Leliphi elinye igama le-hydroxyethyl cellulose?

I-Hydroxyethyl cellulose (HEC) yikhompawundi esetyenziswa ngokubanzi eneenkqubo ezahlukeneyo kumashishini.Eyaziwa nangokuthi i-hydroxyethylcellulose okanye i-HEC, yeyosapho lwe-cellulose ethers, ephuma kwi-cellulose ngokuguqulwa kweekhemikhali.Olu hlengahlengiso lubandakanya ukuqaliswa kwamaqela e-hydroxyethyl kwi-cellulose backbone, eyandisa ukunyibilika kwayo kunye nezinye iimpawu zokusebenza.Ngelixa i-hydroxyethyl cellulose ligama eliqhelekileyo, inokuphinda ibhengezwe ngamanye amagama kwiimeko ezahlukeneyo, kuxhomekeke kwisicelo sayo kunye neshishini elithile elibandakanyekayo.

Kwindawo yekhemistri kunye nokusetyenziswa kwemizi-mveliso, i-hydroxyethyl cellulose inokuthi yaziwe ngegama layo lekhemikhali, i-ethyl hydroxyethyl cellulose okanye ngokulula i-hydroxyethylcellulose.Kurhwebo kunye norhwebo, inokuhamba ngamagama ahlukeneyo emveliso okanye iimpawu zorhwebo, kuxhomekeke kumvelisi okanye umboneleli.La magama anokubandakanya iNatrosol, iCellosize, iBermocoll, kunye namanye, kuxhomekeke kwinkampani evelisa okanye ehambisa imveliso.

Kwizinto zokwakha kunye nezakhiwo, i-hydroxyethyl cellulose isetyenziswa rhoqo njenge-ejenti yokuqina, i-aid yokugcina amanzi, kunye ne-rheology modifier kwiimveliso ezisekelwe kwisamente, ezifana nodaka, i-grouts, kunye ne-cementitious coatings.

Kumayeza kunye neemveliso zokhathalelo lomntu, i-hydroxyethyl cellulose isebenza njengesithako esiguquguqukayo kunye nezicelo kwimixube efana nekhrimu, iiloshini, iishampu, kunye nezisombululo zamehlo.Kwezi mizi-mveliso, inokudweliswa kwiilebhile zemveliso ngegama layo lekhemikhali okanye njenge-ajenti yokujiya, isizinzi, okanye isilungisi se-viscosity.Amanye amagama anokubandakanya iNatrosol, iCellosize, okanye ngokulula i-HEC, kuxhomekeke kuphawu okanye kwimigaqo yokuleyibhile yomenzi.

Kwishishini lokutya nesiselo, i-hydroxyethyl cellulose isetyenziswa njenge-thickener, stabilizer, okanye emulsifier kwiimveliso ezahlukeneyo ukusuka kwiisosi kunye nezinxibo ukuya kwiziselo kunye ne-ayisikrimu.Kulo mongo, kunokubhekiswa kuyo nje nge-HEC okanye ngamagama ayo emveliso ukuba kusetyenziswa iimveliso ezithile zorhwebo.

ngelixa i-hydroxyethyl cellulose ligama lekhemikhali eqhelekileyo yale khompawundi, inokuthi yaziwe ngamanye amagama ahlukeneyo ngokuxhomekeke kushishino, umxholo, kunye nesicelo esithile.La magama angabandakanya amagama orhwebo, amagama eebhrendi, okanye iinkcazelo eziqhelekileyo zomsebenzi walo okanye iipropati.Nokuba yeyiphi na igama elisetyenzisiweyo, i-hydroxyethyl cellulose ihlala isisithako esixabisekileyo nesiguquguqukayo kunye nosetyenziso oluxhaphakileyo kumashishini amaninzi.
