Isivikhi se-Monofilament: Imithambo yokuqonda kuzokufunda, ukulima, nokuhlola

Indlela Amashini Okukhishwa Kwemondofilamenti Ayisebenzisa Ukuproducwa Kwezinkinga Zokuhlola Ezinamandla

Amashini okukhishwa kwemondofilamenti ayiproducwa izinkinga zokuhlola ozikholwa kuzo abahloli bokuhlola nabahloli bokuhlola kwezinkinga ezinkulu. Ngokufaka amaphephelo amapolymer emuva kokukhishwa kwezinkinga zokuhlola, le misiyo iyakha izinkinga eziphambili nezinkinga eziphambili nezinkinga eziphambili. Izinkinga ezifika kufanele zibe nesivinini, ukuthintana, nokungabonakali kwezinkinga—lokhu okufune ukuphepha kwezinkinga kwezinkinga.

Ukulawulwa ngokunembile kobubanzi (0.150.35 mm) nokuqondiswa kwamangqamuzana ukuze kuqiniswe ukuqina nokungabonakali

Ukusebenza kwezingwegwe kuxhomeke ezicini ezimbili: ukufana kobubanzi nokuqondanisa kwama-molecule. Imishini yokuphotha i-monofilament igcina ububanzi phakathi kuka-0.15 mm no-0.35 mm ngokukhishwa okuphansi okungu-± 0.003 mmokuqinisekisa ukufakwa okubushelelezi nokungabonakali ngaphansi kwamanzi. Ngesikhathi esifanayo, ukucindezelwa okulawulwayo kwe-polymer encibilikisiwe kuqondisa amaketanga ayo e-molecule eduze kwe-axis ye-filament, okwandisa kakhulu amandla okudonsa ngaphandle kokwengeza umthamo. Ngokwesibonelo, i-monofilament engu-0.25 mm ingafinyelela amandla okuqhekeka angaphezu kuka-10 kgokuhlangabezana nezidingo zokudoba ezemidlalo kanye ne-pelagic trawling. Ukuqapha ububanzi besikhathi sangempela kwenza ukulungiswa kwenqubo ngokushesha, kuyilapho isigaba sokupholisa esilawulwayo sivala ukuqondanisa kwamangqamuzana ukuze kuvinjelwe izindawo ezibuthakathaka. Umphumela uba umugqa oqinile, oguquguqukayo futhi obonakalayo ngesikhathi esifanayo - obalulekile ekubhekiseni ezinhlotsheni eziqaphile.

Amathuluzi okuqondisa UV ase-PE/PA okuphinde kubhekwe ngokulingana nezindlela zokuqonda zika-FAO zokuthwala izilwane zomfula

Ukuqina ngaphansi kwelanga kuhlukanisa imigqa yokudoba esezingeni eliphakeme nabanye. Imishini ehamba phambili yokukhishwa kwe-monofilament isekela ukuhlanganiswa kwe-polyethylene (PE) ne-polyamide (PA) izingqimba kuhlanganisa ukuguquguquka kwe-PE nokumelana ne-PA. Uhlelo oluhlanganisiwe lokulinganisa i-UV stabilizer lubeka ama-photo stabilizer ngqo ku-polymer melt, okuqinisekisa ukuvikelwa okufanayo kulo lonke uhlangothi lwamafilament. Ukuhlolwa kubonisa ukuthi izintambo ezinjalo ezihlanganisiwe zigcina ama-95% amandla azo okudonsa okuqala ngemuva kwamahora angu-500 okuchayeka ku-UVehambisana ngokuphelele nemihlahlandlela ye-Food and Agriculture Organization (FAO) yezingcweti zokudoba ze-pelagic, ezifuna ukuqina ezindaweni ezinzima zasolwandle Lokhu kuzinza okufakiwe kwandisa isikhathi sokusebenza ezindaweni ezishisayo nasezintabeni eziphakeme, kuyilapho izici ezingezona ezidingekayo ezifana nezinhlamvu ezinemibala noma izindawo ezi-matte zinciphisa ukubonakala okubonakalayo. Kubasebenzisi bezimboni, umphumela uba ukuthi kuncishiswe imvamisa yokulungisa, kuncishiswe isikhathi sokuphumula, futhi kuthuthukiswe umnotho wokusebenza.

Ukuthuthukiswa kwe-Machine Yokuphuma Kwemithambo Yomthambo Oyisodwa Kuyaphakamisa Ukuthuthukiswa Kwemithambo Yomshado Wokusebenza Kwimfuyo

Amaphrofayili okuphuma okuhlanganiswa ngokwesibonelo esikhulu: ukubaluleka kwe-geometry yomthambo kuyahlinzeka ukugcina umkhawulo wokuload

Imisebenzi yezindlu zokuhlala zokufunda izinsizakalo ziyadinga imithambo yokuhlala eyisodwa ekhuluma ngokuphelele izinsizakalo ezinkulu ngaphandle kokusagela nokuvula. Imithambo yokuphuma yomthambo oyisodwa ene-die assemblies eziphelele zihlinzela amathambo ne-geometry esifanayo sesiphambili—kukhupha izindawo ezingenabuciko ezingavuliweyo kumithambo eyisodwa engavuliweyo. Lokhu kubaluleke kuzokwenza ukuload kubhekwe kuzo zonke izindawo zomthambo, kungakhuthaza izindawo zokuhlala ukuload okuphelele kwe-40 kg/m² ngaphandle kokuguqula. Ukuchaza kakhulu kwetempureteri yomthambo nokudraw ratio kuyahlinzela ukuthi izindlela zokuload zibe sifanayo ngasendleleni yonke yomthambo. Lokhu kuyisiphumo somthambo owahlala ngokuphelele futhi owasebenza ngasinye isihlanu—kukhupha izinqubo zokushintsha, izindlela zokusebenza, nokholi lokusebenza ngokuphelele kwebhizinisi yezinsizakalo.

