Fomula yofotokozera yoletsa moto yopanda halogen ya zomatira zamagetsi za acrylic zochokera m'madzi
Mu makina a acrylic okhala ndi madzi, kuchuluka kwa aluminium hypophosphite (AHP) ndi zinc borate (ZB) kuyenera kutsimikiziridwa kutengera zofunikira zinazake zogwiritsidwa ntchito (monga kuchedwa kwa moto, makulidwe a kupaka, zofunikira pakugwira ntchito kwa thupi, ndi zina zotero) ndi zotsatira zake zogwirizana. Nazi malingaliro ndi mitundu yofotokozera:
I. Zowonjezera Zowonjezera Zoyambira
Tebulo: Zowonjezera ndi Mafotokozedwe Oyenera Oletsa Moto
| Mtundu Wobweza Moto | Kuwonjezera Koyenera (wt%) | Kufotokozera |
| Aluminium Hypophosphite (AHP) | 5%~20% | Choletsa moto chokhala ndi phosphorous; gwirizanitsani magwiridwe antchito a choletsa moto ndi momwe makina amagwirira ntchito (kuchuluka kwambiri kungakhudze mphamvu za makina). |
| Zinc Borate (ZB) | 2%~10% | Chowonjezera cha synergistic; chingachepetse kuwonjezera konse ngati chikaphatikizidwa ndi AHP (kuchuluka kofunikira ngati chikugwiritsidwa ntchito chokha). |
II. Kukonza Ma Ratio Ophatikizana
- Ma Ratio Ofanana a Pawiri:
- AHP:ZB = 2:1 ~ 4:1(monga, 15% AHP + 5% ZB, zonse 20%).
- Sinthani ma ratios mwachiyembekezo, mwachitsanzo:
- Kufunika kwakukulu kwa kuchedwa kwa moto:AHP 15% ~ 20%, ZB 5% ~ 8%.
- Makhalidwe abwinobwino:AHP 10% ~ 15%, ZB 3% ~ 5%.
- Zotsatira Zogwirizana:
- Zinc borate imawonjezera kuchedwa kwa moto mwa:
- Kukhazikitsa mapangidwe a char (kuyanjana ndi aluminium phosphate yopangidwa ndi AHP).
- Kutulutsa madzi omangika kuti atenge kutentha ndi kuchepetsa mpweya woyaka.
III. Njira Zoyesera Zotsimikizira
- Kuyesa Kotsatira:
- Kuyesa kwa munthu payekha:Choyamba yesani AHP (5%~20%) kapena ZB (5%~15%) padera kuti muwone ngati moto uli wofooka (UL-94, LOI) komanso momwe umagwirira ntchito (kumatira, kuuma, kukana madzi).
- Kukonza bwino zinthu:Mukasankha kuchuluka kwa AHP koyambira, onjezerani pang'onopang'ono ZB (monga 3% mpaka 8% pamene AHP ili 15%) ndikuwona kusintha kwa kuchedwa kwa moto ndi zotsatira zake zoyipa.
- Zizindikiro Zofunikira za Magwiridwe Antchito:
- Kulephera kwa moto:LOI (cholinga ≥28%), UL-94 rating (V-0/V-1), kuchuluka kwa utsi.
- Kapangidwe ka thupi:Kupanga filimu, kumamatira (ASTM D3359), kukana madzi (palibe delamination pambuyo pomiza kwa maola 48).
IV. Mfundo Zofunika Kuziganizira
- Kukhazikika kwa Kubalalika:
- AHP ndi yopyapyala—youma musanagwiritse ntchito kapena gwiritsani ntchito mitundu yosinthidwa pamwamba.
- Gwiritsani ntchito zotulutsira madzi (monga BYK-190, TEGO Dispers 750W) kuti muwongolere kufanana kwa madzi ndikuletsa kusefukira kwa madzi.
- Kugwirizana kwa pH:
- Makina a acrylic okhala ndi madzi nthawi zambiri amakhala ndi pH ya 8-9; onetsetsani kuti AHP ndi ZB zimakhalabe zokhazikika (pewani hydrolysis kapena kuwola).
- Kutsatira Malamulo:
- AHP iyenera kukwaniritsa zofunikira za RoHS zopanda halogen; ZB iyenera kugwiritsa ntchito magiredi otsika a heavy-metal deficit.
V. Njira Zina kapena Zowonjezera
- Melamine Polyphosphate (MPP):Zingawonjezere kuchedwa kwa moto zikaphatikizidwa ndi AHP (monga, 10% AHP + 5% MPP + 3% ZB).
- Zoletsa Moto wa Nano:ZB ya Nano-grade (yowonjezeredwa yochepetsedwa kufika pa 1% ~ 3%) kapena ma hydroxide awiri oyikidwa (LDH) kuti zinthu ziyende bwino.
VI. Chidule cha Malangizo
- Kuyamba kwa kapangidwe kake:AHP 10%~15% + ZB 3%~5% (zonse 13%~20%), kenako konzani bwino.
- Njira yotsimikizira:Yesani zitsanzo zazing'ono za LOI ndi UL-94 pamene mukuyang'ana momwe makina amagwirira ntchito.
