Alkyl Polyether: Kemikari Inoshandiswa Pakugadzira Zvinhu Zvakasiyana-siyana-1
Minda mikuru yekushandisa
Muindasitiri yemakemikari, maalkyl polyethers anoshandiswa sezvinhu zvekugadzira mafoam epolyurethane, manamati, ma sealant, uye elastomers. Mafoam epolyurethane anoshandiswa zvakanyanya mufenicha, matiresi, zvigaro zvemotokari, uye zvinhu zvinodzivirira zvivakwa. Manamati epolyurethane nema sealant anoshandiswa mukubatanidza zvivakwa, mota, uye zvishandiso zvemagetsi.
Muindasitiri yemishonga, maalkyl polyethers anoshanda sezvinhu zvinosanganisa mishonga, zvichiwedzera kugadzikana kwayo uye kunyungudika kwayo. Anoshandiswawo kugadzira ma defoamers, ma surfactants, uye zvinhu zvinonyorovesa, zvinoshandiswa zvakanyanya mumuromo, mumhino, mumaziso, munzeve, uye mushampoo.
Mumaindasitiri emachira nemapepa, ma alkyl polyether anoshandiswa sezvinhu zvinopfavisa, zvinodzivirira kushanduka kwechinhu, uye zvinonyorovesa. Anovandudza kupfava uye hunhu hwemachira hunodzivirira kushanduka kwechinhu uye anowedzera kunaka kwepepa uye kushanda zvakanaka mukugadzira mapepa.
Muzvikamu zvezvishandiso zvekuchenesa nekuchengetedza muviri, maalkyl polyethers anoshandiswa sema surfactants uye emulsifiers. Anoratidza kugona kwakanaka kwekuchenesa, kupupuma furo, kudzikamisa furo, kunyorovesa, uye kusanganisa, anoshandiswa zvakanyanya mushampoos, kugeza muviri, sanitizers dzemaoko, uye sipo dzekuwacha.
Pamusoro pezvo, alkyl polyethers dzinoshandiswa se demulsifiers uye lubricants muindasitiri yepeturu, pamwe chete ne coolants uye lubricants mukugadzirisa simbi.
Maitiro ekugadzira alkyl polyethers anowanzo sanganisira kurapwa kwekutanga kwezvishandiso uye macatalyst, ring-opening polymerization reactions, uye matanho ekugadzirisa mushure mekuita akadai se neutralization, adsorption, dehydration, filtration, uye distillation.

Muchidimbu
Muchidimbu, alkyl polyethers, sezvinhu zvemakemikari zvinoshanda zvakasiyana-siyana, inoita basa guru mumaindasitiri akasiyana-siyana. Haisi kungovandudza mashandiro ezvigadzirwa chete uye mhando yazvo asiwo inotsigira kukura kwemaindasitiri emazuva ano. Nekufambira mberi kwetekinoroji, mikana yekushandisa alkyl polyethers ichave yakakura zvakanyanya.
