Mashizha erabha akakosha kune ese maindasitiri, nekushandisa kwawo kunotsanangurwa nepakati pezvinyorwa zvinyorwa. Kubva parabha yechisikigo kusvika kune epamberi synthetics uye yakadzokororwa akasiyana, imwe neimwe mhando inopa yakasarudzika mashandiro akagadzirirwa kune chaiwo ekushandisa kesi, zvichiita kuti kusarudzwa kwezvinhu kuve kwakakosha pakushanda nesimba uye kusimba. Pazasi pane kutsanangurwa kwakadzama kwezvakajairwa rubber sheet zvinhu, zvimiro zvavo, maapplication, uye yakakosha kuenzanisa kwekuita.
Key Rubber Sheet Materials: Properties & Applications
1. Natural Rubber (NR) Sheets
Yakatorwa kubva kulatex yemiti yerabha, mapepa eNR anokosheswa nekusarudzika elasticity (kurebesa kusvika ku800%), kusimba kwakanyanya, uye kusimba kwepamusoro. Vanoita zvakanaka mukupisa kuri pakati nepakati (-50°C kusvika 80°C) asi vari panjodzi yemafuta, ozone, nemwaranzi yeUV.
- Zvishandiso: General kugadzira gaskets, mabhandi ekutakura, zvisimbiso zvemugonhi wemotokari, zvinobatisa zvekuvhundutsa, uye zvinhu zvevatengi (semuenzaniso, matinji erabha).
2. Nitrile (NBR) Sheets
Rabha rekugadzira rakagadzirwa kubva kubutadiene uye acrylonitrile, mashiti eNBR anokunda mumafuta, mafuta, uye makemikari kuramba. Vanopa simba rakanaka uye vanoita mukupisa kubva -40 ° C kusvika 120 ° C, kunyange zvazvo elasticity yakaderera pane NR.
- Zvishandiso: Mapombi eoiri negasi, ejini injini gaskets, hosi dzemafuta, matangi emaindasitiri, uye michina yekugadzira chikafu (chikafu-giredhi NBR).
3. Silicone (SI) Sheets
Anozivikanwa nekunyanyisa kupisa tembiricha (-60 ° C kusvika 230 ° C, aine mamwe mamakisi anosvika 300 ° C), mashiti esilicone haana chepfu, anochinjika, uye anoshingirira kune ozone, UV, uye kuchembera. Ivo vane mwero kusimba simba uye kushoma mafuta kuramba.
- Zvishandiso: Zvishandiso zvemuchadenga, kuvharwa kwemagetsi, michina yekugadzira chikafu, michina yekurapa (inogoneka), uye yakanyanya-tembiricha gaskets.
4. EPDM (Ethylene Propylene Diene Monomer) Sheets
Rabha rekugadzira rine mamiriro ekunze akanaka, UV, uye ozone kuramba, mapepa eEPDM anoita mu -40°C kusvika 150°C uye anoshingirira zvikuru kumvura, chiutsi, uye makemikari akapfava. Ivo vane yakaderera mafuta kuramba asi yakanakisa durability.
- Zvishandiso: Kuvaka kudzivirira mvura (matenga, dzimba dzepasi), kuvharirwa kwekunze, zvisimbiso zvemahwindo emotokari, mabhanhire ekushambira, uye masisitimu eHVAC.
5. Neoprene (CR) Sheets
Yakagadzirwa kubva ku chloroprene, neoprene mashizha anopa musanganiswa wakaenzana wekupfeka kuramba, kushanduka, uye kunonoka kwemurazvo. Dzinoita mu -30°C kusvika 120°C uye dzinoshingirira kuozone, UV, uye makemikari akapfava, ane mwero mafuta kuramba.
- Zvishandiso: Maindasitiri hose, giya rekudzivirira (magirovhosi, waders), zvisimbiso zvemugungwa, anti-slip flooring, uye yemagetsi chikamu chekudzivirira.
6. Recycled Rubber Sheets
Yakagadzirwa kubva kune-post-consumer (semuenzaniso, matayi) kana post-industrial rubber tsvina, aya mapepa ane eco-friendly, anodhura-inoshanda, uye anopa kunaka kupfeka kuramba. Vane yakaderera elasticity uye tembiricha kushivirira (-20 ° C kusvika 80 ° C) kupfuura mhandara zvinhu.
- Zvishandiso: Nzvimbo dzekutamba, matinji emitambo, mabhampa ekupaka, kuvharidzira ruzha, uye meti-chinangwa-chakawanda.
Kuita & Basa Kuenzanisa
Performance Metric NR NBR SI EPDM CR Recycled
Nekushanda, chinyorwa chega chega chinogadzirisa zvinodiwa neindasitiri zvakasiyana: NR neCR inotungamira kuchinjika kune zvine simba zvikumbiro (semuenzaniso, kubatwa nekutya); NBR inotarisana nemakemikari/oiri kuramba kune zvigadziriso zveindasitiri; SI uye EPDM inopfuura munzvimbo dzakanyanyisa (yakakwirira tembiricha / mamiriro ekunze); uye recycled rabha zvikero mutengo uye kusimba kune zvisiri zvakakosha kushandiswa.
Kunzwisisa misiyano iyi kunovimbisa kuti mabhizinesi anosarudza iyo chaiyo rabha pepa zvinhu kuti ikwidze mashandiro, kuderedza mari yekugadzirisa, uye kusangana nemaindasitiri zviyero. Sezvo tekinoroji iri kufambira mberi, vagadziri vanoramba vachinatsiridza zvivakwa-zvakadai sekuvandudza EPDM's kuramba mafuta kana kuwedzera elasticity yerabha yakadzokororwa-kuwedzera kuchinjika kwemapepa erabha mumaindasitiri epasi rose.
