Zvishandiso zvePTFE Rod

PTFE RodZvimiro:Kushandisa tembiricha yakafara kwazvo (Celsius kubva -200 madhigirii kusvika +260 madhigirii);Anti-majority chemical substance's corrosiveness, kunze kweimwe fluorides uye alkalinity moltenmetal; Yakanakisa michina zvivakwa, kuchembera kuramba; Yakanakisa murazvo kuramba (Inoenderana neASTM-D635 uye D470 nhanho yekuyedza), mumhepo kuti idzorwe sechinhu chinodzoreredza moto; kutorwa kwemvura……

PTFE-polytetrafluoroethylene yakawanikwa naDr. Roy Plunkett weDuPont Research Laboratory musi waApril 6, 1938. PTFE yepakutanga yakagadziridzwa zvakare neDupont uye yakasunungurwa sechigadzirwa muna 1945.

Chigadzirwa chacho chinopesana nekuora kwemakemikari uye chinogona kubata tembiricha inopfuura 500 ° C. Chimwe chezvinhu zvekutanga zveimba zvePTFE "PTFE coated frying pan".Kunyange zvazvo hari ichishanda zvakanaka, yakasiyana nematanda ePTFE uye mahwendefa atinopa.Inopfapfaidzwa pane inenge yakasviba coating, pure PTFE rods uye masheets muPTFE round bar steam valve package ichena yakajeka mashandisirwo eindasitiri PTFE mapurasitiki tsvimbo mashandisirwo eindasitiri PTFE epurasitiki tsvimbo PTFE gaskets uye chiutsi kurongedza.

Nekuti PTFE ine tembiricha yakanyanya uye makemikari kuramba, inowanzo shandiswa kune mavharuvhu maapplication.Kubva nyore chiutsi / inopisa mvura mavharuvhu kusvika yakakwirira tembiricha, fluid inobata maindasitiri caustic kemikari mavharuvhu.Ichi chinhu chakaita semi-chakaomarara kupurasitiki yakaoma uye inogona kugadzirwa nyore - imwe yeakareruka kushandisa epurasitiki.The PTFE tsvimbo anogona machined kupinda chaizvo pedyo tolerances pamusoro diki dhayamita tsvimbo ane dhayamita pamusoro +.002 “/ — .00”.Kemikari kuramba ndechimwe chezvinhu zvakakosha zvine chekuita nemidziyo.Mune maflakes kana maflakes, PTFE inoshandiswa sechinhu chegasket chekupisa kwakanyanya uye makemikari anodzivirira flanges uye zvisimbiso.
