Mica Flakes Yasintha Kapangidwe ka Makampani a Mphira Buku Lofotokozera la Odzaza Magwiridwe Abwino Chithunzi Chowonetsedwa

Mica Flakes Yasintha Makampani a Mphira Buku Lophunzitsira Anthu Odzaza Magwiridwe Abwino Kwambiri

Kufotokozera Kwachidule:

Ma Mica flakes, okhala ndi kapangidwe kake ka lamellar, kukhazikika kwapadera kwa mankhwala, komanso kugwirizana kodabwitsa ndi ma matrices a rabara, adzikhazikitsa okha ngati ma filler ogwira ntchito bwino kwambiri mumakampani opanga rabara. Mosiyana ndi ma filler wamba monga carbon black kapena calcium carbonate, ma mica flakes amapereka kuphatikiza kwapadera kwa makina olimbikitsira, kukana nyengo, komanso kukhazikika kwa mawonekedwe, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pazinthu za rabara zomwe zimagwira ntchito m'malo ovuta, kuphatikiza zisindikizo zamagalimoto, mapayipi a rabara amafakitale, ndi malamba otumizira.

Mu gawo la zisindikizo za rabara zamagalimoto, kuphatikizapo zisindikizo za zitseko, zisindikizo za mawindo, ndi ma gasket a injini, ma mica flakes amagwira ntchito yofunika kwambiri pakuwonjezera kukana kwa misozi ndi magwiridwe antchito a seti yokakamiza. Zisindikizo izi zimakumana ndi kupsinjika kwa makina pafupipafupi, kusinthasintha kwakukulu kwa kutentha kuyambira -40°C mpaka 120°C, komanso kuwonetsedwa nthawi yayitali ndi kuwala kwa UV, zinthu zomwe zingayambitse zisindikizo wamba za rabara kusweka, kuuma, kapena kutaya kulimba pakapita nthawi.

Kuwonjezera kwa 8%-15% ya ma mica flakes okhala ndi chiŵerengero chapamwamba, okhala ndi kukula kwa tinthu tating'onoting'ono ta 30-80 μm ndi chiŵerengero cha ≥100, ku rabara ya ethylene-propylene-diene monomer (EPDM) kumabweretsa zotsatira zabwino kwambiri. Mphamvu ya kung'ambika kwa rabara imawonjezeka ndi 40%-60%, pomwe kuchuluka kwa kupsinjika, komwe kumayesedwa pambuyo pa maola 70 pa 100°C, kumatsika kwambiri kuchokera pa 35% mpaka 15%. Wopanga zida zamagalimoto wotsogola ku Germany adachita mayeso ambiri pogwiritsa ntchito ma mica flakes athu mu ma EPDM door seals. Zotsatira zake zinali zodabwitsa: ma seals adasunga kulimba kwawo komanso magwiridwe antchito otseka kwa ma 500,000 otsegulira ndi kutseka, poyerekeza ndi ma 300,000 okha a ma seals opanda ma mica flakes. Nthawi yayitali yogwirira ntchito iyi sikuti imangochepetsa ndalama zokonzera magalimoto komanso kumawonjezera kudalirika kwa zinthu zamagalimoto.

Pa mapayipi a rabara a mafakitale omwe amagwiritsidwa ntchito potumiza mankhwala, mafuta, ndi madzi, ma mica flakes ndi ofunikira kwambiri pakuwonjezera kukana kwa mankhwala ndi kukana kupanikizika. Mapayipi amenewa nthawi zambiri amakumana ndi zinthu zowononga ndipo ayenera kupirira kupsinjika kwakukulu kwamkati mpaka 10 MPa. Ma Mica flakes, okhala ndi kapangidwe kake ka lamellar kosalowa madzi, amapanga chotchinga chothandiza mkati mwa matrix ya rabara, kuchepetsa kulowa kwa mankhwala ndi 50%-70%.

Mukawonjezera mapayipi a nitrile rabara (NBR) pa mlingo wa 10%-20%, ma mica flakes amawonjezera kwambiri kupsinjika kwa payipi ndi 25%-35% ndikuwonjezera moyo wake wogwiritsa ntchito potumiza mafuta kuyambira chaka chimodzi mpaka zaka 2-3. Chomera cha mankhwala ku Netherlands chinayesa mapayipi athu a NBR olimbikitsidwa ndi mica pakutumiza 20% ya sulfuric acid. Zotsatira zake zinali zotsimikizika: patatha miyezi 12 yogwiritsidwa ntchito mosalekeza, mapayipiwo sanawonetse zizindikiro za kutupa kapena kutuluka, pomwe mapayipi wamba a NBR adalephera patatha miyezi 4 yokha. Kuphatikiza apo, ma mica flakes amathandizira kukhazikika kwa mapayipi a rabara, kuchepetsa kuchepa panthawi yotulutsa ndi 15%-25% ndikuwonetsetsa kuti akugwirizana bwino ndi zolumikizira.

