Lesela la tlhaho la kork le sa thibeleng metsi a masela a li-cork bakeng sa lieta tsa basali le mekotla

Sefate sa softwood cork (se bitsoang cork oak linaheng tse ling) se thata ho ikamahanya le maemo a leholimo a batang le mocheso o phahameng. Ka kakaretso e hola merung ea lithabeng sebakeng se bophahamo ba limithara tse 400-2000 libakeng tse futhumetseng le tse futhumetseng. Ka har'a mefuta e fapaneng ea likhato tse 32 ho isa ho tse 35 tsa latitude e ka leboea, lisebelisoa tsa cork li ka fumanoa libakeng tse ngata tse lithaba tse kopanang le maemo a sebaka le boemo ba leholimo. Ka mohlala, Portugal, Spain, sebaka se ka boroa sa Fora, hammoho le Lithaba tsa Qinba naheng ea heso, ka boroa-bophirimela ho Henan, Algeria, joalo-joalo.
Portugal e maemong a pele lefatšeng ka ho romelloa kantle ho naha 'me e tsejoa e le "Kingdom of Cork" ka lebaka la boemo ba eona ba leholimo bo khethehileng ba Mediterranean, bo loketseng kholo ea lihlahisoa tse tala. Ka nako e ts'oanang, Portugal ke eona ea pele lefats'eng ka nts'etsopele ea lisebelisoa tsa koro, ho romela thepa e tala, le ts'ebetso e tebileng ea lihlahisoa. enngwe ya dinaha. Sehlahisoa sa softwood sa Algeria se maemong a holimo lefatšeng.
Lithaba tsa Qinba tse Shaanxi, naheng ea heso, le tsona li na le lisebelisoa tse ngata tsa likoti, tse etsang karolo e fetang 50% ea mehloli ea likoti tsa naha. Ka hona, Shaanxi e tsejoa e le "Cork Capital" indastering. Ho itšetlehile ka molemo ona oa lisebelisoa, bahlahisi ba bangata ba li-cork ba malapeng ba tsepamisitsoe haholo mona.
Cork e entsoe ka lisele tse ngata tse bataletseng tse hlophisitsoeng ka radially. Hangata sekoti sa sele se na le metsoako ea resin le tannin, 'me lisele li tlala moea. Ka hona, cork e atisa ho ba le mebala, e bobebe ebile e bonolo, e phutholohile, ha e kenelle, ha e amehe habonolo ke liphello tsa lik'hemik'hale, 'me ke mokhanni ea futsanehileng oa motlakase, mocheso le molumo. E entsoe ka lisele tse shoeleng tse mahlakoreng a 14 tse hlophisitsoeng ka radially ho tloha ho tse ling ka mokhoa oa hexagonal prism. Botenya ba sele ke 30 microns, 'me botenya ba lisele ke 1 ho 2 microns. Ho na le li-ducts lipakeng tsa lisele. Sebaka se pakeng tsa lisele tse peli tse haufi se entsoe ka lihlopha tse 5, tse peli tsa tsona ke tsa fibrous, tse lateloang ke tse peli tse nyenyane, le lera le lehong bohareng. Ho na le lisele tse fetang limilione tse 50 ka cubic centimeter e le 'ngoe. .
sebopeho
Sebopeho sena se etsa hore letlalo la cork le be le elasticity e ntle haholo, ho tiisa, ho thibela mocheso, ho thibela molumo, ho thibela motlakase le ho hanyetsa likhohlano. Ho phaella moo, ha e na chefo, ha e na monko, e nyenyane ka matla a khoheli a itseng, e bonolo ho ea ho ama, 'me ha e bonolo ho tšoara mollo. E ntse e se na lihlahisoa tse entsoeng ke Motho tse ka bapisoang le tsona. Mabapi le thepa ea lik'hemik'hale, motsoako oa ester o entsoeng ka mafura a 'maloa a hydroxy fatty acids le phenolic acid ke karolo ea sebopeho sa cork, e kopanetsoeng e bitsoang suberin.
Mofuta ona oa thepa o hanana le ho bola le tlhaselo ea lik'hemik'hale. Ka hona, ho phaella ho senya ho concentrated nitric acid, concentrated sulfuric acid, chlorine, iodine, joalo-joalo, ha e na phello ea lik'hemik'hale ho metsi, mafura, peterole, li-organic acid, letsoai, esters, joalo-joalo. lisebelisoa, joalo ka litšitiso tsa libotlolo, likarolo tsa ho kenya letsoho tsa lisebelisoa tsa sehatsetsi, li-lifebuoys, liphanele tsa ho koala molumo, jj.
Lihlahisoa
① Lihlahisoa tsa tlhaho tsa cork. Ka mor'a ho pheha, ho nolofatsa le ho omisa, ho khaola ka ho toba, ho hatisoa, ho fetoloa le mekhoa e meng ea ho etsa lihlahisoa tse phethiloeng tse kang li-plug, li-pads, mesebetsi ea matsoho, joalo-joalo.
② Lihlahisoa tsa cork tse halikiloeng. Lisebelisoa tse setseng tsa lihlahisoa tsa li-cork tsa tlhaho li hatelloa ebe li hatelloa ka libopeho, li behoa ka ontong ka 260 ho 316 ° C bakeng sa lihora tse 1 ho isa ho tse 1,5, ebe li pholile ka litene tsa likoti bakeng sa ho pata mocheso o tlaase. E ka boela ea etsoa ka mokhoa o matla oa ho futhumatsa mouoane.
③Lihlahisoa tsa likoti tse entsoeng ka samente. Likaroloana tse ntle tsa li-cork li kopantsoe le phofo le likhomaretsi (tse kang resin, rabara) ebe li hatelloa ka har'a lihlahisoa tsa likoti tse entsoeng ka samente, joalo ka li-veneers tsa fatše, liboto tsa ho kenya molumo, liboto tsa ho futhumatsa mocheso, joalo-joalo, tse sebelisoang haholo sebakeng sa sefofane, likepe, mechini. kaho, joalo-joalo.
④Lihlahisoa tsa rabara ea likoti. E entsoe ka phofo ea cork e le lisebelisoa tse tala le hoo e ka bang 70% ea lihlahisoa tsa rabara. E na le compressibility ea cork le elasticity ea rabara. Haholo-holo e sebelisoa e le lisebelisoa tsa boleng bo phahameng tse tlase le tse mahareng tsa khatello e tsitsitseng bakeng sa lienjine, joalo-joalo, hape e ka sebelisoa e le anti-seismic, insulation sound, lisebelisoa tsa likhohlano, jj.
