Ukusetshenziswa kwe-HTPB ekubumbeni/ekuhlanganiseni izinto ze-elekthronikhi
I-HTPB (i-Hydroxyl-Terminated Polybutadiene), njenge-elastomer esebenza kahle kakhulu, inikeza izinzuzo ezihlukile ekusetshenzisweni kwe-potting yezinto zikagesi, ikakhulukazi ezimweni ezidinga ukuguquguquka, ukumelana nesimo sezulu, kanye nokufakwa kokushisa kagesi. Ngezansi kunesifinyezo samaphuzu abalulekile mayelana nokusetshenziswa kwe- I-HTTPB ngokubhaka izimbiza ngogesi:
**1. Izici kanye nezinzuzo ze-HTPB zokufaka imbiza**
1. - Ukuguquguquka kanye nokumelana nomthelela: Lapho iqina, I-HTTPB Yakha i-elastomer emunca ukucindezeleka komshini, ivikele izingxenye ze-elekthronikhi ezizwelayo (isb., izinzwa, amabhodi wesekethe) ekudlidlizeni noma ekukhuleni kokushisa.
2. -Ukufakwa Kogesi: Ukumelana nomthamo ophezulu (>10¹⁴ Ω·cm), okwenza kufaneleke ukufakelwa kogesi okunamandla aphezulu noma ukudluliselwa kwesignali okunamandla aphezulu.
3.- Ukumelana Kwamakhemikhali Nesimo Sezulu: Kumelana nama-acid, ama-alkali, kanye nemisebe ye-UV, kulungele amadivayisi kagesi angaphandle (isb., amabhokisi e-PV junction, ama-electronic ezimoto).
4.- Ukuncipha Okuphansi Kokuphulukisa: Kunciphisa ukucindezeleka kwangaphakathi ngemva kokubhoboza, kuvimbele ukuguquka noma ukuqhekeka kwezingxenye.
5.- Ukumelana Nomswakama Nothuli: Kuhlinzeka ngesivikelo esisebenzayo ekungcoleni kwemvelo.
**2. Umklamo Wokwakhiwa Kwezinto Zokubumba**
- Ukukhetha Uhlelo Lokwelapha:
- Ama-Isocyanates (isb., i-TDI, i-IPDI): Akha amanethiwekhi e-polyurethane; isilinganiso se-NCO/OH (ngokuvamile esingu-1.05–1.1:1) kumele silawulwe ukuze kulinganiswe ubulukhuni kanye nokunwebeka.
- Ukwelapha i-Peroxide: Kufanelekela ukusetshenziswa kwezinga lokushisa eliphezulu kodwa kunganciphisa ukuguquguquka.
- Izithasiselo Zokugcwalisa:
- Ama-Filler Okulawula Ukushisa: i-Boron nitride (evikela futhi eqhuba ukushisa), i-alumina (engabizi kakhulu).
- Izinto Ezivimbela Amalangabi: I-aluminium hydroxide, izinto ezivimbela amalangabi ezisekelwe ku-phosphorus ukuze zihlangabezane nezindinganiso ze-UL94 V-0.
- Ama-plasticizer: isib., i-DOA (i-Dioctyl Adipate) ukuze kuncishiswe i-modulus, yize izingozi zokufuduka kumele zihlolwe.
**3. Izinhlelo Zokusebenza Ezijwayelekile**
- I-Electronics Yezempi/Yezindiza: Ukufaka izitsha zesekethe zemicibisholo, izingxenye ze-radar, ukusebenzisa I-HTTPBububanzi bokushisa (-50°C kuya ku-80°C).
- Umkhakha Omusha Wamandla: Ukufakwa kwe-lithium battery pack, ukuvikelwa kwemojula yokushaja, ukulinganisela ukuvikela kanye nokumuncwa kwe-shock.
- Imishini Engaphansi Kwamanzi: Ukufakwa kwembiza yekhebula lomkhumbi ongaphansi kwamanzi, okumelana nokugqwala kwamanzi anosawoti futhi ongangeni manzi.
- Amabhodi wesekethe aphrintiwe (ama-PCB)
- Ingqalasizinda Yezokuxhumana Nenethiwekhi
- Amandla Avuselelekayo kanye Ne-Elektroniki Yamandla
- Izinto zikagesi zasemanzini
- Ama-elekthronikhi Abathengi Ahlala Isikhathi Eside
**4. Izinto Okucatshangwayo Ngenqubo**
- Ukususwa Kwamabhamuza: Ukususa igesi nge-vacuum (-0.095 MPa, imizuzu eyi-10–20) ukuvimbela amaphakethe omoya ngemva kokuqina.
- Izimo Zokuphilisa: Ukuphilisa ngezinga lokushisa legumbi (amahora angu-24–48); ukufudumeza (60–80°C) kunciphisa isikhathi sokuphilisa sibe amahora angu-4–8.
- Ukunamathela Ngaphambi Kokwelashwa: Ukwelashwa nge-plasma noma ama-primer adingekayo kuma-substrate angewona ama-polar (isb., i-PE) ukuze kuthuthukiswe ukubopha.
**5. Ukuqhathaniswa Nezinye Izinto Zokubumba**
| Impahla | I-Epoxy Resin | Irabha ye-Silicone | |
| Ukunwebeka | Kuhle kakhulu (ukwelulwa okungu->200%) | Kubi (kubuthakathaka) | Kuhle kakhulu (>300%) |
| Ukumelana Nokushisa Okuphezulu | Okumaphakathi (100°C) | Kuhle kakhulu (150–200°C) | Kuhle kakhulu (200–250°C) |
| Izindleko | Okumaphakathi | Phansi | Phezulu |
| Ubunzima Benqubo | Okumaphakathi (ukulawula umswakama) | Phansi | Okumaphakathi (i-platinum catalyst) |
**6. Amasu Okuthuthukisa**
- Ukuguqulwa kwe-Nano: Ukufaka i-nano-SiO₂ ukuthuthukisa amandla omshini (isb., amandla okudonsa ayanda kusuka ku-5 MPa kuya ku-8 MPa).
- Izinhlelo Zokuhlanganisa: Ukuhlanganiswa kwe-polymer ne-epoxy (isb., I-EP/HTTPB amanethiwekhi angena ngaphakathi) ukuze kulinganiswe ukuqina nokuqina.
I-HTTPB Izinto zokufaka izimbiza zifanelekela kakhulu ukuvikelwa kwe-elekthronikhi ezindaweni eziguquguqukayo, futhi ukwakheka kufanele kwenziwe ngcono ngokusekelwe ezidingweni ezithile zokusebenza.
Inkampani yethu inikeza I-HTTPB emabangeni ahlukahlukene futhi inikeza ukukhiqizwa okwenziwe ngokwezifiso ngokusekelwe ezimisweni zamakhasimende ezidingekayo.
