Ukusetyenziswa kwe-HTPB ekufakeni/ekugqumeni izixhobo ze-elektroniki
I-HTPB (iHydroxyl-Terminated Polybutadiene), njenge-elastomer esebenza kakuhle, inika iingenelo ezikhethekileyo ekusetyenzisweni kweembiza kwizixhobo ze-elektroniki, ngakumbi kwiimeko ezifuna ukuguquguquka, ukumelana nemozulu, kunye nokufakelwa kombane. Apha ngezantsi kukho isishwankathelo seengongoma eziphambili malunga nokusetyenziswa kwe I-HTTPB ukulungiselela ukubhola nge-elektroniki:
**1. Iimpawu kunye neenzuzo ze-HTPB kwiPotting**
1. - Ukuguquguquka kunye nokumelana nempembelelo: Xa inyibilika, I-HTTPB Yenza i-elastomer efunxa uxinzelelo loomatshini, ikhusela izinto ze-elektroniki ezinobuthathaka (umz., ii-sensors, iibhodi zesekethe) ekungcangcazelweni okanye ekwandeni kobushushu.
2. -Ukufakwa kombane: Ukumelana nomthamo ophezulu (>10¹⁴ Ω·cm), okwenza ukuba ifaneleke ukufakelwa kombane ombane ophezulu okanye ukuhanjiswa kwesignali ombane ophezulu.
3.- Ukumelana neekhemikhali kunye nemozulu: Iyamelana nee-asidi, ii-alkalis, kunye nemitha ye-UV, ifanelekile kwizixhobo ze-elektroniki zangaphandle (umz., iibhokisi ze-PV junction, ii-elektroniki zeemoto).
4.- Ukuncitshiswa Okuncinci Kokunyanga: Kunciphisa uxinzelelo lwangaphakathi emva kokugalela, kuthintela ukuguquka okanye ukuqhekeka kwenxalenye.
5.- Ukumelana nokufuma nothuli: Ibonelela ngokhuseleko olusebenzayo kwizinto ezingcolisayo kwindalo.
**2. Uyilo lweMifuno yezinto zokubumba**
- Ukhetho lweNkqubo yokuPhilisa:
- Ii-Isocyanates (umz., i-TDI, i-IPDI): Zenza iinethiwekhi ze-polyurethane; umlinganiselo we-NCO/OH (ngesiqhelo yi-1.05–1.1:1) kufuneka ulawulwe ukuze kulinganiswe ubulukhuni kunye nokuthamba.
- Ukucoca iPeroxide: Ifanelekile ukusetyenziswa kumaqondo obushushu aphezulu kodwa inokunciphisa ukuguquguquka.
- Izongezo zokugcwalisa:
- Izizalisi zoQhuba ubushushu: iBoron nitride (ikhusela kwaye ihambisa ubushushu), i-alumina (ingabizi kakhulu).
- Izinto ezithintela ilangatye: Izinto ezithintela ilangatye ezisekelwe kwi-aluminium hydroxide, ezithintela ilangatye ezisekelwe kwi-phosphorus ukuhlangabezana nemigangatho ye-UL94 V-0.
- Iiplastiki: umz., i-DOA (i-Dioctyl Adipate) ukunciphisa ngakumbi i-modulus, nangona iingozi zokufuduka kufuneka zihlolwe.
**3. Ii-Applications eziqhelekileyo**
- Izixhobo ze-elektroniki zomkhosi/ze-Aerospace: Ukufaka iimbiza zeesekethe zee-missile, izixhobo ze-radar, ukusebenzisa I-HTTPBuluhlu olubanzi lobushushu (-50°C ukuya kuma-80°C).
- Icandelo Elitsha Lamandla: Ukufakwa kwe-lithium battery pack, ukukhuselwa kwe-charging module, ukulinganisela i-insulation kunye ne-shock absorption.
- Izixhobo ezisetyenziswa phantsi kwamanzi: Iimbiza ezidityaniswe ngentambo yolwandle, ezimelana nokugqwala kwamanzi anetyuwa kwaye ezingangeni manzi.
- Iibhodi zesekethe eziprintiweyo (ii-PCB)
- Iziseko zoNxibelelwano kunye neNethiwekhi
- Amandla aHlaziyiweyo kunye nee-Elektroniki zamandla
- Izixhobo zombane zaselwandle
- Izixhobo ze-elektroniki zabathengi ezihlala ixesha elide
**4. Izinto ekufuneka ziqwalaselwe kwinkqubo**
- Ukususwa kwamaqamza: Ukukhupha igesi nge-vacuum (-0.095 MPa, imizuzu eli-10–20) ukuthintela iipokotho zomoya emva kokuba zipholile.
- Iimeko Zokunyanga: Ukunyanga ubushushu begumbi (iiyure ezingama-24–48); ukufudumeza (60–80°C) kunciphisa ixesha lokunyanga ukuya kwiiyure ezi-4–8.
- Ukuncamathelisa Ngaphambi Konyango: Unyango lwePlasma okanye iiprimer ezifunekayo kwi-substrates ezingezizo ezo zi-polar (umz., i-PE) ukuphucula ukubopha.
**5. Uthelekiso nezinye izinto zokubhaka**
| Ipropati | I-Epoxy Resin | Irabha yeSilicone | |
| Ukuthamba | Igqwesile (ukwandiswa okungaphezulu kwama-200%) | Imbi (incinci) | Igqwesile (>300%) |
| Ukumelana nobushushu obuphezulu | Eliphakathi (100°C) | Igqwesile (150–200°C) | Igqwesile (200–250°C) |
| Ixabiso | Iphakathi | Iphantsi | Phezulu |
| Ubunzima beNkqubo | Eliphakathi (ulawulo lomswakama) | Iphantsi | I-Ephakathi (i-platinum catalyst) |
**6. Amaqhinga okuphucula**
- Ukuguqulwa kweNano: Ukufaka i-nano-SiO₂ ukuphucula amandla oomatshini (umz., amandla okutsalwa ayanda ukusuka kwi-5 MPa ukuya kwi-8 MPa).
- Iinkqubo zokudibanisa: Ukudibanisa i-polymer kunye ne-epoxy (umz., I-EP/HTTPB iinethiwekhi ezingenela ngaphakathi) ukulinganisela ukuqina nokuqina.
I-HTTPB Izinto zokubumba zilungele ngokukodwa ukhuseleko lwe-elektroniki kwiindawo eziguquguqukayo, kwaye iifomyula kufuneka zilungiselelwe ngokusekelwe kwiimfuno ezithile zokusebenza.
Inkampani yethu inikezela I-HTTPB kwiindidi ezahlukeneyo kwaye ibonelela ngemveliso eyenzelwe wena ngokusekelwe kwiinkcukacha zabathengi ezifunekayo.
