Yonke into omele uyazi malunga neMethyl Hydroxyethyl Cellulose (MHEC)

I-Methyl Hydroxyethyl Cellulose (MHEC) i-cellulose ether derivative efumana ukusetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nokusebenza. Nantsi yonke into okufuneka uyazi malunga neMethyl Hydroxyethyl Cellulose (MHEC):

1. Ulwakhiwo lweMichiza:

I-MHEC yi-methyl ether ye-hydroxyethyl cellulose, apho zombini i-methyl (-CH3) kunye ne-hydroxyethyl (-CH2CH2OH) amaqela athatyathwa kwi-backbone ye-cellulose. Esi sakhiwo sekhemikhali sinikezela iipropati ezithile kwi-MHEC, okwenza kube luncedo kwiintlobo ezahlukeneyo zezicelo.

2. Iinkcazelo ngeempawu:

a. Ukunyibilika kwamanzi:

I-MHEC i-soluble emanzini, yenza izisombululo ezicacileyo, ezicacileyo. I-solubility kunye ne-viscosity yezisombululo ze-MHEC zixhomekeke kwizinto ezifana nobunzima be-molecular, i-degree of substitution, kunye nokushisa.

b. Ukutyebisa:

I-MHEC isebenza njenge-agent esebenzayo yokuqina kwizisombululo ezinamanzi. Inika i-pseudoplastic (shear-thinning) ukuziphatha, oku kuthetha ukuba i-viscosity yayo iyancipha phantsi koxinzelelo lwe-shear. Le propati inenzuzo kwizicelo apho i-viscosity ezinzile phantsi kweemeko ezahlukeneyo kufuneka.

c. Ukwenza ifilimu:

I-MHEC inezakhiwo zokwenza ifilimu, evumela ukuba yenze iifilimu eziguquguqukayo kunye nezidibeneyo xa zomiswe. Ezi filimu zinokubonelela ngeepropati zomqobo, ukubambelela, kunye nokukhusela kwi-substrates kwizicelo ezahlukeneyo.

d. Ugcino lwamanzi:

I-MHEC ibonisa iimpawu zokugcina amanzi, inceda ukugcina amanqanaba omswakama ekuqulunqweni kunye ne-substrates. Le propati ibaluleke kakhulu kwizinto zokwakha, apho kufuneka i-hydration ixesha elide kunye nokusebenza.

e. Ukunamathela kunye noManyano:

I-MHEC iphucula ukubambelela kunye nokubambisana ekuqulunqweni, ukukhuthaza ukudibanisa phakathi kweengqungquthela okanye iindawo. Iphucula ukusebenza kunye nokuqina kwezinto zokuncamathelisa, iingubo, kunye nezinye iimveliso ezenziweyo.

3. Usetyenziso:

a. Izinto zokwakha:

I-MHEC isetyenziswa ngokubanzi kwizinto zokwakha ezifana nodaka, i-renders, i-grouts, kunye ne-adhesives tile. Isebenza njenge-thickener, i-arhente yokugcina amanzi, kunye ne-rheology modifier, ukuphucula ukusebenza, ukunamathela, kunye nokuqina kweemveliso zesamente.

b. Iipeyinti kunye neeNqaku:

I-MHEC yongezwa kwiipeyinti ezisekelwe emanzini, iingubo, kunye ne-adhesives njenge-thickener kunye ne-rheology modifier. Iphucula ulawulo lwe-viscosity, ukuxhathisa kwe-sag, kunye nokwakheka kwefilimu, ekhokelela ekugqumeni ngcono kunye nokubambelela kwii-substrates ezahlukeneyo.

c. Iimveliso zokuKhathalela umntu:

I-MHEC ifumaneka kukhathalelo lomntu kunye neemveliso zokuthambisa ezifana neekhrimu, iiloshini, iishampu, kunye neegels. Isebenza njenge-thickener, i-emulsifier, kunye ne-stabilizer, inika ukuthungwa, i-viscosity, kunye nokuzinza kwiifomyula.

d. Amachiza:

I-MHEC isetyenziselwa ukuqulunqa amayeza njenge-binder, i-disintegrant, kunye ne-ejenti elawulwayo yokukhutshwa kwiipilisi kunye neepilisi. Iphucula iipropathi zethebhulethi ezinje ngokuqina, izinga lokunyibilika, kunye neprofayili yokukhutshwa kweziyobisi.

Isiphelo:

I-Methyl Hydroxyethyl Cellulose (MHEC) i-ether ye-cellulose ehlukeneyo kunye neendawo ezininzi kunye nokusetyenziswa. Ukunyibilika kwayo kwamanzi, ukutyeba, ukwenza ifilim, ukugcinwa kwamanzi, kunye neempawu zokuncamathela kuyenza ixabiseke kumashishini afana nokwakha, iipeyinti kunye neengubo zokwaleka, ukhathalelo lomntu, kunye namayeza. Njengesongezo esisebenzayo, i-MHEC inegalelo ekusebenzeni, ukusebenza, kunye nokuzinza kweemveliso ezicwangcisiweyo kuzo zonke izicelo ezahlukeneyo.
