Aluminium Hypophosphite iyo MCA ee tuubooyinka kulaylka-yaraynta EVA

Markaad isticmaalayso aluminium hypophosphite, MCA (melamine cyanurate), iyo magnesium hydroxide sida ololka dab-demiska ee EVA tuubooyinka kulaylka-yar, qiyaasta qiyaasta iyo tilmaamaha hagaajinta waa sida soo socota:

1. Qiyaasta lagu taliyey ee Dib-u-celinta Ololka

Aluminium Hypophosphite

Qiyaasta:5% -10%
Shaqada:Dib u dhiga ololka oo aad waxtar u leh, waxay kor u qaadaa samaynta dhuxusha, waxayna yaraynaysaa heerka sii deynta kulaylka.
Fiiro gaar ah:Qadarka xad dhaafka ah waxa uu wiiqi karaa dabacsanaanta shay; Waxyaalaha isku-dhafka ah waa in lagu daraa hagaajinta.

MCA (Melamine Cyanurate)

Qiyaasta:10% -15%
Shaqada:Dib-u-dhigista ololka-waji-gaas, nuuga kulaylka oo sii daaya gaasas aan shaqaynayn (tusaale, NH₃), isku-duubnida aluminium hypophosphite si kor loogu qaado dib u dhaca ololka.
Fiiro gaar ah:Culayska xad dhaafka ahi waxa uu keeni karaa tahriib; waafaqsanaanta EVA waa in la hubiyaa.

Magnesium Hydroxide (Mg(OH)₂)

Qiyaasta:20%-30%
Shaqada:Kala-baxa Endothermic wuxuu sii daayaa uumiga biyaha, wuxuu milo gaasaha ololaya wuxuuna xakameynayaa qiiqa.
Fiiro gaar ah:Culayska sarreeya ayaa laga yaabaa inuu yareeyo sifooyinka farsamada; wax ka beddelka dusha sare ayaa lagula talinayaa si loo hagaajiyo kala firdhisanaanta.

2. Talooyinka Hagaajinta Habaynta

Wadarta Nidaamka Dabcinta Ololka:Waa in aanu dhaafin 50% si loo miisaamo dib u dhaca ololka iyo socodsiinta (tusaale, dabacsanaanta, heerka yaraanta).
Saamaynta Isku-dhafka:
Aluminium hypophosphite iyo MCA waxay yarayn karaan qiyaasaha gaarka ah (tusaale, 8% aluminium hypophosphite + 12% MCA).
Magnesium hydroxide waxay dhamaystiraysaa dib u dhaca ololka iyada oo loo marayo saamaynta endothermic iyadoo yaraynaysa qiiqa.
Daaweynta Dusha sare:Waxyaalaha isku xidha ee Silane waxay wanaajin karaan kala firdhisanaanta iyo isku xidhka dhexda ee magnesium hydroxide.
Waxyaalaha Kaaliyaha ah:
Ku dar 2%-5% wakiilada samaynta char (tusaale, pentaerythritol) si loo hagaajiyo xasiloonida lakabka char.
Ku dar xaddi yar oo balaastiisteyaal ah (tusaale, saliid soybean ah epoxidized) si loo magdhabo luminta dabacsanaanta.

3. Tilmaamaha Xaqiijinta Waxqabadka

Tijaabada Dib u Dhaca Ololka:
UL94 tijaabada gubashada tooska ah (bartilmaameedka: V-0).
Xaddidaadda Tusaha Ogsajiinta (LOI>28%).
Guryaha Makaanikada:
Qiimee xoogga xajinta iyo dhererka nasashada si loo hubiyo in dabacsanaantu ay buuxiso shuruudaha codsiga.
Geedi socodka:
La soco Tusaha socodka qulqulka dhalaalka (MFI) si aad uga fogaato dhibaatooyinka habaynta sababtoo ah buuxinta xad dhaafka ah.

4. Qiimaha iyo Tixgelinta Deegaanka

Hadhaaga Qiimaha:Aluminium hypophosphite waa qaali; qiyaasteeda waa la dhimi karaa (oo lagu daray MCA) si loo xakameeyo kharashyada.
Saaxiibtinimada deegaanka:Magnesium hydroxide waa mid aan sun ahayn oo qiiq-cabbir ah, taas oo ka dhigaysa mid ku habboon codsiyada deegaanka-saaxiibtinimo.

Samaynta Tusaalaha (Tixraac kaliya):
