Ndi chithandizo chapadziko lonse lapansi ndi kukwezedwa kwa nyumba zomangidwa kale, makampani omanga pang'onopang'ono alowa m'nthawi ya mafakitale, ndiye nyumba yomangidwa kale ndi chiyani?Mwachidule, nyumba zomangidwa kale zili ngati midadada yomangira.Zigawo za konkire zomwe zimagwiritsidwa ntchito m'nyumbayi zimapangidwira kale mufakitale, ndiyeno zimatumizidwa kumalo omangapo kuti zikweze, kuphatikizira ndi kugwirizanitsa kupanga nyumbayo.
Kodi pali ubale wotani pakati pa nyumba zomangidwa kale ndi MS sealant?
Chifukwa chakuti nyumba zomangidwa kale zimasonkhanitsidwa kuchokera ku zida zopangira fakitale, mosakayikira pali mipata yolumikizirana pakati pa zigawo zina.Kudzaza mipata yamagulu awa ndikofunikira kwambiri.Pakali pano, pali mitundu itatu ya zosindikizira zomangira zogwira ntchito kwambiri pamsika: silicone, Polyurethane ndi polysulfide, MS sealant ndi yosiyana ndi iliyonse yazitsulo zitatuzi.Ndi silicone-modified polyether sealant yomwe imatengera mawonekedwe a terminal silyl kapangidwe kake ndi kapangidwe kake kakang'ono ka polyether chomangira, chomwe chimaphatikiza zabwino za polyurethane sealant ndi silikoni sealant potengera magwiridwe antchito, ndi njira yofunikira pakukula kwatsopano. zosindikizira kunyumba ndi kunja.
Ndiye ubwino wa MS sealant ndi uti poyerekeza ndi zosindikizira zachikhalidwe zomangidwa kale?
1.Kuchuluka kwa elasticity kuchira komanso mphamvu yamphamvu yosamuka
Chifukwa zolumikizira za konkriti zidzakulitsidwa, kuchepetsedwa, kusinthika ndi kusamuka chifukwa cha kusintha kwa kutentha, kutsika kwa konkire, kugwedezeka pang'ono kapena kukhazikika kwa nyumbayo, ndi zina zotero, kuti aletse chosindikizira kuti chisaphwanyike ndikuwonetsetsa kuti kulumikizana kotetezeka komanso kodalirika komanso kusindikiza. wa zolumikizira, chosindikizira ntchito ayenera Kumakhala ndi mlingo wina wa elasticity ndipo akhoza momasuka kukula ndi mgwirizano ndi kutsegula ndi kutseka mapindikidwe olowa kuti apitirize kusindikiza cholumikizira.Kukhoza kusuntha kwa chosindikizira kuyenera kukhala kwakukulu kuposa kusamutsidwa kwapagulu kwa msoko.Sichidzang'ambika ndikukhala cholimba panthawi yobwerezabwereza.Ikakhometsedwa, imatha kusunga ndikubwezeretsa magwiridwe ake apachiyambi ndi mawonekedwe ake.Pambuyo kuyezetsa, zotanuka kuchira mlingo, kusamutsidwa mphamvu ndi kumakoka modulus wa MS sealant zonse kuposa zofunika dziko muyezo, ndipo ali katundu wabwino makina.
2. Kukana kwanyengo kwabwino kwambiri
Mu JCJ1-2014 "Technical Regulations for Prefabricated Concrete Structures", zimanenedwa momveka bwino kuti zida zosindikizira zomwe zimasankhidwa kuti zigwirizane ndi zomangamanga sizidzangokwaniritsa zofunikira zamakina kuposa kukana kukameta ubweya ndi kukulitsa ndi kusinthika kwapang'onopang'ono, komanso kukumana ndi mildew kukana, madzi, Kumanga zofunikira pakuchita zinthu monga kukana nyengo.Ngati zinthuzo sizinasankhidwe bwino, chosindikiziracho chidzasweka, kulephera kukwaniritsa kusindikiza, ndipo ngakhale chosindikizira chidzalephera, chomwe chidzakhudza chitetezo cha nyumbayo.Mapangidwe a MS sealant ndi polyether monga unyolo waukulu, ndipo ilinso ndi magulu a silyl okhala ndi magulu ochiritsa.Imapereka kusewera kwathunthu pazabwino za polyurethane sealant ndi silicone sealant, ndipo imathandizira kwambiri kukana kwanyengo kwa chosindikizira.
3. paintability wamphamvu, kuteteza chilengedwe ndi kuipitsidwa-free
Chifukwa MS guluu ali ndi ubwino wa polyurethane sealant ndi silikoni sealant, amathetsa zofooka za polysulfide sealant monga pang'onopang'ono otsika kutentha kuchiritsa liwiro, kukalamba mosavuta ndi kuumitsa, kusowa durability, ndi wamphamvu fungo lamphamvu;nthawi yomweyo, MS glue sakonda zosindikizira za silicone, zomatira zimakhala zosavuta kupanga leachate yamafuta yomwe imawononga konkire, miyala ndi zinthu zina zokongoletsera.Ili ndi utoto wabwino komanso kuteteza chilengedwe, zomwe zimalimbikitsanso chitukuko ndi kupita patsogolo kwa zosindikizira zomangira zomangira.
Kawirikawiri, nyumba zomangidwa kale ndizomwe zimapangidwira zitsanzo zomanga.Mu dongosolo lonse la zomangamanga, kusankha kwa sealant kudzakhala chimodzi mwazinthu zofunikira zomwe zimakhudza chitetezo cha nyumba yonse yokonzedweratu.Silicone modified polyether sealant sealant - MS sealant ili ndi magwiridwe antchito abwino kwambiri ndipo idzakhala chisankho chanu chabwino kwambiri.
SIWAY yadzipereka kupatsa makasitomala zinthu zokhazikika komanso zodalirika zapamwamba komanso ntchito zaukadaulo zosinthidwa makonda.Ukadaulo wosintha silane wa SIWAY ukupitilizabe kupereka mayankho aukadaulo pa kusindikiza ndi kumanga nyumba.Tikuyembekezera kugwira nanu ntchito.Pamodzi, tithandizira chitukuko champhamvu cha nyumba zomangidwa kale padziko lonse lapansi .
