(3) Concentration tswj kev dampening kua
Qhov concentration ntawm cov ciav hlau hais txog qhov nyiaj ntawm cov khoom tsim muaj nyob rau hauv cov ciav dej. Tshaj lag luam yog feem ntau yog ib qho hmoov hmoov los yog dampening kua.
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 li ntawm qhov yuav tsum tau muaj (pH 5.0-6.0), thiab cov concentration ntawm dampening tov yog neglected. Txij li ib feem ntawm txoj kev dampening muaj ntau dua, thaum lub concentration ntawm dampening kua hloov zoo heev, nws cov pH (xws li, tus nqi pH) tsis hloov yig. Yog li no, nws yog qhov tsis muaj peev xwm tswj hwm tus nqi pH xwb. .
Vim hais tias cov concentration ntawm dampening kua hloov nws cov tshuaj lom neeg muaj pes tsawg leeg, uas cuam tshuam tus number case thiab dej tshuav nyiaj li cas. Cov kev hloov hauv cov ntsiab lus ntawm cov ciav dej txhuam kuj ua rau muaj kev hloov hauv cov ntsiab lus ntawm cov ciaj sia, ua rau muaj kev hloov hauv qhov nro. Yog hais tias cov concentration hauv qhov ciav kua ntau dhau, tus number case yuav emulsified thiab cov ntshav yuav hindered. Hauv kev ua haujlwm siab ceev, Mg (HCO3) 2 thiab Ca (HCO3) 2 nyob rau hauv txoj kev dampening yuav tsum tau yog vim kub kub, ua rau muaj insolubilization. CaCO3 calcium carbonate thiab MgCO3 magnesium carbonate nyob rau hauv dej koom rau cov dej rau cov menyuam, uas yooj yim tiv thaiv dej hloov thiab khov khov tsis ua haujlwm. Yog li ntawd, nws yog ib qhov tsim nyog yuav tau muag cov dej ua ntej kev npaj. 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 kev ruaj khov pH (pH).
Yuav kom luam cov duab zoo nkauj thiab paub meej, qhov tsis muaj teebmeem me me, thiab qhov kev sib txuas ntawm cov kua txhuam tsev yuav tsum yog kho raws li cov kev luam ntawv kom paub meej tias cov ntawv sau zoo tshaj plaws yog luam tawm.
1, ntawv cov khoom thiab cov ciav dej ntsiab concentration
Thaum cov ntawv luam ntawv xoob los yog muaj hmoov av hauv daim ntawv, cov luam ntawv feem ntau muaj ntawv thiab ntawv hmoov rau ntawm daim pam vim tias qhov siab tshaj plaws ntawm tus lej luam ntawv, uas yuav txhim kho txoj kev txhuam ntawm cov ntawv phaj thiab ua cov ntawv luam ntawv yooj yim kom tau qias neeg. Hauv qhov no, qhov concentration ntawm cov ciav dej yuav tsum tau nce ntau yam tsim nyog. Thaum twg cov ntawv luam tawm nrog lub siab thiab ceev nrooj, tshwj xeeb tshaj yog thaum luam ntawv coated thiab iav ntawv, cov tshuaj tsis haum yuav tsum raug txo kom tsawg. concentration.
2, number case khoom thiab cov ciav dej ntsiab concentration
Vim muaj cov khoom sib txawv ntawm cov ntawv luam tawm, cov khoom ntawm cov kua hluav taws xob, lub cev thiab acid acid kuj sib txawv, thiab cov lus teb rau cov concentration of dampening solution yuav txawv. Yog li ntawd, qhov kev ywj pheej ntawm dampening daws yuav tsum tau kho raws li tsim nyog. Feem ntau, qhov kev to taub ntawm cov ciav dej yog raws li lub hauv paus ntsiab lus tias cov ntsiab lus ntawm cov ntawv liab liab yog ntau dua cov ntsiab lus ntawm cov cwj mem dub; cov concentration thaum luam tawm cov cwj mem dub yog ntau dua qhov concentration ntawm cyan cached luam; thiab cov concentration thaum luam tawm cov xaj tsaus nti muaj ntau dua Lub voos xwm txheej ntawm cov ntawv luam lub teeb duab.
