Ukusetshenziswa kwe-calcium formate: zonke izinhlobo zodaka lwengxube eyomile, zonke izinhlobo zikakhonkolo, izinto ezingagugi, imboni yaphansi, imboni yokuphakelayo, ukushuka. Inani le-calcium formate licishe libe ngu-0.5 ~ 1.0% ngethani lodaka olomile nokhonkolo, kanti inani eliphakeme lokwengezwa ngu-2.5%. Inani le-calcium formate liyakhula kancane kancane ngokuncipha kwezinga lokushisa, futhi noma inani lika-0.3-0.5% lisetshenziswa ehlobo, lizodlala umphumela omkhulu wamandla wangaphambi kwesikhathi.
I-calcium formate ine-hygroscopic kancane futhi inambitheka ngokubaba kancane. Imaphakathi, ayinabo ubuthi, inyibilika emanzini. Isixazululo esinamanzi asithathi hlangothi. Ukunyibilika kwe-calcium formate akushintshi kakhulu ngokunyuka kwezinga lokushisa, 16g/100g amanzi ku-0℃ kanye no-18.4g/100g amanzi ku-100℃. Amandla adonsela phansi athile: 2.023(20℃), ukuminyana kwenqwaba 900-1000g/L. Izinga lokushisa lokubola lokushisisa>400℃.
Ekwakhiweni, isetshenziswa njenge-ejenti yokumisa ngokushesha, i-lubricant kanye ne-ejenti yamandla yokuqala usimende. Isetshenziselwa ukwakha udaka kanye nokhonkolo ohlukahlukene, sheshisa ijubane lokuqina likasimende, unciphise isikhathi sokumisa, ikakhulukazi ekwakhiweni kwasebusika, ukugwema izinga lokushisa eliphansi lokusetha ijubane lihamba kancane kakhulu. Fast demoulding, ukuze usimende ngokushesha ngangokunokwenzeka ukuthuthukisa amandla asetshenziswa.
I-asidi ye-formic ihlukaniswa nge-lime e-hydrated ukuze ikhiqize i-calcium formate, futhi i-calcium formate yokuhweba itholakala ngokucwengisiswa. I-sodium formate kanye ne-calcium nitrate zithola ukubola okuphindwe kabili phambi kwe-catalyst ukuze kutholwe i-calcium formate futhi kukhiqize ngokubambisana i-sodium nitrate. I-calcium formate yezentengiselwano itholwe ngokucwengisiswa.
Enkambweni yokukhiqizwa kwe-pentaerythritol, i-calcium hydroxide isetshenziselwa ukuhlinzeka ngezimo eziyisisekelo zokusabela, futhi i-calcium formate ikhiqizwa ngokungeza i-formic acid ne-calcium hydroxide ngesikhathi sokungathathi hlangothi.
I-anhydrous formic acid ingatholakala ngokuxuba i-formic acid ne-phosphorus pentoxide kanye ne-distillation ngaphansi kwengcindezi encishisiwe, ephindaphindiwe izikhathi ezingu-5 kuya kwezingu-10, kodwa inani liphansi futhi lidla isikhathi, okuzobangela ukubola okuthile. I-distillation ye-formic acid ne-boric acid ilula futhi iyasebenza. I-boric acid iphelelwa amanzi ekushiseni okuphezulu okuphakathi kuze kube yilapho ingasakhiqizi ama-bubbles, futhi ukuncibilika okubangelwayo kuthululelwa eshidini lensimbi, lipholiswe esomisini, bese ligaywa libe yimpuphu.
I-borate phenol powder enhle yengezwe ku-asidi ye-formic futhi yabekwa izinsuku ezimbalwa ukuze yakhe isisindo esiqinile. Uketshezi olucacile lwahlukaniselwa ukucwiliswa kwe-vacuum kanye nengxenye yokugaya engu-22-25 ℃/12-18 mm yaqoqwa njengomkhiqizo. Okumile kufanele kuhlanganiswe ngokugcwele futhi kuvikelwe ngepayipi elomisa.
Gcina endaweni epholile, engenisa umoya. Gcina kude nomlilo nokushisa. Izinga lokushisa le-reservoir akufanele lidlule ku-30 ℃, futhi umswakama ohlobene akufanele udlule u-85%. Gcina isitsha sivaliwe. Kufanele igcinwe ngokuhlukana nama-oxidizers, ama-alkali nezimpushana zensimbi ezisebenzayo, futhi akufanele ixutshwe. Ifakwe izinhlobonhlobo ezihambisanayo kanye nenani lamathuluzi omlilo. Indawo yokugcina kufanele ifakwe izinto ezivuzayo zokwelapha izimo eziphuthumayo kanye nezinto ezifanele zokuvikela.
