Cov tshuaj lom neeg muaj pes tsawg leeg thiab ua haujlwm ntawm chav kho

Chav tsev txhim kho yog qhov tseem ceeb ntawm cov duab ua tiav, tshwj xeeb hauv kev yees duab ua pa. Nws cov haujlwm tseem ceeb yog kom yaj cov nyiaj tsis muaj txiaj ntsig los ntawm kev siv tshuaj lom neeg thiab kho cov duab, kom ua tiav cov duab kom ruaj khov thiab meej ntawm cov duab. Cov tshuaj lom neeg muaj kuab lom ntawm lub tsev txhim kho feem ntau muaj cov tshuaj tiv thaiv, tus tsis muaj tus neeg sawv cev, txhua yam uas ua haujlwm synergistically kom ua tiav kev txhim kho.

Tus neeg saib xyuas kev txhim kho yog cov tseem ceeb ntawm lub tsev txhim kho thiab feem ntau sodium thiosulfate (hypo) lossis ammonium thiosulfate. Sodium thiosulfate reacts nrog cov nyiaj tsis muaj nyiaj halide los ua ib qho soluble nyiaj thiosulfate complex, uas tuaj yeem ntxuav tawm ntawm daim ntawv thaij duab lossis zaj duab xis. Ammonium thiosulfate muaj cov nrawm nrawm tab sis tuaj yeem cuam tshuam duab kev ruaj ntseg, ua rau nws siv feem ntau siv hauv kev nrawm.

Cov neeg sawv cev tiv thaiv (xws li sodium sulfite) tiv thaiv oxidation ntawm tus txhim kho thiab ntev lub neej ntawm kev daws teeb meem. Sodium sulfite reacts nrog oxygen rau saum huab cua, tiv thaiv sodium thiosulfate los ntawm kev ua tiav, yog li tswj qhov ruaj khov ntawm kev txhim kho kev daws teeb meem.

Buffers (xws li acetic acid los yog boric acid) yog siv los kho cov ph ntawm kev daws cov kua tshuaj, kom muaj cov kua qaub rau hauv {{} pont pib ib puag ncig. Ib qhov ruaj khov ntev pab txhim kho kev txuag nyiaj txiag thiab txo cov corrosion rau cov ntawv yees duab lossis yeeb yaj kiab.

Tsis tas li ntawd, lub tsev txhim kho yuav muaj surfactants lossis zaj duab xis hardeners (xws li formassium alum) los txhim kho cov khoom siv hluav taws xob lossis txhim kho cov neeg kho tshuab lub zog ntawm cov duab.

Thaum lub sij hawm niaj hnub digital laij thev naus laus zis tau txo nws cov khoom siv tshuaj lom neeg tseem ceeb rau cov duab zoo hauv kev yees duab thiab kev tswj hwm kev khaws cia. Los ntawm kev tswj cov tshuaj zoo, kho cov chav nyob ua tiav tau zoo thiab ruaj khov duab txhim kho, muab cov ntaub ntawv muab tau ruaj khov rau cov duab kos duab thiab kev tshawb fawb.