Izinhlelo ezihlanganisiwe zokulinganisa i-UV stabilizer ezandisa isikhathi sokuphila ngaphandle iminyaka engu-5 + (ehambisana ne-ASTM D4329)

Ama-monofilament e-polyethylene ne-polyamide acekela phansi ngokushesha lapho ehlala isikhathi eside emisebe ye-UV ngaphandle uma eqiniswa kahle. Imishini ethuthukile yokukhishwa kwe-monofilament manje ifaka izinhlelo zokulinganisa i-UV stabilizer ezihlanganisa izithasiselo ngokulinganayo ku-polymer melt ngaphambi kokujikeleza, kuqinisekisa ukuthi ukuvikelwa kuyinto ebalulekile ku-filament, hhayi nje ukumboza komhlaba. Ngokwe-ASTM D4329 protocols yokusheshisa isimo sezulu, inetha lezolimo elilinganisiwe kahle ligcina okungenani u-80% wamandla alo okudonsa ngemuva kwamahora angu-5 000okuhumusha iminyaka emihlanu noma ngaphezulu yokusebenza kwangaphandle. Lokhu kuqina kwehlisa ngqo izindleko eziphelele zabomabhizinisi ngokuqeda ukushintshwa kwezimpahla, umsebenzi wokufaka kanye nokulahleka kwezitshalo okungahleliweokwenza ukufakwa kwe-trellising okuphezulu kube nokwenzeka ngokwezomnotho.

Ukucindezela okunembile kwe-monofilament kwezindaba zokuhlunga: Ukufana = Ukusebenza

Ukubekezelelana okuqinile kobubanzi (± 0.005 mm) okwenza kube nokusabalalisa okusobala kosayizi we-pore ezindwangu ezihlungiwe

Ezimweni zokuhlunga, ukusebenza kunqunywa ukuvumelana kosayizi we-pore futhi usayizi we-pore unqunywa yi-geometry ye-filament. Imishini yokukhishwa kwe-monofilament efinyelela i-± 0.005 mm diameter tolerance inikeza ukufana kwe-filament okudingekayo ekwakhiweni kwe-filter fabric ethembekile. Ngisho nokuguquguquka okuncane njengokuhluka okungu-0.01 mm kungadala ukuvuleka kwe-pore okungalindelekile, okuholela ekudluliseni izinhlayiya noma ukuvalwa ngaphambi kwesikhathi. Ngokulawula okungu-±0.005 mm, onjiniyela bangakwazi ukuklama ngokuzethemba amaphuzu okusika acwebile asezingeni le-micron (isb., 10 μm noma i-50 μm), okuqinisekisa ukusebenza okuphindaphindwayo kokuhlukanisa phakathi kwezinhlelo zokuhlunga uketshezi nomoya. Leli zinga lokucacisa libalulekile ezimbonini ezilawulwayo njengokudla neziphuzo kanye nokucutshungulwa kwamakhemikhali, lapho ikhwalithi yomkhiqizo engaguquguquki nempilo ende yokusebenza kuncike ekuziphatheni kokuhlunga okunganqunywa.

Amalayini weziflow eziningi, amalayini weziflow eziningi okukhulisa ukuproducwa kweziflow zemithili yamazibhambo

Izitshalo zokuhlanza amanzi kamasipala zidinga inani elikhulu lezinto zokuhlunga ukuze kuhlangatshezwane nemigomo yokuhlanza yansuku zonke. Imigqa yokucindezela imicu eminingi enamandla amakhulu ihlangabezana nale mfuneko ngokukhiqiza imicu eminingi ngesikhathi esisodwa kusuka ekhanda elilodwa lokufakhulisa kakhulu ukukhishwa kunamasistimu wendabuko we-single-filament. Ukuze kube nesikhungo esisebenza amalitha ayizigidi ezingu-50 ngosuku, isidingo sonyaka sendwangu yokuhlunga eshintshayo singadlula amamitha-skwele angu-100 000. Imigqa yesimanje ye-multifilament esebenza ngesivinini esingamamitha angu-50 kuya kwangu-100 ngomzuzu ingakhiqiza amakhilogremu angaphezu kuka-200 e-monofilament ngehora. Okubaluleke kakhulu, izilawuli eziphambili zedijithali zigcina ukubekezelelana kobubanzi obungu-±0.005 mm ngisho nasejubane eliphelelengokuqhubeka nokulawula ingcindezi yokuncibilika, izinga lokushisa, kanye nokudonsa amandla. Lokhu kuhlanganiswa kwesikali nokunemba kuqinisekisa amaketanga okuphakelayo azinzile ezakhiweni ezingukhiye zamanzi, kusekela ukuphepha kwamanzi emhlabeni wonke ngaphandle kokwenza ukuyekethisa ekusebenzeni noma ekuthembekeni.
