Sodium formate: ukukhiqizwa, izakhiwo kanye nezicelo

Kukhona amakhemikhali abaningi ezenza ukuphila kube lula ukuze umuntu yesimanje. Omunye walena uwukuba sodium formate. Ifomula lokhu kwakwakhe - HCOONa. Liphinde kuvame ukubizwa ngokuthi i-sodium formate.

Uhlolojikelele

Sodium formate kuyinto eceleni ekhiqizwa ngesikhathi ukukhiqizwa pentaerythritol. Le nto avame ukusetshenziswa njengendlela agent ekunciphiseni organic zamagama ukusabela. Ukulungiselela sodium formate lihlotshaniswa izinkinga ezithile ukuhlanzwa lokhu kwakwakhe. Ngakho, ngo-okwaphuma lapho kuyilo kuhlale admixture kancane pentaerythritol nemikhiqizo yalo. Sodium formate - kuyinto powder crystalline, umbala omhlophe noma kancane lemicu empunga elinamathela othini. Ngezinye izikhathi ukudayiswa ihlangabezana sodium formate nge Tint kancane ogqamile. Ukungcola abanazo awabonakali ngokubona okubonakala ngeso lenyama. I powder, okuyinto akhangiswe ngayo, i-ingxenyenamba mass we ketshezi eziyisisekelo kufanele kube hhayi ngaphansi kuka-92%. Qualitatively, sodium formate isisindo ezithile amanzi kumele singeqi 3%. Kuleso imithi kanye okokunandisa. Ngokuya okuqukethwe kwabo glucose awakwazi ukweqa 1%.

Kuze kube manje, akukho olulodwa ukukhiqizwa yezimboni yalesi zamakhemikhali. Njengoba i-sodium formate ikhiqizwa njengoba leyavela, idinga ezengeziwe ukucutshungulwa ekhethekile ubuchwepheshe. Ezinye izinkampani zama synthesize yalolu ketshezi, kodwa ukukhiqizwa enjalo eqolo futhi asifanele ekukhiqizweni.

Ifomula sodium formate - HCOONa. Njengoba le nto iqukethe formic acid okuyinto enhle kakhulu protivolednym reagent ke ngokuvamile kakhulu esetshenziswa njengoba emelana nokubanda enhlanzini yasezindaweni.

Izakhiwo sodium formate

Manufactured lobuchwepheshe sodium formate isetshenziswa izimboni eziningana. yokusetshenziswa kwawo kabanzi ngenxa izakhiwo. Le into kuyinto encibilikayo kakhulu emanzini. Kuyinto kancane oncibilikayo utshwala zingaxazululeki ether. Sodium formate akuyona esikhanyayo ngokugcwele ukuqhuma-ubufakazi. Naphezu kwakho konke lokhu, ezindaweni wesitoreji futhi isicelo awukwazi ukusebenzisa i ilangabi evulekile nokubhema zivinjelwe.

Izindawo kwesicelo chemical

Isetshenziselwa njengenhlangano okufakiwe emelana nokubanda enhlanzini yasezindaweni ekukhiqizeni ezihlukahlukene wokwakha izakhiwo. It is libuye lisetshenziswe umkhakha ukushuka. Isetshenziselwa emikhakheni ehlukahlukene yokuhlinza preddubilnyh.

I formate sodium njengoba impahla eluhlaza lubaluleke ekukhiqizeni ezifana chemical njengoba formic acid. Iphinde isetshenziselwe embonini kawoyela kanye njengendlela wengxenye ye-anti-Uqweqwe ejenti.

Umthelela emzimbeni womuntu

Sodium formate e degree kwabo ukuchayeka womuntu okukhulunywe 4 ikilasi of ingozi. Kungabangela umonakalo omkhulu emzimbeni e lokuhlala eliphezulu. Sodium formate ngokuvamile kubangela ukucasuka ukuze nolwelwesi lwamafinyila kanye engenhla ipheshana zokuphefumula. Ngo asebenta nalelicembu chemical kumele kusetshenziswe PPE: wokuphefumula, ingubo, amagilavu zenjoloba. Uma kwenzeka ingozi ukukhululwa esiningi sodium formate iyadingeka ukusebenzisa buso igesi. Ukuze isitoreji amakhemikhali omile ifakwe emafektri elingalodwa, lapho agcinwe emasakeni Pallets ekhethekile.

