1.Ukucaciswa Kwekhemikhali

2.Imikhiqizo Amabanga

3.I-Hydroxyethyl Cellulose (HEC) Izicelo:

Kupende osuselwe emanzini, udlala indima yokuhlakaza nokuvikela ama-gel, uthuthukise ukuzinza kokusabela kwesistimu ye-agglomerate, uqinisekisa ukusatshalaliswa okulinganayo kwe-pigment nokugxusha, nokuhlinzeka ngomphumela wokujiya, ukuthuthukisa uketshezi.

Ekubholeni uwoyela, kusetshenziswa njenge-stabilizer kanye ne-ejenti yokuqina, i-ejenti yokugcoba yokubhoboza kahle, ukuqedela nokuhlanganisa ukuze kunikeze udaka uketshezi oluhle nokuzinza.

Ekwakhiweni, i-HEC ingasetshenziswa njenge-ejenti yokuqina kanye ne-ejenti ehlangene ukuze kuthuthukiswe uketshezi nokusebenza kahle, ukukhulisa amandla okuqala okugaya futhi ugweme ukuqhekeka.

Ekuxubheni nasekuhlanganiseni usimende, ngokusobala kungase kukhuphule ukubamba kwamanzi namandla okuhambisana.

Emakhemikhalini asetshenziswa nsuku zonke afana nomuthi wokuxubha anika indawo enhle ngokomzimba namakhemikhali, ayenze ibe muhle, igcinwe isikhathi eside, yome futhi igcwale.

Emkhakheni wezimonyo, ingakhuphula ukuminyana kwezinto ezibonakalayo, ingeze ukuthambisa nokushelela.

Ngaphandle kwalokho, inokusebenza okubanzi ku-inki, ukudaya kwezindwangu & ukuphrinta, ukwenza iphepha, imithi, ukudla, ezolimo njll.

4.I-Hydroxyethyl Cellulose (HEC) Ukusebenzisa indlela:

Indlela Yokuqala: Faka Ngokuqondile

1. Thela amanzi ahlanzekile ebhakedeni elihlinzekwe nge-stirrer.

2. Ekuqaleni gudluza kancane, usakaze ngokulinganayo i-HEC esixazululweni.

3. Govuza kuze kube yilapho wonke amagranule e-HEC esemanziswe ngokugcwele.

4. Okokuqala faka i-anti-mildew ejenti, bese wengeza izithasiselo ezifana ne-pigment, i-disperser njll.

5. Qhubeka ugqugquzela kuze kuhlakazwe yonke i-HEC nezithasiselo (i-viscosity esixazululweni ngokusobala iyakhula), bese ufaka ezinye izithako ukuze usabele.

Indlela Yesibili: Lungiselela Utshwala Bomama Ukuze Usetshenziswe

Okokuqala lungisa ugologo owugqinsi, bese ubufaka emkhiqizweni. Inzuzo yendlela ukuguquguquka, utshwala bungafakwa ngokuqondile emkhiqizweni. Inqubo kanye nendlela yokusebenzisa iyafana no-1-4 endleleni (Ⅰ), qinisa uze uncibilike ngokuphelele ube yingxube enamathelayo futhi ewugqinsi bese ufaka i-anti-mildew otshwaleni kamama ngokushesha okukhulu.

Indlela Yesithathu: Lungiselela Okufana Ne-Gruel Okuzosetshenziswa

Njengoba izinyibilikisi zemvelo zingezona izincibilikisi ze-HEC, zingasetshenziselwa ukulungisa izinto ezifana ne-gruel.Okusetshenziswa kakhulu i-ethylene glycol, i-propylene glycol kanye ne-ejenti eyenza ifilimu (i-hexamethylene-glycol, i-diethyl glycol butyl acetate njll.) amanzi, futhi ingalungiswa kanye nezincibilikisi eziphilayo zibe izinto ezifana ne-gruel.

Izinto ezifana ne-Gruel zingafakwa emkhiqizweni ngoba i-HEC entweni efana ne-gruel isicwiliswe ngokuphelele futhi yavuvukala, ifakwa emkhiqizweni iyancibilika ngokushesha futhi ikhuthaze ukujiya, kodwa qhubeka ugqugquzela ize incibilike ngokuphelele.

Ngokuvamile into efana ne-gruel itholakala ngokuxuba i-organic solvent noma amanzi aneqhwa ne-HEC ngengxenye engu-6:1, ngemva kwemizuzu engu-5-30 i-HEC i-hydrolyzes futhi ikhukhumale. Le ndlela ayimukelwa ehlobo ngenxa yesimo sezulu esishisayo.

5.Umhlahlandlela Wesicelo Wezimboni Zopende

Imiphumela Yokuqina Okuphezulu

IHydroxyethy Cellulose ihlinzeka ngopende be-latex ikakhulukazi opende be-PVA abaphezulu ngokusebenza okuhle kakhulu kokunamathela.Lapho upende unamathisele obukhulu, akukho flocculation ezokwenzeka.

IHydroxyethy Cellulose inemiphumela ephezulu yokujiya, ngakho-ke inganciphisa umthamo, ithuthukise ukusebenza kahle kwezindleko zokwakheka, futhi ithuthukise ukumelana nokuwashwa kopende.

Izakhiwo ezinhle kakhulu ze-Rheological

Isixazululo esinamanzi seHydroxyethy Cellulose siwuhlelo olungezona olwase-Newtonian, futhi izakhiwo zesixazululo zibizwa ngokuthi i-thixotropy.

Esimeni esimile, ngemva kokuba umkhiqizo usuhlakazwe ngokuphelele, uhlelo lokumboza lungagcina isimo esihle kakhulu sokuqina kanye nesimo sokuvula.

Esimeni sokulahla, isistimu ingagcina i-viscosity emaphakathi, yenza imikhiqizo ibe ne-fluidity enhle kakhulu, hhayi i-spatter.

Ngesikhathi sokuxubha kanye ne-roller coating, umkhiqizo kulula ukusabalalisa ku-substrate, ngakho-ke kulula ukwakhiwa, futhi okwamanje, unokumelana okuhle kwe-spatter.

Ekugcineni, ngemva kokuqedwa koqweqwe lukapende, i-viscosity yesistimu izobuyiselwa ngokushesha, futhi upende uzokhiqiza ngokushesha impahla enyakazayo.

Ukuhlakazeka kanye ne-Solubility

I-Hydroxyethy Cellulose yonke iphathwa ngokuqedwa okubambezelekile, futhi esimweni sokwengeza i-powder eyomile, ingavimbela ngokuphumelelayo i-caking futhi iqinisekise ukuthi i-hydration iqala ngemva kokuhlakazwa okwanele kwe-HEC powder.

I-Hydroxyethy Cellulose ngemuva kokwelashwa okufanele kwendawo ingalawula kahle izinga lokuqedwa kanye nezinga lokwenyuka kwe-viscosity lomkhiqizo.

Ukuqina Kwesitoreji

I-Hydroxyethy Cellulose inokusebenza okuhle kokumelana nesikhutha, inikeza isikhathi esanele sokulondoloza upende, futhi ivimbele ngempumelelo ukugcwala kombala nezigcwalisi.a
