Mu myaka yashize, hagiye hagaragara impungenge z’ibidukikije n’ubuzima biterwa na halogene ishingiye ku muriro ukoreshwa muri plastiki. Nkigisubizo, retardants itari halogen yamenyekanye cyane kubera umutekano wabo kandi urambye.
Halogene idafite flame retardants ikora muguhagarika inzira yo gutwika ibaho mugihe plastiki ihuye numuriro.
1.Babigeraho muburyo bwumubiri na chimique bibangamira imyuka yaka yasohotse mugihe cyo gutwikwa. Bumwe mu buryo busanzwe ni uburyo bwo gukora karubone irinda hejuru ya plastiki.
2. Iyi myuka itera inzitizi hagati ya plastike n'umuriro, bityo bikadindiza ikwirakwizwa ry'umuriro.
3. Imirasire ya halogene idafite umuriro irabora kandi ikora urwego ruhamye rwa karubone, izwi nka char, ikora nkinzitizi yumubiri, ikabuza gukomeza kurekura imyuka yaka umuriro.
4. Byongeye kandi, halogen idafite flame retardants irashobora kugabanya imyuka yaka mukoresheje ionizing no gufata radicals yubusa hamwe nibice byaka umuriro. Iyi myitwarire isenya neza urunigi rwo gutwikwa, bikagabanya ubukana bwumuriro.
Ammonium polyphosphate ni fosifore-azote halogene idafite flame retardant. Ifite flame retardant imikorere muri plastiki ifite uburozi nibidukikije.
Gukoresha plastiki
Plastike ya flame retardant nka FR PP, FR PE, FR PA, FR PET, FR PBT nibindi bikoreshwa cyane mubikorwa byinganda zitwara ibinyabiziga imbere yimodoka, nkibibaho, imbaho, inzugi ziciriritse, inzugi zamashanyarazi, insinga z'amashanyarazi, ibyuma byumuriro, amashanyarazi, hamwe no gutwara amazi, imiyoboro ya gaze.
Flame retardant standard (UL94)
UL 94 ni plastike yaka umuriro yasohowe na Laboratoire ya Underwriters (USA). Igipimo gishyira mubikorwa bya plastiki ukurikije uburyo bitwika mubyerekezo bitandukanye hamwe nubunini bwigice kuva kumuriro wo hasi cyane kugeza kuri flame-retardant mubyiciro bitandatu bitandukanye.
| UL 94 Urutonde | Ibisobanuro by'Urutonde |
| V-2 | Gutwika bihagarara mumasegonda 30 kuruhande rwemerera ibitonyanga bya plastike ihagaze. |
| V-1 | Gutwika bihagarara mumasegonda 30 kumurongo uhagaritse kwemerera ibitonyanga bya plastiki bitaka. |
| V-0 | Gutwika bihagarara mumasegonda 10 kumurongo uhagaritse kwemerera ibitonyanga bya plastiki bitaka. |
