Pasirose - Premier Sodium Sulfide: Kemikari Inokosha Yenzvimbo Dzakasiyana-siyana Dzemaindasitiri
Minda mikuru yekushandisa
Muindasitiri yemapepa, sodium sulfide yedu inoita basa rakakosha mukuita kraft pulping. Inobatsira kuputsa lignin, organic polymer yakaoma inosunga cellulose fibers muhuni. Nekunyungudutsa lignin, sodium sulfide inoita kuti cellulose iparadzaniswe, inova ndiyo chinhu chikuru chinoshandiswa kugadzira mapepa. Izvi zvinoita kuti pulp yemhando yepamusoro ive nesimba uye kupenya kuri nani. Vagadziri vemapepa vanogona kugadzira zvigadzirwa zvemapepa zvakasiyana-siyana, kubva kumapepa matsva kusvika kumapepa ekudhinda emhando yepamusoro, vachishandisa sodium sulfide yedu kuti vawedzere kushanda kwavo zvakanaka uye kunaka kwechigadzirwa.
Indasitiri yemachira inobatsirwawo zvikuru neGlobal - Premier Sodium Sulfide yedu. Inoshandiswa mukubvisa sulfurization yemvere dzemakwai. Makushe anowanzova nezvinhu zvine sarufa zvinogona kukanganisa kunaka kwayo uye kugadziriswa kwayo. Sodium sulfide inobatana nezvinhu izvi, ichibvisa sarufa uye ichivandudza kupfava, ruvara, uye kunaka kwemvere dzemakwai. Pamusoro pezvo, inoshandiswa mune dzimwe nzira dzekudhaya kugadzirisa mamiriro emakemikari, zvichiita kuti jira ritore dhayi zviri nani, zvichiita kuti mavara agare kwenguva refu uye apenye.
Muindasitiri yemigodhi, sodium sulfide chinhu chakakosha chinoshandiswa pakuyerera kwesimbi, kunyanya dzine mhangura, lead, uye zinc. Sodium sulfide inogona kumutsa pamusoro pesimbi idzi, zvichiita kuti dzigamuchire zviri nani kune zvinhu zvinoshandiswa pakuyerera. Izvi zvinovandudza zvakanyanya kushanda kwekuparadzanisa zvicherwa zvinokosha kubva kugangue (dombo remarara), zvichiwedzera mwero wekudzoreredza simbi dzinokosha. Makambani emigodhi anovimba nesodium sulfide yedu kuti ivandudze mashandiro avo ekugadzirisa simbi uye kuwedzera purofiti yavo.
Muindasitiri yematehwe, sodium sulfide yedu inoshandiswa mukusunungura bvudzi. Inobatsira kunyungudutsa mapuroteni ari mubvudzi uye muganda remhuka, zvichiita kuti zvive nyore kubvisa bvudzi. Iri idanho rakakosha mukugadzirwa kwedehwe sezvo richigadzirira dehwe kuti rigadziriswe zvakare. Nekushandisa sodium sulfide yedu yemhando yepamusoro, vagadziri vematehwe vanogona kugadzira dehwe rine pamusoro wakapfava uye magadzirirwo ari nani, zvichisangana nezvinodiwa nemusika wedehwe wepasi rose.

Muchidimbu
Sodium Sulfide yedu yepasi rose - Premier inoiswa mumidziyo yemhando yepamusoro, isina mhepo yakawanda kudzivirira oxidation uye kuve nechokwadi chekuti yagadzikana panguva yekuchengetwa nekutakurwa. Batch yega yega inoongororwa zvakanyanya, kusanganisira kuyedzwa kwekuchena, kuongororwa kwemakemikari, uye kuongororwa kwekushanda. Ungave uri mufekitori wemapepa kuNorth America, fekitori yemachira kuAsia, kambani yemigodhi kuAustralia, kana kambani yeganda kuEurope, sodium sulfide yedu ndiyo mhinduro yakavimbika uye inoshanda zvakasiyana-siyana yaunoda. Inopa mashandiro asingakundike, ichivimbisa kuti inosangana uye inodarika zvinodiwa zvako zveindasitiri.
