Sodium nikuda: imveliso, iimpawu kunye nezicelo

Kukho iikhemikhali ezininzi ezenza ubomi lula ukuba umntu namhlanje. Enye yezi sodium nikuda. Ifomula yale compound - HCOONa. Kwakhona elikholisa ukubizwa ngokuba sodium nikuda.

Overview

Sodium nikuda yi eceleni kuveliswa ngexesha imveliso pentaerythritol. Le nto ezininzi eziqhele ukusetyenziswa njenge arhente kuncitshiswa xa ngayo yokuqaphela organic. Ukulungiswa sodium nikuda lu dityanisiwe iingxaki ezithile nokusulungekiswa le ezimbaxa. Ngoko, kwi imveliso isiphelo kusoloko admixture kancane pentaerythritol kunye nezakhi zayo. Sodium nikuda - i ngumgubo crystalline, umbala omhlophe okanye nombala kancinane. Ngamanye amaxesha ukuthengiswa lidibana sodium nikuda kunye ithinti kancinane zana. Elimsulwa abafumaneka kulo alubonakali ngeliso lenyama. I-powder, nto leyo ithengiswe, iqhezu ubunzima kwento esisiseko kufuneka ungabi ngaphantsi kwe-92%. Ngokomgangatho, sodium nikuda ubunzima oluthile amanzi kufuneka ngaphezu-3%. In ukuba iikhemikhali yaye sweeteners. Ngokwemiqathango ikuquletheyo glucose ayikwazi igqithe-1%.

Ukuza kuthi ga ngoku, akukho nanye imveliso mveliso yale chemical. Ekubeni sodium nikuda yaveliswa ibe yi-kwimveliso, ifuna ubuchwepheshe processing ekhethekileyo olongezelelweyo. Ezinye iinkampani bazame nokulungelelanisa le into, kodwa imveliso loo lubiza kakhulu kwaye asihambelani imveliso mass.

Ifomula sodium nikuda - HCOONa. Ekubeni le nto iqulethe formic acid leyo reagent protivolednym elihle ukuba ngoyena usetyenziswa rhoqo njengoko nokubanda.

Iimpawu sodium nikuda

Bokwenziwa technical sodium nikuda lisetyenziswa mveliso eziliqela. Its ngokubanzi ukusetyenziswa ngenxa iipropati. Le into enyibilikayo kakhulu emanzini. Kuyinto ezinyibilikayo kancinci utywala ezingenakunyibilika in kaEtere. Sodium nikuda olo alunasikhanyisi ngokupheleleyo dubulo-ubungqina. Nangona oku, iindawo zokugcina kunye isicelo akakwazi ukusebenzisa nomlilo, kunye nokutshaya abavumelekanga.

Iindawo isicelo kwemichiza

Isetyenziswa njengento isongezo isinqandi ekuvelisweni iintlobo zezakhiwo yokwakha. Iyasetyenziswa kwishishini kwezikhumba le. Oku kusetyenziswa kwimisebenzi eyahlukeneyo preddubilnyh.

I-sodium nikuda njengokuba izinto ekrwada buyafuneka ekuvelisweni ezifana imichiza njengoko formic acid. Iyasetyenziswa kwishishini oyile kwaye njengenxalenye arhente ezilwa icing.

Impembelelo emzimbeni womntu

Sodium nikuda okukwiqondo yabo sesichengeni kwabantu ekubhekiselwe kuwo 4 udidi yingozi. Oku kunokubangela umonakalo omkhulu umzimba kungomlinganiselo eziphakamileyo. Sodium nikuda kubangela eku- ukuba inwebu yangaphakathi kunye phecana eliphezulu zemiphunga. Xa usebenza nale khemikhali kufuneka zisetyenziswe PPE: baphefumla, iilokhwe, iiglavu zerabha. Kwimeko yengozi kunye nokukhululwa oluninzi sodium nikuda kufuneka asebenzise imaski igesi. Kuba yokugcina omile zixhotyiswe izitora ekwanti, apho igcinwa ezingxoweni kwi pallets ezikhethekileyo.

