Girazi sealant
Girazi sealant chinhu chinoshandiswa kubatanidza uye kuvhara marudzi akasiyana egirazi nezvimwe zvigadziko.Iyo inonyanya kukamurwa kuita mapoka maviri: silicone sealant uye polyurethane sealant (PU).Silicone sealant yakakamurwa kuita acid sealant, neutral sealant, structural sealant, etc. Polyurethane sealant yakakamurwa kuita adhesive sealant uye sealant.
Kunyatsoshandiswa kwegirazi sealant
1.Inokodzera kuvharwa kusingachinjiki kwemamiriro ekunze emadziro eketeni akasiyana-siyana, kunyanya inokurudzirwa kuvharwa kwegirazi madziro eketeni, aluminium-plastic panel curtain wall, uye dombo rakaomarara.
2. Seam sealing pakati pesimbi, girazi, aluminium, ceramic tiles, organic glass uye girazi rakavharwa.
3. Joint chisimbiso chekongiri, simende, masonry, dombo, marble, simbi, huni, anodized aluminium uye pendi yealuminium pendi.Muzviitiko zvakawanda hapana chikonzero chekushandisa primer.
4. Iyo ine yakanakisa kupikisa mamiriro ekunze akadai seozone resistance uye ultraviolet resistance, uye ine hupenyu hurefu hwebasa.
Sealant sumo
Sealant inoreva chinhu chekuisa chisimbiso chinokanganiswa nechimiro chenzvimbo yekuvharisa, isiri nyore kuyerera, uye ine rimwe simba rekunamira.Iyo inowanzobva pane yakaoma kana isina kuomeswa viscous zvinhu zvakadai seasphalt, natural resin kana synthetic resin, natural rubber kana synthetic rubber, uye yobva yawedzera inert fillers, inoteverwa ne plasticizers, solvents, kuporesa agents, accelerators, etc. Kumirira kugadzirwa. .Sealants inosiyaniswa nekuita.Basa ravo chete nderekusunga.Chisimbiso chinodzivirira mamiriro ekunze, silicone structural sealant, uye polyurethane sealant zvese zvine mabasa ekuisa chisimbiso, asi zvinewo mamwe mabasa akakosha, akadai sesimba rekubatanidza uye kumira kwakanaka kwemamiriro ekunze.
Kunyatsoshandiswa kwema sealants
1. Zvinoenderana nemhando, inogona kukamurwa kuita chisimbiso chekuvaka, mota sealant, insulation sealant, packaging sealant, mining sealant uye mamwe marudzi.
2. Zvinoenderana nechikamu mushure mekuvaka, inogona kukamurwa kuita yakaporeswa sealant uye semi-yakarapwa sealant.Yakarapwa sealants inogona kukamurwa kuita rigid sealants uye inoshanduka sealants.Rigid sealant yakasimba inoumba mushure mevulcanization kana kusimba.Iine elasticity shoma, haigoni kukotama, uye kazhinji chibatanidza hachigoni kufamba;flexible sealant ndeye elastic uye yakapfava mushure mekuputika.Isina-kuporesa sealant inyoro-inorapa sealant inochengeta iyo isiri-kuomesa tackifier uye inoramba ichienda kumusoro mushure mekushandisa.
Structural sealant
Iyo structural sealant ine simba rakawanda (compressive simba> 65MPa, simbi-ku-simbi yakanaka tensile bonding simba> 30MPa, shear simba> 18MPa), inogona kumira mitoro mikuru, inoshingirira kuchembera, kuneta, uye ngura, uye ine kuita kwakanaka mukati. hupenyu hwayo hunotarisirwa.Yakagadzika adhesive inokodzera kusungirirwa kwezvimiro zvikamu zvinogona kumirisana nemasimba akasimba.
1. Inonyanya kushandiswa kune zvigadziriso kana zvisiri zvemaitiro ekubatanidza michina pakati pegirazi keteni madziro simbi uye girazi.
2. Girazi rinogona kubatanidzwa zvakananga nechepamusoro pezvikamu zvesimbi kuti zvigadzire chikamu chimwe chete chegungano kuti chinosangana nezvinodiwa zvekugadzira zvakakwana zvakavanzwa furemu kana semi-yakavanzika furemu madziro emaketeni.
3. Kubatana kwemaitiro uye kuiswa chisimbiso chegirazi rekudzivirira.
4. Inokodzera kusungirirwa, kuvhara uye kuvhara kwebwe rinoputika, girazi rakasvibiswa, girazi rinodzivirira, girazi regirazi, girazi rakavharidzirwa, zinc, mhangura, iron nezvimwe zvinhu.
