Nsalu zomata za Nkhata Bay zomata Nsalu za Nkhata Bay za akazi nsapato ndi matumba

Mtengo wa softwood cork (wotchedwa cork oak kunja) ndi wovuta kuti ugwirizane ndi nyengo yozizira komanso yotentha kwambiri. Nthawi zambiri imamera m'nkhalango zamapiri pamtunda wa 400-2000 metres m'malo otentha komanso otentha. Pakati pa 32 mpaka 35 madigiri kumpoto kwa latitude, zinthu za kork zimapezeka m'madera ambiri amapiri omwe amakwaniritsa malo ndi nyengo. Mwachitsanzo, Portugal, Spain, dera la kum'mwera kwa France, komanso mapiri a Qinba m'dziko langa, kum'mwera chakumadzulo kwa Henan, Algeria, ndi zina zotero.
Dziko la Portugal ndilofunika kwambiri padziko lonse lapansi pogulitsa cork kunja ndipo limadziwika kuti "Kingdom of Cork" chifukwa cha nyengo yake yapadera ya ku Mediterranean, yomwe ili yoyenera kukulitsa zipangizo za kok. Panthawi imodzimodziyo, dziko la Portugal ndi dziko loyambirira kwambiri padziko lonse lapansi pakupanga zinthu za nkhokwe, kutumiza kunja kwa zinthu zopangira, komanso kukonza zinthu mozama. limodzi mwa mayiko. Kupanga mitengo yofewa ku Algeria ndi imodzi mwazinthu zapamwamba kwambiri padziko lonse lapansi.
Mapiri a Qinba ku Shaanxi, m'dziko langa, alinso ndi chuma chochuluka, chomwe chimaposa 50% ya chuma cha dzikolo. Choncho, Shaanxi amadziwika kuti "Cork Capital" mu makampani. Kutengera mwayi wopeza izi, opanga zinkhanira zazikulu zapakhomo amakhala makamaka pano.
Nkhata Bay imapangidwa ndi maselo ambiri athyathyathya omwe amapangidwa mozungulira. Maselo a cell nthawi zambiri amakhala ndi utomoni ndi tannin, ndipo ma cell amadzazidwa ndi mpweya. Choncho, cork nthawi zambiri imakhala yamitundu, yopepuka komanso yofewa, yotanuka, yosasunthika, yosasunthika ku zotsatira za mankhwala, ndipo ndi woyendetsa bwino wa magetsi, kutentha ndi phokoso. Amapangidwa ndi ma cell akufa ammbali 14 opangidwa mozungulira kuchokera kwa wina ndi mnzake mumtundu wa hexagonal prism. Ma cell awiri ake ndi ma microns 30 ndipo makulidwe a cell ndi 1 mpaka 2 microns. Pali ma ducts pakati pa ma cell. Danga pakati pa maselo awiri oyandikana nawo limapangidwa ndi zigawo za 5, ziwiri zomwe zimakhala za fibrous, zotsatiridwa ndi zigawo ziwiri za suberized, ndi matabwa pakati. Pali maselo opitilira 50 miliyoni pa kiyubiki centimita imodzi. .
khalidwe
Kapangidwe kameneka kamapangitsa khungu la cork kukhala ndi elasticity yabwino kwambiri, kusindikiza, kutsekereza kutentha, kutulutsa mawu, kutsekereza magetsi komanso kukana kukangana. Kuphatikiza apo, sizowopsa, zopanda fungo, zazing'ono zamphamvu yokoka, zofewa mpaka kukhudza, ndipo sizivuta kugwira moto. Ilibebe zopangidwa ndi Munthu zomwe zingafanane. Pankhani ya mankhwala, ester osakaniza opangidwa ndi angapo hydroxy mafuta zidulo ndi phenolic zidulo ndi khalidwe chigawo chimodzi cha Nkhata Bay, pamodzi amatchedwa suberin.
Mtundu uwu wa zinthu kugonjetsedwa ndi dzimbiri ndi mankhwala kuukira. Choncho, kuwonjezera pa kukhala dzimbiri kwa anaikira nitric asidi, anaikira sulfuric asidi, chlorine, ayodini, etc., alibe mankhwala zimakhudza madzi, mafuta, mafuta, organic zidulo, mchere, esters, etc. Iwo ali osiyanasiyana a amagwiritsa ntchito, monga zoyimitsa mabotolo, zotchingira zida za firiji, ma lifebuoys, mapanelo otsekereza mawu, ndi zina.
Zogulitsa
①Zogulitsa zachilengedwe. Pambuyo kuphika, kufewetsa ndi kuyanika, imadulidwa mwachindunji, kusindikizidwa, kutembenuzidwa ndi njira zina zopangira zinthu zomalizidwa monga mapulagi, mapepala, ntchito zamanja, ndi zina zotero.
② Zinthu zophika nkhokwe. Zida zotsalira za mankhwala a cork achilengedwe zimaphwanyidwa ndikuphwanyidwa m'mawonekedwe, zophikidwa mu uvuni pa 260 mpaka 316 ° C kwa maola 1 mpaka 1.5, ndiyeno zitakhazikika mu njerwa za cork kuti muzitha kutentha pang'ono. Itha kupangidwanso ndi njira yotenthetsera nthunzi yotentha kwambiri.
③Zopangidwa ndi simenti. Tinthu tating'onoting'ono tating'onoting'ono timasakanizidwa ndi ufa ndi zomatira (monga utomoni, mphira) ndikukanikizidwa muzinthu zomata simenti, monga ma veneers, matabwa otchinjiriza mawu, matabwa otchinjiriza kutentha, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, zombo, makina, zomangamanga, etc.
④Zinthu za rabara. Amapangidwa ndi ufa wa cork ngati zopangira komanso pafupifupi 70% ya mphira. Lili ndi compressibility wa Nkhata Bay ndi elasticity wa mphira. Amagwiritsidwa ntchito kwambiri ngati zida zapamwamba zotsika komanso zapakatikati zosindikizira zama injini, ndi zina zambiri, komanso zitha kugwiritsidwa ntchito ngati anti-seismic, kutchinjiriza kwamawu, zida zogundana, ndi zina zambiri.
