Iyo yakazara fluorinated polymer iyo iri semi-crystalline, semi-opaque uye chena.Iyo ine yakasarudzika makemikari kuramba isingabatwe neanenge ese makemikari uye zvakare ine yakakwira okisijeni index (kureva kuti isiri-flam).Iine coefficient yakaderera zvikuru ye friction uye yakagadzikana kusvika kune yakakwirira tembiricha.Iyo yakapfava, kuremara zviri nyore, inokurumidza kukambaira uye yakaderera musimba nekushomeka kwemwaranzi.Iyo inodhura uye haigone kunyungudutswa-yakagadziriswa (kunyangwe mufungidziro inonyungudika pa327C, iyo yakanyunguduka viscosity yemagiredhi akajairwa inenge isingaperi) uye saka inoumbwa neupfu sintering nzira.
Zvishandiso zveindasitiri zvinosanganisira mabearings, zvisimbiso, O-mhete, kupisa kwepamusoro kwemagetsi ekudzivirira, mabhanhire asina-stick uye linings yemidziyo nezvimwe, nezvimwewo. Zvinhu zvaro zvisina kujairika zvinoita kuti zvive zvakakosha kune zvakasiyana-siyana zvekushandisa laboratory.
Muchena wakajekaPTFE sphereane pasi kupera uye mwero kushivirira.Polypropylene (PP) ipurasitiki yakasimba, isingaremi, ine nzvimbo yakaoma, yakatsetseka inokodzera kushandiswa uko kuungana kwebhakitiriya kungave chinhu.Kazhinji yakasimba, yakasimba, uye inoshingirira kune tembiricha yakakwira kupfuura polyethylene, polypropylene inewo kumira zvakanaka kumakemikari uye zvinonyungudutsa.
Purasitiki inoreva boka rezvigadzirwa zvekugadzira kana semi-synthetic zvakagadziridzwa kuti zviwane zvivakwa.Hunhu hunonyanya kuzivikanwa hwemapurasitiki huremu hwayo hushoma, machinability, corrosion resistance, uye kazhinji kacho yakanaka yekupisa uye yemagetsi insulating zvivakwa.Mamwe mamakisi epurasitiki anopawo kujeka kwemaziso akafanana negirazi, kudzika-kukweshana kana kuzvigadzika-kuzora nzvimbo, uye yakasarudzika mhedzisiro kuramba.Zvichienderana nemidziyo yavo, mamwe mamakisi epurasitiki anogona kushandiswa seimwe nzira kune simbi, girazi, uye ceramic.Kusiyana nesimbi, mapurasitiki anogona kusangana nezvinokambaira, zvinova deformation inokonzerwa nekuratidzwa kwenguva refu kune inogara ichiremerwa.
Kusimba kwesimba, rinoshandiswa kuratidza kusimba kwechinhu chose, ndiko kushushikana kwepamusoro kwainogona kumira kusati kwapwanyika.Corrosion resistance inotsanangura kugona kwechinhu kudzivirira kuparara kunokonzerwa nemhepo, hunyoro, kana imwe svikiro.Kupfeka kuramba kunoratidza kugona kudzivirira kukuvadzwa kwepasi kunokonzerwa nekusangana nedzimwe nzvimbo.Kuomarara kunotsanangura kugona kwechinhu kutora simba risati ratsemuka, ukuwo kuomarara (kunowanzoyerwa sekuomarara kwemukati) kunotsanangura kuramba kwayo kushanduka kwepasi zvachose.Impact resistance ndiyo chiyero chekugona kwechinhu kutora kuvhunduka kwesimba risati ratsemuka.
- PTFE inopesana nemakemikari mazhinji, kazhinji inomira kutonhora kwakanyanya, uye ine yakaderera-friction, nonstick surface- PTFE kazhinji inomira tembiricha yakakwira kupfuura mamwe mafluoropolymers, akadai seFEP uye ETFE- Ground finish- Rudzi rwakajeka chena- Kushivirira kwakajairwa.
