Vanhu vakawanda vangave vakava nezvinoitika izvi: Kunyange zvazvo mahwindo akavharwa, mvura ichiri kunaya ichipinda mumusha uye muridzo wemotokari mumugwagwa uri pasi unogona kunzwika zvakajeka pamusha.Izvi zvinogona kunge zviri kutadza kwegonhi nehwindo sealant!
Nyangwesilicone sealantinongova chinhu chekubatsira mukugadzirwa kwemahwindo, kuverenga kune chikamu chiduku chemari, inoita basa rinokosha zvikuru mukushanda kwemahwindo, kunyanya mukudzivirira mvura, kuvhara mhepo, kupisa kwekushisa, kuvhara inzwi, nezvimwewo. kusakoshesa.Kana iyo silicone sealant ine matambudziko emhando, inokonzeresa matambudziko akadai sekudonha kwemvura uye kubuda kwemhepo, izvo zvinokanganisa zvakanyanya kusimba kwemhepo uye kusimba kwemvura kwemagonhi nemahwindo.
Saka rudzii rwesilicone yaunoshandisa mahwindo?
1. Sarudza nemazvo zvigadzirwa zvinoenderana nezvinodiwa
Mukusarudza maitiro esilicone sealant, mukuwedzera kune zviyero zvaanosangana nazvo, kutarisisa kunofanirwa kubhadharwa kune yayo inoenderana yekutamisa nhanho.Displacement capacity ndiyo inonyanya kukosha chiratidzo kuyera elasticity ye sealant.Iyo yakakwira iyo simba rekutamisa, zviri nani kunyungudika kweiyo sealant.Nekugadzirisa uye kuiswa kwemahwindo, zvigadzirwa zvine simba rekutamisa zvisingasviki 12.5 zvinofanira kusarudzwa kuti ive nechokwadi chekugara kwenguva refu kwemhepo uye kuvhara kwemvura kwemahwindo.
Munguva yekuiswa uye kushandiswa kwemahwindo, iyo yekubatanidza mhedzisiro pakati peakajairwa sealants nekongiri yesimende inowanzoipa kupfuura iyo ine aluminium profiles kana girazi remikova nemahwindo.Naizvozvo, zvinonyanya kukosha kushandisa chisimbiso chinoshandiswa pakuisa hwindo muChina kutevedzera JC/T 881.
Zvigadzirwa zvine mazinga ekutamisa zvakanyanya zvinokwanisa kushingirira shanduko mukufambiswa kwemajoini.Zvinokurudzirwa kusarudza zvigadzirwa zvine mazinga ekutamisa zvakanyanya sezvinobvira.
2. Kururamisa sarudza sealant zvigadzirwa maererano nekushandiswa
Yakavanzika furemu mahwindo uye yakavanzika furemu yekuvhura mafeni inoda structural sealant kuti iite basa rekubatanidza.Silicone structural sealant inofanirwa kushandiswa, uye hupamhi hwekubatanidza uye ukobvu hunofanirwa kusangana nezvinodiwa zvekugadzira.
Mukuita kwekumisikidzwa kwegonhi nehwindo, chisimbiso chinoshandiswa matombo majoini kana majoini ane dombo kune rimwe divi chinofanira kunge chiri chisimbiso chakakosha chedombo chinosangana neGB/T 23261 standard.
Pamagonhi nemahwindo asingapindi moto kana magonhi ekunze nemahwindo ekunze zvinoda kuperera pamoto, zvinonyanya kufanira kushandisa zvinovhara moto.
Kune nzvimbo dzekunyorera dzine zvakakosha zvekudzivirira ukuru, senge kicheni, imba yekugezera uye nzvimbo dzine rima uye dzine hunyoro, zvisimbiso zvinodzivirira mildew zvinofanirwa kushandiswa kuvhara magonhi nemahwindo.
3. Usasarudza mafuta akazara-silicone sealants!
Parizvino, kune akawanda akazadzwa nemafuta egonhi nemahwindo sealants pamusika.Izvi zvigadzirwa zvakazadzwa nehuwandu hwemafuta emaminerari uye zvine hurombo hwekuchembera kuramba, izvo zvinozotungamira kune akawanda emhando matambudziko.
Silicone sealants akaiswa nemineral oil anozivikanwa muindasitiri se "oiri-yakawedzerwa silicone sealants".Mineral oil is saturated alkane petroleum distillate.Nekuti chimiro chayo chemolecular chakasiyana kwazvo neiyo yesilicone, haina kuenderana neiyo silicone sealant system, uye inotama uye inopinda mukati meiyo silicone sealant mushure menguva yakati.Naizvozvo, "mafuta-akazadzwa sealant" ane elasticity yakanaka pakutanga, asi mushure menguva yekushandiswa, iyo yakazara mineral oiri inotama uye inopinda kubva kune chisimbiso, uye chisimbiso chinodonha, chinoomesa, chinotsemuka, uye pane kunyange dambudziko re non-bonding.
