Igama:Intambo yokuthunga ye-PTFE
Impahla Elungiselelwe: PTFE
Isisindo: 200g-1000g
Ukucaciswa: 400D-2700D
Umbala:Mhlophe, Mnyama, futhi Ngokwezifiso
Isicelo:Ngokuvamile isetshenziswa kumapayipi, iziqukathi, amaphampu, ama-valve, nezinhlelo ze-radar, imishini yokuxhumana yamafrikhwensi aphezulu, kanye nemishini yomsakazo enezidingo zokusebenza okuphezulu.
Umsebenzi womkhiqizo:Ukuvalwa kwe-Gasket kanye nezinto zokugcoba ezisebenza emithonjeni ehlukahlukene.
1.Ukumelana namakhemikhali:
I-PTFE inokumelana okuphezulu kakhulu nokugqwala kwamakhemikhali, njenge-concentrated sulfuric acid, i-hydrochloric acid, ne-nitric acid.Ngisho noma ibiliswe ku-aqua regia, isisindo sayo kanye nezakhiwo zayo akushintshile, futhi cishe ayincibiliki ezincibilikisini eziningi, inyibilika kancane kuphela kuma-peralkanes (cishe u-0.1g/100g) ngaphezu kuka-300 °C.
2.Ukumelana nesimo sezulu:
I-PTFE ayiwumumbi umswakama, ayishi, futhi izinze ngokwedlulele kumoya-mpilo kanye nemisebe ye-ultraviolet, ngakho inokumelana nesimo sezulu esihle kakhulu.
3.Izakhiwo zikaMechanical:
I-PTFE igcina izakhiwo ezinhle kakhulu zemishini ezingeni lokushisa elibanzi lika -196 kuya ku-260 ° C. Esinye sezici ze-perfluorocarbon polymers ukuthi ayibi brittle emazingeni okushisa aphansi.Ukuminyana kwe-PTFE kukhulu uma kuqhathaniswa, okungu-2.14-2.20g/cm3, awakwazi ukumunca amanzi, futhi izinga lokumunca amanzi elilinganayo lingaphansi kuka-0.01%.
I-PTFE e iyipolymer evamile ethambile futhi ebuthakathaka, ukukhangana phakathi kwama-macro-molecule kuncane, futhi ukuqina, ubulukhuni namandla kuncane, futhi kuzokhubaza ngaphansi kwengcindezi yesikhathi eside.
