Amfani da HTPB a cikin Tukwane/rufe Kayan Lantarki
HTPB (Polybutadiene da aka dakatar da Hydroxyl), a matsayin elastomer mai aiki mai kyau, yana ba da fa'idodi na musamman a aikace-aikacen tukunya don kayan lantarki, musamman a cikin yanayi da ke buƙatar sassauci, juriya ga yanayi, da rufin lantarki. Ga taƙaitaccen bayani game da mahimman bayanai game da amfani da HTPB don tukunyar lantarki:
**1. Halaye da Amfanin HTPB ga Tukunya**
1. - Sassauci da Juriyar Tasiri: Bayan warkarwa, HTPB yana samar da elastomer wanda ke shan matsin lamba na injiniya, yana kare abubuwan lantarki masu mahimmanci (misali, na'urori masu auna firikwensin, allon da'ira) daga girgiza ko faɗaɗa zafi.
2. - Rufe Wutar Lantarki: Juriyar girma mai yawa (>10¹⁴ Ω·cm), wanda hakan ya sa ya dace da rufin wutar lantarki mai ƙarfi ko watsa sigina mai yawan mita.
3.- Juriyar Sinadarai da Yanayi: Yana jurewa acid, alkalis, da hasken UV, wanda ya dace da na'urorin lantarki na waje (misali, akwatunan mahaɗar PV, na'urorin lantarki na mota).
4.- Ragewar Warkewa: Yana rage damuwa ta ciki bayan an yi amfani da tukunya, yana hana lalacewar sassan ko tsagewa.
5.- Juriyar Danshi da Kura: Yana ba da kariya mai inganci daga gurɓatattun muhalli.
**2. Tsarin Kayan Tukunya**
- Zaɓin Tsarin Gyara:
- Isocyanates (misali, TDI, IPDI): Yana samar da hanyoyin sadarwa na polyurethane; rabon NCO/OH (yawanci 1.05–1.1:1) dole ne a sarrafa shi don daidaita tauri da sassauci.
- Maganin Peroxide: Ya dace da amfani da zafi mai yawa amma yana iya rage sassauci.
- Ƙarin Cika:
- Cikakkun abubuwan da ke haifar da zafi: Boron nitride (mai hana ruwa shiga da kuma mai hana zafi shiga), alumina (mai tasiri ga farashi).
- Masu hana harshen wuta: Aluminum hydroxide, masu hana harshen wuta bisa phosphorus don cika ka'idojin UL94 V-0.
- Masu yin robobi: misali, DOA (Dioctyl Adipate) don ƙara rage modulus, kodayake dole ne a tantance haɗarin ƙaura.
**3. Aikace-aikacen da aka saba**
- Kayan Lantarki na Soja/Aerospace: Tukwane don da'irori masu linzami, abubuwan radar, da amfani da su HTPBYanayin zafin jiki mai faɗi (-50°C zuwa 80°C).
- Sabon Sashen Makamashi: Fakitin batirin lithium, kariyar tsarin caji, daidaita rufi da kuma shan girgiza.
- Kayan Aikin Ƙarƙashin Ruwa: Tukunyar haɗin kebul na ƙarƙashin ruwa, mai jure wa tsatsa da kuma hana ruwa shiga.
- Allunan da'ira da aka buga (PCBs)
- Sadarwa da Kayayyakin Sadarwa
- Makamashi Mai Sabuntawa da Lantarki Mai Lantarki
- Lantarkin Ruwa
- Kayan Lantarki Masu Amfani Masu Inganci Mai Dorewa
**4. La'akari da Tsarin Aiki**
- Cire Kumfa: Rufe iskar gas (-0.095 MPa, mintuna 10-20) don hana iska shiga bayan ta bushe.
- Yanayin Warkewa: Warkewa da zafin ɗaki (awanni 24-48); dumama (60-80°C) yana rage lokacin warkewa zuwa awanni 4-8.
- Mannewa Kafin A Yi: Ana buƙatar maganin plasma ko firam don abubuwan da ba su da polar (misali, PE) don haɓaka haɗin kai.
**5. Kwatanta da Sauran Kayan Tukunya**
| Kadara | Guduron Epoxy | Rufin Silicone | |
| sassauci | Mai kyau (> 200% tsawo) | Matalauta (mai rauni) | Mafi kyau (>300%) |
| Juriyar Zafi Mai Girma | Matsakaici (100°C) | Mafi kyau (150–200°C) | Mafi kyau (200–250°C) |
| farashi | Matsakaici | Ƙasa | Babban |
| Wahalar Tsarin Aiki | Matsakaici (sarrafa danshi) | Ƙasa | Matsakaici (mai kara kuzari na platinum) |
**6. Dabaru na Ingantawa**
- Gyaran Nano: Haɗa nano-SiO₂ don haɓaka ƙarfin injina (misali, ƙarfin tauri yana ƙaruwa daga 5 MPa zuwa 8 MPa).
- Tsarin Haɗawa: Haɗakarwa tare da epoxy (misali, EP/HTPB hanyoyin sadarwa masu shiga tsakani) don daidaita tauri da tauri.
HTPB Kayan tukunya sun dace musamman don kariyar lantarki a cikin yanayi mai ƙarfi, kuma ya kamata a inganta tsarin da aka yi amfani da shi bisa ga takamaiman buƙatun aiki.
Kamfaninmu yana bayarwa HTPB a cikin matakai daban-daban kuma yana ba da samarwa na musamman bisa ga ƙayyadaddun buƙatun abokin ciniki.
