Ka tšehetso ea lefatše ka bophara le phano ea meaho e hahiloeng esale pele, indasteri ea kaho butle-butle e kene mehleng ea liindasteri, joale mohaho o entsoeng esale pele ke eng?Ka mantsoe a bonolo feela, mehaho e hahiloeng esale pele e tšoana le litene tsa mohaho.Likarolo tsa konkreite tse sebelisoang mohahong li entsoe esale pele fekthering esale pele, ebe li isoa setšeng sa kaho bakeng sa ho phahamisa, ho kopanya le ho kopanya ho theha mohaho.
Kamano ke efe lipakeng tsa meaho e hahiloeng esale pele le MS sealant?
Kaha meaho e entsoeng e entsoe ka lintho tse entsoeng fekthering, ha ho pelaelo hore ho na le likheo tse itseng tsa kopano pakeng tsa likaroloana.Ho tlatsa likheo tsena tsa kopano ke habohlokoa ka ho khetheha.Hajoale, ho na le mefuta e meraro ea li-sealant tsa meaho tse sebetsang hantle 'marakeng: silicone, Polyurethane le polysulfide, MS sealant e fapane le efe kapa efe ea li-sealants tsena tse tharo.Ke silicone-modified polyether sealant eo ka sebopeho e ruang litšoaneleho tsa sebopeho sa silyl terminal le sebopeho se seholo sa ketane ea polyether bond, e kopanyang melemo ea polyurethane sealant le silicone sealant mabapi le ts'ebetso, ke tataiso ea bohlokoa bakeng sa nts'etsopele ea e ncha. li-sealants lapeng le kantle ho naha.
Joale melemo ea MS sealant ke efe ha e bapisoa le li-sealant tsa meaho tse entsoeng esale pele?
1.Sekhahla se phahameng sa elasticity le matla a matla a ho falla
Hobane manonyeletso a li-slabs tsa konkreite a tla atolosoa, a fokotsehe, a fokotsehe le ho falla ka lebaka la liphetoho tsa mocheso, ho fokotseha ha konkreite, ho sisinyeha hanyenyane kapa ho rarolloa ha moaho, joalo-joalo, e le ho thibela sealant hore se senyehe le ho netefatsa tlamahano e bolokehileng le e tšepahalang. ea manonyeletso, sealant sebelisoa e tlameha E na le tekanyo e itseng ea elasticity 'me e ka ka bolokolohi ho atolosa le konteraka le ho bula le ho koala deformation ea lenonyeletso ho boloka tiiso ea lenonyeletso.Matla a ho falla a sealant e tlameha ho ba kholo ho feta phallo e lekanyelitsoeng ea seam ea boto.E ke ke ea taboha le ho tšoarella nakong ea phetoho e pheta-phetoang ea cyclic.E phunyeletse, e ka boloka le ho tsosolosa ts'ebetso ea eona ea pele le sebōpeho.Kamora ho etsa liteko, sekhahla sa ho hlaphoheloa ha elastic, matla a phalliso le modulus ea tsitsipano ea MS sealant kaofela li fetisitse litlhoko tsa maemo a naha, 'me e na le thepa e ntle ea mochini.
2. Ho hanyetsa boemo ba leholimo bo babatsehang
Ho JCJ1-2014 "Technical Regulations for Prefabricated Concrete Structures", ho boletsoe ka ho hlaka hore thepa ea ho tiisa e khethiloeng bakeng sa ho haha manonyeletso a ke ke a finyella litlhoko tsa ts'ebetso ea mochine ntle le ho thibela ho kuta le ho atolosa le ho fokotseha ha bokhoni, empa hape ho kopana le ho hanyetsa hlobo, e sa keneleng metsi, Ho aha litlhoko tsa ts'ebetso ea 'mele joalo ka ho hanyetsa boemo ba leholimo.Haeba thepa e sa khethoe hantle, sealant e tla phunyeha, e hlōlehe ho finyella phello ea ho tiisa, esita le sealant e tla hlōleha, e leng se tla ama tšireletseho ea mohaho.Sebopeho sa MS sealant ke polyether joalo ka ketane ea mantlha, hape e na le lihlopha tsa silyl tse nang le lihlopha tse sebetsang tse phekolang.E fana ka papali e felletseng ho melemo ea polyurethane sealant le silicone sealant, mme e ntlafatsa haholo ho hanyetsa boemo ba leholimo ba sealant.
3. paintability e matla, tšireletso ea tikoloho le tšilafalo e se nang tšilafalo
Hobane MS glue e na le melemo ea bobeli polyurethane sealant le silicone sealant, e rarolla mefokolo ea polysulfide sealant joalo ka lebelo le fokolang la mocheso o tlase, ho tsofala habonolo le ho thatafala, ho hloka nako e telele, le monko o matla o hlabang;ka nako e ts'oanang, sekhomaretsi sa MS ha se rate li-silicone sealants, lera la sekhomaretsi le tloaetse ho hlahisa leachate e mafura e silafatsang konkreite, lejoe le lisebelisoa tse ling tse khabisitsoeng.E na le pente e ntle le ts'ireletso ea tikoloho, e leng se khothalletsang tsoelo-pele le tsoelo-pele ea li-sealants tsa mohaho tse entsoeng esale pele.
Ka kakaretso, mehaho e entsoeng esale pele ke mokhoa oa tsoelo-pele oa mehlala ea kaho.Tsamaisong eohle ea kaho e entsoeng esale pele, khetho ea sealant e tla ba e 'ngoe ea manonyeletso a bohlokoa a amang polokeho ea moaho oohle o entsoeng esale pele.Silicone modified polyether sealant sealant——MS sealant e na le tshebetso e phethahetseng e phethahetseng mme e tla ba kgetho ya hao e molemo ka ho fetisisa.
SIWAY e ikemiselitse ho fa bareki lisebelisoa tse tala tse tsitsitseng le tse tšepahalang tsa boleng bo holimo le lits'ebeletso tse ikhethileng tsa tekheniki.Theknoloji ea ho fetola silane ea SIWAY e ntse e tsoela pele ho fana ka litharollo tsa litsebi bakeng sa ho tiisa le ho tlama meaho e entsoeng esale pele.Re labalabela ho sebetsa le uena.Mmoho, re tla thusa ntshetsopele e matla ya meaho e ahilweng esale pele lefatsheng .
