Kodi Chlorinated Polyethylene (cpe) ndi Kodi Imagwiritsidwa Ntchito Kuti?
Argonated polyethylene cpe low density polyethylene 2 silikoni yophatikizira chingwe cholumikizira chingwe ndi polyethylene yotsika (LDPE) ndi polydimethylsiloxane yophatikizidwa ndi ethyl methacrylate (EMA) (PDMS) yophatikiza mphira ndi chida chogwira ntchito chosagwira kutentha chingwe.Mitundu yosiyanasiyana yamagetsi, zida zamakina ndi kutentha kwamafuta osakanikiranawo zidaphunziridwa.Zotsatira zikuwonetsa kuti kuphatikizako kumatha kugwiritsidwa ntchito ngati chinthu chosungunulira cha Thermal, poyerekeza ndi zida za mphira za silicone, zimakhala ndi mtengo wabwinoko.
Kwa nthawi yayitali, anthu amawona mphira wa silikoni ngati mphira wapadera wa zingwe mumitundu yosiyanasiyana yotentha komanso yotsika.Komabe, mtengo wamtengo wapatali wa rabara ya silikoni umalepheretsa kugwiritsa ntchito kwake.
LDPE ndiye pulasitiki wokhala ndi ndalama zambiri m'makampani.Ili ndi mtengo wotsika komanso wabwino kwambiri wamagetsi, motero imagwiritsidwa ntchito kwambiri ngati polima yotchingira mawaya apakati ndi otsika ndi zingwe.LDPE siyotsika mtengo komanso yotsika mtengo komanso yotsika kwambiri ya dielectric ndi kutayika, kupirira kwakukulu, komanso makina abwino kwambiri otsika kutentha kwa 90C, kotero mphira ambiri opangidwa, monga mphira wa styrene-butadiene (SBR), mphira wa butyl (IR) ), neoprene(CR) ndi zina zotero ataya gawo la msika.Poyerekeza ndi zinthu zotchinjiriza za mphira wa silikoni, kuphatikiza kwa polydimethylsiloxane (PDMS) ndi LDPE kuli ndi mwayi wotsika mtengo kuti ukwaniritse magiredi osiyanasiyana, Kuphatikiza pa zofunikira zapadera za zingwe zotumizira mphamvu, kuwongolera ndi zida, anthu apitiliza kupanga. zida zatsopano zotchinjiriza za polima.Komabe, mphamvu zamakina ndi kukana kutentha kwamagetsi otsika kwambiri (<10kV) ndi apamwamba kuposa
Mphamvu zamagetsi ndizofunika kwambiri.
Mwachitsanzo;chingwe chotchinjiriza chingwe cha ng'anjo chiyenera kukhala ndi kukhazikika kwabwino kwa makina pa kutentha kwakukulu.Mofananamo;zofunikira pazingwe zotsika utsi, zosagwira mafuta, komanso zingwe zosapsa ndi moto ndizosiyananso.Choncho chingwe chiyenera Nthawi yogwiritsira ntchito imatsimikizira zofunikira pa ntchito yapadera ya chingwe.The kuwonongeka kwa okosijeni wa mphira ndi mapangidwe okusayidi wosanjikiza pamwamba kuonjezera madutsidwe, chifukwa mphira ndi oxidized, ndi polarity kwaiye pakati mpweya wakuda aggregates.
Magulu (monga carboxyl) Maguluwa amapereka njira yayifupi ya ma elekitironi.Pali zinthu zingapo zomwe muyenera kuziganizira posankha zomwe mungagwiritse ntchito.Ponena za kusungunula chingwe;chinthu chofunika kwambiri ndi Malire ake mphamvu ya panopa kudutsa wosanjikiza kutchinjiriza.Kwa panopa mwachindunji (dc), n'zoonekeratu kuti kugwiritsa ntchito zipangizo zotsutsa kwambiri kungachepetse makulidwe a wosanjikiza;pakusintha kwapano (ac), kuloledwa kwapang'ono ndi kutayika ndizochepa.
Dissipation factor imachepetsanso makulidwe a insulation.
Ethyl methacrylate (EMA) imatha kusinthidwa kwambiri ndi mphira wa silikoni ngati chinthu chotchinjiriza pogwiritsa ntchito PDMS zophatikizira pazinthu zosiyanasiyana zamagetsi, zida zamakina komanso kukana kutentha.
Kuchita bwino kwa ndalama zomwezo monga zofananira za LDPE ndi PDMSA zikuphatikiza (50:50).
1. Chitetezo chokhazikika, CPE idzatulutsa hydrogen chloride ikatenthedwa kapena kutenthedwa, kotero ma stabilizer okhala ndi asidi mayamwidwe ayenera kugwiritsidwa ntchito mu ndondomeko, monga calcium stearate, barium stearate, tribasic lead sulfate kapena magnesium oxide.
2. Plasticizing dongosolo.Ester plasticizers amagwiritsidwa ntchito kwambiri mu CPEZ, monga dioctyl phthalate (DOP) ndi dioctyl adipate (DOA).Magawo awo osungunuka ali pafupi ndi a CM.Kutha kwabwino.Kugwiritsa ntchito DOA ndi DOS mu rabala kumatha kupatsa mphira ndi kukana kuzizira kwambiri.
3. Dongosolo la vulcanization la CPE, CPE ndi mphira wodzaza, ndipo wamba sulfure vulcanization dongosolo sangathe vulcanize bwino.Kugwiritsa ntchito koyambirira kwa CPE vulcanization system ndi thiourea system, yomwe imagwira ntchito kwambiri ndi Na-22, koma Na-22 imakhala ndi liwiro locheperako, kukalamba kosachita bwino, kupanikizika kwambiri, ndipo Na-22 ndi carcinogen yayikulu.Zimatulutsa fungo losasangalatsa, ndipo kugwiritsidwa ntchito kwake kwaletsedwa kunja.
4. Kulimbitsa dongosolo lodzaza, CPE ndi mtundu wa rabara wosadzilimbitsa, womwe umafuna dongosolo lolimbikitsa kuti lipeze mphamvu zabwino.Njira yake yolimbikitsira yodzaza ndi yofanana ndi zomatira pazolinga zonse.Chothandizira kwambiri chimakhala chakuda chakuda ndi choyera chakuda.Mpweya woyera wakuda ukhoza kupititsa patsogolo kukana kwa misozi ya CPE, ndipo ukhoza kupanga makina oyera a metamethyl kuti apititse patsogolo kumamatira pakati pa CPE ndi mafupa.phatikiza.CPE ili ndi katundu wodzaza kwambiri, ndipo dongosolo lodzaza limaphatikizapo calcium carbonate, talcum powder, dongo, etc.
