Ndi sodium formate: kupanga katundu ndi ntchito

Pali mankhwala ambiri kuti moyo mosavuta kwa munthu wamakono. Umodzi mwa imeneyi ndi sodium formate. Chilinganizo pawiri ichi - HCOONa. Amagwiritsidwanso zambiri amatchedwa formate ndi sodium.

mwachidule

Sodium formate ndi byproduct opangidwa pa ulimi wa pentaerythritol. Nkhanizi ambiri amangoti ntchito ngati wothandizira kuchepetsa mu zochita organic kaphatikizidwe. Kukonzekera formate ndi sodium amagwirizana ndi mavuto ena mu kuyeretsedwa pawiri izi. Choncho, mu mankhwala kumapeto nthawi zonse kusakanizikana pang'ono pentaerythritol ndi ena ofanana. Sodium formate - ndi crystalline ufa, woyera kapena pang'ono grayish mtundu. Nthawi zina malonda akukumana ndi sodium formate ndi pang'ono Kamaoneka kulocha. Zosafunika pano mu izo zosaoneka ndi apoyera. Ufa, amene akugulitsa, kachigawo misa zinthu zofunika ayenera kukhala osachepera 92%. Qualitatively, sodium formate kulemera yeniyeni ya madzi sayenera upambana 3%. Mu mankhwala ndi ndi sweeteners. Kumbali ya zili shuga sangathe upambana 1%.

Pakali pano, palibe umodzi mafakitale kupanga za mankhwala izi. Popeza formate ndi sodium amapangidwa pamene chochokera, pamafunika zina zapadera luso processing. Makampani ena amayesa kuti lithe mankhwala, koma kupanga amenewa ndi okwera mtengo kwambiri ndipo si oyenera kuŵeta.

Dongosolo la formate ndi sodium - HCOONa. Popeza nkhaniyi lili asidi formic zomwe kwambiri protivolednym reagent nthawi zambiri kwambiri ntchito ngati zoletsa kuwuma kwa.

Katundu wa formate ndi sodium

Chopangidwa luso ndi sodium formate ntchito m'mafakitale angapo. ntchito zake ambiri chifukwa katundu. mankhwala ndi sungunuka kwambiri madzi. Ndi pang'ono sungunuka mu mowa ndi insoluble efa. Sodium formate si kuunikiridwa ndi kwathunthu kuphulika-umboni. Ngakhale, mu malo osungira ndi ntchito sangathe ntchito lawi poyera ndi kusuta akuletsedwa.

Madera a ntchito mankhwala a

Izo ntchito monga zoletsa kuwuma zowonjezera kupanga zosiyanasiyana nyumba nyumbayi. Amagwiritsidwanso ntchito mu makampani khungu. Izo ntchito maopaleshoni osiyanasiyana preddubilnyh.

The formate ndi sodium monga zopangira ndi yofunika kupanga zinthu zina mankhwala monga asidi formic. Amagwiritsidwanso ntchito mu makampani mafuta ndi monga zikuluzikulu za wothandizila odana icing.

Amene amadza pa thupi la munthu

Sodium formate mu digiri awo kukhudzana anthu otchulidwa 4 kalasi ya ngozi. Zingayambitse mavuto aakulu kwa thupi woipa mkulu. Sodium formate zimayambitsa kuyabwa kwa nembanemba mucous ndi kapepala chapamwamba kupuma. Pokambirana ndi mankhwala uyu ayenera kugwiritsidwa ntchito PPE: makina, chowala, magolovesi. Mu nkhani ya ngozi ndi kutulutsidwa kwa yambiri formate ndi sodium chofunika ntchito mpweya chigoba. Pakuti kusungiramo youma mankhwala okonzeka malo akutali, kumene kusungidwa mu matumba pa pallets wapadera.

Sodium formate - zoletsa kuwuma

Kuwonjezera ntchito mafakitale ndi kumanga, mankhwala amagwira ntchito ngati wothandizira zoletsa kuwuma ndi yosalekerera kwenikweni. Iye, mosiyana ndi zina wothandizila odana icing, alibe amadza zoopsa pa chilengedwe. Komanso, kuchokera si kwambiri anakhudzidwa zitsulo mbali ya galimoto. Ake ufulu ndi angagwiritsidwe ntchito pa matenda a nyumba zopangidwa pa ofesi ya msewu ngati woletsa dzimbiri.

Sodium formate Yomanga

mankhwala Ichi ndi chofunika kwambiri yomanga konkire monolithic ndipo anatsindika nyumba konkire mu nyengo yozizira. Komanso tikulimbikitsidwa kuti ntchito ngakhale pamene mpweya kutentha - 5 ° C. Amagwiritsidwanso ntchito mu yopanga monoliths mu nyumba precast kuti anatsekera mafupa, chifukwa precast mankhwala konkire. Sodium formate anadzetsa osakaniza konkire mu kufanana zotsatirazi:

• 2% mwa kulemera kwa simenti ntchito mawu a mankhwala ouma ndi anaumitsa pa kutentha kwa -5 ° C (mlingo wa makilogalamu 8 / L 7);

• 3% - kwa -10 ° C (makilogalamu 12 / 10.5 L);

• 4% - kwa -15 ° C (16 makilogalamu / 14 L).

Pa yokonza simenti ndi formate ndi sodium kusungunuka m'madzi ofunda. Pankhaniyi pali umboni wapadera wosakanizira njira. Kotero, anawonjezera pamodzi ndi madzi kuphatikiza kudzera wapadera zina dispenser mankhwala. Mukhozanso ntchito dispenser madzi. Zikatero, kusanganikirana m'pofunika kuchepetsa mowa wake ndi 8-13%. Chifukwa formate ndi sodium ndi mathamangitsidwe wa oipa konkire, umene uli makamaka zogwirizana pa ntchito yomanga nyumba mkulu-nyamuka.

kusamala

Nkhanizi sangathe ntchito mu zomangamanga chisanadze anatsindika, pamene zitsulo ntchito ikuthandizira makalasi AT-VI, AT-IV, A-V. Komanso, si oyenera konkire ndi konkire mankhwala zigwiritsidwe ntchito pa mapangidwe mpweya ndi madzi ndi chinyezi kuposa 60% ndi zomangamanga cholinga malonda mafakitale ndi zoyendera inasangalatsa, kumene DC ntchito.

Pamene ntchito nkhaniyi tiyenera kukumbukira kuti akadali si "gostirovano" monga zoletsa kuwuma, kotero yekha ntchito zokhudza izo, umene uli ankalamulira ndi "Malangizo pa ntchito ndi sodium formate luso". Yotsirizira anali wavomerezedwa ndi komiti Katswiri wa sayansi ndi luso Council NIISK. opanga zambiri za mankhwala anamasulidwa ndi ake specifications luso (Lachiwiri). Pakali pano, ndi kugulitsa katundu opezeka China, n'zosatheka kutsimikizira kuti khalidwe chabe nthawi zilibe ngakhale zikalata za. N'chifukwa chake ndi bwino kugula zinthu kwa alimi odalirika zoweta.
