Umbhobho we-teflon woxinzelelo oluphezulu unokumelana nobushushu obuphezulu?

I-hose ye-teflon ephezulu yoxinzelelo inokumelana nobushushu obuphezulu, zingaphi iidigri, ngokukodwa kuxhomekeke kwiimpawu zayo eziphathekayo, ubukhulu, ukusetyenziswa kokusingqongileyo kunye nonyango olunokwenzeka lomhlaba kunye nezinye izinto.

Uluhlu lokumelana nobushushu obuphezulu

1. Umda ngokubanzi:

Ngokuqhelekileyo, i-hose ye-teflon ephezulu yoxinzelelo inokumelana nobushushu obuphezulu obumalunga nama-260 degrees.

Ngaphantsi kwemeko yokushisa okuphezulu ngokukhawuleza, ukushisa kwayo kokunyamezela kunokufikelela kuma-degrees angama-400.

2. Iimeko ezikhethekileyo

Kwezinye iimeko ezikhethekileyo, ezifana noxinzelelo oluphantsi kunye nesantya esisezantsi sokuhamba kwegesi, ukuxhathisa ubushushu boxinzelelo oluphezulu lwe-teflon hose kunokuba phezulu, ukuya kuma-300 ° C.

Iimpawu zezinto eziphathekayo

I-high-pressure teflon hoses yenziwe ngokuyinhloko kwizinto ze-polytetrafluoroethylene (PTFE), ezinokumelana nokushisa okukhulu. I-PTFE izinzile ngokwekhemikhali, iyakwazi ukunyamezela zonke iiasidi ezomeleleyo (kubandakanywa ne-aqua regia), i-oxidants ezomeleleyo, ii-agent zokunciphisa kunye nezinyibilikisi ezahlukeneyo zezinto eziphilayo ngaphandle kweentsimbi zealkali ezinyibilikisiweyo, i-media media kunye ne-sodium hydroxide ngaphezu kwe-300 ° C. I-hose ye-teflon yoxinzelelo oluphezulu nayo ineempawu yokumelana nokugqoka kunye nokuzicoca, i-coefficient ephantsi ye-friction, eyenza ukuba kwiindawo ezahlukeneyo eziyinkimbinkimbi inokugcina imeko yokusebenza ezinzileyo.

Iimeko zesicelo

I-hose ye-teflon ephezulu yoxinzelelo isetyenziswa kakhulu kwishishini lekhemikhali, kwikhemesti, ekusetyenzweni kokutya kunye namanye amashishini ngenxa yobushushu bayo obuphezulu, ubushushu obuphantsi kunye nokumelana nokubola kweekhemikhali. Kwishishini lemichiza, inokuthutha ngokufanelekileyo zonke iintlobo zeekhemikhali; kwishishini lamachiza, linokuqinisekisa indawo yezothutho ecocekileyo neyinyumba; kwindawo yokulungisa ukutya, inokuqinisekisa ukhuseleko lokutya kunye nococeko.

Iingongoma ekufuneka uziqaphele

1. Ukwandiswa kwe-thermal kunye nokunciphisa: nangona i-hose ye-teflon ephezulu yoxinzelelo inokumelana nokushisa okuphantsi ukuya kwi--190 degrees, kodwa ukusetyenziswa kobushushu obuphantsi kakhulu, imfuneko yokuqwalasela ukwandiswa kwe-thermal kunye nokunciphisa ukusebenza kwe-hose. Ngokuqhelekileyo umda okhuselekileyo kunye osebenzayo wokusetyenziswa kobushushu ucetyiswa malunga ne-70 degrees.

2. Umda woxinzelelo: ngaphezu kokumelana nokushisa okuphezulu, i-hose ye-teflon ephezulu iyakwazi ukumelana noxinzelelo oluphezulu (njengokungathi malunga ne-bar ye-100) , kodwa kwizicelo ezisebenzayo kufuneka zikhethe iinkcukacha ezifanelekileyo ze-hose kunye neemodeli ngokwemiqathango ethile.

I-hose ye-teflon ephezulu yoxinzelelo phantsi kweemeko eziqhelekileyo ukumelana nobushushu obuphezulu obuqhubekayo malunga nama-degrees angama-260, iqondo lokushisa elikhawulezayo linokufikelela kuma-400 degrees. Ngaphantsi kweemeko ezithile, ukuchasana kweqondo lokushisa kunokuba phezulu. Nangona kunjalo, ekusetyenzisweni kwesidingo sokuthobela ingqalelo yokwandiswa kwe-thermal kunye nokunciphisa impembelelo yokunyanzeliswa kwengcinezelo kunye nezinye izinto.
