into eyomeleleyo yobunjineli.Kuxelwe ngokwahlukeneyo ukusuka kwi-0.02 ukuya kwi-0.2, kodwa oku kuxhomekeke kulungiselelo lomphezulu kunye nendlela yovavanyo.Itshathi yomthwalo / ingxabano ibonisa umphumo womthwalo.
Ngokubanzi, i-coefficient of friction phakathi kwendawo yokukhwelana kunye ne-PTFE isilayidi esithwala i-pad iya kuba yincinci xa uxinzelelo kwi-PTFE luphezulu (ngokuhambelana nemida eyamkelekileyo yokunyuka), ukuthwala kwenziwa kwi-PTFE engazaliswanga, kwaye ukugqitywa komphezulu wokukhwelana kukhazimliswe kakhulu.
Ukongeza, enye yezona mpawu zibalulekileyo zokukhuhlana kwe-PTFE kukungabikho kwe-'stick-slip', kuba ngokungafaniyo nazo zonke ezinye iibheringi eziqhelekileyo, i-static friction ye-PTFE iyalingana okanye ingaphezulu nje kancinci kune-dynamic friction.
