Iphepha leDatha lobuGcisa iPolyether Amine LHD-123
I-polyether amines luhlobo lwe-diamines kunye namaqela e-amino ekupheleni kunye nobunzima bemolekyuli ezahlukeneyo ze-polyepoxypropane / i-ethylene oxide njengeyona nto ingundoqo yekhonkco.Ikhonkco eliphambili le-LHD123 liqela le-polyepichlorohydrin, kunye namaqela amabini aphambili e-amine kuzo zombini iziphelo zekhonkco, kunye ne-avareji ye-molecular weight malunga ne-230.
I-epoxy yokunyanga i-anent;
Iphendula kunye ne-carboxylic acid yenze izinto zokuncamathelisa ezinyibilikayo ezishushu.
| Into | Umgangatho |
| Umbala, APHA | ≤25 |
| Ukufuma,% | ≤0.25 |
| Ixabiso le-amine,mmol/g | 8.1-8.7 |
| I-Amine yokuqala,% | ≥97 |
| Imbonakalo | Ulwelo olungenambala ukuya kolutyheli olucacileyo |
Isingxobo sokupakisha semveliso ye-amino ephelisiwe yepolyether yipeyinti ecocekileyo neyomisiweyo eqatywe igubu lentsimbi elingaphakathi.Isiciko sesikhongozeli sokupakisha kufuneka sitywinwe ngokungqongqo kwaye sibe nesigqubuthelo sangaphandle.Isiqulatho esinetha kwigubu ngalinye lemveliso epakishiweyo yi-200kg, kwaye ezinye iintlobo zezingxobo zokupakisha ezicocekileyo nazo zingasetyenziswa.Ibhetshi nganye yeemveliso kufuneka ikhatshwe sisiqinisekiso somgangatho.
Iipolyether ze-amino eziphelisiwe ziikhemikhali ezingenabungozi.Ngexesha lokuthutha, imvula kunye nokungcola kufuneka kuthintelwe, kwaye kufuneka kuphathwe ngononophelo ukuthintela ukungqubana nezinto ezinzima kunye nokuvuza.
Iimveliso zepolyether ezipheliswe i-amino kufuneka zigcinwe kwindawo engena umoya, eyomileyo, nepholileyo.Imveliso kufuneka igcinwe unyaka omnye ukususela kumhla wemveliso phantsi kokupakishwa, ukuthutha, kunye neemeko zokugcina ezichazwe kweli candelo.
1.Ndingayikhetha njani ipolyol efanelekileyo kwiimveliso zam?
A: Unokubhekisela kwi-TDS, ukuqaliswa kwesicelo semveliso yeepolyols zethu.Unokuqhagamshelana nathi ngenkxaso yobugcisa, siya kukunceda ukuba ufanise i-polyol ehambelana neemfuno zakho.
2.Ndingayifumana isampuli yovavanyo?
A: Siyavuya ukunika isampuli kuvavanyo lwabathengi.Nceda uqhagamshelane nathi ngeesampulu ze-polyols onomdla kuzo.
3.Lide kangakanani ixesha lokukhokela?
A: Umthamo wethu ohamba phambili wokuvelisa iimveliso zepolol e-China yenza ukuba sihambise imveliso ngokukhawuleza kwaye ngendlela ezinzileyo.
4.Singakwazi ukukhetha ukupakisha?
A: Sinikezela ngendlela eguquguqukayo kunye neendlela ezininzi zokupakisha ukuhlangabezana neemfuno ezahlukeneyo zabathengi.
