Dampening tov concentration tswj
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Nyob rau hauv ntau lub tshuab luam ntawv, thaum siv cov tshuaj tsis haum, tsuas yog cov pH ntawm dampening kua yuav tsum tau tswj raws li qhov yuav tsum tau muaj (pH 5.0-5.4), thiab cov concentration ntawm dampening tov yog neglected. Qhov tseeb, thaum lub concentration ntawm cov ciav kua hloov zoo heev, nws pH hloov tsis pom tseeb. Yog li no, nws yog qhov tsis muaj peev xwm tswj hwm tus nqi pH xwb. Vim hais tias qhov kev hloov ntawm concentration yuav hloov nws muaj pes tsawg leeg, yog li cuam tshuam qhov nyiaj tshuav ntawm tus number case thiab dej; qhov hloov ntawm cov ntsiab lus ntawm dampening kua yuav tau ua rau kev hloov ntawm surfactant concentration, uas yuav ua rau qhov hloov ntawm qhov nro qhov nro, thiab thaum kawg cuam tshuam rau cov nyhuv dampening, ua rau qhov zoo ntawm cov khoom luam tawm. poob. Yog li ntawd, qhov concentration of dampening solution yog ib qho tseem ceeb hauv qhov zoo ntawm cov ntawv luam tawm. Peb yuav tsum tswj cov concentration ntawm dampening kua thaum tswj lub pH ruaj khov.
Kev txiav txim siab ntawm kev cob qhia
Txoj kev ntxhib dampening yuav ntsuas tau los ntawm kev ntsuas cov lus coj ua ntawm dampening kua. Lub conductivity ntawm dampening kua mas nws txawv heev hauv ib qho pH ntau. Qhov kev hloov ntawm qhov kev daws teeb meem ntawm dampening thiab nws qhov kev hloov ntawm kev hloov yog txiav txim siab los ntawm kev sim. Ib txoj kev sib raug zoo, uas yog, qhov ntau dua cov concentration, qhov ntau dua cov conductivity, ces ib qho nqi yuav tsum muaj nyob hauv qhov ntau ntawm kev hloov raws li nws cov kev ntxim siab ntxim li tus nqi. Muaj ntau ntau lwm yam uas cuam tshuam rau kev coj ua. Tamsim no tau pom tias tib qho kev xau pov tseg, nws tau npaj los ntawm dej nyob hauv ntau qhov chaw. Txawm hais tias tib lub ntsiab ntawm dampening daws yog dispensed, lawv conductivity yog sib txawv, vim hais tias qhov no yog hais txog dej. Cov teeb meem ntawm kev ua paug muaj feem xyuam rau tus nqi ntawm Ca2 + thiab Mg2 nyob hauv dej. Yog tias tib cov dej sib xyaw nrog ntau hom tshuaj dampening syrup los npaj tib lub ntsiab lus ntawm dampening kua, hluav taws xob conductivity sib txawv, thiab hluav taws xob conductivity loj, qhia tias muaj ntau ions nyob rau hauv cov tshuaj, thiab ib txhia ions muaj kev ntxim ntawm luam ntawv. Yog hais tias cov concentration ntawm Ca2 + los yog Mg2 + hauv dampening tov yog siab dhau, tus number case yuav emulsified, uas yuav hla lub ziab ntawm lub blot. Ntxiv mus, nyob rau hauv txoj kev ceev ntaub ntawv ceev, Mg (HCO3) 2 thiab Ca (HCO3) nyob rau hauv kev daws teeb meem yuav tshwm sim los ntawm kub yam. 2 Decomposition, tsim cov dej tsis tsim kua txob CaCO3, MgCO3, nrog rau tus cag dej, yooj yim los tiv thaiv dej, ib qho kev qias neeg vim tsis ua hauj lwm, nws yog ib qho tsim nyog yuav tau kho cov dej, thiab ces npaj.
Vim tias muaj cov xwm txheej saum toj no, peb yuav tsum xyuas tias tus nqi pH yog nyob nruab nrab ntawm 5.0 thiab 5.4 raws li dej zoo ntawm cov dej siv ua ntej npaj cov tshuaj tsis haum. Tom qab ntawd, qhov kev sib tham ntawm qhov sib txawv ntawm qhov sib txawv yog ntsuas los ntawm txoj kev sim, thiab qhov kev sib tw yog kos. Qhov ntau ntawm cov nqi, thiab tom qab ntawd tsis pub dhau qhov no, nrhiav tau ib co nqi ntawm cov ntawv luam tawm los ntawm qhov zoo ntawm cov teeb meem luam tawm, raws li tus txheej txheem tus nqi siv yav tom ntej no siv dampening solution los npaj dampening kua. Cov dej tsis zoo, ntau hom tshuaj dampening, cov conductivity ntawm qhov zoo tshaj plaws ntawm cov nyhuv nyhuv tsis zoo li qub, tsis muaj cuabkav yuavtsum, ua ntej qhov kev sim, tuaj yeem kuaj xyuas raws li cov qauv saum toj no, yuav ua rau qhov zoo tshaj plaws ntximtxhob, tej zaum yuav xav sim .
