Samaynta XPS ololka Halogenated iyo Halogen-Free Flame Retardant

looxa polystyrene extruded (XPS) waa shay si weyn loogu isticmaalo dhismaha dahaarka, iyo hantidiisa dib u olol ayaa muhiim u ah dhismaha ammaanka. Nakhshadeynta naqshadeeyayaasha ololka ee XPS waxay u baahan tahay tixgalin dhamaystiran ee hufnaanta retardant ololka, habaynta, kharashka, iyo shuruudaha deegaanka. Hoos waxa ah nakhshad tafatiran iyo sharraxaadda hababka dib-u-dhigista ololka ee XPS, oo daboolaya labadaba xalalka dib-u-dhigista ololka halogenated iyo halogen-la'aanta.

1. Mabaadi'da Naqshadeynta ee Hababka Dib u Celinta Ololka XPS

Qaybta ugu muhiimsan ee XPS waa polystyrene (PS), iyo wax ka beddelkeeda ololka waxa ugu horrayn lagu gaaraa iyadoo lagu darayo dib-u-dhigeyaasha ololka. Naqshadaynta qaabaynta waa in ay raacdaa mabaadi'da soo socota:

• Dib u dhigista ololka sareLa kulan heerarka dib u dhigista ololka ee qalabka dhismaha (tusaale, GB 8624-2012).
• Hagaajinta waxqabadka: Dab-demiska ololku waa in aanu si weyn u saamayn xumbo-samaynta iyo hab-samaynta XPS.
• Saaxiibtinimada deegaanka: Dabaasha holac la'aanta halogen waa in mudnaanta la siiyaa si ay ugu hoggaansamaan xeerarka deegaanka.
• Xakamaynta kharashka: Yaree kharashyada marka aad buuxinayso shuruudaha waxqabadka.

2. Samaynta Ololka Halogenated ee XPS

Dib-u-celiyayaasha ololka halogenaysan (tusaale, brominated) waxay joojiyaan falcelinta silsiladda gubashada iyagoo siidaaya xag-jirayaasha halogen, iyagoo siinaya waxtarka dabci sare laakiin keenaya khataro deegaan iyo caafimaad.

(1) Qaabaynta:

• Antioxidant: 0.5-1 qayb (tusaale, 1010 ama 168, waxay ka hortagtaa hoos u dhaca inta lagu jiro habaynta)

(2) Habka habaynta:

• Premix PS resin, olol retardant, synergist, kala firdhiye, saliidayn, iyo antioxidant isku mid ah.
• Ku dar wakiilka xumbo-sameynta oo dhalaali-ku walaaq gudaha dibadda.
• Xakamee heerkulka ka saarista 180-220 ° C si aad u hubiso xumbo sax ah iyo qaabaynta.

(3) Astaamaha:

• Faa'iidooyinka: Hufnaanta dab-demiska sare, qadar yar oo lagu daro, iyo qiimo jaban.
• KhasaaroWaxaa laga yaabaa inay soo saaraan gaas sun ah (tusaale, hydrogen bromide) inta lagu jiro gubashada, taasoo keenaysa walaac deegaan.

3. Samaynta XPS ololka Halogen-free

Halogen-free olol retardants (tusaale, fosfooraska ku salaysan, nitrogen-ku salaysan, ama hydroxides inorganic) waxay ku gaadhaan dib u dhac ololka iyada oo la nuugayo kulaylka ama samaynta lakabyo ilaalin ah, oo bixiya waxqabad deegaan oo wanaagsan.

(1) Qaabaynta:

• Polystyrene (PS): 100phr (resin sal)
• Fosfooraska ku salaysan ololka: 10-15 saac (tusaale,ammonium polyphosphate (APP)ama fosfooraska cas)
• Dab-demiska Nitrogen-ku-salaysan: 5-10phr (tusaale, melamine cyanurate (MCA))
• Hydroxide aan organic: 20-30phr (tusaale, magnesium hydroxide ama aluminium hydroxide)
• Wakiilka xumbo: 5-10ph (tusaale, carbon dioxide ama butane)
• Kala firdhisan: 1-2phr (tusaale, polyetylen wax, waxay hagaajisaa kala firdhisanaanta)
• Saliid: 1-2phr (tusaale, zinc stearate, waxay kordhisaa dareeraha habaynta)
• Antioxidant: 0.5-1 qayb (tusaale, 1010 ama 168, waxay ka hortagtaa hoos u dhaca inta lagu jiro habaynta)

(2) Habka habaynta:

• Premix PS resin, olol retardant, kala firdhiya, saliid, iyo antioxidant isku mid ah.
• Ku dar wakiilka xumbo-sameynta oo dhalaali-ku walaaq gudaha dibadda.
• Xakamee heerkulka extrusion heerkul ah 180-210 ° C si aad u hubiso xumbo sax ah iyo qaabaynta.

(3) Astaamaha:

• Faa'iidooyinka: Deegaanka saaxiibtinimo leh, ma jiraan gaas sun ah oo soo baxa inta lagu jiro gubashada, u hoggaansan xeerarka deegaanka.
• Khasaaro: Hufnaanta hoos u dhigista ololka, xaddi badan oo lagu daro, waxay saameyn kartaa sifooyinka farsamada iyo waxqabadka xumbo.

4. Tixgelinta Muhiimka ah ee Nakhshadeynta

Soo koobid

Naqshadeynta qaabeynta ololayaasha ee XPS waa in ay ku saleysnaadaan xaalado gaar ah oo codsi ah iyo shuruudaha sharciyeed, doorashada inta u dhexeysa dab-celiyayaasha halogenated ama halogen-free. Dib-u-celinta ololka halogenated waxay bixiyaan waxtar sare laakiin waxay keenaan walaac deegaanka, halka ololka aan halogen-ka lahayn dib-u-dhacyada deegaanka ay aad ugu saaxiibtinimo badan yihiin laakiin waxay u baahan yihiin xaddi dheeri ah. Iyada oo la wanaajinayo qaababka iyo hababka, waxqabadka sare, deegaanka-saaxiibtinimada leh, iyo ololka-dejinta kharash-ku-oolka ah ee XPS ayaa la soo saari karaa si loo daboolo baahiyaha dhismaha dahaarka iyo meelaha kale.
