Reagents vari zvinhu, pasina pazviri pasingabviri kudzidza kemisitiri

Chero partition kemesitiri kunosanganisira kushandisa zvimwe makemikari. Akapiwa chokwadi chokuti reagents - a fuma kuti anogona kukuvadza kuti utano hwevanhu, kuti okuchengetera yavo inofanira kusvitsa zvimwe zvinodiwa.

boka 7

Chemical reagents muboka iri yakakwirira toxicity, saka placement kwavo, pane zvimwe zvinodiwa. vari yakachengeteka, riri mu laborantskoy. Ane kiyi mubatsiri, uyewo mudzidzisi kemisitiri.

kuchengetera mishonga rakarambidzwa muzvikoro chesekondari, uye mumarabhoritari kuvakuru masangano dzidzo, kuvapo kwavo chete vakabvumira kana chaiyo murayiro kubva musoro tsika. Laboratory anoitisa kuzviomesera kudzora mari zvakadaro zvinokuvadza, manotsi ari magazini chaiyo.

List pamusoro inorganic makemikari vanobvumidzwa kuchikoro murabhoritari

Nyora zvinhu inorganic makemikari, izvo akabvumira kuti kuratidzira kuedza muna kemisitiri zvidzidzo kuchikoro:

• nyore zvinhu: yavaibvisa simbi, crystalline ayodhini, mvura bromine;
• yavaibvisa hydroxide, oxides simbi uye vasiri simbi;
• munyu, kusanganisira kunzwisisa yeimwe, dichromates uye chromates;
• asidhi zvingaitwa.

Organic zvinhu

Cherechedza reagents uye Organic zvinhu izvo kemisitiri mudzidzisi anogona kushandisa pakuumba vechikoro unyanzvi hunobatsira:

• aniline;
• Organic acids;
• benzene;
• phenol;
• formalin.

kune ngozi zvinodiwa kuti makemikari

Safe vakatasva mu laborantskoy kemisitiri kuchengeta reagents, boka 7, dzaiwanzogadzirwa zvokufonongonwa papepa simbi. Akabvumira uye kugadzwa emapuranga mamiriro, kana kunze akachengeteka ari mudungwe nesimbi, pakukora zvisina asingasviki 1 mm.

Pane zvinodiwa uye kuti nzvimbo yakachengeteka. Yandakapiwa reactants ndiyo zvinyorwa ane ngozi, unofanira kusarudza nzvimbo yakachengeteka, saka kuti zvaiva nyore kuti kana moto.

Standard nokurondedzerwa kubva kumusoro vasiri basa zvinhu

Pakati reagents kuti vane ehupfumi zvakafanana, anogona kutaurwa esimbi zingi, calcium, lithium, oxide uye hydroxide, calcium, nitrates simbi iodide, potassium permanganate, potassium, zingi yeimwe. reagents ava zvinhu zviri kuwedzera ngozi, saka, kuedza navo ndivo vanobvumirwa chete pasi zvakananga kutarisira mudzidzisi.

Also kuiswawo pakati pemazita, uye Organic zvinhu zvakadai diethyl Ether, acetone, alcohols, cyclohexane, chloroform, wakaipa mafuta. reagents akadaro zvinhu kuti ine zvainoita huta dzevanhu hurongwa, saka vari kunze kubva pamazita kwemakemikari kugadzirira inoshandiswa muzvikoro kwakajairika dzidzo dzinobatsira basa uye mumarabhoritari kuedza.

The kirasi inogona raitenda (rakakiyiwa) 8 chete boka makemikari anoshandiswa panguva hunobatsira basa uye mumarabhoritari kuedza. reagents akadaro zvinhu kuti vakachengeteka nokuti utano vana. Somuenzaniso, mhinduro ine chloride yavaibvisa sulfate potassium, calcium yakawanda chloride.

chengetedzo Mitemo zvikoro diki

Muzvikoro duku rokumaruwa zvisingakwanisi inosanganisira kuvapo nzvimbo chaiyo pasi laborantskuyu mukamuri, kuchengetera mishonga anofanira kuripa vainyatsotarisirwa. Somuenzaniso, reagent asidhi iyo wevasungwa kuti basa mumiririri kwazvo 50 muzana, vanofanira kuiswa mupurasitiki bhegi iri namahwindo uye akasungirirwa.

Alkalis vari yakasimba ezvinhu, kuva pane imwe rebei kubva acids, kubudikidza kuchengetedza fekitari kavha. Pamusoro nokuvhura guchu yavaibvisa hydroxide kana potassium inofanira zvakasimba kuvharwa, ipapo Vakaisa mapurasitiki mubhegi kana chirongo, iyo zvakasimba kuvharwa ane chimiso.

Chete aqueous mhinduro kuti amoniya uye hydrochloric asidhi ane mukuru mhute kufurirwa, saka zvakakosha kutarisa tightness yacho pasuru. Sezvo mamwe kuchengeteka matanho kana tichishanda reagents izvi anonzi kushandiswa mamwe chisimbiso nguwani, mapepa akasungirwa pamahombekombe.

Kana pasina nzvimbo yoga placement reagents mapoka 2,5,6 akavabvumira mushandirapamwe nzvimbo mune imwe cabinet. Muchiitiko chino, zvakakodzera kuti mumwe boka kutora yoga pasherufu. The yakanakisisa Ipfungwa iri achiisa pamusoro yokumusoro pasherefu pakati reagents, boka 5 pazasi zvinogona yaipiwa nezvinhu mabhanga boka 6, pasi cabinet 2 mapoka kununura reagents.

mhedziso

In sangano dzidzo, izvo zvinofanirwa kuti kushandisa kuti zvidzidzo uye imwe-curricular mabasa mishonga, pane mirayiridzo chaiyo, maererano iyo imwe nzvimbo iri dzinounzwa kwavari. Classic rabhoritari sectional makabhati kushandiswa imba makemikari, mudungwe pamwe ano polymeric zvinhu izvo husingakwanisi kukanganiswa Migumisiro hasha kwezvakatipoteredza.

Pasina rwokudzivirira cladding kwakadaro, zvakakosha kufukidza zvose dzomunyika zvikamu cabinet mafuta pendi muna 2-3 akaturikidzana kuita bumpers pamusoro echiShinto, nekukwirira iyo inofanira kuva 3 cm.

Kuitira kudzivirira echiShinto kubva mumvura, vakagovera akaturikidzana wandei polyethylene firimu. Achiisa fenicha mu laborantskoy kemisitiri rinoitwa pamwe pakuomerera kuchengeta moto vakachengeteka mitemo.

Pamadziro kana ari pamukova laborantskoy kemisitiri mukirasi, anofanira kuva mirayiridzo basa dziviriro, kutenderwa uye chasainwa Kumutungamiriri kupfungwa ane dzidzo, ane mucherechedzo sangano.