Sodium nikuda - emelana

Ukongeza ukusebenzisa kushishino kunye nolwakhiwo, le nto aza kusetyenziswa njengearhente isinqandi kunye ndiconga isiphumo. Yena, ngokungafaniyo ezinye iindidi zee-arhente anti-icing, akanayo neempembelelo ezinkulu kokusingqongileyo. Ukongezelela, ukususela oko akuyi kakhulu abachaphazelekayo iindawo metal bezithuthi. Its simahla kwaye zingasetyenziswa ukuba unyango kwezakhiwo ezenziwe kulwakhiwo yendlela njengoko inhibitor umhlwa.

Sodium nikuda Construction

Le chemical buyafuneka ukwenzela ukwakhiwa ngekhonkrithi monolithic nezakhiwo ufakelo lwesamente kwixesha lonyaka ebandayo. Ngaphezu koko, kucetyiswa ukuba usebenzise nokuba xa ubushushu umoya - 5 ° C. Kwakhona kusetyenziswa ekuvelisweni monoliths kwizakhiwo precast ngenxa yokuvalwa amalunga, ngokuba iimveliso precast eziphathekayo. Sodium nikuda yaziswa kwi umxube eziphathekayo kule olinganise zilandelayo:

• 2% ngokobunzima zesamente ezisetyenzisiweyo ngokwemiqathango omile iqaqadekile kwiqondo lobushushu ukuya ku -5 ° C (umthamo 8 kg / L 7);

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

• 4% - ukuya -15 ° C (16 kg / 14 L).

Ngexesha ukulungiswa eziphathekayo kunye nikuda sodium unyityilikiswa emanzini ashushu. Kule meko kukho ingcebiso ekhethekileyo axube le isisombululo. Ngoko ke, idityaniswa kunye namanzi okuxuba ngokusebenzisa ongeziweyo ekhethekileyo kwisixhobo chemical. Unakho ukusebenzisa amanzi. Kwimeko yokugqibela, indlela elisetyenziswa kuyimfuneko ukunciphisa ukusetyenziswa kwayo 8-13%. Ngenxa nikuda sodium yi kwezinga yokuqaqadeka eziphathekayo, nto leyo efanelekileyo ingakumbi ekwakhiweni kwezakhiwo eziphakamileyo.

amanyathelo okhuseleko

Le nto ayikwazi isetyenziswe izakhiwo pre-ndixinezelekile, apho intsimbi esetyenziswa zokomeleza iiklasi AT-VI, AT-IV, A-V. Kwakhona, akukho ezifanelekileyo iimveliso eziphathekayo kunye eziphathekayo eziya kusetyenziswa kwiindawo irhasi kunye namanzi kunye ukufuma mkhulu kuno-60% kwaye izakhiwo ezenzelwe amashishini zoshishino kunye nezothutho umbane, apho kusetyenziswa DC.

Xa kufuneka kukhunjulwe usebenzisa le nto ukuba Nangoku "gostirovano" njengoko nokubanda, ngoko ke sebenzisa kuphela ulwazi malunga nayo, leyo domain zikarhulumente "Izindululo ekusetyenzisweni sodium nikuda technical". Le yokugqibela zivunywe yikomiti nengcali kwabafundi lobunzululwazi nobugcisa NIISK Council. abenzi abaninzi umchiza eyakhutshwa zalo iinkcukacha (DB). Ukuza kuthi ga ngoku, ukuthengiswa kweemveliso ezifumaneka e-China, akunakwenzeka ukuba ukuqinisekisa ukuba umgangatho nje rhoqo awuthethi nto ukuba izatifikethi. Kungenxa yoko le nto kungcono ukuba bathenge izinto kubavelisi zasekhaya ethembekileyo.
