* Cov yam ntxwv ntawm cov khoom:
1. Kev tiv thaiv zoo ntawm cov av, ua rau lub txheej yooj yim los ntxuav tom qab raug kuab paug lossis muaj kuab paug.
2, tsis kam dej zoo: xim pleev xim rau phab ntsa sab nraud uas raug rau huab cua, feem ntau yuav raug ntxuav los ntawm nag.
3, tiv taus huab cua zoo: lub txheej txheej raug rau huab cua, kom tiv taus cua, hnub, ntsev tsuag corrosion, nag, txias thiab cua sov hloov pauv, thiab lwm yam, tsis yooj yim rau tawg, chalking, spalling, discoloration thiab lwm yam.
4, zoo tiv taus pwm: cov txheej txheej phab ntsa sab nraud yooj yim rau cov pwm hauv cov chaw noo noo. Yog li ntawd, cov zaj duab xis txheej yuav tsum tau tiv thaiv kev loj hlob ntawm pwm thiab algae.
5, zoo nkauj kho kom zoo nkauj: xav tau xim pleev xim rau phab ntsa sab nraud thiab khaws xim zoo heev, tuaj yeem tswj tau qhov kev ua kom zoo nkauj qub rau lub sijhawm ntev.
* Daim Ntawv Thov Khoom:
Siv tau raucib, phab ntsa pob zeb thiab lwm yam khoom siv, dav siv rau sab nraud phab ntsa ntawm thaj chaw nyob, cov chaw tsim khoom, tsev kho mob, tsev kawm ntawv thiab lwm qhov chaw.
* Kev Kho Mob Nto:
Qhov saum npoo ntawm cov khoom uas yuav tsum tau pleev xim yuav tsum huv si, huv si thiab qhuav. Cov dej noo ntawm phab ntsa yuav tsum tsawg dua 15% thiab pH yuav tsum tsawg dua 10.
* Cov ntaub ntawv kev siv:

| 1 | Lub xeev nyob rau hauv ib lub thawv | Tsis muaj caking, lub xeev sib xws tom qab do | |
| 2 | Kev ruaj khov ntawm kev cia khoom thermal | Dhau | |
| 3 | Kev ruaj khov kub tsawg | Tsis muaj kev puas tsuaj | |
| 4 | Lub Sijhawm Qhuav Ntawm Qhov Chaw, h | ≤4 | |
| 5 | Tag Nrho Zaj Duab Xis | Zaj duab xis tsos | zaj duab xis xim yog qhov ib txwm muaj thiab tsis muaj kev hloov pauv pom tseeb. |

*Txoj kev tsim kho:
Txhuam, menyuam, tshuaj tsuag.
■Kev kho cov khoom sivTshem tawm cov hmoov av, roj, pwm algae thiab lwm yam khoom lo rau ntawm qhov chaw pleev xim kom qhov chaw huv, qhuav thiab tiaj tus. Cov dej noo ntawm qhov chaw ntawm phab ntsa tsawg dua 10% thiab pH tsawg dua 10. Phab ntsa qub siv rab riam los tshem cov xim qub uas tsis muaj zog thiab tshem tawm cov hmoov av thiab cov khoom qias neeg ntawm qhov chaw, ua kom du, thiab ziab kom huv si.
■Cib puag ncig kev qhia| 5-35 ° C, av noo tsawg dua 85%; kev tsim kho lub caij ntuj sov kom tiv thaiv kev qhuav sai dhau, kev tsim kho lub caij ntuj no txwv tsis pub ci, nag thiab xuab zeb thiab lwm yam huab cua hnyav raug ncua kev tsim kho.
■Lub sijhawm rov pleev xim dua| Zaj duab xis qhuav 30 micron, 25-30 ° C: qhov chaw qhuav rau 30 feeb; qhuav tawv rau 60 feeb; rov txheej dua ntawm 2 teev.
■Kev ntxuav cov cuab yeej| Tom qab nres pleev xim thiab pleev xim tas, thov ntxuav cov khoom siv nrog dej.
■Lub theoretical siv ntawm cov xim| 7-9 m2/kg/ib zaug dhau (zaj duab qhuav tuab li 30 microns), qhov ntau ntawm kev siv xim txawv vim qhov roughness ntawm qhov chaw tsim kho tiag tiag thiab qhov piv ntawm kev dilution.
* Kev thauj mus los cia:
Khaws cia rau qhov kub siab tshaj 5 °C rau qhov chaw txias, qhuav qis dua 35 °C, zam kev tshav ntuj ncaj qha thiab kaw lub thawv kom nruj. Nws yuav tsum khaws cia cais ntawm cov kua qaub muaj zog, alkalis, cov tshuaj oxidants muaj zog, zaub mov thiab tsiaj txhu.
