Calcium formate inoshandisa: marudzi ese edhaka rakaomarara musanganiswa, marudzi ese ekongiri, zvinhu zvinopfekwa, indasitiri yepasi, indasitiri yezvekudya, kusukuta. Huwandu hwecalcium formate hunenge 0.5 ~ 1.0% patani yedhaka rakaoma uye kongiri, uye iyo yakanyanya kuwedzera huwandu ndeye 2.5%. Huwandu hwecalcium formate hunowedzerwa zvishoma nezvishoma nekudzikira kwetembiricha, uye kunyangwe huwandu hwe 0.3-0.5% hukaiswa muzhizha, hucharidza yakakosha simba rekutanga.
Calcium formate ine hygroscopic zvishoma uye inonaka zvishoma. Neutral, non-chepfu, soluble mumvura. Iyo aqueous solution haina kwayakarerekera. Kunyungudika kwecalcium formate hakuchinji zvakanyanya nekuwedzera kwekushisa, 16g/100g mvura pa0℃ uye 18.4g/100g mvura pa100℃. Chaiyo giravhiti: 2.023(20℃), kuwanda density 900-1000g/L. Heating decomposition tembiricha >400 ℃.
Mukuvaka, inoshandiswa seyekukurumidza kuseta agent, lubricant uye yekutanga simba mumiriri we simenti. Inoshandiswa mukuvaka dhaka nekongiri yakasiyana-siyana, kurumidza kuomesa simiti, kupfupisa nguva yekuisa, kunyanya mukuvaka kwechando, kudzivirira kuderera kwekushisa kwekumisa kukurumidza kunonoka. Fast demoulding, kuitira kuti simende nokukurumidza sezvinobvira kuvandudza simba kuisa mukushandisa.
Formic acid inodzorwa ne hydrated lime kuti igadzire calcium formate, uye yekutengesa calcium formate inowanikwa nekunatsa. Sodium formate uye calcium nitrate inopinda kaviri decomposition reaction muhupo hwecatalyst kuti iwane calcium formate uye inogadzirisa sodium nitrate. Commercial calcium formate yakawanikwa nekunatswa.
Mukuita pentaerythritol kugadzirwa, calcium hydroxide inoshandiswa kupa basic reaction conditions, uye calcium formate inogadzirwa nekuwedzera formic acid uye calcium hydroxide mukuita neutralization.
Anhydrous formic acid inogona kuwanikwa nekusanganisa formic acid ne phosphorus pentoxide uye distillation pasi pekumanikidzwa kwakaderedzwa, inodzokororwa 5 kusvika ku10 nguva, asi mari yacho yakaderera uye inopedza nguva, iyo inokonzera kumwe kuora. Iyo distillation ye formic acid uye boric acid iri nyore uye inoshanda. Iyo boric acid inoshambidzwa pamhepo yakadzika yepamusoro kusvika isingachabudisi mabhubhu, uye iyo inoguma inonyungudika inodururwa papepa resimbi, yakanyoroveswa muomesi, uye yobva yakuyiwa kuita upfu.
Iyo yakanaka borate phenol powder yakawedzerwa kune formic acid uye yakaiswa kwemazuva mashomanana kuti iite yakaoma yakawanda. Iyo yakachena mvura yakapatsanurwa kuti vacuum distillation uye iyo distillation chikamu che22-25 ℃/12-18 mm chakaunganidzwa sechigadzirwa. Iyo ichiri ichave yakazara pasi yakabatana uye yakachengetedzwa neinoomesa pombi.
Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Ramba kure nemoto nekupisa. Kupisa kwemvura hakufaniri kudarika 30 ℃, uye hunyoro hunenge husingapfuuri 85%. Chengetedza mudziyo wakavharwa. Inofanira kuchengetwa zvakasiyana kubva kune oxidizers, alkalis uye inoshanda simbi poda, uye haifaniri kusanganiswa. Yakashongedzerwa nemhando inoenderana uye huwandu hwemidziyo yemoto. Nzvimbo yekuchengetera inofanirwa kuve nemidziyo inovuza yekurapa yekukurumidzira uye yakakodzera midziyo yekuchengetera.
