Nkhondo pakati pa Marine life ndi "ghost network" siimaima.
Mukuyenda m’mphepete mwa nyanja, mumatha kuona maukonde osodza otayidwa mkati mwa masitepe ochepa, omwe ndi ozungulira komanso opiringizika. Pang'onopang'ono chokani ndi dzanja, sindimayembekezera kungowona nsonga ya madzi oundana.
Amachokera pansi pa nyanja ndipo amakokoloka m'mphepete mwa nyanja pamafunde amphamvu. N'zovuta kulingalira kuchuluka kwa "maukonde" amenewa omwe amapezeka munyanja yakuya. Ndizovuta kukhulupirira kuti ndi angati zamoyo zam'madzi zomwe zingadye molakwika ndikuzunguliridwa ndi ukonde wa imfa.
Kodi pali ukonde woyenera kwambiri waulimi wapanyanja womwe suipitsa chilengedwe?
Inde, Hebei Hnegtuo Machinery Equipment CO.,LTD adapanga zida zatsopano zophera nsomba za poliyesitala,HGTO ONANI ZOYENERA KULIMA NSOMBA ZOPHUNZITSIRA KIKKO UKWATA KUPANGA MACHINE.
Choyamba, tiyeni tiyankhule za mawonekedwe a ukonde wa polyester:
Poyerekeza ndi chikhalidwe polyethylene zinthu zopangidwa ndi khola madzi akuya, ali ubwino kulemera kuwala, madzi fluidity wabwino, wamphamvu mphepo kukana, zovuta kukwera zamoyo za m'nyanja, mphamvu mkulu, zovuta kuthyoka, yosalala pamwamba, asidi ndi alkali kukana. , kukana kwa radiation ya UV, kukana kukalamba kwanyengo, kosavuta kuyeretsa, kupulumutsa nthawi, kukana dzimbiri ndi zina zotero.
Kulemera kopepuka: kosavuta kugwira ntchito panyanja.
Good madzi kuyenda: kwambiri kusintha madzi kuyenda, kuti kusintha mpweya zili khola, akhoza kusintha liwiro la nsomba m'badwo, kuchepetsa kuchuluka kwa matenda nsomba, kotero kuti khalidwe la nsomba wakhala kulimbikitsa.
Kukana kwamphamvu kwamphepo: kapangidwe kake kapadera kachitsulo kachitsulo kamakhala mu mphamvu zamphamvu zam'nyanja zimatha kukhalabe ndi mawonekedwe oyambira pafupifupi osasinthika.
Sikophweka kukwera: polyester yoyera (PET) monofilament pamwamba yosalala, osati mayamwidwe amadzi ndi kuyamwa kwa chinyezi. Malo osalala amachepetsa kwambiri kuphatikizika kwa zamoyo za m'madzi, ndipo kumafuna ntchito yoyeretsa yocheperako kangapo kuposa zovala zachikhalidwe za ukonde.
Mphamvu yayikulu, yosavuta kuthyoledwa: ukonde wa polyester deep sea aquaculture ukonde chifukwa cha kapangidwe kake kazitsulo kakang'ono kamatha kukana kuukira kwa nyama zolusa, zimangofunika ukonde umodzi wokha sufunika kuwonjezera ukonde woteteza, ngakhale gululi litawonongeka silingatero. kukhala kosavuta kukokedwa, akhoza mogwira kuteteza chiopsezo aquaculture nsomba kuthawa.
Acid ndi alkali, kukana dzimbiri: angagwiritsidwe ntchito ku chilengedwe chakuya nyanja, m'mayiko akunja, ntchito zakuya nyanja khola lalembedwa, wakhala zaka zoposa 35.
Kukana kwa radiation ya UV, kukana kwanyengo: Zida za polyester zili ndi mbiri yopitilira zaka 60 zogwiritsidwa ntchito kumunda.
