Unganciphisa kanjani ukuminyana kwentuthu ye-epoxy adhesive ene-AHP ne-MCA evimbela ilangabi?

Ukwengezwa kwe-aluminium hypophosphite kanye ne-MCA ku-epoxy adhesive kuphumela ekukhishweni kwentuthu ephezulu. Ukusebenzisa i-zinc borate ukunciphisa ukuminyana kwentuthu kanye nokukhishwa kwayo kungenzeka, kodwa ukwakheka okukhona kudinga ukulungiswa ukuze kuhambisane nesilinganiso.

1. Indlela Yokucindezela Intuthu ye-Zinc Borate

I-Zinc borate iyisivimbeli esisebenzayo somusi futhi esivimbela ilangabi. Izindlela zayo zifaka:

• Ukukhuthazwa Kokwakheka Kwe-Char: Yakha ungqimba oluqinile lwe-char ngesikhathi sokusha, ihlukanise umoya-mpilo nokushisa, futhi inciphise ukukhishwa kwegesi evuthayo.
• Ukuvinjelwa Kokubhema: Ikhuthaza ukusabela kokuxhumanisa ukuze kuncishiswe ukukhiqizwa kwezinhlayiya zomusi, yehlise ubuningi bomusi (isebenza kahle kakhulu kuma-polymers afana ne-epoxy).
• Umphumela Wokubambisana: Kuthuthukisa ukuvinjelwa komlilo uma kuhlanganiswa nezinto ezivimba umlilo ezisekelwe ku-phosphorus (isb., i-aluminium hypophosphite) kanye nezinto ezivimbela umlilo ezisekelwe ku-nitrogen (isb., i-MCA).

2. Ezinye Izinto Zokucindezela Intuthu Ezihlukile Noma Ezengeziwe

Ukuze kuthuthukiswe ukucindezelwa kwentuthu, cabanga ngalezi zixazululo ezilandelayo ezihambisanayo:

• Ama-Compound e-Molybdenum(isib., i-zinc molybdate, i-molybdenum trioxide): Isebenza kahle kune-zinc borate kodwa ibiza kakhulu; kutuswa ukuthi ixutshwe ne-zinc borate (isib., i-zinc borate: i-zinc molybdate = 2:1).
• I-Aluminium/i-Magnesium Hydroxide: Kudinga umthwalo ophezulu (20-40 phr), okungase kuthinte izakhiwo zemishini ze-epoxy—lungisa ngokucophelela.

3. Ukulungiswa Okunconyiwe Kokwakheka

Uma sicabanga ukuthi indlela yokuqalai-aluminium hypophosphite + MCA, nazi iziqondiso zokwenza ngcono (ngokusekelwe ku-resin ye-epoxy enezingxenye eziyi-100):

Inketho 1: Ukwengezwa Okuqondile kwe-Zinc Borate

• I-aluminium hypophosphite: Yehlisa kusuka ku-20-30 phr kuya ku-15-25 phr
• I-MCA: Yehlisa kusuka ku-10-15 phr kuya ku-8-12 imisho
• I-Zinc borate: Engeza5-15 imisho(qala ukuhlola ku-10 phr)
• Okuqukethwe okuphelele okuvimbela ilangabi: Hlala ku-30-40 phr(gwema inani elikhulu kakhulu elithinta ukusebenza kwe-adhesive).

Inketho 2: I-Zinc Borate + I-Zinc Molybdate Synergy

• I-hypophosphite ye-aluminium:15-20 imisho
• I-MCA:5-10 imisho
• I-borate ye-zinc:8-12 imisho
• I-Zinc molybdate:Imisho engu-4-6
• Okuqukethwe okuphelele okuvimbela ilangabi:30-35 phr.

4. Amamethrikhi Okuqinisekisa Okubalulekile

• Ukuvimbela Umlilo: Ukushisa okuqondile kwe-UL-94, ukuhlolwa kwe-LOI (okuhlosiwe: V-0 noma i-LOI >30%).
• Ubuningi bentuthuSebenzisa isihloli sobuningi bentuthu (isb., igumbi lentuthu le-NBS) ukuqhathanisa ukwehla kwesilinganiso sobuningi bentuthu (i-SDR).
• Izakhiwo Zemishini: Qinisekisa ukuthi amandla okunamathela kanye namandla okunamathela ahlangabezana nezidingo ngemva kokuqina.
• Ukucutshungulwa: Qinisekisa ukusabalala okufanayo kwezinto ezivimbela ilangabi ngaphandle kokuthinta ukujiya noma isikhathi sokuphiliswa.

5. Izinto okufanele uzicabangele

• Ukulawula Usayizi WezinhlayiyanaKhetha i-zinc borate enobukhulu obuncane (isb., usayizi wezinhlayiya <1 μm) ukuze uthuthukise ukuhlakazeka.
• Ukuguqulwa Komphezulu: Phatha i-zinc borate nge-ejenti yokuhlanganisa i-silane ukuze uthuthukise ukuhambisana ne-epoxy resin.
• Ukuthobela Imithetho: Qinisekisa ukuthi izinto ezithiya umlilo ezikhethiwe ziyahlangabezana nemithetho ye-RoHS, i-REACH, kanye neminye imithetho.

6. Isibonelo Sokwenziwa (Inkomba)

7. Isifinyezo

• I-Zinc borate iyindlela ephumelelayo yokunciphisa ukukhishwa kwentuthu. Ncoma ukuthi ingezwe.10-15 imishokuyilapho kunciphisa ngokulinganisela okuqukethwe kwe-aluminium hypophosphite/MCA.
• Ukuze unciphise intuthu, hlanganisa nezinto ezisetshenziswa njenge-molybdenum (isb.,Imisho engu-4-6).
• Ukuqinisekiswa kokuhlola kuyadingeka ukuze kulinganiswe ukuvinjelwa komlilo, ukucindezela intuthu, kanye nezakhiwo zemishini.
