Cov tshuaj tua hluav taws hauv dej (hom polymer gel uas tsis ua rau ib puag ncig puas tsuaj)
I. Txheej txheem cej luam ntawm cov khoom
Cov tshuaj tua hluav taws polymer gel yog ib hom hmoov dawb. Cov khoom me me no muaj zog tua hluav taws heev thaum sib xyaw nrog dej. Nws muaj cov tshuaj tsawg, yooj yim siv, thiab ruaj khov heev ntawm qhov kub qis dua 500ºC, tsis ua rau cov khoom siv tua hluav taws xeb. Yog li ntawd, cov gel tuaj yeem npaj ua ntej siv lossis sib tov ua ntej thiab khaws cia rau hauv cov thoob dej rau kev npaj.
Ua ib yam khoom siv tua hluav taws, cov polymer gel no muaj peev xwm nqus dej tau zoo, khaws dej tau ntev, tiv taus hluav taws zoo heev, lo rau zoo, tsis ua rau ib puag ncig puas tsuaj, tsis muaj tshuaj lom, yooj yim siv, thiab yooj yim thauj thiab khaws cia. Nws tsis tsuas yog kaw cov dej ntau xwb tab sis kuj ua rau cov khoom kub hnyiab txias sai. Thaum siv, nws tsim ib txheej hydrogel rau ntawm qhov chaw ntawm cov khoom kom cais cov pa tawm thaum tiv thaiv kev sib kis ntawm cov pa lom thiab cov pa phem. Cov txheej gel no nqus tau cov cua sov ntau ntawm cov khoom kub hnyiab, yog li ntawd txo lawv qhov kub ntawm qhov chaw kom tswj tau kev sib kis hluav taws thiab ua tiav kev tua hluav taws sai thiab zoo.
Cov tshuaj tua hluav taws uas muaj cov tshuaj gel no zoo heev, tsis ua rau ib puag ncig puas tsuaj, thiab txuag dej. Lub tsheb tua hluav taws uas muaj cov tshuaj gel no zoo ib yam li 20 lub tsheb tua hluav taws uas siv dej tua xwb. Cov ntsiab cai thiab cov txheej txheem yeej zoo ib yam li cov tshuaj tua hluav taws uas siv dej tua. Txawm li cas los xij, thaum tua cov hluav taws Class A, nws cov txiaj ntsig tiv taus hluav taws ntau dua 6 npaug ntawm dej; rau cov hluav taws hauv hav zoov thiab cov nyom, cov txiaj ntsig tiv taus hluav taws ntau dua 10 npaug ntawm dej.
II. Scope ntawm Daim Ntawv Thov
Cov tshuaj tua hluav taws polymer gel uas muaj 0.2% ~ 0.4% concentration tuaj yeem tsim cov tshuaj tua hluav taws gel hauv 3 feeb. Thaum txau rau ntawm cov khoom khov kho, nws tam sim ntawd tsim cov zaj duab xis gel tuab rau ntawm qhov chaw, uas cais cov huab cua, txias qhov chaw ntawm cov khoom, thiab nqus tau ntau cov cua sov uas ua rau muaj kev tiv thaiv hluav taws zoo heev thiab tua hluav taws. Nws muaj txiaj ntsig zoo rau kev tua hluav taws hauv hav zoov, nyom, thiab hauv nroog Class A (cov khoom khov kho). Cov pa roj carbon dioxide thiab cov pa dej uas tsim los ntawm kev hlawv ntawm cov resin superabsorbent tsis yog cov hluav taws kub thiab tsis muaj tshuaj lom.
III. Cov yam ntxwv ntawm cov khoom
- Txuag DejCov tshuaj tua hluav taws polymer gel muaj qhov nqus dej ntawm 400-750 npaug, ua rau kev siv dej zoo dua qub. Yuav tsum siv dej tsawg dua ntawm qhov chaw tua hluav taws kom tswj tau qhov hluav taws kub thiab tua hluav taws sai sai.
- Kev Ua Haujlwm ZooThaum tua hluav taws Class A, hav zoov, thiab nyom, cov tshuaj tua hluav taws hydrogel muaj peev xwm lo rau ntau dua 5 npaug ntawm dej, thiab tiv taus hluav taws ntau dua 6 npaug ntawm dej. Rau cov hluav taws hav zoov thiab nyom, cov tshuaj tiv taus hluav taws ntau dua 10 npaug ntawm dej. Kev lo rau yuav txawv me ntsis nyob ntawm cov khoom siv ntawm cov khoom siv hluav taws kub.
- Kev phooj ywg ib puag ncigTom qab tua hluav taws tas, cov tshuaj tua hluav taws hydrogel uas seem nyob hauv qhov chaw tsis ua rau muaj kuab paug rau ib puag ncig thiab pab khaws cov av noo. Nws tuaj yeem lwj mus ua dej thiab cov pa roj carbon dioxide hauv ib lub sijhawm yam tsis ua rau muaj kuab paug rau cov dej lossis ib puag ncig.
