1, Ukubuka konke kwemboni yesakhiwo sensimbi

Isakhiwo sensimbi siyisakhiwo esakhiwe ngezinto zensimbi, okungenye yezinhlobo eziyinhloko zezakhiwo zokwakha. Isakhiwo sakhiwe kakhulu ngemishayo yensimbi, izinsika zensimbi, izisekelo zensimbi nezinye izingxenye ezenziwe ngensimbi yesigaba kanye namapuleti ensimbi, futhi samukela i-silane, i-phosphating ye-manganese emsulwa, ukuwasha ngamanzi, ukomisa, ukugaya kanye nezinye izinqubo zokususa ukugqwala kanye nokuvimbela ukugqwala. Izithungo zokushisela, amabhawodi noma ama-rivets zivame ukusetshenziselwa ukuxhuma amalungu noma izingxenye. Ngenxa yesisindo saso esilula kanye nokwakhiwa okulula, sisetshenziswa kabanzi ezitshalweni ezinkulu, ezindaweni, ezinde kakhulu nakwamanye amasimu. Sinezici ezilandelayo: 1. Amandla aphezulu ezinto ezibonakalayo kanye nesisindo esilula; 2. Ukuqina kwensimbi, i-plasticity enhle, izinto ezifanayo, ukuthembeka okuphezulu kwesakhiwo; 3. Izinga eliphezulu lomshini ekukhiqizeni nasekufakeni isakhiwo sensimbi; 4. Ukusebenza kahle kokuvala kwesakhiwo sensimbi; 5. Isakhiwo sensimbi simelana nokushisa kodwa asimelani nomlilo; 6. Ukumelana nokugqwala okubi kwesakhiwo sensimbi; 7. Ikhabhoni ephansi, ukonga amandla, kuluhlaza futhi kungasetshenziswa kabusha.

2, isimo sokuthuthukiswa kwemboni yesakhiwo sensimbi

Eminyakeni yamuva nje, imboni yezakhiwo zensimbi yaseShayina ibhekane nenqubo kusukela ekuqaleni kancane kuya ekuthuthukisweni okusheshayo. Ngo-2016, umbuso ukhiphe imibhalo eminingi yenqubomgomo ukuxazulula inkinga yokusetshenziswa ngokweqile kwensimbi nokukhuthaza intuthuko eluhlaza neqhubekayo embonini yokwakha. Ngo-2019, uMnyango Wezindlu Nokuthuthukiswa Kwezindawo Zasemakhaya wakhipha "amaphuzu abalulekile omsebenzi ka-2019 womnyango wokuqondisa imakethe yokwakha woMnyango Wezindlu Nokuthuthukiswa Kwezindawo Zasemakhaya", owawudinga ukwenza umsebenzi wokuhlola wezindlu ezakhiwe ngaphambili zesakhiwo sensimbi; NgoJulayi 2019, uMnyango Wezindlu Nokuthuthukiswa Kwezindawo Zasemakhaya wavuma ngokulandelana izinhlelo zokuhlola zaseShandong, Zhejiang, Henan, Jiangxi, Hunan, Sichuan, Qinghai kanye nezinye izifundazwe eziyisikhombisa ukukhuthaza ukusungulwa kohlelo lokwakha izindlu ezakhiwe ngaphambili lwesakhiwo sensimbi esivuthiwe.

Ngaphansi kwethonya lezinqubomgomo ezinhle, isidingo semakethe nezinye izici, indawo entsha yokwakha izakhiwo ezenziwe ngesakhiwo sensimbi ikhuphuke cishe ngo-30%. Umkhiqizo wesakhiwo sensimbi sikazwelonke ukhombisa nokukhula okuqhubekayo unyaka nonyaka, ukhuphuka kusuka kumathani ayizigidi ezingama-51 ngo-2015 kuya kumathani ayizigidi ezingama-71.2 ngo-2018. Ngo-2020, umkhiqizo wesakhiwo sensimbi udlule amathani ayizigidi ezingama-89, okwenza kube ngu-8.36% wensimbi eluhlaza,
