Aluminium Hypophosphite iyo MCA oo ah qalab dab-damiya oo loogu talagalay Tuubada Kuleylka-Yaraynta EVA

Marka la isticmaalayo aluminium hypophosphite, MCA (melamine cyanurate), iyo magnesium hydroxide sidii wax ka dhiga ololka tuubooyinka kulaylka yareeya ee EVA, qiyaasta lagu taliyay iyo tilmaamaha hagaajinta waa sidan soo socota:

1. Qiyaasta lagu taliyay ee ka hortagga ololka

Aluminium Hypophosphite

Qiyaasta:5%–10%
Shaqada:Waxtar badan oo ka hortagta ololka, waxay kor u qaadaa sameynta dab-shidka, waxayna yareysaa heerka sii deynta kulaylka.
Fiiro gaar ah:Xaddi badan ayaa laga yaabaa inay wax u dhimaan dabacsanaanta agabka; waa in lagu daraa walxaha isku-dhafan si loo hagaajiyo.

MCA (Melamine Cyanurate)

Qiyaasta:10%–15%
Shaqada:Qalabka dab-damiska ee wejiga gaaska, wuxuu nuugaa kulaylka wuxuuna sii daayaa gaasaska aan firfircoonayn (tusaale ahaan, NH₃), isagoo la shaqeynaya aluminium hypophosphite si kor loogu qaado dabacsanaanta dabka.
Fiiro gaar ah:Culayska xad-dhaafka ah wuxuu sababi karaa socdaalka; waa in la hubiyaa in la waafajiyo EVA.

Magnesium Haydrooksaydh (Mg(OH)₂)

Qiyaasta:20%–30%
Shaqada:Kala-baxa endothermic wuxuu sii daayaa uumiga biyaha, wuxuu qasayaa gaasaska ololaya iyo wuxuu caburiyaa qiiqa.
Fiiro gaar ah:Rarka badan wuxuu yareyn karaa sifooyinka farsamada; wax ka beddelka dusha sare ayaa lagu talinayaa si loo hagaajiyo kala firdhinta.

2. Talooyinka Hagaajinta Qaab-dhismeedka

Nidaamka Dabar-goynta Ololka oo Dhan:Waa inaysan dhaafin 50% si loo dheellitiro dib-u-dhaca ololka iyo hab-socodsiinta (tusaale ahaan, dabacsanaan, heerka yaraynta).
Saamaynta Wadajirka ah:
Aluminium hypophosphite iyo MCA waxay yareyn karaan qiyaasta shaqsiga ah (tusaale ahaan, 8% aluminium hypophosphite + 12% MCA).
Magnesium hydroxide wuxuu dhameystiraa dib-u-dhaca ololka iyada oo loo marayo saameynta endothermic iyadoo la yareynayo qiiqa.
Daaweynta Dusha Sare:Wakiilada isku xidhka Silane waxay kor u qaadi karaan kala firdhinta iyo isku xidhka indhaha ee magnesium hydroxide.
Waxyaabaha lagu daro ee Caawinta leh:
Ku dar 2%–5% walxaha sameeya character-ka (tusaale ahaan, pentaerythritol) si loo hagaajiyo xasilloonida lakabka char.
Ku dar xaddi yar oo balaastig ah (tusaale ahaan, saliidda soybean-ka ee epoxidized) si aad u magdhabto dabacsanaanta lumitaanka.

3. Tilmaamaha Xaqiijinta Waxqabadka

Tijaabada Ka-hortagga Ololka:
Tijaabada gubashada toosan ee UL94 (bartilmaameedka: V-0).
Xaddidaadda Tusmada Ogsajiinta (LOI >28%).
Sifooyinka Farsamada:
Qiimee xoogga jiidista iyo dheereynta marka la nasto si loo hubiyo in dabacsanaantu ay buuxiso shuruudaha codsiga.
Hawl-socodsiin:
La soco Tusmada Socodka Dhalaalka (MFI) si looga fogaado dhibaatooyinka habaynta oo ay ugu wacan tahay buuxinta xad-dhaafka ah.

4. Qiimaha iyo Tixgelinta Deegaanka

Hadhaaga Kharashka:Aluminium hypophosphite waa qaali; qiyaasteeda waa la dhimi karaa (oo lagu dari karaa MCA) si loo xakameeyo kharashyada.
Saaxiibtinimada Deegaanka:Magnesium hydroxide ma aha sun iyo xakameeye qiiqa, taasoo ka dhigaysa mid ku habboon isticmaalka deegaanka u fiican.

Tusaalaha Qaabaynta (tixraac ahaan oo keliya):
