Fiberglass uye jira rayo pamusoro nekuputira PTFE, silicone rabha, vermiculite uye kumwe kugadzirisa kurapwa kunogona kuvandudza nekusimudzira kushanda kwefiberglass nejira rayo.

1. PTFE yakanamirwa pamusoro pefiberglassnemicheka yayo

PTFE ine yakakwira makemikari kugadzikana, yakasarudzika isina-kunamatira, yakanakisa kuchembera kuramba, corrosion resistance, self-kuchenesa uye humwe hunhu hwakanaka, asi kune hurombo hwemagetsi emagetsi, kushomeka kwekusapfeka, kushomeka kwemafuta uye humwe hurema. zvemuviri uye zvemakemikari zvimiro, fiberglass uye jira rayo pamusoro rakaputirwaPTFE, kwete chete kugadzirisa kukanganisa kwePTFE uye kuvandudza, uye kutambawo zvakanakira fiberglass kushanda, uye panguva imwechete kuderedza fiberglass nemicheka yayo. Kuita, uku ichideredza brittleness yefiberglass, kuumbwa kwesimba rakakwirira, yakanaka abrasion resistance, kuchembera-resistant fiberglass / PTFE zvinhu. Fiberglass yakavharwa PTFE inowanzo shandisa maitiro akawanda ekuisa mukati, mushure mekupisa kurapwa kwefiberglass jira kuburikidza neiyo impregnation tank yakavharwa nePTFE dispersion, uyezve kuomesa, kubika, sintering uye mamwe marapiro, iyo yakawandisa mvura uye solvent evaporation ye emulsion, ichisiya PTFE resin zvidimbu zvakanamatira. kune jira refiberglass, zvinyorwa zvine zvese PTFE maitiro, asiwo kuita kwakanakisa kwefiberglass, inowanzoshandiswa se kuvaka Nyaya yacho ine zvose PTFE maitiro uye kushanda kwakanakisisa kwefiberglass, uye inowanzoshandiswa sezvivakwa zvekuvaka, zvigadzirwa zvekudzivirira, friction materials, etc. Inoshandiswa zvakanyanya mukuvaka, magetsi uye mamwe minda.

2. Fiberglass uye jira rayo pamusoro rakaputirwa nesilicone rubber

Silicone rabha ine yakanaka magetsi ekudzivirira, yakakwira uye yakaderera tembiricha kuramba, oksijeni kuchembera kuramba, nezvimwewo, mufiberglass uye jira rayo rakaputirwa nesilicone rabha, rinogona kuvandudza kuita kwekupeta kwefiberglassuye kupfeka kuramba. Fiberglass nemachira ayo senge substrate, yakaputirwa nesilicone rabha kuti igadzire machira akavharidzirwa efiberglass, ane simba rakanyanya kusimba, kugadzikana kwedimensional, kunaka kwemagetsi ekudzivirira uye kudzivirira kwemakemikari ekuora uye humwe hunhu hwakanaka, kazhinji sechinhu chinodzivirira magetsi, chinogona kugadzirwa. insulating jira, casing, nezvimwewo; sechinhu chinopisa chinogona kushandiswa sepombi, matangi mukati nekunze kweiyo anticorrosive layer; asiwo sefirimu rekuvaka, kurongedza zvinhu, senge mukuvaka, simba uye mamwe maindasitiri. Inogonawo kushandiswa sefirimu rekuvakauye kurongedza zvinhu mukuvaka, simba uye mamwe maindasitiri.

3. Kupfekedza vermiculite pamusoro pe fiberglass uye machira ayo

Vermiculite iminerari ine magnesium-ine hydroaluminosilicate inokwanisa kumira kutonhora kwakanyanya kusvika 1250°C. Mushure mekupisa nekuwedzerwa, huwandu hwayo hunowedzera uye kupisa kwayo kwakadzikira, uye yakawedzera vermiculite ine yakaderera density, yakanaka makemikari insulating zvivakwa, kupisa uye kuvharisa inzwi, uye moto uye chando kuramba. Kunyange zvazvo fiberglass ine yakanaka kupisa kupisa, asi kushandiswa kwenguva refu kwekushisa hakufaniri kunge kwakanyanyisa, apo murazvo wakazaruka unogona kunyange kupinda mukati mezvigadzirwa zvayo, vermiculite yakaputirwa mu fiberglass uye jira ravo pamusoro, vermiculite inogona kuvandudza moto wekudzivirira. fiberglass, asi zvakare inotora chikamu mumhedzisiro yemoto inodzoreredza kupisa kupisa. Vermiculite-yakavharwa nefiberglass zvigadzirwa zvine yakakwirira kupisa kupisa uye yakanaka kupisa kupisa uye murazvo unodzoreredza zvivakwa, uye inoshandiswa mukudzivirira welding, kudzivirira moto,kuputira pombizvichingoenda zvakadaro.
