Adhesives thiab sealants zoo sib xws thaum nws hais txog kev sib txuas los yog sib txuas ob lossis ntau qhov chaw ua ke. Ob leeg ntawm lawv yog cov kua pasty uas tab tom ua tshuaj lom neeg los tsim kom muaj kev sib raug zoo ntawm qhov chaw nws tau thov.
Natural adhesives thiab sealants muaj nyob ib puag ncig peb thaum pib. Ob leeg tau siv ntawm no thiab nyob ntawd, los ntawm kev cob qhia hauv tsev mus rau kev tsim kho technology. Piv txwv li, ntim, ntawv tsim, tsim dav hlau, aerospace, khau, tsheb thiab khoom siv hluav taws xob yog txhua qhov kev lag luam uas xav tau cov nplaum nplaum thiab sealants.
Kev sib piv ntawm Adhesives thiab Sealants
Ob nqe lus no zoo sib xws thiab txawm hloov pauv tau hauv qee qhov xwm txheej, tab sis tseem muaj qhov sib txawv ntawm lawv hauv lub hom phiaj thiab siv zaum kawg. Adhesive yog ib yam khoom siv los tuav ob qhov chaw kom muaj zog thiab ruaj khov thaum sealant yog ib yam khoom siv los txuas ob lossis ntau qhov chaw.
Qhov qub yog qhov tseem ceeb thaum yuav tsum muaj kev sib koom ua haujlwm ntev thiab ruaj khov; tom qab ntawd yog siv los tiv thaiv cov dej los yog cov pa tawm hauv thawj zaug rau lub hom phiaj ib ntus. Lub zog ntawm sealant daim ntawv cog lus tsis yog qhov tsis muaj zog dua li ntawm cov nplaum, vim tias lawv qhov kev ua tau zoo nyob ntawm hom tshwj xeeb thiab cov ntawv thov, suav nrog cov quab yuam uas lawv tiv taus thiab lawv cov thermal zog.
Adhesives thiab sealants qhia cov cwj pwm tseem ceeb uas ua rau muaj kev sib raug zoo:
-
Fluidity: Ob leeg yuav tsum ua kom muaj tus cwj pwm zoo li cov kua dej thaum lub sij hawm thov kom muaj kev sib cuag nrog cov chaw los yog cov substrates, ua kom muaj qhov sib txawv.
-
Solidification: Ob leeg harden rau hauv ib qho khoom los yog ib nrab ntawm lub xeev los txhawb thiab tiv taus ntau yam khoom siv rau daim ntawv cog lus.
Viscosity rau Adhesives thiab Sealants
Adhesives yog categorized rau hauv natural adhesives thiab hluavtaws adhesives los ntawm lawv lub hauv paus chiv keeb. Viscosity yog noj raws li cov resistant ntawm cov kua los yog ntws. Cov nplaum nplaum thiab cov nplaum nplaum yog cov kua tsis-Newtonian. Hauv lwm lo lus, kev nyeem viscosity yog nyob ntawm qhov ntsuas qhov ntsuas.
Viscosity plays lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab kev siv cov nplaum, ua ib qho kev qhia tseem ceeb ntawm cov khoom xws li qhov ntom ntom, ruaj khov, hnyav cov ntsiab lus, sib tov tus nqi, qhov hnyav molecular, thiab tag nrho qhov sib xws los yog particle loj tis.
Lub viscosity ntawm adhesives txawv heev raws li lawv lub hom phiaj daim ntawv thov, xws li sealing los yog bonding. Adhesives yog categorized rau hauv qis, nruab nrab, thiab siab viscosity hom, txhua tus haum rau kev siv tshwj xeeb:
-
Tsawg viscosity Adhesives: Zoo tagnrho rau encapsulation, potting, thiab impregnation vim lawv muaj peev xwm ntws tau yooj yim thiab sau qhov chaw me me.
-
Nruab nrab viscosity Adhesive: Feem ntau siv rau kev sib khi thiab sib khi, muab qhov sib npaug ntawm kev khiav thiab tswj.
-
High Viscosity Adhesives: Tsim los rau cov ntaub ntawv tsis-drip lossis tsis-sagging, xws li qee yam epoxies, qhov kev ua haujlwm zoo yog qhov tseem ceeb.
Cov txheej txheem ntsuas viscosity ib txwm cia siab rau ntawm phau ntawv sampling thiab kuaj kuaj, uas yog siv sijhawm thiab siv zog ntau. Cov txheej txheem no tsis tsim nyog rau kev tswj xyuas cov txheej txheem ntawm lub sijhawm tiag tiag, vim tias cov khoom ntsuas hauv chav kuaj yuav tsis raug cuam tshuam txog cov nplaum nplaum tus cwj pwm hauv cov kab ntau lawm vim yog yam xws li lub sijhawm dhau mus, sedimentation, lossis dej aging.
