Iji dochie sistemu antimony trioxide/aluminum hydroxide flame retardant na aluminum hypophosphite/zinc borate

Maka arịrịọ onye ahịa iji aluminum hypophosphite/zinc borate dochie sistemu antimony trioxide/aluminum hydroxide flame retardant, ihe ndị a bụ atụmatụ nhazi teknụzụ na isi ihe njikwa:

I. Nhazi Sistemụ Nhazi Dị Elu

1. Ụdị Mgbanwe Oke Mgbanwe

• Oke Ntọala: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Ọchịchọ Nkwụsị Ọkụ Dị Elu: AHP 15% + ZB 5% (LOI nwere ike iru 35%)
• Ngwọta Dị Ọnụ Ala: AHP 9% + ZB 9% (Iji uru ọnụ ahịa ZB mee ihe, belata ọnụ ahịa site na 15%)

1. Ngwọta Njikọta Synergist

• Ụdị Mgbochi Anwụrụ: Tinye 2% zinc molybdate + 1% nano-kaolin (njupụta anwụrụ ọkụ belatara site na 40%)
• Ụdị Mmesi Ike: Tinye 3% boehmite agbanwere n'elu (ike flexural mụbara site na 20%)
• Ụdị Na-eguzogide Ihu Igwe: Tinye 1% ihe na-eme ka amine na-eguzosi ike n'ihe (ọ na-agbatị ike ịka nká site na UV ugboro atọ)

II. Isi Ihe Njikwa Nhazi Isi

1. Ụkpụrụ Tupu Ọgwụgwọ Ihe Ndị Dị Mfe

• Aluminom Hypophosphite: Ịkpọ nkụ n'ime ihe mkpofu na okpomọkụ 120°C ruo awa 4 (mmiri ≤ 0.3%)
• Zinc Borate: Ikuku na-akpọ nkụ na 80°C ruo awa 2 (iji gbochie mmebi nke nhazi kristal)

1. Window Usoro Ngwakọta

• Ngwakọta IsiNgwakọta dị obere ọsọ (500 rpm) na 60°C maka nkeji 3 iji hụ na plasticizer zuru oke abanyela
• Ngwakọta nke AbụọNgwakọta dị elu (1500 rpm) na 90°C maka nkeji 2, na-eme ka okpomọkụ ghara ịgafe 110°C
• Njikwa Okpomọkụ Mwepụ: ≤ 100°C (iji gbochie ire ere AHP tupu oge eruo)

III. Ụkpụrụ Nnwale Arụmọrụ

1. Matriks Retardancy nke ire ọkụ

• Nnwale Gradient LOI: 30%, 32%, 35% usoro kwekọrọ
• Nkwenye Usoro zuru oke nke UL94: Ọkwa V-0 na ọkpụrụkpụ 1.6mm/3.2mm
• Nyocha Ogo nke Char Layer: Nleba anya SEM nke njupụta oyi akwa char (a na-atụ aro ka oyi akwa na-aga n'ihu ≥80μm)

1. Ngwọta Ụgwọ Ọrụ Mekaniki

• Mgbanwe Modulu Elastic: Maka mmụba 10% ọ bụla na ihe na-egbochi ọkụ, tinye 1.5% DOP + 0.5% mmanụ soybean epoxidized
• Mmelite Ike Mmetụta: Tinye 2% ihe na-agbanwe mmetụta ACR isi-shei

IV. Atụmatụ Nhazi Ọnụ Ego

1. Ngwọta Mgbanwe Ihe Ndị Dị n'Aka

• Aluminom Hypophosphite: Ruo 30% enwere ike iji ammonium polyphosphate dochie ya (ọnụ ahịa ya belatara site na 20%, mana a ga-atụle iguzogide mmiri)
• Zinc Borate: Jiri 4.5% zinc borate + 1.5% barium metaborate (na-eme ka mbelata anwụrụ ọkụ ka mma)

1. Usoro Mbelata Ọnụego Usoro

• Teknụzụ Masterbatch: Ndị na-egbochi ire ọkụ tupu ha abanye na masterbatch nke 50% (na-ebelata oriri ike nhazi site na 30%)
• Ojiji Ihe Emegharịrị: Kwe ka mgbakwunye 5% gbanwee (chọrọ 0.3% nhazi ihe na-eme ka ihe kwụsie ike)

V. Usoro Njikwa Ihe Ize Ndụ

1. Mgbochi Mmebi Ihe

• Nlekota Viscosity nke Oge Gbazee: Nnwale rheometer torque, mgbanwe torque kwesịrị ịbụ <5%
• Usoro Ịdọ Aka ná Ntị Agba: Tinye ihe ngosi pH 0.01%; mgbanwe agba na-adịghị mma na-akpali mmechi ozugbo

1. Ihe achọrọ maka Nchedo Ngwaọrụ

• Skrọ e ji kpụọ chrome: Na-egbochi mmebi acid (karịsịa na ngalaba anwụ)
• Sistemụ Mwepụ Mmiri: Nọgide na-enwe ebe a na-eme nhazi gburugburu ebe obibi nke ọma ruo -20°C
