Yintoni i-barium yentsimbi?

I-Barium yindawo yentsimbi ye-alkali ene-Alkaline yentsimbi, inqanaba lesithandathu leqela le-IIA yeqela kwitheyibhile ye-IIA kwitheyibhile yamaxesha, kunye nento esebenzayo kwi-Alkaline yentsimbi yesinyithi.

1, Ukuhanjiswa komxholo

I-Barium, njengezinye iindawo zase-Alkaline zomhlaba, zisasazwa naphi na emhlabeni: umxholo kwi-crust ephezulu yi-0.026%, ngelixa ixabiso eliphakathi kwi-Crust yi-0.022%. I-Barium ikakhulu ikho ngohlobo lwe-barite, i-sulfate okanye i-carbonate.

Eyona minerals eziphambili ye-Barium ye-Barium yeNdalo yi-Barite (baso4) kunye ne-Wirite (Baco3). Iidipozithi ze-barite zisasazwa ngokubanzi, ngeedipozithi ezinkulu eHunan, Guangxi, Shandong kunye nezinye iindawo e China.

I-2, ifildi yesicelo

1. Ukusetyenziswa kwezamashishini

Isetyenziselwa ukwenza iityuwa zebharium, izabelo, izinto zokucima umlilo, ii-nuclear, njl.

Isetyenziswe ngokubanzi kwi-alloys, enjengokukhokela, i-calcium, i-magnesium, i-sodium, i-lithium, ialuminium kunye ne-nickel.

I-Barium yentsimbiIngasetyenziselwa iarhente yokufumana amandla yokususa igesi kwiityhubhu ze-vacuum kunye ne-tuby imifanekiso, kunye ne-arhente yokufaka i-Danish yokuphucula izinyithi.

I-Barium Niture ixutywe ne-potassium chlorate, i-magnesium powder kunye neRosin inokusetyenziswa ukwenza imiqondiso kunye kunye nemililo yomlilo.

Iikhonkrimu zebhanti ezinyibilikayo zihlala zisetyenziswa njengezibulala-zinambuzane, ezinje nge-barium chloride, ukulawula iintlobo ezahlukeneyo zezityalo.

Ingasetyenziselwa kwakhona ukucoca i-brine kunye namanzi e-boiler yemveliso ye-cheustic ye-cheustic soda.

Ikwasetyenziselwa ukulungiselela imiphetho. Imizi-mveliso yendwangu kunye nezikhumba zisetyenziswa njenge-morder kunye ne-rayon yokutshata.

2. Ukusetyenziswa kwezonyango

I-Barium Isfalfate sisiyobisi esincedayo soviwo lwe-X-ray. Umgubo omhlophe ngaphandle kwevumba kunye nephunga, elinokubonelela ngokwahlukileyo emzimbeni ngexesha loviwo lwe-X-ray. I-calfate ye-Barium ye-Barium ayithanga kwiphecana le-gestrointernal kwaye alinantsingiselo yokuphendula. Ayiqulatha iziqu ezinyibilikayo ezifana ne-barium chloride, i-barium sulfide kunye ne-barium carbonate. Isetyenziselwa ikakhulu i-gestrointentinal radiology kwaye ngamanye amaxesha ngamanye amaxesha kwezinye iinjongo.

3,Indlela yokulungiselela

Kwimizi-mveliso, ukulungiswa kwesinyithi sebharium yahlulwe yangamanyathelo amabini: Ukulungiswa kwe-Barium Oxide kunye nokuncitshiswa kwentsimbi

Kwi-1000 ~ 1200 ℃, ezi ndlela zimbini zinokuvelisa inani elincinci le-Barium. Ke ngoko, impompo yevacuum kufuneka isetyenziselwe ukuqhubeka nokudlulisela i-barrium vapor kwindawo yokuphendula kwindawo yokufundisa ukuze impendulo iqhubeke nokuqhubeka ngasekunene. Intsalela emva kokuphendula iyityhefu kwaye inokulahlwa kuphela emva konyango.

4,Amanyathelo okhuseleko

I-1. Iingozi zeMpilo

I-Barium ayisiyonto ibalulekileyo ebantwini, kodwa ityhefu. Ukutya amakhonkco anyibilikayo anobangela wetyhefu kuya kubangela ityhefu ye-barium. Ukuthatha ukuba ubunzima bomntu omdala ngama-70kg, inani lilonke le-barium emzimbeni wakhe limalunga ne-16mg. Emva kokuthatha i-barium ityiwa ngempazamo, iya kutshitshiswa ngamanzi kunye nesisu, okukhokelele kwizigameko ezininzi zetyhefu kunye nokufa okuthile.

Iimpawu zetyhefu ye-barium ye-barium ye-Barium: Ityhefu ye-Barium ye-Barium ibonakaliswa njengokucaphuka kwe-gescostinal kunye ne-hypyemili, i-quadriplegia, ukubandakanyeka kwe-quadcy, i-quadcleging, i-quadclerial sukrala i-gestrointenal Njengokugabha, isisu esibuhlungu, isifo sohudo, njl njl.

2. Uthintelo lwe-Hazard

Ukuvuza kunyango olungxamisekileyo

Yahlula indawo engcolisekileyo kwaye uthintele ukufikelela. Sika umthombo wokukhuphela. Kucetyiswa ukuba abasebenzi abanonyango olungxamisekileyo bathwale imaski yokucoca uthuli kunye nempahla yokukhusela umlilo. Ungaqhagamshelana ngqo nokuvuza ngokuthe ngqo. Inani elincinci lokuvuza: Khusela ukuphakamisa uthuli kwaye uqokelele kwisikhongozeli esomileyo, ecocekileyo nesigubungela nesigqubuthelo kwifosholo ecocekileyo. Dlulisa ukuphinda usebenzise kwakhona. Isixa esikhulu sokuvuza: I-Cover ngendwangu yeplastiki kunye ne-canvas ukunciphisa ukubhabha. Sebenzisa izixhobo ezingafakwanga ukuhambisa kunye nokuphinda usebenzise kwakhona.

3. Amanyathelo okhuselo

Ukukhuselwa kwenkqubo yokuphefumla

Ukukhuselwa kwamehlo: Ngena i-goggles yokhuseleko lweekhemikhali.

Ukukhuselwa komzimba: Ngenisa impahla yokukhusela iikhemikhali.

Ukukhuselwa kwezandla: nxiba iigloves zerabha.

Abanye: Ukutshaya akuvumelekanga kwindawo yomsebenzi. Nikela ingqalelo kwi-hygiene yobuqu.

5, Ukugcina kunye nokuhamba

Gcina kwindawo epholileyo nenomoya. Hlala kude nemithombo yobushushu kunye nemithombo yobushushu. Ubumnene bemincili bugcinwa ngezantsi kwe-75%. Iphakheji iya kutywina kwaye ingabinakho ukunxibelelana nomoya. Ifanele igcinwe ngokwahlukeneyo kwii-oxidants, i-AIDS, ialkalis, njl., Kwaye akufuneki idityaniswe. Ukuqhushumba Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ekulula ukuvelisa iintlantsi. Indawo yogcino iya kuxhotyiswa ngezinto ezifanelekileyo zokuqulatha ukuvuza.
