Ukusetshenziswa okuhle kwe-Stearic Acid

I-Stearic acid, noma i-octadecanoic acid, ifomula yamangqamuzana C18H36O2, ikhiqizwa i-hydrolysis yamafutha namafutha futhi isetshenziswa kakhulu ekukhiqizeni ama-stearates. Igram ngayinye incibilika ku-21ml ethanol, 5ml benzene, 2ml chloroform noma 6ml carbon tetrachloride. Inengcina emhlophe ebonisa ngale okuqinile noma okuphuzi kancane, ingahlakazwa ibe yimpushana, kancane enephunga lebhotela. Njengamanje, ingxenye enkulu yokukhiqizwa kwasekhaya kwamabhizinisi e-stearic acid athunyelwa kwamanye amazwe avela phesheya amafutha esundu, i-hydrogenation kuwoyela oqinisiwe, bese kuba i-hydrolysis distillation ukwenza i-stearic acid.

I-Stearic acid isetshenziswa kabanzi kuzimonyo, ama-plasticizers epulasitiki, ama-ejenti akhulula isikhunta, ama-stabilizers, ama-surfactants, ama-accelerator e-rubber vulcanisation, izinto zokuxosha amanzi, ama-agent okupholisha, insipho yensimbi, i-metal mineral flotation agents, izithambisa, imithi kanye namanye amakhemikhali aphilayo. I-Stearic acid ingasetshenziswa futhi njengesinyibilikisi semibala encibilikayo kawoyela, i-crayon sliding agent, i-wax paper polishing agent, kanye ne-emulsifier ye-glycerol stearate. I-Stearic acid ibuye isetshenziswe kabanzi ekwenzeni amapayipi epulasitiki e-PVC, amapuleti, amaphrofayili namafilimu, futhi iyisinzisi sokushisa se-PVC esinokugcoba okuhle nokukhanya okuhle nokuzinza kokushisa.

I-Mono- noma i-polyol esters ye-stearic acid ingasetshenziswa njengezimonyo, ama-non-ionic surfactants, ama-plasticisers njalonjalo. Usawoti wayo wensimbi ye-alkali uyancibilika emanzini futhi ungenye yezingxenye eziyinhloko zensipho, kuyilapho amanye amasawoti ensimbi angasetshenziswa njengezixosha amanzi, izithambisi, izibulala-sikhunta, izithasiselo zikapende kanye nama-PVC stabiliser.

Indima ye-stearic acid ezintweni ze-polymeric iboniswa amandla ayo okuthuthukisa ukuzinza kwe-thermal. Izinto ze-polymer zijwayele ukuwohloka kanye ne-oxidation ngesikhathi sokucubungula izinga lokushisa eliphezulu, okuholela ekwehleni kokusebenza. Ukwengezwa kwe-stearic acid kunganciphisa ngokuphumelelayo le nqubo yokuwohloka futhi kunciphise ukuphuka kwamaketanga wamangqamuzana, ngaleyo ndlela kwandise impilo yesevisi yezinto. Lokhu kubaluleke kakhulu ekwakhiweni kwemikhiqizo evikela izinga lokushisa eliphezulu njengokufakwa kwezintambo nezingxenye zezimoto.

I-Stearic acid inezakhiwo ezinhle kakhulu zokugcoba njengesithambiso. Ezintweni ze-polymer, i-stearic acid inciphisa ukungqubuzana phakathi kwamaketanga wamangqamuzana, ivumela izinto ukuthi zigeleze kalula, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwenqubo. Lokhu kuzuzisa kakhulu ezinqubweni zokukhiqiza ezifana nokubumba umjovo, i-extrusion kanye ne-calendering.

I-Stearic acid ikhombisa umphumela we-plasticiser ezintweni ze-polymeric, okwandisa ukuthamba kanye nokusebenziseka kalula kwezinto. Lokhu kwenza izinto kube lula ukubumba zibe yizimo ezihlukahlukene, okuhlanganisa amafilimu, amashubhu namaphrofayili. Umphumela we-plasticising we-stearic acid uvame ukusetshenziswa ekukhiqizeni amaphakethe epulasitiki, izikhwama zepulasitiki neziqukathi zepulasitiki.

Izinto ezisetshenziswayo ze-polymeric zivame ukuthambekela ekumunceni amanzi, ezingahle zilulaze izakhiwo zazo futhi zibangele ukugqwala. Ukwengezwa kwe-stearic acid kuthuthukisa ukuxoshwa kwamanzi kwento, kuvumela ukuthi ihlale izinzile ezindaweni ezimanzi. Lokhu kubaluleke kakhulu ezindaweni ezifana nemikhiqizo yangaphandle, izinto zokwakha kanye nezindlu zemishini kagesi.

I-Stearic acid isiza ukunciphisa ukushintsha kombala wezinto ze-polymeric ku-UV kanye nezindawo ezishisayo. Lokhu kubalulekile ekwenziweni kwemikhiqizo ezinzile enombala njengamabhodi okukhangisa angaphandle, izingxenye zangaphakathi zezimoto kanye nefenisha yangaphandle.

I-Stearic acid isebenza njenge-anti-adhesive kanye ne-flow aid ezintweni ze-polymeric. Inciphisa ukunamathela phakathi kwama-molecule futhi yenza izinto zigeleze kalula, ikakhulukazi ngesikhathi sokubumba umjovo. Lokhu kuthuthukisa ukukhiqiza futhi kunciphisa amaphutha emkhiqizweni.

I-Stearic acid isetshenziswa njenge-anti-caking ejenti ekukhiqizeni umanyolo ohlanganisiwe ukuqinisekisa ukuhlakazeka okufanayo kwezinhlayiya zikamanyolo. Lokhu kusiza ukwenza ngcono izinga kanye nokufana komanyolo futhi kuqinisekise ukuthi izitshalo zithola imisoco efanele.

I-Stearic acid isetshenziswa ezinhlobonhlobo zezicelo zezimboni nabathengi.
