Kodi chitoliro cha Teflon (PTFE) ndi chiyani?

1. Chifukwa chiyani amatchedwa chitoliro cha Teflon (PTFE)? Kodi chitoliro cha Teflon chimatchedwa bwanji?

Chitoliro cha Teflon, chomwe chimadziwikanso kuti PTFE chitoliro, chomwe chimadziwikanso kuti "mfumu ya mapulasitiki", ndi polima yapamwamba yopangidwa ndi tetrafluoroethylene ngati monoma. Waxy woyera, translucent, kutentha kwambiri ndi kuzizira kukana, angagwiritsidwe ntchito kwa nthawi yaitali pa -180 ~ 260ºC. Nkhaniyi ilibe inki kapena zina, ndi asidi zosagwira, alkali zosagwira ndi zosiyanasiyana zosungunulira organic, ndipo pafupifupi insoluble mu zosungunulira zonse. Pa nthawi yomweyo, PTFE ali makhalidwe a mkulu kutentha kukana ndi otsika kwambiri mikangano coefficient, choncho angagwiritsidwe ntchito kondomu, kuupanga abwino ❖ kuyanika chitoliro chosavuta kuyeretsa wa mkati wosanjikiza mipope madzi.

2. Mitundu ya chitoliro cha Teflon

①. Teflon smooth bore chubu imapangidwa ndi utomoni wa 100% PTFE wosasinthidwa ndipo ilibe inki kapena zowonjezera. Ndizoyenera kugwiritsidwa ntchito muzamlengalenga ndi ukadaulo woyendetsa, zamagetsi, zida ndi zotsekera, kupanga mankhwala ndi mankhwala, kukonza chakudya, sayansi ya chilengedwe, sampuli za mpweya, zida zosinthira madzimadzi ndi machitidwe opangira madzi. Mapaipi onse amapezeka mu anti-static (katoni) kapena mitundu yamitundu.

②. Chitoliro cha corrugated cha Teflon chimapangidwa ndi utomoni wa 100% PTFE wosasamalidwa ndipo mulibe pigment kapena zowonjezera. Ili ndi kusinthasintha kwabwino kwambiri komanso kukana kwa torsional, imapereka magwiridwe antchito abwino kwambiri pamapulogalamu omwe amafunikira ma bend radii olimba, kuthekera kwakukulu kogwirira ntchito kapena kukana kuphwanya. Bellows amapezeka ndi flares, flanges, cuffs kapena kuphatikiza angapo wokometsedwa chitoliro njira. Mapaipi onse akupezeka mumitundu ya anti-static (carbon).

③. Makhalidwe a kutentha ndi kukana kwa dzimbiri kwa machubu a Teflon capillary akhala akugwiritsidwa ntchito kwambiri m'mafakitale osagwirizana ndi dzimbiri, monga makampani opanga mankhwala, pickling, electroplating, mankhwala, anodizing ndi mafakitale ena. Machubu a capillary makamaka amakhala ndi kukana kwa dzimbiri, kukana bwino kwa makulitsidwe, kukana kukalamba bwino, kusuntha kwabwino kwa kutentha, kukana pang'ono, kakulidwe kakang'ono, kulemera kopepuka komanso kapangidwe kake.
