Izixazululo ezivimbela ilangabi ze-thermoplastic elastomer TPE

Izixazululo ezivimbela ilangabi ze-thermoplastic elastomer TPE

Uma usebenzisa i-aluminium hypophosphite (AHP) kanye ne-melamine cyanurate (MCA) kuma-elastomers e-thermoplastic (TPE) ukuze kufinyelelwe isilinganiso se-UL94 V0 sokuvimbela umlilo, kubalulekile ukucabangela indlela yokuvimbela umlilo, ukuhambisana kwezinto, kanye nezimo zokucubungula. Ngezansi ifomula enconywayo:

1. Ukulayisha Okuvamile Uma Kusetshenziswa Ngayinye

I-Aluminium Hypophosphite (AHP)

• Ukulayisha: 15-25%
• Izici: Ikhuthaza ukwakheka kwe-char, ifanele izinhlelo ezidinga ukusebenza okuphezulu kwemishini, kodwa izinga lokushisa lokucubungula kufanele lilawulwe (kunconywa ≤240°C).

I-Melamine Cyanurate (MCA)

• Ukulayisha: 25-35%
• Izici: Ithembele ekuqhekekeni kwe-endothermic kanye nokuncibilikiswa kwegesi; umthwalo omningi unganciphisa ukuguquguquka kwezinto.

2. Ifomula Yokuxuba Ehlanganisiwe Enconyiwe

Isilinganiso Sokuxuba se-AHP ne-MCA

• I-AHP: 10-15%
• I-MCA: 10-20%
• Inani lokulayisha: 20-30%

Izinzuzo: Umphumela wokubambisana unciphisa umthwalo ophelele ngenkathi unciphisa umthelela ezimpahleni zemishini (isb., amandla okudonsa, ukuguquguquka).

3. Izinto Ezibalulekile Ezithonyayo

• Uhlobo Lwezinto Eziyisisekelo: Ama-TPE asekelwe ku-SEBS ngokuvamile kulula ukuwavimba ngomlilo kunalawo asekelwe ku-SBS, okuvumela ukulayisha okungeziwe okuphansi kancane.
• Ubukhulu besampula: Ukuhambisana kwe-UL94 V0 kuyazwela ekujiyeni (i-1.6mm inzima kakhulu kune-3.2mm), ngakho-ke ukwakheka kumele kulungiswe ngokufanele.
• Ama-Synergists: Ukwengeza u-2-5% we-nano-clay noma i-talc kungathuthukisa ukwakheka kwe-char futhi kunciphise umthwalo ovimbela ilangabi.
• Icubungula Izinga Lokushisa: Qinisekisa ukuthi amazinga okushisa okucubungula ahlala ngaphansi kwamaphuzu okubola e-AHP (≤240°C) kanye ne-MCA (≤300°C).

4. Izinyathelo Zokuqinisekisa Ezinconyiwe

• Ukuhlolwa Kwangaphambi Kokuqala: Yenza izivivinyo ezincane nge-AHP 12% + MCA 15% (inani eliphelele elingu-27%).
• Ukuhlolwa Kokusebenza: Hlola ukuncipha komlilo (ukusha okuqondile kwe-UL94), ubulukhuni (i-Shore A), amandla okudonsa, kanye nenkomba yokugeleza kokuncibilika.
• UkuthuthukisaUma kuvela ukuconsa, yandisa isilinganiso se-AHP (ukuthuthukisa ukusha); uma izakhiwo zemishini zimbi, cabanga ngokufaka ama-plasticizer noma ukunciphisa umthwalo ophelele.

5. Izinyathelo Zokuqapha

• Gwema ukuhlanganisa nama-filler ane-asidi (isib., ama-colorant athile), ngoba angase aphazamise i-AHP.
• Uma i-TPE iqukethe inani elikhulu lama-plasticizer asekelwe ku-oyela, umthwalo ovimbela ilangabi ungadinga ukwanda (uwoyela unganciphisa ukusebenza kahle kokuvimbela ilangabi).

Ngokuhlanganisa okunengqondo kanye nokwenza ngcono kokuhlola, ukuhambisana kwe-UL94 V0 kungafinyelelwa ngenkathi kulinganiswa ukucutshungulwa kwe-TPE kanye nokusebenza komshini. Kunconywa ukusebenzisana nabahlinzeki be-flame retardant ukuthola izixazululo ezenziwe ngokwezifiso.
