Dib-u-celinta ololka-free Halogen-ka ayaa door muhiim ah ka ciyaara goobta dab-demiska dabka.Marka ay sii korodho wacyiga dadka ee ilaalinta deegaanka, dab-demiyayaashii dhaqanka ee halogen ka kooban ayaa si isa soo taraysa loo bedelayaa.Dib-u-celinta ololka aan halogen-ka lahayn waa isku-dhisyo aan ku jirin curiyeyaasha halogen sida chlorine iyo bromine.Adeegsigoodu wuxuu leeyahay faa'iidooyin badan oo dib u dhaca holaca dharka.Waqtigan xaadirka ah, dhowr dab-deceyaal aan halogen-la'aan ahayn ayaa si weyn loogu isticmaalaa goobta dab-demiska dabka.Tusaalooyinka wakiilada waxaa ka mid ah: ammonium polyphosphate (APP), copolycyanurate (CP), aluminium hydroxide (ATH), nitrogen-phosphorus flame retardant (HNF), iwm. sidoo kale waxay soo saartaa falcelin kiimikaad oo joojisa gubashada heerkulka sare, si looga hortago fiditaanka dabka.Xoog gaar ah waa in la saaro ammonium polyphosphate (APP).Sida caadiga ah loo isticmaalo dib-u-dejinta olol-ka-la'aanta halogen, APP waxay leedahay awoodo dib-u-dhigis holac aad u wanaagsan.Dharka, APP waxay si kiimiko ah u nuugi kartaa kulaylka wayna dumin kartaa si ay u samaysato lakabka fidinta fosfatetada ololka, kaas oo si wax ku ool ah u xannibaya wareejinta ogsijiinta iyo kulaylka kana hortagaysa fiditaanka gubashada.Isla mar ahaantaana, APP waxay sidoo kale kor u qaadi kartaa falcelinta kaarboonaysiinta ee dharka waxayna dhalin kartaa lakab kaarboon cufan, taasoo sii wanajinaysa waxqabadka dabci ee marada.Tani waxay ka dhigaysaa APP mid ka mid ah kuwa ugu caansan ee dib u dhiga ololka halogen-la'aanta ee goobta dib u dhaca ololka dharka.Marka la soo koobo, dab-demiska aan halogen-ka lahayn ayaa door muhiim ah ka ciyaara goobta dab-demiska dabka.Adigoo isticmaalaya dab-celiyayaal aan halogen lahayn oo wakiil ka ah sida ammonium polyphosphate, dharku waxay gaadhi karaan saameyn wanaagsan oo dib-u-dhigista ololka waxayna wanaajisaa badbaadada dabka.Horumarka joogtada ah ee tignoolajiyada, waxaa la aaminsan yahay in dab-demiska aan halogen-la'aanta ahi uu door muhiim ah ka ciyaari doono dib u dhaca dabka mustaqbalka.
