pH yog qhov tseem ceeb tshaj plaws hauv pas dej da dej chemistry - Nws cuam tshuam rau txhua qhov sib npaug ntawm cov tshuaj hauv cov dej hauv pas dej. pH yog ntsuas ntsuas lub pas dej acidity lossis alkalinity qib. Txawm hais tias qib pH yog qhov tseem ceeb tshaj plaws uas ua rau muaj dej sib npaug, muaj lwm yam tseem ceeb uas cuam tshuam rau cov dej sib npaug.
Qib pH qhia qhov txheeb ze acidity lossis alkalinity ntawm koj cov dej hauv pas dej. pH ntsuas ntawm qhov ntsuas ntawm 0 (muaj zog acid) mus rau 14 (muaj zog alkaline) thiab pH nruab nrab yog 7. Hauv cov pas dej me ntsis alkaline ntawm 7.2 & 7.6 yog qhov zoo tagnrho vim tias qhov ntau yam no yog qhov zoo tshaj plaws rau tib neeg. qhov muag, muab qhov zoo tshaj plaws siv cov tshuaj chlorine dawb thiab muab cov dej uas tsis muaj corrosive lossis scale forming.
Yuav ua li cas ntsuas pH ntawm lub pas dej da dej?
Cov kws tshaj lij hauv pas dej siv cov tshuaj tshwj xeeb, xws li cov kua qaub qhuav lossis hydrochloric acid, kom txo qis pH. Koj tuaj yeem siv cov khoom hu ua TCCA los pab tswj cov qib pH. Tag nrho cov tshuaj no pab tswj cov pH ntawm koj lub pas dej.
Cov khoom siv ntsuas ntsuas 4 qib tshuaj tseem ceeb hauv koj lub pas dej: pH, chlorine, tag nrho alkalinity, thiab calcium hardness. Nws yog ib qho tsim nyog yuav tau yuav cov khoom siv ntsuas kev ntseeg siab rau koj lub pas dej kom paub tseeb tias cov qib nce mus txog kev tswj hwm. Txoj kev no, koj tuaj yeem txheeb xyuas cov tshuaj twg yuav tsum tau ntxiv kom koj lub pas dej da dej pristine nrog qhov tseeb pH.
