Ama-Polyamineimelela uhlobo lwamakhemikhali e-organic olubonakala ngokuba khona kwamaqembu amaningi ama-amino. Lawa makhemikhali, ngokuvamile ayisisombululo esingenambala, esijiyile emazingeni acishe angathathi hlangothi e-pH. Ngokufaka ama-amine noma ama-polyamine ahlukene ngesikhathi sokukhiqizwa, imikhiqizo ye-polyamine enesisindo sama-molecule ahlukene kanye namazinga okuhlanganisa ingatholakala ukuze ivumelane nezinkambu ezahlukene zokwelashwa kwamanzi.
Ngakho-ke, ukusetshenziswa kwama-polyamines kuhlanganisa izimboni ezahlukene, okuhlanganisa ukucaciswa kwamanzi, ukuhlukaniswa kwamafutha namanzi, ukususwa kombala, ukwelashwa kwemfucuza, kanye nokujiya kwe-latex ezitshalweni zerabha. Lawa ma-compounds aphinde abe usizo embonini yokumboza kanye nephepha, kanye nasezinhlelweni ezahlukahlukene njengokwelashwa kwemfucuza yokucubungula inyama, njengasemfucumfucwini yezitshalo zenkukhu. Ama-polyamine atholakala ngamagremu amaningi, kanye nokugxila okuqinile okusukela ku-50 kuya ku-60%.
Ama-polyamine ahamba phambili ekuhlanganiseni ukusabalala kwe-colloidal, ikakhulukazi ekusetshenzisweni kokulawula idiphozithi mayelana ne-pulp, isitokwe, izintambo, noma ama-felt. Asusa ngempumelelo izinto eziphilayo kanye nombala emifudlaneni ejikelezayo noma ephumayo emishinini yokugaya kanye nephepha. Kodwa-ke, ukukhetha umkhiqizo we-polyamine ongabizi kakhulu kudinga ukuhlolwa kokusebenza okwenzelwe ukudla okuthile noma umfudlana ohloselwe ukwelashwa. Ama-polyamine anganikezwa kahle noma ahlanjululwe emgqeni endaweni yokwelashwa.
Izidingo zomthamo wama-polyamine zincike ebunzimeni benkinga ekhona. Ukuze kulawulwe idiphozithi ku-pulp noma esitokweni, umthamo uvame ukusuka ku-0.25 kuya ku-2.5 kg we-polyamine ngethani le-pulp noma isitokweni (isisekelo esomile). Uma kuxazululwa izinkinga zediphozithi endwangwini yokwakha, umthamo onconywayo usukela ku-0.10 kuya ku-1.0 milliliters ngomzuzu ngonyawo lobubanzi bendwangu.
Ukugcinwa nokuphathwa kahle kwama-polyamine kubaluleke kakhulu ukuze kugcinwe ukusebenza kwawo kahle. Ama-polyamine kufanele agcinwe ngaphakathi kwezinga lokushisa elingu-10–32°C. Ukuchayeka isikhathi esifushane emazingeni okushisa angaphandle kwalolu hlobo ngokuvamile akulimazi umkhiqizo. Uma eqandisiwe, ama-polyamine kufanele afudunyezwe abe ngu-26–37°C futhi axutshwe kahle ngaphambi kokusetshenziswa. Isikhathi sokuphila sama-polyamine ngokuvamile sifinyelela ezinyangeni ezingu-12.
Ezisetshenzisweni ezisebenzayo, inhlanganisela yeI-Polyamine FlocculantI-s ene-PAC (i-polyaluminum chloride) ibonise ukusebenza kahle kokususa ukungcola ezinqubweni zokwelashwa kwamanzi. Inhlanganisela ye-PAC/polyamine inciphisa ngempumelelo umthamo we-PAC, yehlisa ukugcwala kwama-ion e-aluminium asele emanzini aphathwe, futhi ithuthukisa ukususwa kokungcola.
Ngesikhathi sokugcina, ama-polyamine kufanele agcinwe ezitsheni zawo zokuqala ezinezimbobo zomoya, kude nokushisa, ilanga eliqondile. Ukuze uthole imiyalelo eningiliziwe yokuphatha kanye nezinyathelo zokuphepha, abasebenzisi kufanele babheke ilebula lomkhiqizo kanye ne-Safety Data Sheet (SDS).
Singochwephesheumhlinzeki wama-polyamineyokwelapha ezimbonini. I-polyamine ethengiswayo enkampanini yethu ingasebenza kahle isikhathi eside! Xhumana nathi! ( I-imeyili:sales@yuncangchemical.com )
