Zogulitsa zotentha zamtundu wa cork board miyala ya EVA yachikopa cha rabara yachikopa azimayi ndi nsapato

Chidziwitso choyambirira cha kork.
Zomwe zimadziwika kuti cork ndi cork zomera, ndizopangidwa ndi makungwa akunja amtundu wamtundu wamtengo wapatali wopangidwa kwambiri, ndipo ndi minofu yoteteza pamwamba pa tsinde ndi mizu itatha kukhuthala ndikukula. Khungwa la oak limapezeka makamaka m'mayiko asanu ndi awiri omwe ali kumadzulo kwa nyanja ya Mediterranean, Algeria, ndi Tunisia. Palinso zokolola zochepa m'mapiri a Qinling a dziko langa. Lili ndi nayitrogeni wina ndipo lili ndi potaziyamu wambiri. Mtengo wa pH umafika pa 5160 mpaka 800 mm. Kutentha sikutsika kuposa madigiri a 5 chaka chonse ndipo kumakhudzidwa ndi mphepo ya Atlantic. Chifukwa chake, chilengedwe chabwino cha Portugal chimapangitsa kukhala ufumu wodziwika padziko lonse lapansi wa nkhokwe. Zomwe zimatuluka komanso mtundu wa nkhuni ndi zinthu zake zimayambira 30% padziko lapansi.
Kugawidwa kwa chiyambi cha softwood.
Kutulutsa 50% ya zinthu zopangira nkhuni, 32% ya Portugal imapangidwa ku Spain, 6% imapangidwa ku Italy, zopitilira 50% zimakhazikika m'manda a Aigupto zaka masauzande zapitazo, ndipo zoyimitsa za cork zapezeka. China ili ndi zolemba za cork mu Nyengo ya Spring ndi Yophukira. Kale ku Girisi, khungwa la nkhuni linkagwiritsidwa ntchito ngati zoyandama pa maukonde ophera nsomba komanso ngati zokometsera tsitsi pa nsapato. Mu 1680, zipatsozo zinali zabwino kwambiri. Ichi ndiye chitukuko chofunikira kwambiri chamakampani a cork.
Kukula kwa makampani a Nkhata Bay
Kukula kwakukulu kwa makampani a nkhokwe kunayamba chakumapeto kwa zaka za m'ma 1800, pamene JHNSMITH, wa ku America, adapeza kuti nkhokwe ikhoza kupangidwa kukhala zinthu zopangidwa ndi cork. Khungu lomwe limapezeka pakukolola koyambirira ndi kusenda kwa zinthu zosawerengeka zimatchedwa khungu loyamba kapena khungu loyambirira. Zabwino kwambiri zimatha kufika 6-8 centimita, ndipo moyo wawo ndi pafupifupi zaka 200. Cork imapangidwa ndi ma cell athyathyathyathya, ndipo cell cavity nthawi zambiri imakhala ndi utomoni ndi tannin mankhwala, omwe ndi zotsatira za mankhwala ndipo ndi oyendetsa bwino magetsi, kutentha ndi phokoso. Amapangidwa ndi maselo akufa mu mawonekedwe a 14-hedron, okonzedwa mozungulira kuchokera kwa wina ndi mzake mumtundu wa hexagonal prism. Ma cell awiri ake ndi ma microns 30. Palibe njira pakati pa ma cell. Nthawi yapakati pa ma cell awiri oyandikana imapangidwa ndi zigawo zisanu, ziwiri zomwe ndi ulusi. katundu, kutsatiridwa ndi zigawo ziwiri za corkization, ndi wosanjikiza wa lignification pakati. Pali maselo oposa 40 miliyoni mu 1 kiyubiki centimita iliyonse, ndipo mpweya wotsalira mu cell cavity umakhala ndi 70% ya voliyumu ya unit, kotero Nkhata Bay Ndi chinthu chopepuka, ndipo mipata pakati pa maselo oyandikana imadzazidwa ndi utomoni. Pangani selo lililonse kuti likhale lopanda mpweya komanso lotsekedwa ndi madzi.
Katundu wa Nkhata Bay.
