Span-80 ni amavuta yumuhondo. Ihita ishonga mumazi, Ethanol, methanol cyangwa acetate ya Ethyl, kandi igashonga gato mumavuta yubutare. Nubwoko bwa aw / o emulsifier, ifite imbaraga zikomeye zo gukwirakwiza, gutatanya no gusiga amavuta. Irashobora kuvangwa na surfactants zitandukanye, cyane cyane ikwiriye gukoreshwa na Tween -60, kandi ingaruka niyo nziza iyo ikoreshejwe hamwe. Agaciro ka HLB ni 4.7 naho gushonga ni 52-57 ℃.

Span 80, imiti izwi nka sorbitan monoleate, ni surfactant idasanzwe kandi ikoreshwa cyane mubice nkibiryo, ubuvuzi, amavuta yo kwisiga n'inganda.
Inganda zikora ibiryo: Span 80 ifite emulisitiya nziza cyane, ishobora kuvanga amavuta namazi, bikarinda gutandukanya amavuta namazi mubiribwa, kandi bikazamura ituze nuburyohe bwibiryo. Kubwibyo, ikoreshwa cyane nka emulifier. Irashobora gukoreshwa mugukora ibiryo nka margarine, ibikomoka ku mata, shokora hamwe n'ibinyobwa.
Inganda zo kwisiga: Span 80 ifite emulisile nziza, ikwirakwiza kandi ikanabishisha. Mu kwisiga, akenshi bikoreshwa nka emulifisiyeri mugukora amavuta, amavuta yo kwisiga nibindi bicuruzwa. Irashobora kuvanga neza icyiciro cyamavuta nicyiciro cyamazi kugirango ikore sisitemu ihamye. Muri icyo gihe, ifite kandi ingaruka zimwe na zimwe zitanga amazi, zifasha kugumana ubushuhe bwuruhu no gutuma uruhu rworoha kandi rworoshye.
Mu nganda zimiti, Span 80 ikoreshwa cyane nka emulisiferi, solubilizer na dispersant. Irashobora gukoreshwa mugutegura imiti yimiti nka emulsiyo na liposomes, kunoza ituze hamwe na bioavailable yibiyobyabwenge.
Inganda z’imyenda: Span 80 irashobora gukoreshwa nkinyongera yimyenda kandi ifite imirimo nko koroshya, koroshya no kurwanya static. Irashobora kugabanya coefficente yo guterana hagati ya fibre, igaha imyenda ukuboko kworoshye kumva no kurabagirana. Muri icyo gihe, irashobora kandi kugabanya kubyara amashanyarazi ahamye, kuzamura ubuziranenge no gutunganya imyenda.
Inganda hamwe na wino inganda: Span 80 irashobora gukoreshwa nka dispersant na emulsifier. Mu gutwikira, irashobora gukwirakwiza neza pigment mu marangi, ikarinda imyanda ya pigment na cake, kandi ikongerera imbaraga zo gupfuka no guhagarara neza. Muri wino, Span 80 ifasha kwigana no gukwirakwiza wino, bigatuma ishobora kwimurwa neza no gufatirwa mubikoresho byo gucapa mugihe cyo gucapa, bityo bikazamura ubwiza bwo gucapa.
Inganda za plastiki: Span 80 irashobora gukoreshwa nka antistatic anticatic and lubricant for plastique. Irashobora gukora firime ikora hejuru ya plastike, ikarekura amashanyarazi ahamye, ikabuza ubuso bwa plastike kwangiza umukungugu n’umwanda bitewe n’ikwirakwizwa ry’amashanyarazi ahamye, kandi icyarimwe bigateza imbere imikorere y’itunganywa rya pulasitike, bikagabanya ubushyamirane mu gihe cyo gutunganya, kandi bikongera umusaruro n’ubwiza bw’ibicuruzwa.
Mu murima wubuhinzi, Sipan 80 irashobora gukoreshwa nkinyongera kumiti yica udukoko twangiza udukoko twangiza imiti. Nka emulisiferi yimiti yica udukoko, irashobora gukwirakwiza ibintu byingirakamaro mumiti yica udukoko mumazi, bigakora emulisiyo ihamye, bityo bikazamura ingaruka zikoreshwa numutekano wica udukoko. Nka nyongera kubashinzwe gukura kw'ibimera, Span 80 irashobora gufasha kugenzura imikurire y'ibihingwa kwinjira neza mumubiri wibimera no kuzamura imikorere yabyo.
