IHydroxyethylcellulose (HEC) iyipolymer encibilika emanzini esetshenziswa kabanzi ezimbonini ezahlukahlukene ezihlanganisa ezokwakha, ezokudla, ezemithi kanye nemikhiqizo yokunakekela umuntu. Kuyinto engokwemvelo, ebolayo etholakala ku-cellulose, i-carbohydrate etholakala ezindongeni zamangqamuzana ezitshalo. Emigqeni yamatshe yemvelo, i-HEC idlala indima ebalulekile ekuthuthukiseni ukusebenza kanye nezakhiwo zobuhle zokugqoka.
Izembatho zamatshe zemvelo zisetshenziselwa ukuvikela nokuthuthukisa ukubukeka kwezindawo zamatshe zemvelo njengemabula, i-granite kanye ne-limestone. Lezi zinhlobonhlobo zinikeza ungqimba lwesivikelo esimweni sezulu, ukugqwala, ukubola kanye nokunwaya. Bangakwazi futhi ukuthuthukisa umbala, ukukhazimula nokuthungwa kwetshe, ngaleyo ndlela kuthuthukise ubuhle balo bemvelo.
Kodwa-ke, izigqoko zamatshe zemvelo zibhekana nezinselele eziningana ngokufaka isicelo, ukunamathela nokusebenza. Ukugqoka kufanele kunamathele ngokuqinile endaweni yetshe ngaphandle kokulimaza itshe noma ukuphazamisa ukuthungwa kwayo kwemvelo. Kufanele futhi amelane nemisebe ye-UV nezinye izingcindezi zemvelo ezingadala ukuwohloka noma ukuguquguquka ngokuhamba kwesikhathi. Ukwengeza, upende kufanele kube lula ukuwufaka, wome ngokushesha, futhi ungajwayele ukuqhekeka noma ukuxebuka.
Ukuze kuxazululwe lezi zinselele, izigqoko zamatshe zemvelo ngokuvamile zihlanganisa izithasiselo ezihlukahlukene kanye nama-fillers ukuze kuthuthukiswe izakhiwo zabo. I-HEC iyisengezo esinjalo esivame ukusetshenziswa kulezi zingubo ngenxa yezakhiwo zayo eziyingqayizivele.
Indima eyinhloko ye-HEC ekugqokeni kwamatshe emvelo ukusebenza njenge-thickener, binder kanye ne-rheology modifier. Ama-molecule e-HEC anezakhiwo ezinde eziwumugqa ezimunca amanzi futhi akhe into efana nejeli. Le nto efana nejeli ishubisa amafomula kapende, iwenze abukeke kakhudlwana futhi kube lula ukuwasebenzisa. Ngaphezu kwalokho, into efana ne-gel ingahlinzeka ngokuhlakazeka okuzinzile nokufana kwezingxenye zokugqoka, ukuvimbela ukuxazulula noma ukuhlukana.
I-HEC isebenza njengesibopho sokuthuthukisa ukunamathela kokugqoka endaweni yamatshe. Ama-molecule e-HEC angakwazi ukuhlangana nezindawo zamatshe kanye nezingxenye zokumboza ukuze akhe izibopho eziqinile nezihlala isikhathi eside. Lesi sibopho simelana nokugunda, ukugoqa noma ukuhlukaniswa ngaphansi kwengcindezi, ukuqinisekisa ukunamathela kwesikhathi eside nokuvikelwa kwendawo yetshe.
I-HEC iphinde isebenze njenge-rheology modifier, elawula ukugeleza kanye ne-viscosity ye-coating. Ngokulungisa inani kanye nohlobo lwe-HEC, i-viscosity kanye ne-thixotropy ye-coating ingalungiswa ukuze ivumelane nendlela yokufaka isicelo kanye nokusebenza okufunayo. Thixotropy iyindawo kapende ogeleza kalula uma ungaphansi kwengcindezi yokugunda, njengalapho uxutshwa noma ufaka isicelo, kodwa ujiya ngokushesha lapho kususwa ukucindezeleka kokugunda. Lesi sakhiwo sithuthukisa ukusabalala kanye nokumbozwa kwengubo ngenkathi kunciphisa ukuconsa noma ukugoqa.
Ngaphezu kwendima yayo yokusebenza, i-HEC ingathuthukisa izakhiwo zobuhle zezingubo zamatshe zemvelo. I-HEC ingathuthukisa umbala, ukukhanya nokuthungwa kwe-coating ngokwenza ifilimu ebushelelezi neyunifomu endaweni yamatshe. Ifilimu iphinde inikeze izinga elithile lamanzi nokumelana namabala, ukuvimbela amanzi noma olunye uketshezi ukuthi lungaguquki noma lungene endaweni yetshe.
I-HEC futhi iyimpahla yemvelo futhi ehambisana nemvelo ephephile ukuthi ingayisebenzisa futhi ilahlwe. Iyakwazi ukubola futhi ayikhiqizi imikhiqizo eyingozi noma izinto ezikhishwayo ngesikhathi sokukhiqiza noma ukusetshenziswa.
Kafushane, i-hydroxyethyl cellulose (HEC) idlala indima ebalulekile ngokuthuthukisa ukusebenza nobuhle bezingubo zamatshe zemvelo. I-HEC isebenza njenge-thickener, binder kanye ne-rheology modifier, ithuthukisa i-viscosity, ukunamathela nokugeleza kwezingubo. I-HEC ingabuye ithuthukise umbala, isicwebezelisi kanye nokuthungwa kwezingubo zokugqoka futhi inikeze izinga lamanzi nokumelana namabala. Ngaphezu kwalokho, i-HEC iyinto engokwemvelo, ebolayo ephephile futhi enobungani nemvelo.
