Nzira yekudzikisa sei hutsi hwehutsi hwe epoxy adhesive ine flame retardant AHP uye MCA?

Kuwedzerwa kwealuminium hypophosphite uye MCA kune epoxy adhesive inoguma mukubuda kwehutsi hwepamusoro. Kushandisa zinc borate kuderedza kuwanda kwehutsi nekubuda kwayo kunogoneka, asi magadzirirwo aripo anofanira kukwenenzverwa pachiyero.

1. Smoke Suppression Mechanism yeZinc Borate

Zinc borate inonyatso kudzvanya utsi uye murazvo-retardant synergist. Maitiro ayo anosanganisira:

• Char Formation Promotion: Inoumba dense char layer panguva yekupisa, inoparadzanisa okisijeni uye kupisa, uye kuderedza kuburitswa kwegasi rinobvira.
• Smoke Inhibition: Inokonzeresa maitiro ekubatanidza kudzikamisa kugadzirwa kwehutsi, kudzikisa hutsi hwehutsi (kunyanya inoshanda kune mapolymers senge epoxy).
• Synergistic Effect: Inovandudza kunonoka kwemurazvo kana yasanganiswa nephosphorus-based (eg, aluminum hypophosphite) uye nitrogen-based (eg, MCA) inodzoreredza moto.

2. Alternative or Supplementary Smoke Suppressants

Kuti uwedzere kukwidziridzwa kwehutsi, funga zvinotevera synergistic mhinduro:

• Molybdenum Compounds(semuenzaniso, zinc molybdate, molybdenum trioxide): Inoshanda kupfuura zinc borate asi inodhura; inokurudzirwa kusanganisa ne zinc borate (eg, zinc borate : zinc molybdate = 2:1).
• Aluminium / Magnesium Hydroxide: Inoda kurodha kwepamusoro (20-40 phr), iyo inogona kukanganisa epoxy's mechanical properties-chinja nekuchenjerera.

3. Yakakurudzirwa Magadzirirwo Ekugadzirisa

Tichifunga kuti kugadzirwa kwepakutanga ndikoaluminium hypophosphite + MCA, heano maitiro ekugadzirisa (zvichienderana nezvikamu zana epoxy resin):

Sarudzo 1: Yakananga Kuwedzera kweZinc Borate

• Aluminium hypophosphite: Deredza kubva pa20-30 phr kusvika15-25 ph
• MCA: Deredza kubva ku10-15 phr kusvika8-12 pr
• Zinc borate: Wedzera5-15 pr(tanga kuyedza pa10 phr)
• Total flame retardant content: Ramba uripo30-40 phr(dzivisa kuwanda kwehuwandu hunokanganisa kuita kwekunamatira).

Sarudzo 2: Zinc Borate + Zinc Molybdate Synergy

• Aluminium hypophosphite:15-20 pr
• MCA:5-10 pr
• Zinc borate:8-12 pr
• Zinc molybdate:4-6 pr
• Total flame retardant content:30-35 phr.

4. Key Validation Metrics

• Flame Retardancy: UL-94 vertical burning, LOI miedzo (chinangwa: V-0 kana LOI> 30%).
• Smoke Density: Shandisa chiutsi density tester (semuenzaniso, NBS chiutsi chamber) kuenzanisa kuderedzwa muSmoke Density Rating (SDR).
• Mechanical Properties: Ita shuwa kusimba kwekusimba uye kusimba kwekunamatira kunosangana nezvinodiwa mushure mekurapa.
• Processability: Simbisa kupararira kweyunifomu yezvinodzosa moto pasina kukanganisa viscosity kana kurapa nguva.

5. Mafungiro

• Particle Saizi Kudzora: Sarudza nano-sized zinc borate (eg, particle size <1 μm) kuvandudza kupararira.
• Surface Modification: Ropa zinc borate ne silane coupling agent kuti uwedzere kuenderana ne epoxy resin.
• Regulatory Compliance: Ita shuwa kuti zvakasarudzwa zvinodzosa moto zvinosangana neRoHS, REACH, nemimwe mitemo.

6. Kugadzira Muenzaniso (Reference)

7. Pfupiso

• Zinc borate isarudzo inoshanda yekudzikisa kuburitsa utsi. Recommended kuwedzera10-15 prnepo ichidzikisa zvine mwero aluminium hypophosphite/MCA zvemukati.
• Kuti uwedzere kudzvinyirira utsi, sanganisa ne molybdenum makomisheni (semuenzaniso,4-6 pr).
• Kusimbisa kwekuyedza kwakakosha kuenzanisa kudzoreredza kwemoto, kudzvanywa kweutsi, uye michina zvivakwa.
