Umthi Hevea and "ubisi irabha" yayo

Omnye izityalo ezimangalisayo Mother Nature ezalise ilizwe lethu, i Hevea emthini. Yintoni esisodwa, yintoni phezulu kwakhe ukusetyenziswa womntu, yaye Ikhangeleka njani ngayo? Kodwa nantsi eyona nyaniso.

Inkangeleko kunye neempawu Plants

Hevea (irabha tree) - isityalo tropical ukuba ifumaneka Indonesia, Malaysia kunye Umzantsi Melika. ngokhethekileyo yokuba xa liqatywe le uthinte edlala i incindi njengamasi emhlophe, esifana incindi milkweed aqhelekileyo kunye edandelion. mass Frozen iye isetyenziswe lokuvelisa izinto zekhaya ezahlukeneyo, kubandakanywa iibhola imidlalo isiko yi amaNdiya.

Hevea umthi ngokwayo kokwabo sodidi kwemithi ebomvu, amandla eyahlukileyo kangaka engaqhelekanga, nobulukhuni kweenkuni kwakhona lula ukuqhuba. Amanqaku zalo ukumelana ukubola; ngoko ke ixesha elide kakhulu yaye ezintle. Kodwa ixabiso iphambili esi sityalo, ndimkhathalela iimitha ukuya ku mahlanu ephezulu isiselo wayo.

ubisi irabha

Leyo yindlela abemi ekweleenjiko kuthiwa incindi, enika isityalo Hevea. Latex (ijusi efanayo ngokwenzululwazi) kuveliswe kude umthi ngamnye. Kwindawo yokuqala kufuneka ufikelele kwiminyaka yobudala engama-elishumi okanye elinambini. Yaye zijongisise kwiminyaka imithi zerabha kunceda kuphela ukuphakama kwayo sangqa ibhuthi, njengoko amakhonkco osikiweyo kunye nemvakalo ngayo. "Abadala" kungathathwa kubude izityalo oziimitha ezi-24 kanye ububanzi ngeesentimitha eziyi-75. Ukuba luthathe irabha kumthi elinye kunokuba ukuya kwiminyaka engamashumi amathathu, ngoko ke uyagawulwa, indawo kunye nezityalo abaselula. Kodwa ingakumbi geveyu wabeka: kwindawo efumileyo yaye begcakamele imbewu zayo ezinkulu ezifana chestnuts, ngokwabo zihlume. Ngoko ke, abasebenzi bade ukuba ziyucwe yimimango izityalo abaselula, ngoko ke musa ukuba kwihlathi.

Kubalulekile ukuphawula ukuba Latex itsalwa kuphela emithini ngerabha. iimpawu ezifanayo juice zamafu yezinye zamakhiwane, kodwa isityalo eBrazil - kakhulu nemveliso, kunye irabha kuyo na ezikumgangatho ophezulu. Yiloo nto Hevea umthi bazalisa zonke elutyalweni lwehlabathi loo.

Indlela ukuqokelela irabha?

Ijusi ukuba licatshulwa imithi irabha, ikwesi, ndawonye irabha, amanzi, iiprotheni, nentlaka, iswekile, kunye nothuthu. Ngoko ke, emva kokuba nokuqokelela ulwelo kwakuwo "acudisiweyo 'emanzini. Le irabha crude ekuthiwa, nto leyo kamva yaguqulwa yaba material yeemveliso ezahlukeneyo irabha.

Ntsasa nganye, le Hevea umthi phantsi kwimisebenzi efana: yomqeshi ye ngemela liqatywe okhethekileyo, enzulu izidanga. Ngaphantsi kokuba isikhongozeli apha zokuqokelela juice ubisi - udongwe okanye porcelain iikomityi ezincinane. Ngosuku ngalunye kwaye konke oku kuqokelelwa malunga namakhulu amabini grams yesiselo. Emva kwesidlo sasemini, yokusebenza bypasses irabha elutyalweni kwaye zidibana lonke umxholo ikani. Kwaye ngoko "isivuno" ithunyelwa efektri kuqhutywe.

juice Hevea yemboni

Yintoni na enawe kwincindi eqokelelwe umthi engaqhelekanga? Its filter, acetic acid kunye obuthelwe sheets bhaka enkulu. Kukho intabalala ubunjwe ze eqina. Ke ingubo emhlophe waqengqela ngokusebenzisa rolls zentsimbi kufuze kwaye zonekwe. Isigaba sokugcina - ukutshaya, ekuthe irabha uba umbala voskoprozrachny kunye nokhuselo iimbovane abalambileyo.

Ubomi imithi enye

Kubalulekile ukuphawula ukuba umthi omdala irabha ubonakala embi kakhulu. Its ngokuba yonke imihla iminyaka elishumi elinesihlanu ukuya kumashumi amabini bonakalisa amanxeba. Le kuqweqwe lugubungela ngokupheleleyo buti ukusuka kwisiseko ukuya akhule (ngaphezu juice yokuqokelela lingavumi). nomkhombe nganye entsha lingaphantsi lilonke yangaphambili inxalenye uthinte, kwaye xa elinye icala umthi igutyungelwe ngeenotshi, koko udlulele kwenye. Xa kuya kubakho ndawo zingabanjwanga, umsebenzi ubuyela phambi komboko amanxeba liqiniswe kukuqulungana "amanxeba". Zonke ngenxa yomphefumlo umthi rubber emzimbeni wakhe zidipozithwe malunga namawaka alishumi cuts, apho kuqokelela ukuya iitoni ezimbini ngerabha.

Kufuneka kuqatshelwe ukuba imixholo ehlathini irabha - kukulungele kakhulu. Emakethe zomhlaba Ndiziva izinto ekrwada kudla malunga ezintandathu zeedollar, yaye omnye umthi kunganika unyaka yejusi ka 40-50 zeerandi, ngaphandle kokufuna iindleko ezongezelelekileyo. Yiloo nto kwi-Malay Archipelago emasimini onke ezikhoyo somhlaba ukhula Hevea. Umthi ifoto ukuba thaca kweli nqaku zithathwa isipho woothixo, yaye iyinxalenye ebalulekileyo kwezoqoqosho.

wamagama

Kubalulekile ukuphawula ukuba namhlanje basoloko sisebenzisa iinkuni neenkuni rubber zefanitshala, izakhelo, izincedisi ikhitshi, umgangatho. ukusika iibhodi ingakumbi elungileyo kuyo, ngenxa yokuba izikhohlakali zingamoyiki ukufunxa ukufuma. A Umbala Hevea ezizodwa evumela izinto kuphela kunye nokuphumeza ubungqola kakhulu ethelekelelwayo of nabayili. Nantsi ke, umthi ekhethekileyo evela Yehlabathi Elitsha, nto leyo ethe yenza ubomi bomntu bekhululekile ngakumbi. Kwaye ngoku kowona msebenzi Homo sapiens ukulondoloza le sityalo, kuba ungalahleka kuyo ebusweni bomhlaba ngenxa amandla ukusetyenziswa kwayo.