Ma mica flakes athu onse amakwaniritsa miyezo yokhwima yamakampani malinga ndi zizindikiro zazikulu zaukadaulo. Chinyezi ndi ≤0.3%, phulusa ≤0.5%, kuyamwa kwa mafuta ≤25 mL/100g, ndipo amalimbana bwino ndi kutentha, amakhalabe olimba kutentha mpaka 600°C. Kuphatikiza apo, zinthu zathu zimagwirizana mokwanira ndi malamulo a RoHS ndi REACH, ndipo chitsulo cholemera chili pansi pa malire a chitetezo padziko lonse lapansi (lead ≤0.0005%, arsenic ≤0.0003%).

Ponena za kayendetsedwe ka zinthu, timaika patsogolo ubwino ndi kukhulupirika kwa zinthu zathu. Ma flakes athu a mica amapakidwa m'matumba osanyowa (25 kg/thumba), okhala ndi filimu yamkati ya polyethylene ndi thumba lakunja la pepala la kraft kuti tipewe kuyamwa kwa chinyezi panthawi yoyendera panyanja. Takhazikitsa mgwirizano wolimba ndi makampani otsogola otumiza katundu monga Maersk ndi COSCO, kuonetsetsa kuti makasitomala athu afika nthawi yake ku Europe, North America, ndi Southeast Asia mkati mwa masiku 15-30.

Mica ndi dzina la mchere wa gulu la mica. Ndi aluminosilicate ya potaziyamu, aluminiyamu, magnesium, chitsulo, lithiamu ndi zitsulo zina, zonse zomwe zimakhala ndi zigawo komanso monoclinic. Kristalo ndi pseudohexagonal lamellae kapena mbale, nthawi zina columnar. Kugawanika kwa lamellar kumakhala kokwanira kwambiri, ndi galasi lowala ndi pepala lolimba. Chizindikiro cha refractive cha mica chimawonjezeka ndi kuchuluka kwa chitsulo, kuyambira kutsika pang'ono mpaka kutsika kwapakati. Mtundu wopanda chitsulo umakhala wopanda utoto mu flake. Chitsulo chikakhala chachikulu, mtundu wake umakhala wakuda kwambiri, ndipo umakhala wochuluka komanso woyamwa.

Kukula kwa chipolopolo cha Mica: 6-10mesh, 10-20mesh,
Ufa wa Mica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh ndi 5000mesh.

Kugwiritsa ntchito
Mu makampani, biotite imagwiritsa ntchito kwambiri kutchinjiriza kwake ndi kukana kutentha, komanso kukana asidi, kukana alkali, kukana kupsinjika ndi kukana kutsekeka, ngati zinthu zotetezera zida zamagetsi ndi zida zamagetsi; kachiwiri, imagwiritsidwa ntchito popanga mawindo ndi zida zamakaniko a boilers a nthunzi ndi uvuni wosungunula. Zidutswa za Mica ndi ufa wa mica zimatha kukonzedwa kukhala pepala la mica, ndipo zimathanso kusintha pepala la mica kuti lipange zinthu zosiyanasiyana zotetezera kutentha zotsika mtengo komanso zofanana.

Muscovite ndi yomwe imagwiritsidwa ntchito kwambiri m'mafakitale, kutsatiridwa ndi phlogopite. Imagwiritsidwa ntchito kwambiri m'mafakitale a zipangizo zomangira, makampani ozimitsa moto, zida zozimitsira moto, ndodo yowotcherera, pulasitiki, zotetezera magetsi, kupanga mapepala, pepala la phula, labala, utoto wa pearlescent ndi mafakitale ena a mankhwala.

Ufa wa mica wosalala kwambiri umagwiritsidwa ntchito ngati chodzaza chogwira ntchito cha pulasitiki, utoto, utoto, rabara ndi zina zotero, zomwe zimatha kulimbitsa mphamvu zake zamakanika, kulimbitsa kulimba, kumatira, kuletsa ukalamba komanso kukana dzimbiri.
