● Kuramba kwemamiriro ekunze: Ichi chisimbiso chinopikisa zvakanyanya kumamiriro ekunze, UV mwaranzi, uye ozone, zvichiita kuti ive yakakodzera kushandiswa kunze kwekushandisa.
● Kudzivirirwa kwekushisa: Silicone Structural Sealant inogona kumira kutonhora kubva -50 ° C kusvika 150 ° C (-58 ° F kusvika 302 ° F), zvichiita kuti ive yakakodzera kushandiswa mukupisa kwepamusoro-soro.
● Kureruka kwekushandisa: Ichi chisimbiso chiri nyore kushandisa uye chinogona kushandiswa kusvika pakupedza.
● Inoyevedza: Inowanikwa mumarudzi akasiyana-siyana, kusanganisira akajeka, machena, matema, uye grey, kuti aenderane ne substrates dzakasiyana uye zvinodiwa zvekunaka.
DOWSIL ™ SJ268 Silicone Structural Sealant yakaedzwa uye yakasimbiswa kuti ienderane neyakasiyana indasitiri zviyero nemirau.Mimwe yemazinga akatorwa nechisimbiso ichi anosanganisira:
1. ASTM C1184 - Yakajairwa Kurongeka kweStructural Silicone Sealants: Iyi chiyero inotsanangura zvinodikanwa zvechimwe-chikamu structural silicone sealants inoshandiswa mukuvaka nekuvaka.
2. ASTM C920 - Yakajairwa Kutsanangurwa kweElastomeric Joint Sealants: Iyi chiyero inovhara zvinodiwa zvechimwe-chikamu uye maviri-chikamu elastomeric sealants anoshandiswa mukuvaka nekuvaka.
3. ISO 11600 - Kuvaka Kuvaka - Kubatanidza zvigadzirwa: Zvikamu uye zvinodikanwa zvezvisimbiso: Iyi chiyero inotsanangudza kupatsanurwa uye zvinodiwa zvemajoini sealants anoshandiswa mukuvaka zvivakwa.
4. UL 94 - Yakajairwa Miedzo yeKupisa kwePlastiki Zvishandiso zveZvikamu muZvishandiso uye Zvishandiso: Iyi chiyero inovhara kuyedzwa kwekupisa kwemidziyo yepurasitiki inoshandiswa mumidziyo nemidziyo.
5. AAMA 802.3 - Voluntary Specification yeChemical Resistant Sealants: Iyi tsanangudzo inovhara zvinodiwa zvemakemikari-resistant sealants anoshandiswa mukuvaka nekuvaka.
Heano maitiro akajairwa ekushandisa sealant:
1. Gadzirira pamusoro: Pamusoro pacho panofanira kunge pakachena, pakaoma, uye pasina zvinosvibisa, zvakadai semafuta, huruva, kana marara.Shandisa yakakodzera yekuchenesa solvent kubvisa chero tsvina kana zvakasara.
2. Isai backer rod: Isa yakakodzera backer tsvimbo kusvika pakadzika nehupamhi hwejoini.Izvi zvinobatsira kuve nechokwadi cheiyo sealant kudzika uye kupa chisimbiso chiri nani.
3. Cheka muromo: Cheka muromo we cartridge ye sealant kusvika kuhukuru hunodiwa pane 45-degree angle.
4. Isa chisimbiso: Isa chisimbiso kune chibatanidzwa mubheji inopfuurira uye yakafanana.Shandisa iyo sealant nechishandiso chakakodzera kuti ive nechokwadi chekutsetseka uye kunyange kupera.
5. Bvumira chisimbiso kuti chirape: DOWSIL™ SJ268 Silicone Structural Sealant inorapa pakupisa kwekamuri nekuita nehunyoro mumhepo.Nguva yekurapa inosiyana zvichienderana nekupisa, hunyoro, uye saizi yemajoini, asi kazhinji inotangira pamazuva manomwe kusvika gumi nemana.
6. Chenesa: Chenesa chero chisimbiso chero chipi zvacho chisati chapora, uchishandisa mushonga wekuchenesa wakakodzera.
Heano mamwe anokurudzirwa mameseji egungano echisimbiso ichi:
1. Sealant inofanira kuiswa panzvimbo dzakachena, dzakaoma, uye dzine ruzha.Nzvimbo idzi dzinofanirwa kunge dzisina zvinosvibisa, zvakaita semafuta, guruva, kana marara.
2. Iyo yakakurudzirwa yakabatana dhizaini inofanirwa kuteverwa kuti ive nechokwadi cheiyo sealant kudzika uye kupa yakakwana kugona kufamba.
3. Kubatana kunofanira kugadzirirwa kubvumira zvishoma zve 25% kufamba mu sealant.
4. Tembiricha ye ambient panguva yekushandiswa inofanira kuva pakati pe5°C kusvika 40°C (41°F kusvika 104°F) kuitira migumisiro yakanaka.
5. Hunyoro hwehukama panguva yekushandiswa hunofanira kunge huri pasi pe80% kudzivirira unyoro kubva pakukanganisa nzira yekurapa.
