I-Hydroxy Ethyl Cellulose (HEC) - ukugaya amafutha

I-Hydroxyethyl cellulose (HEC) iyi-polymer encibilika emanzini etholakala ku-cellulose, esetshenziswa kabanzi njenge-rheology modifier kanye ne-ejenti yokulawula ukulahlekelwa uketshezi emisebenzini yokumba uwoyela.

Ngesikhathi sokumba uwoyela, uketshezi lokumba lusetshenziselwa ukugcoba i-drill bit, ukuthwala ama-drill cuttings phezulu, nokulawula ingcindezi emthonjeni. Uketshezi lokumba lusiza futhi ukuzinzisa umthombo womthombo futhi kuvimbele ukulimala kokwakheka.

I-HEC yengezwe emanzini okumba ukuze kwandiswe i-viscosity futhi ilawule izakhiwo zokugeleza kwamanzi. Kungasiza ukumisa i-drill cuttings futhi kuvimbele ukuzinza, kuyilapho futhi inikeza ukulawula okuhle kokulahlekelwa uketshezi ukuze kugcinwe ubuqotho bomthombo. I-HEC ingasetshenziswa futhi njenge-lubricant kanye nesihlungi sekhekhe lesihlungi, ukuthuthukisa ukusebenza kahle nokusebenza kwenqubo yokumba.

Enye yezinzuzo ze-HEC ekubholeni uwoyela ukuzinza kwayo emazingeni okushisa aphezulu kanye nezimo zokucindezela okukhulu. I-HEC ingagcina izakhiwo zayo ze-rheological kanye nokusebenza kokulawula ukulahlekelwa uketshezi ezinhlobonhlobo zamazinga okushisa nezingcindezi, okuyenza ifanelekele ukusetshenziswa ezindaweni zokumba eziyinselele.

I-HEC iphinde ihambisane nezinye izinto ezisetshenziselwa uketshezi lokumba, njengobumba, ama-polymers, nosawoti, futhi ingafakwa kalula ekubunjweni. Ubuthi bayo obuphansi kanye nokubola kwayo kuyenza ivumelane nemvelo futhi iphephe ukusetshenziswa emisebenzini yokumba uwoyela.

Sekukonke, i-HEC iyi-polymer eguquguqukayo enganikeza ukulawula okusebenzayo kwe-rheological kanye nokulawulwa kokulahlekelwa uketshezi kuketshezi lokumba uwoyela. Izakhiwo zayo eziyingqayizivele nokuhambisana nezinye izinto zenza kube ukukhetha okudumile kokusebenza kokumba ezindaweni eziningi.
