PVC sealing strips yave favourite yemapurasitiki esimbi gonhi nemahwindo ekuisa chisimbiso mitsetse nekuti haina kutsemuka uye iri nyore kubatanidza. Asi makore 2-3 chete, dambudziko rakaonekwa. Kuparadzaniswa kwePVC plasticizers, dambudziko rakaoma reindasitiri yepasi rose, rave richiratidzwa zvakajeka muPVC sealing strips.
Pamusana pekuparadzaniswa kweplasticizer, purogiramu yakasvibiswa nemucheka werubha, kureba kunopfupiswa, chikamu chakaputsika chinopfupiswa, uye matambudziko ekuvhara chisimbiso akawandisa. Nekudaro, maChinese-style diki workshop processing, Chinese-style kudzikisa mutengo, uye Chinese-style yakaderera-mutengo kukwikwidza nemasuo uye hwindo sealing strip vanogadzira zvakakonzera kushandiswa kwemapurasitiki akaremara uye akadzokorodza PVC, izvo zvakawedzera matambudziko eiyo yese sealing strip indasitiri. Kupera kwePVC sealing strip kuri kutanga kuoneka.
EPDM EPDM sealing strips Mukutanga kwe2000, nyika yakapa mutemo wehurumende kurambidza kushandiswa kwe polyvinyl chloride PVC sealing strips, uye yakakurudzira kushandiswa kweEPDM EPDM sealing strips uye MVQ silicone rubber sealing strips. EPDM sealing strip, yekumusoro-giredhi yekuisa chisimbiso tambo inoshandiswa mumotokari nezvitima, yakazogamuchirwa neindasitiri yekuvaka.
Muchokwadi, yakashandiswa zvakanyanya muindasitiri yemasuo nehwindo mushure megore ra2002. Panguva iyoyo, magonhi nemahwindo zvishoma nezvishoma zvakapinda munguva yekuputsika bhiriji aluminium alloys. EPDM yakave yakafanana neyepamusoro-giredhi yekuisa chisimbiso mitsetse nekuda kwehukuru hwemuviri zvimiro uye yakanaka kuramba kuchembera. Muna 2011, yakakanganiswa nemafuta epasi rose nezvimwe zvinhu, mutengo we ethylene propylene wakakwira, uye nguva yechando yeEPDM yekuisa chisimbiso mitsetse yakauya, saka huchenjeri hweChinese hwakauya, rabha yakadzoserwa yakatanga kushandiswa muhuwandu hwakawanda, uye misika yese yekuisa chisimbiso yaive mumhirizhonga. Zvisimbiso zvakanaka zvakaoma kuwana. Mugadziri wemitsetse yekuisa chisimbiso pagonhi nehwindo@门Window气气调板厂家Imwe dunhu muChina ndimo munobva machira ekuvharisa edzimba, uye zvikamu makumi manomwe kubva muzana zveChina zveEPDM zvekuvharisa zvisimbiso zvinobva mudunhu iri. Kune sahwira ari pabasa rimwe chete mudunhu rino, uye makumi manomwe muzana ematunhu ethylene-propylene sealing strips anobva kwatiri.
Silicone rubber sealing strip haisi iyo yazvino zvinhu zvekuisa chisimbiso mitsetse, asi handizvo. Silicone rabha ine nhoroondo yemakumi emakore muChina. Vagadziri vegonhi nehwindo sealing strip zvechokwadi ndivo vanofarirwa nerabha mumakore mashoma apfuura, uye vakatetepa. Mumakore achangopfuura, mari yacho yakaderera zvishoma nezvishoma, uye yakashandiswa zvishoma nezvishoma pakuvaka zvisimbiso.
Kuenzaniswa ne ethylene-propylene rabha, mukana wesilicone rubha yekuvharisa ndeyekuti ine zvirinani kuderera uye deformation kuita pane ethylene-propylene rabha, saka yekuisa chisimbiso iri nani, uye kubva musimboti wenguva-tembiricha kuenzana, silicone rabha inokwanisa kutsungirira tembiricha inosvika 300 ° C, uye isingaite epylenepropylene rubber. Rabha iri pa 180°C zvakanakisa. Pasi petembiricha imwe chete, hupenyu hwesilicone rabha hwakapetwa kaviri kupfuura ethylene propylene rubber, uye hupenyu hwesevhisi hurefu. Uye ine yakanakisa physiological inertia, isiri-chepfu, isinganakidze, silicone rabha inewo yakanakisa kupisa, kudzivirira kutonhora, dielectric zvimiro, ozone kuramba uye mumhepo kuchembera kuramba uye mamwe mabasa, basa rakatanhamara resilicone rabha kushandisa tembiricha yakafara, inogona Shandisa gonhi uye hwindo sealing strip mugadziri kwenguva yakareba pa -60 ° C (kana yakaderera 50 ° C tembiricha) kusvika (250 ° C). Saka silicone rabha isarudzo yakanaka yekuvaka zvisimbiso munguva yemazuva ano.
