Izinzuzo ze-Magnesium Hydroxide Flame Retardant

I-Magnesium hydroxide uhlobo lwendabuko lwesithambisi somlilo esisekelwe ku-filler. Uma sibekwe ekushiseni, siyabola futhi sikhiphe amanzi aboshwe, simunce inani elikhulu lokushisa okucashile. Lokhu kunciphisa izinga lokushisa lobuso bezinto ezihlanganisiwe emalangabini, kuvimbele ukubola kwe-polymer futhi kupholise amagesi avuthayo akhiqizwayo. I-Magnesium hydroxide iyisithambisi esithembisayo esivimbela ilangabi esingenazinto eziphilayo sezinto ezihlanganisiwe ezisekelwe ku-polymer. Njenge-aluminium hydroxide, isebenza ngokumunca ukushisa ngokubola kokushisa nokukhulula amanzi, okwenza kungabi yingozi, kungabi nentuthu eningi, futhi kube nobungane nemvelo, njengoba i-magnesium oxide ephumelayo izinzile futhi ayibangeli ukungcola kwesibili.

Kodwa-ke, uma kuqhathaniswa nezithambisi zomlilo eziphilayo eziqukethe i-halogen, ukufeza umphumela ofanayo wokuvimbela umlilo kudinga isilinganiso sokugcwalisa esingaphezu kuka-50%. Njengoba i-magnesium hydroxide ingeyona into ephilayo, ubuso bayo abuhambisani kahle nezithambisi ze-polymer. Isilinganiso sokugcwalisa esiphezulu kangaka, ngaphandle kokuguqulwa kobuso, sizolimaza izakhiwo zemishini zezinto ezihlanganisiwe. Ngakho-ke, ukuguqulwa kobuso kuyadingeka ukuze kuthuthukiswe ukuhambisana kwayo nezithambisi ze-polymer, kuqinisekiswe ukuthi izakhiwo zemishini zezinto ezigcwalisiwe aziphazamiseki—noma zithuthukiswe kwezinye izici.

Kuyo yonke inqubo yokuvimbela ilangabi, i-magnesium hydroxide ayikhiqizi izinto eziyingozi. Ngaphezu kwalokho, imikhiqizo yayo yokubola ingamunca inani elikhulu lamagesi anobuthi kanye nentuthu ekhiqizwa ukusha kwerabha, amapulasitiki, namanye ama-polymer. I-magnesium oxide esebenzayo iqhubeka nokumunca izinsalela ezincibilikisiwe ezishisiwe ngokuphelele, icisha ngokushesha amalangabi ngenkathi isusa umusi futhi ivimbele ukuvuza kokuncibilika. Iyisivikelo somlilo esingokwemvelo esingenabungozi emvelweni.

Njengamanje, i-aluminium hydroxide isetshenziswa kabanzi eShayina. Kodwa-ke, njengoba amazinga okushisa okucubungula i-polymer enyuka, i-aluminium hydroxide ivame ukubola, kunciphisa ukusebenza kwayo okubambezela ilangabi. Uma kuqhathaniswa, i-magnesium hydroxide inikeza izinzuzo ezilandelayo:

1. Izinga Lokushisa Eliphakeme Lokubola Kokushisa – I-Magnesium hydroxide iyabola ku-340°C, okuphakeme ngo-100°C kune-aluminium hydroxide. Lokhu kuvumela amazinga okushisa aphezulu okucubungula ipulasitiki, kuthuthukiswe ukusebenza kahle kokukhipha, kuthuthukiswe ukwenziwa kwepulasitiki, kuncishiswe isikhathi sokubumba, futhi kuqinisekiswe ukukhanya okuphezulu kwendawo enamaphutha ambalwa ngenkathi kugcinwa amandla aqinile okuhlubuka.
2. Usayizi Wezinhlayiyana Ofanayo Nokuhambisana Okuhle - Ukusatshalaliswa kwezinhlayiyana zayo ngokulinganayo kuqinisekisa ukuhambisana okungcono nezingxenye ezingaphansi komhlaba, kunciphisa umthelela ezimpahleni zemishini zomkhiqizo.
3. Ukwakheka Kwesithiyo Esivikelayo – Ngemva kokuphelelwa amanzi emzimbeni ngesikhathi sokusha, i-magnesium oxide ephumayo iyinto enamandla aphezulu, engashisi ukushisa esebenza njengesithiyo esivikelayo, ihlukanisa amalangabi namagesi anobuthi. I-magnesium hydroxide iphinde iqede amagesi ane-acidic (SO₂, NOx, CO₂) akhiqizwa ngesikhathi sokusha kwepulasitiki.
4. Ukusebenza Kahle Kokubola Nokunciphisa Intuthu - Ibonisa amandla aqinile okuvimbela ilangabi nokucindezela intuthu ngenkathi ingahlukumezi kakhulu imishini, ngaleyo ndlela yandisa isikhathi sokuphila komshini.
5. Isebenza Kahle – I-Magnesium hydroxide flame retardant iyintengo eyingxenye ye-aluminium hydroxide. Umthamo wayo wokugcwalisa ophezulu unciphisa kakhulu izindleko zokukhiqiza.
