Igisubizo cya sisitemu yo kugabanya ubukana bwa firime ya TPU

Igisubizo kiboneye cyo kugabanya ubukana bwa firime ya TPU (Ibiriho: 280; Intego: <200)
(Imiterere yubu: Aluminium hypophosphite interuro 15, MCA 5 interuro, Zinc borate 2 interuro)

I. Isesengura ry'ibibazo

1. Imipaka yuburyo bugezweho:

• Aluminium hypophosphite: Byibanze guhagarika ikirimi cyakwirakwijwe ariko gifite umwotsi muke.
• MCA.
• Zinc borate: Itezimbere gushiraho char ariko irakoreshwa (interuro 2 gusa), kunanirwa gukora char yuzuye yuzuye kugirango ihagarike umwotsi.

1. Ibisabwa by'ingenzi:

• Kugabanya ubukana bwumwotsi ukoreshejechar-yongerewe imbaraga zo guhagarika umwotsicyangwauburyo bwa gazi yo kugabanya.

II. Ingamba zo Gukwirakwiza

1. Guhindura ibipimo biriho

• Aluminium hypophosphite: Ongera kuri18–20 interuro.
• MCA: Ongera kuri6-8 interuro(byongera ibikorwa bya gaz-icyiciro; amafaranga menshi arashobora gutesha agaciro gutunganya).
• Zinc borate: Ongera kuri3-4 interuro(ishimangira gushiraho char).

Urugero rwahinduwe:

• Aluminium hypophosphite: 18 interuro
• MCA: 7 interuro
• Zinc borate: interuro 4

2. Kumenyekanisha ibintu byinshi byangiza umwotsi

• Molybdenum(urugero, zinc molybdate cyangwa amonium molybdate):
• Uruhare: Catalize char char, ikora inzitizi yuzuye yo guhagarika umwotsi.
• Umubare: 2-3 interuro (ihuza na zinc borate).
• Nanoclay (montmorillonite):
• Uruhare: Inzitizi yumubiri kugirango igabanye imyuka yaka.
• Umubare: 3-5 interuro (hejuru-yahinduwe kugirango itatanye).
• Silicone ishingiye kumuriro:
• Uruhare: Kunoza ubwiza bwa char no guhagarika umwotsi.
• Umubare: 1-2 interuro (irinda gutakaza umucyo).

3. Gukoresha sisitemu yo guhuza ibikorwa

• Zinc borate: Ongeramo interuro 1-2 kugirango uhuze na aluminium hypophosphite na zinc borate.
• Amonium polyphosifate (APP): Ongeraho interuro 1-2 kugirango uzamure ibikorwa bya gaz-icyiciro hamwe na MCA.

III. Basabwe Gutegura Byuzuye

Ibisubizo Biteganijwe:

• Umwotsi mwinshi: ≤200 (ukoresheje char + gazi-icyiciro cya synergie).
• Nyuma yubucucike bwumwotsi: Komeza ≤200 (MCA + zinc borate).

IV. Ingingo z'ingenzi zo Kuzamura Inyandiko

1. Gutunganya Ubushyuhe: Komeza 180–200 ° C kugirango wirinde kwangirika kwumuriro utaragera.
2. Gutatana:

• Koresha umuvuduko mwinshi wo kuvanga (≥2000 rpm) kugirango ukwirakwize nanoclay / molybdate.
• Ongeramo 0.5-1 interuro ihuza silane (urugero, KH550) kugirango utezimbere kuzuza.

1. Imiterere ya firime: Kubitera, gabanya igipimo cyo gukonjesha kugirango byorohereze char layer.

V. Intambwe zo Kwemeza

1. Kwipimisha Laboratoire: Tegura ingero kuri formulaire isabwa; kora ibizamini bya UL94 bihagaritse kandi byuzuye umwotsi (ASTM E662).
2. Impirimbanyi: Gerageza imbaraga zingana, kurambura, no gukorera mu mucyo.
3. Gukwirakwiza Iterative: Niba umwotsi ukomeje kuba mwinshi, uhindure buhoro buhoro molybdate cyangwa nanoclay (ph 1 interuro).

VI. Igiciro & Ibishoboka

• Ingaruka y'Ibiciro: Zinc molybdate (~ ¥ 50 / kg) + nanoclay (~ ¥ 30 / kg) yongerera igiciro cyose <15% kuri ≤10% yikuramo.
• Ingano yinganda: Bihujwe no gutunganya TPU isanzwe; nta bikoresho kabuhariwe bikenewe.

VII. Umwanzuro

Nakongera zinc borate + wongeyeho molybdate + nanoclay, sisitemu-ibikorwa-bitatugushiraho char + gusohora gazi + inzitizi yumubiri) irashobora kugera ku ntego yo gutwika umwotsi (≤200). Shyira imbere kugeragezamolybdate + nanoclayguhuza, hanyuma uhuze neza igipimo cyibiciro-imikorere iringaniye.
