I-Hydroxy ethyl methyl cellulose

IHydroxy ethyl methyl cellulose (HEMC), ekwabizwa ngokuba yi-methyl hydroxy ethyl cellulose (MHEC), iyipolymer eguquguqukayo evela kwiselulosi. Idityaniswe ngokuguqulwa kweekhemikhali zeselulosi, okukhokelela kwikhompawundi eneempawu ezizodwa ezifanelekileyo kwizicelo ezahlukeneyo zamashishini. I-HEMC lilungu lentsapho ye-cellulose ether kwaye yabelana ngokufana nezinye izinto eziphuma kuzo ezifana ne-methyl cellulose (MC) kunye ne-hydroxypropyl methyl cellulose (HPMC).

Iimpawu eziphambili zeHydroxy ethyl Methyl Cellulose (HEMC):

I-1.I-Solubility yamanzi: I-HEMC iyanyibilika emanzini, yenza izisombululo ezicacileyo kunye ne-viscous. Le propati ivumela ukuphathwa ngokulula kunye nokufakwa kwiinkqubo zamanzi, okwenza ukuba zilungele ukusetyenziswa kwiindlela ezininzi zokuqulunqa.

I-Agent ye-2.Thickening: I-HEMC isebenza njenge-agent esebenzayo yokuqina kwimiqulu esekwe emanzini. Xa ichithwa emanzini, iintambo ze-polymer ze-HEMC zidibanisa kwaye zenze isakhiwo senethiwekhi, ukwandisa i-viscosity yesisombululo. Le propati ibalulekile ekulawuleni i-rheology kunye nokuhamba kweempawu zepeyinti, i-adhesives, kunye nezinye iimveliso zolwelo.

I-3.I-Film-Forming Ability: I-HEMC inamandla okwenza iifilimu xa isetyenziswe kwiindawo kwaye ivunyelwe ukuba yome. Ezi filimu ziselubala, zibhetyebhetye, kwaye zibonisa ukubambelela kakuhle kwii-substrates ezahlukeneyo. Iifilimu ze-HEMC zisetyenziswa kwizicelo ezinje ngeengubo, izinto zokuncamathelisa, kunye nezinto zokwakha.

4.Ukugcinwa kwamanzi okuphuculweyo: I-HEMC iyaziwa ngeempawu zayo zokugcina amanzi, ezinceda ukukhusela ukulahleka komswakama kunye nokugcina ukuhambelana okufunwayo kokuqulunqwa kwexesha. Le propati ibaluleke kakhulu kwizinto zokwakha ezifana nodaka, i-grouts, kunye ne-adhesives yethayile, apho kufuneka ukusebenza ixesha elide.

I-5.Ukuphuculwa kokuSebenza kunye nokuBambisana: Ukongezwa kwe-HEMC ekuqulunqweni kunokuphucula ukusebenza ngokunyusa ukuhamba kunye nokusasazeka kwezinto. Kwakhona kukhuthaza ukunamathela kwi-substrates, ekhokelela ekudibaniseni okungcono kunye nokusebenza kwemveliso yokugqibela.

I-6.Ukuqiniswa kwe-Emulsions kunye nokuSuspensions: I-HEMC isebenza njenge-stabilizer kwi-emulsions kunye nokumiswa, ukuthintela ukuhlukana kwesigaba kunye nokuhlaliswa kweengqungquthela. Le propati inceda ukugcina i-homogeneity kunye nokuzinza kokuqulunqwa, ukuqinisekisa umgangatho wemveliso ohambelanayo.

I-7.Ukuhambelana nezinye izongezo: I-HEMC ihambelana noluhlu olubanzi lwezinye iikhemikhali kunye nezongezo, ezibandakanya i-pigments, i-fillers, kunye ne-rheology modifiers. Inokudityaniswa ngokulula kwiifomyula ezinzima ukufikelela kwiimpawu zokusebenza ezifunwayo.

Usetyenziso lweHydroxy ethyl Methyl Cellulose (HEMC):

I-1. Izinto zokwakha: I-HEMC isetyenziswa kakhulu kwishishini lokwakha njenge-thickener, i-ejenti yokugcina amanzi, kunye ne-binder kwi-samente-based mortars, i-plaster, kunye ne-adhesives tile. Iphucula ukusebenza, ukuncamathela, kunye nokuxhathisa kwe-sag kwezi zixhobo, okukhokelela ekusebenzeni okuphuculweyo kunye nokuqina.

I-2.Iipende kunye neeNgqungquthela: I-HEMC iqeshwe njenge-rheology modifier, i-thickener, kunye ne-stabilizer kwiipeyinti ezisekelwe emanzini, iingubo kunye neenki. Yongeza i-pigment dispersion, inqanda ukudodobala, kwaye iphucula iimpawu zokusetyenziswa kolu luhlu.

I-3.I-Adhesives kunye ne-Sealants: I-HEMC isetyenziselwa ukunamathela kunye ne-sealants ukuphucula amandla okudibanisa, i-tack, kunye nexesha elivulekileyo. Ikwasebenza njenge-ejenti yokuqina kunye ne-rheology modifier, inika i-viscosity efunwayo kunye neempawu zokuhamba kwesicelo.

I-4.IiMveliso zoNyango loMntu: I-HEMC ifumana izicelo kwiimveliso zokhathalelo lomntu ezifana ne-creams, lotions, kunye ne-shampoos njenge-thickener, i-stabilizer, kunye nefilimu yangaphambili. Inika ukuthungwa okunqwenelekayo, ukungaguquguquki, kunye neempawu zerheological kolu lwakhiwo.

I-5.Amayeza: Kwizinto ezixutywayo zamachiza, i-HEMC isebenza njenge-binder, i-disintegrant, kunye ne-ejenti elawulwayo yokukhululwa kwiipilisi, ii-capsules, kunye ne-ointments. I-biocompatibility yayo kunye nokunyibilika kwamanzi kuyenza ilungele ukusetyenziswa komlomo kunye ne-topical.

6.Ishishini lokuTya: Ngelixa ixhaphake kakhulu, iHEMC ikwasetyenziswa kushishino lokutya njengento etyebisayo, isizinzisi, kunye ne-emulsifier kwiimveliso ezithile ezifana neesosi, izinxibo, kunye nezimuncumuncu.

IHydroxy ethyl Methyl Cellulose (HEMC) yipolymer eguquguqukayo enezicelo ezahlukeneyo kumashishini amaninzi. Ukunyibilika kwayo kwamanzi, iipropathi ezityebileyo, amandla okwenza ifilim, kunye nokuhambelana nezinye izongezo zenza ukuba zixabiseke ekwakhiweni, iipeyinti kunye neengubo zokwaleka, izinto zokuncamathelisa, iimveliso zokhathalelo lomntu, amayeza kunye nokwakhiwa kokutya. Njengoko iinzame zophando kunye nophuhliso ziqhubeka, i-HEMC kulindeleke ukuba idlale indima ebalulekileyo kwiinkqubo zanamhlanje zoshishino.
