Span 80, kemikari inozivikanwa se sorbitan monoleate, ndeye nonionic surfactant uye inoshandiswa zvakanyanya muminda yakadai sechikafu, mishonga, zvizorwa uye indasitiri.
Indasitiri yechikafu: Span 80 ine yakanakisa emulsifying zvivakwa, izvo zvinogona kusanganisa mafuta nemvura, kudzivirira kupatsanurwa kwemafuta nemvura muchikafu, uye kugadzirisa kugadzikana uye kuravira kwechikafu. Nokudaro, inoshandiswa zvakanyanya se emulsifier. Inogona kushandiswa mukugadzirwa kwezvokudya zvakadai semajarini, zvigadzirwa zvemukaka, chokoreti uye zvinwiwa.
Indasitiri yezvizoro: Span 80 ine yakanakisa emulsifying, kuparadzira uye solubilizing zvivakwa. Mune cosmetics, inowanzoshandiswa se emulsifier mukugadzirwa kwemafuta, lotions uye zvimwe zvigadzirwa. Inogona kusanganisa kusanganisa chikamu chemafuta uye chikamu chemvura kuti iite yakagadzikana emulsion system. Panguva imwecheteyo, inewo imwe nzira yekunyorovesa, iyo inobatsira kuchengetedza unyoro hweganda uye kuita kuti ganda rive rakapfava uye rakanaka.
Muindasitiri yemishonga, Span 80 inonyanya kushandiswa semulsifier, solubilizer uye dispersant. Inogona kushandiswa kugadzira mafomu emushonga akadai semulsions uye liposomes, kuvandudza kugadzikana uye bioavailability yemishonga.
Indasitiri yemachira: Span 80 inogona kushandiswa seyekuwedzera machira uye ine mabasa akadai sekupfavisa, kutsetseka uye anti-static. Inogona kuderedza friction coefficient pakati pe fiber, ichipa machira kupfava ruoko kunzwa uye kupenya kwakanaka. Panguva imwecheteyo, inogona zvakare kuderedza kugadzirwa kwemagetsi static, kuvandudza kunaka uye kugadzirisa kushanda kwemachira.
Coatings neingi indasitiri: Span 80 inogona kushandiswa se dispersant uye emulsifier. Mune machira, inogona kuparadzira zvakaenzana pigment mubhesi repende, kudzivirira pigment sedimentation uye caking, uye kuwedzera simba rekuvhara uye kugadzikana kwejasi. Muinki, Span 80 inobatsira emulsify uye kuparadzira inki, zvichiita kuti ifambiswe zviri nani uye inonamira kune inodhinda panguva yekudhinda, nekudaro ichiwedzera kunaka kwekudhinda.
Indasitiri yePurasitiki: Span 80 inogona kushandiswa seantistatic agent uye lubricant yemapurasitiki. Inogona kuumba firimu rinoita pamusoro pepurasitiki, kuburitsa static magetsi, kudzivirira iyo yepurasitiki pamusoro kubva pakushambadza huruva uye kusvibiswa nekuda kwekuunganidzwa kwemagetsi static, uye panguva imwechete inonatsiridza mashandiro epurasitiki, kuderedza kupokana panguva yekugadzira, uye kuwedzera kugadzirwa kwakanaka uye kunaka kwechigadzirwa.
Mumunda wekurima, Sipan 80 inogona kushandiswa sekuwedzera kune emulsifiers emushonga wezvipembenene uye zvimiro zvekukura kwezvirimwa. Senge emulsifier yemishonga yezvipembenene, inogona kuparadzira zvakaenzana zvinhu zvinoshanda mumishonga yezvipembenene mumvura, ichigadzira emulsion yakagadzikana, nekudaro ichiwedzera kushanda kwekushandisa uye kuchengetedzwa kwemishonga yezvipembenene. Sechimwe chekuwedzera kune zvinomera zvinokura zvigadziriso, Span 80 inogona kubatsira zvinomera kukura kwezvirimwa kupinda zviri nani mumuviri wechirimwa uye kuwedzera kushanda kwavo.
