Nheyo uye zvakanakira magnesium hydroxide flame retardant
Magnesium hydroxide is inorganic flame retardant filler, ine tarisiro yakafara yekushandisa mune polymer-based composite zvinhu.Magnesium hydroxide flame retardant inoora uye inoburitsa mvura kana yapiswa, inobata kupisa, inoderedza tembiricha yemurazvo pamusoro pechinhu chepolymer, uye inonoke maitiro ekuderera kwepolymer kuita yakaderera mamorekuru.Panguva imwecheteyo, iyo yakasunungurwa mhute yemvura inogona kuderedza okisijeni pamusoro pechinhu chacho, ichidzivisa kupisa kwezvinhu.Naizvozvo, magnesium hydroxide flame retardant ine zvakanakira kwete-chepfu, yakaderera utsi, uye hapana chechipiri kusvibiswa.Iyo inoshamwaridzana nemamiriro ekunze murazvo retardant.
Iko kudikanwa kwekugadzirisa magnesium hydroxide
Nekudaro, zvichienzaniswa nehalogen-based flame retardants, magnesium hydroxide flame retardants inoda yakakwira yekuzadza mari kuti iwane yakafanana murazvo retardant mhedzisiro, kazhinji pamusoro pe50%.Nekuti magnesium hydroxide iri inorganic substance, haina kuenderana nepolymer-based materials.Huwandu hwekuzadza hwakakura huchakanganisa ma mechanic zvivakwa zve composite zvinhu.Kuti ugadzirise dambudziko iri, zvinodikanwa kugadzirisa pamusoro pe magnesium hydroxide kuti ivandudze kuenderana kwayo ne polymer-based materials, kuvandudza dispersibility yayo muzvinhu zvinoumbwa, kuwedzera basa rayo repamusoro, nekudaro kuderedza dosi, kuvandudza kushanda kwayo kwemurazvo, uye kuchengetedza. kana kuvandudza ma mechanical properties ye composite zvinhu.
Nzira dzekugadzirisa magnesium hydroxide
Parizvino, kune nzira mbiri dzakajairika dzekugadzirisa magnesium hydroxide: yakaoma nzira uye nzira yekunyorova.Iyo yakaoma nzira yekushandura ndeyekusanganisa yakaoma magnesium hydroxide nehuwandu hwakakodzera hweinert solvent, kuipfapfaidza necoupling agent kana imwe nzvimbo yekurapa mushonga, uye kuisanganisa mumuchina wekukanyira wakaderera wekugadzirisa kurapwa.Iyo yekunyorova nzira yekugadziridza ndeyekumisa magnesium hydroxide mumvura kana zvimwe zvinonyungudutsa, zvakananga kuwedzera pamusoro pekurapa mumiriri kana dispersant, uye kuigadzirisa pasi pekukurudzira.Nzira mbiri idzi dzine zvadzo zvakanakira nekuipira uye dzinoda kusarudzwa zvichienderana nemamiriro ezvinhu.Pamusoro peiyo nzira yekushandura yepamusoro, nzira yekunatsiridza inogona zvakare kushandiswa kupwanya magnesium hydroxide poda kusvika padanho re nanometer, kuwedzera nzvimbo yayo yekubatana nepolymer matrix, kusimudzira hukama hwayo nepolymer, uye nekudaro kuvandudza mhedzisiro yayo yemurazvo.
