Pamene munthu ali ndi zakudya zosakhazikika, kudzikundikira kwa calcium oxalate chifukwa cha mapuloteni apamwamba, kapena kudzikundikira kwa zinyalala chifukwa cha mafuta ambiri ndi shuga, kapena kuyika mchere wa mkodzo chifukwa cha moyo wongokhala, kungayambitse mapangidwe a miyala.Ndipo kuyipitsa nkhungu ndi mpweya pang'ono kuchokera ku pulasitiki wosungunuka ndipo pambuyo pa kudzikundikira kwa nthawi, mu nkhungu pamwamba opangidwa ndi adhesion.Kamodzi nkhungu pamwamba pa nkhungu sikelo Ufumuyo, wotsatira nkhungu sikelo kudzikundikira adzakhala mofulumira ndi mofulumira.

Kuwonongeka kwa nkhungu pamwamba pa nkhungu

Miyala ndi kudzikundikira kashiamu oxalate ndi zinyalala zina kuchokera ingested zakudya;ma depositi a nkhungu ndi zowonjezera mamolekyu ang'onoang'ono monga zoletsa malawi ndi mafuta odzola, komanso akhoza kukhala oligomers chifukwa cha kuwonongeka kwa kutentha.Asanakhale "mwala", mulingo wa nkhungu ukhoza kukhala kuphulika kwa mpweya komwe sikumakhudza kupanga ngati kutayidwa nthawi.Monga mkodzo wamchere wa calcium oxalate patsogolo pa mwala, palibe vuto kumwa madzi ochulukirapo ndikuchotsa nthawi yake.Kuwonongeka kwa nkhungu ndikufanana ndi njira ndi njira yopangiranso miyala.Kuwonongeka kwa nkhungu kumatha kutsekereza njira yotulutsa mpweya, kupangitsa kuti zinthu zapulasitiki zipse, zimathanso kumamatira kuzinthu zomwe zimakhudza mawonekedwe, chifukwa kuipitsidwa kwa thupi lakunja kungakhudzenso mphamvu zamagetsi za chinthucho.Processing fakitale amayenera kuyeretsa nkhungu pamene akupanga, ndipo pali kuthekera kuti zinthu zolakwika zinatuluka pamene iwo sanali kuzidziwa izo pa siteji oyambirira.

Zimaumba ziyenera kupukuta ndi phala la diamondi maola angapo aliwonse

Nkhaniyi kulankhula za zomwe zimayambitsa nkhungu madipoziti kuchokera mbali zitatu zazikulu: zakuthupi, ndondomeko ndi nkhungu.Nkhaniyi kulankhula za zomwe zimayambitsa nkhungu madipoziti kuchokera mbali zitatu zazikulu: zakuthupi, ndondomeko ndi nkhungu.

1Zakuthupi

Chuma nthawi zambiri chimakhala chifukwa chachikulu chowonekera cha zolakwika za nkhungu.Nthawi zambiri amawunikidwa kuchokera pamalingaliro atatu otsatirawa.

Choyamba ndikuwonongeka kwa pulasitiki utomoni.Utomoni m'malo opitilira kutentha kwake kuti upangitse ma oligomers, kuwonongeka kumatsatiridwa pakumanga zambiri, zomwe zimawoneka pakusungunuka kwa kutentha pakati pa zinthu za aloyi.Zotsalira zotsalira za ma resin osiyanasiyana zimakhalanso ndi mphamvu.

Chachiwiri ndimvula yazing'ono zowonjezera ma molekyulu.Mapulasitiki osinthidwa adzawonjezedwa ku mapangidwe a zowonjezera zosiyanasiyana kuti apereke zinthuzo kuti zigwire ntchito kapena ntchito yoyenera, mvula pamtunda wamafuta nthawi zambiri imakhala ndi zowonjezera, choncho zimakhala zosavuta kukhala zowonongeka zowonongeka zomwe zimagwirizanitsidwa nazo panthawi yowumba.

