Inayiloni inomsebenzi okhethekile, ngakho-ke isetshenziswa kabanzi ezimotweni, imishini kagesi neyegesi, izakhiwo zemishini, imishini yezemidlalo, izindwangu, njll. Kodwa-ke, ukwenziwa kube lula kwezimoto, ukusebenza kahle kwemishini kagesi neyegesi, kanye nokukhanya kwemishini yemishini kuyashesha, isidingo kanye nezidingo zokusebenza kwenayiloni ziyanda kancane kancane. Ngakho-ke ukuguqulwa kwenayiloni kubonakala kubaluleke kakhulu.
Izinyathelo Zokuqapha Zokuguqulwa Kwe-Nylon
1. Ukusetha izinga lokushisa lemigqomo
(1) Ngenxa yokuthi i-nylon iyi-polymer ekristali, inendawo yokuncibilika esobala. Izinga lokushisa le-nylon emgqonyeni ngesikhathi sokujova lincike ekusebenzeni kwe-resin ngokwayo, umshini kanye nesimo somkhiqizo.
(2) Uma izinga lokushisa lezinto liphezulu kakhulu, lingabangela kalula ukushintsha kombala, ukuqhekeka kanye nemicu yesiliva plastic izingxenye, futhi uma izinga lokushisa lezinto liphansi kakhulu, kungenza izinto zibe nzima kakhulu futhi kungalimaza isikhunta kanye nesikulufu.
(3) Ngokuvamile, izinga lokushisa eliphansi lokuncibilika le-PA6 lingu-220℃, kanti ele-PA66 lingu-250℃. Ngenxa yokungazinzi kahle kokushisa kwe-nylon, akufaneleki ukuhlala emgqonyeni ekushiseni okuphezulu isikhathi eside ukuze kugwenywe ukushintsha kombala nokuphuzi kwezinto. Ngesikhathi esifanayo, ngoba i-nylon inoketshezi oluhle, igeleza ngokushesha ngemva kokuba izinga lokushisa lidlule iphuzu layo lokuncibilika.
2. Ukusetha izinga lokushisa lesikhunta
(1) Izinga lokushisa lesikhunta linomthelela othile ekukhanyeni nasekuncipheni kokubumba. Izinga lokushisa lesikhunta lisukela ku-80 kuya ku-120°C.
Khetha izinga lokushisa eliphezulu lesikhunta, ukwakheka kwekristalu okuphezulu, ukumelana nokuguguleka okwandisiwe, ubulukhuni, i-modulus enwebekayo, ukuncipha kokumuncwa kwamanzi, ukuncipha kokubumba komkhiqizo okwandisiwe, okufanele imikhiqizo ewugqinsi; khetha izinga lokushisa eliphansi lesikhunta, ukwakheka kwekristalu okuphansi, ukuqina okuhle, ukunwebeka. Izinga lokuncibilika eliphakeme liyancipha, lifanele imikhiqizo emincane enokubonakala okuhle.
(2) Uma ubukhulu bodonga bungaphezu kuka-3mm, kunconywa ukusebenzisa isikhunta esinokushisa okuphansi ku-20~40℃. Ukuze uthole izinto eziqiniswe ngengilazi, izinga lokushisa lesikhunta kufanele libe ngaphezu kuka-80°C.
(3) Ukulawulwa kwezinga lokushisa kwesikhunta lapho udonga lomkhiqizo luncane futhi kunzima ukwakheka noma ludinga ukwakheka okuqinile. Uma umkhiqizo udinga izinga elithile lokuguquguquka, kusetshenziswa ukulawulwa kwezinga lokushisa lamanzi abandayo.
3. Ubukhulu bodonga lomkhiqizo
Isilinganiso sobude bokugeleza kwe-nylon singu-150 kuya ku-200, kanti ubukhulu bodonga lomkhiqizo bungaphansi kuka-0.8mm, ngokuvamile bungu-1 kuya ku-3.2mm. Ngaphezu kwalokho, ukuncishiswa komkhiqizo kuhlobene nobukhulu bodonga lomkhiqizo. Uma ubukhulu bodonga bukhulu, kulapho ukuncishiswa kuba kukhulu khona.
4. Ukukhipha ugesi
Inani lokuchichima kwe-resin ye-nylon licishe libe ngu-0.03mm, ngakho-ke isikhala somoya kufanele silawulwe ngaphansi kuka-0.025.
5. Abagijimi namasango
Ububanzi bembobo yesango akufanele bube ngaphansi kuka-0.5t (ubukhulu bengxenye yepulasitiki). Ngamasango acwiliswayo, ububanzi besango obuncane kufanele bube ngu-0.75mm.
6. Uhla lokugcwalisa i-fiber yengilazi
Ngesikhathi senqubo yokubumba inayiloni, ukwehlisa izinga lokushisa lesikhunta, ukwandisa ingcindezi yomjovo, kanye nokwehlisa izinga lokushisa lezinto kuzonciphisa izinga lokuncibilika kwenayiloni ngezinga elithile, okwenza umkhiqizo ube lula kakhulu ekuguqukeni ngenxa yokucindezeleka kwangaphakathi okwandisiwe. Isibonelo, izinga lokuncibilika kwe-PA66 lingu-1.5% kuya ku-2%, kanti izinga lokuncibilika kwe-PA6 lingu-1% kuya ku-1.5%. Ngemva kokufaka izithasiselo zefayibha yengilazi, izinga lokuncibilika lingancishiswa libe cishe ngu-0.3%.
