Nsalu Zogwirizana ndi Zachilengedwe

Tanthauzo la nsalu zokometsera zachilengedwe ndi lalikulu kwambiri, lomwe limakhalanso chifukwa cha chilengedwe chonse cha tanthawuzo la nsalu.Nthawi zambiri, nsalu zokometsera zachilengedwe zitha kuonedwa ngati zotsika kaboni, zopulumutsa mphamvu, mwachilengedwe zopanda zinthu zovulaza, zowongoka zachilengedwe komanso zogwiritsidwa ntchitonso.

Nsalu zoteteza zachilengedwe zitha kugawidwa m'magulu awiri: nsalu zoteteza zachilengedwe komanso nsalu zoteteza zachilengedwe.

Nsalu zokhala ndi chilengedwe nthawi zambiri zimakhala ndi nsalu za RPET, thonje lachilengedwe, thonje lamitundu, nsungwi, ulusi wa soya, ulusi wa hemp, modal, ubweya wa organic, log Tencel ndi nsalu zina.

Industrial zoteteza zachilengedwe nsalu wapangidwa ndi inorganic zinthu sanali zitsulo ndi zipangizo zitsulo monga PVC, poliyesitala CHIKWANGWANI, galasi CHIKWANGWANI, etc., amene angathe kukwaniritsa zotsatira za chitetezo cha chilengedwe, kuteteza mphamvu ndi recy gwiritsitsani ntchito zothandiza.

Pakali pano, nsalu yatsopano yoteteza zachilengedwe ndi nsalu ya RPET, yomwe ndi zinthu zobiriwira zobwezerezedwanso zomwe zimalimbikitsidwa padziko lonse lapansi, ndipo zakhala zikugwiritsidwa ntchito kwambiri pazinthu za nsalu.

Nsalu ya RPET, nsalu ya RPET ndi mtundu watsopano wa nsalu zotetezera zachilengedwe, dzina lathunthu lopangidwanso ndi nsalu za PET (nsalu ya polyester yowonjezeredwa).Zopangira zake ndi ulusi wa RPET wopangidwa kuchokera ku mabotolo obwezerezedwanso a Baote kudzera pakuwunika kwabwino, kupatukana, kudula, kupota, kuziziritsa ndi kusonkhanitsa silika.Nsalu yopangidwa kuchokera ku RPET ndi RPET pamwamba, yomwe imadziwika kuti coke botolo loteteza chilengedwe.Nsaluyo imatha kubwezeretsedwanso, yomwe ingapulumutse mphamvu, kugwiritsa ntchito mafuta komanso kuchepetsa mpweya wa carbon dioxide.Paundi iliyonse ya nsalu zobwezerezedwanso za RPET imatha kupulumutsa mphamvu 61000 BTU, yofanana ndi mapaundi 21 a carbon dioxide.Pambuyo popaka utoto woteteza zachilengedwe, zokutira ndi kusungitsa kalendala, nsaluyo imathanso kuyesa mayeso a MTL, SGS, ake ndi miyezo ina yapadziko lonse lapansi.Pakati pawo, phthalate (6p), formaldehyde, lead (PB), polycyclic onunkhira hydrocarbons, nonylphene ndi zizindikiro zina zachilengedwe zafika pamiyezo yaposachedwa kwambiri ya ku Europe komanso miyezo yaposachedwa yachilengedwe yaku America.Kukwezeleza ndi kugwiritsa ntchito nsalu zokometsera zachilengedwe kumathandizira kwambiri kuchepetsa kugwiritsiridwa ntchito kwa mphamvu ya petroleum ndi kuipitsidwa kwa mpweya wa kaboni padziko lonse lapansi.

Nsalu zathu zachikwama zotumizidwa ndi zomangira zonse zitha kufikira Miyezo iyi ya Zachilengedwe kuti ikhutiritse makasitomala padziko lonse lapansi.
