TXHEEJ TXHEEM
Kev xaiv cov tshuaj sealant kom raug yuav tsum xav txog lub hom phiaj ntawm qhov sib koom ua ke, qhov loj ntawm qhov sib koom ua ke deformation, qhov loj ntawm qhov sib koom ua ke, qhov chaw sib koom ua ke, qhov chaw uas cov sib koom ua ke sib cuag, thiab cov khoom siv kho tshuab uas cov tshuaj sealant xav tau kom ua tiav. Ntawm lawv, qhov loj ntawm qhov sib koom ua ke yog txiav txim siab los ntawm hom sib koom ua ke thiab qhov loj ntawm qhov sib koom ua ke deformation.
Yuav kom paub tseeb tias cov sealant siv tau ntev thiab ua haujlwm tau zoo tshaj plaws, yuav tsum xav txog qhov kev xaiv cov sealant kom raug. Feem ntau, muaj peb kauj ruam uas yuav tsum ua kom paub tseeb tias cov sealant siv tau ntev tshaj plaws.
- 1. Tsim cov seams raws li kev tshawb fawb thiab tsim nyog raws li kev siv thiab ib puag ncig;
- 2. Txheeb xyuas cov cim qhia kev ua tau zoo uas cov sealant xav tau ua kom tau raws li qhov interface tsim;
- 3. Raws li cov ntsuas kev ua tau zoo uas tau txiav txim siab, nws raug pom zoo kom xaiv cov nplaum thiab ua qhov kev sim sib xws thiab kev nplaum kom ntseeg tau tias cov khoom xaiv tau ua tau raws li qhov yuav tsum tau ua.
Cov tshuaj nplaum rau kev tsim kho ua peb txoj haujlwm hauv qab no los ntawm cov txheej txheem sib txuas:
- 1. Muaj peev xwm sau qhov sib txawv ntawm ob lossis ntau lub substrates los tsim ib lub foob:
- 2. Tsim ib qho kev thaiv los ntawm nws tus kheej lub cev thiab kev sib txuas rau lub substrate
- 3. Tswj kom lub sealing nruj raws li nws lub neej xav tau, tej yam kev mob ua haujlwm, thiab ib puag ncig.
Cov yam tseem ceeb uas txiav txim siab qhov ua haujlwm ntawm cov sealant suav nrog nws lub peev xwm txav mus los, cov khoom siv kho tshuab, kev nplaum, kev ruaj khov, thiab qhov tsos. Cov khoom siv kho tshuab thiab cov khoom siv kho tshuab feem ntau yog hais txog cov cim xws li qhov nyuaj, elastic modulus, lub zog tensile, kev tiv thaiv kua muag, kev khov kho, thiab kev rov qab elastic. Thaum siv cov sealant, cov kev cai siv tseem ceeb uas yuav tsum tau xav txog yog lub sijhawm tsis muaj tack, lub sijhawm debonding, sagging, lub sijhawm txee (rau ob-component nplaum), extrudability, ceev kho tob, tsis ua npuas ncauj, tus nqi, xim, thiab linear shrinkage thaum kho; Tib lub sijhawm, nws yog ib qho tsim nyog los xav txog cov khoom qub ntawm cov sealant, suav nrog nws qhov kev tiv thaiv UV hluav taws xob, cov khoom siv kho tshuab kub thiab qis, thermal hydrolysis, thermal aging, thiab oxidation tsis kam.
Kev nplaum yog ib qho txheej txheem uas suav nrog kev npaj, kev siv, kev kho, thiab kev saib xyuas cov sealant. Qhov zoo ntawm kev ua tau zoo ntawm cov nplaum yog ncaj qha cuam tshuam nrog cov khoom siv sib txuas, sealant, thiab cov txheej txheem nplaum. Yog li ntawd, thaum ua kev tsim kho, yuav tsum xav txog qhov cuam tshuam ntawm peb yam. Tsuas yog los ntawm kev kho peb yam kom tsim nyog thiab sib xyaw ua ke lawv thiaj li ua tau qhov nplaum zoo tshaj plaws, thiab txhua qhov teeb meem hauv txhua qhov txuas yuav ua rau qhov nplaum tsis ua haujlwm.
Cov roj hmab silicone sealant siv rau hauv kev tsim kho feem ntau muab kev sib khi uas tiv taus huab cua thiab kev sib khi ntawm cov qauv. Ntxiv rau qhov tsim qauv zoo, cov lus qhia txog cov txheej txheem tsim kho kuj tseem yuav tsum tau ua raws li thaum lub sijhawm tsim kho.
Muaj tsib yam yuav tsum tau ua kom tiav rau kev kho qhov chaw interface thiab kev nplaum:
- Qhov chaw sib txuas yuav tsum huv, qhuav, tsis muaj hmoov av thiab te;
- Yog tias xav tau primer, nws yuav tsum tau siv rau ntawm qhov chaw huv;
- Siv cov ntaub ntawv sib txuas ua ke los yog daim kab xev nplaum raws li qhov xav tau;
- Thaum siv cov sealant, nws yog ib qho tsim nyog los sau qhov sib txawv ntawm qhov interface nrog sealant;
- Kev khawb yog kom ntseeg tau tias cov seams du, cov duab zoo, thiab kev sib cuag tag nrho nrog lub substrate.
Cov tshuaj nplaum silicone kuj tseem suav tias yog cov nplaum vim nws cov qauv tshuaj lom neeg. Cov nplaum silicone sealing yog cov tshuaj lom neeg ntuj, yog li cov kauj ruam siv kom raug yog qhov tseem ceeb heev. Vim yog kev siv OLIVIA silicone sealant hauv ntau qhov chaw sib txawv thiab lub xeev, cov lus qhia txog cov txheej txheem tsim kho tsis tuaj yeem suav tias yog cov kev pab cuam zoo thiab tiav. Kev tswj hwm zoo ntawm kev tsim kho kuj tseem yuav tsum tau ua, thiab kev sim nplaum ntawm qhov chaw yuav tsum tau ua kom ntseeg tau tias muaj zog nplaum zoo thiab txheeb xyuas cov lus qhia txog cov nplaum.