Sodium formate - emelana nokubanda enhlanzini yasezindaweni

Ngaphezu kwalokho ukusebenzisa umkhakha nokwakhiwa, yalolu ketshezi ngenkuthalo esetshenziswa njenge-agent emelana nokubanda enhlanzini yasezindaweni nge engashiyi umphumela. Yena, ngokungafani nezinye izinhlobo anti-Uqweqwe ejenti, ayinayo umthelela inhlekelele phezu imvelo. Ngaphezu kwalokho, kusukela it is hhayi kakhulu abathintekayo metal izingxenye zezimoto. Its mahhala futhi ingasetshenziswa for ekwelapheni izakhiwo ezenziwe umuntu phezu izindawo zomgwaqo njengoba inhibitor ukugqwala.

Sodium formate Ukwakhiwa

Lokhu chemical lubaluleke ukwakhiwa ngokhonkolo Monolithic futhi wasisekela izakhiwo zikakhonkolo ngenkathi ezibandayo. Ngaphezu kwalokho, kunconywa ukuyisebenzisa ngisho nalapho izinga lokushisa komoya - 5 ° C. It is libuye lisetshenziswe ukukhiqizwa monoliths e izakhiwo Precast ngoba uphawu amalunga omzimba, ngoba Precast imikhiqizo ukhonkolo. Sodium formate is busuka ingxube aphathekako olinganise ezilandelayo:

• 2% ngesisindo sezinti usimende esetshenziswa ngokuya chemical ezomile is lukhuni ezingeni lokushisa kuze kufinyelele -5 ° C (umthamo 8 kg / L 7);

• 3% - ukuba -10 ° C (12 kg / 10.5 L);

• 4% - ukuba -15 ° C (16 kg / 14 L).

Phakathi ukulungiselela ngokhonkolo ne-sodium formate ziyoncibilika ngamanzi afudumele. Kulokhu kukhona izincomo esikhethekile ukuxuba lokhu isixazululo. Ngakho, it is wanezela kanye emanzini ukuxuba ngokusebenzisa ekhethekile dispenser amakhemikhali izithasiselo. Ungasebenzisa futhi i-dispenser amanzi. Kulo mBhalo, ukuxutshwa kuyadingeka ukunciphisa ukusetshenziswa yayo nge 8-13%. Ngenxa formate sodium kuyinto ukusheshisa ukuqina ukhonkolo, okuyinto efanele ikakhulukazi ukwakhiwa ephezulu liphumele izakhiwo.

izinyathelo zokuqapha

Le nto ayikwazi lisetshenziswe ezakhiwe zangaphambi wagcizelela, lapho steel esetshenziselwa yokugcizelela amakilasi AT-VI, AT-IV, A-V. Futhi, asifanele eziphathekako ukhonkolo imikhiqizo sizosetshenziswa igesi namanzi izindawo nge umswakama okukhulu kuka-60% futhi ezakhiwe eyenzelwe amabhizinisi ezimbonini kanye ezokuthutha gesi, lapho DC isetshenziswa.

Uma usebenzisa le nto kufanele sikhumbule ukuthi kusenzima hhayi "gostirovano" njengoba emelana nokubanda enhlanzini yasezindaweni, ngakho kuphela ukusebenzisa ulwazi ngakho, elisetendeni komphakathi "Izincomo on ukusetshenziswa sodium formate lobuchwepheshe". Lesi sakamuva zavunyelwa yikomidi uchwepheshe we yezesayensi nasezinzuzweni lobuchwepheshe NIISK Council. abakhiqizi eziningi zamakhemikhali ezikhishwe yayo ezibekiweko lobuchwepheshe (TU). Kuze kube manje, ukudayiswa kwemikhiqizo okutholakala China, akunakwenzeka ukuqinisekisa ukuthi ikhwalithi nje kaningi lokho akusho ngisho babe izitifiketi. Yingakho kungcono ukuthenga izinto abakhiqizi okunokwethenjelwa yasekhaya.
