Adeegsiga:
- Ku habboon qaacidooyinka aasaasiga ah ee ka hortagga dabka.
- Waxaa lagugula talinayaa in lagu daro synergists (tusaale ahaan, zinc borate).
Zinc Borate
Faa'iidooyinka:
- Dawada dabka ee isku dhafan, waxay xoojisaa waxtarka ATH.
- Waxay kor u qaadaa sameynta walxaha qarxa waxayna xakameysaa qiiqa.
Qasaarooyinka:
- Waxtar xaddidan marka kaligaa la isticmaalo; waxay u baahan tahay isku-darka waxyaabaha kale ee joojiya ololka.
Adeegsiga:
- Waxaa lagu taliyay inay noqoto isku-dubaridka ATH ama aluminium hypophosphite.
Aluminium Hypophosphite
Faa'iidooyinka:
- Waxtar badan, aan halogen lahayn, rarid yar (10-20 phr).
- Xasillooni kuleyl oo wanaagsan, oo ku habboon shuruudaha dib u dhigista ololka sare.
Qasaarooyinka:
- Kharash sare.
- Ku habboonaanta nidaamyada latex waxay u baahan tahay xaqiijin.
Adeegsiga:
- Ku habboon heerarka sare ee dib u dhigista ololka (tusaale ahaan, UL94 V-0).
- Waxaa loo isticmaali karaa kaligiis ama isku darka.
MCA (Melamine Cyanurate)
Faa'iidooyinka:
- Wax ka celiya ololka ku salaysan Nitrogen-ka, oo joojiya qiiqa.
Qasaarooyinka:
- Kala firdhis la'aan liidata.
- Waxay faragelin kartaa xumbo.
- Heerkulka kala-baxa sare (~300°C), oo aan la jaanqaadin habka loo yaqaan 'latex' oo heerkul hooseeya.
Adeegsiga:
- Laguma talinayo in mudnaanta la siiyo; waxay u baahan tahay xaqiijin tijaabo ah.
II. Qaacidooyinka lagu taliyay iyo Talooyinka Habka
Qaaciddada 1aad: ATH + Zinc Borate (Ikhtiyaar Dhaqaale)
Halabuurka:
- Aluminium Haydrooksaydh (ATH): 30-40 hr
- Zinc Borate: 5-10 hr
- Kala-bixiyaha (tusaale ahaan, wakiilka isku xidhka silane): 1-2 phr (waxay hagaajisaa kala-firdhinta)
Astaamaha:
- Qiimo jaban, deegaan ahaanna u wanaagsan.
- Ku habboon shuruudaha guud ee dib u dhigista ololka (tusaale ahaan, UL94 HF-1).
- Waxaa laga yaabaa inay si yar u yareyso adkeysiga isbuunyada; Hagaajinta Vulcanization-ka ayaa loo baahan yahay.
Qaab-dhismeedka 2: Aluminium Hypophosphite + Zinc Borate (Ikhtiyaar Waxtar Sare leh)
Halabuurka:
- Aluminium Hypophosphite: 15-20 hr
- Zinc Borate: 5-8 hr
- Balaastig-sameeye (tusaale ahaan, paraffin dareere ah): 2-3 phr (waxay hagaajisaa habka wax-soo-saarka)
Astaamaha:
- Waxtarka dib-u-dhaca ololka sare, rarid yar.
- Ku habboon xaaladaha baahida sare leh (tusaale ahaan, gubashada toosan V-0).
- Isku-waafajinta hypophosphite-ka aluminiumka iyo latex-ka waxay u baahan tahay tijaabin.
Qaab-dhismeedka 3: ATH + Aluminium Hypophosphite (Ikhtiyaar Dheelitir ah)
Halabuurka:
- Aluminium Haydrooksaydh: 20-30 hr
- Aluminium Hypophosphite: 10-15 hr
- Zinc Borate: 3-5 hr
Astaamaha:
- Waxay dheellitirtaa kharashka iyo waxqabadka.
- Waxay yareysaa ku tiirsanaanta hal qalab oo dab-damiya, taasoo yareyneysa saameynta ay ku leedahay sifooyinka jirka.
III. Tixgelinta Habka
Firdhisanaan:
- Waxyaabaha dabka celiya waa in la burburiyaa ilaa ≤5μm si looga fogaado inay saameeyaan qaab-dhismeedka xumbo.
- Waxaa lagula talinayaa in qalabka isku-darka ee latex ama qalabka isku-darka xawaaraha sare leh lagu kala firdhiyo kahor.
Xaaladaha Daaweynta:
- Xakamee heerkulka bogsashada (badanaa 110-130°C oo loogu talagalay latex) si looga hortago burburka degdega ah ee walxaha ka hortagaya ololka.
Tijaabada Waxqabadka:
- Tijaabooyinka Muhiimka ah: Tusmada Ogsajiinta (LOI), Gubashada Toosan (UL94), Cufnaanta, Adkeysiga.
- Haddii dib-u-celinta ololku aysan ku filnayn, si tartiib tartiib ah u kordhi saamiga aluminium hypophosphite ama ATH.
IV. Talooyin Dheeraad ah
Baaritaanka MCA:
- Haddii aad tijaabinayso, isticmaal 5-10 phr qaybo yaryar si aad u aragto saameynta ay ku leedahay isku-dhafka xumbo.
Shahaadooyinka Deegaanka:
- Hubi in walxaha dab-damiska ee la xushay ay u hoggaansamaan RoHS/REACH si loo dhoofiyo.
Isku-darka Isku-dhafan:
- Ka fikir inaad ku darto xaddi yar oo nanoclay ah (2-3 phr) si aad u xoojiso saameynta caqabadaha char.
