Vanhu vazhinji vanogona kunge vakasangana nezviitiko izvi: Kunyangwe mahwindo akavharwa, mvura ichiri kunaya ichipinda mumba uye muridzo wemotokari dziri mumugwagwa uri pasi unogona kunzwika zvakanaka kumba. Izvi zvinogona kunge zviri kukundikana kwechisimbiso chemusuwo nehwindo!
Kunyangwe zvakadarochisimbiso chesiliconeichinhu chinobatsira chete mukugadzirwa kwemahwindo, zvichireva kuti mutengo wayo unenge wakaderera, inoita basa rakakosha mukushanda kwemahwindo, kunyanya mukusapinda mvura, kusapinda mhepo, kuputira mafuta, kuputira ruzha, nezvimwewo. Hazvifanirwe kurerutswa. Kana silicone sealant iine matambudziko emhando yepamusoro, inokonzera matambudziko akadai sekubuda kwemvura uye kubuda kwemhepo, izvo zvinokanganisa zvakanyanya kuoma kwemhepo uye kuoma kwemvura kwemasuo nemahwindo.
Saka unoshandisa silicone yerudzii pamahwindo?
1. Sarudza zvigadzirwa zvinosangana nezvinodiwa nemazvo
Mukusarudza silicone sealant, pamusoro pezvinodiwa zvainosangana nazvo, kutarisirwa kunofanirawo kupihwa kune nhanho yayo yekutama inoenderana. Kugona kwekutama ndicho chiratidzo chakakosha chekuyera kusimba kwesealant. Kusimba kwekutama kwakakwira, kusimba kwesealant kuri nani. Pakugadzirisa nekugadzika mahwindo, zvigadzirwa zvine simba rekutama risingasviki 12.5 zvinofanirwa kusarudzwa kuti zvive nechokwadi chekuti mahwindo anogara kwenguva refu achibata mhepo uye anodzivirira mvura.
Panguva yekuisa nekushandisa mahwindo, kubatana pakati pezvisungo zvesimbi nekongiri yesimende kunowanzova kwakaipa kupfuura kune ma profiles earuminiyamu kana magirazi emagonhi nemahwindo. Saka, zvakakodzera kushandisa chisungo chinoshandiswa pakuisa mahwindo muChina kutevedzera JC/T 881.
Zvigadzirwa zvine mwero wekutamiswa kwakawanda zvinokwanisa kutsungirira shanduko mukutama kwemajoini. Zvinokurudzirwa kusarudza zvigadzirwa zvine mwero wekutamiswa kwakawanda sezvinobvira.
2. Sarudza zvigadzirwa zve sealant nemazvo zvichienderana nekushandisa
Mahwindo efuremu yakavanzika uye mafeni ekuvhura furemu yakavanzika anoda kuti chisimbiso chechimiro chiite basa rekubatanidza chimiro. Chisimbiso chechimiro cheSilicone chinofanira kushandiswa, uye upamhi hwacho neukobvu zvinofanira kusangana nezvinodiwa pakugadzira.
Mukuita kwekuisa magonhi nemahwindo, chisimbiso chinoshandiswa pakubatanidza matombo kana majoini ane dombo kudivi rimwe chete chinofanira kunge chiri chisimbiso chakakosha chematombo chinosangana nezvinodiwa neGB/T 23261.
Kune magonhi nemahwindo asingatsvi kana magonhi ekunze echivako anoda kuti atsvike, zvakakodzera kushandisa zvinovhara moto.
Kune nzvimbo dzinoshandiswa dzine zvinodiwa zvakakosha zvekudzivirira chirwere chefungus, zvakaita sekicheni, dzimba dzekugezera nenzvimbo dzine rima uye hunyoro, zvinovhara magonhi nemahwindo zvinofanirwa kushandiswa.
3. Usasarudza silicone sealants yakazara nemafuta!
Parizvino, kune zvakawanda zvinovhara magonhi nemahwindo zvakazara nemafuta zviri pamusika. Zvigadzirwa izvi zvakazara nemafuta akawanda emineral uye hazvina simba rekukwegura, izvo zvinozokonzera matambudziko akawanda emhando yepamusoro.
Zvivharo zveSilicone zvakasanganiswa nemafuta emineral zvinozivikanwa muindasitiri iyi se "oil-extended silicone sealants". Mafuta emineral imhando yealkane petroleum distillate yakaguta. Nekuti chimiro chayo chemamorekuru chakasiyana zvikuru nechasilicone, hachina kuenderana zvakanaka nesilicone sealant system, uye chinotama nekupinda kubva musilicone sealant mushure menguva yakati. Nokudaro, "oil-filled sealant" ine elasticity yakanaka pakutanga, asi mushure menguva yekushandiswa, mafuta emineral akazadzwa anotama nekupinda kubva musealant, uye sealant inodzikira, inooma, inotsemuka, uye pane dambudziko rekusabatana.
