CAS 461-58-5 dicyandiamide ifu ya kirisiti ya kirisiti 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.

Imiterere yimiti

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:

Kugena cobalt, nikel, umuringa na palladium. Synthesis ya Organic.Nitrocellulose stabilisateur.Umuyobozi mukuru.

Ikoreshwa nkibintu byihishe bikiza bya epoxy resin yifata.Guhindura igice kimwe cya epoxy yifata.Gusa iyo ingano yingirakamaro ya dicyandiamide iri munsi cyangwa ingana na 5μm (mesh 2500), irashobora gukora ihagarikwa muri resinike ya epoxy idafite imvura. dosiye ikoreshwa ni 4-12, kandi ubuzima bwakoreshejwe bwa 100g epoxy resin yibigize ni amezi 6-12.Iyo dosiye ya dicyandiamide ari 17, igihe cyo kubika ntikiri munsi yamezi 2. Iyo dosiye ari 8, kubika igihe gishobora kuba kingana nigice cyumwaka. Ibihe byo gukiza170 ℃ / lh cyangwa 180 ℃ / 20min. Ubushyuhe bwo kugoreka ubushyuhe 125 ℃ .Ikindi kandi gikoreshwa nkumuti ukiza ibice bimwe byamazi ya epoxy yamazi.Ibipimo byerekana ni 7. Serivisi. ya dicyandiamide (ibice 5-6) na hydrazide (ibice 3-4), Irashobora gukiza epoxy resin kuri 120 ℃ / 45min.

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 zipakurura. Umunwa wumufuka ugomba gufungwa cyane kandi ntugomba kumeneka.Uburemere bwa net ni 25 ± 0.2kg kumufuka.
