Ngokuthuthuka okuqhubekayo kwe-silicone, i-methyl cellulose ne-fluororubber, imakethe ye-chloromethane iyaqhubeka nokwenza ngcono Ukubuka konke Komkhiqizo I-Methyl Chloride, eyaziwa nangokuthi i-chloromethane, iyinhlanganisela ye-organic enefomula yamakhemikhali i-CH3Cl. Igesi engenambala ekamelweni lokushisa kanye nokucindezela...Funda kabanzi -
Amagesi we-laser excimer
I-Excimer laser iwuhlobo lwe-ultraviolet laser, evame ukusetshenziswa emikhakheni eminingi njengokukhiqiza ama-chip, ukuhlinzwa kwamehlo kanye nokucutshungulwa kwe-laser. I-Chengdu Taiyu Gas ingakwazi ukulawula ngokunembile isilinganiso ukuze ihlangabezane namazinga okuvusa amadlingozi we-laser, futhi imikhiqizo yenkampani yethu isetshenziswe ku...Funda kabanzi -
Kwembula isimangaliso sesayensi se-hydrogen ne-helium
Ngaphandle kobuchwepheshe be-hydrogen ewuketshezi kanye ne-helium ewuketshezi, ezinye izinsiza zesayensi ezinkulu zingaba yinqwaba yezinsimbi ezilahliwe… Kubaluleke kangakanani i-hydrogen ne-helium ewuketshezi? Ososayensi baseShayina bayinqoba kanjani i-hydrogen ne-helium okungenakwenzeka ukuncibilika? Ngisho nesikhundla phakathi kwabaphambili...Funda kabanzi -
Igesi ekhethekile ye-elekthronikhi esetshenziswa kakhulu - i-nitrogen trifluoride
Amagesi kagesi akhethekile ane-fluorine ahlanganisa i-sulfur hexafluoride (SF6), i-tungsten hexafluoride (WF6), i-carbon tetrafluoride (CF4), i-trifluoromethane (CHF3), i-nitrogen trifluoride (NF3), i-hexafluoroethane (C2F6) ne-octafluoropropane (C3F8). Ngokuthuthuka kwe-nanotechnology kanye ne...Funda kabanzi -
Izimpawu kanye nokusetshenziswa kwe-ethylene
Ifomula yamakhemikhali ithi C2H4. Iwumthombo wamakhemikhali ayisisekelo wemicu yokwenziwa, irabha yokwenziwa, amapulasitiki okwenziwa (i-polyethylene ne-polyvinyl chloride), kanye ne-ethanol yokwenziwa (utshwala). Ibuye isetshenziselwe ukwenza i-vinyl chloride, i-styrene, i-ethylene oxide, i-acetic acid, i-acetaldehyde, ne-expl ...Funda kabanzi -
I-Krypton iwusizo kakhulu
I-Krypton iyigesi engenambala, engenaphunga, enganambitheki, esinda ngokuphindwe kabili kunomoya. Ayisebenzi kakhulu futhi ayikwazi ukushisa noma ukusekela ukuvutha. Okuqukethwe kwe-krypton emoyeni kuncane kakhulu, kuno-1.14 ml kuphela we-krypton kuwo wonke umoya ongu-1m3. Ukusetshenziswa kwemboni ye-krypton Krypton kunomsebenzi obalulekile...Funda kabanzi -
High-purity xenon: okunzima ukuyikhiqiza futhi ayinakushintshwa
I-High-purity xenon, igesi ye-inert enobumsulwa obudlula u-99.999%, idlala indima ebalulekile ekucabangeni kwezokwelapha, ukukhanya okuphezulu, ukugcinwa kwamandla kanye nezinye izinkambu ezinombala futhi ezingenaphunga, ukuminyana okuphezulu, indawo ephansi yokubilisa kanye nezinye izakhiwo. Njengamanje, imakethe yomhlaba wonke ye-xenon ephezulu ...Funda kabanzi -
Yini i-silane?
I-Silane iyinhlanganisela ye-silicon ne-hydrogen, futhi iyitemu evamile yochungechunge lwezinhlanganisela. I-Silane ikakhulukazi ihlanganisa i-monosilane (SiH4), i-disilane (Si2H6) nezinye izinhlanganisela ze-silicon hydrogen ezisezingeni eliphezulu, ezinefomula evamile i-SinH2n+2. Kodwa-ke, ekukhiqizeni kwangempela, ngokuvamile sibhekisela kuma-monos...Funda kabanzi -
Igesi ejwayelekile: isisekelo sesayensi nezimboni
Emhlabeni omkhulu wocwaningo lwesayensi nokukhiqizwa kwezimboni, igesi evamile ifana neqhawe elithule ngemuva kwezigcawu, elidlala indima ebalulekile. Ayinayo nje inhlobonhlobo yezinhlelo zokusebenza, kodwa futhi ikhombisa ithemba lemboni elithembisayo. I-Standard gas iyingxube yegesi ene-concen eyaziwa ngokunembile...Funda kabanzi -
Ngaphambilini yayisetshenziselwa ukuqhumisa amabhaluni, i-helium manje isingesinye sezinsiza eziyivelakancane emhlabeni. Iyini ukusetshenziswa kwe-helium?
I-Helium ingelinye lamagesi ambalwa alula kunomoya. Okubaluleke nakakhulu, izinzile, ayinambala, ayinaphunga futhi ayinabungozi, ngakho-ke kuyisinqumo esihle kakhulu ukuyisebenzisela ukuqhumisa amabhaluni azihambelayo. Manje i-helium ivame ukubizwa ngokuthi "igesi engavamile yomhlaba" noma "igesi legolide". I-Helium ...Funda kabanzi
