Kubva paDombo Rakaoma kuenda kuChishamiso cheTekinoroji: Kuchinja kweQuartz Glass Fiber

Chii chinonzi quartz glass fiber?

Faibha yegirazi yeQuartzifayibha isina kugadzirwa ine silicon dioxide (SiO₂) ine kuchena kwe ≥99.9% sechinhu chikuru chayo. Inogadzirwa kuburikidza nekushandiswa kwetsvimbo ye silica yakasanganiswa. Fayibha iyi inobatanidza hunhu hwakanaka uye hunhu hwe quartz yakasimba, zvichiita kuti ive chinhu chakanaka chinodzivirira kupisa kwakanyanya. Inogona zvakare kusanganiswa ne ceramics, alumina, nitrides, nezvimwe zvinhu mumhando dzakasiyana-siyana kugadzira zvinhu zvine hunhu hwakakosha. Yarn ye fayibha ye quartz inogadzirwa nekumonera uye kutenderedza filaments dzisina kucheneswa.

Sei fiber ye quartz yakasimba kudaro, uye ndeapi maitiro ayo akanaka?

1. Fiber yegirazi re quartz ine simba rakanaka kwazvo rekudzivirira kupisa kwakanyanya. Tembiricha yayo inoshanda kwenguva refu ndeye 1050-1200℃, uye simba rayo rekudzivirira kupisa nekukurumidza rinosvika 1700℃. Inoramba yakasimba mumamiriro ekunze ekunze, haipindi kupisa kwakanyanya uye kupiswa kwemhepo, uye inogona kushandiswa mukudzivirira kupisa kwemhepo, ma nozzles einjini dzeroketi, uye zvinhu zvinodzivirira kupisa zvakanyanya.

2. Ine hunhu hwakanaka hwe dielectric uye kutumirwa kwemafungu kwakanaka. Kugara kwayo kwe dielectric kwakaderera kusvika pa3.7, uye kuderedzwa kwayo kwe dielectric kuri <0.001>. Ine kuderedzwa kwechiratidzo che high-frequency uye kutumirwa kwemafungu makuru (kusvika pa99.3%), inova imwe yehunhu hukuru hwekushanda kwayo inoita kuti ikodzere ma radar domes, antenna radomes, 5G communication substrates, uye zvishandiso zvekudzivirira zvombo.

3. Fiber ye quartz ine simba guru remakanika. Simba rayo rekudhonza rinogona kusvika >1500MPa, density 2.29g/cm³, chimiro chayo chakareruka asi chakasimba, zvichideredza huremu hwemidziyo uku ichiramba yakasimba. Uyezve, inogona kusanganiswa nezvimwe zvinhu kugadzira zvinosimbisa zvine simba repamusoro, zvichiita kuti ive chinhu chakakosha chezvikamu zve satellite.

4. Kugadzikana kwayo kwakanyanya kwemakemikari kunoshamisa. Nehuwandu hweSiO₂ ≥99.9%, inoratidza kusagadzikana kwakasimba kwemakemikari uye kuramba ngura, ichichinjika kunzvimbo dzakaoma dzemakemikari. Izvi zvinoita kuti ive sarudzo yakakodzera yemidziyo yekugadzira semiconductor, zvinhu zvekusefa zvinopisa zvakanyanya, uye zvinhu zvinotakura makemikari.

Zvigadzirwa zvakagadzirwa negirazi re quartz fiber zvinoshandiswa muminda yakawanda.

1. Makushe eQuartz neQuartz anoshandiswa nevanhu vanoita bvunzo dzekupisa kwakanyanya. Aya makushe mapfupi anopfava akagadzirwa nemakushe eQuartz anoputika kana kudhonzwa, anogona kushandiswa zvakananga kana kugadzirwa kuti ave felt. 1. Makushe eQuartz anozivikanwa nekureruka kwawo, ane maburi uye kupisa kwakaderera, zvichiita kuti ive chinhu chakanaka chekudzivirira kupisa kwakanyanya. Inowanzoshandiswa muzvikamu zvekudzivirira zvemuchadenga kana mumidziyo yeindasitiri inodziya zvakanyanya. Zvikamu zvekudzivirira zvichena, zvinopfava, zvakaita sedonje uye zvikamu zvekudzivirira zvakaita sequilt pamapuratifomu muzvitofu zverabhoritari uye zvitofu zvinonamira i quartz wool nequartz wool felt.

2. Kucheka kunoramba kuripofiber dze quartzKusvika pakureba kwakafanotaurwa kunoburitsa mafiber equartz akachekwa. Izvi zvinogona kusanganiswa mumaresini anodzivirira kupisa zvakanyanya sezvinhu zvinosimbisa uye zvinhu zvinotumira mafungu, uye zvoumbwa pamwe chete kugadzira zvinhu zvinodzivirira kupisa kana zvinodzivirira kupisa zvekugadzira zvinhu zvakaita semarobhoti emisipiresi.

3. Yarn yeQuartz fiber ishinda inoenderera mberi uye inoshanda sehwaro hwekurukwa kunotevera. Seimwe yeshinda dzisina kusimba dzinochinjika uye dzinoshanda zvakanaka mu dielectrical inorganic, inowanzoshandiswa sechikamu chekusimbisa kuruka machira akasiyana-siyana kana zvakananga pakumonera nekuumba zvinhu zvakasanganiswa. Uyezve, tekinoroji yepamusoro yekuruka ine mativi matatu inobvumira kuti shinda dzibatanidzwe muchadenga. Chivako ichi chine hunhu hwakasimba, zvichiita kuti chive chisina chinhu chakakodzera kugadzira zvinhu zvine chimiro chakaomarara, zvinotakura mutoro wakawanda senge rocket engine nozzles.

4. Jira refaibha reQuartzInorukwa kubva mushinda uchishandisa weave isina kusimba, twill weave, satin weave, nedzimwe nzira. Sechinhu chinosimbisa, inosanganiswa nematrices akadai sepolyimide ne epoxy resin kugadzira zvikamu zvechimiro zvinopisa zvakanyanya zvendege, maroketi, uye zvombo zvinokandwa, pamwe nezvinhu zvinodzivirira kupisa kana zvinodzivirira ablation zve satellite antennas uye high-frequency printed circuit boards.
