PTFE: baba vefluoroplastics
Chii chinonzi PTFE?
Sezvo apolymer compound yakagadzirwa ne tetrafluoroethylene ne polymerization, PTFE ine yakanakisa kugadzikana kwemakemikari.uyecorrosion resistance,uye zvavachimwe chezvinhunezvakanakisisaCorrosion resistance.PTFE inogonakurambazvinenge zvesemakemikari,kunzeyakanyungudutswa alkali simbi, chlorine trifluoride, chlorine pentafluoride uye liquid chlorine, zvave zvakadarorinoshandiswa zvakanyanya muzvakasiyana-siyanazviitikoto kuramba asidhi uye organic solvent.PTFE pachayo haina chepfu kuvanhu.
Yakasarudzika zvimiro zvePTFE
PTFE ndiyo yakanyanya kujairika fluoropolymer uye inoratidza kuita kwakanyanya maererano netembiricha, makemikari kuramba uye kwete-tsvimbo.
● Kubhadhara mari;
● Ckuenderera mberi nekushandaat tembiricha ye +260°C;
● Low friction surface;
● Very high magetsi kuramba.

Yakawedzerwa PTFE: iyo microporous fluoropolymer
Chii chakawedzerwa PTFE?
Yakawedzerwa PTFE (ePTFE) imhando nyowani yekurapa polymer zvinhu, iyo yakagadzirwa nepolytetrafluoroethylene resin nekutambanudza uye dzimwe nzira dzakakosha dzekugadzirisa.Iyo chena, elastic uye inochinjika yakawedzera PTFE ine mesh chimiro chakaumbwa kuburikidza ne microfiber kubatana, uye ma microfibers aya anoumba asingaverengeki pores, kuitira kuti yakawedzera PTFE inogona kubhenda zvisina tsarukano.Kuenderana kwayo kwakanaka kweropa uye kuchembera kwebiological kuramba kunobvumira kuti ishandiswe mukugadzira tsinga dzeropa, zvigamba zvemoyo uye zvimwe zvigadzirwa zvekurapa uye inove yakanyanya kunaka inotsiva biological tissue.Iine yakanaka biocompatibility uye yakasarudzika microporous chimiro, ePTFE haina chepfu, haina kenza, uye isiri-allergenic, uye haizobudisi mimwe mhedzisiro.Masero ematishu emunhu uye tsinga dzeropa dzinogona kukura kuita mamicro-pores ayo obva agadzira kubatana kwematishu se autologous tissue.
Yakasarudzika zvivakwa zve PTFE yakawedzera
Yakawedzerwa PTFE inogovera zvivakwa zvakafanana kune PTFE.Nyaya yacho haina chepfu zvachose uye ine hutsanana, uye inopawo tembiricha yekushanda inosvika 260°C.Mukuwedzera, ePTFE inofarira zvinoteveraproperties.
● Kudzivirira kemikari nesimba remutsetse wepamusoro;
● Chemikari inert;
● Kusapinda mvura pamhepo yakaderera;
● Low dielectric constant;
● Yakanakisa radial kuwedzera uye UV kuramba.
Zvikumbiro zve ePTFE
1. Zvigadzirwa zvekurapa
Purely inert ePTFE inogona kushandiswa mumhando dzakasiyana-siyana dzekugadzirisa, kusanganisira mitsipa yeropa uye zvigamba zvekuvandudza zvinyoro zvinyoro uye sutures yekuvhiya yevascular, cardiac, general uye orthopedic kuvhiyiwa, nokudaro vachibatsira vese vanachiremba nevarwere.TheePTFE zvigadzirwa zvekurapa zvinokwanisa kushanda mukuwirirana nematishu emuviri wega uye kudzoreredza basa rawo remazuva ese.
2. Fluorofiber
Eyakawedzera PTFEfibershavesimba rakakwirira, kuderera kwakaderera, abrasion kuramba, uye yakanyanya UV kuramba, saizvozvoensuringkugadzikana kwakanaka uye kutendeseka munzvimbo dzakanyanyisa.Izvikungefaibha inoshanda zvakasiyana-siyana uye inogona kurukwa, kuruka, kurukwa kana kusonerwa mumachira akasiyana siyana, anosanganisira kusungirirwa kurongedza, shinda yekusonesa, machira ekuvaka uye floss yemazino.
3. Gaskets uye sealant
ePTFE ine yakanakisa makemikari uye abrasion kuramba uye kuramba kwakanyanya kune yakakwirira uye yakaderera tembiricha, zvichiita kuti ive yakakodzera kwazvo kutakura uye kuiswa chisimbiso.ofzvinwiwa zvemumaindasitiri.Gaskets uye zvisimbiso zvigadzirwa kubvaSuko, kusanganisira flat, mutete tambo uye munda-akaumbwa sealants, anowanikwa flanges chero saizi kana yakatarwa.
