Nws cov khoom zoo ib yam li methyl cellulose, tab sis vim muaj hydroxyethyl cellulose, nws yooj yim dua rau yaj hauv dej, cov tshuaj sib xyaw nrog ntsev ntau dua, thiab muaj qhov kub siab dua coagulation.
03. Carboxymethyl cellulose
1. Siv nyob rau hauv cov roj thiab cov nkev drilling, zoo khawb thiab lwm yam dej num
① CMC-muaj av nkos tuaj yeem ua rau cov phab ntsa zoo tsim cov ncuav mog qab zib nyias thiab ruaj khov nrog cov permeability tsawg, txo cov dej tsis zoo.
② Tom qab ntxiv CMC rau cov av nkos, cov pob zeb drilling tuaj yeem tau txais qhov qis qis qis qis, kom cov av nkos tau yooj yim tso cov roj ntim rau hauv nws, thiab tib lub sijhawm, cov khib nyiab tuaj yeem muab pov tseg sai sai hauv qhov av nkos.
③ Drilling av nkos, zoo ib yam li lwm yam kev ncua thiab kev sib cais, muaj lub neej txee. Ntxiv CMC tuaj yeem ua kom ruaj khov thiab ua kom lub neej ntev.
④ Cov av nkos uas muaj CMC tsis tshua muaj kev cuam tshuam los ntawm pwm, yog li nws yuav tsum tswj hwm tus nqi pH siab, thiab nws tsis tas yuav siv cov tshuaj tua kab mob.
⑤ Muaj CMC ua tus neeg sawv cev kho mob rau cov av nkos flushing kua, uas tuaj yeem tiv taus cov pa phem ntawm ntau cov ntsev soluble.
⑥ CMC-muaj av nkos muaj kev ruaj ntseg zoo thiab tuaj yeem txo cov dej poob txawm tias qhov kub siab tshaj 150 ° C.
CMC nrog cov viscosity siab thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas tsis muaj qhov ntom ntom, thiab CMC nrog cov viscosity tsawg thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas muaj qhov ntom ntom. Kev xaiv ntawm CMC yuav tsum txiav txim siab raws li cov xwm txheej sib txawv xws li hom av nkos, cheeb tsam, thiab qhov tob tob.
