Ungawunciphisa njani umsi womsi kwi-epoxy adhesive ene-AHP kunye ne-MCA ethintela ilangabi?

Ukongezwa kwe-aluminium hypophosphite kunye ne-MCA kwi-epoxy adhesive kubangela ukukhutshwa komsi okuphezulu. Ukusebenzisa i-zinc borate ukunciphisa uxinano lomsi kunye nokukhutshwa kwawo kunokwenzeka, kodwa indlela ekhoyo kufuneka ilungiselelwe umlinganiselo.

1. Indlela yokuCima umsi yeZinc Borate

I-Zinc borate iyasebenza kakuhle ekunciphiseni umsi kwaye ikwanceda ekuthinteleni amalangatye. Iindlela zayo ziquka:

• Ukukhuthazwa koBuchule boChar: Yenza umaleko oxineneyo wetshani ngexesha lokutsha, ikhuphe ioksijini nobushushu, kwaye inciphise ukukhutshwa kwegesi evuthayo.
• Ukuthintela Umsi: Ivuselela ii-cross-linking reactions ukuze kuncitshiswe ukuveliswa kwee-smoke particles, inciphise uxinano lomsi (ingakumbi isebenza kwiipolymers ezifana ne-epoxy).
• Isiphumo sokusebenzisana: Yonyusa ukulibaziseka komlilo xa idityaniswe nezinto ezithintela umlilo ezisekelwe kwi-phosphorus (umz., i-aluminium hypophosphite) kunye nezinto ezithintela umlilo ezisekelwe kwi-nitrogen (umz., i-MCA).

2. Ezinye izinto ezithintela umsi okanye ezongezelelweyo

Ukuze kuphuculwe ngakumbi ucinezelo lomsi, cinga ngezi zisombululo zilandelayo ezisebenzisanayo:

• Iikhompawundi zeMolybdenum(umz., i-zinc molybdate, i-molybdenum trioxide): Isebenza ngcono kune-zinc borate kodwa ibiza kakhulu; kucetyiswa ukuba ixutywe ne-zinc borate (umz., i-zinc borate: i-zinc molybdate = 2:1).
• I-Aluminiyam/i-Magnesium Hydroxide: Ifuna umthwalo ophezulu (20-40 phr), nto leyo enokuchaphazela iipropati zoomatshini ze-epoxy—lungisa ngononophelo.

3. Uhlengahlengiso olucetyiswayo lweFomu

Ukucinga ukuba indlela yokuqalai-aluminium hypophosphite + i-MCA, nazi iindlela zokwenza ngcono (ezisekelwe kwi-epoxy resin eneendawo ezili-100):

Ukhetho 1: Ukongeza ngokuthe ngqo iZinc Borate

• I-aluminium hypophosphite: Yehlisa ukusuka kwi-20-30 phr ukuya kwi-15-25 phr
• I-MCA: Yehlisa ukusuka kwi-10-15 ukuya kwi-8-12 amagama
• I-borate yeZinc: Yongeza5-15 amagama(qala uvavanyo nge-10 phr)
• Umxholo opheleleyo wokurhoxisa ilangatye: Hlala apha30-40 phr(kuphephe ubuninzi obugqithisileyo obuchaphazela ukusebenza kwe-adhesive).

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

• I-hypophosphite ye-aluminiyam:15-20 phr
• I-MCA:5-10 amagama
• I-borate yeZinc:8-12 amagama
• I-Zinc molybdate:Iingcaciso ezi-4-6
• Umxholo opheleleyo wokurhoxisa ilangatye:30-35 phr.

4. IiMetriki zoQinisekiso oluPhambili

• Ukuthintela ilangatye: Ukutshisa ngokuthe nkqo kwe-UL-94, uvavanyo lwe-LOI (ithagethi: V-0 okanye i-LOI >30%).
• Ubuninzi bomsiSebenzisa isixhobo sokuvavanya uxinano lomsi (umz., igumbi lomsi le-NBS) ukuthelekisa ukuncipha koHlelo loxinano lomsi (SDR).
• Iipropati zoomatshini: Qinisekisa ukuba amandla okutsalwa kunye namandla okunamathela ayahlangabezana neemfuno emva kokunyangwa.
• Ukuqhubekeka: Qinisekisa ukusasazeka okufanayo kwezinto ezithintela ilangatye ngaphandle kokuchaphazela ukuxinana okanye ixesha lokuphiliswa.

5. Izinto ekufuneka ziqwalaselwe

• Ulawulo lobungakanani beenxalenyeKhetha i-zinc borate enobukhulu obuncinci (umz., ubungakanani bamasuntswana <1 μm) ukuphucula ukusasazeka.
• Ukuguqulwa komphezulu: Phatha i-zinc borate nge-silane coupling agent ukuze ulungelelane ne-epoxy resin.
• Ukuthotyelwa kweMithetho: Qinisekisa ukuba izinto ezithintela ilangatye ezikhethiweyo ziyahlangabezana nemigaqo yeRoHS, REACH, kunye neminye.

6. Umzekelo Wokwenziwa (Isalathiso)

7. Isishwankathelo

• I-Zinc borate lukhetho olusebenzayo lokunciphisa ukukhutshwa komsi. Ndicebisa ukuba wongeze10-15 iphrngelixa kunciphisa ngokuphakathi umxholo we-aluminium hypophosphite/MCA.
• Ukuze unciphise ngakumbi umsi, xuba neekhompawundi ze-molybdenum (umz.,Iingcaciso ezi-4-6).
• Ukuqinisekiswa kovavanyo kuyimfuneko ukulinganisela ukuthintela ilangatye, ukucima umsi, kunye neempawu zoomatshini.
