1. Chii chinonzi silicone sealant?
Silicone sealant paste yakagadzirwa nepolydimethylsiloxane sechinhu chikuru mbishi, inowedzerwa ne crosslinking agent, filler, plasticizer, coupling agent, uye catalyst in vacuum state. Inopfuura nepanzvimbo yekupisa. Inopindirana nemvura mumhepo uye yoomesa kuita elastic silicone rabha.
2. Musiyano mukuru pakati pesilicone sealant uye mamwe organic sealants?
Iine kunamatira kwakasimba, kusimba kwesimba, kusamira kwemamiriro ekunze, kudzungudza kuramba, kunyorova, kuramba kunhuwa, uye kuchinjika kune shanduko huru mukutonhora nekupisa. Yakabatana nekushanda kwayo kwakafara, inogona kuona kunamatira pakati pezvizhinji zvekuvaka, inova yakasarudzika yakajairika hunhu hwesilicone sealant iyo yakasiyana kubva kune zvimwe zvakajairika organic adhesive zvinhu. Izvi zvinokonzerwa neyakasiyana kemikari molecular chimiro chesilicone sealant. Iyo ketani huru yeSi-O bond haina kukuvadzwa nyore nemirairo ye ultraviolet. Panguva imwecheteyo, tembiricha yegirazi yesilicone rabha yakadzikira kupfuura yeyakajairwa organic zvinhu. Inogona kuramba iine elasticity yakanaka pasi pekushisa kwakadzika (-50 ° C) pasina embrittlement kana kuputika, uye haisi nyore kupfava uye kuderera pasi pemamiriro ekushisa kwepamusoro (200 ° C). Inogona kuchengetedza kushanda kwakagadzikana muhupamhi hwekushisa. Silicone sealant zvakare haina kuyerera nekuda kwehuremu hwayo, saka inogona kushandiswa mumajoini epamusoro kana madziro emadziro pasina sag, kudonha kana kutiza. Aya epamusoro zvimiro zvesilicone sealants chikonzero chakakosha chekushandiswa kwayo kwakakura mumunda wekuvaka, uye ichi chivakwa zvakare mukana wayo pane mamwe organic sealants.
