Sodium hydrosulfide inoshandiswa muindasitiri yedhayi seyayamuro pakugadzira organic intermediates uye kugadzira dhayi dzesarufa. Indasitiri yekutsvukisa ganda inoshandiswa kubvisa bvudzi nekutsvaira kwematehwe uye kugadzirisa mvura yetsvina. Indasitiri yefetereza inoshandiswa kubvisa monoma sarufa mune activated carbon desulfurizer. Ndiyo yakabikwa yekugadzirwa kwehafu-yakapera zvigadzirwa zveammonium sulfide uye pesticide ethanethiol. Indasitiri yezvicherwa inoshandiswa zvakanyanya kubatsira mhangura. Inoshandiswa kune sulfite dyeing mukugadzirwa kwemafivha anogadzirwa nevanhu.
Mumusika wepasi rose, sodium hydrosulfide inonyanya kushandiswa mumaindasitiri akadai semamineral processing, mishonga yekuuraya zvipembenene, dhayi, kugadzirwa kwematehwe uye organic synthesis. Muna 2020, saizi yemusika wepasi rose sodium hydrosulfide i10.615 bhiriyoni yuan, gore-pa-gore kuwedzera kwe2.73%. Parizvino, kuburitswa kwegore negore kwe sodium hydrosulfide muUnited States i790,000 matani. Mamiriro ekushandiswa kwe sodium hydrosulfide muUnited States ndeaya anotevera: kudiwa kwe sodium hydrosulfide ye kraft pulp accounts inosvika makumi mana muzana ezvese zvinodiwa, copper flotation inosvika makumi matatu nerimwe muzana, makemikari nemafuta anosvika gumi netatu muzana, uye kugadzirwa kwematehwe kunokwana 31%. 10%, mamwe (kusanganisira mafibhi akaitwa nevanhu uye segphenol ye desulfurization) anoverengera 6%. Muna 2016, saizi yemusika weEuropean sodium hydrosulfide indasitiri yaive 620 miriyoni yuan, uye muna 2020 yaive 745 miriyoni yuan, gore negore kuwedzera kwe3.94%. Muna 2016, saizi yemusika weJapan sodium hydrosulfide indasitiri yaive 781 miriyoni yuan, uye muna 2020 yaive 845 miriyoni yuan, gore negore kuwedzera kwe2.55%.
Kunyangwe indasitiri yenyika yangu yesodium hydrosulfide yakatanga kunonoka, yakasimukira nekukurumidza uye yave chikamu chakakosha cheindasitiri yehupfumi hwenyika yangu. Indasitiri yeSodium hydrosulfide inotora chinzvimbo chakakosha muhupfumi hwenyika. Indasitiri yeSodium hydrosulfide inogona kufambisa kusimudzira kwekurima, indasitiri yemachira, indasitiri yematehwe uye mamwe maindasitiri ane hukama; fambisa kufambira mberi kwesayenzi uye teknolojia uye kukura kwehupfumi hwenyika; kupa uye kuwedzera mikana yemabasa.
Zvinoenderana neGB 23937-2009 industrial sodium hydrosulfide standard, industrial sodium hydrosulfide inofanirwa kuzadzisa zvinotevera zviyero:
Kubva mukupera kwema1960 kusvika pakati pemakore ekuma1990, indasitiri yeChina yesodium hydrosulfide yakagadziridza zvakanyanya uye nekuvandudza maererano nemidziyo yekugadzira, tekinoroji uye maratidziro echigadzirwa. Mukupera kwema1990, kugadzirwa kwe sodium hydrosulfide kwakagadziridzwa kusvika padanho repamusoro rehunyanzvi. Anhydrous sodium hydrosulfide uye crystalline sodium hydrosulfide zvakabudirira kugadzirwa uye kupinda mukugadzirwa kwakawanda. Kare, mukugadzirwa kwe sodium hydrosulfide munyika yangu, zvakaonekwa kuti yakaderera mwero wegiredhi yakakosha uye yakawandisa iron yemukati ndiwo aive matambudziko makuru mukugadzirwa. Kuburikidza nekuenderera mberi nekuvandudzika kwemaitiro ekugadzira, kunaka kwechigadzirwa uye kubuda kwakawedzera, uye mitengo yakadzikira zvakanyanya. Panguva imwecheteyo, nekusimbisa kwenyika yangu pamusoro pekuchengetedzwa kwezvakatipoteredza, tsvina yemvura inogadzirwa nekugadzirwa kwesodium hydrosulfide yakagadziriswa zvinobudirira.
Parizvino, nyika yangu yave mugadziri mukuru pasi rose uye mutengi we sodium hydrosulfide. Sezvo kushandiswa kwe sodium hydrosulfide kuri kuramba kuchigadzirwa, kudiwa kwayo kweramangwana kuchawedzera zvishoma nezvishoma. Sodium hydrosulfide inoshandiswa muindasitiri yedhayi kugadzira organic intermediates uye seanobatsira mugadziri wekugadzira dhayi dzesarufa. Indasitiri yezvicherwa inoshandiswa zvakanyanya mu copper ore beneficiation, mukugadzirwa kwefibers dzakagadzirwa nevanhu kuti sulfite dyeing, etc. Ndiyo yakagadziriswa yekugadzirwa kwesemi-finished zvigadzirwa zveammonium sulfide uye pesticide ethyl mercaptan, uye inoshandiswawo. yekuchenesa mvura yetsvina. Shanduko dzetekinoroji dzaita kuti maitiro ekugadzira sodium hydrosulfide awedzere kukura. Nekuvandudzwa kwemhando dzakasiyana-siyana dzehupfumi uye kukwikwidza kunotyisa, kufambira mberi kwetekinoroji yekugadzirwa kwesodium hydrosulfide kunoderedza kupinza zvakanyanya sezvinobvira kugadzira zvemhando yepamusoro uye zvimwe zvigadzirwa.
