Babban amfani ga stearic acid

Stearic acid, ko octadecanoic acid, tsarin kwayoyin C18H36O2, ana samar da shi ta hanyar hydrolysis na fats da mai kuma ana amfani da shi musamman wajen samar da stearates. Ana narkar da kowane gram a cikin 21ml ethanol, 5ml benzene, 2ml chloroform ko 6ml carbon tetrachloride. Farin kakin zuma ne mai kauri ko rawaya mai kauri, ana iya tarwatsa shi cikin foda, dan kadan tare da warin man shanu. A halin yanzu, yawancin masana'antar stearic acid a cikin gida ana shigo da su daga ƙasashen waje na dabino, hydrogenation zuwa mai mai tauri, sa'an nan kuma distillation hydrolysis don yin stearic acid.

Stearic acid ana amfani dashi ko'ina a cikin kayan shafawa, filastik filastik, wakilai na saki mold, stabilizers, surfactants, roba vulcanisation accelerators, ruwa masu hana ruwa, polishing jamiái, karfe sabulu, karfe flotation jamiái, softeners, Pharmaceuticals da sauran Organic sunadarai. Stearic acid kuma za a iya amfani da a matsayin sauran ƙarfi ga mai-mai narkewa pigments, wani crayon zamiya wakili, kakin zuma polishing wakili, da emulsifier ga glycerol stearate. Stearic acid kuma ana amfani dashi ko'ina a cikin kera bututun filastik na PVC, faranti, bayanan martaba da fina-finai, kuma shine mai tabbatar da zafi don PVC tare da lubricity mai kyau da haske mai kyau da kwanciyar hankali.

Mono- ko polyol esters na stearic acid za a iya amfani da su a matsayin kayan shafawa, wadanda ba ionic surfactants, plasticisers da sauransu. Gishirin sa na ƙarfe na alkali yana narkewa a cikin ruwa kuma yana ɗaya daga cikin abubuwan da ke cikin sabulu, yayin da sauran gishirin ƙarfe za a iya amfani da su azaman masu kawar da ruwa, man shafawa, kayan gwari, kayan fenti da PVC stabilisers.

Matsayin stearic acid a cikin kayan polymeric yana nunawa ta ikonsa na haɓaka kwanciyar hankali na thermal. Abubuwan polymers suna da haɗari ga lalacewa da oxidation a lokacin sarrafa yawan zafin jiki, yana haifar da raguwa a cikin aiki. Bugu da ƙari na stearic acid zai iya rage jinkirin wannan tsari na lalata da kuma rage raguwa na sassan kwayoyin halitta, don haka ya kara tsawon rayuwar kayan aiki. Wannan yana da mahimmanci musamman wajen kera samfuran masu juriya masu zafi kamar su rufin waya da kayan aikin mota.

Stearic acid yana da kyawawan kaddarorin lubricating azaman mai mai. A cikin kayan polymer, stearic acid yana rage juzu'i tsakanin sarƙoƙi na ƙwayoyin cuta, ƙyale abu ya gudana cikin sauƙi, don haka inganta ingantaccen tsari. Wannan yana da matukar fa'ida ga hanyoyin samarwa kamar gyare-gyaren allura, extrusion da calending.

Stearic acid yana nuna tasirin filastik a cikin kayan polymeric, yana ƙaruwa da laushi da rashin ƙarfi na kayan. Wannan yana sa kayan ya fi sauƙi don ƙirƙira zuwa nau'i-nau'i iri-iri, ciki har da fina-finai, tubes da bayanan martaba. Ana amfani da tasirin filastik na stearic acid sau da yawa a cikin samar da fakitin filastik, jakunkuna da kwantena filastik.

Abubuwan Polymeric sau da yawa suna da wuyar sha ruwa, wanda zai iya lalata kaddarorin su kuma ya haifar da lalata. Bugu da ƙari na stearic acid yana inganta haɓakar ruwa na kayan abu, yana ba shi damar kasancewa a cikin yanayin rigar. Wannan yana da mahimmiyar mahimmanci a fannoni kamar samfuran waje, kayan gini da gidajen na'urorin lantarki.

Stearic acid yana taimakawa wajen rage canjin launi na kayan polymeric a cikin UV da yanayin zafi. Wannan yana da mahimmanci wajen kera samfuran barga masu launi kamar allunan talla na waje, sassan ciki na mota da kayan waje.

Stearic acid yana aiki azaman anti-manne da taimako mai gudana a cikin kayan polymeric. Yana rage mannewa tsakanin kwayoyin halitta kuma yana sa kayan su gudana cikin sauƙi, musamman yayin aikin gyaran allura. Wannan yana inganta yawan aiki kuma yana rage lahani a cikin samfurin.

Ana amfani da stearic acid azaman wakili na anti-caking a cikin masana'antar takin mai magani don tabbatar da rarrabuwa iri ɗaya na barbashi taki. Wannan yana taimakawa wajen haɓaka inganci da daidaiton takin kuma yana tabbatar da cewa tsire-tsire sun sami ingantaccen abinci mai gina jiki.

Stearic acid ana amfani dashi a cikin masana'antu iri-iri da aikace-aikacen mabukaci.
