Mvura isingadziviriri yekork jira inonamira machira echikadzi shangu nemabhegi

The softwood cork tree (inonzi cork oak kune dzimwe nyika) yakaoma kuenderana nekutonhora kwakanyanya uye kutonhora kwemamiriro okunze. Inowanzokura mumasango emakomo pahupamhi hwe400-2000 metres munzvimbo dzinopisa uye dzakadzikama. Mukati mehupamhi hwe32 kusvika 35 madhigirii kuchamhembe latitude, zviwanikwa zvekork zvinogona kuwanikwa munzvimbo zhinji dzemakomo dzinosangana nemamiriro ekunze uye ekunze. Semuenzaniso, Portugal, Spain, nzvimbo yekumaodzanyemba kweFrance, pamwe neMakomo eQinba munyika yangu, kumaodzanyemba kwakadziva kumadokero kweHenan, Algeria, nezvimwewo.

Nokudaro, cork inowanzova nemavara, yakareruka uye yakapfava, yakanyunguduka, isingapindiki, isingasviki nemigumisiro yemakemikari, uye inoshaya conductor yemagetsi, kupisa uye inzwi. Iyo inoumbwa negumi nemana-mativi maseru akafa akarongwa radially kubva kune mumwe mune hexagonal prism pateni. Yakajairika sero dhayamita i30 microns uye sero ukobvu i1 kusvika 2 microns. Kune ma ducts pakati pemasero. Nzvimbo iri pakati pemaseru maviri akatarisana inoumbwa nezvikamu zvishanu, zviviri zvacho zvine fibrous, zvichiteverwa nezvikamu zviviri zvakaiswa pasi, uye danda rehuni pakati. Kune masero anodarika mamiriyoni makumi mashanu pa 1 cubic centimita. .

Ichi chimiro chinoita kuti ganda rekork rive rakanaka kwazvo elasticity, kuvhara, kupisa kwekupisa, kuvharidzira inzwi, kuvharwa kwemagetsi uye kusagadzikana kwekupokana. Pamusoro pezvo, haina chepfu, haina kunhuwa, idiki mune yakananga giravhiti, yakapfava pakubata, uye haisi nyore kubata moto. Haisati ichine zvigadzirwa zvakagadzirwa neMunhu zvinofananidzwa. Panyaya yemakemikari zvivakwa, musanganiswa we ester wakaumbwa neanoverengeka hydroxy fatty acids uye phenolic acids inhengo yehunhu yekork, pamwe chete inonzi suberin.
Rudzi urwu rwezvinhu runoshingirira mukuora uye kurwisa kwemakemikari. Nokudaro, kunze kwekuve inoparadza kune yakasanganiswa nitric acid, yakanyanyisa sulfuric acid, chlorine, iodine, nezvimwewo, haina chemikemikari pamvura, girisi, peturu, organic acids, munyu, esters, nezvimwewo. mashandisirwo, senge zvivhariso zvemabhodhoro, zvidzitiro zvekudzivirira zvemidziyo yefiriji, lifebuoys, mapaneru ekuvharisa ruzha, nezvimwe.
