PFA (DS702&DS701&DS700&DS708)
PFA ndi copolymer ya TFE ndi PPVE, yokhala ndi kukhazikika kwamphamvu kwamankhwala, katundu wotsekereza magetsi, kukana zaka komanso kukangana pang'ono.Makina ake okwera kutentha ndi apamwamba kwambiri kuposa PTFE, ndipo amatha kusinthidwa ngati ma thermoplastics wamba ndi extrusion, kuwomba, jekeseni. akamaumba ndi zina zonse thermoplastic processing luso.

Kugwiritsa ntchito
DS702: ntchito akalowa chitoliro, valavu, mpope ndi kubala;
DS70l: ntchito chitoliro, kutchinjiriza jekete ya waya, nembanemba;
DS700: ndondomeko extrusion, makamaka ntchito zamphepo wa waya ndi chingwe;
DS708: ntchito mkulu-liwiro extruded waya ndi chingwe.
Chidwi
Kutentha kwa ndondomeko sikuyenera kupitirira 425 ℃, kuteteza PFA kuwonongeka ndi zida zowonongeka.Musati mukhale nthawi yayitali kutentha kwakukulu.
Phukusi, Mayendedwe ndi Kusungirako
1.Packing: mu thumba pulasitiki nsalu ndi mkati polyethylene thumba ukonde 25kg;
2.Kusungidwa pamalo aukhondo, ozizira ndi owuma, kupewa kuipitsidwa ndi fumbi ndi chinyezi;
3.Zopanda poizoni, zosapsa, zosapsa, zopanda dzimbiri, zonyamulidwa ngati zinthu zopanda ngozi.
