umnatha wokuloba,umnatha wokuloba.Ukuloba izixhobo ezizodwa zokwakha izixhobo.Ngaphezulu kwe-99% icutshungulwa kwimicu yokwenziwa.Kukho ubukhulu becala inayiloni 6 okanye i-nylon monofilament elungisiweyo, i-multifilament okanye i-multi-monofilament, kunye nemicu efana ne-polyethylene, i-polyester, kunye ne-polyvinylidene chloride nayo ingasetyenziswa.Iminatha esetyenziswa kwimveliso yokuloba ibandakanya inethi zokuloba, ipurse seine net, i-cast net, i-fixed nets.Iitrawl kunye ne-purse seines yiminatha enzima esetyenziswa kushishino lokuloba elwandle.Ubungakanani be-mesh bu-2.5 ukuya ku-5 cm, ububanzi bentambo yomnatha bu malunga ne-2 mm, kwaye ubunzima bomnatha buziitoni ezininzi okanye iitoni ezininzi.Ngokuqhelekileyo, ipere ye-tugboats isetyenziselwa ukutsala kunye nokuleqa iqela lokuloba ngokwahlukileyo, okanye isikhephe esilula sisetyenziselwa ukurhwebesha intlanzi kwiqela kunye nokulirhangqa.Iminatha yokuphosa yiminatha esebenza lula yokuloba emilanjeni nasemachibini.Ubungakanani be-mesh bu-1 ukuya kwi-3 cm, ububanzi bentambo yomnatha bu malunga ne-0.8 mm, kunye nobunzima beekhilogram ezininzi.Iminatha ezinzileyo kunye neekheji ziyiminatha ezinzileyo yenkcubeko eyenziweyo kumachibi, amadama okanye amatheku.Ubungakanani kunye neenkcukacha ziyahluka ngokweentlanzi eziphakanyiswayo, kwaye iintlanzi zigcinwa kwindawo ethile yamanzi ukuze zingaphumi.Iminatha yokuloba ineenjongo ezininzi.
Ngophuhliso lokuloba, izinto zokuloba kunye nokuzingela azikho iintlanzi kuphela, kodwa izixhobo zokuloba nazo zihamba phambili kunye namaxesha.Iminatha yokuloba yahlulahlulwe ngokwemisebenzi yaba yiminatha yokurhuqa (inethi zokuloba), iminatha ye-purse seine, ukwakhiwa komnatha kunye nokubeka umnatha.
Iminatha yokuloba esetyenziswa ngokuqhelekileyo ihlelwa ngolu hlobo:tsala iminatha, iminatha yokukhukuliseka,uncamathele iminatha.Kufuneka ibe nokungafihli okuphezulu (inxalenye yenayiloni yenayiloni) kunye namandla, ukumelana nempembelelo entle, ukunganyangeki kwe-abrasion, ukuzinza kwe-mesh dimensional kunye nokuthamba, kunye nobude obufanelekileyo ngexesha lekhefu (22% ukuya kwi-25%).Icutshungulwa yi-monofilament, i-multifilament intambo ephothiweyo (ene-knotted net) okanye i-monofilament warp weaving (i-raschel, eyeye-non-knotted net), unyango olulodwa lobushushu (i-nodule ehleliweyo), ukudaya kunye nonyango lobushushu besibini (ubungakanani obulungisiweyo be-mesh).Izinto ezisetyenziswayo zokuluka iminatha yokuloba ziyi-15-36 imisonto yenayiloni ye-210-denier, i-polyester multifilament kunye ne-ethylene monofilament enobubanzi obuyi-0.8-1.2 mm.Iindlela zokuluka ziquka ukuqhina, ukujija kunye nokunitha kwe-warp.
Zeziphi ezonatha zisetyenziswa kakhulu?
1. Iminatha yokuloba zizixhobo zokuvelisa zabalobi, ezinokuthi zisetyenziswe ukubambisa iintlanzi, i-shrimps kunye noononkala phantsi kwamanzi.
2. Iminatha yokuloba isenokusetyenziswa njengesixhobo sokukhusela, njengeminatha yokuthintela ookrebe, enokusetyenziswa ukukhusela iintlanzi ezinkulu eziyingozi njengookrebe.
3. Iminatha yokuloba inokwenza umphumo wobugcisa obubonakalayo.
