I-MEHEC iyongezo eyimfuneko ekuqulunqweni kwe-adhesives yamanzi kunye ne-sealants. Iphucula i-tack, i-viscosity, kunye nexesha elivulekileyo lokunamathelisa, ukuququzelela ukusebenza kakuhle kokubambisana kwii-substrates ezahlukeneyo. Kwii-sealants, i-MEHEC inceda ukufezekisa i-extrudability efanelekileyo, i-thixotropy, kunye nokubambelela, ukuqinisekisa ukutywinwa okusebenzayo kwamalungu kunye nezikhala kulwakhiwo kunye nezicelo zeemoto.

4.Iimveliso zoKhathalelo loBuqu:

Ngenxa yokwenziwa kwefilimu kunye neempawu ezityebileyo, i-MEHEC isetyenziselwa ukhathalelo lomntu kunye neemveliso zokuthambisa. Inokufumaneka ekuqulunqweni kweekhrimu, i-lotions, i-shampoos, kunye neegels zeshawa, apho iphucula ukuthungwa, ukuzinza, kunye neempawu zokuthambisa. I-MEHEC iphinda isebenze njenge-ejenti yokumisa iinqununu eziqinileyo kwiifom zokunakekelwa komntu, ukukhusela i-sedimentation kunye nokuqinisekisa ukusabalalisa okufanayo.

5.Amayeza:

I-MEHEC isebenza njenge-binder, i-thickener, kunye ne-stabilizer kwimixube yamachiza efana neepilisi, iikhrimu, kunye nokuxhonywa. Ikhono layo lokulawula i-viscosity kunye nokuphucula i-flow properties iqinisekisa ukuhanjiswa kweziyobisi okufanayo kunye ne-dosing engaguqukiyo. Ekuqulunqweni kweengqungquthela, i-MEHEC ibonelela ngokucokisekileyo kunye nokungabikho kwegreasy ngelixa iphucula ukunamathela kwezithako ezisebenzayo kwesikhumba.

6.Ishishini lokuTya kunye neziselo:

Nangona kuncinci okuqhelekileyo xa kuthelekiswa nezinye izicelo, i-MEHEC isetyenziswa ngamaxesha athile kwishishini lokutya kunye nesiselo njenge-ejenti yokuqina kunye nokuzinzisa. Inokufumaneka kwiimveliso ezithile zokutya ezifana neesosi, izinxibo kunye neziselo, apho iphucula ukuthungwa, ukuvakala komlomo, kunye nokuzinza kweshelufu ngaphandle kokutshintsha incasa okanye ivumba.

7.Ishishini le-oyile negesi:

I-MEHEC ifumana isicelo kwi-drilling fluids kunye ne-samente slurries esetyenziswa kwishishini leoli kunye negesi. Inceda ukulawula i-viscosity yolwelo, ukumisa amasuntswana aqinileyo, kunye nokuthintela ukulahleka kolwelo ngexesha lomsebenzi wokomba. Ulwelo oluphuculweyo lwe-MEHEC luqinisekisa uzinzo olusebenzayo lwe-wellbore, ukuthambisa, kunye nokususwa kwe-drill cuttings, igalelo kwimpumelelo yonke yokusebenza kokomba.

8.Ishishini leMizobo:

I-MEHEC isetyenziswa kushicilelo lwelaphu kunye neenkqubo zokudaya njenge-thickener kunye ne-rheology modifier yokuprinta iipasti kunye neebhafu zedayi. Iphucula ukungaguquguquki kunye nokuhamba kweempawu zokuprinta iintlama, iqinisekisa ngokuchanekileyo kunye nokubekwa okufanayo kwemibala kwi-substrates ye-textile. I-MEHEC ikwanceda ekuthinteleni ukopha kombala kunye nokuphucula ukubukhali kweepateni eziprintiweyo.

9.Ezinye izicelo zoShishino:

I-MEHEC ifumana usetyenziso oluxutyiweyo kumashishini afana nezicoci, ukwenziwa kwamaphepha, kunye neeseramikhi. Kwi-detergents, iphucula ukuzinza kunye ne-rheology yokwenziwa kwe-liquid formulations, ngelixa kwimveliso yephepha, iphucula amandla ephepha kunye nokugcinwa kweefayili kunye nezongezo. Kwi-ceramics, i-MEHEC isebenza njenge-binder kunye ne-rheology modifier kwi-ceramic slurries, ukuququzelela ukubunjwa kunye neenkqubo zokubumba.

I-methyl ethyl hydroxyethyl cellulose (MEHEC) yi-ether yeselulosi esebenza ngeendlela ezininzi esetyenziswa ngokubanzi kuwo wonke amashishini. Ukudibanisa kwayo okuyingqayizivele kwezakhiwo, kubandakanywa ukuqina, ukugcinwa kwamanzi, ukubunjwa kwefilimu, kunye nokukwazi ukunqunyanyiswa, kwenza ukuba ibe yinto eyongezelelweyo exabisekileyo ekuqulunqweni okuvela kwiipeyinti kunye neengubo kwiimveliso zokunyamekela komntu, amayeza, nangaphezulu. I-MEHEC inegalelo ekwandiseni ukusebenza kwemveliso, ukusebenza kakuhle, kunye namava omsebenzisi wokugqibela kuzo zonke iintlobo zezicelo, ngaloo ndlela idlala indima ebalulekileyo kumacandelo amaninzi emizi-mveliso.
