Ngenkathi amasistimu okugreda ensimbi awo womabili la mazwe ahlanganyela ukuxhumana, aphinde abonise umehluko ohlukile. ...Funda kabanzi -
Indlela yokubala inani lamapayipi ensimbi ku-hexagonal bundle?
Lapho izigayo zensimbi zikhiqiza iqoqo lamapayipi ensimbi, ziyawahlanganisa abe ama-hexagonal ukuze kube lula ukuhamba nokubala. Inqwaba inamapayipi ayisithupha ohlangothini ngalunye. Mangaki amapayipi kunqwaba ngayinye? Impendulo: 3n(n-1)+1, lapho u-n eyinombolo yamapayipi ohlangothini olulodwa lokuphuma...Funda kabanzi -
Uyini ngempela umehluko phakathi kwe-zinc-flower galvanizing kanye ne-zinc-free galvanizing?
Izimbali ze-Zinc zimelela isici se-surface morphology yekhoyili ecwebile ehlanganiswe nezinc. Lapho umucu wensimbi udlula ebhodweni le-zinc, ubuso balo bumbozwa nge-zinc encibilikisiwe. Ngesikhathi sokuqina kwemvelo kwalolu ungqimba lwe-zinc, i-nucleation kanye nokukhula kwekristalu ye-zinc ...Funda kabanzi -
Indlela yokuhlukanisa i-hot-dip galvanizing kusuka ku-electrogalvanizing?
Yiziphi izigqoko ze-hot-dip ezijwayelekile? Kunezinhlobo eziningi ze-hot-dip coatings zamapuleti ensimbi nemicu. Imithetho yokuhlukanisa phakathi kwamazinga amakhulu—okuhlanganisa namazinga kazwelonke aseMelika, aseJapane, aseYurophu, nawaseShayina—iyafana. Sizohlaziya sisebenzisa...Funda kabanzi -
Uyini umehluko phakathi kwensimbi ye-C-channel nensimbi yesiteshi?
Umehluko obonakalayo (umehluko ekubunjweni kwe-cross-sectional): Insimbi yesiteshi ikhiqizwa ngokuginqika okushisayo, ekhiqizwa ngokuqondile njengomkhiqizo oqediwe yizigayo zensimbi.

Uyini umehluko phakathi kwamapuleti aphakathi nendawo nasindayo namapuleti ayisicaba?
Ukuxhumana phakathi kwamapuleti aphakathi nendawo nasindayo kanye nama-slabs avulekile ukuthi zombili ziyizinhlobo zamapuleti ensimbi futhi zingasetshenziswa emikhakheni ehlukahlukene yokukhiqiza nezimboni zokukhiqiza. Ngakho, uyini umehluko? I-slab evulekile: Ipuleti eliyisicaba elitholakala ngokuqaqa amakhoyili ensimbi, ...Funda kabanzi -
Uyini umehluko phakathi kwe-SECC ne-SGCC?
I-SECC ibhekisela eshidini lensimbi elakhiwe nge-electrolytically galvanized. Isijobelelo esithi “CC” ku-SECC, njenge-SPCC yezinto eziyisisekelo (ishidi lensimbi eligoqiwe elibandayo) ngaphambi kwe-electroplating, sibonisa ukuthi into esetshenziswayo evamile egoqwe ngokubanda. Ibonisa ukusebenza okuhle kakhulu. Ngaphezu kwalokho, ngenxa...Funda kabanzi -