3, qhov nyiaj desiccant thiab cov concentration ntawm dampening kua
Thaum luam tawm cov xim phaj cov khoom muag, kom ua kom zom zaws ntawm cov cwj mem qhuav, nws yog qhov yuav tsum tau ntxiv cov roj ziab rau tus cwj pwm, uas tseem ua rau cov zauv ntawm cov number case thicker thiab cov viscosity tsub kom, seem ntawm daim ntawv luam tawm yog nce, kom qhov muab tshuaj yog yooj yim generated. Lub version ntawm cov neeg mob. Raws li qhov teeb meem no, cov khoom tsim kho yuav tsum tau nce raws li qhov tsim nyog.
4, luam ntawv phaj thiab cov ciav hlau kua concentration
Cov khoom luam tawm muaj nyob hauv ntau qhov kev teeb tsa, los ntawm cov khoom sib ntxais thiab cov ntaub ntawv thiab textured. Yog hais tias qhov tsim teeb meem yog cov kab hauv kab thiab cov ntawv raws li, qhov concentration ntawm cov ciav dej yuav tsum raug kho kom haum raws li qhov chaw loj dua ntim khoom. Yog tias tag nrho cov qauv screen, qhov concentration of dampening solution yuav tsum muab kho kom haum.
5, kev kub taub hau thiab dampening tov concentration
Thaum ntsuas kub ntawm lub chaw luam ntawv nce lawm, txoj kev xav ntawm cov khoom yuav ua rau lub cev qeeb, qhov fluidity ntawm tus number case yuav nce, thiab tib lub sij hawm, dawb dawb fatty acids yuav decomposed, uas yuav ua rau daim ntawv luam yooj yim tsim cov av . Yog li ntawd, thaum lub ntsuas kub siab loj, cov tshuaj tsis haum yuav tsum tau nce ntxiv. concentration.
6, luam ntawv ceev thiab cov ciav dej ntsiab concentration
Vim tias tus cwj mem muaj thixotropic tus cwj pwm, thaum lub sij hawm luam ntawv siab siab, tus cwj mem number ntawm lub tshuab luam ntawv muaj kev sib txhuam coefficient loj, thiab nws yog qhov yooj yim los ua kom muaj cua sov ua kom muaj tus cwj pwm nyias, kom lub hwjchim xim muaj zog, thiab case number case yog lub teeb, thiab tus lej number case yuav tsum tau nce raws li kom tob. Daim ntawv luam tawm kua mis, yog li ntawd lub phaj yog nws lo av. Yog li, thaum lub sij hawm luam ntawv siab siab, qhov kev pom zoo ntawm cov ciav dej yuav tsum muaj qhov tsim nyog ntxiv.
7, yog tias cov ntawv luam siab siab siab thiab qhov thwjtim ntawm daim pam thiab daim kab xev yog ib qho nyuaj, nws yuav tsum raug xam tias yuav ua rau kom muaj qhov sib xyaws ntawm cov ciav dej. Thiaj li yuav ua kom tau zoo dua cov nyhuv nyuab nyuab heev. Qhov saum toj no qhia tau hais tias qhov concentration of dampening solution yuav tsum tau ua tib zoo xam raws li ntau yam kev mob.
Txiav txim siab ntawm qhov concentration ntawm dampening daws:
Qhov concentration ntawm qhov kev txhim kho ntawm cov ciav hlau yuav txiav txim siab los ntawm kev ntsuas cov khoom siv. Nws muaj pov thawj los ntawm cov kev sim uas muaj kev sib raug zoo ntawm qhov kev hloov ntawm qhov kev txhim kho ntawm cov ciav dej thiab nws cov kev hloov ntawm lub cev, uas yog, qhov ntau dua qhov concentration, ntau dua qhov kev sib txuas, ces nws yuav tsum tau hloov. Nrhiav ib qho muaj nqis rau qhov ntau li nws txoj kev ntxim siab ntxig tus nqi. Peb yuav tsum siv cov dej mos thaum tsim cov tshuaj dampening kom paub meej tias nws cov nqi pH yog nruab nrab ntawm 4.5 thiab 5.5, thiab kev sib txuas lus yuav tsum yog ntawm 1200 thiab 600 peb / cm.
