Aluminiyamu yosinthidwa ya hydroxide - zinthu zoletsa moto

Aluminium hydroxide ufa wokhala ndi retardant lawi, Kuchotsa utsi, kudzaza ndi ntchito zina zingapo, kumatha kupanga synergistic flame retardant effect ndi phosphorous ndi zinthu zina, ndi mitundu yambiri ya mankhwala, yakhala magetsi, mankhwala, chingwe, mapulasitiki, mphira ndi mafakitale ena ofunika kwambiri oteteza chilengedwe. wochedwa.Aluminiyamu hydroxide ngati filler inorganic flame retardant, kuti akwaniritse bwino lawi retardant zotsatira, kudzaza kuchuluka kumafunika 40%, ngakhale mpaka 60%, koma kuchuluka kudzazidwa osati kwambiri zimakhudza kwambiri makina katundu, ndi extrusion. ndi katundu processing kukhala woipitsitsa.Choncho, kusinthidwa pamwamba ndikofunikira.

Sankhani zosintha zosiyanasiyana zapamtunda ndi kuchuluka kosiyanasiyana kwa zosintha zonyowa zosinthaaluminium hydroxide.Kupyolera mu mafuta a mayamwidwe a aluminiyamu hydroxide ufa isanayambe komanso itatha kusinthidwa, mawonekedwe a pamwamba a aluminium hydroxide powder asintha mwachiwonekere, hydrophilicity ndi mafuta mayamwidwe mtengo unachepa kwambiri, ndipo kubalalitsidwa mu gawo organic kuwonjezeka mwachionekere.Kusinthidwa kwapamwamba kumakhalanso ndi zotsatira pa katundu wa aluminium hydroxide composite system.Njira yochepetsera lawi ndi njira yolimbikitsira ya superfine activated aluminium hydroxide idawunikidwa ndi kusanthula kwa thermogravimetric ndi scanning electron microscopy.Kusinthidwa pamwamba kumatha kusintha kwambiri zida zonse za aluminium hydroxide yodzaza PVC system.Ma organic compounds angapo adasankhidwa kuti asinthe pamwamba pa alumina hydroxide powder.Kupyolera mu kusanthula mafuta mayamwidwe mtengo, digiri kutsegula ndi tinthu kukula kwa ufa kusinthidwa, ndi organic kusinthidwa anapanga tinthu kukula kwa aluminiyamu hydroxide ufa ang'onoang'ono.Njira yolumikizira mankhwala m'malo mwa njira yachikhalidwe yopaka thupi imatha kupititsa patsogolo kukhazikika kwa kubalalitsidwa komanso kuyanjana kwa nano-hydroxide flame retardant mu ma polima achilengedwe.

Kaya njira ya zotayidwa hydroxide kusinthidwa, mungagwiritse ntchito ufa pamwamba kusinthidwa makina zisa akupera, zisa akupera kusinthidwa ndondomeko ndi mtundu wa imayenera mphepo kusesa dongosolo, zinthu kudzera mpweya otaya dongosolo kusintha makhalidwe, osachepera akuchitira mphamvu. matani 0.05 pa ola, kuchuluka kwa matani 15 pa ola.
