Ubushushu obuphezulu & ukunxiba i-oyile ye-PTFE enganyangekiyo
Izinto eziluncedo PTFE oli itywina
1. Ukuzinza kweekhemikhali: phantse yonke imichiza yokumelana neekhemikhali, i-asidi eqinile, isiseko esinamandla okanye i-oxidant enamandla kunye ne-solvents ye-organic ayichaphazeleki.
2. Ukuzinza kwe-Thermal: ubushushu obuqhekezayo bungaphezulu kwe-400 ℃, ngoko inokusebenza ngokuqhelekileyo kuluhlu lwe -200℃350 ℃.
I-3 yokumelana nokunxiba: I-PTFE i-coefficient ye-friction coefficient iphantsi, kuphela i-0.02, yi-1/40 yerabha.
4. Self-lubrication: PTFE imathiriyeli inomsebenzi ogqwesileyo self-lubrication, phantse zonke izinto viscous ayikwazi ukubambelela kumphezulu.
Zeziphi iingenelo ze-PTFE olitywina xa kuthelekiswa nerubha yetywina eqhelekileyo?
1. Ptfe ioli itywina yenzelwe ngamandla emilebe ebanzi ngaphandle kwentwasahlobo, enokusebenza ngokuqhelekileyo phantsi kweemeko ezininzi zokusebenza;
2. Xa i-shaft ijikeleza, ivelisa ngokuzenzekelayo i-thrust yangaphakathi (uxinzelelo luphezulu kune-oyile yerubha eqhelekileyo), enokuthintela ukuhamba kolwelo;
3. Itywina le-oyile ye-Ptfe inokulungela i-oyile okanye indawo yokusebenza kwe-oyile encinci, iimpawu eziphantsi zokukhuhlana emva kokuvalwa, xa kuthelekiswa ne-oyile yerubha eqhelekileyo isetyenziswa kakhulu;
4. Iitywina zePtfe zinokutywina amanzi, iasidi, ialkali, isinyibilikisi, igesi, njl.;
5.PTFE ioli itywina ingasetyenziswa kwiqondo lobushushu eliphezulu 350℃;
6. i-PTFE oil seal inokumelana noxinzelelo oluphezulu, inokufikelela kwi-0.6 ~ 2MPa, kwaye inokumelana nobushushu obuphezulu kunye nesantya esiphezulu.
Iworkshop
Isicelo
abembi, iinjini, izixhobo zoomatshini bobunjineli, iimpompo zokufunxa, izando zokutyumza, izixhobo zonyango lweekhemikhali kunye neengcali ezahlukeneyo, izixhobo zilungele ngokukodwa i-oyile yerubha yemveli ayinakuhlangabezana nesicelo.
