Amazi adashobora kwihanganira amazi ya cork yimyenda yimyenda ya cork kubagore inkweto namashashi

Igiti cyitwa corkwood cork (cyitwa cork oak mumahanga) biragoye guhuza nikirere gikonje nubushyuhe bwinshi. Ubusanzwe ikurira mu mashyamba yo ku misozi ku butumburuke bwa metero 400-2000 mu turere dushyuha kandi dushyuha. Mu burebure bwa dogere 32 kugeza kuri 35 z'uburebure, umutungo wa cork urashobora kuboneka mumisozi myinshi yujuje imiterere yimiterere yikirere. Kurugero, Porutugali, Espagne, akarere k'amajyepfo y'Ubufaransa, ndetse n'imisozi ya Qinba mu gihugu cyanjye, mu majyepfo y'uburengerazuba bwa Henan, Alijeriya, n'ibindi.
Porutugali iza ku mwanya wa mbere ku isi mu byoherezwa mu mahanga kandi izwi ku izina rya "Ubwami bwa Cork" kubera ikirere cyihariye cya Mediterane, gikwiranye no gukura kw'ibikoresho fatizo bya cork. Muri icyo gihe, Porutugali ni yo ya mbere ku isi mu guteza imbere umutungo wa cork, kohereza ibicuruzwa hanze, no gutunganya cyane ibicuruzwa. kimwe mu bihugu. Umusaruro wa softwood wo muri Alijeriya uri mu myanya ya mbere ku isi.
Imisozi ya Qinba muri Shaanxi, igihugu cyanjye, nayo ikungahaye ku mutungo wa cork, bingana na 50% by'umutungo wa cork mu gihugu. Kubwibyo, Shaanxi azwi nka "Umurwa mukuru wa Cork" mu nganda. Dushingiye kuriyi nyungu yibikoresho, uruganda runini rwa cork murugo rwibanze cyane hano.
Cork igizwe ningirabuzimafatizo nyinshi zitunganijwe neza. Akagari ka selile akenshi karimo resin na tannin, kandi selile zuzuye umwuka. Kubwibyo, cork ikunze kuba ibara, urumuri kandi rworoshye, rworoshye, ntirwinjira, ntirushobora guhura ningaruka ziterwa nimiti, kandi ni umuyoboro mubi w'amashanyarazi, ubushyuhe nijwi. Igizwe ningirabuzimafatizo 14 zipfuye zitunganijwe muburyo butandukanye hagati yuburyo butandatu bwa prism. Ubusanzwe diameter ya selile ni microne 30 naho uburebure bwa selile ni microni 1 kugeza 2. Hariho imiyoboro hagati ya selile. Umwanya uri hagati ya selile ebyiri zegeranye ugizwe nibice 5, bibiri muri byo ni fibrous, bigakurikirwa nuburyo bubiri munsi, hamwe nigiti cyibiti hagati. Hano hari selile zirenga miliyoni 50 kuri santimetero 1. .
biranga
Iyi miterere ituma uruhu rwa cork rufite ubuhanga bukomeye cyane, gufunga, kubika ubushyuhe, kubika amajwi, kubika amashanyarazi no kurwanya ubukana. Mubyongeyeho, ntabwo ari uburozi, nta mpumuro nziza, ntoya muburemere bwihariye, yoroshye gukoraho, kandi ntabwo byoroshye gufata umuriro. Ntabwo igifite ibicuruzwa byakozwe n'abantu biragereranywa. Kubijyanye nimiterere yimiti, imvange ya ester ikozwe na hydroxy fatty acide na acide ya fenolike nikintu kiranga cork, hamwe bita suberin.
Ubu bwoko bwibikoresho birwanya ruswa hamwe nigitero cyimiti. Kubwibyo, usibye kwangirika kuri acide ya nitricike, aside sulfurike yibanze, chlorine, iyode, nibindi, ntabwo bigira ingaruka kumiti kumazi, amavuta, lisansi, acide organic, umunyu, esters, nibindi. Ifite intera nini ikoresha, nk'icupa rihagarika, ibice byo kubika ibikoresho bya firigo, ubuzima bwubuzima, ibyuma byerekana amajwi, nibindi.
Ibicuruzwa
Products Ibicuruzwa bisanzwe bya cork. Nyuma yo guteka, koroshya no gukama, iracibwa mu buryo butaziguye, kashe, ihindurwa nubundi buryo bwo gukora ibicuruzwa byarangiye nkibicomeka, amakariso, ubukorikori, nibindi.
Products Ibicuruzwa bya cork bitetse. Ibikoresho bisigaye byibicuruzwa bisanzwe bya cork birajanjagurwa bikabikwa muburyo, bigatekwa mu ziko kuri 260 kugeza 316 ° C mumasaha 1 kugeza 1.5, hanyuma bigakonjeshwa mumatafari ya cork kugirango ubushyuhe buke. Irashobora kandi gukorwa nuburyo bwo gushyushya amavuta ashyushye.
ProductsIbicuruzwa bya cork. Ibice byiza bya cork bivangwa nifu nifata (nka resin, reberi) hanyuma bigashyirwa mubicuruzwa bya cork ciment, nkibikoresho byo hasi, imbaho ​​zerekana amajwi, imbaho ​​zitanga ubushyuhe, nibindi, bikoreshwa cyane mukirere, ubwato, imashini, kubaka, n'ibindi.
Ibicuruzwa bya rubber. Ikozwe mu ifu ya cork nkibikoresho fatizo nibirimo 70% bya reberi. Ifite compressible ya cork hamwe na elastique ya reberi. Ikoreshwa cyane nkibikoresho byo mu rwego rwo hejuru kandi biciriritse byumuvuduko wa static bifunga moteri, nibindi, kandi birashobora no gukoreshwa nka anti-seisimike, insulasiyo y amajwi, ibikoresho byo guterana, nibindi.
