Samaynta tixraaca dib-u-dejinta olol-la'aanta Halogen ee xabagta elektiroonigga ah ee akril ee biyaha ku salaysan

Nidaamyada akril ee biyaha ku salaysan, qadarka dheeriga ah ee aluminium hypophosphite (AHP) iyo zinc borate (ZB) waa in lagu go'aamiyaa iyada oo ku saleysan shuruudaha codsiga gaarka ah (sida qiimeynta dib u dhigista ololka, dhumucda dahaarka, shuruudaha waxqabadka jirka, iwm.) iyo saameyntooda isdhexgalka. Hoos waxaa ah talooyinka guud iyo tixraacyada kala duwan:

I. Tixraaca Qadarka Ku darida Saldhigga

Shaxda: Kordhinta iyo Sharaxaadaha Ololka Lagu Talinayo

II. Hagaajinta Saamiyada Isku-dhafka ah

1. Saamiyada isku dhafan ee caadiga ah:

• AHP:ZB = 2:1 ~ 4:1(tusaale, 15% AHP + 5% ZB, wadarta 20%).
• Isku hagaaji saamiga si tijaabo ah, tusaale ahaan:
• Baahida dib u dhigista ololka sare:AHP 15% ~ 20%, ZB 5% ~ 8%.
• Sifooyin jidheed oo dheellitiran:AHP 10% ~ 15%, ZB 3% ~ 5%.

1. Saamaynta Isku-dhafka:

• Zinc borate waxay wanaajisaa dib u dhaca ololka:
• Samaynta jaangooyooyinka xasilinta (la falgalka fosfat aluminium ee ay dhaliso AHP).
• Sii daynta biyaha xidhxidhan si ay u nuugaan kulaylka oo ay u milmaan gaasas ololaya.

III. Talaabooyinka Xaqiijinta Tijaabada

1. Tijaabada Tallaabo ah:

• Imtixaan shaqsiyeed:Marka hore u qiimee AHP (5% ~ 20%) ama ZB (5% ~ 15%) si gooni gooni ah dib u dhigista ololka (UL-94, LOI) iyo waxqabadka daahan (adhesion, engegnaanta, caabbinta biyaha).
• Hagaajinta isku dhafka:Ka dib markaad doorato qadarka aasaasiga ah ee AHP, si kordhin ku dar ZB (tusaale, 3% ilaa 8% marka AHP ay tahay 15%) oo u fiirso hagaajinta dib u dhaca ololka iyo waxyeelada.

1. Tilmaamayaasha Waxqabadka Muhiimka ah:

• Dib u dhigista ololka:LOI ( bartilmaameed ≥28%), UL-94 rating (V-0/V-1), cufnaanta qiiqa.
• Tilmaamaha jirka:Sameynta filimka, adhesion (ASTM D3359), iska caabbinta biyaha (aan lahayn delamination ka dib 48h immersion).

IV. Tixgelinta Muhiimka ah

• Xasiloonida Kala-firdhinta:
• AHP waa hygroscopic-ka hor engegan ama isticmaal noocyo dusha wax laga beddelay.
• Isticmaal walxaha kala firdhiya (tusaale, BYK-190, TEGO Dispers 750W) si aad u wanaajiso isku midnimada ugana hortagto kala-saarid
• Waafaqsanaanta pH:
• Nidaamyada akril ee biyaha ku salaysan waxay caadi ahaan leeyihiin pH 8-9; Hubi in AHP iyo ZB ay xasiloon yihiin (iska ilaali hydrolysis ama burburka).
• U Hogaansanaanta Xeerarka
• AHP waa inay buuxisaa shuruudaha RoHS ee aan halogen ahayn; ZB waa inay isticmaashaa darajooyinka wasakhda birta culus ee hoose.

V. Xalka Beddelka ah ama Kaabista

• Melamine Polyphosphate (MPP):Waxay sii kordhin kartaa dib u dhaca ololka marka lagu daro AHP (tusaale, 10% AHP + 5% MPP + 3% ZB).
• Nano Flame Retardants:Nano-grade ZB (ku-darka ayaa hoos loo dhigay 1% ~ 3%) ama laba-jibbaaran hydroxides (LDH) si loo hagaajiyo saamaynta xannibaadda.

VI. Soo-jeedin kooban

• Bilowga qaabaynta:AHP 10% ~ 15% + ZB 3% ~ 5% (wadarta 13% ~ 20%), ka dibna hagaajin
• Habka ansixinta:Tijaabi muunado yar-yar oo LOI iyo UL-94 ah iyadoo la qiimeynayo sifooyinka farsamada.
