Iingenelo zeMagnesium Hydroxide Flame Retardant

I-Magnesium hydroxide luhlobo lwesiqhelo lwe-filler-based flame retardant. Xa ibekwe kubushushu, iyabola kwaye ikhuphe amanzi abotshelelweyo, ifunxe ubushushu obufihlakeleyo. Oku kunciphisa ubushushu bomphezulu wezinto ezidityanisiweyo elangatyeni, kuthintele ukubola kwe-polymer kwaye kupholise iigesi ezivuthayo eziveliswayo. I-Magnesium hydroxide sisixhobo esithembisayo sokufunxa umlilo esingenandalo kwii-polymer-based composites. Njenge-aluminium hydroxide, isebenza ngokufunxa ubushushu ngokubola kobushushu kwaye ikhuphe amanzi, iyenza ingabi natyhefu, ingatshisi kakhulu, kwaye ibe nobuhlobo nokusingqongileyo, njengoko i-magnesium oxide ephumayo izinzile kwaye ayibangeli ungcoliseko lwesibini.

Nangona kunjalo, xa kuthelekiswa nezinto ezithintela ilangatye eziphilayo eziqulethe i-halogen, ukufumana isiphumo esifanayo sokuthintela ilangatye kufuna umlinganiselo wokuzalisa ongaphezulu kwama-50%. Ekubeni i-magnesium hydroxide ingekho kwindalo, umphezulu wayo awuhambelani kakuhle nee-polymer substrates. Umlinganiselo ophezulu wokuzalisa, ngaphandle kokuguqulwa komphezulu, uya kunciphisa iipropati zoomatshini zezinto ezidityanisiweyo. Ke ngoko, ukuguqulwa komphezulu kuyimfuneko ukuphucula ukuhambelana kwayo nee-polymer substrates, ukuqinisekisa ukuba iipropati zoomatshini zezinto ezizalisiweyo azichaphazeleki—okanye ziphuculwe kwezinye iinkalo.

Kuyo yonke inkqubo yokuthintela umlilo, i-magnesium hydroxide ayivelisi naziphi na izinto eziyingozi. Ngaphezu koko, iimveliso zayo zokubola zinokufunxa iigesi ezininzi ezinobuthi kunye nomsi oveliswa kukutsha kwerabha, iiplastiki kunye nezinye iipolymers. I-magnesium oxide esebenzayo ihlala ifunxa iintsalela ezinyibilikisiweyo ezitshisiweyo ngokupheleleyo, icima amalangatye ngokukhawuleza ngelixa isusa umsi kwaye ithintela ukuvuza kwe-melt. Yinto yesiqhelo ethintela umlilo ongekho ngokwemvelo.

Okwangoku, i-aluminium hydroxide isetyenziswa kakhulu eTshayina. Nangona kunjalo, njengoko amaqondo obushushu okucubungula i-polymer enyuka, i-aluminium hydroxide idla ngokubola, nto leyo enciphisa ukusebenza kwayo okubambezela ilangabi. Xa kuthelekiswa, i-magnesium hydroxide inezibonelelo ezilandelayo:

1. Ubushushu Obuphezulu Bokubola Kobushushu – I-Magnesium hydroxide iyabola kwi-340°C, engaphezulu kwe-100°C kune-aluminium hydroxide. Oku kuvumela amaqondo obushushu aphezulu okucubungula iplastiki, ukuphucula ukusebenza kakuhle kokukhupha, ukuphucula ukwenziwa kweplastiki, ukunciphisa ixesha lokubumba, kunye nokuqinisekisa ukukhanya okuphezulu komphezulu kunye neziphene ezimbalwa ngelixa kugcinwa amandla aqinileyo okuxobuka.
2. Ubungakanani beParticle obufanayo kunye nokuhambelana okuhle – Ukusasazwa kwayo ngokulinganayo kweparticle kuqinisekisa ukuhambelana okungcono nesubstrates, kunciphisa impembelelo kwiimpawu zoomatshini zemveliso.
3. Ukwenziwa Komqobo Wokukhusela – Emva kokuphelelwa ngamanzi emzimbeni ngexesha lokutsha, i-magnesium oxide ephumayo yinto enamandla aphezulu, engatshisi ubushushu esebenza njengomqobo wokukhusela, ihlukanisa amadangatye kunye neegesi ezinobuthi. I-magnesium hydroxide ikwathintela iigesi ze-acidic (SO₂, NOx, CO₂) eziveliswa ngexesha lokutsha kweplastiki.
4. Ukusebenza kakuhle kokubola kunye nokuncitshiswa komsi – Ibonisa amandla aqinileyo okubamba ilangatye kunye nokuncitshiswa komsi ngelixa ingarhawuzeli kangako izixhobo, ngaloo ndlela yandisa ubomi bomatshini.
5. Ixabiso Eliphantsi – I-Magnesium hydroxide flame retardant ixabisa isiqingatha se-aluminium hydroxide. Umthamo wayo wokuzalisa ophezulu unciphisa kakhulu iindleko zemveliso.
