Kana iyo silicone sealant ine matambudziko emhando, inotungamira mukudonha kwemvura, kubuda kwemhepo uye mamwe matambudziko, ayo anozokanganisa zvakanyanya kusimba kwemhepo uye kusimba kwemvura kwemagonhi nemahwindo.
Kutsemuka uye kubuda kwemvura kunokonzerwa nekutadza kwegonhi nemahwindo sealant
Saka isu tinosarudza sei chisimbiso chakakodzera chemikova nemahwindo?
1. Sarudza nemazvo zvigadzirwa zvinoenderana nezvinodiwa
Panguva yekusarudzwa kwechisimbiso, kutarisisa kunofanirwa kubhadharwa kwete chete kune chiyero chainosangana nacho, asiwo kune inowirirana nhanho yekusimuka.Displacement capacity ndiyo inonyanya kukosha index kuyera elasticity ye sealant.Iyo yakakwira iyo yekutamisa kugona, zviri nani iyo elasticity yesilicone sealant.Kugadziriswa uye kuiswa kwemagonhi nemahwindo kunofanirwa kusarudza zvigadzirwa zvine simba rekutamisa zvisingasviki 12.5 kuti ive nechokwadi chekugara kwenguva refu kwemhepo uye kuomeswa kwemvura kwemagonhi nemahwindo.
Munguva yekumisikidzwa uye kushandiswa kwemagonhi nemahwindo, iyo yekubatanidza mhedzisiro pakati peyakajairwa sealant nekongiri yesimende inowanzoipa kupfuura iyo ine aluminium profiles kana girazi remikova nemahwindo.Naizvozvo, zvakanyanya kufanira kusarudza zvigadzirwa zvinoenderana neJC/T 881 sechisimbiso chekuiswa kwemagonhi nemahwindo.
Zvigadzirwa zvine high displacement level zvine simba rakasimba rekutsungirira majoint displacement shanduko.Zvinokurudzirwa kusarudza zvigadzirwa zvine high displacement level sezvinobvira.
2. Sarudzasiliconesealant zvigadzirwa nenzira kwayo zvinoenderana nechinangwa
Yakavanzwa furemu mahwindo uye yakavanda furemu yekuvhura mafeni inoda dhizaini sealant kuti iite basa rekuumbwa kwekubatana.Silicone structural sealant inofanirwa kushandiswa, uye hupamhi hwekubatanidza kwayo uye ukobvu hunofanirwa kusangana nezvinodiwa zvekugadzira.
Panguva yekuiswa kwemagonhi nemahwindo, chisimbiso chematombo majoini kana majoini ane dombo kune rumwe rutivi chichava chisimbiso chakakosha chedombo chinosangana nechiyero cheGB/T 23261.
Fireproof sealant inonyanya kukodzera magonhi emoto uye mahwindo kana magonhi ekunze uye mahwindo ezvivakwa zvinoda kutendeseka kwemoto.
Munzvimbo dzekunyorera dzine zvakakosha zvekudzivirira mold, senge kicheni, yekugezera yehutsanana uye nzvimbo dzakasviba uye dzakanyorova, kuiswa chisimbiso kwegonhi nemahwindo majoini kunofanirwa kushandisa mold proof sealant.
3. Usasarudza silicone sealant izere nemafuta!
Parizvino, musika wakazara nenhamba yakawanda yemafuta akazadzwa gonhi uye mahwindo sealants, ayo akazadzwa nehuwandu hwakawanda hwemafuta emaminerari uye ane hurombo hwekuchembera kuramba, izvo zvinotungamira kune akawanda emhando matambudziko.
Silicone sealant yakasanganiswa nemafuta emamineral inonzi "mafuta akazadzwa silicone sealant" muindasitiri.Mineral oil ndeye saturated alkane petroleum distillation.Nekuti chimiro chayo chemolecular chakasiyana kwazvo neiyo yesilicone, kuenderana kwayo nesilicone sealant system haina kunaka, uye inotama uye ichipinda kunze kwesilicone sealant mushure menguva yakati.Naizvozvo, iyo "mafuta akazadzwa sealant" ane elasticity yakanaka pakutanga, asi mushure mekushandisa kwenguva yakati rebei, iyo yakazadzwa mineral oiri inotama uye inopinda kubva kune sealant, uye chisimbiso chinopera, kuoma, kuputika, uye kunyange kuva nedambudziko re non bonding.
Mazhinji anodhura-akaderera-silicone sealants pamusika akazadzwa nemafuta emamineral, uye zvirimo musilicone basic polymer zvakaderera pane 50%, uye zvimwe zvakatopfuura makumi maviri muzana.
Kana iyo chisimbiso chegasi rinozadza hwindo rakabatana negirazi rinodzivirira, iyo yakazara mineral oiri inotama uye ichipinda mugirazi inodzivirira, zvichikonzera kuparara kwechisimbiso butyl rabha yegirazi inodzivirira uye kuyerera kwemafuta.
Sarudza zvigadzirwa zvemhando yepamusoro sealant.Kunyangwe mutengo wechisimbiso wakatengwa padanho rekutanga wakakwira zvishoma, kuita kwayo kunogona kuchengetedzwa kwenguva yakareba pasina matambudziko emhando.Sarudza yakaderera-yakaderera-mhando "mafuta akazadzwa sealant", kunyangwe mutengo wakachipa, mutengo wekutanga wekudyara wakaderera zvishoma;Zvisinei, mushure mokunge matambudziko aitika, mari yekugadzirisa gare gare, mari yezvigadzirwa, mari yebasa, kurasikirwa kwechiratidzo, nezvimwewo panguva yekudzokorora inogona kuva kakawanda kana kunyange makumi emazana emutengo wechisimbiso pachayo;Kwete chete haina kuchengetedza mari, asi yakawedzera dambudziko rakawanda kune vashandisi.