Ndilo mawonekedwe apadera a cell ndi mankhwala a cork youma omwe amapangitsa kuti azikhala ndi mpweya wabwino, kutsekemera kwamphamvu, kuyamwa kwabwino kwambiri, kudzipatula, kukana dzimbiri, kukana chinyezi, kukana kuvala, kuteteza moto ndi zinthu zina. Nkhakwe imakhala ndi kukhuthala kwabwino kwambiri, kusindikiza, kutsekereza kutentha, kutsekereza mawu, komanso sikophweka kugwira moto. Palibe chinthu chopangidwa ndi anthu chomwe chingafanane nazo. Pankhani ya chemical properties,
Cork amagwiritsa ntchito:
Nthawi zambiri amatchedwa utomoni wa softwood, chinthu chamtunduwu sichimawola komanso kuwononga mankhwala. Choncho, kuwonjezera pa kukhala zikuwononga kuti anaikira nitric asidi, anaikira sulfuric asidi, chlorine, ayodini, etc., si kugonjetsedwa ndi madzi, mafuta, mafuta, organic zidulo, mchere, esters, etc. Act mankhwala. Zili ndi ntchito zosiyanasiyana, monga kupanga zoyimitsa mabotolo ndi zotchingira zida za firiji. Nkhata zachilengedwe zimatenthedwa, kuzifewetsa, ndi kuziumitsa ndiyeno kuzidula mwachindunji, kuzisindikiza, ndi kusandulika kukhala zinthu zomalizidwa, monga zoyimitsira, zoyala, zamanja, ndi zinthu zina zowotcha. . Zinthu zotsalira za zinthu zachilengedwe za Nkhata Bay zimaphwanyidwa ndikukanikizidwa kuti zipange njerwa zotentha. Njira yotenthetsera kwambiri ya nthunzi ingagwiritsidwenso ntchito popanga zinthu zokhala ndi simenti, monga zotsekera pansi, matabwa otchingira mawu, matabwa otchinjiriza kutentha, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, zombo, makina, zomangamanga, ndi zina zambiri. Pafupifupi 70% ya rabala imapangidwa kuchokera ku ufa wa cork. Lili ndi compressibility wa Nkhata Bay ndi elasticity wa mphira. Amagwiritsidwa ntchito kwambiri ngati zida zapamwamba zotsika komanso zapakatikati zosindikizira zama injini ndi injini zina. Itha kugwiritsidwanso ntchito kukana zivomezi, kutchinjiriza mawu, zida za Friction, ndi zina.
Cork pomanga
Makoko khoma mapanelo: Kutsekera kwa mawu pansi kopangidwa ndi zida zakhoma kumapangitsa kuti m'nyumba mukhale bata komanso kutentha kwamkati. Panthawi imodzimodziyo, cork ndi chinthu chamatabwa chokhala ndi "B2" mlingo wotsutsa moto ndi katundu wozimitsa okha, ndikupangitsa kukhala mtsogoleri wa zipangizo zotetezera khalidwe. Wolemba. The elasticity wabwino wa Nkhata Bay zimathandiza kuti asunge synchronous kusintha pambuyo zakhala zakhala zikuzunza m'miyoyo ndi zipika, kuchotsa nkhawa. Guluu umagwiritsidwa ntchito pa drywall ndipo pansi kumakhala zotanuka. Mtunda pakati pa anthu ndi malo ukuyandikira. Makoma ndi pansi amakongoletsedwa ndi makoma a kork. Ziribe kanthu mtundu wa mipando kapena zipangizo zomwe zikuwonekera, chithunzi chogwirizana bwino chimapangidwa. . Deta ya sayansi ndi zamakono zimatsimikizira kuti anthu akangotuluka m'malo aphokoso, adzapeza malo opanda phokoso komanso otentha omwe amakhala omasuka komanso amphamvu.
Kusintha kwa chilengedwe pa thanzi
M'malo oterowo, kutopa pambuyo paulendo watsiku kumatha kuthetsedwa, ndipo nyamakazi sizichitika kawirikawiri ngati mukhala nthawi yayitali.
Gulu la mkati mwa khoma ndi zokongoletsera zapansi zomwe zimagwiritsidwa ntchito m'nyumba
Khoma lamkati ndi zokongoletsera zapansi zomwe zimagwiritsidwa ntchito m'nyumba zakunja zakunja ndi nyumba zaminda zamatawuni zitha kugawidwa m'magulu atatu: utoto wa latex, makapeti ndi pansi pamatabwa. Ma board okongoletsera a cork omwe angopangidwa kumene ndi gulu lomwe langoyamba kumene, ndi ambiri Chifukwa chachikulu cha chizolowezi chosinthira ndikuti ali ndi ntchito zambiri zokongoletsera, masitayelo olemera, ndipo sizibweretsa zotsatira zoyipa mthupi la munthu.
Makhalidwe a kork.
Pali mitundu yambiri ya zingwe, zomwe zimatha kupangidwa molingana ndi kapangidwe kake ndikuziphatikiza m'mitundu ndi mitundu yosiyanasiyana. Ntchito yomangayi ndi yosavuta ndipo imatha kuikidwa pakhoma kapena pansi.
Zochitika zogwiritsira ntchito Cork
Mu zokongoletsera zamalaibulale, ma kindergartens, masewera olimbitsa thupi, zipinda zamakompyuta, ndi zina zotero, ndi chitukuko cha makampani okongoletsera amakono, makoma owuma ndi zipangizo zapansi zimaphatikizidwa.
Kugwirizana pakati pa zinthu zokongoletsera ndi anthu
Psychology ndi chilengedwe zimagwirizana bwino ndi anthu. Zotsatira zokongoletsa za matabwa a VC, mabulosi, ndi zina zambiri ndizodzaza ndi zowoneka bwino komanso zamphamvu zamunthu.
