Ukumba iCarboxymethyl cellulose CMC-Oil

I-Carboxymethyl cellulose CMC-Oil drilling Isithombe Esifakiwe

Incazelo emfushane:

I-Carboxymethylation reaction ingenye yobuchwepheshe be-etherification.Ngemuva kwe-Carboxymethylation ye-cellulose, i-carboxymethyl cellulose (CMC) itholakala.Isixazululo saso samanzi sinemisebenzi yokuqina, ukwenza ifilimu, ukubopha, ukugcinwa kwamanzi, ukuvikelwa kwe-colloidal, i-emulsification nokumiswa.Isetshenziswa kakhulu ezimbonini ze-petroleum, zokudla, zemithi, zendwangu kanye nezokwenza amaphepha.Ingenye ye-cellulose ethers ebaluleke kakhulu.Ngobuchwepheshe bethu besikhathi eside ekuhwebeni kwemikhiqizo yamakhemikhali, ingabe sikunikeza izeluleko zochwepheshe ngemikhiqizo nezixazululo eziklanyelwe injongo yakho ethile.Siyajabula ukukusiza ukuthi ukhethe izinto ezikufanelekelayo.Vele uchofoze ukuze uthole izinhlelo zokusebenza embonini yakho: I-CMC ekudleni, ku-petroleum, ekuphrinteni nasekudayeni, izitsha zobumba, umuthi wokuxubha amazinyo, i-beneficiation entantayo, ibhethri, i-coating, i-putty powder kanye nokwenza amaphepha.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Imodeli ye-CMC yebanga le-Petroleum: CMC - HV;I-CMC-LV ;I-CMC-LVT/LV;I-CMC-HVT
Inamandla aphezulu okulawula ukulahleka kwamanzi, ikakhulukazi isinciphisi esisebenzayo sokulahlekelwa uketshezi.Ngomthamo ophansi, ingakwazi ukulawula ukulahlekelwa kwamanzi ezingeni eliphezulu ngaphandle kokuthinta ezinye izakhiwo zodaka;
Inokumelana kahle nezinga lokushisa kanye nokumelana nosawoti okuhle kakhulu.Ingase ibe nekhono elihle lokunciphisa ukulahlekelwa kwamanzi kanye ne-rheology ethile ngaphansi kokuhlushwa kukasawoti othile.I-viscosity cishe ayishintshile ngemva kokuncibilika emanzini anosawoti.Ifaneleka ngokukhethekile ukumba ogwini kanye nemithombo ejulile;
Ingakwazi ukulawula kahle i-rheology yodaka futhi ine-thixotropy enhle.Ilungele noma yiluphi udaka olusekelwe emanzini emanzini ahlanzekile, emanzini olwandle kanye ne-saturated brine;

CMC-Application In Petroleum

1. Iqhaza le-CMC emkhakheni kawoyela imi kanje:
- I-CMC inganciphisa ukulahleka kwamanzi odongeni lomthombo futhi inciphise ukungena kodaka;
- Ngemva kokwengeza i-CMC odakeni, umshini wokumba ungathola amandla okugunda okuqala aphansi, ukuze udaka lube lula ukukhulula igesi egoqwe kulo, futhi imfucumfucu ingalahlwa ngokushesha emgodini wodaka;
- Njengamanye ama-dispersions amisiwe, udaka lokumba lunesikhathi esithile sokuphila, esingaqiniswa futhi sinwetshwe ngemva kwe-CMC.
2. I-CMC inokusebenza okuhle kakhulu okulandelayo ekusetshenzisweni kwendawo yamafutha:
- Iziqu eziphakeme zokufaka esikhundleni, ukufana okuhle esikhundleni, i-viscosity ephezulu kanye nesilinganiso esiphansi, esingathuthukisa ngempumelelo insizakalo yodaka;
- Ukumelana nomswakama omuhle, ukumelana nosawoti kanye nokumelana ne-alkali, kulungele amanzi ahlanzekile, amanzi olwandle kanye nodaka olusekelwe emanzini olune-brine;
- Ikhekhe lodaka elakhiwe lisezingeni elihle futhi lizinzile, elingakwazi ukusimamisa kahle inhlabathi ethambile
- Ilungele izinhlelo zodaka ezinokulawulwa kokuqukethwe okuqinile okunzima kanye nobubanzi obuhlukahlukene.
