Nzira yekuderedza huwandu hweutsi hwe epoxy glue ine AHP neMCA inodzivirira moto?

Kuwedzerwa kwealuminium hypophosphite neMCA kune epoxy glue kunoita kuti utsi hubude zvakanyanya. Kushandisa zinc borate kuderedza huwandu hweutsi uye kuburitsa utsi zvinogoneka, asi fomura iripo inofanira kugadziriswa kuti ienderane nechiyero.

1. Nzira yekuderedza Utsi yeZinc Borate

Zinc borate inodzivirira utsi uye inodzivirira moto. Nzira dzayo dzinosanganisira:

• Kukurudzira Kuumbwa kweChar: Inoita ganda rakakora panguva yekutsva, ichibvisa okisijeni nekupisa, uye ichideredza kuburitswa kwegasi rinobvira.
• Kudziviswa kweUtsi: Inobatsira pakubatanidza zvinhu kuti ideredze kugadzirwa kwezvimedu zveutsi, ichideredza huwandu hweutsi (zvinonyanya kushanda pamapolymers akaita se epoxy).
• Mhedzisiro yekubatana: Inowedzera kunonoka kwemurazvo kana ikasanganiswa nezvinhu zvinodzivirira murazvo zvine phosphorus (semuenzaniso, aluminium hypophosphite) uye nitrogen (semuenzaniso, MCA).

2. Zvimwe kana Zvimwe Zvinodzvinyirira Utsi

Kuti utsi hudzikire zvakanyanya, funga nezvemhinduro dzinotevera dzinoshanda pamwe chete:

• Makomputa eMolybdenum(semuenzaniso, zinc molybdate, molybdenum trioxide): Inoshanda kupfuura zinc borate asi inodhura; inokurudzirwa kusanganisa ne zinc borate (semuenzaniso, zinc borate: zinc molybdate = 2:1).
• Aruminiyamu/Magnesium Hydroxide: Inoda mutoro wakawanda (20-40 phr), izvo zvinogona kukanganisa mashandiro e epoxy—gadzirisa nokungwarira.

3. Kugadziriswa Kwemagadzirirwo Anokurudzirwa

Kufunga kuti fomura yekutanga ndiyoaruminiyamu hypophosphite + MCA, heano marongero ekugadzirisa (zvichibva pa epoxy resin ine zvikamu zana):

Sarudzo 1: Kuwedzera Zinc Borate zvakananga

• Aluminum hypophosphite: Deredza kubva pa20-30 phr kusvika15-25 ph
• MCA: Deredza kubva pa10-15 phr kusvika8-12 ph.
• Zinc borate: Wedzera5-15 phr(tanga kuyedza pamaminitsi gumi)
• Zvese zvinodzora murazvo: Ramba uri pa30-40 ph(dzivisa kuwanda kwakawandisa kunokanganisa mashandiro ekunamira).

Sarudzo 2: Zinc Borate + Zinc Molybdate Synergy

• Aruminiyamu hypophosphate:15-20 ph
• MCA:5-10 phr
• Zinc borate:8-12 ph.
• Zinc molybdate:4-6 maprendi
• Zvese zvinodzora murazvo:30-35 ph.

4. Zviyero Zvikuru zvekusimbisa

• Kudzivirira Murazvo: UL-94 vertical burning, LOI tests (chinangwa: V-0 kana LOI >30%).
• Kuwanda kweutsiShandisa chinhu chinoyera huwandu hweutsi (semuenzaniso, NBS smoke chamber) kuenzanisa kudzikiswa kweSmoke Density Rating (SDR).
• Zvivakwa zveMichina: Ita shuwa kuti simba rekusimba uye simba rekunamatira zvinosangana nezvinodiwa mushure mekupora.
• Kugadziriswa: Simbisa kupararira kwakafanana kwezvinodzivisa moto pasina kukanganisa kusimba kana nguva yekupora.

5. Zvaunofanira Kufunga Nezve

• Kudzora Saizi yeZvidimbu: Sarudza zinc borate yakakura se nano-size (semuenzaniso, saizi yezvikamu <1 μm) kuti uwedzere kupararira kwayo.
• Kugadziriswa Kwepamusoro: Isa zinc borate ne silane coupling agent kuti ishande zvakanaka ne epoxy resin.
• Kutevedzera Mutemo: Ita shuwa kuti zvinhu zvinodzora moto zvakasarudzwa zvinoenderana neRoHS, REACH, nemimwe mitemo.

6. Muenzaniso weKugadzira (Reference)

7. Pfupiso

• Zinc borate isarudzo inoshanda yekuderedza kuburitswa kweutsi. Zvinokurudzirwa kuwedzera.10-15 phrukuwo zvichideredza zvine mwero huwandu hwealuminium hypophosphite/MCA.
• Kuti utsi hurambe huchidzikira, sanganisa nemakemikari emolybdenum (semuenzaniso,4-6 maprendi).
• Kuongororwa kwekuyedza kunodiwa kuti kuenzane nekusashanda kwemoto, kudzima utsi, uye hunhu hwemakanika.
