Si loogu beddelo nidaamka dab-damiska antimony trioxide/aluminium hydroxide aluminium hypophosphite/zinc borate

Codsiga macaamiisha ee ah in nidaamka antimony trioxide/aluminium hydroxide ee ololka ka hortagga uumi-baxa lagu beddelo aluminium hypophosphite/zinc borate, kuwa soo socda waa qorshe fulin farsamo oo nidaamsan iyo qodobbada xakamaynta ee muhiimka ah:

I. Naqshadeynta Nidaamka Qaabaynta Sare

1. Qaabka Hagaajinta Saamiga Firfircoon

• Saamiga Saldhigga: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (Saamaynta molar-ka P:B 1.2:1)
• Baahida Dib-u-Celinta Ololka Sare: AHP 15% + ZB 5% (LOI wuxuu gaari karaa 35%)
• Xalka Qiimo Jaban: AHP 9% + ZB 9% (Ka faa'iidaysiga faa'iidada kharashka ZB, waxay hoos u dhigaysaa kharashka 15%)

1. Xalalka Isku-dhafka ah ee Isku-dhafka ah

• Nooca Xakamaynta Qiiqa: Ku dar 2% zinc molybdate + 1% nano-kaolin (cufnaanta qiiqa ayaa hoos u dhacday 40%)
• Nooca Xoojinta: Ku dar 3% boehmite-ka dusha sare wax laga beddelay (xoogga dabacsanaanta ayaa kordhay 20%)
• Nooca Cimilada u adkaysta: Ku dar 1% xasiliyaha iftiinka amine ee caqabad ku ah (iska caabbinta gabowga UV ayaa sii kordheysa 3 jeer)

II. Qodobbada Xakamaynta Habaynta Muhiimka ah

1. Heerarka Ka Hortagga Daawaynta Alaabta Ceeriin

• Aluminium Hypophosphite: Ku qalaji faakuumka heerkul ah 120°C muddo 4 saacadood ah (qoyaan ≤ 0.3%)
• Zinc BorateQallajinta qulqulka hawada 80°C muddo 2 saacadood ah (si looga hortago waxyeelada qaab-dhismeedka kiristaalka)

1. Daaqadda Habka Isku-darka

• Isku-darka Aasaasiga ahIsku-darka xawaare hoose (500 rpm) heerkul ah 60°C muddo 3 daqiiqo ah si loo hubiyo in si buuxda loo geliyo balaastikada
• Isku-darka LabaadIsku-darka xawaaraha sare leh (1500 rpm) 90°C muddo 2 daqiiqo ah, taasoo hubinaysa in heerkulku aanu dhaafin 110°C
• Xakamaynta Heerkulka Soo Daadinta: ≤ 100°C (si looga hortago burburka AHP ee dhicis ah)

III. Heerarka Xaqiijinta Waxqabadka

1. Matrix-ka Dib-u-Celinta Ololka

• Imtixaanka Jaangooyooyinka LOI: 30%, 32%, 35% qaacidooyinka u dhigma
• Xaqiijinta Taxanaha Buuxa ee UL94: Qiimaynta V-0 oo ah dhumucda 1.6mm/3.2mm
• Falanqaynta Tayada Lakabka Char: Daawashada SEM ee cufnaanta lakabka char (lakabka joogtada ah ee lagu taliyay ≥80μm)

1. Xalalka Magdhawga Waxqabadka Farsamada

• Hagaajinta Modulus-ka Laablaaban: 10% kasta oo kor u kaca daawada dabka ka hortagta, ku dar 1.5% DOP + 0.5% saliid soybean ah oo epoxidized ah
• Horumarinta Xoogga Saamaynta: Ku dar 2% wax ka beddelka saameynta ACR ee qolofta-core-ka ah

IV. Istaraatiijiyadaha Hagaajinta Kharashka

1. Xalalka Beddelka Walxaha Cayriin

• Aluminium Hypophosphite: Ilaa 30% waxaa lagu beddeli karaa ammonium polyphosphate (qiimaha ayaa hoos u dhacay 20%, laakiin waa in la tixgeliyaa iska caabbinta biyaha)
• Zinc Borate: Isticmaal 4.5% zinc borate + 1.5% barium metaborate (waxay hagaajisaa xakamaynta qiiqa)

1. Tallaabooyinka Yaraynta Kharashka Geedi socodka

• Tiknoolajiyadda Master-ka: Kahor inta aan la isticmaalin, walxaha dabka celiya waxay u beddelaan heerka ugu sarreeya ee 50% (waxay yareeyaan isticmaalka tamarta 30%)
• Isticmaalka Walxaha Dib Loo Isticmaalo: U ogolow 5% dib u shiidid (waxay u baahan tahay dib u buuxinta xasiliyaha 0.3%)

V. Tallaabooyinka Xakamaynta Khatarta

1. Ka Hortagga Burburka Maaddada

• Kormeerka Dheecaanka Dhalaalka Waqtiga-dhabta ah: Tijaabada wareegga wareegga, isbeddelka wareegga waa inuu ahaadaa <5%
• Habka Digniinta Midabka: Ku dar tilmaame pH ah 0.01%; midab-beddel aan caadi ahayn ayaa kiciya xidhitaan degdeg ah

1. Shuruudaha Ilaalinta Qalabka

• Boorsooyin lagu dahaadhay Chrome: Waxay ka hortagtaa daxalka aashitada (gaar ahaan qaybta dhimaha)
• Nidaamka Qashinka Qashinka: Ku hay heerka dharabka deegaanka habaynta ≤ -20°C
