Mapepala a rabara ndi ofunika kwambiri m'mafakitale onse, ndipo zofunikira zake zimatanthauzidwa ndi zolemba zapakati. Kuchokera ku mphira wachilengedwe kupita kuzinthu zotsogola komanso zosinthidwanso, mtundu uliwonse umapereka mawonekedwe apadera ogwirizana ndi momwe amagwiritsidwira ntchito, kupangitsa kusankha kwazinthu kukhala kofunikira kuti mugwire bwino ntchito komanso kulimba. Pansipa pali tsatanetsatane wa zida zofananira za rabara, mawonekedwe ake, ntchito, ndi kufananitsa kwakukulu kwa magwiridwe antchito.
Zida Zofunikira za Rubber: Katundu & Ntchito
1. Natural Rubber (NR) Mapepala
Zochokera ku latex yamitengo ya rabara, mapepala a NR ndi amtengo wapatali chifukwa cha kusungunuka kwapadera (kutalika mpaka 800%), kulimba kwamphamvu kwambiri, ndi kupirira kwapamwamba. Zimagwira ntchito bwino potentha (-50 ° C mpaka 80 ° C) koma zimatha kutenthedwa ndi mafuta, ozoni, ndi kuwala kwa UV.
- Ntchito: Ma gaskets opangira zonse, malamba otumizira, zisindikizo zapakhomo zamagalimoto, zotsekera, ndi katundu wogula (mwachitsanzo, mphasa za rabara).
2. Mapepala a Nitrile (NBR).
Labala yopangidwa kuchokera ku butadiene ndi acrylonitrile, mapepala a NBR amapambana mumafuta, mafuta, ndi kukana mankhwala. Amapereka mphamvu zabwino zamakokedwe ndipo amachita kutentha kwapakati pa -40 ° C mpaka 120 ° C, ngakhale kuti kutsekemera kumakhala kochepa kuposa NR.
- Ntchito: Mapaipi amafuta ndi gasi, ma gaskets a injini zamagalimoto, mapaipi amafuta, matanki akumafakitale, ndi zida zopangira chakudya (NBR ya chakudya).
3. Mapepala a Silicone (SI).
Amadziwika ndi kukana kutentha kwambiri (-60 ° C mpaka 230 ° C, ndi magiredi mpaka 300 ° C), mapepala a silikoni sakhala oopsa, osinthika, komanso osamva ozone, UV, ndi ukalamba. Amakhala ndi mphamvu zolimbitsa thupi komanso amakana mafuta.
- Ntchito: Zida zam'mlengalenga, zotchingira zamagetsi, makina opangira chakudya, zida zamankhwala (zosabala), ndi ma gaskets otentha kwambiri.
4. EPDM (Ethylene Propylene Diene Monomer) Mapepala
Rabara yopangidwa ndi nyengo yabwino, UV, ndi ozoni kukana, mapepala a EPDM amachita mu -40 ° C mpaka 150 ° C ndipo sagonjetsedwa kwambiri ndi madzi, nthunzi, ndi mankhwala ochepa. Iwo ali otsika kukana mafuta koma kwambiri durability.
- Ntchito: Zomangamanga zotsekera madzi (madenga, zipinda zapansi), zotsekera panja, zosindikizira zamawindo agalimoto, zomangira zamadzi osambira, ndi makina a HVAC.
5. Mapepala a Neoprene (CR).
Opangidwa kuchokera ku chloroprene, mapepala a neoprene amapereka kusakaniza koyenera kwa kukana kuvala, kusinthasintha, ndi kuchedwa kwamoto. Amagwira ntchito mu -30 ° C mpaka 120 ° C ndipo sagonjetsedwa ndi ozone, UV, ndi mankhwala ofatsa, ndi kukana mafuta pang'ono.
- Ntchito: Mapaipi a mafakitale, zida zodzitetezera (magulovu, ma waders), zisindikizo zam'madzi, zotchingira pansi, ndi chitetezo chamagetsi.
6. Zobwezerezedwanso Rubber Mapepala
Opangidwa kuchokera kwa ogula pambuyo (mwachitsanzo, matayala) kapena zinyalala za raba zomwe zachitika pambuyo pa mafakitale, mapepalawa ndi okonda zachilengedwe, otsika mtengo, ndipo amapereka kukana kwabwino kwa kuvala. Amakhala ndi kutsika kotsika komanso kulekerera kutentha (-20 ° C mpaka 80 ° C) kuposa zida za namwali.
- Ntchito: Malo ochitira masewera, masewera othamanga, mabampa oimikapo magalimoto, zotchingira mawu, ndi mphasa zogwiritsiridwa ntchito wamba.
Kufananiza kwa Magwiridwe & Ntchito
Performance Metric NR NBR SI EPDM CR Yobwezerezedwanso
Kugwira ntchito, chilichonse chimayang'ana zofunikira zamakampani: NR ndi CR zimayika patsogolo kusinthasintha kwa magwiridwe antchito (mwachitsanzo, kuyamwa modzidzimutsa); NBR imayang'ana kwambiri kukana kwa mankhwala / mafuta pazosintha zamakampani; SI ndi EPDM zimapambana m'malo ovuta kwambiri (kutentha kwambiri / nyengo); ndi zobwezerezedwanso mphira sikelo ndi kukhazikika kwa ntchito zosafunikira.
Kumvetsetsa kusiyana kumeneku kumatsimikizira kuti mabizinesi amasankha pepala loyenera labala kuti akwaniritse bwino ntchito, kuchepetsa mtengo wokonza, ndikukwaniritsa miyezo yamakampani. Pamene ukadaulo ukupita patsogolo, opanga akupitilizabe kukulitsa zinthu zakuthupi - monga kuwongolera kukana kwamafuta a EPDM kapena kukulitsa kulimba kwa rabara wogwiritsiridwa ntchito - kukulitsa kusinthasintha kwa mapepala a rabala padziko lonse lapansi.
