Cov qauv siv rau cov tshuaj nplaum hluav taws xob acrylic uas tsis muaj halogen
Hauv cov tshuab acrylic uas siv dej, qhov ntxiv ntawm aluminium hypophosphite (AHP) thiab zinc borate (ZB) yuav tsum txiav txim siab raws li cov kev cai tshwj xeeb ntawm daim ntawv thov (xws li qhov ntsuas hluav taws kub, qhov tuab ntawm txheej, qhov yuav tsum tau ua kom lub cev muaj zog, thiab lwm yam) thiab lawv cov teebmeem synergistic. Hauv qab no yog cov lus qhia dav dav thiab cov qauv siv:
I. Cov Nqi Ntxiv Pib
Rooj: Cov Lus Qhia Ntxiv thiab Cov Lus Piav Qhia Txog Cov Khoom Uas Tiv Thaiv Hluav Taws
| Hom nplaim taws | Cov Lus Qhia Ntxiv (wt%) | Kev piav qhia |
| Aluminium Hypophosphite (AHP) | 5% ~ 20% | Cov tshuaj tua hluav taws uas muaj phosphorus ua ke; ua kom cov hluav taws kub tsis kam zoo thiab sib npaug nrog kev sib haum xeeb ntawm lub kaw lus (yog tias muaj ntau dhau yuav cuam tshuam rau cov khoom siv kho tshuab). |
| Zinc Borate (ZB) | 2% ~ 10% | Synergistic enhancer; tuaj yeem txo qhov ntxiv tag nrho thaum ua ke nrog AHP (xav tau cov feem pua ntau dua yog tias siv ib leeg). |
II. Kev Txhim Kho Cov Piv Txwv Sib Xyaws
- Cov Piv Txwv Sib Xyaws Ib Txwm Muaj:
- AHP:ZB = 2:1 ~ 4:1(piv txwv li, 15% AHP + 5% ZB, tag nrho 20%).
- Kho cov piv txwv los ntawm kev sim, piv txwv li:
- Kev thov kom muaj hluav taws kub siab:AHP 15% ~ 20%, ZB 5% ~ 8%.
- Cov khoom sib npaug ntawm lub cev:AHP 10% ~ 15%, ZB 3% ~ 5%.
- Cov teebmeem synergistic:
- Zinc borate ua rau muaj kev tiv thaiv hluav taws los ntawm:
- Kev ruaj khov ntawm cov char (cuam tshuam nrog aluminium phosphate uas tsim los ntawm AHP).
- Tso cov dej khi kom nqus tau cua sov thiab ua kom cov pa roj uas yooj yim hlawv tawm.
III. Cov Kauj Ruam Txheeb Xyuas Kev Sim
- Kev Ntsuas Kauj Ruam:
- Kev kuaj xyuas tus kheej:Ua ntej, soj ntsuam AHP (5%~20%) lossis ZB (5%~15%) sib cais rau qhov tsis kam hluav taws (UL-94, LOI) thiab kev ua tau zoo ntawm txheej (kev nplaum, qhov nyuaj, kev tiv dej).
- Kev ua kom zoo dua qub:Tom qab xaiv tus nqi AHP pib, maj mam ntxiv ZB (piv txwv li, 3% txog 8% thaum AHP yog 15%) thiab saib xyuas kev txhim kho ntawm kev tiv thaiv hluav taws thiab cov kev mob tshwm sim.
- Cov Cim Qhia Txog Kev Ua Tau Zoo:
- Kev tiv thaiv hluav taws kub:LOI (lub hom phiaj ≥28%), UL-94 qib (V-0/V-1), pa luam yeeb ceev.
- Cov khoom siv lub cev:Kev tsim zaj duab xis, kev nplaum (ASTM D3359), kev tiv thaiv dej (tsis muaj kev tawg tom qab 48 teev immersion).
IV. Cov Kev Xav Tseem Ceeb
- Kev Ruaj Ntseg ntawm Kev Tawg:
- AHP yog hygroscopic - ua ntej ziab lossis siv cov qauv hloov kho ntawm qhov chaw.
- Siv cov tshuaj dispersants (piv txwv li, BYK-190, TEGO Dispers 750W) los txhim kho kev sib npaug thiab tiv thaiv kev poob qis.
- Kev Sib Haum Xeeb ntawm pH:
- Cov txheej txheem acrylic uas siv dej feem ntau muaj pH ntawm 8–9; xyuas kom AHP thiab ZB ruaj khov (zam tsis txhob hydrolysis lossis decomposition).
- Kev Ua Raws Cai:
- AHP yuav tsum ua tau raws li cov cai RoHS uas tsis muaj halogen; ZB yuav tsum siv cov qib tsis muaj hlau hnyav.
V. Lwm Txoj Kev Los Yog Kev Daws Teeb Meem Ntxiv
- Melamine Polyphosphate (MPP):Yuav ua rau muaj kev tiv thaiv hluav taws kub ntxiv thaum muab sib xyaw nrog AHP (piv txwv li, 10% AHP + 5% MPP + 3% ZB).
- Nano Flame Retardants:Nano-qib ZB (ntxiv txo qis rau 1% ~ 3%) lossis txheej ob chav hydroxides (LDH) rau kev txhim kho cov teebmeem thaiv.
VI. Cov Lus Qhia Txog Kev Siv
- Cov qauv pib:AHP 10%~15% + ZB 3%~5% (tag nrho 13%~20%), ces ua kom zoo dua.
- Txoj kev lees paub:Sim cov qauv me me rau LOI thiab UL-94 thaum soj ntsuam cov khoom siv kho tshuab.
