Yuav ua li cas kom txo tau qhov ceev ntawm cov pa luam yeeb rau cov nplaum epoxy nrog cov nplaim taws retardant AHP thiab MCA?

Qhov ntxiv cov txhuas hypophosphite thiab MCA rau hauv cov nplaum epoxy ua rau muaj pa luam yeeb ntau. Kev siv zinc borate los txo cov pa luam yeeb thiab cov pa luam yeeb ua rau muaj pa luam yeeb ntau yog qhov ua tau, tab sis cov mis uas twb muaj lawm yuav tsum tau ua kom zoo rau qhov sib piv.

1. Kev Tswj Pa Luam Yeeb ntawm Zinc Borate

Zinc borate yog ib qho tshuaj uas ua rau cov pa luam yeeb tsis ua haujlwm zoo thiab ua rau cov nplaim taws tsis kub hnyiab. Nws cov txheej txheem suav nrog:

• Kev Txhawb Nqa Kev Tsim Char: Tsim ib txheej char ntom ntom thaum lub sijhawm hlawv, cais cov pa oxygen thiab cua sov, thiab txo cov pa roj uas yooj yim hlawv tawm.
• Kev Txwv Tsis Pub Haus Luam YeebCov tshuaj ua rau cov tshuaj sib txuas ua ke kom txo tau cov pa luam yeeb, txo cov pa luam yeeb kom tsawg (tshwj xeeb tshaj yog rau cov polymers xws li epoxy).
• Cov nyhuv synergisticThaum muab cov tshuaj tua hluav taws uas muaj phosphorus (piv txwv li, aluminium hypophosphite) thiab nitrogen (piv txwv li, MCA) ua rau hluav taws kub zoo dua.

2. Lwm yam tshuaj lossis tshuaj ntxiv rau kev tswj pa luam yeeb

Yog xav kom zoo dua ntawm kev tswj pa luam yeeb, xav txog cov kev daws teeb meem synergistic hauv qab no:

• Cov Tshuaj Molybdenum(piv txwv li, zinc molybdate, molybdenum trioxide): Zoo dua li zinc borate tab sis kim dua; pom zoo kom sib xyaw nrog zinc borate (piv txwv li, zinc borate: zinc molybdate = 2:1).
• Aluminium/Magnesium HydroxideYuav tsum tau muaj kev thauj khoom ntau (20-40 phr), uas yuav cuam tshuam rau cov khoom siv kho tshuab ntawm epoxy - kho kom zoo.

3. Kev Hloov Kho Cov Qauv Uas Pom Zoo

Xav tias daim ntawv qhia thawj yogtxhuas hypophosphite + MCA, ntawm no yog cov lus qhia txog kev ua kom zoo dua (raws li 100 qhov epoxy resin):

Xaiv 1: Ntxiv Zinc Borate ncaj qha

• Aluminium hypophosphite: Txo ntawm 20-30 phr rau15-25 teev
• MCA: Txo ntawm 10-15 phr rau8-12 teev
• Zinc borate: Ntxiv5-15 teev(pib kuaj thaum 10 teev sawv ntxov)
• Tag nrho cov ntsiab lus nplaim taws: Khaws cia rau30-40 teev(tsis txhob siv ntau dhau uas cuam tshuam rau kev ua haujlwm ntawm cov nplaum).

Kev Xaiv 2: Zinc Borate + Zinc Molybdate Synergy

• Aluminium hypophosphate:15-20 teev
• MCA:5-10 teev
• Zinc borate:8-12 teev
• Zinc molybdate:4-6 phr
• Tag nrho cov ntsiab lus nplaim taws:30-35 teev.

4. Cov Kev Ntsuas Kev Pom Zoo Tseem Ceeb

• Kev Tiv Thaiv Hluav Taws Kub: UL-94 hlawv ntsug, kev ntsuam xyuas LOI (lub hom phiaj: V-0 lossis LOI >30%).
• Kev Haus Luam Yeeb CeevSiv lub tshuab ntsuas pa luam yeeb (piv txwv li, NBS lub tshuab ntsuas pa luam yeeb) los sib piv qhov txo qis ntawm Smoke Density Rating (SDR).
• Cov Khoom Siv Kho Tshuab: Xyuas kom lub zog tensile thiab lub zog adhesion ua tau raws li qhov yuav tsum tau ua tom qab kho.
• Kev ua tau zoo: Paub tseeb tias cov tshuaj tua hluav taws sib xyaw ua ke yam tsis muaj kev cuam tshuam rau viscosity lossis lub sijhawm kho.

5. Tej Yam Yuav Tsum Xav Txog

• Kev Tswj Qhov Loj ntawm Cov Khoom Me MeXaiv cov zinc borate me me (piv txwv li, qhov loj me ntawm cov khoom me me <1 μm) los txhim kho kev sib kis.
• Kev Hloov Kho Qhov Chaw: Kho cov zinc borate nrog cov neeg sawv cev silane coupling kom txhim kho kev sib raug zoo nrog epoxy resin.
• Kev Ua Raws Cai: Xyuas kom tseeb tias cov tshuaj tua hluav taws uas xaiv tau ua raws li RoHS, REACH, thiab lwm yam kev cai.

6. Piv txwv kev tsim qauv (Siv los ua piv txwv)

7. Cov Lus Qhia Luv Luv

• Zinc borate yog ib qho kev xaiv zoo rau kev txo cov pa luam yeeb. Pom zoo kom ntxiv10-15 teevthaum txo cov ntsiab lus ntawm txhuas hypophosphite / MCA.
• Rau kev txo pa luam yeeb ntxiv, sib tov nrog cov tshuaj molybdenum (piv txwv li,4-6 phr).
• Kev kuaj xyuas qhov tseeb yog qhov tsim nyog los sib npaug qhov ua kom tsis txhob muaj hluav taws, kev tswj pa luam yeeb, thiab cov khoom siv kho tshuab.
