Cov nplaum thiab cov tshuaj sealant muaj feem cuam tshuam thaum nws hais txog kev nplaum lossis kev sib txuas ob lossis ntau qhov ua ke. Ob qho tib si yog cov kua nplaum uas raug ua los ntawm kev siv tshuaj lom neeg los tsim kom muaj kev sib txuas zoo ntawm qhov chaw uas nws siv.
Cov nplaum thiab cov tshuaj nplaum ntuj tsim muaj nyob ib puag ncig peb thaum pib. Ob qho tib si siv tau rau txhua qhov chaw, txij li cov chaw ua haujlwm hauv tsev mus txog rau kev tsim kho tshiab hauv thev naus laus zis. Piv txwv li, kev ntim khoom, kev tsim ntawv, kev tsim dav hlau, kev tsav dav hlau, khau, tsheb thiab cov khoom siv hluav taws xob yog txhua yam kev lag luam uas xav tau cov nplaum thiab cov tshuaj nplaum.
Kev Sib Piv Ntawm Cov Nplaum Thiab Cov Tshuaj Sealants
Ob lo lus no zoo sib xws thiab txawm tias hloov pauv tau hauv qee qhov xwm txheej, tab sis tseem muaj qhov sib txawv ntawm lawv hauv lub hom phiaj thiab kev siv zaum kawg. Cov nplaum yog ib hom tshuaj siv los tuav ob qhov chaw kom ruaj khov thiab ruaj khov thaum cov sealant yog ib yam tshuaj siv los txuas ob lossis ntau qhov chaw.
Qhov thib ib yog qhov siv tau thaum xav tau kev sib koom ua ke ntev thiab khov kho; qhov tom qab yog siv los tiv thaiv cov kua lossis roj xau hauv thawj qhov rau lub hom phiaj ib ntus. Lub zog ntawm cov sealant txoj kev sib txuas tsis yog qhov tsis muaj zog dua li cov nplaum, vim tias lawv qhov kev ua tau zoo nyob ntawm hom tshwj xeeb thiab lub hom phiaj siv, suav nrog lub zog uas lawv tiv taus thiab lawv cov khoom siv thermal.
Cov nplaum thiab cov sealant muaj cov cwj pwm tseem ceeb uas ua rau muaj kev sib txuas zoo:
-
Kev npliag dej: Ob qho tib si yuav tsum ua kom pom cov kua dej zoo li thaum lub sijhawm thov kom ntseeg tau tias muaj kev sib cuag zoo nrog cov chaw lossis cov khoom siv, ua kom tiav cov qhov sib txawv.
-
Kev khov kho: Ob qho tib si tawv mus rau hauv lub xeev khov kho lossis ib nrab khov kho kom txhawb nqa thiab tiv taus ntau yam kev thauj khoom siv rau daim ntawv cog lus.
Qhov viscosity rau cov nplaum thiab cov sealants
Cov nplaum raug muab faib ua cov nplaum ntuj thiab cov nplaum hluavtaws los ntawm lawv keeb kwm. Viscosity yog coj los ua qhov tiv taus ntawm cov kua lossis ntws. Cov nplaum viscous thiab cov sealants yog cov kua tsis-Newtonian. Hauv lwm lo lus, kev nyeem viscosity yog nyob ntawm qhov nrawm shear ntsuas.
Viscosity ua lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab kev siv cov nplaum, ua lub cim qhia tseem ceeb ntawm cov khoom xws li qhov ceev, kev ruaj khov, cov ntsiab lus ntawm cov kuab tshuaj, kev sib tov, qhov hnyav molecular, thiab kev sib xws tag nrho lossis kev faib tawm ntawm cov khoom me me.
Qhov viscosity ntawm cov nplaum sib txawv ntau heev raws li lawv lub hom phiaj siv, xws li kev kaw lossis kev sib txuas. Cov nplaum raug muab faib ua hom viscosity qis, nruab nrab, thiab siab, txhua tus haum rau cov xwm txheej siv tshwj xeeb:
-
Cov nplaum uas tsis muaj viscosity tsawgZoo tagnrho rau kev encapsulation, potting, thiab impregnation vim lawv muaj peev xwm ntws tau yooj yim thiab sau cov chaw me me.
-
Cov nplaum nplaum nruab nrab: Feem ntau siv rau kev sib txuas thiab kev sib khi, muab kev sib npaug ntawm kev ntws thiab kev tswj hwm.
-
Cov nplaum siab viscosityTsim los rau cov ntawv thov uas tsis ntws los yog tsis ntog, xws li qee cov epoxies, qhov twg kev ruaj khov ntawm cov qauv yog qhov tseem ceeb.
Cov txheej txheem ntsuas viscosity ib txwm siv kev kuaj tes thiab kev tshuaj xyuas hauv chaw kuaj mob, uas siv sijhawm ntau thiab siv zog ntau. Cov txheej txheem no tsis haum rau kev tswj hwm cov txheej txheem tiag tiag, vim tias cov khoom ntsuas hauv chaw kuaj mob yuav tsis qhia meej txog tus cwj pwm ntawm cov nplaum hauv kab ntau lawm vim muaj ntau yam xws li lub sijhawm dhau los, kev tso dej, lossis kev laus ntawm cov kua.
