Kodi mungachepetse bwanji kuchuluka kwa utsi wa epoxy glue pogwiritsa ntchito AHP ndi MCA yoletsa moto?

Kuwonjezera kwa aluminiyamu hypophosphite ndi MCA ku epoxy glue kumapangitsa kuti utsi utuluke kwambiri. Kugwiritsa ntchito zinc borate kuti muchepetse kuchuluka kwa utsi ndi kutulutsa utsi n'kotheka, koma njira yomwe ilipo iyenera kukonzedwa bwino kuti igwirizane ndi chiŵerengerocho.

1. Njira Yochepetsera Utsi ya Zinc Borate

Zinc borate ndi mankhwala othandiza kwambiri oletsa utsi komanso oletsa moto. Njira zake ndi monga:

• Kukwezedwa kwa Mapangidwe a Char: Amapanga mpweya wokhuthala kwambiri panthawi yoyaka, amalekanitsa mpweya ndi kutentha, komanso amachepetsa kutulutsa mpweya woyaka.
• Kuletsa Utsi: Imalimbikitsa zochitika zolumikizana kuti ichepetse kupanga tinthu ta utsi, kuchepetsa kuchuluka kwa utsi (makamaka yogwira ntchito pa ma polima monga epoxy).
• Zotsatira Zogwirizana: Zimawonjezera kuchedwa kwa moto zikaphatikizidwa ndi zinthu zochokera ku phosphorous (monga aluminium hypophosphite) ndi zinthu zochokera ku nitrogen (monga MCA) zomwe zimaletsa moto.

2. Zoletsa Utsi Zina Kapena Zowonjezera

Kuti muwonjezere kukhathamiritsa kwa utsi, ganizirani njira zotsatirazi zogwirizanirana:

• Ma Molybdenum Compounds(monga, zinc molybdate, molybdenum trioxide): Yogwira ntchito bwino kuposa zinc borate koma yokwera mtengo; imalimbikitsidwa kusakaniza ndi zinc borate (monga, zinc borate: zinc molybdate = 2:1).
• Aluminiyamu/Magnesium Hydroxide: Imafuna kunyamula katundu wambiri (20-40 phr), zomwe zingakhudze momwe epoxy imagwirira ntchito—sinthani mosamala.

3. Zosintha Zoyenera Kukonza

Kuganiza kuti kapangidwe koyambirira ndialuminiyamu hypophosphite + MCA, nayi malangizo okonza bwino (kutengera magawo 100 a epoxy resin):

Njira 1: Kuwonjezera Zinc Borate Mwachindunji

• Aluminium hypophosphite: Chepetsani kuchokera pa 20-30 phr mpakaMaola 15-25
• MCA: Chepetsani kuchokera pa 10-15 ph kufika paMagawo 8-12
• Zinc borate: OnjezaniMagawo 5-15(yambani kuyesa pa 10 phr)
• Zonse zomwe zimaletsa moto: Khalani pa30-40 ph(pewani kuchuluka kwambiri komwe kungakhudze magwiridwe antchito a zomatira).

Njira yachiwiri: Zinc Borate + Zinc Molybdate Synergy

• Hypophosphate ya aluminiyamu:Maola 15-20
• MCA:Magawo 5-10
• Zinc borate:Magawo 8-12
• Zinc molybdate:Magawo 4-6
• Zonse zomwe zimaletsa moto:30-35 ph.

4. Ziwerengero Zofunikira Zotsimikizira

• Kubwerera kwa Moto: Kuwotcha koyima kwa UL-94, mayeso a LOI (chandamale: V-0 kapena LOI >30%).
• Kuchuluka kwa utsiGwiritsani ntchito choyezera kuchuluka kwa utsi (monga chipinda cha utsi cha NBS) kuti muyerekezere kuchepetsa kuchuluka kwa utsi (SDR).
• Katundu wa MakinaOnetsetsani kuti mphamvu yokoka ndi mphamvu yomatira zikukwaniritsa zofunikira pambuyo pochira.
• Kuthekera kwa kukonza: Tsimikizirani kufalikira kwa zinthu zoletsa moto mofanana popanda kusokoneza kukhuthala kapena nthawi yoziziritsa.

5. Zofunika Kuganizira

• Kulamulira Kukula kwa TinthuSankhani nano-sized zinc borate (monga, tinthu tating'onoting'ono <1 μm) kuti muwongolere kufalikira.
• Kusintha kwa pamwamba: Thirani zinc borate ndi silane coupling agent kuti muwonjezere kugwirizana ndi epoxy resin.
• Kutsatira MalamuloOnetsetsani kuti zinthu zoletsa moto zomwe zasankhidwa zikutsatira malamulo a RoHS, REACH, ndi ena.

6. Chitsanzo Chopangira (Chidziwitso)

7. Chidule

• Zinc borate ndi njira yabwino kwambiri yochepetsera utsi wotuluka. Ndibwino kuwonjezerapoMaola 10-15pamene akuchepetsa pang'ono kuchuluka kwa aluminiyamu hypophosphite/MCA.
• Kuti muchepetse utsi, sakanizani ndi mankhwala a molybdenum (monga,Magawo 4-6).
• Kutsimikizira koyesera ndikofunikira kuti pakhale kusinthasintha kwa kuchedwa kwa moto, kuletsa utsi, ndi mphamvu za makina.