Lub Lonmeterinline viscosity ntsuasmuab cov kev daws teeb meem rau lub sijhawm tiag tiag viscosity tswj, hais txog cov kev txwv ntawm cov txheej txheem ib txwm muaj thiab txhim kho cov txheej txheem tsim cov nplaum. Nws haum rau qhov kev sib txawv no nrog ntau qhov kev ntsuas dav (0.5 cP txog 50,000 cP) thiab cov duab sensor customizable, ua rau nws sib xws nrog ntau yam nplaum formulations, los ntawm qis-viscosity cyanoacrylates mus rau high-viscosity epoxy resins. Nws lub peev xwm los koom ua ke rau hauv cov kav dej, tso tsheb hlau luam, lossis cov reactors nrog cov kev xaiv yooj yim installation (xws li, DN100 flange, qhov tob tob ntawm 500mm txog 4000mm) ua kom muaj kev sib tw thoob plaws ntau qhov kev teeb tsa.
Qhov tseem ceeb ntawm Viscosity thiab Density Monitoring
Adhesive ntau lawm muaj kev sib xyaw lossis dispersing ntau cov ntaub ntawv kom ua tiav cov khoom tshwj xeeb, suav nrog tshuaj lom neeg, thermal stability, poob siab tsis kam, shrinkage tswj, yooj, serviceability, thiab lub zog ntawm cov khoom kawg.
Lonnmeter inline viscometer yog tsim los rau ntau daim ntawv thov ntawm ntau yam ntsuas cov ntsiab lus ntawm cov nplaum, nplaum, lossis cov txheej txheem tsim cov hmoov txhuv nplej siab. Nws enables inline saib xyuas ntawm viscosity thiab derivative tsis xws li ceev thiab kub. Kev teeb tsa tuaj yeem ncaj qha rau hauv lub tank sib xyaw kom nkag siab txog kev hloov pauv ntawm viscosity thiab txiav txim siab thaum twg qhov sib tov yuav tsum tau mus txog; nyob rau hauv lub tso tsheb hlau luam kom paub tseeb tias cov khoom muaj kua yog khaws cia; los yog nyob rau hauv pipelines, raws li cov kua ntws ntawm cov units.
Installation ntawm Inline Viscosity thiab Density Meters
Hauv Tanks
Kev ntsuas viscosity hauv lub tank sib xyaw rau cov kua nplaum ua kom muaj kev hloov kho sai kom ntseeg tau tias cov kua dej zoo ib yam, ua rau muaj kev ua haujlwm ntau ntxiv thiab txo cov peev txheej pov tseg.
Lub viscosity meter tuaj yeem ntsia tau rau hauv lub tank sib xyaw. Qhov ntom ntom thiab viscosity meters tsis pom zoo rau kev teeb tsa ncaj qha hauv cov tso tsheb hlau luam sib xyaw, vim tias qhov sib xyaw ua haujlwm tuaj yeem ua kom muaj suab nrov uas cuam tshuam rau kev ntsuas qhov tseeb. Txawm li cas los xij, yog tias lub tank suav nrog cov kab rov ua dua tshiab, lub ntsuas qhov ntom ntom thiab viscosity tuaj yeem txhim kho tau zoo hauv cov kav dej, raws li tau piav qhia hauv tshooj tom ntej.
Rau kev taw qhia kev teeb tsa, cov neeg siv khoom yuav tsum hu rau pab pawg txhawb nqa thiab muab cov duab kos duab lossis cov duab, qhia txog cov chaw nres nkoj thiab kev ua haujlwm xws li kub, siab, thiab xav tau viscosity.
Hauv Pipelines
Qhov chaw zoo tshaj plaws rau kev txhim kho viscosity thiab ntom ntom ntsuas hauv cov kav dej nplaum yog nyob ntawm lub luj tshib, siv qhov kev teeb tsa axial qhov chaw sojntsuam qhov ntsuas lub ntsej muag ntsib cov kua dej. Qhov no feem ntau yuav tsum tau muaj kev sojntsuam ntev ntev, uas tuaj yeem hloov kho rau qhov ntev thiab cov txheej txheem kev sib txuas raws li cov raj xa dej loj thiab qhov yuav tsum tau ua.
Qhov ntev ntawm qhov ntxig yuav tsum xyuas kom meej tias qhov ntsuas qhov ntsuas tau zoo nyob rau hauv kev sib cuag nrog cov dej ntws, kom tsis txhob muaj qhov tuag los yog nyob ruaj khov nyob ze ntawm qhov chaw nres nkoj. Kev tso lub ntsuas qhov ntsuas hauv cov yeeb nkab ncaj nraim yuav pab kom nws huv si, vim tias cov kua dej ntws los ntawm qhov kev sojntsuam tus qauv tsim, txhim khu kev ntsuas qhov tseeb thiab kev ntseeg tau.
