IHydroxYethyl Cellulose (HEC) iyinhlangano ebalulekile yeselula ebonakalayo, esetshenziswa kakhulu embonini yokupenda njengomuntu omkhulu, i-stabilizer kanye ne-Rheology modifier. Kungathuthukisa uketshezi nokuqina kopende futhi kuthuthukise izakhiwo zayo zokwakha amafilimu.
1. Izakhiwo nemisebenzi ye-hydroxyethyl cellulose
1.1 Izakhiwo eziyisisekelo
I-Hydroxyyethyl celtulose iyi-polymer engenamanzi eyenziwe ngamanzi eyenziwe ukwethula amaqembu we-hydroxyethyl e-cellulose. Izici zalo zifaka:
I-Solubinity yamanzi: incane kalula emanzini ukuze kwakheke obala ku-Milky White Solution.
Ukulawulwa kwe-Viscosity: I-viscosity yesixazululo ingalawulwa ngokulungisa ukugxila kwayo.
Ukuqina kwe-PH: ezinzile ngaphezu kobubanzi be-PH.
I-Biodegradeabilibility: Imvelo Imvelo.
1.2 Imisebenzi
Ngopende, imisebenzi esemqoka ye-hydroxyethyl cellulose ifaka:
Ukuqina
Ukuzinza: Vikela ukufundwa kwe-pigment futhi uthuthukise ukuqina kwesitoreji.
Ukulawulwa Kwe-Rheelogy: Thuthukisa izakhiwo zesimbozo sopende futhi ulawule uketshezi futhi ulwele upende ngesikhathi sokwakha.
2. Izinyathelo zokwengeza i-hydroxyethyl cellulose
2.1 Ukulungiselela
Ekukhiqizeni okunama-coating, amalungiselelo alandelayo ayadingeka ukuze wengeze i-hydroxyethyl cellulose:
Ukulungiselela Okubonakalayo Okubonakalayo: Khetha uhlobo olufanele kanye nokucaciswa kwe-hydroxyethyl cellulose (njengamazinga ahlukene wokufaka esikhundleni kanye namabanga okubona).
I-Disolving Medium: Lungiselela okuphakathi kokuqeda i-hydroxyethyl cellulose, imvamisa amanzi noma ikhambi elinamanzi.
2.2 Inqubo Yokuchithwa
Ukusakazwa: fafaza kancane kancane i-hydroxyethyl cellulose kumanzi abandayo ashukumisayo. Ukugwema ukulondolozwa, i-cellulose ingahlelwa ngenani elithile le-glycerol noma enye i-ejenti yokulwa nokwakheka.
Ukuvuselela: Qhubeka uvuse ukukhuthaza ukuhlakazwa kweselula emanzini. Ijubane elishukumisayo kufanele lisheshe ngokwanele ukugwema ukwakheka kwezigaxa, kepha hhayi phezulu kakhulu ukugwema ukwethula umoya omningi.
Ukuvuvukala: Vumela i-cellulose ukuvuvukala ngokuphelele emanzini. Imvamisa kuthatha imizuzu engama-30 kuye emahoreni ambalwa, kuya ngohlobo nokucaciswa kwe-cellulose.
Ukushisa (Ngokuzithandela): Ngeminye izinhlobo zamaselula, amanzi angashisa ngokulinganisela (imvamisa hhayi ngaphezulu kuka-50 ° C) ukusheshisa inqubo yokuqothula.
Ukuchitheka: Qhubeka ngokuvusa kuze kube yilapho i-cellulose ichithwa ngokuphelele futhi kwakhiwa isixazululo somfaniswano. Isixazululo esincibilikisiwe kufanele sibe sobala noma siguqulwe, ngaphandle kwezinhlayiya ezisobala noma iselula engaphezulu.
2.3 Faka ku-coating
Ukulungiswa kwesisombululo esixutshwe ngaphambilini Lokhu kuqinisekisa ukuthi i-cellulose isatshalaliswa ngokulinganayo kwi-coating.
Ukungezwa kancane kancane: Ngeza kancane kancane isixazululo se-hydroxyethyl cellulose sangaphambilini esixukwini esixubile esisezingeni eliphakeme lokuhlanganisa. Gcina uvuse ngokulinganayo ukuvikela ukwakheka kwama-clots.
Ukuxuba: Qhubeka ngokuvusa inkanuko kuyo yonke inqubo yokungezwa nangemva kokuqinisekisa ukuthi i-cellulose isatshalaliswa ngokulinganayo ekuhlanganisweni.
Ukuhlola nokulungiswa: Hlola i-viscosity, ushukela kanye nezinye izakhiwo ezibalulekile ze-coating, bese ulungisa inani leselula noma ingxenye yezinye izakhi zenhlanganisela uma kunesidingo sokuthola ukusebenza okulindelekile.
3. Ukuqapha
3.1 Vimbela uCapking
Isivinini sokufafaza: fafaza i-hydroxyethyl cellulose kancane ukugwema ukungezwa ngokweqile ngasikhathi sinye.
Kuvuselelwa: gcina ijubane elishukumisayo elishukumisayo ukuze ugweme ukukheka.
3.2 Ukulawulwa kokushisa
Gwema izinga lokushisa eliphakeme: izinga lokushisa eliphakeme lingadala ukonakaliswa kwe-hydroxyethyl cellulose, imvamisa elawulwa ngaphansi kuka-50 ° C.
Ukushisa okulinganiselayo: Ukushisa okulinganiselayo kungasheshisa ukuqedwa, kepha unake ukulawulwa kokushisa.
3.3 PH Control
Imvelo engathathi hlangothi: I-Hydroxyyethyl cellulose isitebelelo ngokwemvelo engathathi hlangothi noma kancane, futhi ukweqisa ph kungathinta ukuqina nokusebenza kwayo.
3.4 Isitoreji Solution
Vimbela ukungcoliswa kwamagciwane: Isixazululo sihlaselwa kalula ama-microorganisms futhi sidinga ukungezwa ngezivikelo noma ezigcinwe emazingeni okushisa aphansi.
Impilo yeshelufu: Kunconywa ukuyisebenzisa ngokushesha okukhulu ngemuva kokulungiselela ukuqinisekisa ukusebenza kahle.
4. Amacala wohlelo lokusebenza
4.1 Intellior Wall Paint
E-Interior Wall Latex Paint, i-Hydroxyyethyl celtule
4.2 Upende wangaphandle wangaphandle
Kupende wangaphandle odongeni, engeza i-hydroxyethyl celtule
4.3 Upende wezinkuni osuselwa emanzini
Ependweni wezinkuni asuselwa emanzini, i-hydroxyyethyl celtule
Njengomkhulu osindayo kanye ne-rheology modifier in Coatings, i-hydroxyyethyl cellulose inomphumela omkhulu wokuthuthukisa ukusebenza. Ngesikhathi senqubo yokwengeza, kufanele kubhekwe ekuxazululeni kwayo, ukufakwa kwezengezo kanye nezimo zezemvelo ukugwema ukuhlangana nokuwohloka. Kuzinhlelo zokusebenza ezisebenzayo, ikhwalithi nokusebenza kwezimbozo kungathuthukiswa ngempumelelo ngokulingana okunengqondo nezindlela zokusebenzisa.
