A. Tsawg ib puag ncig cov av noo
Tsawg ib puag ncig cov av noo ua rau qeeb kho ntawm lub sealant.Piv txwv li, nyob rau lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg nyob rau sab qaum teb kuv lub teb chaws, qhov txheeb ze av noo ntawm huab cua tsis tshua muaj, qee zaum txawm tias nyob ib puag ncig 30% RH rau lub sijhawm ntev.
Kev daws: Sim xaiv kev tsim kho raws caij nyoog rau qhov teeb meem kub thiab av noo.
B. Ib puag ncig kub sib txawv (qhov kub thiab txias ntau dhau ntawm tib hnub lossis ob hnub uas nyob ib sab)
Thaum lub sij hawm tsim kho, chav tsev tsim kho cia siab tias qhov kev kho ceev ntawm lub sealant yuav tsum ceev li sai tau, thiaj li txo tau qhov muaj feem cuam tshuam los ntawm lwm yam.Txawm li cas los xij, muaj cov txheej txheem rau sealant curing, uas feem ntau siv ob peb hnub.Yog li ntawd, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawmFeem ntau, huab cua (feem ntau yog kub thiab av noo) yog xaiv rau kev tsim kho ntawm qhov kub thiab txias thiab tsim nyog rau kev tsim kho (tsuas yog qhov kub thiab av noo rau lub sijhawm ntev).
Kev daws: Sim xaiv lub caij thiab lub sijhawm nrog qhov sib txawv ntawm qhov kub me me rau kev tsim kho, xws li kev tsim huab.Tsis tas li ntawd, lub sijhawm kho ntawm silicone huab cua-resistant sealant yuav tsum luv luv, uas tseem tuaj yeem ua kom ntseeg tau tias lub sealant yuav tsis raug tshem tawm los ntawm lwm yam sab nraud quab yuam thaum lub sij hawm kho kom cov kua nplaum tuaj yeem tshwm sim.
C. Cov khoom siv vaj huam sib luag, qhov loj thiab cov duab
Cov substrates sib txuas los ntawm sealants feem ntau yog iav thiab txhuas.Cov substrates no yuav nthuav dav thiab cog lus nrog qhov kub thiab txias raws li qhov kub thiab txias hloov, uas yuav ua rau cov kua nplaum yuav raug txias ncab thiab kub nias.
Lub coefficient ntawm linear expansion kuj hu ua coefficient ntawm linear expansion.Thaum qhov kub ntawm cov khoom hloov pauv los ntawm 1 degree Celsius, qhov sib piv ntawm qhov hloov ntawm nws qhov ntev mus rau nws qhov ntev ntawm qhov qub kub (tsis tas li 0 ° C) yog hu ua "coefficient of linear expansion".Chav tsev yog 1 / ℃, thiab lub cim yog αt.Nws txhais tau tias yog αt = (Lt-L0) / L0∆t, uas yog, Lt = L0 (1 + αt∆t), qhov twg L0 yog thawj qhov loj ntawm cov khoom, Lt yog qhov loj ntawm cov khoom ntawm t ℃, thiab ∆t yog qhov kub sib txawv.Raws li pom nyob rau hauv cov lus saum toj no, qhov loj dua qhov loj ntawm aluminium phaj, qhov pom tseeb dua qhov tshwm sim ntawm cov kua nplaum hauv cov kua nplaum sib koom ua ke.Qhov sib koom deformation ntawm tshwj xeeb-zoo li aluminium phaj yog loj dua li ntawm lub tiaj tiaj aluminium phaj.
Kev daws: Xaiv cov phaj aluminium thiab iav nrog me me linear expansion coefficient, thiab them nyiaj tshwj xeeb rau kev taw qhia ntev (sab luv) ntawm cov ntawv txhuas.Kev siv hluav taws xob zoo los yog kev tiv thaiv ntawm aluminium phaj, xws li npog cov phaj txhuas nrog lub hnub ci zaj duab xis.Lub tswv yim "secondary sizing" kuj siv tau rau kev tsim kho.
D. Kev cuam tshuam ntawm sab nraud quab yuam
Cov tsev siab siab yuav raug cuam tshuam los ntawm huab cua.Yog tias cua muaj zog, nws yuav ua rau huab cua ua kua nplaum.Feem ntau cov nroog hauv peb lub tebchaws yog nyob rau thaj tsam monsoon, thiab cov ntaub thaiv phab ntsa vaj tse yuav sway me ntsis vim muaj cua sab nraud, ua rau muaj kev hloov pauv ntawm qhov dav ntawm cov pob qij txha.Yog tias cov kua nplaum tau siv thaum cua muaj zog, lub sealant yuav bulge vim yog qhov hloov ntawm lub phaj ua ntej nws yuav kho tag nrho.
Kev daws: Ua ntej siv cov kua nplaum, txoj hauj lwm ntawm cov ntawv txhuas yuav tsum tau kho kom ntau li ntau tau.Nyob rau tib lub sijhawm, qee txoj hauv kev kuj tuaj yeem siv los ua kom tsis muaj zog ntawm sab nraud quab yuam ntawm daim ntawv txhuas.Nws yog txwv tsis pub siv cov kua nplaum nyob rau hauv cov xwm txheej ntawm cua ntau dhau.
E. kev tsim kho tsis raug
1. Cov kua nplaum sib txuas thiab cov khoom siv hauv paus muaj cov av noo thiab los nag;
2. Cov nplaum nplaum yog raug khawb thaum lub sij hawm tsim kho / qhov tob ntawm qhov ua npuas ncauj yog txawv;
3. Cov ntaub nplaum ua npuas ncauj / ob daim kab xev tsis yog flattened ua ntej sizing, thiab nws bulged me ntsis tom qab sizing.Nws pom bubbling phenomenon tom qab sizing.
4. Cov nplaum nplaum yog xaiv tsis raug, thiab cov npuas dej tsis tuaj yeem yog cov nplaum nplaum uas tsis tshua muaj, uas yuav tsum ua raws li cov lus qhia tshwj xeeb;
5. Lub thickness ntawm lub sizing tsis txaus, nyias nyias, los yog lub thickness ntawm lub sizing yog tsis sib npaug;
6. Tom qab kev sib txuas ntawm cov substrate yog siv, cov kua nplaum tsis khov thiab txav mus tag, ua rau kev hloov pauv ntawm cov substrates thiab tsim cov hlwv.
7. Cov kua nplaum uas muaj cawv yuav ua rau lub ntsej muag thaum siv nyob rau hauv lub hnub (thaum lub substrate saum npoo kub siab).
Kev daws: Ua ntej kev tsim kho, xyuas kom meej tias txhua yam ntawm cov substrates yog nyob rau hauv kev tsim kho ntawm huab cua-resistant sealant teeb meem, thiab qhov kub thiab av noo nyob rau hauv ib puag ncig kuj nyob rau hauv qhov tsim nyog ntau yam (pom zoo kev tsim kho).
