Izici ze-Physicochemical:
1. Uketshezi olungenambala kanye ne-dour ecasulayo.
2. Iphuzu elincibilikayo 16.6 ℃; indawo yokubilisa 117.9 ℃; Iphoyinti elikhanyayo : 39 ℃.
3. Amanzi ancibilikayo, i-ethanol, i-benzene ne-ethyl ether immiscible, engancibiliki ku-carbon disulphide.
Isitoreji:
1. Igcinwe endaweni epholile, nengena umoya.
2. Gcina kude nomlilo, shisa. Isikhathi esibandayo kufanele sigcine izinga lokushisa elingaphezu kuka-16 ° C, ukuvimbela ukuqina. Ngesikhathi esibandayo, izinga lokushisa kufanele ligcinwe lingaphezu kuka-16 DEG C ukuvimbela/ukugwema ukuqina.
3. Gcina isitsha sivaliwe. Kufanele ihlukaniswe ne-oxidant ne-alkali. Ukuxuba kufanele kugwenywe ngazo zonke izindlela.
4. Sebenzisa izibani ezingaqhumi, izindawo zokungena komoya.
5. Imishini kanye namathuluzi avimbela ukusetshenziswa kwezinhlansi okulula ukukhiqiza.
6. Izindawo zokugcina kufanele zifakwe izinto zokwelashwa eziphuthumayo kanye nempahla yezindlu ezifanele.
Sebenzisa:
I-1.Okuphuma kuyo:Isetshenziswa kakhulu ekuhlanganiseni i-acetic anhydride,i-acetic ether,i-PTA, i-VAC/PVA, i-CA, i-ethonone, i-chloroacetic acid, njll.
2.Ezemithi:I-acetic acid njengezinto ezincibilikisayo nezinto zokusetshenziswa kwemithi, ikakhulukazi esetshenziselwa ukukhiqizwa kwe-penicilin G potas-sium, i-penicilin G sodium, i-penicillin procaine, i-acetanilide, i-sulfadiazine, ne-sulfamethoxazole isoxazole, i-norfloxacin, i-ciprofloxacin, i-acetinalic acid, i-acetinalic acid, i-acetinalic acid , i-caffeine, njll.
3.Okumaphakathi:i-acetate,i-sodium hydrogen di,i-peracetic acid, njll
4. Ukuphrinta kwendwangu kanye nokudaya kwendwangu: Isetshenziswa kakhulu ukukhiqiza odayi abahlakazayo namadayi we-vat, nokuphrinta kwezindwangu kanye nokucubungula ukudaya
5. I-synthesis ammonia: Ngendlela ye-cuprammonia acetate, esetshenziswa ekucwengisiseni ama-syngas ukususa i-litl CO ne-CO2
6. Isithombe: Unjiniyela
7. Irabha yemvelo: I-Coagulant
8. Imboni yezokwakha: Ukuvimbela ukhonkolo ekushiseni9. I-Addtin ibuye isetshenziswe kabanzi ekwelapheni amanzi, i-syntheticfiber, izibulala-zinambuzane, amapulasitiki, isikhumba, upende, ukucubungula insimbi kanye nemboni yenjoloba.
I-Huanghua Pengfa Chemical Co., Ltd. yasungulwa ngo-1988, ngaphambili eyayaziwa ngokuthi i-Huanghua Pengfa Chemical Factory. ukuzivumelanisa nokuthuthukiswa kwezimakethe. Ekuqaleni kuka-2013, yaqanjwa kabusha ngokuthi i-Huanghua Pengfa Chemical Co., Ltd. Le nkampani iyinkampani yokukhiqiza, yokuthengisa nokuthekelisa. Imikhiqizo ihlanganisa i-acetic acid, i-sodium acetate, i-glacial acetic acid, i-formic acid, ukudaya i-acetic acid, i-sodium formate, i-calcium formate, i-carbon composite, i-super carbon nezinye izinto zokusetshenziswa zamakhemikhali. Inkampani inomlando weminyaka engaphezu kwengama-30, sizimisele ngokuba ngochwepheshe.
Okuphakelayo grade calcium formate;
1. Njengohlobo olusha lwesithasiselo sokuphakelayo. Ukondla i-calcium formate ukuze ukhule isisindo kanye nokusebenzisa i-calcium formate njengesithako sokuphakela amazinyane engulube kungakhuthaza ukulangazelela ukudla kwezingulube futhi kunciphise izinga lohudo. Ukwengeza u-1% kuya ku-1.5% we-calcium formate ekudleni kwezingulube kungathuthukisa kakhulu ukusebenza kwezingulube ezilunyuliwe. Ucwaningo lwaseJalimane lwathola ukuthi ukwengeza u-1.3% we-calcium formate ekudleni kwezingulube ezilunyuliwe kungathuthukisa izinga lokuguqulwa kokuphakelayo ngo-7% kuya ku-8%, futhi ukwengeza u-0.9% kunganciphisa ukutholakala kwesifo sohudo. UZheng Jianhua (1994) wengeze i-calcium formate engu-1.5% ekudleni kwezingulube ezilunyuliwe ezinezinsuku ezingama-28 izinsuku ezingama-25, inzuzo yansuku zonke yamaphuphu inyuke ngo-7.3%, izinga lokuguqulwa kokudla kwenyuka ngo-2.53%, kanye namaprotheni kanye amazinga okusetshenziswa kwamandla anyuswe ngo-10.3%. 9.8%, isifo sohudo sezingulube sehliswe kakhulu. UWu Tianxing (2002) wengeze i-calcium formate engu-1% ekudleni kwengulube eyi-ternary hybrid weaned, inzuzo yansuku zonke yenyuka ngo-3%, izinga lokuguqulwa kokuphakelayo lenyuke ngo-9%, kanti izinga lohudo lwengulube lehla ngo-45.7%. Ezinye izinto okufanele uziqaphele yilezi: kuyaphumelela ukusebenzisa i-calcium formate ngaphambi nangemva kokulunyulwa, ngoba i-hydrochloric acid ekhishwa amazinyane engulube iyanda ngokukhula; i-calcium formate iqukethe ama-30% e-calcium emuncwa kalula, ngakho-ke qaphela ukulungisa i-calcium ne-phosphorus lapho wenza ukudla. ,ingxenye.
