Umgomo kanye nezinzuzo ze-magnesium hydroxide flame retardant
I-Magnesium hydroxide iyi-inorganic flame retardant filler, enethuba elibanzi lokusebenza ezintweni eziyinhlanganisela esekwe ku-polymer.I-Magnesium hydroxide flame retardant iyabola futhi ikhiphe amanzi lapho ifudunyezwa, imunca ukushisa, yehlisa izinga lokushisa lomlilo ebusweni be-polymer material, futhi ibambezele inqubo yokuwohloka kwe-polymer ibe isisindo esiphansi samangqamuzana.Ngesikhathi esifanayo, umhwamuko wamanzi okhululiwe unganciphisa umoya-mpilo phezu kwezinto ezibonakalayo, uvimbele ukushiswa kwezinto ezibonakalayo.Ngakho-ke, i-magnesium hydroxide flame retardant inezinzuzo zokungewona ubuthi, intuthu ephansi, futhi akukho ukungcoliswa kwesibili.Kuyinto evimbela ilangabi elivumela imvelo.
Isidingo sokushintsha i-magnesium hydroxide
Kodwa-ke, uma kuqhathaniswa ne-halogen-based flame retardants, i-magnesium hydroxide flame retardants idinga inani eliphezulu lokugcwalisa ukuze kuzuzwe umphumela ofanayo wokubuyisela ilangabi, ngokuvamile ngaphezu kwama-50%.Ngenxa yokuthi i-magnesium hydroxide iyinto engaphili, ayihambisani kahle nezinto ezisekelwe ku-polymer.Inani eliphakeme lokugcwalisa lizothinta izakhiwo zemishini yezinto ezihlanganisiwe.Ukuze uxazulule le nkinga, kuyadingeka ukuguqula ubuso be-magnesium hydroxide ukuze kuthuthukiswe ukuhambisana kwayo nezinto ezisekelwe ku-polymer, ukuthuthukisa ukuhlakazeka kwayo ezintweni ezihlanganisiwe, ukwandisa umsebenzi wayo ongaphezulu, ngaleyo ndlela kuncishiswe umthamo wayo, kuthuthukise ukusebenza kahle kwayo kokunciphisa ilangabi, nokugcina. noma ukuthuthukisa izakhiwo zemishini zezinto eziyinhlanganisela.
Izindlela zokushintsha i-magnesium hydroxide
Njengamanje, kunezindlela ezimbili ezivamile zokushintsha i-magnesium hydroxide: indlela eyomile kanye nendlela emanzi.Ukuguqulwa kwendlela eyomile ukuxuba i-magnesium hydroxide eyomile nenani elifanele le-solvent engasebenzi, ukuyifutha nge-coupling agent noma enye i-ejenti yokwelapha engaphezulu, bese uyixuba emshinini wokuxova onesivinini esiphansi ukuze uthole ukwelashwa kokuguqulwa.Ukuguqulwa kwendlela emanzi ukumisa i-magnesium hydroxide emanzini noma kwezinye izincibilikisi, wengeze ngokuqondile i-ejenti yokwelapha engaphezulu noma i-disperant, bese uyishintsha ngaphansi kokunyakaziswa.Lezi zindlela ezimbili zinezinzuzo kanye nezinkinga zazo futhi zidinga ukukhethwa ngokuvumelana nezimo ezithile.Ngaphezu kwendlela yokuguqula indawo, indlela yokucwenga ingasetshenziswa futhi ukuchoboza i-magnesium hydroxide powder ezingeni le-nanometer, kwandiswe indawo yayo yokuxhumana ne-polymer matrix, ithuthukise ukuhlobana kwayo ne-polymer, futhi ngaleyo ndlela ithuthukise umphumela wayo wokunqanda ilangabi.
