baaruud daahir sare leh

Maanta, waxaan ka wada hadli doonaa baaruud nadiif ah oo sarreeya.
Sulfur waa shay caadi ah oo leh codsiyo kala duwan. Waxaa laga helaa baaruudda (mid ka mid ah "Four Great Inventions"), oo loo isticmaalo daawaynta dhaqameed ee Shiinaha sifooyinkeeda lidka ku ah jeermiska, waxaana laga shaqeeyaa vulcanization caag ah si kor loogu qaado waxqabadka alaabta. Baaruud daahir-sare ah, si kastaba ha ahaatee, waxay leedahay codsiyo ka sii ballaadhan:
Codsiyada Muhiimka ah ee Sulfur-Nadiifinta Sare
1. Warshadaha Elektarooniga ah
o Qalabka Semiconductor: Waxaa loo isticmaalaa in lagu diyaariyo semiconductors sulfide (tusaale, cadmium sulfide, zinc sulfide) ama sida dopant si loo hagaajiyo sifooyinka alaabta.
o Batariyada Lithium: Baaruud daahir-sare ah waa qayb muhiim ah oo ka mid ah baytariyada lithium-sulfur cathodes; Nadiifkeedu wuxuu si toos ah u saameeya cufnaanta tamarta iyo nolosha meertada.
2. Kiimikada Synthesis
o Soo saarista sulfuric acid, sulfur dioxide, iyo kiimikooyin kale oo saafi ah oo sarreeya, ama il baaruud ah oo ku jira isku-dhafka organic (tusaale, dhexdhexaadiyeyaasha dawooyinka).
3. Qalabka indhaha
o Samaynta muraayadaha infrared iyo alaabta daaqadaha (tusaale, muraayadaha chalcogenide) oo ay ugu wacan tahay gudbinta sare ee kala duwanaanshaha hirarka dhererka gaarka ah.
4. Daawooyinka
o Walxaha ceeriin ee daroogooyinka (tusaale, boomaatada sulfur) ama sideyaasha calaamadaynta radioisotope.
5. Cilmi-baadhis cilmiyeed
o Isku-dubbaridka agabka-conducting-ka sare, dhibcaha quantum-ka, ama qaybaha nano-sulfur, oo u baahan nadiifnimo aad u sarreeya.

Hababka Nadiifinta Sare ee Sulfurka ee Sichuan Jingding Technology
Shirkaddu waxay soo saartaa 6N (99.9999%) baaruud nadiif ah oo heer elektaroonik ah iyadoo la adeegsanayo farsamooyinka soo socda:
1. Distillation
o Mabda'a: Kala sooca baaruudka (barta karkarinta: 444.6°C) wasakhda iyada oo loo marayo vacuum ama nadiifinta jawiga.
o Faa'iidooyinka: wax soo saarka heerka warshadaha.
o Qasaarooyinku: Waxa laga yaabaa inay hayso wasakhda leh dhibco isku mid ah oo karkaraya.
2. Sifaynta Aagga
o Mabda'a: Wuxuu dhaqaajiyaa aag dhalaalaysa si uu uga faa'iidaysto kala soocidda wasakhda ee u dhaxaysa wejiyada adag iyo dareeraha.
o Faa'iidooyinka: Wuxuu gaadhaa daahirin aad u sarreeya (>99.999%).
o Qasaarooyinka: Waxtarka hooseeya, qiimaha sare; ku haboon shaybaadhka ama wax soo saarka yar yar.
3. Kaydinta Uumiga Kiimikada (CVD)
o Mabda'a: Wuxuu qurxiyaa sulfide gaseous (tusaale, H₂S) si uu ugu shubo baaruud saafi ah oo sarreeya substrates.
o Faa'iidooyinka: Ku habboon walxaha filimada khafiifka ah ee nadiifka ah.
o Qasaarooyinka: Qalab isku dhafan.
4. Crystallization Solvent
o Mabda'a: Dib-u-crystallizes sulfur iyadoo la isticmaalayo dareerayaasha (tusaale, CS₂, toluene) si ay wasakhda uga saarto.
o Faa'iidooyinka: Wax ku ool u ah wasakhda dabiiciga ah.
o Qasaarooyinka: Waxay u baahan tahay maaraynta dareerayaasha sunta ah.

Hagaajinta Habka Elektrooniga/Fasalka indhaha (99.9999%)
Isku darka sida sifaynta aagga + CVD ama CVD + dareeraha dareeraha ayaa la shaqeeyaa. Istaraatiijiyadda sifaynta waxaa lagu habeeyey noocyada wasakhda iyo shuruudaha nadiifnimada, iyadoo la hubinayo hufnaanta iyo saxnaanta.
habka ayaa tusaale u ah sida hababka isku-dhafan ay ugu suurtageliyaan nadiifinta dabacsanaanta, waxqabadka sare ee codsiyada cirifka leh ee elektiroonigga, kaydinta tamarta, iyo agabka horumarsan.
