Munguva yechando, kana hunyoro uye tembiricha zvadzikira, chisimbiso chinenge chaoma uye kumhanya kwekuporesa kunononoka. Muzhizha, kana hunyoro hwakakwirira uye tembiricha yakakwira, chisimbiso chinooma uye kurapa nekukurumidza.
Maitiro ekuwana yakanakisa kurapa kuita kweimwe-chikamu silicone sealant zvigadzirwa?
Mhinduro: Imwe-chikamu condensation kurapa silicone rabha zvigadzirwa zvinorapwa uchishandisa mwando mumhepo. Kana uchirapa, kubva kunze kusvika mukati, kazhinji pasi pemamiriro e25 ° C uye 50% RH, silicone inogona kuporesa 2-3 mm pazuva, uye zvinotora mazuva anopfuura matatu kuti uwane hutano hwakanaka hwemuviri.
Kudzivirira sei tembiricha inonzi silicone sealant?
Mhinduro: Kazhinji, tembiricha yemhando yesilica gel ndeye -40 ℃-200 ℃. Iyo tembiricha yekushandisa kwenguva refu haikurudzirwe kudarika 150 ℃. Iyo tembiricha yemhando yepamusoro-yepamusoro inodzivirira sealant sesimbi tsvuku silicone ndeye -40 ℃-250 ℃. Iyo tembiricha yekushandisa kwenguva refu haipfuure 180 ℃. . Kupikisa kwekushisa kunowirirana zvakanyanya nokuti colloid yakanyatsosimbiswa.
Sei silicone adhesive sealant ine viscosity yakasiyana munguva yechando uye zhizha?
Mhinduro: Iyo viscosity yechisimbiso ichachinja nekushisa. Muzhizha, viscosity ichaderera kana tembiricha yakakwira. Munguva yechando, zvinongopesana, asi zvichava mukati mehutano hunogamuchirwa.
Nzira yekuwedzera sei kuporesa kukurumidza kwesilicone sealant?

Kana paine mavara uye hunyoro pamusoro peiyo substrate yekubatanidza, zvingakanganisa kuita kwekuisa chisimbiso?
Usati waisa chisimbiso, nzvimbo yekubatanidza inoda kucheneswa zvakakwana kuitira kuti chisimbiso chigone kunamatira zvakakwana kune yakasungirirwa pamusoro. Kana paine hunyoro kana mavara pane sealant pamusoro mushure mekurapa, kukanganisa kunenge kuri kudiki.
