Thaum cov chaw ntxhua khaub ncaws ntxuav cov ntaub pua chaw pw hauv tsev so, cov ntaub pua chaw pw uas siv tau ntev lawm feem ntau yuav tawg yooj yim thaum raug dua. Vim li cas?
Cov ntaub pua chaw pw hauv tsev so muaj lub neej ua haujlwm ntev. Yog li ntawd, lub tsev so yuav tsum tsis txhob tsuas yog ntxuav thiab tswj cov paj rwb ib txwm muaj xwb tab sis kuj tseem yuav tsum tiv thaiv cov ntaub pua chaw pw kom ntev nws lub neej ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauvcov chaw ntxhua khaub ncawsNrog rau kev lag luam xauj ntaub pua chaw pw, ib hlis ntxiv ntawm lub neej ua haujlwm ntaub pua chaw pw tuaj yeem txuag tau nyiaj rau cov chaw ntxhua khaub ncaws. Los ntawm kev tswj cov pH ntawm cov ntaub pua chaw pw, lub neej ua haujlwm ntaub pua chaw pw tuaj yeem ntev dua.
Teeb Meem Ua Los Ntawm pH Siab Ntev
Lub pH siab ntev yuav ua rau puas tsuaj rau cov ntaub linen.
Paj rwb ntshiab: cov qhov me me, cov npoo tawg thiab cov ces kaum, nyias dua thiab yooj yim tawg, xim tsaus nti, qhov mos txo qis
Paj rwb sib xyaws ua ke: cov xim tsaus nti, qhov paj rwb poob tawm, poob qhov elasticity, muaj tawg thiab frayed ces kaum, thiab cov npoo folded poob tawm.
Kev cuam tshuam rau cov ntaub linen
❑ Cov tshuaj ntxuav alkaline uas seem tshuav rau ntawm cov ntaub pua chaw pw
Txawm hais tias cov tshuaj ntxuav alkaline muaj kev nyab xeeb rau cov paj rwb ntshiab lossis cov ntaub linen sib xyaw thiab tsis ua rau cov ntaub linen puas. Txawm li cas los xij, cov alkaline residue hauv cov fibers yuav ua rau cov ntaub linen grey thiab tawv tom qab ziab thiab ironing ntev.
❑ Dawb ntawm cov ntaub linen
Cov hlau xim xws li hlau feem ntau muaj nyob rau hauv daim ntawv ntawm cov ions lossis cov tshuaj ionic. Yog tias cov dej uas muaj cov ions hlau raug cua sov thiab ntxuav nrog cov tshuaj ntxuav alkaline lossis ntxuav nrog cov tshuaj oxidants, vim yog tus nqi PH siab, cov tshuaj alkaline ua rau cov ions hlau sib xyaw, nws yuav tawm cov xim av liab rau ntawm cov ntaub linen, uas nyuaj heev rau tshem tawm thiab cuam tshuam rau qhov dawb ntawm cov ntaub linen.
❑ Qhov mos ntawm cov ntaub linen
Feem ntau cov tshuaj ua kom mos mos siv rau hauv kev siv cov cationic surfactant, uas ua rau cov khoom siv yooj yim tsis ua haujlwm zoo. Yog tias pH ntawm cov ntaub linen siab dhau, nws yuav ua rau daim tawv nqaij ntawm tus neeg siv puas tsuaj thiab cuam tshuam rau qhov zoo ntawm kev ntxuav, kev nplij siab ntawm kev siv, thiablub neej ua haujlwm ntawm linenYog li ntawd, yuav tsum tau saib xyuas kom zoo rau kev tswj pH ntawm cov ntaub linen.
Qhov Tseem Ceeb ntawm Kev Tswj Xyuas pH
Kev tswj cov pH ntawm cov ntaub pua chaw pw yog ua tiav los ntawm kev ntxiv cov kua qaub neutralizing rau theem kawg ntawm cov txheej txheem ntxhua khaub ncaws ib txwm muaj. Kev ntxiv cov kua qaub neutralizing kom raug tuaj yeem kho qhov pH kom nws nyob nruab nrab ntawm 5.5 thiab 6.5, yog li nws tuaj yeem tiv thaiv cov hlau ions hauv dej (calcium thiab magnesium) kom tsis txhob cuam tshuam nrog alkali los tsim cov tshuaj tsis yaj uas tso rau ntawm cov ntaub pua chaw pw. Tsis tas li ntawd, nws yaj qee cov hlau ions hauv dej. Qhov no tiv thaiv cov ntaub pua chaw pw tig xim av thiab tsaus, muaj qhov tsis zoo ntawm tes, tsis ci ntsa iab, thiab cov fiber caking los ntawm alkali residue. Nws yog ib qho pab tau los muab ib puag ncig zoo rau cov tshuaj softener siv, yog li ua kom cov phuam mos dua.
