Sannadihii ugu dambeeyay, waxaa jiray walaac sii kordhaya oo ku saabsan khataraha deegaanka iyo caafimaadka ee ka dhasha aaladaha dab-damiska ee ku salaysan halogen ee loo isticmaalo balaastikada. Natiijo ahaan, aaladaha dab-damiska ee aan halogen ahayn ayaa caan noqday sababtoo ah sifooyinkooda ammaan ah oo waara.
Dab-damiyayaasha dabka ee aan halogen-ka lahayn waxay shaqeeyaan iyagoo carqaladeynaya hababka gubashada ee dhaca marka balaastikada la kulmo dabka.
1. Waxay tan ku gaaraan iyagoo si jireed iyo kiimiko ah u faragelinaya gaasaska guban kara ee la sii daayo inta lagu jiro gubashada. Mid ka mid ah hababka caadiga ah waa sameynta lakab kaarboon oo ilaalin ah oo ku yaal dusha sare ee balaastigga.
2. Marka ay kulayl la kulmaan, aaladaha dab-damiska ee aan halogen lahayn waxay maraan falgal kiimiko ah, kaas oo sii daaya biyo ama gaasas kale oo aan guban karin. Gaasaskani waxay abuuraan caqabad u dhaxaysa balaastikada iyo ololka, sidaas darteedna waxay hoos u dhigaan faafitaanka dabka.
3. Kuwa dabka ka celiya ee aan halogen lahayn way burburaan waxayna sameeyaan lakab kaarboonaysan oo deggan, oo loo yaqaan char, kaas oo u shaqeeya sidii caqabad jireed, taasoo ka hortagaysa sii deynta sii deynta gaasaska guban kara.
4. Intaa waxaa dheer, dab-damiyayaasha aan halogen-ka lahayn waxay khafiifin karaan gaasaska guban kara iyagoo ion-ka gelinaya oo qabsanaya xagjirrada xorta ah iyo qaybaha ololka leh ee isbeddelaya. Falgalkani si wax ku ool ah ayuu u jebiyaa falgalka silsiladda gubashada, isagoo sii yareynaya xoogga dabka.
Ammonium polyphosphate waa dab-celiye aan lahayn fosfooraska-nitrogen-ka. Waxay leedahay waxqabad sare oo dab-celiye ah oo ku jira balaastikada oo aan sun ahayn oo leh astaamo deegaan.
Codsiga Bacaha
Balaastikada dab-damiska sida FR PP, FR PE, FR PA, FR PET, FR PBT iyo wixii la mid ah ayaa si caadi ah loogu isticmaalaa warshadaha baabuurta gudaha baabuurta, sida dashboard-yada, albaabada albaabada, qaybaha kuraasta, meelaha korontada lagu xiro, saxaaradaha fiilooyinka, muraayadaha korontada ee ka hortagga dabka, qalabka wax lagu beddelo, meelaha korontada lagu xiro, iyo tuubooyinka biyaha, gaaska lagu qaado.
Heerka daminta ololka (UL94)
UL 94 waa halbeeg gubasho balaastig ah oo ay soo saartay Underwriters Laboratories (USA). Heerku wuxuu u kala saaraa balaastikada iyadoo loo eegayo sida ay u gubaan jihooyin kala duwan iyo dhumucda qaybaha laga bilaabo kan ugu hooseeya ee ololka celiya ilaa kan ugu badan ee ololka celiya lix nooc oo kala duwan.
| Qiimaynta UL 94 | Qeexitaanka Qiimaynta |
| V-2 | Gubashada waxay joogsanaysaa 30 ilbiriqsi gudahood qayb ka mid ah taasoo u oggolaanaysa dhibco balaastig ah oo toosan oo guban kara. |
| V-1 | Gubashada waxay joogsanaysaa 30 ilbiriqsi gudahood qayb toosan taasoo u oggolaanaysa dhibco balaastig ah oo aan ololayn. |
| V-0 | Gubashada waxay joogsanaysaa 10 ilbiriqsi gudahood qayb toosan taasoo u oggolaanaysa dhibco balaastig ah oo aan ololayn. |
