Nrog rau thoob ntiaj teb kev txhawb nqa thiab kev txhawb nqa ntawm cov tsev prefabricated, kev tsim kho kev lag luam tau maj mam nkag mus rau lub hnub nyoog ntawm kev lag luam, yog li dab tsi yog lub tsev prefabricated?Cias muab, cov tsev prefabricated zoo li lub tsev thaiv.Cov khoom siv pob zeb siv hauv lub tsev yog prefabricated nyob rau hauv lub Hoobkas ua ntej, thiab tom qab ntawd thauj mus rau qhov chaw tsim kho rau hoisting, splicing thiab sib dhos los tsim lub tsev.
Kev sib raug zoo ntawm cov tsev prefabricated thiab MS sealant yog dab tsi?
Vim hais tias cov tsev prefabricated tau sib sau ua ke los ntawm lub Hoobkas prefabricated Cheebtsam, muaj inevitably qee qhov sib dhos ntawm cov khoom.Filling cov qhov sib dhos no yog qhov tseem ceeb tshwj xeeb.Tam sim no, muaj peb hom kev ua tau zoo hauv tsev sealants nyob rau hauv kev ua lag luam: silicone, Polyurethane thiab polysulfide, MS sealant txawv ntawm ib qho ntawm peb cov sealants.Nws yog cov khoom siv silicone-hloov polyether sealant uas tau txais cov yam ntxwv ntawm lub davhlau ya nyob twg silyl qauv thiab cov saw hlau tseem ceeb polyether daim ntawv cog lus, uas sib txuas cov txiaj ntsig ntawm polyurethane sealant thiab silicone sealant nyob rau hauv cov nqe lus ntawm kev ua tau zoo, yog ib qho tseem ceeb ntawm kev tsim kho tshiab. sealants hauv tsev thiab txawv teb chaws.
Yog li dab tsi yog qhov zoo ntawm MS sealant piv nrog cov tsoos prefabricated tsev sealants?
1.Siab elastic rov qab tus nqi thiab muaj zog xaav muaj peev xwm
Vim tias cov pob qij txha ntawm cov pob zeb pob zeb yuav raug nthuav tawm, kev cog lus, deformation thiab kev hloov pauv vim qhov kub hloov pauv, pob zeb shrinkage, me ntsis vibration lossis kev sib haum xeeb ntawm lub tsev, thiab lwm yam, txhawm rau tiv thaiv lub sealant los ntawm kev tawg thiab ua kom muaj kev ruaj ntseg thiab txhim khu kev qha kev sib txuas thiab sealing. ntawm cov pob qij txha, lub sealant siv yuav tsum Nws muaj ib tug tej yam degree ntawm elasticity thiab muaj peev xwm nthuav dav thiab cog lus nrog qhib thiab kaw deformation ntawm lub pob qij txha los tswj lub sealing ntawm lub pob qij txha.Lub peev xwm hloov chaw ntawm lub sealant yuav tsum muaj ntau dua li qhov txheeb ze ntawm lub rooj tsavxwm seam.Nws yuav tsis tsim kua muag thiab ruaj khov thaum rov ua dua cyclic deformation.Punctured, nws tuaj yeem tswj tau thiab kho nws qhov kev ua tau zoo thiab zoo li qub.Tom qab kev sim, qhov elastic rov qab tus nqi, kev hloov pauv muaj peev xwm thiab tensile modulus ntawm MS sealant tag nrho dhau lub teb chaws tus qauv, thiab nws muaj cov khoom zoo.
2. Cov huab cua tiv taus zoo heev
Nyob rau hauv JCJ1-2014 "Technical Regulations for Prefabricated Concrete Structures", nws tau hais meej meej tias cov khoom sib khi uas xaiv rau lub tsev pob qij txha yuav tsum tsis yog tsuas yog ua tau raws li cov txheej txheem kev ua tau zoo ntawm cov khoom siv uas tsis yog shear resistance thiab expansion thiab contraction deformation capabilities, tab sis kuj ua tau raws li mildew resistance, waterproof, Tsim lub cev kev ua tau zoo raws li huab cua tsis kam.Yog tias cov khoom tsis raug xaiv kom raug, lub sealant yuav tawg, tsis ua tiav cov nyhuv sealing, thiab txawm tias lub 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 tseem ceeb, thiab nws kuj muaj silyl pawg nrog kho cov pab pawg ua haujlwm.Nws muab tag nrho kev ua si rau qhov zoo ntawm polyurethane sealant thiab silicone sealant, thiab zoo heev txhim kho huab cua tsis kam ntawm sealant.
3. muaj zog paintability, ib puag ncig tiv thaiv 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-kub curing ceev, yooj yim aging thiab hardening, tsis muaj durability, thiab muaj zog pungent tsw;Nyob rau tib lub sijhawm, MS kua nplaum tsis zoo li silicone sealants, cov nplaum txheej yog yooj yim los tsim oily leachate uas paug pob zeb, pob zeb thiab lwm yam khoom siv zoo nkauj.Nws muaj cov xim zoo nkauj thiab kev tiv thaiv ib puag ncig, uas txhawb kev txhim kho thiab kev vam meej ntawm prefabricated lub tsev sealants.
Feem ntau, cov tsev prefabricated yog cov qauv kev tsim kho.Nyob rau hauv tag nrho lub tsev prefabricated system, kev xaiv ntawm sealant yuav yog ib qho ntawm cov pob qij txha tseem ceeb uas cuam tshuam rau kev nyab xeeb ntawm tag nrho lub tsev prefabricated.Silicone hloov polyether sealant sealant-MS sealant muaj kev ua tau zoo heev thiab yuav yog qhov koj xaiv zoo tshaj.
SIWAY tau cog lus los muab cov neeg siv khoom ruaj khov thiab txhim khu kev qha zoo raw cov ntaub ntawv thiab cov kev pabcuam customized.SIWAY's silane hloov kho tshuab txuas ntxiv muab cov kev daws teeb meem rau lub tsev prefabricated sealing thiab sib txuas.Peb tos ntsoov yuav ua haujlwm nrog koj.Ua ke, peb yuav pab txhawb kev loj hlob ntawm cov tsev prefabricated hauv ntiaj teb.
