Halogenated na Halogen-Yubusa Flame Retardant XPS

Ikibaho cya polystirene (XPS) ni ibikoresho bikoreshwa cyane mu kubaka insulasiyo, kandi ibikoresho byayo birinda umuriro ni ngombwa mu kubaka umutekano. Igishushanyo mbonera cya flame retardants ya XPS bisaba gutekereza cyane kubikorwa bya flame retardant, imikorere yo gutunganya, igiciro, nibidukikije. Hano hepfo ni igishushanyo kirambuye hamwe nibisobanuro bya flame retardant formulaire ya XPS, ikubiyemo ibisubizo byombi bya halogene na halogen-flame retardant ibisubizo.

1. Gushushanya Amahame ya XPS Flame Retardant formulaire

Ibice nyamukuru bigize XPS ni polystirene (PS), kandi guhindura flame retardant ihinduka bigerwaho cyane cyane wongeyeho flame retardants. Igishushanyo mbonera kigomba gukurikiza amahame akurikira:

• Umuriro mwinshi cyane: Kuzuza ibipimo bya flame retardant kubikoresho byubaka (urugero, GB 8624-2012).
• Gutunganya imikorere: Flame retardant ntigomba kugira ingaruka zikomeye kubikorwa byo kubira no kubumba XPS.
• Ibidukikije byangiza ibidukikije: Halogene idafite flame retardants igomba gushyirwa imbere kugirango yubahirize amabwiriza y’ibidukikije.
• Kugenzura ibiciro: Kugabanya ibiciro mugihe wujuje ibisabwa.

2. Halogenated Flame Retardant XPS

Halogenated flame retardants (urugero, bromine) ihagarika urunigi rwo gutwika irekura radicals ya halogen, itanga umuriro mwinshi ariko ikangiza ibidukikije nubuzima.

(1) Ibigize:

• Polystirene (PS): 100phr (base base)
• Bromined flame retardant: 10–20phr (urugero, hexabromocyclododecane (HBCD) cyangwa polystirene ya bromine)

• Amavuta: 1-2phr (urugero, calcium stearate, yongerera amazi gutunganya)
• Antioxidant: Igice cya 0.5–1 (urugero, 1010 cyangwa 168, birinda kwangirika mugihe cyo gutunganya)

(2) Uburyo bwo gutunganya:

• Premix PS resin, flame retardant, synergist, ikwirakwiza, amavuta, na antioxydeant kimwe.
• Ongeramo agent ifuro kandi ushonga-kuvanga muri extruder.
• Kugenzura ubushyuhe bwo gusohora kuri 180-220 ° C kugirango umenye neza ifuro.

(3) Ibiranga:

• Ibyiza: Flame retardant ikora neza, umubare wongeyeho, nigiciro gito.
• Ibibi: Irashobora kubyara imyuka yubumara (urugero, hydrogen bromide) mugihe cyo gutwikwa, bitera impungenge ibidukikije.

3. Halogen-Yubusa Flame Retardant XPS

Umuriro wa Halogene utagira umuriro (urugero, fosifore, ishingiye kuri azote, cyangwa hydroxide idafite ingufu) igera ku gucana umuriro binyuze mu kwinjiza ubushyuhe cyangwa gukora ibice bikingira, bitanga imikorere myiza y’ibidukikije.

(1) Ibigize:

• Polystirene (PS): 100phr (base base)
• Fosifore ishingiye kuri flame retardant: 10-15phr (urugero,ammonium polyphosifate (APP)cyangwa fosifore itukura)
• Azote ishingiye kuri flame retardant: 5-10phr (urugero, melamine cyanurate (MCA))
• Hydroxide idasanzwe: 20-30phr (urugero, hydroxide ya magnesium cyangwa hydroxide ya aluminium)
• Umukozi: 5-10phr (urugero, karuboni ya dioxyde cyangwa butane)
• Gutatana: 1-2phr (urugero, ibishashara bya polyethylene, biteza imbere)
• Amavuta: 1-2phr (urugero, zinc stearate, yongerera amazi gutunganya)
• Antioxidant: Igice cya 0.5–1 (urugero, 1010 cyangwa 168, birinda kwangirika mugihe cyo gutunganya)

(2) Uburyo bwo gutunganya:

• Premix PS resin, flame retardant, ikwirakwiza, amavuta, na antioxydeant kimwe.
• Ongeramo agent ifuro kandi ushonga-kuvanga muri extruder.
• Kugenzura ubushyuhe bwo gusohora kuri 180-210 ° C kugirango ubone ifuro ryinshi.

