Rabha chisimbiso mitsetse Zvakasiyana-siyana muzvinhu, maitiro uye maumbirwo, uye mhando dzakasiyana dzezvigadzirwa dzine musiyano uri pachena mukushanda uye mamiriro akakodzera. Kupatsanura kwesainzi uye kufananidza mamiriro ezvinhu kwakarurama kunogona kuvandudza zvinobudirira kushanda kweseal uye hupenyu hwebasa rezvigadzirwa, uye kuderedza mari yekugadzirisa mainjiniya nemidziyo. Parizvino, mitsetse mikuru yeseal yerabha mumusika yakakamurwa kuita zvikamu zvina zvikuru: rabha yeEPDM, rabha yePVC, rabha yesilicone uye rabha yechiponji, imwe neimwe ine zvakanakira kushanda kwayo uye minda yekushandiswa yakagadzika, ichigadzira sisitimu yakazara yeseal inofukidza mamiriro ekugadzira ehurumende, ezvivakwa, emaindasitiri uye epamusoro-soro.
EPDM rabha yekuvhara mitsetse Zvakaiswa sezvigadzirwa zveinjiniya yekunze neyekuvaka, zvine simba rekudzivirira mamiriro ekunze uye kukwegura, zvakakodzera kuvaka madziro ekunze, magonhi nemahwindo, madziro emaketeni, midziyo yekunze uye kuvhara kunze kwemotokari. Ndiyo sarudzo yekutanga yekuchengetedza simba uye kuchengetedza nguva refu kwezvivakwa zvehurumende nezvemabhizinesi. Zvishandiso zvePVC zvekuvhara rabha zvakaiswa sezvigadzirwa zvemukati zvevashandi, zvine mashandiro anodhura uye masitayera akapfuma, zvakakodzera magonhi emukati, mahwindo, fenicha, makabati nemidziyo yemagetsi yemumba, zvichizadzisa zvinodiwa zvezuva nezuva zvekuvhara mukati. Zvishandiso zveSilicone rabha zvekuvhara zvigadzirwa zvepamusoro-soro, zvakakodzera mamiriro ekupisa kwakanyanya, ehutsanana uye akarurama akadai semichina yekudya, midziyo yekurapa, maovheni nemidziyo yemagetsi yepamusoro-soro.
Rabha yechipanjizvisungo zvekuvharaTarisa pakudzivirira ruzha rwebuffer uye kuvharwa kwemaburi zvisina kurongeka, zvakakodzera mamiriro ezvinhu anoda kunyudzwa kweshock, kuderedza ruzha uye kupfava, kusanganisira kuderedza ruzha rwemusuwo nepamahwindo, kuvharwa kwemidziyo yemakanika, kuvharwa kwemaburi mukati memotokari uye kuvharwa kwebhokisi. Panyaya yekupatsanurwa kwechimiro, mitsetse yekuvhara rabha yakakamurwa kuita mhando yakasimba, mhando isina chinhu, mhando ine maburi akawanda uye mhando yakaumbwa zvakasiyana. Mhando yakasimba ine kuramba kwakasimba kwekupfeka uye kuramba kumanikidzwa; mhando isina chinhu ine kusimba kuri nani uye kudzivirira ruzha; mhando ine maburi akawanda inoita kuti kuvharwa kwemaburi akawanda kuve kwakawanda uye inovandudza kushanda kwekudzivirira mvura nemhepo; zvigadzirwa zvine chimiro chakakosha zvakagadzirirwa michina yakakosha uye saizi chaiyo ye maburi.
Mukusarudza mainjiniya anoshanda, kushongedzwa kwemukati kunonyanya kukosha kune PVC nemachira erabha esponji asingadhuri, nepo mapurojekiti ekuvaka ekunze achisarudza zvidimbu zveEPDM zvisingapindi mamiriro ekunze. Mamiriro ekupisa kwakanyanya, ehutsanana uye akarurama emaindasitiri anoshandisa chete zvidimbu zverabha zvesilicone zvemhando yepamusoro uye zvekurapa. Kufananidza kwakanyatsojeka pakati pemhando dzezvigadzirwa nemamiriro ekushandiswa kunowedzera kushanda kwezvinhu, kudzivirira kutadza kwechisimbiso nguva isati yakwana uye kunoderedza mari yekugadzirisa michina neinjiniya. Nekuvandudzwa kwakagadziridzwa kweindasitiri yekusimbisa, zvidimbu zverabha zvemhando yepamusoro zvave zvakakurumbira, zvichipa mhinduro dzehunyanzvi dzekusimbisa minda yakasiyana-siyana yeindasitiri neyakavakwa.
