Mhinduro dzinodzora moto dze thermoplastic elastomer TPE
Paunenge uchishandisa aluminium hypophosphite (AHP) uye melamine cyanurate (MCA) mu thermoplastic elastomers (TPE) kuti uwane chiyero cheUL94 V0 chinodzivirira moto, zvakakosha kufunga nezve mashandiro ekudzivirira moto, kuenderana kwezvinhu, uye mamiriro ekugadzirisa. Pazasi pane fomura inokurudzirwa:
1. Kurodha Kwakajairika Kana Kushandiswa Kwega Kwega
Aluminium Hypophosphite (AHP)
- Kurodha: 15-25%
- Hunhu: Inokurudzira kugadzirwa kwechar, yakakodzera masisitimu anoda mashandiro epamusoro emakanika, asi tembiricha yekugadzirisa inofanira kudzorwa (inokurudzirwa ≤240°C).
Melamine Cyanurate (MCA)
- Kurodha: 25-35%
- Hunhu: Inoenderana nekuora kwe endothermic uye kuderedzwa kwegasi; mutoro wakawanda unogona kuderedza kuchinjika kwezvinhu.
2. Fomura Inokurudzirwa Yekubatanidza Yakabatana
Chiyero chekubatanidza cheAHP neMCA
- AHP: 10-15%
- MCA: 10-20%
- Kutakura kwese: 20-30%
Zvakanakira: Simba rekubatana rinoderedza mutoro wese ukuwo richideredza kukanganiswa kwezvinhu zvemakanika (semuenzaniso, simba rekudhonza, kusimba kwesimba).
3. Zvinhu Zvikuru Zvinopesvedzera
- Rudzi rwezvinhu zvepakutanga: MaTPE akavakirwa paSEBS anowanzo kuve nyore kudzima moto kupfuura akavakirwa paSBS, zvichibvumira kuti mutoro wekuwedzera uve wakaderera zvishoma.
- Kukora kwemuenzaniso: Kutevedzera UL94 V0 kunoenderana nehukobvu (1.6mm inonetsa kupfuura 3.2mm), saka mafomura anofanirwa kugadziriswa zvinoenderana.
- Vatsigiri vekubatana: Kuwedzera 2-5% nano-clay kana talc kunogona kuwedzera kuumbwa kwechar uye kuderedza mutoro unodzivirira moto.
- Kugadzira Tembiricha: Ita shuwa kuti tembiricha dzekugadzirisa dzinoramba dziri pasi penzvimbo dzekuora dzeAHP (≤240°C) neMCA (≤300°C).
4. Matanho Ekusimbisa Anokurudzirwa
- Kuedzwa Kwekutanga: Itai miedzo midiki neAHP 12% + MCA 15% (27%).
- Kuedzwa Kwekushanda: Ongorora kunonoka kwemurazvo (UL94 vertical burning), kuomarara (Shore A), simba rekudhonza, uye chiyero chekuyerera kwekunyunguduka.
- Kugadzirisa: Kana mvura ikadonha, wedzerai chiyero cheAHP (kuti muwedzere kupisa); kana michina isina kunaka, fungai nezvekuwedzera mapurasitiki kana kuderedza mutoro wese.
5. Kungwarira
- Dzivisa kusanganisa nezvinozadza zvine acidic (semuenzaniso, zvimwe zvinodhayagira), sezvo zvinogona kukanganisa AHP.
- Kana TPE iine huwandu hwakawanda hwemapurasitiki akavakirwa pamafuta, mutoro unodzivirira moto ungada kuwedzerwa (mafuta anogona kuderedza kushanda zvakanaka kwekudzivisa moto).
Kuburikidza nekusanganisa zvine musoro uye kugadzirisa kuyedza, kutevedzera UL94 V0 kunogona kuwanikwa uku uchienzanisa kugona kweTPE uye mashandiro emakanika. Kushanda pamwe chete nevatengesi vezvinodzivirira moto kuti vawane mhinduro dzakagadzirwa zvinokurudzirwa.
