1. Chii chinonzi fiberglass powder
Upfu hwefiberglass, hunozivikanwawo seupfu hwefiberglass, upfu hunowanikwa nekucheka, kukuya uye kuvharira tambo dzefiberglass dzakagadzirwa zvakananga. Chena kana kuti isina kuchena.

2. Ndezvipi zvinoshandiswa neupfu hwefiberglass
Mashandisirwo makuru eupfu hwefiberglass ndeaya:

• Sechinozadza chigadzirwa kuti chiwedzere kuomarara, simba rekudzvanya, kuderedza kudzikira kwechigadzirwa, upamhi hwevanga rekupfeka, kupera, uye mutengo wekugadzira, chinoshandiswa zvakanyanya mumaresini akasiyana-siyana ethermosetting nemaresini ethermoplastic, akadai sePTFE yakazadzwa, nylon yakawedzerwa, PP yakasimbiswa, PE, PBT, ABS, epoxy yakasimbiswa, rabha yakasimbiswa, epoxy pasi, thermal insulation coating, nezvimwewo. Kuwedzera huwandu hwakati hwefiberglass powder kune resin kunogona kuwedzera zvakanyanya hunhu hwakasiyana hwechigadzirwa, kusanganisira kuomarara, kuramba kutsemuka, Zvinokwanisikawo kuvandudza kugadzikana kwe resin binder uye kuderedza mutengo wekugadzira wechinhu chacho.
• Upfu hwefiberglass hunodzivirira kupfekwa zvakanaka uye hunoshandiswawo zvakanyanya muzvinhu zvekukweshana, zvakaita semabrake pads, mavhiri ekupolisha, magrinding wheel pads, mafriction pads, mapaipi anodzivirira kupfekwa, mabearings anodzivirira kupfekwa, nezvimwewo.
• Upfu hwefiberglass hunoshandiswawo muindasitiri yekuvaka. Basa guru nderekuwedzera simba. Hunogona kushandiswa sechikamu chekudzivirira kupisa kwemadziro ekunze echivako, kushongedza madziro emukati, kudzivirira hunyoro uye kupisa kwemadziro emukati, nezvimwewo. Hunogona zvakare kushandiswa kusimbisa fiber isina organic nekudzivirira kwakanaka kwekongiri yemortar inodzivirira kunyura uye kupwanyika. Shandisa polyester fiber, lignin fiber nezvimwe zvigadzirwa zvekusimbisa kongiri yemortar.

3. Zvinodiwa zvehunyanzvi zveupfu hwefiberglass
Upfu hwefiberglass chigadzirwa chinogadzirwa nefiberglass yekukuya, uye zvinodiwa pahunyanzvi zvinosanganisira:

• Hunhu hweAlkali metal oxide

Huremu hwealkali metal oxide muupfu hwefiberglass husina alkali hahufanirwe kudarika 0.8%, uye huwandu hwealkali metal oxide muupfu hwefiberglass hwepakati pealkali metal hunofanirwa kunge huri 11.6% ~ 12.4%.

•  Avhareji yedhayamita yefaibha

Avhareji yedhayamita yeupfu hwefiberglass haifanirwe kudarika dhayamita yepamusoro pamwe chete kana kubvisa 15%.

•  Avhareji yehurefu hwefaibha

Avhareji yehurefu hwefiber ye fiberglass powder inosiyana zvichienderana nezvinodiwa zvakasiyana uye mamodheru.

•  Hunyoro

Hunyoro hwehupfu hwefiberglass hunofanirwa kunge husingapfuure 0.1%, uye hunyoro hwehupfu hwefiberglass hunofanirwa kunge husingapfuure 0.5%.

•  Zviri mukati zvinobvira

Hupfu hwefiberglass hunobvira hahufanirwe kudarika kukosha kwe "plus" kana "minus"

•  Hunhu hwekutaridzika

Upfu hwegirazi refiberglass huchena kana kuti hwakachena, uye hunofanira kunge husina mavara kana tsvina.
