Kedu otu esi ebelata njupụta anwụrụ ọkụ maka ihe mgbakwunye epoxy nwere ihe na-egbochi ọkụ AHP na MCA?

Mgbakwunye nke aluminom hypophosphite na MCA na ihe mgbakwunye epoxy na-eme ka anwụrụ ọkụ dị elu. O kwere omume iji zinc borate belata njupụta anwụrụ ọkụ na mwepụta, mana ọ dị mkpa ka a hazie usoro dị ugbu a maka oke ya.

1. Usoro Mgbochi Anwụrụ ọkụ nke Zinc Borate

Zinc borate bụ ọgwụ na-ebelata anwụrụ ọkụ nke ọma ma na-egbochi ire ọkụ. Usoro ya gụnyere:

• Nkwalite Nhazi Char: Na-emepụta oyi akwa char dị oke njọ n'oge ọkụ, na-ekewapụ ikuku oxygen na okpomọkụ, ma na-ebelata mwepụta gas na-ere ọkụ.
• Mgbochi Anwụrụ: Na-akpali mmeghachi omume njikọ iji belata mmepụta nke ihe anwụrụ ọkụ, na-ebelata njupụta anwụrụ ọkụ (karịsịa irè maka polymers dị ka epoxy).
• Mmetụta Mmekọrịta: Na-eme ka ire ọkụ ghara ịdị irè ma ọ bụrụ na ejikọtara ya na ihe ndị na-egbochi ire ọkụ nke sitere na phosphorus (dịka ọmụmaatụ, aluminom hypophosphite) na ihe ndị na-egbochi ire ọkụ nke sitere na nitrogen (dịka ọmụmaatụ, MCA).

2. Ihe Mgbochi Anwụrụ ọkụ ma ọ bụ ihe mgbakwunye

Maka ime ka mma nke iwepụ anwụrụ ọkụ dịkwuo mma, tụlee ngwọta ndị a na-eme ka a na-eme ka anwụrụ ọkụ ghara ịdị mma:

• Ihe Ndị Dị na Molybdenum(dịka ọmụmaatụ, zinc molybdate, molybdenum trioxide): Ọ dị irè karịa zinc borate mana ọ dị oke ọnụ; a na-atụ aro ka agwakọta ya na zinc borate (dịka ọmụmaatụ, zinc borate: zinc molybdate = 2:1).
• Aluminom/Magnesium Hydroxide: Ọ chọrọ nnukwu ibu (20-40 phr), nke nwere ike imetụta njirimara igwe nke epoxy - jiri nlezianya gbanwee ya.

3. Mgbanwe Nhazi Akwadoro

Echere na usoro mbụ ahụ bụaluminom hypophosphite + MCA, lee ntuziaka maka imeziwanye ihe (dabere na akụkụ 100 nke epoxy resin):

Nhọrọ nke 1: Mgbakwunye Zinc Borate ozugbo

• Aluminom hypophosphite: Belata site na 20-30 hr ruo15-25 ph
• MCA: Belata site na 10-15 phr ruo8-12 phr
• Zinc borate: Tinye5-15 phr(malite nnwale na elekere iri nke ụtụtụ)
• Mkpokọta ọdịnaya nke ihe na-egbochi ire ọkụ: Nọgide na30-40 ph(zere oke oke nke na-emetụta arụmọrụ nrapado).

Nhọrọ nke 2: Njikọ Zinc Borate + Zinc Molybdate

• Aluminom hypophosphite:15-20 ph
• MCA:5-10 phr
• Borate zinc:8-12 phr
• Zinc molybdate:4-6 phr
• Mkpokọta ọdịnaya nke ihe na-egbochi ire ọkụ:30-35 ph.

4. Usoro Nnwale Isi

• Nkwụsị ire ọkụ: ọkụ kwụ ọtọ nke UL-94, ule LOI (ihe mgbaru ọsọ: V-0 ma ọ bụ LOI >30%).
• Njupụta anwụrụ ọkụ: Jiri ihe nnwale njupụta anwụrụ ọkụ (dịka ọmụmaatụ, ụlọ anwụrụ ọkụ NBS) iji tụnyere mbelata na Njupụta anwụrụ ọkụ (SDR).
• Njirimara Mekaniki: Hụ na ike nrụgide na ike njikọta na-emezu ihe achọrọ mgbe a gwọrọ ya.
• Nhazi: Kwenye na mgbasa nke ihe ndị na-egbochi ire ọkụ na-agbasa n'otu ebe n'enweghị mmetụta nke viscosity ma ọ bụ oge ọgwụgwọ.

5. Ihe Ndị A Ga-atụle

• Njikwa Nha Ngwugwu: Họrọ zinc borate nke nha nano (dịka ọmụmaatụ, nha ihe na-erughị 1 μm) iji melite mgbasa.
• Mgbanwe Elu: Jiri ihe na-ejikọ silane gwọọ zinc borate iji mee ka ọ dakọọ na epoxy resin.
• Nrubeisi Iwu: Hụ na ihe ndị na-egbochi ire ọkụ ahọpụtara na-emezu RoHS, REACH, na iwu ndị ọzọ.

6. Nhazi Ihe Nlereanya (Ntụaka)

7. Nchịkọta

• Zinc borate bụ nhọrọ dị irè maka ibelata mwepụta anwụrụ ọkụ. A na-atụ aro ka ịtinye ya na ihe ndị ọzọ.10-15 phrebe ọ na-ebelata ọdịnaya aluminom hypophosphite/MCA nke ọma.
• Maka igbochi anwụrụ ọkụ ọzọ, gwakọta ya na ihe ndị metụtara molybdenum (dịka ọmụmaatụ,4-6 phr).
• Nnwale nnwale dị mkpa iji dozie mbelata ire ọkụ, mbelata anwụrụ ọkụ, na njirimara igwe.
