Yintoni i-MHEC Methyl hydroxyethyl cellulose?

I-Methyl Hydroxyethyl Cellulose (MHEC): Isishwankathelo esiBanzi

Intshayelelo:

I-Methyl Hydroxyethyl Cellulose, edla ngokufinyezwa njenge-MHEC, yi-ether ye-cellulose ethe yafumana ukuvelela kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye neziguquguqukayo. Le khemikhali iphuma kwiselulosi ifumana izicelo kulwakhiwo, kumayeza, kwizinto zokuthambisa, nokunye. Kolu phononongo olubanzi, singena kwisakhiwo, iipropati, iinkqubo zokuvelisa, kunye nezicelo ezahlukeneyo ze-MHEC.

Ulwakhiwo lweMichiza:

I-MHEC i-ether ye-cellulose eguqulwayo ephuma kwi-cellulose ye-polymer yendalo, i-carbohydrate eyinkimbinkimbi equkethe iiyunithi ze-glucose. Ukuguqulwa kubandakanya ukwazisa amaqela e-methyl kunye ne-hydroxyethyl kwi-cellulose backbone. Olu tshintsho lunika iimpawu ezithile kwi-MHEC, yenze ukuba ilungele uluhlu olubanzi lwezicelo.

Iipropati ze-MHEC:

1. Ukutyeba kunye noLawulo lweViscosity:

I-MHEC idume ngeepropati zayo ezityebileyo, iyenza i-arhente esebenzayo yokulawula i-viscosity yezisombululo. Olu phawu lubaluleke kakhulu kumashishini apho ulawulo lwerheological oluchanekileyo luyimfuneko, njengaxa kusenziwa iipeyinti, izinto zokuncamathelisa, kunye neemveliso zolwelo ezahlukeneyo.

2. Ugcino lwamanzi:

Enye yezinto eziphawulekayo ze-MHEC kukukwazi ukugcina amanzi. Kwindawo yezinto zokwakha, ezifana nodaka kunye nesamente, i-MHEC isebenza njenge-agent egqwesileyo yokugcina amanzi. Esi sixhobo sinceda ukuthintela ukomisa ngokukhawuleza, ukuphucula ukusebenza kunye nokubambelela ekusebenziseni ezi zixhobo.

3. Isidibanisi kwiiMveliso zoKwakha:

I-MHEC idlala indima ebalulekileyo njengesibophelelo ekwenziweni kweemveliso zokwakha. I-adhesives ye-tile, i-cement-based renders, kunye neengqungquthela ezidibeneyo zixhamla ekongezwa kwe-MHEC, ephucula ukusebenza kwazo zonke kunye nokuqina.

4. Izicelo zezamayeza kunye nezeZithambiso:

Amashishini amayeza kunye ne-cosmetic amkele i-MHEC ngenxa yobuninzi bayo. Ekuqulunqweni kwamachiza, i-MHEC isebenza njenge-thickener, i-stabilizer, kunye ne-binder kwiifom ezahlukeneyo ze-dosage, kubandakanywa amayeza omlomo kunye nezicelo ze-topical ezifana ne-ointments kunye ne-creams. Ngokufanayo, imboni yezithambiso ibandakanya i-MHEC ngokukwazi kwayo ukuphucula ukuthungwa kunye nokuzinza kweemveliso.

5. IiPropati zokuSebenza ifilimu:

I-MHEC ibonisa iipropati zokwenza ifilimu, eyenza ukuba ifaneleke kwizicelo kwiingubo kunye nokunamathela. Olu phawu lunegalelo ekubunjweni kwefilimu edibeneyo kunye nokukhusela, ukuphucula ukusebenza kwemveliso yokugqibela.

Inkqubo yokuVelisa:

Ukuveliswa kwe-MHEC kubandakanya amanyathelo amaninzi, ngokuqala ngokutsalwa kwe-cellulose kwimithombo esekelwe kwizityalo. I-Wood pulp sisixhobo sokuqala esixhaphakileyo, nangona eminye imithombo efana nomqhaphu kunye nezinye izityalo ezinentsinga zinokusetyenziswa. Emva koko i-cellulose iphantsi kokuguqulwa kweekhemikhali ngokusebenzisa iinkqubo ze-etherification, ukwazisa amaqela e-methyl kunye ne-hydroxyethyl kwikhonkco le-cellulose. Iqondo lokutshintshwa kunye nobunzima be-molecular bunokulawulwa ngexesha lokuvelisa, ukuvumela ukulungelelaniswa kwe-MHEC ukuhlangabezana neemfuno ezithile zesicelo.

