Ho nka sebaka sa antimony trioxide/aluminium hydroxide retardant system ka aluminium hypophosphite/zinc borate.

Bakeng sa kopo ea moreki ea ho nka sebaka sa antimony trioxide/aluminium hydroxide flame retardant system ka aluminium hypophosphite/zinc borate, se latelang ke moralo o hlophisitsoeng oa ts'ebetso ea tekheniki le lintlha tsa bohlokoa tsa taolo:

I. Moralo oa Sistimi ea Tlhahiso e tsoetseng pele

1. Moetso oa Phetoho ea Karolelano e Matla

• Karolelano ea motheo: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Tlhokahalo e phahameng ea ho lieha ha malakabe: AHP 15% + ZB 5% (LOI e ka fihla ho 35%)
• Tharollo e Theko e tlaase: AHP 9% + ZB 9% (Ho sebelisa monyetla oa litšenyehelo tsa ZB, ho fokotsa litšenyehelo ka 15%)

1. Synergist Combination Solutions

• Mofuta oa Khatello ea Mosi: Kenya 2% zinc molybdate + 1% nano-kaolin (boima ba mosi bo fokotsehile ka 40%)
• Mofuta oa Matlafatso: Eketsa 3% boehmite e fetotsoeng holim'a metsi (matla a feto-fetohang a eketsehile ka 20%)
• Mofuta o Hanyetsang Boemo ba Leholimo: Eketsa 1% e sitisang amine light stabilizer (UV ea botsofali e atolosoa ke 3x)

II. Lintlha tsa Taolo ea Ts'ebetso ea Bohlokoa

1. Raw Material Pretreatment Standards

• Hypophosphite ea aluminium: Ho omisa ka vacuum ho 120 ° C bakeng sa 4h (mongobo ≤ 0.3%)
• Borate ea Zinc: Ho omisa moea ka 80 ° C bakeng sa 2h (ho thibela tšenyo ea sebopeho sa kristale)

1. Ho Kopanya Tshebetso Fensetere

• Motsoako oa Pele: Ho kopanya ka lebelo le tlase (500 rpm) ho 60 ° C bakeng sa 3min ho netefatsa ho kenella ka botlalo ha polasetiki
• Motsoako oa bobeli: Ho kopanya ka lebelo le phahameng (1500 rpm) ho 90 ° C bakeng sa 2min, ho netefatsa hore mocheso ha o fete 110 ° C
• Taolo ea Mocheso oa ho Laola: ≤ 100°C (ho thibela ho senyeha ha AHP pele ho nako)

III. Maemo a Tiiso ea Ts'ebetso

1. Flame Retardancy Matrix

• Liteko tsa LOI Gradient: 30%, 32%, 35% e lumellanang le metsoako
• Netefatso e felletseng ea UL94: tekanyo ea V-0 ho 1.6mm / 3.2mm botenya
• Tlhahlobo ea boleng ba Char Layer: Tlhokomelo ea SEM ea sekhahla sa char layer (e khothaletsoa ≥80μm e tsoelang pele)

1. Litharollo tsa Matšeliso a Ts'ebetso ea Mechini

• Phetoho ea Elastic Modulus: Bakeng sa keketseho e 'ngoe le e' ngoe ea 10% ea se thibelang malakabe, eketsa 1.5% DOP + 0.5% oli ea soya e epoxidized
• Ntlafatso ea Matla a Tšusumetso: Kenya 2% core-shell ACR impact modifier

IV. Mekhoa ea ho ntlafatsa litšenyehelo

1. Litharollo tsa ho fetola lintho tse tala

• Hypophosphite ea aluminium: Ho fihla ho 30% e ka nkeloang sebaka ka ammonium polyphosphate (litšenyehelo li fokotsoe ka 20%, empa ho hanyetsa metsi ho tlameha ho nahanoa)
• Borate ea Zinc: Sebelisa 4.5% zinki borate + 1.5% barium metaborate (e ntlafatsa khatello ea mosi)

1. Mehato ea Phokotso ea Litšenyehelo

• Theknoloji ea Masterbatch: Li-pre-compound flame retardants ho 50% concentration masterbatch (e fokotsa tšebeliso ea matla ka 30%).
• Tšebeliso e Tsosolositsoeng ea Lintho: Lumella 5% regrind tlatsetso (e hloka 0.3% stabilizer replenishment)

V. Mehato ea Taolo ea Kotsi

1. Thibelo ea ho Senyeha ha Lintho

• Tlhokomelo ea Viscosity ea Nako ea 'Nete ea Nako ea 'Nete: Teko ea rheometer ea torque, phetoho ea torque e lokela ho ba <5%
• Mokhoa oa Temoso ea Mebala: Eketsa 0.01% pH indicator; mmala o sa tlwaelehang o baka ho tima hanghang

1. Litlhoko tsa Tšireletso ea Thepa

• Chrome-Plated Screw: E thibela kutu ea acid (haholo-holo karolong ea die)
• Sistimi ea ho tlosa mongobo: Boloka sebaka sa ho sebetsa sebakeng sa phoka ≤ -20°C
