Nrog kev txhawb nqa thoob ntiaj teb thiab kev txhawb nqa ntawm cov tsev prefabricated, kev lag luam kev tsim kho tau maj mam nkag mus rau lub hnub nyoog kev lag luam, yog li lub tsev prefabricated yog dab tsi? Hais yooj yim, cov tsev prefabricated zoo li cov khoom siv hauv tsev. Cov khoom siv ua vaj tse siv hauv lub tsev yog prefabricated hauv lub Hoobkas ua ntej, thiab tom qab ntawd thauj mus rau qhov chaw tsim kho rau kev tsa, kev sib txuas thiab kev sib dhos los tsim lub tsev.
Kev sib raug zoo ntawm cov tsev prefabricated thiab MS sealant yog dab tsi?
Vim tias cov tsev prefabricated yog sib sau ua ke los ntawm cov khoom ua ntej prefabricated, yeej muaj qee qhov sib dhos ntawm cov khoom. Kev sau cov sib dhos no yog qhov tseem ceeb heev. Tam sim no, muaj peb hom kev ua haujlwm siab sealant hauv khw: silicone, Polyurethane thiab polysulfide, MS sealant txawv ntawm peb hom sealant no. Nws yog ib qho silicone-modified polyether sealant uas tau txais cov yam ntxwv ntawm cov qauv terminal silyl thiab cov qauv tseem ceeb polyether bond, uas sib xyaw cov txiaj ntsig ntawm polyurethane sealant thiab silicone sealant hauv kev ua tau zoo, yog ib qho kev taw qhia tseem ceeb rau kev tsim cov sealant tshiab hauv tsev thiab txawv teb chaws.
Yog li ntawd, cov txiaj ntsig ntawm MS sealant piv rau cov sealant ua ntej tsev ib txwm muaj yog dab tsi?
1.Kev rov zoo sai thiab muaj peev xwm hloov chaw tau zoo
Vim tias cov pob qij txha ntawm cov pob zeb ua vaj tse yuav nthuav dav, sib zog, hloov pauv thiab hloov chaw vim qhov kub hloov pauv, pob zeb sib zog, me ntsis kev co lossis kev sib tsoo ntawm lub tsev, thiab lwm yam, txhawm rau tiv thaiv cov sealant kom tsis txhob tawg thiab xyuas kom muaj kev sib txuas thiab kev sib khi ntawm cov pob qij txha, cov sealant siv yuav tsum muaj qee qib ntawm elasticity thiab tuaj yeem nthuav dav thiab sib cog lus nrog qhov qhib thiab kaw deformation ntawm qhov sib koom ua ke kom tswj tau qhov sib khi ntawm qhov sib koom ua ke. Lub peev xwm hloov pauv ntawm cov sealant yuav tsum loj dua qhov hloov pauv ntawm cov laug cam. Nws yuav tsis rhuav thiab ruaj khov thaum lub sijhawm rov ua dua. Yog tias raug tho, nws tuaj yeem tswj hwm thiab rov qab ua tau zoo thiab cov duab qub. Tom qab sim, qhov nrawm rov qab elastic, lub peev xwm hloov pauv thiab tensile modulus ntawm MS sealant txhua yam dhau qhov yuav tsum tau ua ntawm lub tebchaws, thiab nws muaj cov khoom siv kho tshuab zoo.
2. Kev tiv thaiv huab cua zoo heev
Hauv JCJ1-2014 "Cov Cai Kev Siv rau Cov Qauv Pob Zeb Ua Ntej", nws tau hais meej meej tias cov ntaub ntawv sib khi xaiv rau cov pob qij txha hauv tsev yuav tsum tsis yog tsuas yog ua tau raws li cov kev cai ua haujlwm kho tshuab xwb tsis yog kev tiv thaiv shear thiab kev nthuav dav thiab kev sib cog lus deformation, tab sis kuj ua tau raws li kev tiv thaiv mildew, dej tsis nkag, Lub Tsev cov kev cai ua haujlwm lub cev xws li kev tiv thaiv huab cua. Yog tias cov khoom siv tsis raug xaiv kom zoo, cov sealant yuav tawg, ua tsis tau raws li qhov cuam tshuam ntawm kev sib khi, thiab txawm tias cov sealant yuav ua tsis tiav, uas yuav cuam tshuam rau kev nyab xeeb ntawm lub tsev. Cov qauv ntawm MS sealant yog polyether ua cov saw hlau tseem ceeb, thiab nws kuj muaj cov pab pawg silyl nrog cov pab pawg ua haujlwm kho. Nws muab kev ua si tag nrho rau qhov zoo ntawm polyurethane sealant thiab silicone sealant, thiab txhim kho qhov tiv thaiv huab cua ntawm cov sealant.
3. muaj zog pleev xim, kev tiv thaiv ib puag ncig thiab tsis muaj kuab paug
Vim tias MS kua nplaum muaj qhov zoo ntawm ob qho tib si polyurethane sealant thiab silicone sealant, nws daws qhov tsis zoo ntawm polysulfide sealant xws li qeeb qeeb qeeb hauv qhov kub thiab txias, yooj yim laus thiab tawv, tsis muaj zog, thiab muaj ntxhiab tsw qab; tib lub sijhawm, MS kua nplaum tsis zoo li silicone sealants, cov txheej nplaum yog qhov yooj yim tsim cov roj leachate uas ua rau cov pob zeb, pob zeb thiab lwm yam khoom siv kho kom zoo nkauj. Nws muaj kev pleev xim zoo thiab kev tiv thaiv ib puag ncig, uas txhawb nqa kev txhim kho thiab kev nce qib ntawm prefabricated tsev sealants.
Feem ntau, cov tsev prefabricated yog qhov kev txhim kho ntawm cov qauv kev tsim kho. Hauv tag nrho cov tsev prefabricated, kev xaiv cov sealant yuav yog ib qho ntawm cov pob qij txha tseem ceeb uas cuam tshuam rau kev nyab xeeb ntawm tag nrho cov tsev prefabricated. Silicone hloov kho polyether sealant sealant - MS sealant muaj kev ua tau zoo heev thiab yuav yog koj qhov kev xaiv zoo tshaj plaws.
SIWAY cog lus tias yuav muab cov khoom siv raw khoom zoo thiab ruaj khov rau cov neeg siv khoom. SIWAY txoj kev siv tshuab hloov kho silane txuas ntxiv muab cov kev daws teeb meem rau kev sib khi thiab kev sib txuas ntawm lub tsev prefabricated. Peb tos ntsoov yuav ua haujlwm nrog koj. Ua ke, peb yuav pab txhawb kev txhim kho ntawm cov tsev prefabricated hauv ntiaj teb.
