Kana silicone sealant iine matambudziko emhando yepamusoro, izvi zvinotungamira mukubuda kwemvura, kubuda kwemhepo nezvimwe zvinetso, izvo zvinokanganisa zvakanyanya kuoma kwemhepo uye kuoma kwemvura kwemasuo nemahwindo.
Mitswe uye kubuda kwemvura kunokonzerwa nekukundikana kwechisimbiso chemusuwo nepahwindo
Saka tingasarudza sei chivharo chakakodzera magonhi nemahwindo?
1. Sarudza zvigadzirwa zvinosangana nezvinodiwa nemazvo
Panguva yekusarudza sealant, kutarisirwa hakufanirwe kutariswa chete kune mwero wainosangana nawo, asiwo kune mwero wayo wekutama. Kugona kwekutama ndicho chiratidzo chakakosha pakuyera kusimba kwesealant. Kusimba kwekutama kwakakwira, kusimba kwesilicone sealant kuri nani. Kugadziriswa nekuiswa kwemasuo nemahwindo kunofanirwa kusarudza zvigadzirwa zvine simba rekutama kwete pasi pe12.5 kuti ive nechokwadi chekuti mhepo inogara kwenguva refu uye kusimba kwemvura kwemasuo nemahwindo.
Panguva yekuisa nekushandisa magonhi nemahwindo, kubatana pakati pechisimbiso chenguva dzose nekongiri yesimende kunowanzova kwakaipa kupfuura kune ma profiles earuminiyamu kana girazi remagonhi nemahwindo. Saka, zvakakodzera kusarudza zvigadzirwa zvinoenderana neJC/T 881 sechisimbiso chekuisa magonhi nemahwindo.
Zvigadzirwa zvine mwero wepamusoro wekutama zvine simba rakasimba rekutsungirira kuchinja kwekutama kwemajoini. Zvinokurudzirwa kusarudza zvigadzirwa zvine mwero wepamusoro wekutama zvakanyanya sezvinobvira.
2. Sarudzasiliconezvigadzirwa zve sealant nemazvo zvichienderana nechinangwa
Mahwindo efuremu akavanzika uye mafeni ekuvhura furemu akavanzika anoda chisimbiso chechimiro kuti chiite basa rekubatanidza chimiro. Chisimbiso chechimiro cheSilicone chinofanira kushandiswa, uye upamhi hwacho neukobvu zvinofanira kusangana nezvinodiwa pakugadzira.
Panguva yekuisa magonhi nemahwindo, chisimbiso chekubatanidza matombo kana majoini ane dombo kune rumwe rutivi chinofanira kuva chisimbiso chakakosha chematombo chinosangana nechiyero cheGB/T 23261.
Chivharo chisingatsvi chinonyatsokodzera magonhi nemahwindo asingatsvi kana magonhi ekunze nemahwindo ezvivakwa zvinoda kutsvinda kwemoto.
Munzvimbo dzine zvinodiwa zvakakosha zvekudzivirira chakuvhuvhu, zvakaita sekicheni, dzimba dzekugezera dzehutsanana, uye zvikamu zvakasviba uye zvakanyorova, kuvharwa kwemasuo nemahwindo kunofanirwa kushandiswa sealant inodzivirira chakuvhuvhu.
3. Usasarudza silicone sealant yakazadzwa nemafuta!
Parizvino, musika uzere nemafuta akawanda anovhara magonhi nemahwindo, ayo akazadzwa nemafuta akawanda emaminerari uye ane simba rekudzivirira kukwegura, izvo zvinozokonzera matambudziko akawanda emhando yepamusoro.
Silicone sealant yakasanganiswa nemafuta emaminerari inonzi "oil filled silicone sealant" muindasitiri. Mafuta emaminerari ndee saturated alkane petroleum distillation. Nekuti chimiro chayo chemamorekuru chakasiyana zvikuru nesilicone, inoenderana nesilicone sealant system haina kunaka, uye inotama yobuda musilicone sealant mushure menguva yakati. Saka, "oil filled sealant" ine elasticity yakanaka pakutanga, asi mushure mekushandisa kwenguva yakati, mafuta emaminerari akazadzwa anotama opinda kubva musealant, uye sealant inodzikira, inooma, inotsemuka, uye inotova nedambudziko rekusabatana.
Zvishandiso zvakawanda zvesilicone sealant zvinodhura zvishoma zviri pamusika zvakazadzwa nemafuta emaminerari, uye huwandu hwesilicone basic polymer hushoma pane 50%, uye humwe hushoma pane 20%.
Kana chisimbiso chehwindo rinozadza gasi chikasangana negirazi rinodziisa, mafuta emineral akazadzwa anotama opinda mugirazi rinodziisa, zvichikonzera kunyungudika kwerabha rebutyl rinodziisa regirazi rinodziisa uye kuyerera kwemafuta.
Sarudza zvigadzirwa zvemhando yepamusoro zve sealant. Kunyangwe mutengo we sealant wakatengwa pakutanga wakakwira zvishoma, mashandiro ayo anogona kuchengetedzwa kwenguva yakareba pasina matambudziko emhando. Sarudza "oil filled sealant" inodhura zvishoma, kunyangwe mutengo wacho wakachipa, mari yekutanga yekudyara yakaderera zvishoma; Zvisinei, mushure mekunge matambudziko aitika, mari yekugadzirisa gare gare, mari yezvigadzirwa, mari yebasa, kurasikirwa kwechiratidzo, nezvimwewo panguva yekugadzirisa patsva inogona kuva kakawanda kana kutopfuura mutengo we sealant pachayo; Hazvina kungochengetedza mari chete, asi zvakawedzera matambudziko akawanda kune vashandisi.
