Los hloov cov antimony trioxide / aluminium hydroxide nplaim retardant system nrog aluminium hypophosphite / zinc borate

Rau cov neeg siv khoom thov los hloov cov antimony trioxide / aluminium hydroxide nplaim hluav taws retardant nrog aluminium hypophosphite / zinc borate, cov hauv qab no yog cov txheej txheem kev ua haujlwm thiab cov ntsiab lus tseem ceeb:

I. Advanced Formulation System Design

1. Dynamic Ratio Adjustment Model

• Base RatioAluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P: B molar ratio 1.2: 1)
• High Flame Retardancy Demand: AHP 15% + ZB 5% (LOI tuaj yeem ncav cuag 35%)
• Tus nqi qis: AHP 9% + ZB 9% (Leveraging ZB tus nqi kom zoo dua, txo tus nqi los ntawm 15%)

1. Synergist Combination Solutions

• Hom Kev Txhaum Cai: Ntxiv 2% zinc molybdate + 1% nano-kaolin (kev haus luam yeeb txo los ntawm 40%)
• Hom kev txhawb zog: Ntxiv 3% deg-hloov boehmite (flexural zog nce 20%)
• Huab cua-Resistant Hom: Ntxiv 1% hindered amine teeb stabilizer (UV aging kuj txuas ntxiv los ntawm 3x)

II. Cov Ntsiab Cai Tswj Xyuas Cov Ntsiab Lus

1. Raw Material Pretreatment Standards

• Aluminium Hypophosphite: Nqus kom qhuav ntawm 120 ° C rau 4h (moisture ≤ 0.3%)
• Zinc Borate: Airflow ziab ntawm 80 ° C rau 2h (kom tiv thaiv cov qauv siv lead ua puas tsuaj)

1. Mixing Process Qhov rai

• Kev sib xyaw ua ke: Tsawg-ceev sib tov (500 rpm) ntawm 60 ° C rau 3min los xyuas kom meej tag nrho cov plasticizer nkag
• Secondary MixingKev sib xyaw ua haujlwm siab (1500 rpm) ntawm 90 ° C rau 2min, kom ntseeg tau tias kub tsis tshaj 110 ° C
• Kev tswj qhov kub thiab txias: ≤ 100 ° C (kom tiv thaiv kom tsis txhob ntxov ntxov AHP decomposition)

III. Daim Ntawv Pov Thawj Ua Haujlwm

1. Nplaim Retardancy Matrix

• LOI Gradient Testing: 30%, 32%, 35% cov formulations
• UL94 Daim Ntawv Pov Thawj Ua Haujlwm Tag NrhoV-0 ntsuam xyuas ntawm 1.6mm / 3.2mm thickness
• Char Layer Quality Analysis: SEM soj ntsuam ntawm char txheej ceev (pom zoo ≥80μm txheej nruam)

1. Mechanical Performance Compensation Solutions

• Elastic Modulus Kho: Rau txhua 10% nce hauv nplaim hluav taws, ntxiv 1.5% DOP + 0.5% epoxidized soybean roj
• Impact Strength Enhancement: Ntxiv 2% core-plhaub ACR cuam tshuam hloov pauv

IV. Tus nqi optimization tswv yim

1. Raw Material Substitution Solutions

• Aluminium Hypophosphite: Txog li 30% hloov tau nrog ammonium polyphosphate (tus nqi txo los ntawm 20%, tab sis dej kuj yuav tsum tau txiav txim siab)
• Zinc Borate: Siv 4.5% zinc borate + 1.5% barium metaborate (txhim kho cov pa luam yeeb)

1. Txheej txheem nqi-txo kev ntsuas

• Masterbatch Technology: Pre-compound nplaim taws retardants rau hauv 50% concentration masterbatch (txo qis kev siv hluav taws xob los ntawm 30%)
• Kev siv cov khoom siv rov ua dua tshiab: Tso cai 5% regrind ntxiv (yuav tsum tau 0.3% stabilizer ntxiv)

V. Kev Tswj Xyuas Kev Nyab Xeeb

1. Kev tiv thaiv kev degradation

• Real-Time Melt Viscosity Monitoring: Kev ntsuas torque rheometer, torque fluctuation yuav tsum <5%
• Xim ceeb toom Mechanism: Ntxiv 0.01% pH qhia; txawv txav discoloration ua rau kev kaw tam sim

1. Cov Khoom Siv Tiv Thaiv Cov Cai

• Chrome Plated Ntsia Hlau: Tiv thaiv acid corrosion (tshwj xeeb tshaj yog nyob rau hauv seem tuag)
• Dehumidification System: Khaws qhov chaw ua haujlwm dew point ≤ -20 ° C