Lub Lonnmeterinline viscosity metermuab cov kev daws teeb meem tshiab rau kev tswj hwm viscosity tiag tiag, daws cov kev txwv ntawm cov txheej txheem ib txwm muaj thiab txhim kho cov txheej txheem tsim cov nplaum. Nws ua raws li qhov sib txawv no nrog ntau qhov ntsuas dav (0.5 cP txog 50,000 cP) thiab cov duab sensor customizable, ua rau nws sib xws nrog ntau yam nplaum, los ntawm cyanoacrylates qis-viscosity mus rau epoxy resins siab-viscosity. Nws lub peev xwm los koom ua ke rau hauv cov kav dej, cov tank, lossis reactors nrog cov kev xaiv teeb tsa yooj yim (piv txwv li, DN100 flange, qhov tob ntxig los ntawm 500mm txog 4000mm) ua kom muaj kev hloov pauv thoob plaws ntau yam kev teeb tsa ntau lawm.
Qhov Tseem Ceeb ntawm Kev Soj Ntsuam Viscosity thiab Density
Kev tsim cov nplaum suav nrog kev sib xyaw lossis kev faib ntau yam khoom siv kom ua tiav cov yam ntxwv tshwj xeeb, suav nrog kev tiv taus tshuaj lom neeg, kev ruaj khov thermal, kev tiv taus kev poob siab, kev tswj hwm kev ntsws, kev ywj pheej, kev pabcuam tau zoo, thiab lub zog hauv cov khoom kawg.
Lonnmeter inline viscometer yog tsim los rau ntau yam kev siv ntawm ntau qhov ntsuas ntawm cov nplaum, kua nplaum, lossis cov txheej txheem tsim cov hmoov txhuv nplej siab. Nws ua rau muaj kev soj ntsuam inline ntawm viscosity nrog rau cov txheej txheem derivative xws li qhov ceev thiab kub. Kev teeb tsa tuaj yeem ncaj qha rau hauv lub tank sib tov kom nkag siab txog kev hloov pauv ntawm viscosity thiab txiav txim siab thaum twg qhov kev sib tov xav tau raug ncav cuag; hauv cov tank cia khoom kom paub tseeb tias cov khoom kua tau khaws cia; lossis hauv cov kav dej, thaum cov kua ntws ntawm cov units.
Kev Teeb tsa Cov Ntsuas Viscosity thiab Density Inline
Hauv Cov Thawv Tso Tsheb Hlau
Kev ntsuas viscosity hauv lub tank sib tov rau cov kua nplaum ua rau muaj kev hloov kho sai kom ntseeg tau tias cov khoom siv kua sib xws, ua rau muaj kev ua haujlwm ntau ntxiv thiab txo cov khoom pov tseg.
Ib lub ntsuas viscosity tuaj yeem ntsia tau rau hauv lub tank sib tov. Cov ntsuas density thiab viscosity tsis pom zoo rau kev teeb tsa ncaj qha rau hauv cov tank sib tov, vim tias qhov kev sib tov yuav ua rau muaj suab nrov uas cuam tshuam rau qhov tseeb ntawm kev ntsuas. Txawm li cas los xij, yog tias lub tank muaj cov kab twj tso kua dej rov ua dua, lub ntsuas density thiab viscosity tuaj yeem ntsia tau zoo hauv cov kav dej, raws li tau piav qhia hauv ntu tom ntej.
Yog xav tau kev qhia txog kev teeb tsa, cov neeg siv khoom yuav tsum tiv tauj pab pawg txhawb nqa thiab muab cov duab kos lossis cov duab ntawm lub tank, qhia meej txog cov chaw nres nkoj thiab cov xwm txheej ua haujlwm xws li kub, siab, thiab viscosity xav tau.
Hauv Cov Kav Dej
Qhov chaw zoo tshaj plaws rau kev teeb tsa cov ntsuas viscosity thiab density hauv cov kav dej kua nplaum yog ntawm lub luj tshib, siv qhov chaw teeb tsa axial qhov twg lub ntsuas qhov ntsuas tig mus rau qhov ntws ntawm cov kua. Qhov no feem ntau xav tau lub ntsuas ntev, uas tuaj yeem hloov kho rau qhov ntev ntawm qhov ntxig thiab kev sib txuas ntawm cov txheej txheem raws li qhov loj me thiab qhov yuav tsum tau ua ntawm cov kav dej.
Qhov ntev ntawm qhov ntxig yuav tsum ua kom lub cuab yeej ntsuas tau sib cuag tag nrho nrog cov kua dej ntws, zam kom tsis txhob muaj thaj chaw tuag lossis tsis txav ze ntawm qhov chaw teeb tsa. Kev tso lub cuab yeej ntsuas rau hauv ib txoj yeeb nkab ncaj pab kom nws huv, vim tias cov kua dej ntws hla tus qauv tsim uas yooj yim dua, ua rau kev ntsuas raug thiab kev ntseeg siab dua.
