Kutsiva sisitimu yeantimony trioxide/aluminum hydroxide flame retardant nealuminium hypophosphite/zinc borate

Kana mutengi achikumbira kuti atsive antimony trioxide/aluminum hydroxide flame retardant system nealuminium hypophosphite/zinc borate, zvinotevera ndizvo hurongwa hwekushandisa hune hurongwa uye zvinhu zvakakosha zvekudzora:

I. Kugadzira Sisitimu Yepamusoro Yekugadzira

1. Muenzaniso weDynamic Ratio Adjustment

• Huwandu hwehwaro: Aluminum hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Kudiwa Kwekukurumidza Kudzima Murazvo: AHP 15% + ZB 5% (LOI inogona kusvika 35%)
• Mhinduro Inodhura Zvishoma: AHP 9% + ZB 9% (Kushandisa mukana weZB wekushandisa mari, kunoderedza mutengo ne15%)

1. Mhinduro dzeMusanganiswa weSynergist

• Rudzi rwekudzvinyirira utsi: Wedzera 2% zinc molybdate + 1% nano-kaolin (huwandu hweutsi hwakaderedzwa ne40%)
• Rudzi rwekusimbisa: Wedzera 3% boehmite yakagadziriswa pamusoro (simba reflexural rakawedzerwa ne20%)
• Rudzi Runodzivirira Mamiriro Ekunze: Wedzera 1% inodzivisa amine light stabilizer (kuramba kukwegura kweUV kunowedzerwa ne3x)

II. Mapoinzi Ekugadzirisa Makoshero

1. Maitiro Ekurapa Zvinhu Zvisina Kugadzirwa

• Aruminiyamu Hypophosphite: Kuomesa ne vacuum cleaner pa 120°C kwemaawa mana (hunyoro ≤ 0.3%)
• Zinc Borate: Kuomesa mhepo pa80°C kwemaawa maviri (kudzivirira kukuvara kwechimiro chekristaro)

1. Hwindo reKusanganisa Maitiro

• Kusanganisa Kwekutanga: Kusanganisa nekukurumidza (500 rpm) pa60°C kwemaminitsi matatu kuti ive nechokwadi chekuti plasticizer inopinda zvakakwana
• Kusanganisa kwechipiri: Kusanganisa nekukurumidza (1500 rpm) pa90°C kwemaminitsi maviri, zvichiita kuti tembiricha isapfuure 110°C
• Kudzora Kupisa Kwekubuda Mumhepo: ≤ 100°C (kudzivirira kuora kweAHP nguva isati yakwana)

III. Maitiro Ekusimbisa Kushanda

1. Matrix yeKudzora Murazvo

• Kuedzwa kweGradient yeLOI: 30%, 32%, 35% mafomura anoenderana
• Kusimbiswa kweUL94 Full-Series: V-0 chiyero paukobvu hwe1.6mm/3.2mm
• Kuongorora Hunhu hweChar Layer: Kuongororwa kweSEM kwehuwandu hwechar layer (inokurudzirwa ≥80μm continuous layer)

1. Mhinduro dzeKubhadharisa Mashandiro Emakanika

• Kugadziriswa kweElastic Modulus: Pakuwedzera kwe10% kwechinhu chinodzivirira moto, wedzera 1.5% DOP + 0.5% mafuta esoya akasanganiswa ne epoxidized.
• Kuvandudza Simba reMhedzisiro: Wedzera 2% core-shell ACR impact modifier

IV. Maitiro Ekugadzirisa Mutengo

1. Mhinduro dzeKutsiva Zvinhu Zvisina Kugadzirwa

• Aruminiyamu Hypophosphite: Kusvika 30% inogona kutsiviwa neammonium polyphosphate (mutengo wakaderera ne20%, asi kuramba mvura kunofanira kufungwa nezvako)
• Zinc Borate: Shandisa 4.5% zinc borate + 1.5% barium metaborate (inovandudza kudzvinyirirwa kweutsi)

1. Matanho Ekuderedza Mutengo

• Tekinoroji yeMasterbatch: Pre-compound fire retardants kuita 50% concentration masterbatch (inoderedza kushandiswa kwesimba rekugadzirisa ne30%)
• Kushandiswa Kwezvinhu Zvakadzokororwa: Bvumira kuwedzera 5% yekukuya (inoda 0.3% stabilizer replenished)

V. Matanho Ekudzivirira Njodzi

1. Kudzivirira Kuora Kwezvinhu

• Kuongororwa kweViscosity yeMelt-Time Real-Time: Kuongororwa kwe torque rheometer, kushanduka kwe torque kunofanira kuva <5%
• Nzira Yekunyevera Ruvara: Wedzera chiratidzo chepH che0.01%; kushata kweruvara kusingawanzoitiki kunokonzera kudzima kwemavara ipapo ipapo

1. Zvinodiwa zveDziviriro yeMidziyo

• Screw Yakafukidzwa neChrome: Inodzivirira ngura yeasidhi (kunyanya muchikamu chekufa)
• Sisitimu yekubvisa hunyoro: Chengetedza nzvimbo yekugadzirisa ine dova ≤ -20°C
