Qaaciddada tixraaca ololka aan halogen lahayn ee loogu talagalay dhejisyada elektaroonigga ah ee acrylic-ka ku salaysan biyaha

Nidaamyada acrylic-ka ku salaysan biyaha, xaddiga lagu daray ee aluminium hypophosphite (AHP) iyo zinc borate (ZB) waa in lagu go'aamiyaa iyadoo lagu saleynayo shuruudaha gaarka ah ee codsiga (sida qiimeynta dib-u-dhaca ololka, dhumucda dahaarka, shuruudaha waxqabadka jireed, iwm.) iyo saameyntooda isku-dhafka ah. Hoos waxaa ku qoran talooyin guud iyo kala duwanaanshaha tixraaca:

I. Tixraaca Lacagta Ku-darka Aasaasiga ah

Shaxda: Ku darista iyo Sharaxaadaha lagu taliyay ee ka hortagga ololka

II. Hagaajinta Saamiyada Isku-dhafan

1. Saamiyada Isku-dhafka Caadiga ah:

• AHP:ZB = 2:1 ~ 4:1(tusaale ahaan, 15% AHP + 5% ZB, wadarta guud 20%).
• Si tijaabo ah u hagaaji saamiga, tusaale ahaan:
• Baahida sare ee dib u dhaca ololka:AHP 15% ~ 20%, ZB 5% ~ 8%.
• Sifooyinka jireed ee dheellitiran:AHP 10% ~ 15%, ZB 3% ~ 5%.

1. Saamaynta Wadajirka ah:

• Zinc borate wuxuu kordhiyaa dib u dhigista ololka isagoo:
• Xasilinta sameynta dabeecadda (la falgalka aluminium fosfate oo ay soo saarto AHP).
• Biyo xidhxidhan ayaa sii daaya si ay u nuugaan kulaylka una khafiifiyaan gaasaska ololaya.

III. Tallaabooyinka Xaqiijinta Tijaabada

1. Tijaabada Tallaabo-tallaabo ah:

• Tijaabin shaqsiyeed:Marka hore si gaar ah u qiimee AHP (5% ~ 20%) ama ZB (5% ~ 15%) si aad u ogaato dib-u-celinta ololka (UL-94, LOI) iyo waxqabadka dahaarka (ku dhejinta, adkaanta, iska caabbinta biyaha).
• Hagaajinta isku-dhafka ah:Ka dib markaad doorato qaddarka AHP ee aasaasiga ah, si tartiib tartiib ah ugu dar ZB (tusaale ahaan, 3% ilaa 8% marka AHP ay tahay 15%) oo arag horumar ku yimaada dib u dhaca dabka iyo waxyeellooyinka.

1. Tilmaamayaasha Waxqabadka Muhiimka ah:

• Daahfurka ololka:LOI (bartilmaameedka ≥28%), qiimeynta UL-94 (V-0/V-1), cufnaanta qiiqa.
• Sifooyinka jireed:Samaynta filimka, dhegdheg (ASTM D3359), iska caabbinta biyaha (ma jiraan wax dildilaac ah ka dib 48 saacadood oo quusitaan ah).

IV. Tixgelinnada Muhiimka ah

• Xasiloonida Kala-fidinta:
• AHP waa hygroscopic—ka hor qalaji ama isticmaal noocyo dusha sare wax laga beddelay.
• Isticmaal kala-firdhiyeyaal (tusaale ahaan, BYK-190, TEGO Dispers 750W) si aad u hagaajiso isku-midnimada iyo ka hortagga kala-firdhinta.
• Iswaafajinta pH:
• Nidaamyada akrilik-ka ee biyaha ku salaysan waxay caadi ahaan leeyihiin pH ah 8–9; hubi in AHP iyo ZB ay xasilloon yihiin (iska ilaali in la daadiyo ama la kala daato).
• U hoggaansanaanta Sharciyeynta:
• AHP waa inay buuxisaa shuruudaha RoHS ee aan lahayn halogen; ZB waa inay isticmaashaa darajooyin wasakhaysan oo bir culus oo hooseeya.

V. Xalalka Kale ama Kaabista ah

• Melamine Polyphosphate (MPP):Waxay sii xoojin kartaa dib u dhigista ololka marka lagu daro AHP (tusaale ahaan, 10% AHP + 5% MPP + 3% ZB).
• Waxyaabaha ka hortagaya ololka Nano:Nano-grade ZB (ku darista ayaa hoos loogu dhigay 1% ~ 3%) ama laba-hydroxides oo lakabaysan (LDH) si loo hagaajiyo saameynta caqabadaha.

VI. Talooyin Kooban

• Qaaciddada bilowga ah:AHP 10% ~ 15% + ZB 3% ~ 5% (wadarta 13% ~ 20%), ka dibna hagaaji.
• Habka Xaqiijinta:Tijaabi muunado yaryar oo loogu talagalay LOI iyo UL-94 inta aad qiimeynayso sifooyinka farsamada.
