Kodi payipi ya rabara ya EPDM ndi yotani?

EPDM rabara payipi, monga payipi yopangira mphira yochita bwino kwambiri, imakhala yosasinthika m'mafakitale ambiri ndi ubwino wake wapadera komanso malo ambiri ogwiritsira ntchito. Paipi iyi imagwiritsa ntchito mphira wa ethylene propylene diene monomer (EPDM) ngati zida zazikulu. Zimapangidwa mosamala kudzeraZebungKupanga kwaukadaulo kwaukadaulo, kotero kuti mankhwalawa ali ndi zinthu zabwino kwambiri zakuthupi ndi zamankhwala ndipo amatha kugwira ntchito mokhazikika m'malo osiyanasiyana ovuta.

1）. Kuchita bwino kwambiri

1. Kukana kutentha kwakukulu:EPDM rabara payipiimatha kupirira kutentha mpaka 150 ° C ndipo imatha kugwirabe ntchito mosasunthika m'malo otentha kwambiri. Izi zimapangitsa kuti zikhale zoyenera makamaka pazochitika zomwe zimafuna njira zotumizira zotentha kwambiri, monga mapaipi otenthetsera magalimoto, paipi yamadzi yozizirira m'mafakitale, ndi zina zotere. Kumalo otentha kwambiri,EPDM mphira mapaipiakhoza kusunga bata la thupi ndi mankhwala katundu.

2. Chemical resistance:EPDM mphira mapaipikukhala ndi kulolerana kwabwino kwa mankhwala ambiri, amatha kugwira ntchito mokhazikika m'malo osiyanasiyana ovuta, ndipo samawonongeka ndi media. Paipi iyi imatha kukana dzimbiri kuchokera kumitundu yosiyanasiyana ya asidi ndi alkali, mafiriji ndi zinthu zina, motero imagwiritsidwa ntchito kwambiri pamachitidwe otumizira zinthu m'mafakitale, chakudya, mankhwala ndi zina.

3. Kukana kukalamba:EPDM rabara payipiamasonyeza kukana kukalamba mwamphamvu pansi pa kuwala kwa dzuwa, mpweya ndi kutentha kwapamwamba, ndipo amatha kusunga bata ndi moyo wautumiki wa zinthuzo kwa nthawi yaitali. Kapangidwe kake ka mankhwala ndi kokhazikika, unyolo waukulu umapangidwa ndi ma hydrocarbon okhazikika odzaza ndi mankhwala, ndipo amakhala ndi zomangira ziwiri zopanda unsaturated mu unyolo wam'mbali, kotero sikophweka kukalamba, kuumitsa, kusweka ndi zochitika zina.

4. Kukana kwanyengo ndi kukana kuvala:EPDM rabara payipiali ndi mphamvu yolimbana ndi nyengo ndipo amatha kukana kukokoloka kwa malo ovuta monga kuwala kwa ultraviolet, mphepo ndi mvula, ayezi ndi matalala. Nthawi yomweyo, kukana kwake kwabwino kwambiri kumalimbana ndi kukangana ndi kuvala, kumateteza njira yopatsirana mkati mwa payipi, ndikutalikitsa moyo wautumiki.

5. Makina apamwamba kwambiri:EPDM rabara payipiili ndi mphamvu zolimba kwambiri, yopindika, kukhazikika komanso kukana kuvala, ndipo imatha kupirira kupsinjika kwakukulu komanso kupsinjika kwa static. Katundu wamakina wabwino kwambiri amalolaEPDM rabara payipikuti mukhalebe okhazikika pansi pa zovuta zosiyanasiyana.

2). Zambiri zofunsira

1. Makampani amagalimoto:EPDM rabara payipiali ndi malo ofunikira mumakampani agalimoto ndipo amagwiritsidwa ntchito kwambiri pamakina oyendetsa magalimoto, machitidwe ozizira, makina owongolera mpweya, machitidwe amafuta, ndi zina zambiri. Kukana kwake kutentha kwambiri komanso kukana kwa asidi ndi alkali kumathandizira ma hoses awa kugwira ntchito mokhazikika kwa nthawi yayitali kutentha ndi malo ovuta mankhwala.

2. Kupanga mafakitale: M'makampani opanga mafakitale,EPDM mphira mapaipindi oyenera mayendedwe osiyanasiyana mankhwala TV, kuphatikizapo madzi, nthunzi, asidi ndi alkali njira, etc. Iwo nthawi zambiri ntchito zomera mankhwala, zomera mankhwala, mafakitale chakudya ndi madera ena kuonetsetsa otetezeka ndi odalirika zinthu zoyendera pa kupanga. ndondomeko.

3. Makampani omanga: M'makampani omanga,EPDM mphira mapaipiangagwiritsidwe ntchito popereka madzi ndi ngalande m'nyumba. Kutentha kwake kutentha kumapangitsa kuti payipiyo ikhalebe yogwiritsidwa ntchito bwino m'madera otentha kwambiri m'chilimwe, kupereka zitsimikizo zamphamvu zogwirira ntchito bwino za nyumba.

4. Zomangamanga zotetezera zachilengedwe: Mapaipi a rabara a EPDM amakhalanso ndi gawo lofunika kwambiri pa zomangamanga zoteteza chilengedwe. Amagwiritsidwa ntchito kwambiri m'mafakitale opangira madzi otayira, kuyeretsa zimbudzi ndi kutulutsa, ndipo amatha kupirira zofalitsa zina zowononga komanso kutentha kwambiri kuti zitsimikizire kuti malo oteteza zachilengedwe akugwira ntchito mokhazikika.

5. Ulimi: M’munda waulimi,EPDM mphira mapaipiamagwiritsidwa ntchito nthawi zambiri m'machitidwe a ulimi wothirira m'minda, machitidwe opopera mbewu zaulimi, kayendedwe ka feteleza waulimi, ndi zina zotero. Zotsutsana ndi ukalamba ndi zotsutsana ndi ultraviolet zimathandiza kuti payipi igwiritsidwe ntchito kwa nthawi yaitali m'madera akunja, kupereka chithandizo champhamvu cha ulimi.

Powombetsa mkota,EPDM rabara payipiyawonetsa kuthekera kogwiritsa ntchito kwambiri m'mafakitale ambiri ndi magwiridwe ake abwino komanso magawo ambiri ogwiritsira ntchito. Ndi kukula mosalekeza ndi kukula kwaZebungTekinoloje, magwiridwe antchito ndi magawo ogwiritsira ntchitoEPDM rabara payipiidzakulitsidwa ndi kukonzedwanso, kupereka mayankho apamwamba kwambiri komanso odalirika kwa mafakitale ambiri.
