Kev Sib Piv ntawm Cov Khoom Siv Tiv Thaiv Kev Poob Dej ntawm Polyanionic cellulose Tsim Los Ntawm Cov Txheej Txheem Hmoov Thiab Cov Txheej Txheem Slurry

Polyanionic cellulose (PAC) yog ib qho polymer uas yaj tau hauv dej uas tau los ntawm cellulose thiab feem ntau siv ua cov tshuaj ntxiv rau kev tswj kev poob kua hauv cov kua dej uas siv rau hauv kev tshawb nrhiav roj thiab roj av. Ob txoj hauv kev tseem ceeb ntawm kev tsim PAC yog cov txheej txheem ua khob noom cookie thiab cov txheej txheem slurry. Nov yog kev sib piv ntawm cov khoom tiv thaiv kev poob kua ntawm PAC uas tsim los ntawm ob txoj hauv kev no:

1. Cov txheej txheem ua khob noom cookie:
   • Txoj Kev Tsim Khoom: Hauv cov txheej txheem ua khob noom cookie, PAC yog tsim los ntawm kev sib xyaw cellulose nrog alkali, xws li sodium hydroxide, los tsim cov khob noom cookie alkaline. Cov khob noom cookie no tom qab ntawd sib xyaw nrog chloroacetic acid los qhia cov carboxymethyl pawg rau ntawm cellulose backbone, ua rau PAC.
   • Qhov Loj ntawm Cov Khoom Me Me: PAC uas tsim los ntawm cov txheej txheem ua khob noom feem ntau muaj qhov loj ntawm cov khoom me me thiab tej zaum yuav muaj cov agglomerates lossis cov khoom sib sau ua ke ntawm cov khoom me me PAC.
   • Kev Tiv Thaiv Kev Poob Kua: PAC uas tsim los ntawm cov txheej txheem ua khob noom feem ntau ua rau muaj kev tiv thaiv kev poob kua zoo hauv cov kua drilling. Txawm li cas los xij, qhov loj me ntawm cov khoom me me thiab qhov muaj peev xwm ntawm cov agglomerates yuav ua rau cov dej nqus thiab kev sib kis qeeb dua hauv cov kua drilling uas muaj dej, uas yuav cuam tshuam rau kev tswj kev poob kua, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias siab.
2. Cov Txheej Txheem Slurry:
   • Txoj Kev Tsim Khoom: Hauv cov txheej txheem slurry, cellulose yog thawj zaug dispersed hauv dej los ua ib qho slurry, uas tom qab ntawd reacted nrog sodium hydroxide thiab chloroacetic acid los tsim PAC ncaj qha rau hauv cov kua.
   • Qhov Loj ntawm Cov Khoom Me Me: PAC uas tsim los ntawm cov txheej txheem slurry feem ntau muaj qhov loj me me dua thiab sib xyaw ua ke ntau dua hauv cov kua piv rau PAC uas tsim los ntawm cov txheej txheem khob noom cookie.
   • Kev Tiv Thaiv Kev Poob Kua: PAC uas tsim los ntawm cov txheej txheem slurry feem ntau ua rau pom tias muaj kev tiv thaiv kev poob kua zoo heev hauv cov kua drilling. Qhov me me ntawm cov khoom me me thiab kev sib kis sib npaug ua rau muaj kev nqus dej sai dua thiab kev sib kis hauv cov kua drilling uas yog dej, ua rau muaj kev tswj hwm kev poob kua zoo dua, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej drilling nyuaj.

ob qho tib si PAC tsim los ntawm cov txheej txheem ua khob noom cookie thiab PAC tsim los ntawm cov txheej txheem slurry tuaj yeem muab kev tiv thaiv kev poob kua dej zoo hauv cov kua drilling. Txawm li cas los xij, PAC tsim los ntawm cov txheej txheem slurry yuav muab qee qhov zoo, xws li kev ua kom dej thiab kev sib kis sai dua, ua rau muaj kev tswj hwm kev poob kua dej zoo dua, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias siab thiab siab siab drilling ib puag ncig. Thaum kawg, kev xaiv ntawm ob txoj kev tsim khoom no yuav nyob ntawm qhov yuav tsum tau ua haujlwm tshwj xeeb, kev txiav txim siab txog tus nqi, thiab lwm yam tseem ceeb rau kev siv cov kua drilling.
