Yavaibvisa sulphide

Sulfide ndiyo yavaibvisa (sodium sulphide hwokugadzira) ndiyo remubatanidzwa iro zvinowanzoshandiswa indasitiri. Saka, fuma iri rinoshandiswa simbi, kemikari, chiedza bhizimisi uye mamwe maindasitiri. Yavaibvisa sulphide, kunyanya kushandiswa mune zvaAtemisi pulp, madhayi, iri kubudiswa wamatehwe. Fuma rinoshandiswa kunyunguduka vamwe vasiri ferrous simbi. Yavaibvisa sulfide hunokosha pasango Analytical kemisitiri. Rinoshandiswa senzira reagent muzvirongwa siyana.

Yavaibvisa sulphide. Formula (Na2S)

The zvinoitika mumuviri ezvinhu nyaya anonzi homogeneous guru, sezvamakaropafadzwa mukuru-wanda, kana hygroscopic crystals. The fuma anogadzirwa muchimiro monolith 3 tsika dziri particulate muchimiro (muchimiro flakes kana granules). Shandisa akabvumira chigadzirwa une chiedza mashava, hapana yeyero kana grayish ruvara. More zvikuru kana mumwe ruvara anoratidza inokosha oxidation nevamiririri. Kwakadaro yavaibvisa sulfide uye anorasikirwa zvinobatsira zvivako kukodzera kuti zvinobatsira. The hwokugadzira chinangwa chigadzirwa rine kubva makumi matanhatu matatu kusvika matanhatu navanomwe muzana muzasi zvinhu pasi ezvinhu kuti vakawanda chikamu ari insoluble vakasara haasi kupfuura hafu muzana.

Zvinoenderana kupatsanura pakati chechetere nengozi kuti Sodium dzevanhu sulfurous basa kirasi yechipiri. The fuma iri inflammable uye putika. Nezvenyaya iyi, zviri nani kuti achengetere acho namahwindo mumakamuri dziri vakapakata zvivako zvose zvinodiwa kuitira moto kwakachengeteka. Hazvina yakarumbidza kubvisa pasuru pamwe chigadzirwa kusvikira zvakananga pokushandisa fuma. Nepo kuramba kuvimbika mumidziyo yavaibvisa sulfide inogona kuchengetwa kwemakore maviri. Term Kushandisa hazvisi chete pagore.

Transportation of chigadzirwa yaifanira angambosvika pakufamba mu namahwindo ngoro kana mumagaba. Zvizhinji kutarisirwa inofanira kubhadharwa kuti vachizvitakudza uye vachidzikisa zvinhu, kunyanya kana zvinofungirwa zvakananga kuonana chigadzirwa, mumapepa mu tefa mumagaba. Panguva chokufambisa kudzivisa kwekanguva okuchengetera munzvimbo rakazaruka dzoga kana depots, taita akashongedzerwa kuita izvi.

Technical yavaibvisa sulfide Chinese kugadzirwa rakazara muna chaiyo muhomwe kuti maviri nemashanu makirogiramu. Kavha anodzivirira kubva nguva isati yakwana oxidation uye kuona chiedza. Uyezve, sezvo kavha simbi ngoma anoshandiswa chete namakemikari zvigadzirwa, Midziyo (CK-1-5 (7)), kana sezvo nyoro midziyo yokushandisa chete. The fuma inogona mumapepa pepa mumasaga (four- kana shanu-rukoko) pamwe yomukati liner - polyethylene bhegi. The mabhegi zvingava mambure kurema haasi makirogiramu anopfuura makumi mashanu.

Dzaizara mu inokosha midziyo fuma iri kuendeswa kune ari tikaisa wemari rakavhurika mhando.

Product arambe achirema iri 1,856 giremu paavhareji cubic sendimita. Kubvunda tembiricha rinosvika 1180 inegumi. The chigadzirwa iri zvikuru hygroscopic. In mvura pa madhigirii maviri ichiputswa 13.6% pa 97,5 madhigirii - 45% of zvinhu. The chigadzirwa anokwanisa rokuumba crystalline hydrates. For aqueous zvingaitwa kuti yavaibvisa sulfide hwokugadzira noruzhinji alkaline kuita.

The hydrolysis rinoitwa pamwe yavaibvisa sulphide uyewo munyu izvo vakaumba kusimba asidhi uye simba chawo. Phenolphtalein vari bvunzo chubhu ine mhinduro anova rwepingi. Izvi zvinoratidza kuti alkaline svikiro achiumbwa pabvunzo chubhu. Saka, yavaibvisa sulfide, uyewo dzimwe munyu izvo vakaumba kusimba asidhi uye simba chawo, hydrolysed kuti aumbe somugumisiro alkali.