Usetyenziso lwe-MHEC:

1. Ushishino loKwakha:

I-MHEC ifumana ukusetyenziswa ngokubanzi kwishishini lokwakha. Njenge-arhente yokugcina amanzi, iphakamisa ukusebenza kwezixhobo zesamente, kuquka udaka kunye ne-grouts. Iimpawu zayo ezibophezelayo zifaka isandla ekuqulunqweni kwe-adhesives tile adhesives high-performance, i-plaster, kunye nezixhobo ezidibeneyo.

2. Uqulunqo lwezamayeza:

Kwicandelo lamachiza, i-MHEC iqeshwe kwiindlela ezahlukeneyo. Indima yayo njenge-ejenti yokuqina kunye ne-binder ibalulekile ekuveliseni iipilisi, ii-capsules, kunye ne-topical formulations. Iinkqubo zokuhanjiswa kweziyobisi ezilawulwayo zinokuthi zizuze kwiipropati ze-rheological ze-MHEC.

3. Izithambiso kunye neeMveliso zokuKhathalela umntu:

Ukuqulunqwa kwe-Cosmetic kuhlala kubandakanya i-MHEC ukufezekisa ukuthungwa okufunwayo, ukuzinza, kunye ne-viscosity. Iikhrimu, ii-lotion, kunye neegels zinokusebenzisa i-MHEC njenge-thickener kunye ne-stabilizer, igalelo kumgangatho opheleleyo kunye nobomi beshelufu yezi mveliso.

4. Iipeyinti kunye neeNqaku:

Ishishini lepeyinti kunye nokwaleka liphakamisa i-MHEC ngenxa yokuqina kwayo kunye neempawu zefilimu. Inceda ekuthinteleni ukuthoba okanye ukuvuza ngexesha lokufaka isicelo kwaye igalelo ekwenziweni kwengubo efanayo kunye neyokuhlala ixesha elide.

5. Izinto ezincamathelayo:

I-MHEC idlala indima ekuqulunqweni kwe-adhesives, igalelo kwi-viscosity yabo kunye namandla okubambelela. Iipropathi zayo zokwenza ifilimu ziphucula ukusebenza kwekhonkco lokuncamathelisa kuzo zonke ii-substrates ezahlukeneyo.

Iingqwalasela zokusiNgqongileyo kunye noLawulo:

Njengayo nayiphi na imichiza, imiba yokusingqongileyo kunye nolawulo lwe-MHEC yingqwalasela ebalulekileyo. Ukonakaliswa kwe-biodegradability ye-MHEC, kunye nempembelelo enokubakho kwi-ikhosistim kunye nempilo yabantu, kufuneka kuhlolwe ngocoselelo. Iibhodi ezilawulayo, ezifana ne-Environmental Protection Agency (EPA) kunye nee-arhente zamazwe ngamazwe ezifanelekileyo, zinokubonelela ngezikhokelo zokusetyenziswa ngokukhuselekileyo kunye nokulahlwa kweemveliso eziqulethe i-MHEC.

I-Methyl Hydroxyethyl Cellulose, kunye nendibaniselwano ekhethekileyo yeepropathi, iye yaba yinxalenye eyimfuneko kwizicelo ezahlukeneyo zemizi-mveliso. Ukususela ekuphuculeni ukusebenza kwezinto zokwakha ukufaka isandla ekuthunjweni nasekuzinzeni kwamachiza kunye nezithambiso, i-MHEC iyaqhubeka nokudlala indima ebalulekileyo. Njengoko amashishini aguqukayo kunye nemfuno yezinto ezizinzileyo nezisebenzayo zikhula, ukuguquguquka kwe-MHEC kubeka njengomdlali ophambili kumhlaba wesayensi yezinto zanamhlanje. Uphando oluqhubekayo kunye nophuhliso luya kutyhila izinto ezintsha ezinokwenzeka kunye nezicelo, ngakumbi ukuqinisa ukubaluleka kwe-MHEC ekumiseni ikamva lamashishini amaninzi.
