Baya ga ruwa, galibin kafofin watsa labarai da ake amfani da su wajen musayar zafi na farantin su ne ƙwaƙƙwaran bayani, ɗimbin bayani, sodium hydroxide, sulfuric acid da sauran kafofin watsa labarai na sinadarai, waɗanda ke da sauƙin haifar da lalata faranti da kumburi da tsufa na gasket.
Farantin karfe da gasket sune ainihin abubuwan da ke canza zafin farantin, don haka zaɓin farantin karfe da kayan gasket yana da mahimmanci musamman.
Zaɓin kayan aikin farantin wuta na farantin zafi:
| Ruwan da aka tsarkake, ruwan kogi, mai, man ma'adinai da sauran kafafen yada labarai | bakin karfe (AISI 304, AISI 316, da dai sauransu). |
| ruwan teku, brine, salinization da sauran kafofin watsa labarai | titanium da titanium palladium (Ti, Ti-Pd) |
| Tsarma sulfuric acid, tsarma sulfur gishiri ruwa bayani, inorganic ruwa bayani da sauran kafofin watsa labarai. | 20Cr, 18Ni, 6Mo (254SMO) da sauran gami |
| Babban zafin jiki da babban taro caustic soda matsakaici | Ni |
| Matsakaicin sulfuric acid, hydrochloric acid da phosphoric acid matsakaici | Hastelloy gami (C276, d205, B20) |
Zaɓin kayan abu na gasket don musayar zafi na farantin:
Yawancin mutane sun san cewa gaskets na roba ana amfani da su akai-akai, irin su EPDM, roba na nitrile, robar nitrile hydrogenated, fluororubber da sauransu.
| EPDM | Zazzabi na sabis shine -25 ~ 180 ℃. Ya dace da ruwa mai matsakaicin zafi mai zafi, tururi, ozone na yanayi, mai ba da man fetur ba, mai rauni acid, tushe mai rauni, ketone, barasa, ester, da sauransu. |
| NBR | Zazzabi na sabis shine - 15 ~ 130 ℃. Ya dace da nau'ikan mai na ma'adinai daban-daban kamar matsakaicin ruwa, mai mai haske, mai mai mai, man dabba da kayan lambu, ruwan zafi, ruwan gishiri, da sauransu. |
