Chiyambi cha Zinc Borate

Zinc borate ndi chinthu choteteza moto chomwe sichimawononga chilengedwe, chomwe chimagwira ntchito bwino kwambiri, chomwe chimaphatikiza kuletsa moto, kuletsa utsi komanso mphamvu zoletsa kudontha. Chigawo chake chachikulu ndi 2ZnO·3B₂O₃·3.5H₂O, ndipo chimawoneka ngati ufa wosalala kapena wachikasu wofiirira. Ndi kukhazikika kwabwino kwa mankhwala komanso kusinthasintha kwa kapangidwe kake, ndi chinthu chomwe chimakonda kwambiri pakukonzanso zinthu zachitetezo m'mafakitale a rabara ndi pulasitiki, zokutira, waya ndi zingwe.

Chogulitsachi chili ndi kukhazikika kwa kutentha kwakukulu, pang'onopang'ono chimataya madzi a kristalo pamwamba pa 320℃. Sichimawola kapena kusungunuka muukadaulo wokonza kutentha kwambiri monga kutulutsa, kupanga jakisoni ndi kupopera, ndipo chimatha kusunga magwiridwe antchito okhazikika oletsa moto. Sichisungunuka mu zosungunulira zachilengedwe monga madzi, ethanol, benzene ndi acetone, koma chimasungunuka mosavuta mu hydrochloric acid, sulfuric acid ndi dimethyl sulfoxide (DMSO). Ndi kufalikira bwino kwambiri, chimagwirizana bwino ndi zinthu zosiyanasiyana kuphatikizapo PVC, PE, PP, rabara ndi resin, ndipo sichikhudza mawonekedwe, mphamvu yamakina kapena magwiridwe antchito okalamba a zinthu zomalizidwa zitawonjezeredwa.

Ponena za njira yochepetsera moto, zinc borate imachepetsa kutentha kudzera mu kuwonongeka kwa endothermic kutentha kwambiri, imatulutsa madzi a kristalo kuti ichepetse mpweya woyaka, ndikupanga gawo lolimba loteteza ngati galasi kuti lichotse mpweya, motero limapangitsa zotsatira zitatu za kuchedwa kwa moto, kuletsa utsi ndi kuletsa kudontha. Itha kugwiritsidwa ntchito mogwirizana ndi aluminiyamu hydroxide, magnesium hydroxide ndi organophosphorus lawi retardants kuti iwonjezere kwambiri mtundu wa zinthu zochepetsera moto. Ithanso kusintha pang'ono zinthu zochepetsera moto zachikhalidwe monga antimony trioxide, ndikuchepetsa mtengo wa formula.

Chogulitsachi sichili ndi poizoni, sichinunkha fungo komanso sichinaipitse, chikutsatira miyezo yapadziko lonse yoteteza chilengedwe komanso yoletsa moto. Chimagwiritsidwa ntchito kwambiri m'magawo monga mawaya ndi zingwe, zokutira zoteteza moto, mapaipi apulasitiki, zinthu za rabara ndi ma resins a polyester osakhuta. Kaya ndi kusintha kwapamwamba kwa zinthu zopangira mafakitale kapena kutsatira malamulo achitetezo a zinthu zapakhomo, zinc borate imatha kupereka mayankho odalirika oletsa moto, kuthandiza mabizinesi kukwaniritsa kukweza zinthu ndi kupanga zinthu motsatira malamulo.
