Umahluko phakathi kwe-teflon kunye ne-polytetrafluoroothylene

I-PVDF yi-Polyvinylidene Futoridene, ebi kakhulu kune-F4 kunye ne-F46, enokuchasana nobushushu obuphantsi kunye nokunganyangeki kancinci kwexabiso eliphantsi kakhulu kune-F4 kunye ne-F46).

I-PTFE (F4) i-polytetraflumyleyyyyyyyyyyyyychone, enobushushu obulungileyo kunye nokunganyangeki kwendlela yokulungela, kwaye inokumelana nolusu. Umbala umhlophe ngokupheleleyo. Isetyenziselwa imibhobho evaliweyo e-fluorine, iivalves, amatywina, iintonga, njl.

I-Fep (F46) yiPolyperfluorookene proplene, umbala ubala, kwaye ukunganyangeki kwe-corosion yayo kuyafana ne-PTFE. Isetyenziselwa i-pumps-larline-langer okanye iimpompo ze-perfluoroticated. I-PFA Tetraflum-PerfluoAlkoene-I-CompolyGralmer Other Binyl (ekwaziwa ngokuba:

Iipropathi zeekhemikhali ze-pfafeptfe ziyafana, kodwa i-fep inokusetyenziswa kuphela ngaphantsi kwe-200 degrees, kwaye i-ptfe ayikwazi ukuba nenaliti.

I-TEFLon ibizwa ngokuba yi-Polytetraflum ngesiNgesi, ekubhekiswa kuyo njenge Teflon, i-PTFE, F8 Teflon yahlulwe yangu-PTFE, i-PFE, i-PFA, i-ETFE

Iindidi ezininzi ezisisiseko:

Teflon ptfe:

PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260°C, with a maximum service temperature of 290-300°C, extremely low coefficient of friction, good wear resistance and excellent chemical stability.

Teflon fep:

I-Fep (i-fluoreinkince ye-Ethylene Propynene Copolymer) I-Hotts ethambileyo kwaye ihamba iye kwenza ifilimu engagungqiyo ngexesha lokubhaka. Inezinzo ezigqwesileyo zekhemikhali kunye neepropathi ezingalindelekanga. Elonaqondo lobushushu lisebenzisa i-200 ° C

I-TFLOLO pfa:

I-PFA (i-perfluoalkyl) i-dooat engekhoyo, njengoFep, inyibilike kwaye ihambe iye kwifilimu engalunganga ngexesha lokubhaka. Inzuzo ye-PFA kukuba inomqondo ophezulu oqhubekayo osebenzisa i-260 ° C, ingqolowa engqongqo kunye nobunzima, kwaye ilungele izicelo ezinamacala athile kunye nokuchasana nemichiza phantsi kweemeko zobushushu obuphezulu.

THFLOn ETFI:

I-ETPI liyi-copolymer ye-copolyner ye-copolyne kunye neTetrafluororoothee, i-guouropolymer emnyama enza ukuba i-goraura engagungqiyo kunye nokungavisisani kweekhemikhali kunye ne-CARTARORTE ukuya kuthi ga kwi-150 ° C.
