Span 80, inozivikanwa nemakemikari sesorbitan monoleate, imushonga usiri weionic surfactant uye inoshandiswa zvakanyanya muminda yakaita seyekudya, mishonga, zvizoro uye maindasitiri.
Indasitiri yezvekudya: Span 80 ine hunhu hwakanaka hwe emulsifying, iyo inogona kusanganisa mafuta nemvura zvakaenzana, kudzivirira kupatsanurwa kwemafuta nemvura muchikafu, uye kunatsiridza kugadzikana uye kuravira kwechikafu. Saka, inoshandiswa zvakanyanya se emulsifier. Inogona kushandiswa mukugadzira zvekudya zvakaita semargarine, zvigadzirwa zvemukaka, chokoreti nezvinwiwa.
Indasitiri yezvizoro: Span 80 ine hunhu hwakanaka hwe emulsifying, disaspersing uye surlubilizing. Muzvizoro, inowanzoshandiswa se emulsifier mukugadzira makirimu, lotions nezvimwe zvigadzirwa. Inogona kusanganisa zvakaenzana chikamu chemafuta nechikamu chemvura kuti igadzire emulsion system yakagadzikana. Panguva imwe chete, inewo hunyoro hwakati, hunobatsira kuchengetedza hunyoro hweganda uye kuita kuti ganda rive rakapfava uye rakatsetseka.
Muindasitiri yemishonga, Span 80 inonyanya kushandiswa semushonga unosanganisa mishonga, unonyungudutsa uye unonyungudutsa. Inogona kushandiswa kugadzira mhando dzemushonga dzakadai semushonga unonyungudutsa mishonga uye mafuta anonyungudutsa mishonga, zvichivandudza kugadzikana uye kuwanikwa kwemishonga.
Indasitiri yemachira: Span 80 inogona kushandiswa sekuwedzera kwemachira uye ine mabasa akadai sekupfavisa, kupfavisa uye kurwisa kusagadzikana. Inogona kuderedza kukweshana pakati pemachira, zvichiita kuti machira anzwe akapfava uye kupenya kwakanaka. Panguva imwe chete, inogonawo kuderedza kugadzirwa kwemagetsi asingachinji, ichivandudza mhando uye mashandiro emachira.
Indasitiri yeCoatings neInk: Span 80 inogona kushandiswa sedispersant uye emulsifier. MuCoatings, inogona kuparadzira pigments zvakaenzana mupendi, kudzivirira kudonha kwepigment uye kuchekwa, uye kuwedzera simba rekufukidza uye kugadzikana kweCoatings. MuInk, Span 80 inobatsira emulsifying uye kuparadzira inki, zvichiita kuti ikwanise kutamiswa zviri nani uye kunamatirwa kune zvinhu zvinodhindwa panguva yekudhinda, nokudaro ichivandudza kunaka kwekudhinda.
Indasitiri yepurasitiki: Span 80 inogona kushandiswa semushonga unodzivirira static uye semafuta epurasitiki. Inogona kugadzira firimu rinofambisa mvura pamusoro pepurasitiki, kuburitsa magetsi asingachinji, kudzivirira pamusoro pepurasitiki kuti isasvetuke guruva netsvina nekuda kwekuungana kwemagetsi asingachinji, uye panguva imwe chete inovandudza mashandiro epurasitiki, kuderedza kukweshana panguva yekugadzirisa, uye kuwedzera kushanda zvakanaka kwekugadzira uye kunaka kwechigadzirwa.
Mumunda wekurima, Sipan 80 inogona kushandiswa sechinhu chinowedzera mishonga inouraya zvipembenene uye chinodzora kukura kwezvirimwa. Sechinhu chinoderedza mishonga inouraya zvipembenene, inogona kuparadzira zvakaenzana zvinhu zvinoshanda zviri mumvura, zvichiita kuti ive emulsion yakasimba, nokudaro ichivandudza kushanda kwayo uye kuchengetedzeka kwemishonga inouraya zvipembenene. Sechinhu chinowedzera mishonga inouraya zvirimwa, Span 80 inogona kubatsira zvinodzora kukura kwezvirimwa kupinda zviri nani mumuviri wezvirimwa uye kuwedzera kushanda kwayo.
