Polyanionic selile (PAC)
Polyanionic selulose (PAC) ni amazi ya elegitoronike ya selile yamashanyarazi yateguwe noguhindura imiti ya selile naturel.Nibintu byingenzi byamazi ya elegitoronike ya ether.Ubusanzwe ikoreshwa nkumunyu wa sodium kandi ikoreshwa cyane mugucukura amavuta, cyane cyane amariba yamazi yumunyu no gucukura amavuta yo hanze.
PAC-Gusaba Muri peteroli
1. Imikorere ya PAC na CMC mu murima wa peteroli niyi ikurikira:
- Icyondo kirimo PAC na CMC kirashobora gutuma urukuta rw'iriba ruba ruto kandi rukomeye rwo kuyungurura kandi rufite amazi make kandi bikagabanya gutakaza amazi;
- Nyuma yo kongeramo PAC na CMC mucyondo, uruganda rucukura rushobora kubona imbaraga nkeya zogosha, bigatuma ibyondo byoroha kurekura gaze yapfunyitse, kandi bikajugunya vuba imyanda iri mu rwobo;
- Kimwe nandi masoko yahagaritswe, gucukura ibyondo bifite igihe runaka cyo kubaho, gishobora gutekerezwa no kwagurwa wongeyeho PAC na CMC.
2. PAC na CMC bafite imikorere myiza ikurikira mugukoresha peteroli:
- Urwego rwo hejuru rwo gusimburwa, uburinganire bwiza bwo gusimburwa, ubukonje bwinshi hamwe na dosiye nkeya, kuzamura neza serivisi zibyondo;
- Kurwanya ubuhehere bwiza, kurwanya umunyu no kurwanya alkali, bikwiranye n’amazi meza, amazi yo mu nyanja hamwe n’ibyondo byuzuye amazi yuzuye;
- Agatsima k'ibyondo kakozwe ni keza kandi gahamye, gashobora guhagarika neza imiterere yubutaka bworoshye kandi bikarinda urukuta rwa shitingi;
- Irakwiriye sisitemu y'ibyondo igoye kugenzura ibintu bigoye hamwe no gutandukanya ibintu byinshi.
3. Ibiranga ikoreshwa rya PAC na CMC mugucukura peteroli:
- Ifite ubushobozi bwo kugenzura amazi menshi, cyane cyane kugabanya gutakaza amazi.Hamwe na dosiye nkeya, irashobora kugenzura igihombo cyamazi murwego rwo hejuru itagize ingaruka kubindi byondo;
- Ifite ubushyuhe bwiza kandi irwanya umunyu mwiza.Irashobora kugira ubushobozi bwiza bwo kugabanya amazi hamwe na rheologiya imwe murwego rwumunyu.Ubukonje burahinduka hafi yo gushonga mumazi yumunyu.Irakwiriye cyane cyane gucukura ku nkombe n'amariba maremare;
- Irashobora kugenzura neza rheologiya yicyondo kandi ifite thixotropy nziza.Irakwiriye ibyondo byose bishingiye kumazi mumazi meza, amazi yinyanja hamwe na brine yuzuye;
- Byongeye kandi, PAC ikoreshwa nk'isima ya sima kugirango irinde amazi kwinjira mu byobo no kuvunika;
.Iyo ikoreshejwe muburyo buke bwo gushiramo imbaraga, kuyungurura gukanda nibyiza cyane.
