Ukusetyenziswa kwe-calcium fomati

Ukusetyenziswa kwefomati yeCalcium: zonke iintlobo zodaka oluxubeneyo olomileyo, zonke iintlobo zekhonkrithi, izixhobo ezinganxibiyo, ishishini lomgangatho, ishishini lokutya, ukusukwa. Isixa se-calcium formate simalunga ne-0.5 ~ 1.0% ngetoni yodaka olomileyo kunye nekhonkrithi, kwaye ubuninzi bokongeza imali yi-2.5%. Isixa se-calcium formate sinyuswa kancinci kancinci ngokuhla kweqondo lobushushu, kwaye nokuba isixa se-0.3-0.5% sisetyenziswa ehlotyeni, siya kudlala isiphumo samandla sakwangoko.
I-calcium formate i-hygroscopic kancinane kwaye incasa ikrakra kancinane. Ingathathi hlangothi, ayinayo ityhefu, inyibilika emanzini. Isisombululo samanzi singathathi hlangothi. I-solubility ye-calcium formate ayitshintshi kakhulu ngokunyuka kwamaqondo obushushu, i-16g/100g yamanzi ku-0℃ kunye ne-18.4g/100g yamanzi kwi-100℃. Umxhuzulane okhethekileyo: 2.023(20℃), ubuninzi bobuninzi 900-1000g/L. Iqondo lobushushu lokubola>400℃.
Ekwakhiweni, isetyenziswe njenge-arhente yokumisa ngokukhawuleza, i-lubricant kunye ne-ejenti yamandla okuqala kwi-samente. Isetyenziswe kwisakhiwo sodaka kunye nekhonkrithi eyahlukeneyo, khawuleza isantya sokuqina kwesamente, unciphise ixesha lokumisa, ngakumbi kulwakhiwo lwasebusika, ukuphepha isantya sokumisa ubushushu obuphantsi bucotha kakhulu. Ukudilizwa ngokukhawuleza, ukuze isamente ngokukhawuleza kunokwenzeka ukuphucula amandla asetyenziswe.
I-asidi ye-formic ithotywa ngekalika e-hydrated ukuvelisa i-calcium formate, kunye ne-fomate ye-calcium yorhwebo ifunyanwa ngokusulungekiswa. I-sodium formate kunye ne-calcium nitrate iphinda idibane ngokuphindwe kabini phambi kwe-catalyst ukufumana i-calcium fomati kunye nokuvelisa i-nitrate ye-sodium. Ifomati ye-calcium yorhwebo yafunyanwa ngokucokiswa.
Kwinkqubo yokuvelisa i-pentaerythritol, i-calcium hydroxide isetyenziselwa ukubonelela ngeemeko ezisisiseko zokuphendula, kunye ne-calcium fomate iveliswa ngokungeza i-acid ye-formic kunye ne-calcium hydroxide kwinkqubo yokungathathi hlangothi.
I-Anhydrous formic acid inokufumaneka ngokuxuba i-asidi ye-formic kunye ne-phosphorus pentoxide kunye ne-distillation phantsi koxinzelelo oluncitshisiweyo, ngokuphindaphindiweyo amaxesha ama-5 ukuya kwe-10, kodwa inani liphantsi kwaye lidla ixesha, eliya kubangela ukubola okuthile. I-distillation ye-fomic acid kunye ne-boric acid ilula kwaye iyasebenza. I-asidi ye-boric ihlanjululwe kwiqondo lokushisa eliphakathi kuze kube yilapho ingasavelisi amaqamza, kwaye isiphumo esincibilikayo sigalelwa kwiphepha lentsimbi, lipholile kwi-dryer, kwaye emva koko ligaywe libe ngumgubo.
I-borate ecocekileyo ye-phenol powder yongezwa kwi-asidi ye-formic kwaye ibekwe iintsuku ezimbalwa ukwenza ubunzima obunzima. Ulwelo olucacileyo lohlulwe kwi-vacuum distillation kunye nenxalenye ye-distillation ye-22-25 ℃/12-18 mm yaqokelelwa njengemveliso. Indawo emileyo iyakuhlala idityaniswe ngokupheleleyo kwaye ikhuselwe ngombhobho wokomisa.
Gcina kwindawo epholileyo, nengena umoya. Zigcine kude nomlilo nobushushu. Ubushushu bendawo yokugcina amanzi abuyi kuba ngaphezu kwe-30℃, kwaye ukufuma okuhambelanayo akuyi kudlula i-85%. Gcina isitya sivaliwe. Kufuneka igcinwe ngokwahlukileyo kwi-oxidizers, i-alkali kunye ne-powders yensimbi esebenzayo, kwaye akufanele ixutywe. Ixhotyiswe ngeentlobo ezihambelanayo kunye nobuninzi bezixhobo zomlilo. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo ezifanelekileyo zokuthintela.
