Mica ndi dzina la mchere wosanjikiza, wokhala ndi mawonekedwe osungunuka, kuwonekera poyera, kutentha kwa kutentha, kukana dzimbiri, kupatukana kosavuta ndikuvula ndikuzaza zonse. Amagwiritsidwa ntchito kwambiri popanga zodzoladzola, mapulasitiki, mphira, zokutira, kuteteza dzimbiri, zokongoletsa, kuwotcherera, kuponyera, zomangira ndi zina, zomwe zimachita mbali yofunika kwambiri pazachuma ndi zomangamanga.
I. Kafukufuku ndi chitukuko cha mica yopanga
Malinga ndi "synta mica", ku 1887, asayansi aku Russia adagwiritsa ntchito fluoride kuti apange chidutswa choyamba cha fluoropoly mica kuchokera kusungunuka; Pofika mu 1897, Russia idaphunzira momwe mapangidwe amaminerizer amathandizira. Mu 1919, kampani yaku Germany Siemens - Halske idapeza chilolezo choyamba ya mica yopanga; United States yatenga zotsatira zonse zakapangidwe kazinthu zopanga mica pambuyo pa nkhondo yachiwiri yapadziko lonse .Kuti kutentha kwambiri kukana, ndichinthu chofunikira podzitchinjiriza ndi ukadaulo, United state idapitilizabe kufufuzaku.
Pachigawo choyambirira pg China, mica yachilengedwe imatha kukhutitsa chuma ndi chitukuko cha dziko. Komabe, ndikukula kwachangu kwa mphamvu, msika wamalengalenga, mica yachilengedwe sinathenso kukwaniritsa zofunikira. Mabungwe ena achi China adayamba kuphunzira zopanga mica.
Mabungwe ofufuza zasayansi limodzi ndi masukulu, maboma ndi mabizinesi amapanga kafukufuku ndikupanga mica yokhayokha idakhazikika mpaka pano.
II. Ubwino wopanga mica poyerekeza ndi mica yachilengedwe
(1) Khola labwino chifukwa chofanana ndi kuchuluka kwa zinthu zopangira
(2) Kuyera kwambiri & kutchinjiriza; palibe gwero la radiation
(3) Chitsulo chochepa kwambiri, chimakumana ndi mulingo waku Europe ndi United.
(4) High luster ndi whiteness (> 92), zinthu za siliva ngale ya pigment.
(5) Zofunika za pigment ngale ndi galasi
III. Kugwiritsa Ntchito Kwambiri kwa Mica Yopanga
Mumakampani a mica, ndikofunikira kugwiritsa ntchito zidutswa za mica pambali pa pepala lalikulu la mica Nayi momwe mungagwiritsire ntchito mica yopanga motere:
(1) apanga mica ufa
Mawonekedwe: Kutsetsereka bwino, kuphimba kwamphamvu ndi kumata.
Ntchito: coating kuyanika, ceramic, anti-corrosion ndi makampani azamagetsi.
Huajing kupanga mica ali ndi zomangamanga kwathunthu, kuwonetseredwa ndi mawonekedwe akulu, omwe ndi zinthu zabwino kwambiri za ngale ya ngale.
(2) Kupanga mica zoumbaumba
Kupanga mica ziwiya zadothi ndi mtundu wa gulu, amene ali ndi ubwino wa mica, ziwiya zadothi ndi mapulasitiki. Imakhala ndi kukhazikika kwamphamvu, kutchinjiriza kwabwino, komanso kutentha.
(3) Zotayira
Ndi mtundu watsopano wa zochita kupanga kutchinjiriza ndi kutentha kukana, ndi odana ndi dzimbiri.
Mwayi: kutchinjiriza mkulu, mphamvu mawotchi, cheza kukana, kukana makutidwe ndi okosijeni ndi zina zotero.
(4) Kupanga mica magetsi Kutentha mbale
Ichi ndi chinthu chatsopano chogwirira ntchito, chomwe chimapangidwa ndikuphimba kansalu kakang'ono ka semiconductor pa mbale yopanga mica. Monga chida cha zida zapanyumba, ilibe utsi komanso yopanda tanthauzo kutentha kwambiri, chifukwa chake ikugwiritsidwa ntchito kwambiri ndikupanga mwachangu masiku ano.
(5) Kupanga mica ngale pigment
Popeza ma mica opanga ndiopangira zinthu, zinthuzo zimatha kuyendetsedwa bwino. Chifukwa chake, chitsulo cholemera ndi zinthu zina zoyipa zitha kupewedwa kuyambira pachiyambi .M mica yopanga imakhala yoyera kwambiri, yoyera, kunyezimira, chitetezo, yopanda poizoni, kuteteza zachilengedwe, komanso kutentha kwambiri. zikopa, zodzoladzola, nsalu, ceramic, zomangamanga komanso zokongoletsa.Ndi chitukuko chowonjezeka cha ukadaulo wopanga wa mica, umathandizira kwambiri m'moyo watsiku ndi tsiku, mafakitale omwe akukhudzana nawo amalimbikitsa mwachangu.
