Ibanga lokuhlanza i-HEMC

Ibanga lokuhlanza i-HEMC I-Hydroxyethyl methylcellulose iyimpushana emhlophe engenaphunga, engenabuthi, engancibilika emanzini abandayo ukuze yakhe isisombululo se-viscous esisobala. Inezici zokuqina, ukubopha, ukuhlakazeka, i-emulsification, ukwakheka kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ongaphezulu, ukugcinwa komswakama kanye ne-colloid evikelayo. Njengoba isixazululo esinamanzi sinomsebenzi osebenzayo ongaphezulu, singasetshenziswa njenge-colloid evikelayo, i-emulsifier ne-dispersant. Isixazululo samanzi se-Hydroxyethyl methyl cellulose sine-hydrophilicity enhle futhi iyi-ejenti esebenza kahle yokugcina amanzi.

Ibanga lokuhlanza i-HEMC I-Hydroxyethyl Methyl Cellulose yaziwa ngokuthi i-Methyl Hydroxyethyl Cellulose(MHEC), Ilungiswa ngokwethula izinto ezifakwa ethylene oxide (MS 0.3–0.4) ku-methyl cellulose (MC). Ukubekezelela usawoti wayo kungcono kunama-polymers angashintshiwe. Izinga lokushisa lejeli le-methyl cellulose nalo liphakeme kunalelo le-MC.

I-HEMC yebanga lokuhlanza iyimpushana emhlophe noma ephuzi kancane, futhi ayinaphunga, ayinambitheki futhi ayinabuthi. Ingancibilika emanzini abandayo nasezincibilikisini eziphilayo ukuze kwakhe isixazululo se-viscous esisobala. Uketshezi lwamanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, nokuzinza okuqinile, futhi ukuchithwa kwawo emanzini akuthintwa i-pH. Inomphumela wokujiya nokunqanda ukuqhwa kuma-shampoos namajeli okugeza, futhi inokugcina amanzi kanye nezakhiwo ezinhle zokwenza ifilimu zezinwele nesikhumba. Ngokukhula okukhulu kwezinto zokusetshenziswa eziyisisekelo, ukusetshenziswa kwe-cellulose (antifreeze thickener) kuma-shampoos namajeli okugeza kunganciphisa kakhulu izindleko futhi kuzuze imiphumela oyifunayo.

 

Izici Zomkhiqizo:

1. Ukuncibilika: kuncibilika emanzini nakwezinye izincibilikisi eziphilayo. I-HEMC ingancibilika emanzini abandayo. Ukugxila kwayo okuphezulu kunqunywa kuphela yi-viscosity. I-solubility ishintsha nge-viscosity. I-viscosity ephansi, i-solubility enkulu.

2. Ukumelana nosawoti: Imikhiqizo ye-HEMC i-non-ionic cellulose ethers hhayi i-polyelectrolyte. Ngakho-ke, lapho usawoti wensimbi noma ama-electrolyte ephilayo ekhona, azinzile kuzixazululo ezinamanzi, kodwa ukwengeza ngokweqile kwama-electrolyte kungabangela ama-gel kanye nemvula.

3. Umsebenzi ongaphezulu: Njengoba isixazululo esinamanzi sinomsebenzi ongaphezulu, singasetshenziswa njenge-agent evikelayo ye-colloidal, i-emulsifier ne-dispersant.

4. Ijeli eshisayo: Uma isixazululo esinamanzi somkhiqizo we-HEMC sishiselwa ekushiseni okuthile, siba yi-opaque, ama-gel, kanye nemvula, kodwa lapho sipholile ngokuqhubekayo, sibuyela esimweni sokuqala sesixazululo, futhi le gel kanye nemvula kwenzeka. ikakhulukazi kuncike ezintweni zokugcoba, izinsiza zokumisa, ama-colloid okuzivikela, ama-emulsifiers nokunye.

5. I-Metabolic Inertness kanye nephunga eliphansi kanye nephunga elimnandi: Ngenxa yokuthi i-HEMC ngeke igaywe futhi inephunga eliphansi kanye nephunga elimnandi, isetshenziswa kakhulu ekudleni nasemithini.

6. Ukumelana nesikhutha: I-HEMC inekhono elihle lokulwa nesikhunta kanye nokuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.

7. Ukuzinza kwe-PH: I-viscosity yesisombululo se-aqueous somkhiqizo we-HEMC ayithintwa neze i-asidi noma i-alkali, futhi inani le-PH lizinzile ngokuqhathaniswa phakathi kwebanga elingu-3.0-11.0.

Uhla lwesicelo se-cellulose yansuku zonke yamakhemikhali HEMC:

Isetshenziswa ku-shampoo, ukugeza umzimba, okokuhlanza ubuso, okokugcoba, ukhilimu, ijeli, i-toner, i-conditioner, imikhiqizo yesitayela, umuthi wokuxubha, i-mouthwash, amanzi amabhamuza wethoyizi.

 

Indima yeokokugezaI-cellulose yezinga HEMC:

Ezinhlelo zokusebenza zezimonyo, isetshenziselwa ikakhulukazi ukuqina kwezimonyo, ukugwebu, i-emulsification ezinzile, ukuhlakazeka, ukunamathela, ukwakheka kwefilimu kanye nokwenza ngcono ukusebenza kokugcinwa kwamanzi, imikhiqizo ye-viscosity ephezulu isetshenziswa njengokuqina, futhi imikhiqizo ye-viscosity ephansi isetshenziselwa ukumiswa kanye ukuhlakazeka. Ukwakhiwa kwefilimu.

 

Pukupakisha, ukulahlwa kanye nokugcinwa

(1) Ipakishwe esikhwameni se-polyethylene esiyinhlanganisela yephepha-plastiki noma isikhwama sephepha, 25KG/isikhwama;

(2) Gcina umoya ugeleza endaweni yokugcina, gwema ukukhanya kwelanga, futhi ugweme imithombo yomlilo;

(3) Ngenxa yokuthi i-hydroxyethyl methyl cellulose HEMC i-hygroscopic, akufanele ivezwe emoyeni. Imikhiqizo engasetshenziswanga kufanele ivalwe futhi igcinwe, futhi ivikelwe emswakama.
