Tej teeb meem nyob rau hauv tus cwj pwm thiab dej tshuav nyiaj li cas: tswj kev saib xyuas me nyuam me me
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.

Hauv kev xa ntawv luam tawm, phaj dej yog thawj zaug ntub dej los ntawm lub phaj ntawv, thiab qhov dawb paug ntawm daim phaj luam yog hydrophilic thiab adsorbs ib qhov dej ntawm cov dej. Daim duab nrig yog lipophilic thiab tsis nqus dej noo; lub phaj ntawv sau yog kos los ntawm cov phaj cov phom. Nyob rau lub sij hawm no, daim duab nraaj yuav nqus ib qho ntawm cov lej. Los ntawm embossing, noo noo thiab kua mem sau yog xa rau daim ntawv los ntawm phaj lub tog raj kheej thiab pam lub tog raj kheej. Qhov teeb meem ntawm qhov txheej txheem no yog qhov nyiaj tshuav ntawm cov cwj mem thiab dej, thiab qhov kev daws teeb meem yog qhov tseem ceeb.
Qhov muaj pes tsawg leeg thiab kev ua haujlwm ntawm dampening kua
Qhov kev xaiv ntawm dampening daws yuav tsum tau ceev faj heev, los xyuas seb nws muaj cov khoom xyaw nram qab no: tsis tuaj, phaj tiv thaiv, ntxig tus neeg sawv cev, txhuam, ua noj. Biocides thiab anti-foaming cov neeg ua hauj lawm, lwm yam zoo li Lub tsis yeem pabcuam kom tswj cov nqi pH ntawm dampening kua. Vim hais tias txoj kev dampening feem ntau yog acidic, nrog slowness; lub pH ntawm dampening daws yuav fluctuate heev, thiab tus nqi ntxiv yog tsis haum. Yuav cuam tshuam rau lub neej ntawm lub phaj (corrosion on the plate). Tsis tas li ntawd, nws tsis yooj yim rau koj qhuav ntshav, tshwj xeeb yog tus cwj pwm uas muaj xim ntxig rau xim hlau.
Thaum lub sij hawm luam ntawv, qhov kev txhim kho ntawm qhov chaw mos yog ib txwm nyob hauv kev sib txuas nrog cov ntawv xov xwm, thiab cov duab tsis muaj duab (cov quav hauv cov quav ntsev) ntawm cov ntawv xov xwm luam tawm tsis tu ncua, yog li ntawd cov kua roj ntawm cov ntawv phom luam yog txo, qias neeg ploj phaj phenomenon. Cov phaj tiv thaiv tsis tu ncua ntxiv rau hauv cov txheej txheem dej hauv cov txheej txheem kom tsis txhob muaj kev sib luag thiab ua kom cov dej ruaj khov ntawm lub phaj. Cov phom tiv thaiv kuj muaj ib daim ntawv tiv thaiv cov kua nplaum, thiab tsis tas siv lub phuam thaum muaj ib ntus kaw.
Hauv cov txheej txheem luam ntawv, siv cov tshuaj tsis haum me ntsis yog nws tseem tsis tau lo av, yog li tus neeg saib xyuas hauv tsev yog qhov tseem ceeb heev. Tus neeg saib xyuas lub xov tooj tuaj yeem txo qhov kev nruj ntawm dampening tov, yog li ntawd cov dej noo yog sib npaug ntawm cov ntawv luam tawm, thiab siv cov tshuaj phem zoo tuaj yeem ua tiav nrog tsawg dampening kua. Feem ntau, cov cawv ntxiv nyob rau hauv cov tshuaj tsis haum yog ntau dua 15%, thiab cov kua dej tshiab niaj hnub no muaj ib tus neeg ntxhib ntxi, uas tuaj yeem txo qhov qaug cawv.
Cov tshuaj tiv thaiv tiv thaiv cov hlau ua vim tias cov kua dej ua tsis txaus ntseeg thiab qaug zog rau cov hlau ntawm cov xovxwm; cov neeg tsim kev txhawb nqa kom qhuav ntawm tus cwj mem; Biocides tiv thaiv kev loj hlob ntawm algae thiab microorganisms nyob rau hauv dej system. Tsis txhob khoob ntawm txoj hlab pas; tus neeg ua hauj lwm tiv thaiv tus neeg ua noj ua haus tiv thaiv ua npuas ua rau vim qhov loj npaum li cov npuas dej hauv lub tank tsis yog ib qho zoo rau kev ntub cov phaj.
Niaj hnub tshiab dampening daws yuav tsum muaj cov khoom xyaw saum toj no. Tsis tas li ntawd, tus neeg siv yuav tsum kuaj qhov nyuaj, kev ua tus nqi thiab tus nqi pH ntawm cov dej siv hauv tsev tsim ua ke nrog dej tsis zoo thiab lwm yam kev mob ntawm cov tshuab luam ntawv. Lub chaw tsim tshuaj txhuam hniav yuav tsum tau muab cov tshuaj tsis haum thiab lwm yam tsis tau raws li tus neeg siv cov dej tsis zoo. Cov kev txwv no tsis yog muaj xws li nyiaj dampening kua tshuaj kho, qhov nyiaj isopropanol (cawv) ntxiv, pH ntawm dampening kua thiab coj, thiab lwm yam.
Siv cov ciav dej
Qhov nyiaj dampening tshuaj feem ntau tswj ntawm 2% mus rau 3%, tab sis yog hais tias qhov ntsuas cov cuab yeej tsim nyog uas ploj lawm, los sis yog tias qhov kev rho tawm tsis siv lub tshuab tsis zoo, tus neeg teb xov tooj tsuas ntxiv tau los ntawm kev ua, uas ua rau kev khiav. Muaj ntau cov teeb meem hauv kev tswj ntawm cov kua.
Yog tias cov tshuaj dampening tsawg dhau lawm, cov ntawv phaj ntawv yooj yim heev, thiab lub sijhawm hloov mus ntev yog ntev; nws yog qhov nyuaj ua kom cuag tau tus lej tsis tshuav nyiaj li cas, nws tsis yooj yim kom tau txais cov txiaj ntsig zoo ntawm tus lej xim, thiab txoj kev pheej hmoo ntawm kev siv hluav taws xob cav ntau zog. Yog hais tias tus nqi ntawm cov kua phaus dej loj dhau lawm, tus number case yog yooj yim tshaj-emulsified, thiab tus cwj pwm xaj xim tsis yooj yim uas tswj; tus number case yog smeared, tus number case yog tawg, dej thoob thiab dej ntawm cov quav dej paug; tus cwj mem xaws number case yog tsis muab inked, thiab tus number case yog yooj yim nyob rau daim pam.
Yuav kom daws tau cov teeb meem no, ib qho kev ntsuas tus ntsuas yuav tsum tau ntxiv rau kev siv tes xoo kom haum ntxiv rau qhov sib ntxiv ntawm qhov sib ntxiv; yog tias muaj kev siv twj ntxiv tuaj, nws yuav tsum tau soj ntsuam xyuas thiab tswj xyuas kom nws lub cev khiav lag luam.
Thaum siv cov tshuaj tshiab dampening tshiab, cov cawv yuav tsum tswj li ntawm 10%. Feem ntau, tus neeg teb xov tooj xav tias qhov loj npaum li cov cawv ntxiv, tsawg dua cov phaj qias lawm, yog li tus nqi cawv yeej ib txwm loj heev. Qhov tseeb, thaum haus dej cawv ntau dhau lawm, daim tawv nqaij yuav tsum muaj zog, thiab daim ntawv luam tawm yuav ua rau hmoov ntawv hmoov; tus number case yuav yooj yim emulsified thiab cuam tshuam qhov zoo ntawm cov ntawv luam tawm.
Cov pH thiab kev coj ua yog feem ntau yog siv los ua kom pom thiab saib xyuas qhov teeb meem ntawm cov ciav dej. Qhov kev kuaj pom tseeb tias thaum tus nqi pH yog nyob rau ntau qhov ntawm 4.8 rau 5.3, luam ntawv yog qhov chaw ruaj khov, phaj ntawv muaj lub neej ntev tshaj plaws, kev luam zoo yog qhov zoo tshaj plaws, tus number case tshuav yog qhov yooj yim tshaj plaws los tswj, thiab tus nqi pH yog txiav txim tsis yog los ntawm qhov nyiaj ntawm cov ciav dej, tab sis kuj yog los ntawm daim ntawv. Cov nyhuv ntawm acidity thiab alkalinity. Kev coj cwj pwm feem ntau yuav raug tswj ntawm (1400 ± 200) μs, tus nqi hluav taws xob muaj peev xwm ua rau dej tsis txaus, haus dej cawv, hmoov av thiab kua number case, yog li tus nqi kwv yees li 800 ~ 2000μs, tab sis thaum lub ciav dej zoo li pom tseeb Thaum tau raug kab mob, nws yuav tsum rov qab kho dua.
Nyob rau hauv luv luv, tswj lub dampening daws thaum lub sij hawm luam ntawv feem ntau muaj ib tug multiplier siv.
