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.

Nkibikoresho byumunyu wa guanidine na melamine

Umunyu utandukanye wa guanidine urashobora kubyara mugukora dicyandiamide hamwe na aside.Diamine yasimbuwe na melamine diamine yabonetse kubisubizo bya dicyandiamide na benzonitrile ni intera yo gutwikira, laminates hamwe nifu ya poro.

Ikoreshwa nkumukozi wo gutunganya irangi.

Dicyandiamide resin ikorwa na reaction ya dicyandiamide na formaldehyde irashobora gukoreshwa nkibikoresho byo gutunganya irangi.

Ifumbire ya Dicyandiamide

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.

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.
