Polytetrafluoroethylene (PTFE) parizvino ndiyo inonyanya kushandiswa fluoropolymer, ndiyo inonyanya kurwisa kemikari corrosion, ine yakanakisa dielectric zvivakwa uye yakawanda yekushanda tembiricha mhando, inozivikanwa se "mambo wepurasitiki".
PTFE ine tembiricha yekudzivirira (inogona kushandiswa kwenguva yakareba mukupisa kwe200 ~ 260 ℃), kushomeka kwekushisa kwepasi (kunogona kushandiswa kwenguva yakareba pazasi -100 ℃), kushomeka kwemarara (ine yakakwira makemikari inertness), kupikisa mamiriro ekunze (yakakwirira mumhepo kuchembera kuramba), mafuta ekuzora (aine diki diki coefficient of friction), isinganamire (kushushikana kwepamusoro kwakadzikira kwazvo, hakusi nyore kuomerera), kugarisana kwakanaka kwevanhu (ine yakanaka physiological inertness, isina chepfu) , yakanaka magetsi ekudzivirira (yakakwirira insulation, uye isina kukanganiswa nekushisa, humidity) uye nhevedzano yezvakanakira,PTFE, maitiro aya anonyatsoenderana nekugadzirisa kwayo molecular.
Munda wemakemikari
PTFE haina kunyungudika kana kuzvimba mune chero zvinwiwa zvinozivikanwa, sakaPTFEzvikamu hazvichinje saizi mune chero svikiro, zvisinei kuti zvakashandiswa kwenguva yakareba sei.PTFE inogadzira midziyo mihombe ine madziro yakatetepa iyo inoshandiswa zvakanyanya mumarabhoritari nemafekitari anoshandisa zvinwiwa zvinoparadza, uye inoshandiswa zvakanyanya muzvisimbiso, pombi, pombi, mavharuvhu, nezvimwe.
Mechanical field
Hazvina mhosva kuti rudzii rwemuchina nemidziyo, nzvimbo dzinotsvedza dzinoda kuzorwa kuti dzideredze friction factor, kupfeka uye kupisa kuti ive nechokwadi chekushanda kwemuchina nemidziyo yemagetsi, iko kurongeka uye mashandisiro emagetsi.PTFE's low coefficient of friction and self-lubricating properties inoita kuti ishandiswe zvakanyanya mukugadzira mabearings, piston rings, machine tool guides and sealing materials, asi nekuti inodhura, inowanzo shandiswa mumidziyo chaiyo kana inoda asidhi uye alkali inodzivirira. nharaunda.
Nzvimbo yemagetsi
PTFE's yakanakisa dielectric properties, iyo inenge yakazvimirira patembiricha uye frequency, pamwe nekudzika kwayo kwepamusoro kupisa, inoita kuti ive insulator yemagetsi isingadzokeki, kunyanya pamhepo uye tembiricha uye munzvimbo dzine mwando.
Nhasi mafomu akawanda ePTFE zvinhu anoita basa rakakosha mumunda wemagetsi nemagetsi ekudzivirira.PTFE girazi lacquer jira uye girazi jira rinoshandiswa kugadzira yakakwirira-tembiricha uye yakakwirira-frequency insulation zvinhu, izvo zvinogona kushandiswa setiraiti kutaurirana uye makomputa.Firimu rePTFE rinoshandiswa kugadzira ma capacitor, senge insulation layer pakati pezviridzwa, gaskets, tambo, nezvimwe.PTFEmachubhu akatetepa-ane madziro emadhayamita akasiyana anoshandiswa kune lead-muwaya maoko, kupisa-kupwanyika chubhu uye spiral chubhu, insulated pilot chubhu yemajenareta, nezvimwe.
PTFE chinhu chinoshamisa, chine mukana wakawanda wakamirira kuti vanhu vaongorore.Vashandi vezvishandiso zvitsva havafanire kungoziva chete zvimiro zvemidziyo, asi zvakare kuwedzera maitiro avo kuti atipe akasiyana mikana yehupenyu huri nani.