Okuhlangenwe nakho okusebenzayo kusitshela ukuthi uma kunezelwa i-fiber yengilazi eningi, kulapho ukuncibilika kokubumba kwe-resin ye-nylon kuncipha khona. Kodwa-ke, ukwengeza i-fiber yengilazi eningi kakhulu kuzobangela i-fiber entantayo ebusweni kanye nokuhambisana okungekuhle. Ngokuvamile, ukwengeza i-30% kunomphumela omuhle.
7. Ukusetshenziswa kwezinto ezigaywe kabusha
Kungcono ukungadluli izikhathi ezintathu ukuze ugweme ukushintsha kombala womkhiqizo noma ukwehla okukhulu kwezakhiwo zomzimba nezemishini. Inani lokusetshenziswa kufanele lilawulwe ngaphansi kuka-25%. Ukusetshenziswa ngokweqile kuzobangela ukuguquguquka kwezimo zenqubo. Ingxube yezinto ezisetshenziswe kabusha nezinto ezintsha kumele zomiswe.
8. Imiyalelo yokuphepha
Uma uqala i-resin ye-nylon, kufanele uqale uvule izinga lokushisa le-nozzle, bese ushisa i-barrel. Uma i-nozzle ivaliwe, ungabheki imbobo ye-nozzle ukuvimbela ukuncibilika ebhareleni ukuthi kungakhishwa ngokuzumayo ngenxa yokuqongelela kwengcindezi nokudala ingozi.
9.Ukusetshenziswa komenzeli wokukhululwa
Ukusebenzisa inani elincane le-ejenti yokukhulula ngezinye izikhathi kungathuthukisa futhi kususe amaphutha afana nama-bubble. I-ejenti yokukhulula imikhiqizo ye-nylon ingaba yi-zinc stearate, uwoyela omhlophe, njll., noma ingaxutshwa ibe yi-paste bese isetshenziswa. Inani kumele libe lincane futhi noma lisetshenziswa ukugwema amaphutha ebusweni bomkhiqizo. Isikulufu kufanele sikhishwe lapho umshini uvaliwe ukuvimbela isikulufu ukuthi singaphuki ngesikhathi sokukhiqiza okulandelayo.
10. Ngemuva kokucubungula
(1) Ukwelashwa ngokushisa kuyadingeka ngemva kokuba umkhiqizo usubunjiwe.
Izindlela ezivame ukusetshenziswa: Ezintweni ezibilayo kakhulu ezifana namafutha amaminerali, i-glycerin, kanye ne-paraffin ewuketshezi, izinga lokushisa lokwelapha ukushisa kufanele libe ngu-10 kuya ku-20°C ngaphezu kwezinga lokushisa lokusetshenziswa. Isikhathi sokwelapha siyahlukahluka kuye ngokuthi umkhiqizo uqine kangakanani. Ubukhulu buyimizuzu eyi-10 kuya kweyi-15 uma ubukhulu bungaphansi kuka-3 mm, kanti ubukhulu buyimizuzu emi-3 kuya kwengama-20. Isikhathi esingu-6 mm siyimizuzu eyi-15 kuya kwengama-30. Imikhiqizo ephathwe ngokushisa kufanele ipholiswe kancane kancane ibe yizinga lokushisa legumbi ukuvimbela ukuvuselelwa kokucindezeleka emikhiqizweni okubangelwa ukupholisa okungazelelwe. (2) Ukwelashwa kokulawula umswakama kufanele kwenziwe ngemva kokuba umkhiqizo usukhiwe.
Ukwelashwa kokulungisa umswakama kwenziwa kakhulu emikhiqizweni enomswakama ophezulu endaweni ezungezile. Kunezindlela ezimbili: enye indlela yokulungisa umswakama emanzini abilayo; enye indlela yokulungisa umswakama ngesisombululo samanzi se-potassium acetate (isilinganiso se-potassium acetate namanzi singu-1.25:1, iphuzu lokubila lingu-121°C).
Indlela yokulawula umswakama wamanzi abilayo ilula, inqobo nje uma umkhiqizo ubekwe endaweni enomswakama ongu-65% ukuze kufezwe ukumuncwa komswakama olinganayo, kodwa kuthatha isikhathi eside, kuyilapho indlela yokulawula umswakama wesisombululo samanzi se-potassium acetate idinga i-acetic acid ekushiseni kokucubungula okungu-80 kuya ku-100°C Indlela yokulawula umswakama wesisombululo samanzi se-potassium aqueous, isikhathi sokucubungula sincike kakhulu ekujikeni kodonga lomkhiqizo, cishe amahora ama-2 lapho ukujiya kodonga kungu-1.5 mm, cishe amahora ayi-8 lapho ukujiya kodonga kungu-3 mm, kanye namahora ayi-16 kuya kwangu-18 lapho ukujiya kodonga kungu-6 mm.
