Kutsiva antimony trioxide/aluminium hydroxide flame retardant system nealuminium hypophosphite/zinc borate.

Pachikumbiro chemutengi chekutsiva antimony trioxide/aluminium hydroxide flame retardant system nealuminium hypophosphite/zinc borate, zvinotevera hurongwa hwekuita zvehunyanzvi hwekuita uye mapoinzi akakosha ekutonga:

I. Advanced Formulation System Dhizaini

1. Dynamic Ratio Adjustment Model

• Base Ratio: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• High Flame Retardancy Demand: AHP 15% + ZB 5% (LOI inogona kusvika 35%)
• Yakaderera-Mutengo Solution: AHP 9% + ZB 9% (Kushandisa ZB's cost advantage, kunoderedza mutengo ne15%)

1. Synergist Combination Solutions

• Kusvuta Type: Wedzera 2% zinc molybdate + 1% nano-kaolin (hutsi hwehutsi hwakaderedzwa ne40%)
• Rudzi rwekusimbisa: Wedzera 3% pamusoro-yakagadziridzwa boehmite (flexural simba yakawedzera ne20%)
• Chimiro Chisingamirire Mamiriro ekunze: Wedzera 1% yakavharira amine light stabilizer (UV kuchembera kuramba kwakawedzerwa ne3x)

II. Key Processing Control Points

1. Raw Material Pretreatment Standards

• Aluminium Hypophosphite: Vacuum drying pa120°C kwe4h (unyoro ≤ 0.3%)
• Zinc Borate: Kuomeswa kwemhepo pa80 ° C kwe2h (kudzivirira kukuvara kwekristaro)

1. Kusanganisa Maitiro Window

• Primary Mixing: Yakaderera-kumhanya kusanganisa (500 rpm) pa60 ° C ye3min kuti ive nechokwadi chekupinda kweplasticizer yakazara.
• Secondary Mixing: High-speed kusanganisa (1500 rpm) pa 90 ° C ye 2min, kuve nechokwadi kuti tembiricha haipfuure 110 ° C.
• Discharge Temperature Control: ≤ 100 ° C (kudzivirira nguva isati yakwana AHP kuora)

III. Performance Verification Standards

1. Flame Retardancy Matrix

• LOI Gradient Testing: 30%, 32%, 35% inoenderana formulations
• UL94 Yakazara-Series Verification: V-0 mwero pa 1.6mm/3.2mm ukobvu
• Char Layer Quality Analysis: SEM kucherechedzwa kwechar layer density (inokurudzirwa ≥80μm inoenderera layer)

1. Mechanical Performance Compensation Solutions

• Elastic Modulus Kugadziriswa: Kune yega yega yegumi muzana yekuwedzera mumurazvo wemoto, wedzera 1.5% DOP + 0.5% epoxidized soya bean mafuta
• Impact Simba Kuwedzera: Wedzera 2% core-shell ACR maitiro ekugadzirisa

IV. Mutengo Wekugadzirisa Matanho

1. Raw Material Kutsiva Solutions

• Aluminium Hypophosphite: Kusvikira ku30% inogona kutsiviwa neammonium polyphosphate (mutengo wakaderedzwa ne20%, asi kuramba mvura kunofanirwa kutariswa)
• Zinc Borate: Shandisa 4.5% zinc borate + 1.5% barium metaborate (inovandudza kudzvinyirira utsi)

1. Maitiro-Kuderedza Mari Matanho

• Vadivelu Comedy Masterbatch Technology: Pre-compound flame retardants kuita 50% concentration masterbatch (inoderedza kushandiswa kwesimba ne30%)
• Recycled Material Utilization: Bvumira 5% regrind yekuwedzera (inoda 0.3% stabilizer replenishment)

V. Matanho Ekudzora Njodzi

1. Kudzivirira Kusvibiswa Kwezvinhu

• Real-Nguva Melt Viscosity Monitoring: Torque rheometer yekuyedza, torque fluctuation inofanirwa kunge iri <5%
• Ruvara Yambiro Mechanism: Wedzera 0.01% pH chiratidzo; abnormal discoloration inokonzeresa kudzima nekukurumidza

1. Equipment Dziviriro Zvinodiwa

• Chrome-Plated Screw: Inodzivirira acid corrosion (kunyanya muchikamu chefa)
• Dehumidification System: Chengetedza kugadzirisa nharaunda dova point ≤ -20°C
