Mumunda wezvinhu zvepurasitiki,PTFE(polytetrafluoroethylene) inoonekwa semhinduro yakanaka uye inoshanda zvakasiyana-siyana pakushandisa kwakasiyana-siyana. Nehunhu hwayo hwakanaka uye hwakasiyana-siyana hwekushandisa, yave chinhu chakakosha mumaindasitiri akasiyana-siyana. Muchinyorwa chino cheblog, tichaongorora hunhu uye mabhenefiti ePTFE rods, dziripo mumhando dzakaburitswa uye dzakaumbwa.
Kutanga nemhando dzakaburitswa, tsvimbo idzi dzinogadzirwa muhukuru hwakajairwa, kubva pa 1/8" mudhayamita kusvika pa 8". Hurefu hwese hwe PTFE yakaburitswa hunosvika 1000mm, izvo zvinoita kuti ishandiswe zvakanyanya. Kune rumwe rutivi, yakaburitswaPTFE tsvimbos inowanikwa mudhayamita inosvika 16 inches uye kureba kwakanyanya kwe300 mm. Sarudzo dzakasiyana-siyana dzehukuru dzinoita kuti vatengi vawane chigadzirwa chinonyatsokodzera zvavanoda.
Chimwe chezvakanakira zvakakosha zvePTFE tsvimbos isimba rinowedzerwa kuburikidza nekushandisa zvinhu zvekuzadza (kusimbisa). Matavi aya anogona kugadzirwa nezvinhu zvakasiyana-siyana zvekusimbisa zvakaita sefiberglass, graphite nebronze. Izvi zvinosimbisa zvinovandudza zvakanyanya hunhu hwePTFE, zvichiita kuti ive sarudzo yakakodzera yekushandiswa kwakaoma.
Kusashanda zvakanaka kwetsvimbo dzePTFE ndiko kumwe kwehunhu hukuru hwetsvimbo dzePTFE, chinhu ichi chine hupenyu hwakanaka hwekukwegura pakati pemapurasitiki. Izvi zvinoreva kuti tsvimbo dzePTFE dzinogona kutsungirira mamiriro ekunze akaoma pasina kurasikirwa nehunhu hwadzo kana kuora nekufamba kwenguva. Pamusoro pezvo,PTFE tsvimboDzinodzivirira ngura zvakanyanya, zvichiita kuti dzive dzakakodzera kushandiswa neacid yakasimba, mabhesi, mvura, uye zvakasiyana-siyana zvinonyungudutsa organic.
Chimwe chinhu chinoonekwa pamatanda ePTFE ndechekuti ane mafuta akawanda, ayo anowanzoonekwa seane mafuta mashoma ekukweshana pakati pemapurasitiki. Nemafuta ekukweshana akaderera se0.04, matanda ePTFE anopa mafuta akanaka kwazvo, anoderedza kupera uye anoona kuti anoshanda zvakanaka mumhando dzakasiyana-siyana dzemashandisirwo.
Chimwe chezvinhu zvinonyanya kufadza PTFE kugona kwayo kutsungirira tembiricha yakakwira.PTFE tsvimbos dzinogona kutsungirira tembiricha dzenguva refu dze200 kusvika 260 degrees Celsius, zvichiita kuti dzikwanise kushandiswa munzvimbo dzinopisa zvakanyanya. Kusapisa kwakanyanya uku kunowedzera kuvimbika uye kugara kwenguva refu kwePTFE rods.
Kusiyana neizvi, tsvimbo dzePTFE dzinoratidzawo kushanda zvakanaka patembiricha yakaderera. Kunyangwe tembiricha ikadonha kusvika -196 degrees Celsius, tsvimbo yePTFE inogona kuramba yakarebesa ne5%, ichiratidza kuchinjika kwayo kwakanaka uye kusimba mumamiriro ekunze anotonhora zvikuru.
Pamusoro pezvo, tsvimbo dzePTFE dzinogona kuchekwa kuti dzibatanidzwe, zvichibvumira kubatana kwakachengeteka uye kushandiswa kwakawanda. Izvi zvinoita kuti tsvimbo dzePTFE dzive dzakanakira mapurojekiti akasiyana-siyana ekuvaka uye einjiniya.
Mukupedzisa, tsvimbo dzePTFE mhinduro inoshanda zvakasiyana-siyana uye yakavimbika ine hunhu hunoshamisa. Dzinowanikwa mumhando dzakaburitswa uye dzakaumbwa, pamwe nesarudzo dzakasiyana dzehukuru, zvichibvumira kushanduka-shanduka kusangana nezvinodiwa zvakasiyana zvekushandisa. Kushanda kwakawedzerwa kunowanikwa nezvinhu zvinosimbisa kunowedzera huwandu hwekushandisaPTFE tsvimboKubva pakuramba mamiriro ekunze uye ngura kusvika pakunyorova kwakanyanya, kuramba kupisa uye kunyange kushanda zvakanaka, PTFE rods dzinopa musanganiswa wehunhu husina muganho. Saka kunyangwe uchida chinhu chakavimbika chekushandisa muchimiro, indasitiri yemakemikari, kana chimwewo chinhu, funga nezvePTFE rods nekuda kwekushanda kwayo kwakanaka uye kugara kwenguva refu.
