I-C10 vs C13 i-Alcohol Ethoxylates: Indlela Ubude be-Carbon Chain obuchaphazela ngayo ukusebenza kwe-surfactant

I-Alcohol Ethoxylates zi-nonionic surfactants ezenziwe ngokusabela kwi-alcohols ezinamafutha kunye ne-ethylene oxide. Zisetyenziselwa ngokubanzi ukumanzisa, ukucoca, i-emulsification kunye nokusabalalisa, kodwa iimveliso ngaphakathi kolu sapho aziziphathanga ngendlela efanayo.

Iinkcukacha ezimbini zesakhiwo zifanelwe ingqalelo ngexesha lokukhethwa: i-carbon chain ye-alcohol yokuqala kunye nenani leeyunithi ze-ethylene oxide ezongeziweyo kuyo. I-C10 kunye ne-C13 ichaza i-hydrophobic carbon chain, ngelixa inombolo ye-EO idibene nenxalenye ye-hydrophilic ye-molecule.

Ukufumana ulwazi oluthe kratya malunga nendlela inqanaba le-EO elichaphazela ngayo i-HLB, ukunyibilika kunye nolwalathiso lwesicelo, jonga isikhokelo sethuUkukhetha ibakala le-Alcohol Ethoxylate.

Lo mahluko ubalulekile. Ukuthelekisa ibakala le-C10 kunye nebakala le-C13 ngaphandle kokujonga amanqanaba abo e-EO kunokukhokelela kwisigqibo esingalunganga malunga nokusebenza kwabo.

Ithetha ukuthini i-C10 okanye i-C13?

Inombolo "C" ibhekisa kwinani leathom zekhabhoni kwikhonkco lotywala elisetyenziselwa ukuvelisa i-surfactant. I-C10 Alcohol Ethoxylate isekelwe kwikhonkco elifutshane le-hydrophobic kune-C13 Alcohol Ethoxylate.

Loo mahluko unokuchaphazela indlela i-surfactant edibana ngayo namanzi, umhlaba onamafutha kunye nezinye izithako. Ngokubanzi, ikhonkco elifutshane le-hydrophobic linokuba luncedo xa uqhagamshelwano olukhawulezayo lomphezulu kunye nokusebenza okusekelwe emanzini kubalulekile. Ikhonkco elide linokubonelela ngebhalansi eyahlukileyo yokusebenzisana kweoli, i-emulsification kunye ne-detergency.

Olu lukhetho lokukhetha kunemithetho emiselweyo. Iqondo le-ethoxylation, ukuhanjiswa kweemolekyuli kunye nesakhiwo sotywala bokuqala sichaphazela umphumo wokugqibela.

Indlela Ubude beCarbon Chain obuchaphazela ngayo ukusebenza kweSurfactant

I-C10 kunye ne-C13 ichaza i-hydrophobic carbon chain ye-Alcohol Ethoxylate. Kwinqanaba elifanayo le-EO, i-C10 Alcohol Ethoxylate inekhonkco elifutshane kwaye ibonisa ngokubanzi ukuthambekela okunamandla malunga nokumanzisa okusekelwe emanzini. I-C13 I-Alcohol Ethoxylate inomxokelelwane omde kwaye inokunxibelelana ngamandla kunye ne-oyile kunye nemihlaba ene-hydrophobic.

Apho i-C10 Alcohol Ethoxylate inokuqwalaselwa

C10 Utywala Ethoxylate, eyaziwa nangokuthi i-Decyl Alcohol Ethoxylate, ivandlakanywa ngokuqhelekileyo kwimiqulu apho ukumanzisa okusebenzayo kunye nokusebenza kokucoca okusekelwe emanzini kuyadingeka.

Iindawo ekunokusetyenzwa kuzo zibandakanya:Izicoci zomphezulu oqinileyoIzixokelelwano zokucoca ezizisebenzelayo kunye ne-alkaline yokucoca Imixube ye-alkaline yokumanzisa kunye nezincedisi zokuvasa Imixube yokucoca Imixube yokucocaIsistim sokulima umlimiUmgangatho ofunekayo uya kwahluka ngokwesicelo. Imveliso ejoliswe ikakhulu emulsification inokufuna i-HLB eyahlukileyo kwenye esetyenziselwa ukumanzisa okanye ukucocwa.

