Kubisabwa bya flame retardant ya latex sponge, ibikurikira nisesengura rishingiye kubintu byinshi biriho (flaux aluminium hydroxide, zinc borate, aluminium hypophosphite, MCA) hamwe nibyifuzo byatanzwe:
I. Isesengura rya Flame iriho ikoreshwa
Hydroxide ya Aluminium (ATH)
Ibyiza:
- Ibidukikije byangiza ibidukikije, igiciro gito.
- Ikora binyuze muri endothermic decomposition no kurekura imyuka y'amazi, ikwiranye na sisitemu ya halogene.
Ibibi:
- Irasaba gupakira cyane (30-50 interuro) kugirango ikore neza, ishobora kugira ingaruka kuri sponge elastique nubucucike.
Ibisabwa:
- Bikwiranye na flame retardant formulaire.
- Basabwe guhuza hamwe na synergiste (urugero, zinc borate).
Zinc Borate
Ibyiza:
- Gukoresha flame retardant, byongera imikorere ya ATH.
- Guteza imbere char gushiraho no guhagarika umwotsi.
Ibibi:
- Imikorere mike iyo ikoreshejwe wenyine; bisaba guhuza nabandi barinda umuriro.
Ibisabwa:
- Basabwe nkumuhuza wa ATH cyangwa hypophosphite ya aluminium.
Aluminium Hypophosphite
Ibyiza:
- Byiza cyane, halogen-yubusa, gupakira hasi (interuro 10-20).
- Ubushyuhe bwiza bwumuriro, bukwiranye nibisabwa kugirango flame isubire inyuma.
Ibibi:
- Igiciro kinini.
- Guhuza na latex sisitemu ikeneye kugenzurwa.
Ibisabwa:
- Birakwiriye kurwego rwo hejuru rwo gucana umuriro (urugero, UL94 V-0).
- Irashobora gukoreshwa wenyine cyangwa mukomatanya.
MCA (Melamine Cyanurate)
Ibyiza:
- Azote ishingiye kuri flame retardant, ikuraho umwotsi.
Ibibi:
- Gukwirakwiza nabi.
- Birashobora kubangamira ifuro.
- Ubushyuhe bwo hejuru cyane (~ 300 ° C), budahuye nubushyuhe buke bwo gutunganya latex.
Ibisabwa:
- Ntabwo bisabwa nkibyingenzi; bisaba kwemeza ubushakashatsi.
II. Basabwe Gutegura no Gutanga ibitekerezo
Gutegura 1: ATH + Zinc Borate (Ihitamo ry'ubukungu)
Ibigize:
- Hydroxide ya Aluminium (ATH): 30-40 interuro
- Zinc Borate: 5-10 interuro
- Gutandukana (urugero, umukozi wo guhuza silane): 1-2 interuro (itezimbere gutandukana)
Ibiranga:
- Igiciro gito, cyangiza ibidukikije.
- Birakwiriye kubisabwa muri flame muri rusange (urugero, UL94 HF-1).
- Birashobora kugabanya gato kwihanganira sponge; Gukoresha ibirunga bikenewe.
Ifumbire ya 2: Aluminium Hypophosphite + Zinc Borate (Ihitamo-Ryinshi)
Ibigize:
- Aluminium Hypophosphite: 15-20 interuro
- Zinc Borate: 5-8 interuro
- Plastiseri (urugero, paraffine y'amazi): interuro 2-3 (itezimbere imikorere)
Ibiranga:
- Umuriro mwinshi wo kudindiza neza, gupakira bike.
- Birakwiriye kubintu byinshi bisabwa (urugero, gutwika vertical V-0).
- Guhuza aluminium hypophosphite hamwe na latex ikeneye kwipimisha.
Uburyo bwa 3: ATH + Aluminium Hypophosphite (Ihitamo Ryuzuye)
Ibigize:
- Hydroxide ya Aluminium: 20-30 interuro
- Aluminium Hypophosphite: 10-15 interuro
- Zinc Borate: 3-5 interuro
Ibiranga:
- Kuringaniza ibiciro nibikorwa.
- Kugabanya kwishingikiriza kumuriro umwe utinda, kugabanya ingaruka kumiterere yumubiri.
III. Ibitekerezo
Gutandukana:
- Imirase yumuriro igomba kuba hasi kuri ≤5μm kugirango birinde kugira ingaruka kumiterere.
- Mbere yo gutatanya muri latex cyangwa ibikoresho byihuta byo kuvanga birasabwa.
Uburyo bwo gukiza:
- Kugenzura ubushyuhe bukiza (mubisanzwe 110-130 ° C kuri latex) kugirango wirinde kwangirika imburagihe.
Kwipimisha Imikorere:
- Ibizamini by'ingenzi: Indangantego ya Oxygene (LOI), Gutwika Vertical (UL94), Ubucucike, Kwihangana.
- Niba flame retardancy idahagije, ongera buhoro buhoro aluminium hypophosphite cyangwa ATH.
IV. Ibyifuzo by'inyongera
Ikizamini cya MCA:
- Niba ugerageza, koresha interuro 5-10 mubice bito kugirango urebe ingaruka kuburinganire.
Ibyemezo by’ibidukikije:
- Menya neza ko umuriro watoranijwe wubahiriza RoHS / REACH kubyohereza hanze.
Imvange ihuza:
- Tekereza kongeramo bike bya nanoclay (interuro 2-3) kugirango wongere ingaruka za barrière.