(3) Ibiranga:

• Ibyiza: Ibidukikije byangiza ibidukikije, nta myuka yubumara ikorwa mugihe cyo gutwikwa, yubahiriza amabwiriza y’ibidukikije.
• Ibibi: Flame retardant ikora neza, ingano yinyongera, irashobora kugira ingaruka kumikorere no gukora ifuro.

4. Ibyingenzi byingenzi mugushushanya

(1) Guhitamo Flame Retardant Guhitamo

• Halogenated flame retardants: Gukora neza ariko bitera ingaruka kubidukikije nubuzima.
• Halogen-flame retardants: Ibidukikije byangiza ibidukikije ariko bisaba amafaranga yinyongera.

(2) Gukoresha Synergiste

• Antimony trioxide: Gukorana hamwe na halogenated flame retardants kugirango uzamure cyane umuriro.
• Fosifore-azote ikorana: Muri sisitemu idafite halogene, fosifore na azote ishingiye kuri flame retardants irashobora gufatanya kunoza imikorere.

(3) Gutatana no gutunganywa

• Gutatana: Menya neza ko ikwirakwizwa rya flame retardants kugirango wirinde kwibanda cyane.
• Amavuta: Kunoza uburyo bwo gutunganya no kugabanya ibikoresho.

(4) Guhitamo abakozi benshi

• Ibikoresho bifata ifuro: Nka CO₂ cyangwa butane, ibidukikije bitangiza ingaruka nziza.
• Imiti ifata imiti: Nka azodicarbonamide (AC), gukora neza cyane ariko birashobora kubyara imyuka mibi.

(5) Antioxydants

Irinde kwangirika kwibintu mugihe cyo gutunganya no kuzamura ibicuruzwa bihamye.

5. Porogaramu zisanzwe

• Kubaka: Ikoreshwa mu rukuta, hejuru, no hasi.
• Ibikoresho bikonje: Gukingira ububiko bukonje hamwe nibinyabiziga bikonjesha.
• Indi mirima: Ibikoresho byo gushushanya, ibikoresho bitangiza amajwi, nibindi.

6. Ibyifuzo byo guhitamo neza

(1) Kunoza imikorere ya Flame Retardant

• Ikirimi cya flame retardants: Nka halogen-antimoni cyangwa fosifore-azote ikorana kugirango yongere umuriro.
• Nano flame retardants: Nka hydroxide ya nano magnesium cyangwa ibumba rya nano, kunoza imikorere mugihe ugabanya inyongeramusaruro.

(2) Kuzamura Ibikoresho bya mashini

• Abakozi bakomeye: Nka POE cyangwa EPDM, kunoza ubukana bwibintu no kurwanya ingaruka.
• Gushimangira abuzuza: Nka fibre yibirahure, kongera imbaraga no gukomera.

(3) Kugabanya ibiciro

• Hindura ibipimo bya flame retardant: Kugabanya imikoreshereze mugihe wujuje ibisabwa bya flame retardant.
• Hitamo ibikoresho bikoresha neza: Nkurugo cyangwa rwavanze flame retardants.

7. Ibidukikije nibisabwa

• Halogenated flame retardants: Bibujijwe namabwiriza nka RoHS na REACH; Koresha witonze.
• Halogen-flame retardants: Kurikiza amabwiriza y’ibidukikije kandi uhagararire ibizaza.

Incamake

Igishushanyo mbonera cya flame retardants ya XPS igomba kuba ishingiye kubintu byihariye bisabwa hamwe nibisabwa n'amategeko, ugahitamo hagati ya halogene cyangwa halogen idafite flame retardants. Halogenated flame retardants itanga umusaruro mwinshi ariko itera impungenge ibidukikije, mugihe halogen idafite flame retardants yangiza ibidukikije ariko bisaba amafaranga menshi yinyongera. Muguhindura uburyo hamwe nibikorwa, imikorere-yo hejuru, yangiza ibidukikije, hamwe nigiciro cyinshi cya flame-retardant XPS irashobora kubyazwa umusaruro kugirango inyubako zubakwe hamwe nizindi nzego.