I-Dotachem inikezela nge-C10 Alcohol Ethoxylate kwi-1003, 1005, 1007, 1008 kunye ne-1009 amabakala. Uluhlu olukhoyo luvumela abaqulunqi bathelekise amanqanaba e-EO ahlukeneyo kunokuba baphathe i-C10 Alcohol Ethoxylate njengenye, i-surfactant esisigxina.

Xa iBanga le-C13 linokufaneleka ukuthelekisa

I-C13 yoTywala i-Ethoxylateinokubandakanywa kulingo xa ukuqulunqwa kufuna ibhalansi eyahlukileyo phakathi kokuhambelana kwamanzi kunye nokusebenzisana kunye namacandelo amafutha.

Oku kunokufaneleka kwiinkqubo zokucoca, ezilukiweyo, ezicociweyo kwimizi-mveliso nakwizixokelelwano ze-emulsification. Nangona kunjalo, ukutshintsha ukusuka kwi-C10 ukuya kwi-C13 kwakhona kutshintsha inxalenye ye-hydrophobic ye-surfactant. Ukutshintshwa ngokuthe ngqo akufanele kuthathwe ukuhambisa ukuziphatha okufanayo kwe-dilution, i-foam, indawo yefu okanye ukuzinza kwe-emulsion.

Ukhetho alukho nje "i-C10 yamanzi kunye ne-C13 yeoli." Imixube yokwenyani iqulethe izinyibilikisi, i-electrolyte, abakhi kunye nendibaniselwano ye-surfactant enokutshintsha indlela esebenza ngayo nayiphi na imveliso.

Ngenxa yesi sizathu, abaviwa be-C10 kunye ne-C13 kufuneka bakhethwe kumanqanaba afana ne-EO okanye i-HLB nanini na injongo kukufunda umphumo wobude be-carbon chain.

Uluqhuba njani uthelekiso lwe-C10–C13 oluluncedo

Cinga ngesicoci esisekwe emanzini ekufuneka simanzise indawo engcolisekileyo kwaye sincede ukususa intsalela ene-oyile. Umqambi unokukhetha ibakala elinye le-C10 kunye nebakala elinye le-C13 ukuze kuthelekiswe kuqala.

Ukwenza ulingo lube nentsingiselo, ukugxininiswa kwe-surfactant, umgangatho wamanzi, ubushushu, uhlobo lomhlaba, ixesha lokuqhagamshelana kunye nesenzo soomatshini kufuneka sihlale singatshintshi. Abaviwa babini kufuneka babe namanqanaba athelekisekayo e-EO okanye e-HLB ukuba injongo kukufunda umphumo wobude be-carbon chain.

Ukuba iisampulu ezimbini zisebenzisa amanqanaba e-EO ahluke kakhulu, ulingo luya kuba lulinganisa ngaphezu kobude betsheyina lekhabhoni. Isiphumo sisenokunceda ukuchonga ukuqulunqwa okusebenzayo, kodwa akusayi kubonisa ukuba yeyiphi na umahluko wesakhiwo obangele utshintsho ekusebenzeni.

Yintoni omawuyijonge ngaPhantsi koKucocwa koMsebenzi wokuqala

I-surfactant inokunika iziphumo ezilungileyo kwibhetshi entsha yelabhoratri kwaye idale iingxaki kamva. Ukukhethwa kufuneka kubandakanye iimeko eziza kujongana nemveliso egqityiweyo ngexesha lokuvelisa, ukugcinwa kunye nokusetyenziswa.

Iitshekhi eziluncedo ziquka:Ukucaca okanye ukufana emva kokuxubaUzinzo kumaqondo obushushu aphantsi kunye nokugcinwa okuphezuluDilution emanzini anzima kunye athambileyoI-Foam ngexesha lokujikeleza okanye ukutshizaUkuziphatha kokutshizaUkuhambelana nabakhi be-alkaline okanye i-electrolytesUkwahlula emva kokuma Utshintsho kwi-viscosityOlu qwalaselo lubonelela ngexabiso elisebenzisekayo ngaphezu kokukhetha imveliso kuluhlu lwesicelo ngokubanzi.

Ukukhetha iBanga lokuQala ngeDotachem
