Magirazi madiki asina chinhu Dzinoshandiswa kakawanda, asi imwe inonyanya kuzivikanwa ndeyekugadzira zvigadzirwa zvakaita se silicone rubber sealants. Chinhu chikuru chinowanikwa ne hollow glass microspheres ndechekuderedza huremu zvinoita kuti zvive nyore kushandisa kuti zvinhu zvifambe zvakanaka. Girazi redu microsphere rinopa insulation yakakwana, kugara kwenguva refu, uye kugadzikana izvo zvinobatsira kwete chete kutakura asiwo mamwe mashandisirwo.
Inoshandiswa sei neRubber?
Panyaya yekutsvagisa, zvinonzwisiswa kuti saizi yechinhu, kugona kwacho kubatana, uye mutoro wainawo pakuona simba, kuramba, uye kuomarara mune zvimwe zvinhu. Ongororo dzinoverengeka dzakasvikawo pakugumisa kuti hunhu hwerabha hwakawedzerwa zvakanyanya apo hollow glass microsphere yakaiswa mazviri. Ongororo dzinoratidzawo kuti kana chimwe chinhu chine viscosity iyo isinganyungudike zvakanyanya, izvozvo zvinogona kugadzirwa nekushandisa hollow glass microspheres mupolyester ne epoxy resins.
Mune imwe ongororo, maitiro e magirazi madiki asina chinhu Yakadzidzwa maererano nekutyoka uye simba kana yakabatanidzwa muzvinhu zvakaita serabha. Magirazi madiki madiki ane simba rakawanda kana tichienzanisa nekugadzirwa kwechinhu chakasanganiswa chakazvimiririra. Uyezve, apo zvinhu zvakasiyana-siyana zvakagadzirwa kubva kumakona madiki egirazi, zvakaonekwa kuti kugara kwenguva refu kwezvinhu zvinova zvakakwirira kana makona madiki egirazi asina chinhu akawandisa muzvinhu panguva yekubatanidzwa. Pamusoro pezvo, kugona kwekutora simba rezvinhu kwakawedzera kusvika pa40% kuburikidza nekushandisa makona madiki egirazi asina chinhu. Chimwe chezvidzidzo zvakakosha chaive maererano nehunhu hwemagirazi madiki egirazi asina chinhu akazadzwa nezvinhu zvinotsiva uye panyaya iyi, zvakaonekwa kuti kuenderana kwakawedzera uye kurasikirwa kwakaderedzwa maererano ne dielectric apo makona madiki egirazi asina chinhu akawedzerwa muhuwandu hwakawanda. Uyezve panyaya yekutyoka maererano nemakona madiki egirazi asina chinhu, zvakaonekwa kuti kuiswa kwemakrospheres kwakasimbisa flexural modulus uye kwakaderedza kuoma nesimba maererano nekutyoka.
Microsphere isina chinhu chinhu chakakosha zvikuru chine zvisikwa zvechisikigo uye ine mashandisirwo akasiyana-siyana. Chinhu chinonyanya kukosha chegomba rayo risina chinhu ndechekuti rinoita kuti pave nekudziya kwakanyanya uye rine mweya wakawanda. Saka, maererano nekushandiswa kwayo muindasitiri yerabha, chinhu chakakosha ndechekuti inoiswa murabha yesilicone iyo inosanganisira kuzadza kwete mabhora asina chinhu chete, asiwo akatyoka muzvikamu zvakasiyana. Kushandiswa muindasitiri yerabha kunoratidzawo kuti kunyangwe magirazi asina chinhu akatyoka, zvinowedzera hunhu uhwu hwataurwa pamusoro apa.
