Kulowetsa antimony trioxide/aluminium hydroxide retardant system ndi aluminium hypophosphite/zinc borate

Pa pempho la kasitomala kuti alowe m'malo mwa antimony trioxide/aluminium hydroxide flame retardant system ndi aluminium hypophosphite/zinc borate, zotsatirazi ndi dongosolo laukadaulo lokhazikitsa ndi mfundo zazikuluzikulu:

I. Mapangidwe Apamwamba Opanga Kachitidwe

1. Dynamic Ratio Adjustment Model

• Base RationAluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar chiŵerengero 1.2:1)
• High Flame Retardancy Demand: AHP 15% + ZB 5% (LOI ikhoza kufika 35%)
• Njira Yotsika mtengo: AHP 9% + ZB 9% (Kugwiritsa ntchito mtengo wa ZB, kumachepetsa mtengo ndi 15%)

1. Synergist Combination Solutions

• Mtundu Wautsi Wautsi: Onjezani 2% zinc molybdate + 1% nano-kaolin (kuchuluka kwa utsi kuchepetsedwa ndi 40%)
• Mtundu Wowonjezera: Onjezani 3% boehmite yosinthidwa pamwamba (mphamvu yosinthika idakwera ndi 20%)
• Mtundu Wolimbana ndi NyengoOnjezani 1% yolepheretsa kuwala kwa amine (kukana kukalamba kwa UV kumakulitsidwa ndi 3x)

II. Key Processing Control Points

1. Raw Material Pretreatment Standards

• Aluminium Hypophosphite: Kuyanika pa 120 ° C kwa 4h (chinyezi ≤ 0.3%)
• Zinc Borate: Kuyanika kwa mpweya pa 80 ° C kwa 2h (kupewa kuwonongeka kwa mawonekedwe a galasi)

1. Kusakaniza Njira Zenera

• Kusakaniza KwambiriKusakaniza kothamanga kwambiri (500 rpm) pa 60 ° C kwa 3min kuti muwonetsetse kulowa kwathunthu kwa plasticizer
• Kusakaniza kwachiwiriKusakaniza kothamanga kwambiri (1500 rpm) pa 90 ° C kwa 2min, kuonetsetsa kuti kutentha sikudutsa 110 ° C
• Discharge Temperature Control: ≤ 100 ° C (kupewa kuwonongeka kwa AHP)

III. Miyezo Yotsimikizira Ntchito

1. Flame Retardancy Matrix

• Kuyesa kwa LOI Gradient: 30%, 32%, 35% yofanana formulations
• UL94 Full-Series Verification: V-0 mlingo pa 1.6mm/3.2mm makulidwe
• Char Layer Quality Analysis: Kuwona kwa SEM kwa kachulukidwe kachar wosanjikiza (akulimbikitsidwa ≥80μm wosanjikiza wopitilira)

1. Ma Mechanical Performance Compensation Solutions

• Kusintha kwa Elastic Modulus: Pachiwonjezeko chilichonse cha 10% cha zoletsa moto, onjezani 1.5% DOP + 0.5% mafuta a soya a epoxidized
• Impact Mphamvu Zowonjezera: Onjezani 2% core-shell ACR impact modifier

IV. Njira Zowonjezera Mtengo

1. Mayankho a Raw Material Substitution Solutions

• Aluminium Hypophosphite: Mpaka 30% yosinthidwa ndi ammonium polyphosphate (mtengo wochepetsedwa ndi 20%, koma kukana madzi kuyenera kuganiziridwa)
• Zinc Borate: Gwiritsani ntchito 4.5% zinc borate + 1.5% barium metaborate (imathandizira kuletsa utsi)

1. Njira Zochepetsa Mtengo

• Masterbatch Technology: Zotsalira zamoto zophatikizika kale kukhala 50% zotsekereza masterbatch (amachepetsa kugwiritsa ntchito mphamvu ndi 30%)
• Kugwiritsa Ntchito Zinthu Zobwezerezedwanso: Lolani 5% regrind kuwonjezera (pamafunika 0.3% stabilizer replenishment)

V. Njira Zowongolera Zowopsa

1. Kupewa Kuwonongeka kwa Zinthu

• Real-Time Melt Viscosity Monitoring: Kuyesa kwa torque rheometer, kusinthasintha kwa torque kuyenera kukhala <5%
• Machenjezo a Mitundu: Onjezani 0.01% pH chizindikiro; kusinthika kwachilendo kumayambitsa kutseka msanga

1. Zofunikira za Chitetezo cha Zida

• Chrome-Plated Screw: Imaletsa dzimbiri la asidi (makamaka mu gawo la kufa)
• Dehumidification System: Sungani malo opangira mame ≤ -20°C
