Kedu otu esi ebelata njupụta anwụrụ ọkụ maka nrapado epoxy nwere AHP na MCA na-ere ọkụ?

Mgbakwunye nke aluminom hypophosphite na MCA na nrapado epoxy na-ebute oke anwụrụ ọkụ. Iji zinc borate iji belata njupụta anwụrụ ọkụ na ikuku ga-ekwe omume, mana usoro dị adị kwesịrị ka emeziwanye ya maka oke.

1. Usoro mkpochapụ anwụrụ ọkụ nke Zinc Borate

Zinc borate bụ ihe na-egbochi anwụrụ ọkụ yana synergist na-egbochi ọkụ. Usoro ya gụnyere:

• Nkwalite Char Formation: Na-etolite akwa cha cha n'oge ọkụ, na-ekewa ikuku oxygen na okpomọkụ, na ibelata ntọhapụ gas na-ere ọkụ.
• Mgbochi anwụrụ ọkụ: Catalyzes cross-njikọ mmeghachi omume iji belata anwụrụ irighiri ọgbọ, iweda anwụrụ njupụta (karịsịa irè maka polymers dị ka epoxy).
• Mmetụta Synergistic: Na-eme ka ire ọkụ na-adịgide adịgide mgbe ejikọtara ya na phosphorus dabeere (dịka, aluminom hypophosphite) na nitrogen dabeere (dịka, MCA) ọkụ retardants.

2. Nhọrọ ọzọ ma ọ bụ mgbakwunye anwụrụ ọkụ

Maka inwekwu nkwalite nke nkwụsị anwụrụ ọkụ, tụlee ihe ngwọta synergistic ndị a:

• Ngwakọta molybdenum(dịka ọmụmaatụ, zinc molybdate, molybdenum trioxide): Dị irè karịa zinc borate mana ọnụ ahịa; akwadoro ka ịgwakọta ya na zinc borate (dịka ọmụmaatụ, zinc borate: zinc molybdate = 2: 1).
• Aluminom/Magnesium Hydroxide: Na-achọ ibu ibu dị elu (20-40 phr), nke nwere ike imetụta ihe eji arụ ọrụ epoxy-dozie nke ọma.

3. Ndozi nhazi nke akwadoro

Na-eche na nhazi mbụ bụaluminom hypophosphite + MCA, ebe a bụ ntụziaka kachasị mma (dabere na 100 akụkụ epoxy resin):

Nhọrọ 1: Mgbakwunye Zinc Borate ozugbo

• Aluminom hypophosphite: belata site na 20-30 phr ruo15-25 nkeji
• MCA: Wedata site na 10-15 phr ruo8-12 nkeji
• Zinc borate: Tinye5-15 nkeji(malite ule na 10phr)
• Mkpokọta ọdịnaya na-egbochi ire ọkụ: Debe na30-40 phr(zere oke oke na-emetụta arụmọrụ nrapado).

Nhọrọ 2: Zinc Borate + Zinc Molybdate Synergy

• Aluminom hypophosphite:15-20 phr
• MCA:5-10 nkeji
• Zinc borate:8-12 nkeji
• Zinc molybdate:4-6 nkeji
• Mkpokọta ọdịnaya na-egbochi ire ọkụ:30-35 nkeji.

4. Metrics nkwado isi

• Ịkwụsị ire ọkụ: UL-94 vetikal ọkụ, LOI ule (lekwasịrị: 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 ọkwa njupụta anwụrụ ọkụ (SDR).
• Ihe eji arụ ọrụ: Gbaa mbọ hụ na ike nkwụsị na ike adhesion na-emezu ihe achọrọ mgbe ọ gwọchara ya.
• Nhazi: Kwenye n'otu n'otu mgbasa nke ire ere na-enweghị emetụta viscosity ma ọ bụ ọgwụgwọ oge.

5. Ntụle

• Njikwa nha urughuru: Họrọ maka nano-sized zinc borate (dịka ọmụmaatụ, nha nha <1 μm) iji melite mgbasa.
• Mgbanwe elu: Jiri ihe na-ejikọta silane na-emeso borate zinc iji kwalite ndakọrịta na resin epoxy.
• Nrube isi n'usoro: Gbaa mbọ hụ na ndị na-ere ọkụ ahọpụtara ga-ezute RoHS, REACH na ụkpụrụ ndị ọzọ.

6. Ntụle Nlereanya (Ntụaka)

7. Nchịkọta

• Zinc borate bụ nhọrọ dị irè maka ibelata ikuku anwụrụ ọkụ. Na-akwado ịgbakwunye10-15 phrebe a na-ebelata ọdịnaya aluminom hypophosphite/MCA nke ọma.
• Maka nkwụchikwu anwụrụ ọkụ, gwakọta ya na ogige molybdenum (dịka ọmụmaatụ,4-6 nkeji).
• Nnwale nnwale dị mkpa iji dozie nkwụchi ọkụ, nkwụsị anwụrụ ọkụ, na akụrụngwa akụrụngwa.
