CAS 461-58-5 99.7% ifu ya kirisiti yera ya dicyandiamide

Ibisobanuro bigufi:

Dicyandiamide

Ifu ya kirisiti yera.Ibishobora kuboneka mumazi ni 2,26% kuri 13 ° C, Ubushyuhe bukabije mumazi ashyushye.Iyo igisubizo cyamazi cyangirika buhoro buhoro kuri 80 ° C, gaze ya amoniya irabyara.Iyo ibishishwa muri Ethanol yuzuye (C2H5OH) na ether ni 13 ° C, yari 1.26% na 0.01% .Gukemuka muri ammonia yamazi, amazi ashyushye, Ethanol, hydrat hydrat, dimethylformamide, idashobora gushonga muri ether, idashonga muri benzene na chloroform.Ubucucike bufatika (d254) 1.40.Ingingo yo gushonga 209.5 ℃.Bihamye iyo byumye.Ntabwo yaka. Hasi uburozi, imiti yica hagati (imbeba, umunwa)> 4000mg / kg.Ikigereranyo ntarengwa cyemewe mu kirere ni 5mg / m³.

Gukoresha no kubika nkuko byasobanuwe ntibishobora kubora no kwirinda gukoraho na okiside.Ibishobora gukomera muri Ethanol yuzuye kuri 13 ° C ni 1.26% naho mumazi ni 2.26% .Byoroshye gushonga mumazi ashyushye, igisubizo cyamazi kizangirika buhoro buhoro kugirango gitange gaze ya amoniya iyo ubushyuhe buri hejuru ya 80 ° C.Iyo kristu ya dicyandiamide ishyutswe kugeza aho ishonga, izahita ishyuha cyane nyuma yo gushonga kugirango itange melamine, melamine, nibindi.

Gusaba:

Ifumbire mvaruganda ya Dicyandiamide irashobora kugenzura ibikorwa bya bagiteri ya nitrifingi.Gutegeka igipimo cy’ifumbire mvaruganda ya azote mu butaka, Kugabanya igihombo cya azote no kunoza ikoreshwa ry’ifumbire.

Nka chimique nziza hagati

Mubuvuzi, ikoreshwa mugukora nitrat ya guanidine, sulfonamide, nibindi..Bikoreshwa kandi mukubyara thiourea, stabilisateur ya nitrocellulose, umuvuduko wa rubber vulcanisation, ibyuma byuma byuma, ibyuma byuzuza uruhu, ibifata, nibindi .Imiti hagati ya 5-azacytosine irashobora kuboneka nigisubizo cya dicyandiamide na acide formic. Doping ya azote yibikoresho bya karubone nkisoko ya azote.

Tinteguza

Gupakira bigomba kuba byuzuye mugihe cyo gutwara, gupakira bigomba kuba bifite umutekano.Mu gihe cyo gutwara abantu, menya neza ko kontineri idatemba, gusenyuka, kugwa cyangwa kwangirika. Birabujijwe rwose kuvanga no gutwara hamwe na okiside, acide, alkalis, imiti iribwa , nibindi Mugihe cyubwikorezi, bigomba kurindwa kutagira izuba, imvura, nubushyuhe bwinshi. Ikinyabiziga kigomba gusukurwa neza nyuma yo gutwara.

Ubike mububiko bukonje, buhumeka.Komeza kure yumuriro nubushyuhe.Bigomba kubikwa bitandukanye na okiside, acide na alkalis kandi ntibigomba kuvangwa mububiko.Bujuje ibikoresho bitandukanye nubwinshi bwibikoresho byumuriro. Ahantu ho kubika hagomba gutangwa hamwe nibikoresho bikwiye birimo isuka.

Ipaki:20 kg / 50 kg / 100 kg kuri pp;

25 kg / impapuro-plastike yibikoresho byo murwego rwamashanyarazi.

Uburyo bwo kubika

Ububiko bufunze kuri 2 ℃ ~ 8 ℃, kubika ahantu hahumeka kandi humye, wirinda gukoraho izindi oxyde.Mu gihe cyo gutwara no gupakira, bigomba kurindwa ubushuhe kandi bigakorwa neza.
Gupakirwa mumufuka uboshye hamwe numufuka wimbere wa plastike cyangwa ibice 5 byububiko bwimpapuro zipakira. Umunwa wumufuka ugomba gufungwa cyane kandi ntugomba gutemba.
