I-aluminiyam hydroxide powder ene-flame retardant, ukupheliswa komsi, ukuzaliswa kunye neminye imisebenzi emininzi, kunokuvelisa i-synergistic flame retardant effect kunye ne-phosphorus kunye nezinye izinto, luhlu olubanzi lweemveliso zeekhemikhali, ziye zaba yi-electronic, ikhemikhali, ikhebula, iiplastiki, i-rubber kunye namanye amashishini kwindawo ebalulekileyo yokukhusela indalo buthathaka. I-Aluminium hydroxide njenge-filler inorganic flame retardant, ukwenzela ukuba kufezekiswe umphumo ongcono we-flame retardant, isixa sokuzaliswa sidinga i-40%, ukuya kuthi ga kwi-60%, kodwa isixa esiphezulu sokuzaliswa asichaphazeli kakhulu kuphela iipropati ze-mechanical zemveliso, kunye ne-extrusion. kwaye iipropathi zokucubungula ziba mandundu. Ngoko ke, ukuguqulwa komphezulu kuyimfuneko.
Khetha izilungisi zomphezulu ezahlukeneyo kunye nezixa ezahlukeneyo zezilungisi zokulungiswa komphezulu omanzii-aluminiyam hydroxide. Ngokusebenzisa ixabiso le-oyile yokuxutywa kwe-aluminium hydroxide powder ngaphambi nangemva kokuguqulwa, iipropati ze-aluminium hydroxide powder eziguquliweyo zitshintshile ngokucacileyo, i-hydrophilicity kunye nexabiso lokufunxa ioli liye lancipha kakhulu, kwaye ukusabalalisa kwisigaba sezinto eziphilayo kwanda ngokucacileyo. Ukuguqulwa komphezulu kwakhona kunempembelelo kwiipropati ze-aluminium hydroxide composite system. Ukubuyiswa komlilo kunye nokuphucula indlela ye-aluminiyam hydroxide ephezulu esebenzayo yahlalutywa ngohlalutyo lwe-thermogravimetric kunye nokuskena i-electron microscopy. Ukuguqulwa komphezulu kunokuphucula kakhulu iipropati ezibanzi ze-aluminium hydroxide egcwele inkqubo ye-PVC. Iikhompawundi ezininzi zezinto eziphilayo zakhethwa ukuguqula umphezulu we-alumina hydroxide powder. Ngokuhlalutya ixabiso le-oyile yokufunxa, i-activation degree kunye nobukhulu be-particle ye powder modified, ukuguqulwa kwezinto eziphilayo kwenze ubungakanani be-particle ye-alumina hydroxide powder encinci. Indlela yokudibanisa imichiza endaweni yendlela yokwaleka ngokomzimba yendabuko inokuphucula ukuzinza kwe-dispersion kunye nokuhambelana kwe-nano-hydroxide flame retardant kwiipolymer eziphilayo.
Nokuba yeyiphi na indlela yokuguqulwa kwe-aluminium hydroxide, ungasebenzisa umatshini wokuguqula umphezulu womgubo wokusila inyosi, inkqubo yokuguqula incindi yobusi luhlobo lwenkqubo esebenzayo yokutshayela umoya, izinto ngokuhamba komoya kwinkqubo yokutshintsha iimpawu, ubuncinci bokuphatha amandla. ye-0.05 yeetoni / ngeyure, ubuninzi beetoni ezili-15 ngeyure.
