Mokhoa oa ho fokotsa bongata ba mosi bakeng sa sekhomaretsi sa epoxy se nang le AHP le MCA e thibelang malakabe?

Ho eketsoa ha aluminium hypophosphite le MCA ho sekhomaretsi sa epoxy ho fella ka ho ntshuwa ha mosi o mongata. Ho sebedisa zinc borate ho fokotsa bongata ba mosi le ho ntshuwa ha mosi ho a kgoneha, empa sebopeho se seng se ntse se le teng se hloka ho ntlafatswa bakeng sa karolelano.

1. Mokhoa oa ho Thibela Mosi oa Zinc Borate

Zinc borate ke sesebelisoa se sebetsang hantle sa ho thibela mosi le ho kopanya lintho tse thibelang malakabe. Mekhoa ea eona e kenyelletsa:

• Khothaletso ea ho Hlahisa Char: E etsa lera le teteaneng la char nakong ea ho cha, e arola oksijene le mocheso, 'me e fokotsa ho lokolloa ha khase e tukang.
• Thibelo ea Mosi: E hlohlelletsa dikarabelo tsa ho hokahanya ho fokotsa tlhahiso ya dikarolwana tsa mosi, e fokotsa bongata ba mosi (haholo-holo e sebetsang bakeng sa di-polymer tse kang epoxy).
• Phello ea ho Kopanela: E eketsa ho tiea ha mollo ha e kopantsoe le lintho tse thibelang mollo tse thehiloeng ho phosphorus (mohlala, aluminium hypophosphite) le tse thehiloeng ho nitrogen (mohlala, MCA).

2. Lintho tse ling tse thibelang mosi kapa tse tlatsetsang

Bakeng sa ntlafatso e eketsehileng ea ho thibela mosi, nahana ka litharollo tse latelang tse sebetsang hammoho:

• Metswako ea Molybdenum(mohlala, zinc molybdate, molybdenum trioxide): E sebetsa hantle ho feta zinc borate empa e bitsa chelete e ngata; e kgothaletswa ho kopanya le zinc borate (mohlala, zinc borate: zinc molybdate = 2:1).
• Aluminium/Magnesium Hydroxide: E hloka mojaro o phahameng (20-40 phr), e leng se ka amang thepa ea mechini ea epoxy—e lokise ka hloko.

3. Liphetoho tse khothaletsoang tsa ho etsa moralo

Ho nka hore sebopeho sa pele kealuminium hypophosphate + MCA, tsena ke litaelo tsa ntlafatso (ho latela likarolo tse 100 tsa epoxy resin):

Khetho ea 1: Ho Eketsoa ka ho Toba ha Zinc Borate

• Aluminium hypophosphite: Fokotsa ho tloha ho 20-30 phr ho ea hoLihora tse 15-25
• MCA: Fokotsa ho tloha ho 10-15 ho ea hoLipuo tse 8-12
• Borate ea Zinki: EketsaLipuo tse 5-15(qala ho etsa liteko ha u le lihora tse 10)
• Kakaretso ea dikahare tse thibelang malakabe: Boloka hoLihora tse 30-40(qoba bongata bo feteletseng bo amang ts'ebetso ea sekhomaretsi).

Khetho ea 2: Sinki Borate + Sinki Molybdate Synergy

• Hypophosphate ea aluminium:Lihora tse 15-20
• MCA:Lipuo tse 5-10
• Borate ea zinki:Lipuo tse 8-12
• Molybdate ea zinki:Lipuo tse 4-6
• Kakaretso ea dikahare tse thibelang malakabe:Lihora tse 30-35.

4. Litekanyo tsa Bohlokoa tsa Netefatso

• Ho Thibela Lelakabe: Ho chesa ka ho otloloha ha UL-94, liteko tsa LOI (sepheo: V-0 kapa LOI >30%).
• Botebo ba Mosi: Sebelisa sesebelisoa sa ho lekola bongata ba mosi (mohlala, kamore ea mosi ea NBS) ho bapisa phokotso ea Tekanyo ea Bongata ba Mosi (SDR).
• Matlotlo a Mekaniki: Netefatsa hore matla a ho tsikinyeha le matla a ho khomarela li fihlela litlhoko kamora ho fola.
• Ho sebetsa habonolo: Netefatsa ho hasana ho ts'oanang ha lintho tse thibelang malakabe ntle le ho ama ho teteana kapa nako ea ho fola.

5. Lintho tse lokelang ho nahanoa

• Taolo ea Boholo ba Likaroloana: Khetha borate ea zinki e boholo ba nano (mohlala, boholo ba likaroloana <1 μm) ho ntlafatsa ho hasana.
• Phetoho ea Bokaholimo: Tšoara borate ea zinki ka sesebelisoa sa ho kopanya sa silane ho ntlafatsa ho lumellana le resin ea epoxy.
• Ho Latela MelaoNetefatsa hore lintho tse thibelang malakabe tse khethiloeng li fihlela melaoana ea RoHS, REACH le e meng.

6. Mohlala oa ho qapa (Tlhahiso)

7. Kakaretso

• Zinc borate ke khetho e sebetsang bakeng sa ho fokotsa mosi o tsoang. Khothalletsa ho eketsaLihora tse 10-15ha ka nako e tšoanang ho fokotsa ka tekanyo tekanyo ea aluminium hypophosphite/MCA.
• Bakeng sa ho thibela mosi haholoanyane, kopanya le metsoako ea molybdenum (mohlala,Lipuo tse 4-6).
• Netefatso ea liteko ea hlokahala ho leka-lekanya ho tiea ha lelakabe, ho tima mosi le litšobotsi tsa mechini.
