Kugwiritsa ntchito bwino kwa Stearic Acid

Stearic acid, kapena octadecanoic acid, molecular formula C18H36O2, amapangidwa ndi hydrolysis ya mafuta ndi mafuta ndipo amagwiritsidwa ntchito makamaka popanga stearates. Galamu iliyonse imasungunuka mu 21ml ethanol, 5ml benzene, 2ml chloroform kapena 6ml carbon tetrachloride. Ndi phula loyera lowoneka bwino kapena lachikasu pang'ono, limatha kumwazikana kukhala ufa, wonunkhira pang'ono ndi batala. Pakalipano, mabizinesi ambiri apanyumba a stearic acid amatumizidwa kuchokera kunja kwa mafuta a kanjedza, hydrogenation kukhala mafuta owumitsidwa, kenako hydrolysis distillation kupanga stearic acid.

Asidi Stearic chimagwiritsidwa ntchito zodzoladzola, plasticizers pulasitiki, nkhungu kumasula wothandizila, stabilizers, surfactants, mphira vulcanisation accelerators, repellents madzi, wothandizila kupukuta, zitsulo sopo, zitsulo mchere flotation wothandizira, softeners, mankhwala ndi mankhwala ena organic. Asidi wa Stearic atha kugwiritsidwanso ntchito ngati zosungunulira zosungunulira zosungunulira mafuta, khrayoni yotsetsereka, phula lopukuta mapepala, ndi emulsifier ya glycerol stearate. Stearic acid imagwiritsidwanso ntchito kwambiri popanga mapaipi apulasitiki a PVC, mbale, mbiri ndi mafilimu, ndipo ndi stabilizer yotentha ya PVC yokhala ndi lubricity yabwino komanso kuwala kwabwino komanso kukhazikika kwa kutentha.

Mono- kapena polyol esters of stearic acid angagwiritsidwe ntchito ngati zodzoladzola, zopanda ma ionic surfactants, plasticisers ndi zina zotero. Mchere wake wamchere wamchere umasungunuka m'madzi ndipo ndi chimodzi mwa zigawo zazikulu za sopo, pamene mchere wina wachitsulo ukhoza kugwiritsidwa ntchito ngati zothamangitsira madzi, mafuta odzola, fungicides, zowonjezera utoto ndi PVC stabilisers.

Ntchito ya stearic acid muzinthu za polymeric ikuwonetsedwa ndi kuthekera kwake kolimbikitsa kukhazikika kwamafuta. Zida za polima zimatha kuwonongeka ndi okosijeni panthawi yotentha kwambiri, zomwe zimapangitsa kuchepa kwa magwiridwe antchito. Kuphatikiza kwa stearic acid kumatha kuchedwetsa bwino izi ndikuchepetsa kusweka kwa unyolo wa maselo, motero kumakulitsa moyo wautumiki wa zinthuzo. Izi ndizofunikira makamaka popanga zinthu zolimbana ndi kutentha kwambiri monga kutsekereza waya ndi zida zamagalimoto.

Asidi wa Stearic ali ndi mafuta abwino kwambiri opaka mafuta. M'zinthu za polima, stearic acid imachepetsa kukangana pakati pa maunyolo a maselo, kulola kuti zinthu ziziyenda mosavuta, motero zimapangitsa kuti ntchitoyi ikhale yabwino. Izi ndizopindulitsa kwambiri pakupanga njira monga kuumba jekeseni, extrusion ndi calendering.

Stearic acid amawonetsa pulasitiki muzinthu zapolymeric, kukulitsa kufewa komanso kusinthika kwazinthuzo. Izi zimapangitsa kuti zinthuzo zikhale zosavuta kuumba mumitundu yosiyanasiyana, kuphatikiza mafilimu, machubu ndi mbiri. Mphamvu ya pulasitiki ya stearic acid nthawi zambiri imagwiritsidwa ntchito popanga mapulasitiki, matumba apulasitiki ndi zotengera zapulasitiki.

Zipangizo za polymeric nthawi zambiri zimakhala ndi madzi, zomwe zimatha kusokoneza katundu wawo ndikuyambitsa dzimbiri. Kuphatikizika kwa stearic acid kumathandizira kuthamangitsa madzi kwa zinthuzo, ndikupangitsa kuti ikhale yokhazikika m'malo onyowa. Izi ndizofunikira kwambiri m'malo monga zinthu zakunja, zida zomangira komanso nyumba zopangira zida zamagetsi.

Stearic acid imathandizira kuchepetsa kusintha kwa mtundu wa zinthu za polymeric mu UV ndi malo otentha. Izi ndizofunikira popanga zinthu zokhazikika zamtundu monga zikwangwani zakunja, zida zamkati zamagalimoto ndi mipando yakunja.

Stearic acid imagwira ntchito ngati anti-zomatira ndikuthandizira kuyenda muzinthu za polymeric. Amachepetsa kumamatira pakati pa mamolekyu ndikupanga zinthu kuyenda mosavuta, makamaka panthawi yopangira jekeseni. Izi zimakulitsa zokolola komanso zimachepetsa zolakwika zomwe zimapangidwa.

Stearic acid imagwiritsidwa ntchito ngati anti-caking wothandizira pakupanga feteleza wapawiri kuti awonetsetse kuti tinthu tating'onoting'ono ta feteleza timabalalika. Izi zimathandiza kuti feteleza akhale wabwino komanso wofanana komanso kuti zomera zilandire zakudya zoyenera.

Stearic acid imagwiritsidwa ntchito m'mafakitale osiyanasiyana komanso ogula.
