Kunezinhlobo ezahlukene zeminyango kanye nemichilo yamafasitela sealant.Imichilo ejwayelekile yomnyango kanye nefasitela ihlanganisa okulandelayo:
1. Umugqa wokuvala we-EPDM: I-EPDM (i-ethylene propylene diene monomer) i-sealing strip inokumelana nesimo sezulu esihle kakhulu nokumelana nokuguga, futhi ingasetshenziswa ngaphansi kwezimo zezulu ezihlukene.Inokunwebeka okuhle nokuthambile, futhi isetshenziswa kabanzi ekuvaleni nasekuvimbeleni amanzi eminyango namafasitela.
2. Umugqa wokuvala we-PVC: I-PVC (i-polyvinyl chloride) yokuvala i-PVC inokumelana nokugqwala kwamakhemikhali okuhle kakhulu kanye nokumelana nesimo sezulu, futhi ifanele ukuvalwa kweminyango namafasitela, ukuvala amanzi nokuvala umsindo.
3. I-Silicone sealing strip: I-Silicone sealing strip inezici zokumelana nezinga lokushisa eliphezulu, ukumelana nezinga lokushisa eliphansi kanye nokumelana nesimo sezulu, futhi ifanele ukuvala iminyango namafasitela adinga i-anti-oxidation kanye nokumelana nokushisa okuphezulu.
4. I-polyurethane sealing strip: I-polyurethane sealing strip inamandla amakhulu nokumelana nokugqoka, inganikeza umphumela omuhle wokuvala kanye nokumelana nomthelela, futhi ifanele ukuvala umnyango nefasitela kanye nokumelana nokucindezela komoya.
5. Imichilo yokuvalwa kwerabha: Izinto ezisetshenziswa kakhulu emicucu yokuvala iraba zihlanganisa irabha ye-nitrile (NBR), irabha ye-acrylic (ACM), i-neoprene (CR), njll., enokuqina okuhle kanye nokumelana nesimo sezulu, futhi ifanele ukuvalwa nokubekwa uphawu. yezicabha namafasitela.ubufakazi bamanzi.
6. Umugqa werabha yesipontshi: Umugqa wenjoloba wesipontshi unokunwebeka okuhle nokuthambile, unganikeza umphumela wokuvala ongcono kanye nomphumela wokuvala umsindo, futhi ulungele ukuvala nokumuncwa ukushaqeka kweminyango namafasitela.
Lezi zinhlobo zemicu yokuvala zinezici ezihlukene kanye nobubanzi bokusebenza, futhi ukukhethwa komugqa wokuvala ofanelekile kufanele kunqunywe ngokuya ngendawo ethile yohlelo lokusebenza, izidingo kanye nesabelomali.Kunconywa ukubhekisela kumingcele yezobuchwepheshe kanye neziphakamiso ezinikezwe umenzi lapho ukhetha ukuqinisekisa ukukhethwa kwemigqa efanelekile yomnyango kanye nefasitela.