Chachitatu ndimphamvu ya pigment.Thermoplastic engineering mapulasitiki mu pigment kusungunuka pa kutentha kwambiri, kuchepetsa kukhazikika matenthedwe akamaumba zinthu, kuchititsa kuwonongeka kwa polima ndi kuwonongeka kwa pigment kuphatikiza kupanga nkhungu fouling.

2Njira Yopangira

Mamolekyu ang'onoang'ono a zowonjezera, zinthu zowola utomoni ndi oligomers ena, kutentha kwambiri poyamba mu mawonekedwe a gasification kapena liquefaction, kukhudzana ndi nkhungu utakhazikika ndi Ufumuyo nkhungu, m'munsi kutentha kwa nkhungu pamwamba, m'pamenenso nkhungu fouling Ufumuyo. .

Mitengo yosiyana ya kupanga sikelo ya nkhungu pa kutentha kwakukulu ndi kutentha kwa nkhungu

Kuchepetsa liwiro la jekeseni pamalo enaake a mankhwala kungathenso kutalikitsa nthawi yoti nkhungu ziwoneke.Ngati liwiro la jekeseni ndilothamanga kwambiri polowera mpweya, mpweya wa oligomer sudzakhala ndi nthawi yokwanira yotuluka mu nkhungu;ngati liwiro la jekeseni liri mofulumira kwambiri pakhoma lopyapyala kapena malo angodya, zidzapangitsa kuti kumeta ubweya weniweni kupitirire kumeta ubweya wa zinthuzo.

3Kukonzekera kwa Nkhungu Ndi Kusamalira

Ndiotentha wothamanga akamaumba ndi kutentha tcheru zipangizo, nthawi yokhalamo yosungunuka idzakhala yayitali, motero kuonjezera chiopsezo cha nkhungu chifukwa cha kuwonongeka kwa zinthu zopangira.Chifukwa chake, makina opangira jekeseni ayenera kutsukidwa.

Kutuluka kwa nkhungu, ngati makina opangira mpweya apangidwa bwino kuti achotse ma oligomers a vaporized kapena liquefied kuchokera mu nkhungu panthawi yake nkhungu isanayambe kusungunuka, chinthu chosokoneza nkhungu chidzafookanso.

Kupanga zida zodziwikiratu,zinthu zoterezi nthawi zambiri zimagwiritsa ntchito othamanga ndi zitseko zazikulu, mazenera amitundu yambiri amatha kuchepetsa mtunda wothamanga, kuthamanga kwa jekeseni wochepa komanso kuchepetsa chiopsezo cha mapangidwe a nkhungu.

Nkhungu madipoziti zosavuta kuchotsa mu magawo oyambirira mapangidwe, kotero kuti zibowo za nkhungu ndi ngalande zotulutsa mpweya ziyenera kutsukidwa ndi kusamalidwa nthawi zonse, mwachitsanzo pambuyo popanga dongosolo lililonse.Ngati nkhunguyo siisungidwa ndi kutumikiridwa kwa nthawi yayitali, zimakhala zovuta kuchotsa zigawo zazikulu za nkhungu zomwe zimapangidwira.

Zopaka zopanda ndodo, zokutira zapadera zopanda ndodo (monga zokutira za PVD) pazitsulo zamkati zimatha kuletsa mapangidwe a nkhungu ndipo ziyenera kuyesedwa kuti ziwone momwe zokutirazo zikuyendera.Titaniyamu nitride mankhwala pa mkati padziko nkhungu angalepheretse mapangidwe nkhungu fouling pa nkhungu.

Kumangira jekeseni kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo kumatha kukwaniritsa kupanga kosasunthika, kolondola kwambiri kwa magawo munthawi yochepa.PorLean Tech imapereka ntchito zopangira jakisoni pazinthu zambiri, kuphatikiza mapulasitiki ndi ma elastomer.Mwachidule kwezani chitsanzo chanundipo pezani mawu ofulumira aulere ndi malangizo okhudzana ndi mautumiki.
