Tetrafluoroethylene ndiro inozivikanwa samambo wemapurasitiki mumunda wemapurasitiki, uye kuita kwayo hakuzadzikiswe nemapurasitiki akajairwa, saka inowanzoshandiswa munzvimbo dzine hutsinye hwakadai seasidhi uye alkali, corrosive media uye kupisa kwakanyanya.Saka, ndezvipi zvakanakira PTFE board?
Kutanga, ine kukwirira kwekushisa kwepamusoro.Nezve kushandiswa kwemazuva ano kwe tetrafluoroethylene sheet zvinhu zvine chekuita, iyo mbishi inogona kusvika 232 ° C, uye kunyangwe tembiricha yakakwira mushure mekudzokera kukeji inogona kusvika kusvika 150 ° C, uye tembiricha yekushandisa yakakura kwazvo.
Iyo PTFE sheet ine yakanakisa dielectric zvivakwa, yakasarudzika dielectric simba uye arc kuramba, yakaderera dielectric kurasikirwa tangent, uye kushomeka kwekona kuramba.Iyo tetrafluoroethylene sheet ine yakanaka isiri-mvura yekunyudza, isina oxygen, UV uye kuramba mamiriro ekunze.Simba rekunze rekusimba rakaramba risina kushanduka kwemakore matatu akatevedzana, kureba chete kwakadzikira.Mafirimu eTeflon uye mabhanhire anopindika kumvura uye gasi nekuda kwekunaka kwavo porosity.PTFE inogona chaizvo kuve yakakodzera kune ambient tembiricha pakati peminus 190 degrees uye 250 degrees.Inogona kupisa kana kutonhora kamwe kamwe, kana kuchinjana kupisa kana kutonhora pasina mhedzisiro.Pamusoro pekugadzirisa matambudziko ekugadzira kemikari uye peturu, tetrafluoroethylene mashizha anogonawo kuita basa mumishonga nemimwe minda.Kune akawanda ekuisa chisimbiso zvikamu pamusika nhasi, pamwe negasket kana gasket zvigadzirwa.Pamusoro pezvo, PTFE inoshandiswawo zvakanyanya mumidziyo ine zvisimbiso zvinodiwa, uye zvakare inowanzoshandiswa seJinxining filler.Basa repepa rePTFE rakakura kwazvo, nokuti pepa rePTFE rine basa guru, zvakasiyana-siyana zvezvigadzirwa, uye rinotora basa guru munzvimbo dzakasiyana-siyana uye nzvimbo dzekukurudzira.PTFE inogona kuonekwa kwese kwese muhupenyu hwedu.
Chechipiri, zvisinei kuti imhando ipi yemakemikari zvinhu, zvisinei kuti iora sei, PTFE inogona kushandiswa.Zvinogona kutaurwa kuti kana pepa rePTFE risingakwanisi kusangana nezvinodiwa zvekudzivisa kuparara, hapana zvimwe zvepurasitiki zvinogona kushandiswa.Kuwedzera kune yakanakisa makemikari kuramba, ayo emagetsi maitiro akanyanya kunaka, izvo zvinoita kuti ive yakakodzera kushandiswa muzviitiko zvine mabhenji makuru uye mabhendi.
Pepa rePTFE rinoshandiswa zvakanyanya muinjiniya mapurasitiki senge tembiricha yakakwira 260 ℃, tembiricha yakaderera -196 ℃, asidhi uye alkali corrosion kuramba, kuramba kwemamiriro ekunze uye kusiri huturu.PTFE inogona kuonekwa mu petroleum, makemikari, mishonga, zvemagetsi uye kunyange maindasitiri ezvekudya.Kunyangwe iyo PTFE ndiro ine chepfu uye ine yakanaka kupfeka kuramba, chinhu chakanaka chekuisa chisimbiso.PTFE (Polytetrafluoroethylene, yakapfupikiswa sePTFE), inowanzonzi "isina-stick coating" kana "nyore-kuchenesa zvinhu".Nyaya iyi ine hunhu hweasidhi uye alkali kuramba uye kuramba kune akasiyana organic zvinonyungudutsa, uye zvinenge zvisinganyunguriki mune zvese zvinonyungudutsa.Panguva imwecheteyo, PTFE ndiro ine hunhu hwekupisa tembiricha kuramba uye yakanyanya kuderera friction coefficient.Pamusoro pekuzora, nzira yekugadzira yePTFE plate coating yavewo yakanakira kuchenesa kwemukati wemukati wepombi dzemvura.
