Rabha yechisikigo inogona kutsungirira zvinhu zvinosanganisira mvura yakachena, mvura yemunyu, mhepo, gasi risina simba, alkalis, uye munyu; zvisinei, mafuta emineral uye zvinonyungudutsa zvisiri polar zvinoikuvadza. Inoshanda zvakanaka kwazvo patembiricha yakaderera uye ine tembiricha yekushandiswa kwenguva refu isingapfuuri 90°C. Inoshanda pa -60°C. Shandisa muenzaniso uri pamusoro.
Mafuta anosanganisira mafuta emafuta, mafuta ekuzora, uye mafuta epeturu zvinogamuchirwa kuti zvishandiswe nerabha ye nitrile. Tembiricha inoshandiswa kwenguva refu ndeye 120°C, 150°C mumafuta anopisa, uye -10°C kusvika -20°C patembiricha yakaderera.
Mvura yegungwa, maasidhi asina simba, maalkali asina simba, mhinduro dzemunyu, kudzivirira kukwegura kweokisijeni neozone zvakanaka, kudzivirira mafuta kusina kunaka pane nitrile rabha asi kuri nani pane mamwe marabha akajairika, kupisa kwenguva refu kuri pasi pe90 °C, kupisa kwakanyanya kushandiswa kusingapfuure 130 °C, uye kupisa kwakaderera kuri pakati pe -30 ne50 °C zvese zvakakodzera chloroprene rabha.
Rabha yefluorine inouyamumhando dzakasiyana-siyana, dzose dzine simba rakanaka rekudzivirira acid, oxidation, oiri, uye solvent. Tembiricha yekushandiswa kwenguva refu yakaderera pane 200°C, uye inogona kushandiswa neanenge ese ma acid media pamwe nemamwe mafuta uye solvents.
Rabha rinoshandiswa zvakanyanya se flange gasket yemapaipi kana manhole emvura anowanzo pwanywa uye maburi emaoko, uye kumanikidzwa hakupfuuri 1.568MPa. Magasket erabha ndiwo akapfava uye akanakisa pakubatanidza pakati pemarudzi ese emagasket, uye anogona kugadzira sealing effect nechisimba chidiki chekusimbisa. Nekuda kweukobvu hwayo kana kuoma kwayo, gasket inosvinwa nyore nyore kana iri pasi pekumanikidzwa kwemukati.
Mapepa erabha anoshandiswa muzvinhu zvinonyungudutsa zvakaita sebenzene, ketone, ether, nezvimwewo zvinogona kukonzera kutadza kushanda kweseal nekuda kwekuzvimba, kukura kwehuremu, kupfava, uye kunamira. Kazhinji, hazvigone kushandiswa kana huwandu hwekuzvimba hwacho huri pamusoro pe30%.
Mapedhi erabha anonyanya kushandiswa kana paine vacuum uye pressure yakaderera (kunyanya pasi pe0.6MPa). Chinhu cherabha chakawanda uye mweya unopindika zvishoma. Kune vacuum containers, semuenzaniso, fluorine rabber inoshanda zvakanyanya se sealing gasket sezvo vacuum level inogona kusvika pa1.310-7Pa. Rabber pad inofanira kubikwa uye kupombwa isati yashandiswa munzvimbo ye vacuum iri pakati pe10-1 kusvika 10-7Pa.
Kunyangwe rabha nezvimwe zvinhu zvakasiyana-siyana zvakaiswa mugasket, dambudziko guru nderekuti haigone kuvhara maburi madiki aripo, uye kune mukana wekupinda mukati kunyangwe mutengo wacho uri mudiki pane mamwe magasket uye zviri nyore kushandisa. Saka, kunyangwe kumanikidzwa nekupisa zvisina kunyanyisa, hazvigone kushandiswa muzvinhu zvine tsvina yakawanda. Nekuda kwekushandiswa kwerabha nezvinoita kuti zviome kana zvikashandiswa mune imwe nzvimbo ine mafuta anodziya zvakanyanya, kazhinji panosvika pakupera kwekushandiswa, simba rinodzikira, zvinhu zvinosununguka, uye kupinda mukati megasket, zvichikonzera kubhoikana nekuputa. Pamusoro pezvo, pakupisa kwakanyanya, rabha reasbestos rinonamira nyore nyore pamusoro peflange sealing, izvo zvinoita kuti kutsiva gasket kuve kwakaoma.
Simba rekuchengetedza gasket rinoona kumanikidzwa kwegasket munzvimbo dzakasiyana-siyana kana ichipisa. Zvinhu zvine asbestos fibers zvine mvura yekristaro nemvura yeadsorption. Pamusoro pe500°C, mvura yekristaro inotanga kunaya, uye simba rayo rakaderera. Pa110°C, zvikamu zviviri muzvitatu zvemvura yakanyungudika pakati pemafibers zvakanyungudika, uye simba refiber rekunyungudika raderera neinenge 10%. Pa368°C, mvura yese yakanyungudika yanyungudika, uye simba refiber rekunyungudika raderera neinenge 20%.
Simba repepa rerabha reasbestos rinonyanya kukanganiswa nechinhu chiri mukati. Semuenzaniso, simba rekudhonza repepa rerabha reasbestos rinodzivirira mafuta reNo. 400 rinosiyana pakati pemafuta ekuzora endege nemafuta endege ne80%, izvo zvinokonzerwa nekuti kuzvimba kwerabha mupepa repeturu yendege kwakanyanya kupfuura mafuta ekuzora endege. Tichifunga nezvezvataurwa pamusoro apa, tembiricha yekushanda yakachengeteka uye huwandu hwekumanikidzwa kwepepa rerabha reasbestos repamba XB450 iri pakati pe250 °C kusvika 300 °C uye 3 3.5 MPa; tembiricha yepamusoro yepepa rerabha reasbestos rinodzivirira mafuta reNo. 400 i350 °C.
Maion echloride nesarufa aripo mupepa rerubha reasbestos. Maflange esimbi anogona kugadzira bhatiri rinoita ngura nekukurumidza mushure mekunwa mvura. Kunyanya, pepa rerubha reasbestos risingapindi mafuta rine huwandu hwesarufa hwakakwira kakawanda kupfuura pepa rerubha reasbestos renguva dzose, zvichiita kuti risakodzere kushandiswa muzvinhu zvisina mafuta. Mumafuta nezvinonyungudutsa, gasket rinozvimba, asi kusvika padanho, harina simba pakukwanisa kuvhara. Semuenzaniso, bvunzo yekunyudzwa kwemaawa makumi maviri nemana mumafuta endege patembiricha yemumba inoitwa papepa rerubha reasbestos risingapindi mafuta reNo. 400, uye zvinorayirwa kuti kuwedzera kwehuremu kunokonzerwa nekunyudzwa kwemafuta hakufanirwe kupfuura 15%.
