Iko kuenderera mberi kushandisa tembiricha yepeek (positeethethertherone) zvinhu zvakakwirira zvakanyanya (inenge yakaomesesa zvakanyanya uye yakaomesesa zvakanyanya, uye yakasarudzika yakasarudzika simba uye yakasarudzika simba rekuneta. Uye zvakare, kupokana kwayo kupisa uye kusiri-deformation performance uye makemikari kugadzikana kwakanaka. Zvinyorwa zvine zvazvinoita zvakanakisa dielectric nzvimbo kusvikira tembiricha inosvika madhigirii mazana maviri nemakumi maviri, uye inogona kuramba simba ray kurira. Peek ine zvinhu zvakanakisa zvakaringana, zvinhu zvakanaka zvekushambadzira, kupisa kwakanyanya, uye kupokana kwepamusoro kwemakemikari, kuchiita kuti ive yakawanda yepurasitiki yepurasitiki.

Zvimiro: Simba remagetsi, kuomarara, kuramba kwakasimba, kupokana kwemakemikari uye kupokana nekupokana, nezvimwe zvekurapa.

PVDF (PolyVinylidene Fluoride) ine yakakwira kuomarara uye nekumanikidza-kutakura kugona kupfuura kwayo kwe ptfecart yePTFE, asi haina kunyatsoita uye yakawandisa. Iyo ine simba rakanyanya uye rakaomesesa pasi pemamiriro ezvinhu epasi ekushisa, uye anogona kudzimwa ari oga. Tembiricha yayo yekushanda iri pakati -30 madhigirii uye zana nemakumi mashanu. PVDF yakagadzikana kune chlorides, bantides uye magetsi majasi.

Zvimiro: Yakakura mumhepo, yakakwira inobvumidzwa tembiricha (inogona kushanda ichiramba ichingopera madhigirii), yakanakisa kemikari kupesana uye hydrolysis kuramba, yakasarudzika UV kuramba uye kupokana kwemamiriro ekunze. Simba rakasimba rekusimba, kuomarara kwakanaka, kwakanaka kupokana. Kutsvedza kwakanaka uye kupfeka kurwisa. Zvakanyanyisa kupenya kwekupenya, yakanaka yemagetsi yekunzwa zvinhu.

Asi maererano ne tembiricha uye michina yezvimiro, peek iri nani kupfuura PVDF. Hony mapurasitiki akaiswa kumunda wevapurasitiki akakosha kwemakore akawanda, uye anogona kuita maitiro akasiyana siyana akaumbwa senge kuumbwa, jekiseni kuumba, kumanikidza kuumba, uye kuumbwa kwemuchina. Maererano nemadhirowa evatengi uye kana semuenzaniso zvinodiwa, kukura uye kugadzira jekiseni kuumba kuumbwa, uye kugadzirisa zvinhu zvehuwandu uye zvakapedza zvigadzirwa zvakasiyana uye zvinoshandiswa.