Hauv kev tswj xyuas qhov zoo ntawm kev tsim cov sealant, qhov kev sib txuas thiab kev sib haum xeeb ntawm cov sealant thiab cov khoom siv hauv paus yuav tsum tau xav txog, suav nrog cov pas nrig txhawb nqa, daim kab xev ob sab thiab lwm yam khoom siv pabcuam. Txhawm rau kom siv tau qhov kev ua tau zoo ntawm cov sealant silicone, nws yog qhov tsim nyog los xaiv cov sealant silicone sib txawv raws li qhov chaw tsim kho sib txawv, cov kev xav tau, thiab cov ntaub ntawv, thiab ua tus tswv cov txheej txheem tsim kho txheem. Cov txheej txheem tsim kho tsis raws cai feem ntau txwv tsis pub muaj kev ua tau zoo ntawm cov sealant, xws li kev ntxuav qhov chaw ntawm lub substrate, qhov ntau ntawm cov primer siv, qhov sib piv tsis raug, kev sib xyaw tsis sib xws ntawm ob lub sealant, thiab kev siv cov tshuaj ntxuav tsis raug lossis cov txheej txheem, uas tuaj yeem cuam tshuam rau qhov kev sib txuas ntawm cov sealant thiab txawm tias ua rau kev sib txuas tsis ua haujlwm, xws li kev xaiv tsis raug ua rau muaj npuas thiab xim ntawm cov sealant. Yog li kev xaiv cov sealant thiab qhov tseeb ntawm cov txheej txheem tsim kho yog qhov tseem ceeb. Los ntawm kev qhia cov haujlwm no, nws tuaj yeem pab xaiv cov sealant kom raug.
Cov Khoom Siv Dej Tsis Muaj Dej Thiab Huab Cua
Qee cov sealant uas tsis yog silicone feem ntau yuav laus zuj zus raws sijhawm thiab nyob rau hauv kev cuam tshuam ntawm cov yam tsis zoo hauv ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv lub teeb ultraviolet. Yog li ntawd, thaum xaiv cov sealant, yuav tsum xav txog lub neej ua haujlwm ntawm cov sealant. Kev sib khi dej tsis nkag yog siv los sau cov qhov sib txawv ntawm cov khoom siv kom tiv thaiv cua, nag, hmoov av, thiab lwm yam kom tsis txhob hla dhau cov qhov sib txawv. Yog li ntawd, cov sealant yuav tsum lo rau lub substrate tag nrho, kom nws thiaj li kov yeej qhov kev hloov pauv ntawm qhov sib koom ua ke los ntawm kev txav ntawm lub substrate thaum lub sijhawm txuas ntxiv lossis nias. OLIVIA silicone sealant muaj kev tiv thaiv UV zoo, tuaj yeem tswj tau qhov modulus yuav luag tas li, thiab nws qhov elasticity tsis hloov pauv hauv qhov kub ntawm -40 ℃ txog + 150 ℃.
Cov tshuaj sealant uas tsis ua haujlwm zoo feem ntau yog siv los txhaws cov qhov khoob hauv qab cov xwm txheej tsis zoo kom tiv thaiv cov hmoov av, nag, thiab cua nkag. Txawm li cas los xij, kev ntsws ntau dhau, tawv dhau sijhawm, thiab kev nplaum tsis zoo tuaj yeem cuam tshuam rau lawv txoj kev ua haujlwm. Kev sib haum xeeb, kev nplaum, thiab cov teebmeem tshuaj lom neeg yuav tsum tau xav txog thaum siv lawv.
Kev foob ntawm lub cev
Cov sealant siv rau kev kaw lub cev feem ntau lo rau ob hom substrates. Tib lub sijhawm, nws tuaj yeem kov yeej qhov kev ntxhov siab uas ntsib: kev ntxhov siab thiab kev ntxhov siab compression, kev ntxhov siab shear. Yog li ntawd, ua ntej kaw, lub zog ntawm cov pob qij txha no yuav tsum tau lees paub, kom lawv tuaj yeem qhia ntau thaum xam cov kev xav tau engineering. Lub zog ntawm cov qauv yog qhia los ntawm modulus thiab tensile zog. Cov sealant qauv yuav tsum mus txog qee qib ntawm lub zog. Lwm yam tseem ceeb rau kev kaw lub cev yog tias kev sib txuas ntawm lub foob thiab lub substrate tsis puas tsuaj dhau sijhawm. OLIVIA silicone structural sealants muaj kev ua tau zoo, lub neej ntev, thiab tsim nyog rau kev kaw lub cev.
Cov Kev Ceev Faj Rau Kev Xaiv Cov Khoom Siv Silicone Sealant Rau Kev Tsim Kho
Kev xaiv cov sealant kom raug tsis yog tsuas yog xaiv cov ntaub ntawv uas muaj cov yam ntxwv ntawm lub cev thiab tshuaj xwb, tab sis kuj xav txog hom thiab cov yam ntxwv ntawm cov khoom siv sib khi, kev tsim sib koom ua ke (suav nrog kev txhawb nqa lossis cov ntaub ntawv uas muab tso rau hauv), kev ua tau zoo uas xav tau, cov kev xav tau ntawm kev tsim khoom, thiab cov nqi tsim nyog, uas txhua yam no raug xav txog. Cov npe hauv qab no feem ntau siv hauv kev lag luam kev tsim kho los xaiv cov sealant.
