Kunzwisisa Kuumbwa uye Zvivakwa zvePTFE Coated Fabrics
Iyo Mamiriro ePTFE Coated Fabrics
PTFE machira akavharidzirwa ane base zvinhu, kazhinji fiberglass, yakavharwa ne polytetrafluoroethylene (PTFE). Uku kusanganiswa kwakasiyana kunoguma mune chinhu chinotora simba refiberglass uye kemikari inertness yePTFE. Iyo fiberglass substrate inopa yakanakisa tensile simba uye dimensional kugadzikana, nepo PTFE coating ichipa isiri-tsvimbo zvivakwa, makemikari kuramba, uye inosimudzira kupisa kuramba.
Maitiro ekuputira anosanganisira kushandisa akawanda akaturikidzana ePTFE kune iyo fiberglass substrate. The ukobvu uye nhamba akaturikidzana anogona customized kusangana chaiwo zvinodiwa. Mamwe machira anogona kunge aine PTFE yemukati kubva pa15% kune porous application kusvika 85% yezvigadzirwa zvakavharwa zvakanyanya. Izvi zvakasiyana-siyana zvinobvumira vagadziri kuti vagadzirise zvivakwa zvejira kune akasiyana maindasitiri nekutengesa kushandiswa.
Thermal Properties yePTFE
PTFE, chikamu chakakosha mune aya Teflon akajaidzwa machira , anozvikudza zvinoshamisa ekupisa. Iine nzvimbo yekunyungudika inosvika 327°C (620°F) uye inogona kuchengetedza zvinhu zvayo patembiricha inosvika 260°C (500°F). Uku kupikisa kwepamusoro-soro kwakakosha mumashandisirwo asingadziviriri moto, sezvo achibvumira jira kuti richengetedze kuvimbika kwayo uye hunhu hwekudzivirira kunyangwe painenge ichipisa zvakanyanya.
Uyezve, PTFE ine yakaderera yekupisa conductivity, zvinoreva kuti haina kukurumidza kutamisa kupisa. Iyi pfuma inobatsira pakubudirira kwayo sechivharo chekupisa, ichibatsira kuderedza kupisa kwekushisa mumamiriro emoto. Iyo midziyo inewo yakakwira chaiyo yekupisa simba, ichibvumira kuti itore yakakura yakawanda yesimba rekupisa isati yasvika tembiricha yakakwira zvakanyanya.
Kemikari Kugadzikana uye Kuderera Kupisa
Chimwe chezvikonzero zvakakosha zvinoita kuti moto udzivirirwe kwePTFE machira akafukidzwa ndiko kugadzikana kwemakemikari ePTFE. Iyo yakasimba kabhoni-fluorine zvisungo muPTFE inoita kuti ive yakanyanya kupikisa kuita kwemakemikari, kusanganisira oxidation. Kugadzikana uku kunoreva kuti PTFE haitsigire kupisa, zvichiita kuti ive isingadziviriri moto.
Kana yaiswa pamoto, PTFE inoita kutsva pane kupisa. Iyi nzira yekuchaya inogadzira chidziviriro chinodzivirira kupararira kwemoto uye inobatsira kuchengetedza chimiro chejira. Iyo yakaderera kupisa kwePTFE, yakasanganiswa nekugona kwayo kuzvidzima, inoita kuti ive sarudzo yakanakisa yezvikumbiro uko kuchengetedzwa kwemoto kunonyanya kukosha.
Moto Resistance Standards uye Kuedzwa kwePTFE Coated Fabrics
International Fire Resistance Standards
PTFE machira akavharwa ari pasi pekuyedzwa kwakasimba kuti ave nechokwadi chekuti anosangana neyakaomesesa yekudzivirira moto mwero. Aya mazinga anosiyana zvichienderana nekwakatarisirwa kushandiswa uye nenzvimbo. Zvimwe zvezviyero zvinozivikanwa pasi rose zvinosanganisira:
