Thaum kuv nyuam qhuav pib ua haujlwm nrog kev mob siab LKM, Kuv tsis tuaj yeem xav tias txhua yam tseem ceeb rau lawv ua cov kuab tshuaj. Txawm li cas los xij, ntsib cov kuab tshuaj rau cov xim pleev xim thaum nqa tawm cov haujlwm tom ntej nrog lawv tus kheej tes, Kuv pom tau tias nws tsim nyog saib ntawm cov khoom no. Qhov tseeb yog tias qhov tseeb xaiv ntawm cov kuab tshuaj yog lub luag haujlwm loj, vim tias nyob rau hauv ib rooj plaub zoo, qhov kev kho kom zoo nkauj dua thiab zoo. Tab sis nrog kev xaiv tsis ncaj ncees ntawm cov kuab tshuaj, nws tsis tuaj yeem tawg, tab sis txawm tias cov tsos ntawm npuas, thiab thaum kawg, txhua txoj haujlwm yuav tau rov ua dua tshiab.
Hnyav rau cov xim
Kev teem caij teem tseg ntawm cov khoom thiab cov kev xav tau rau nws
Nyob rau hauv nws tus kheej, cov khoom no uas thaum sib xyaw nrog cov xim pib cov tshuaj tiv thaiv, thiab tom qab ntawd evaporation. Rau coob leej, nws yog qhov tsim nyog xaiv cov peev nyiaj sai, vim tias nws nyob ntawm lub sijhawm ziab cov xim ntawm cov npoo.
Peb siv cov kuab tshuaj pleev xim
Ntxiv rau cov haujlwm tseem ceeb, cov kuab tshuaj rau cov xim tha xim ua si lub luag haujlwm ntawm kev ntxuav ntawm cov cuab yeej thiab cov ntu ntawm LKM. Ntawm no, piv txwv li, yog tias siv cov hmoov xim av, cov kuab tshuaj tsuas ua cov ntaub ntawv ua haujlwm no, vim tias nyob rau hauv cov ntaub ntawv ntawm cov ntaub ntawv thov nws tus kheej, sib xyaw ua ke. Hmoov xim yog thov rau saum npoo hauv daim ntawv qhuav, thiab tom qab ntawd nws yog rhuab. Cia saib ntawm qhov tseem ceeb tshaj plaws uas yuav tsum tau txuas ntxiv rau cov kuab tshuaj:
- Txhawm rau dilute cov xim thiab cov kuab tshuaj tsis tas yuav thov cov rog. Cheebtsam yuav tsum yooj yim ua ib pawg.
- Zaj ntaub nyiaj ua yeeb yaj kiab yuav tsum tshwm sim nyob rau lub sijhawm luv luv
- Cov kuab tshuaj yuav tsum tsis txhob teb rau xim. Yog tias cov tshuaj tiv thaiv pib ntawm cov Cheebtsam, nws yog qhov ua tau los Coagulate Lkm. Tom qab cov txheej txheem xws li, cov khoom yuav raug lwj
- Cov lus sib xyaw yuav tsum tsis txhob hloov nws cov khoom thaum thaum sib cuag nrog dej lossis huab cua
Tshooj ntawm cov ncauj lus: Yuav ua li cas xaiv cov dej ntws ntws?
Cov kuab tshuaj rau cov xim muaj peev xwm faib ua 2 pab pawg uas peb tam sim no thiab xav txog:
- Inorganic - dej los yog kua ammonia. Yog li nws yuav yog chloride lossis phosphate acid ntsev
- Organic - Tsaug rau ntau ntau yam, lawv tau dhau los ua ntau yam rau inorganic cov kuab tshuaj. Cov no tuaj yeem yog roj av lossis dawb tus ntsuj plig - xws li cov kev daws teeb meem sai thiab siv kom tsim cov txha hniav laus lossis acrylate. Kerosene tuaj yeem raug ntaus nqi mus rau chav kawm ntawm nruab nrab cov kuab tshuaj - nws yog qhov haum rau cov roj LCMS thiab acrylic sib xyaw. Tab sis turpentine nws maj mam ploj mus thiab yog haum rau cov varnishes.
Peb cais raws li lub hauv paus
Peb dilute cov xim ntawm kev zais
Txhua cov kuab tshuaj muaj lub hauv paus hauv lawv tus kheej thiab hauv peb cov ntaub ntawv, nws yuav yog:
- Qhov ntsuas qhov tseem ceeb
- Dej cawv
- Hydrocarbon
Qhov tseem ceeb sib xyaw yog txhua tus zoo acetone, uas tej zaum yog qhov xav tau tshaj plaws ntawm txhua yam uas peb paub. Txawm hais tias qhov tseeb tias nws yog ya thiab hluav taws tau lawv tus kheej degreehe thiab chim rau ntau qhov chaw. Acetate yog siv los ua kom qeeb tus neeg sawv cev ziab. Feem ntau cov feem ntau nyiam cov neeg tuaj tshiab ntawm cov duab kos. Nws tsis muaj qhov tsis hnov tsw tsw.
Hnyav rau cov xim
Cov xim tsev sab nrauv yog siv rau cov haujlwm ua ke. Piv txwv li, tsis yog tsuas yog cov khoom, tab sis kuj tseem ua kom cov txheej txheem polymerization. Tsis tas li cov kuab tshuaj no yog sib nrauj qee hom xim. Chav kawm ntawm kev haus cawv sib xyaw suav nrog ethanol, ethylene glycol thiab ethyl cawv. Ethanol yog siv rau acrylic sib tov nyob rau hauv cov txheej txheem ntawm tiav thaj chaw. Tsis txhob hnov qab tias cov tshuaj tua hluav taws yog qhov txaus ntshai rau tib neeg kev noj qab haus huv. Tab sis qhov txawv ntawm methyl cawv los ntawm ethanol tsuas yog nyob rau hauv ntau dua ntawm cov khoom lom. Ethylene glycol muaj cov cuab yeej ntawm ntev evaporation thiab ua tsaug rau qhov no, tag nrho cov txheej txheem polymerization ntawm Nitrolac kuj qeeb.
Hla thiab roj av xa mus rau chav kawm ntawm cov kuab tshuaj hydrocarbon. Lub roj av uas tsis tau siv yog yuav luag tsis siv, tab sis turpentine txig tau tawg roj lkm thiab putty. Ciaj sia nyob rau hauv lub ntiaj teb cov kuab tshuaj yuav tsum tau hu ua dawb dab. Nws tus nqi qis thiab tsawg toxicity thiab yog lub ntsiab ua rau nws muaj koob meej.

Kev nyab xeeb ua haujlwm - tus yuam sij rau kev ua tiav
Peb xaiv cov kuab tshuaj pleev ximThaum lub sijhawm ua haujlwm nrog cov kev daws teeb meem, nws yog ib qho tsim nyog los tiv thaiv nws tus kheej nrog kev pab ntawm cov neeg ua haujlwm. Dilute cov khoom siv, koj xav tau kev tiv thaiv ob txhais tes thiab ua pa plab zom mov. Tsis txhob cia Caustic vapors kom tau mus ua pa plab - nws yuav hem kom hnyav hnyav thiab tsis zoo. Yog hais tias txoj kev daws nkag rau qhov chaw qhib thaj chaw ntawm daim tawv nqaij, cov kev kub hnyiab yog kev tsis taus. Tiv thaiv cov npoo ntawm ob txhais tes tau cov hnab looj tes roj hmab, yog li koj yuav tsum tsis txhob saib xyuas lawv.
Cov kuab tshuaj uas tau siv los tshem tawm cov xim tsev yog thoob ntiaj teb. Ua tsaug rau lawv, pleev xim yog muab tshem tawm hauv txhua qhov chaw. Txawm li cas los xij, txawm li cas los xij, ib txwm them sai sai rau lub hauv paus uas tau raug ntxuav, vim tias cov kuab tshuaj tuaj yeem poob thiab cov qauv no. Ua ntej yuav cov kuab tshuaj uas koj xav tau, nyeem cov lus qhia los ntawm chaw tsim tshuaj paus thiab paub txog cov ntaub ntawv koj xav tau ntawm tus muag khoom.
Tsis yog ib txwm discolving mixtures tuaj yeem raug tshem tawm ntawm lub hauv paus ntawm LKM, qee zaum nws yog qhov tsim nyog los tos lub sijhawm ua ntej qhov pib ntawm cov nyhuv uas yuav tsum muaj. Thiab qee zaum koj yuav tsum siv cov cuab yeej ntxiv. Hauv cov txheej txheem no, nws yog ib qho tseem ceeb kom ua txhua yam ua tib zoo ua tib zoo, nyob rau kom tsis txhob puas.
Cov lus qhia rau kev ua haujlwm
Peb xaiv cov kuab tshuaj pleev xim
Yuav tsum ua raws li cov lus qhia no, kom tag nrho cov txheej txheem ua haujlwm tau tshwm sim raws qib kom yog, thiab kev sib tsoo ntawm cov xim tsis tau tshwm sim. Yog li:
- Siv cov kuab tshuaj uas haum rau cov xim siv. Nws yog qhov tseeb ntawm kev siv cov ntaub ntawv tsis zoo ntawm lawv tus kheej thiab hloov tawm LKM
- Txog kev ntws qhov raug, saib cov lus qhia ntawm kev siv cov chaw tsim tshuaj paus. Nco ntsoov, rau txhua qhov sib xyaw muaj nws tus kheej tus nqi siv nyiaj
- Yog tias koj siv cov khoom uas lawv tsis paub ua ntej. Qhov ntawd tsis tsim nyog los ua lawv ib zaug tag nrho lub hauv paus. Txheeb xyuas cov kuab tshuaj ua ntej ntawm ib ntu me me ntawm cov npoo av, thiab tom qab twb tau siv rau tag nrho cov xaib
- Tau txais tsuas yog cov khoom siv zoo, vim tias nws yog qhov tseem ceeb rau kev ua haujlwm zoo. Tsis txhob xaiv cov khoom siv pheej yig tshaj - tus nqi ntawm cov khoom tsis yog qhov zoo kawg nkaus kom txuag tau ntawm kev ua haujlwm zoo

Qho kawg
Distributor rau cov xim pleev xim rau hauv kev ua tiav xov
Raws li peb to taub, cov kuab tshuaj yog siv tsis tsuas yog tshem cov xim pleev xim, tab sis kuj tseem ua rau cov chaw nyob, nrog rau kev yug menyuam lkms. Nco ntsoov khaws cov mixatures uas yuav ua rau koj cov xim zoo tagnrho. Nco ntsoov ua cov txheej txheem kho hauv qhov chaw tso pa thiab tsis txhob hnov qab txog txoj kev tiv thaiv ntawm tes thiab ua pa ntawm cov plab hnyuv siab raum.
