Sealant chinhu chekuisa chisimbiso chinokanganisa kuita chimiro chenzvimbo yekuisa chisimbiso, isiri nyore kuyerera, uye ine kumwe kunamatira. Icho chinonamira chinoshandiswa kuzadza mikaha pakati pezvinhu kuita basa rekuisa chisimbiso. Iine mabasa ekudzivirira-kudonha, kusapinda kwemvura, anti-vibration, kuvharidzira inzwi uye kupisa kupisa.
Iyo inowanzoenderana neyakaoma kana isina kuomeswa viscous zvinhu zvakaita seasphalt, resin yechisikigo kana synthetic resin, rabha rechisikigo kana synthetic rubber. Inogadzirwa neinert fillers senge talc, ivhu, kabhoni nhema, titanium dioxide uye asbestos, uyezve kuwedzera plasticizers, zvinonyungudutsa, zvinorapa, accelerators, nezvimwe.
Kurongwa kwezvisimbiso
Sealant inogona kukamurwa kuita elastic sealant, liquid sealant gasket uye mapoka matatu ekuisa chisimbiso putty.
Zvinoenderana nechikamu chemakemikari:inogona kukamurwa kuita rubber rudzi, resin rudzi, mafuta-based type uye yakasikwa polymer sealant. Iyi yemhando nzira inogona kutsvaga hunhu hwepolymer zvinhu, infer yavo tembiricha kuramba, chisimbiso uye kuchinjika kune akasiyana midhiya.
Rubber type:Rudzi urwu rwe sealant rwakavakirwa parubha. Rubber anowanzo shandiswa polysulfide rabha, silicone rabha, polyurethane rabha, neoprene rabha uye butyl rabha.
Resin mhando:Iyi mhando ye sealant yakavakirwa pane resin. Anowanzo shandiswa resin epoxy resin, unsaturated polyester resin, phenolic resin, polyacrylic resin, polyvinyl chloride resin, nezvimwe.
Mafuta-based:Rudzi urwu rwe sealant ndeye mafuta-based. Mafuta anowanzo shandiswa mafuta emuriwo akasiyana-siyana senge linseed mafuta, castor mafuta uye tung mafuta, nemafuta emhuka akadai semafuta ehove.
Classification maererano nekushandiswa:inogona kukamurwa kuva yakakwira tembiricha mhando, kutonhora kuramba mhando, kudzvanywa mhando uye zvichingodaro.
Classification maererano nefirimu-kugadzira zvivakwa:Inogona kukamurwa kuita yakaoma adhesion mhando, yakaoma peelable mhando, isina-yakaoma inonamira mhando uye semi-yakaoma viscoelastic mhando.
Classification nekushandiswa:Inogona kukamurwa kuita sealant yekuvaka, mota sealant, insulation sealant, kurongedza sealant, migodhi sealant uye mamwe marudzi.
Zvinoenderana nekuita mushure mekugadzira:inogona kukamurwa kuva marudzi maviri: kuporesa sealant uye semi-kuporesa sealant. Pakati pavo, kurapa sealant inogona kukamurwa kuita yakasimba uye inoshanduka. Rigid sealant yakasimba mushure mevulcanization kana kusimba, uye kashoma ine elasticity, haigone kukotama, uye kazhinji seams haigone kufamba; flexible sealants ari elastic uye akapfava mushure mevulcanization. Iyo isiri-kuporesa sealant ndeye yakapfava solidifying sealant iyo ichiri kuchengetedza isingaomese tackifier mushure mekuvaka uye ichienderera ichienda kune iyo yepamusoro mamiriro.
