Polyanionic cellulose

Polyanionic cellulose (PAC) ndi chochokera m'madzi chosungunuka cha cellulose chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makamaka pobowola mafuta ndi gasi. Nayi chithunzithunzi cha cellulose ya polyanionic:

1. Mapangidwe: Ma cellulose a Polyanionic amachokera ku cellulose, polima yachilengedwe yomwe imapezeka muzomera, kudzera mukusintha kwamankhwala. Magulu a carboxymethyl amalowetsedwa pamsana wa cellulose, ndikuupatsa mphamvu ya anionic (yopanda pake).

2. Kachitidwe:

• Viscosifier: PAC imagwiritsidwa ntchito ngati viscosifier mumadzi obowola otengera madzi. Amapereka mamasukidwe akayendedwe amadzimadzi, kuwongolera luso lake loyimitsa ndi kunyamula zodulidwa zoboola pamwamba.
• Fluid Loss Control: PAC imapanga keke yopyapyala yopyapyala pakhoma la borehole, imachepetsa kutayika kwamadzi kuti ipangike ndikusunga bata pachitsime.
• Rheology Modifier: PAC imakhudza kayendetsedwe ka kayendetsedwe kake komanso mawonekedwe amadzimadzi obowola, kupititsa patsogolo kuyimitsidwa kwa zolimba ndikuchepetsa kukhazikika.

3. Mapulogalamu:

• Kubowola Mafuta ndi Gasi: PAC ndiyowonjezera pamadzi obowola opangidwa ndi madzi omwe amagwiritsidwa ntchito pofufuza ndi kupanga mafuta ndi gasi. Imathandiza kulamulira mamasukidwe akayendedwe, kutayika kwamadzimadzi, ndi rheology, kuwonetsetsa kuti kubowola koyenera komanso kukhazikika kwa chitsime.
• Ntchito yomanga: PAC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi m'mapangidwe a simenti monga ma grouts, slurries, ndi matope omwe amagwiritsidwa ntchito pomanga.
• Mankhwala: Pakupanga mankhwala, PAC imagwira ntchito ngati binder, disintegrant, and controlled-rease agent mu mapiritsi ndi makapisozi.

4. Katundu:

• Kusungunuka kwamadzi: PAC imasungunuka mosavuta m'madzi, kulola kulowetsedwa mosavuta m'madzi amadzimadzi popanda kufunikira kwa zosungunulira zowonjezera kapena zotayira.
• Kukhazikika Kwapamwamba: PAC imawonetsa kukhazikika kwamafuta ndi mankhwala, kusunga mawonekedwe ake pamitundu yosiyanasiyana ya kutentha ndi pH.
• Kulekerera Kwamchere: PAC ikuwonetsa kuyanjana kwabwino ndi kuchuluka kwa mchere ndi ma brines omwe nthawi zambiri amakumana nawo m'malo opangira mafuta.
• Kuwonongeka kwa Biodegradability: PAC idatengedwa kuchokera kuzinthu zongowonjezedwanso kuchokera ku zomera ndipo imatha kuwonongeka ndi chilengedwe, zomwe zimapangitsa kuti ikhale yogwirizana ndi chilengedwe.

5. Ubwino ndi Mafotokozedwe:

• Zogulitsa za PAC zimapezeka m'magiredi osiyanasiyana komanso mawonekedwe ogwirizana ndi magwiritsidwe ake ndi magwiridwe antchito.
• Njira zowongolera zabwino zimatsimikizira kusasinthika komanso kutsata miyezo yamakampani, kuphatikiza mafotokozedwe a API (American Petroleum Institute) pakubowola zowonjezera zamadzimadzi.

Mwachidule, polyanionic cellulose ndi chowonjezera chosinthika komanso chothandiza chokhala ndi viscosifying, kuwongolera kutayika kwamadzimadzi, komanso ma rheological properties, zomwe zimapangitsa kuti zikhale zofunikira pakugwiritsa ntchito mafakitale osiyanasiyana, makamaka pobowola mafuta ndi gasi. Kudalirika kwake, magwiridwe antchito, komanso kuyanjana kwachilengedwe kumathandizira kuti igwiritsidwe ntchito kwambiri m'malo ovuta kubowola.
