Sidee loo sameeyaa isbuunyo caato ah oo ololka celisa?

Shuruudaha dib u dhigista ololka ee isbuunyada cinjirka ah, kuwan soo socda waa falanqayn ku saleysan dhowr dab-demis oo jira (aluminium hydroxide, zinc borate, aluminium hypophosphite, MCA) oo ay la socdaan talooyinka qaabeynta:

I. Falanqaynta Codsiga Dabcinta Ololka Jirta

Aluminium Hydroxide (ATH)
Faa'iidooyinka:

• Deegaanka saaxiibtinimo, qiimo jaban.
• Waxay ka shaqeysaa burburka endothermic iyo sii deynta uumiga biyaha, oo ku habboon nidaamyada aan halogen-ka lahayn.

Khasaaraha:

• Waxay u baahan tahay culays sare (30-50 phr) waxtarka, taas oo saamayn karta barti iyo cufnaanta isbuunyada.

Codsiga:

• Ku habboon qaabaynta holac-dejinta aasaasiga ah.
• Lagu taliyay in lagu daro isku-duwaha (tusaale, borate zinc).

Zinc Borate
Faa'iidooyinka:

• Dib-u-celinta ololka is-dhexgalka, waxay kor u qaadaysaa waxtarka ATH.
• Waxay kor u qaadaa samaynta dhuxusha waxayna joojisaa qiiqa.

Khasaaraha:

• Waxtarka xaddidan marka keligiis la isticmaalo; waxay u baahan tahay isku darka ololka dib u dhigista.

Codsiga:

• Lagu taliyay sidii isku-dubarid ahaan ATH ama aluminium hypophosphite.

Aluminium Hypophosphite
Faa'iidooyinka:

• Aad u hufan, halogen-la'aan ah, rarayn hoose (10-20 phr).
• Degenaansho kulayl wanaagsan, oo ku habboon shuruudaha dib u dhigista ololka sare.

Khasaaraha:

• Qarash sare.
• Waafaqsanaanta nidaamyada cinjirka waxay u baahan tahay xaqiijin.

Codsiga:

• Ku habboon heerarka dib u dhacyada ololka sare (tusaale, UL94 V-0).
• Waxaa loo isticmaali karaa kaligiis ama isku darka.

MCA (Melamine Cyanurate)
Faa'iidooyinka:

• Dab-demiska Nitrogen-ku-salaysan, qiiq-dejinta.

Khasaaraha:

• Kala firdhinta liidata.
• Waxaa laga yaabaa inay farageliso xumbo-xumada.
• Heerkulka burburka sarreeya (~ 300°C), oo aan ku habboonayn habaynta cinjirka heerkulka hooseeya.

Codsiga:

• Laguma talinayo mudnaanta; waxay u baahan tahay xaqiijin tijaabo ah.

II. Qaababka lagu taliyay iyo soo jeedinta habraaca

Habka 1: ATH + Zinc Borate (Doorashada Dhaqaale)
Halabuurka:

• Aluminium Hydroxide (ATH): 30-40 phr
• Zinc Borate: 5-10 phr
• Kala firdhiya (tusaale, wakiilka isku xidhka silane): 1-2 phr (waxay wanaajisaa kala daadsanaanta)

Astaamaha:

• Qiimo jaban, deegaan ahaan u wanaagsan.
• Ku habboon shuruudaha dib u dhigista ololka guud (tusaale, UL94 HF-1).
• Waxa laga yaabaa inay yara yaraato adkeysiga isbuunyada; Hagaajinta vulcanization ayaa loo baahan yahay.

Habka 2: Aluminium Hypophosphite + Zinc Borate (Doorashada Waxtarka Sare)
Halabuurka:

• Aluminium Hypophosphite: 15-20 phr
• Zinc Borate: 5-8 phr
• Balaastiijiyaha (tusaale, paraffin dareere): 2-3 phr (waxay wanaajisaa habsocodka)

Astaamaha:

• Waxtarka dib u dhigista ololka sare, rarista hoose.
• Ku habboon xaaladaha baahida sare (tusaale, gubashada tooska ah ee V-0).
• Waafaqsanaanta aluminium hypophosphite iyo baaritaanka baahida cinjirka

Qaabka 3: ATH + Aluminium Hypophosphite (Doorashada Isku Dheedhan)
Halabuurka:

• Aluminium Hydroxide: 20-30 phr
• Aluminium Hypophosphite: 10-15 phr
• Zinc Borate: 3-5 phr

Astaamaha:

• Isku dheelitirka qiimaha iyo waxqabadka.
• Waxay yaraynaysaa ku tiirsanaanta hal olol oo dib u dhigista, iyadoo yaraynaysa saamaynta ay ku leedahay sifooyinka jidhka.

III. Tixgelinta Habraaca

Kala firdhinta:

• Dab-celiyayaasha ololku waa inay dhulka dhigaan ilaa ≤5μm si looga fogaado inay saameeyaan dhismaha xumbo.
• Horey ugu firidhsanaanta cinjirka ama qalabka isku dhafka xawaaraha sare ayaa lagula talinayaa.

Xaaladaha Daawaynta:

• Xakamee heerkulka daweynta (sida caadiga ah 110-130 ° C ee cinjirka) si looga hortago burburka hore ee ololka.

Tijaabada Waxqabadka:

• Tijaabooyinka muhiimka ah: Ogsajiinta Ogsajiinta (LOI), Gubashada Toosan (UL94), Cufnaanta, Adkeysiga.
• Haddii daahitaanka ololku aanu ku filnayn, si tartiib ah u kordhi aluminium hypophosphite ama saamiga ATH.

IV. Talooyin Dheeraad ah

Imtixaanka MCA:

• Haddii la tijaabinayo, isticmaal 5-10 phr dufcad yar si aad u aragto saamaynta ay ku yeelanayso isku midnimada xumbo

Shahaadooyinka Deegaanka:

• Hubi in dab-demisyada la doortay ay u hoggaansamaan RoHS/REACH dhoofinta.

Isku-dhafka Isku-dhafka ah:

• Tixgeli inaad ku darto xaddi yar oo nanoclay ah (2-3 phr) si aad kor ugu qaaddo saamaynta xannibaadda.
