I-Polyamide (PA) i-polymer equkethe amaqembu e-amide aphindaphindiwe ochungechungeni oluyinhloko.Evame ukubizwa ngeNylon, i-PA ingenye yamapulasitiki onjiniyela athuthukiswa futhi asetshenziswa kakhulu.Kulesi sihloko namuhla,Qingdao Sainuokuzokuthatha wazi amaphuzu ayishumi abalulekile wokuguqulwa kwenayiloni.

pp waxngoba inayiloni eshintshiwe

Izakhiwo ezikhethekile zenayiloni ziyenza isetshenziswe kabanzi ezimotweni, imishini kagesi nekagesi, ukwakheka kwemishini, imishini yezemidlalo, izindwangu nokunye.Kodwa-ke, ngokushintshwa okuncane kwezimoto, ukusebenza okuphezulu kwemishini kagesi nekagesi, kanye nokusheshisa inqubo yemishini engasindi yemishini, isidingo senayiloni nokusebenza kwayo sikhula kancane kancane.Ngakho-ke ukuguqulwa kwenayiloni kubaluleke kakhulu.
Izinto ezidinga ukunakwa ekuguqulweni kwenayiloni
1. Ukusetha izinga lokushisa lomgqomo
(1) Ngenxa yokuthi inayiloni iyi-polymer ecwebezelayo, indawo yayo yokuncibilika isobala.Izinga lokushisa lomphongolo we-nayiloni resin ekubunjweni komjovo lihlobene nezakhiwo ze-resin, izinto zokusebenza kanye nokuma komkhiqizo.
(2) Izinga lokushisa eliphakeme kakhulu lempahla kulula ukubangela ukushintsha kombala, i-brittleness kanye nocingo olusiliva, kuyilapho izinga lokushisa eliphansi kakhulu lezinto ezibonakalayo zenza into ibe nzima futhi ingalimaza i-die and screw.
(3) Ngokuvamile, izinga lokushisa elincibilikayo eliphansi kakhulu le-PA6 lingama-220 ℃ kanye ne-PA66 lingu-250 ℃.Ngenxa yokuqina okushisa okumpofu kwe-nylon, akufanelekile ukuhlala emgqonyeni isikhathi eside ekushiseni okuphezulu, ukuze kungabangeli ukuguquguquka nokuphuzi kwezinto.Ngesikhathi esifanayo, ngenxa yobumanzi obuhle benayiloni, igeleza ngokushesha lapho izinga lokushisa lidlula indawo yayo yokuncibilika.
2. Ukulungiselelwa kwezinga lokushisa kwesikhunta
(1) Izinga lokushisa lesikhunta linethonya elithile ekucwebezeleni nasekuncipheni kokubumba.Izinga lokushisa lesikhunta lisukela ku-80 ℃ kuya ku-120 ℃.Izinga lokushisa eliphakeme lesikhunta, i-crystallinity ephezulu, ukwanda kokumelana nokuguga, ubulukhuni, i-modulus yokunwebeka, ukwehla kokumuncwa kwamanzi, ukuncipha kokubumba okukhulayo, okulungele imikhiqizo ewugqinsi;
(2) Uma ukushuba kodonga kungaphezu kuka-3 mm, kutuswa ukusebenzisa isikhunta sokushisa esiphansi esino-20 ~ 40 ℃.Ngezinto eziqiniswe ngengilazi, izinga lokushisa lesikhunta kufanele libe ngaphezu kuka-80 ℃.

3. Ukuqina kwezindonga zemikhiqizo
Isilinganiso sobude bokugeleza benayiloni singu-150-200, ubukhulu bodonga lomkhiqizo abukho ngaphansi kuka-0.8mm, ngokuvamile obungu-1-3.2mm, futhi ukushwabana komkhiqizo kuhlobene nogqinsi lodonga lomkhiqizo.Lapho ubukhulu bodonga buba bukhulu, kukhulu ukuncipha.
4. Ukukhathala
Inani elichichimayo leresin enayiloni licishe libe ngu-0.03mm, ngakho-ke imbobo yokukhipha umoya kufanele ilawulwe ngaphansi kuka-0.025.
5. Umgijimi nesango
I-diameter yembobo yesango akufanele ibe ngaphansi kuka-0.5T (t ukujiya kwengxenye yepulasitiki).Ngesango elingaphansi kwamanzi, ububanzi obuncane besango kufanele bube ngu-0.75mm.
6. Ibanga lokugcwalisa i-fiber yengilazi
Enqubweni yokubumba inayiloni, ukunciphisa izinga lokushisa kwesikhunta, ukwandisa ingcindezi yomjovo kanye nokunciphisa izinga lokushisa lezinto ezibonakalayo kuzonciphisa ukushwabana kwenayiloni ngezinga elithile, kwandise ukucindezeleka kwangaphakathi komkhiqizo futhi kwenze kube lula ukonakala.Isibonelo, ukushwabana kwe-PA66 kungu-1.5% ～ 2%, ukushwabana kwe-PA6 kungu-1% ～ 1.5%, futhi ukushwabana kungancishiswa kube cishe ku-0.3% ngemuva kokwengeza isithako se-fiber yengilazi.
Okuhlangenwe nakho okungokoqobo kusitshela ukuthi uma kunezelwa imicu yengilazi eyengeziwe, kuba kuncane ukushwabana okubunjwayo kwenhlaka yenayiloni.Kodwa-ke, uma i-fiber yengilazi yengezwe kakhulu, izobangela i-fiber entantayo phezulu, ukungahambisani kahle neminye imiphumela.Ngokuvamile, umphumela wokwengeza u-30% muhle uma kuqhathaniswa.
7. Ukusetshenziswa kwezinto ezigaywe kabusha
Kungcono ukuthi ungeqi izikhathi ezintathu ukuze ugweme ukuguquguquka kombala noma ukwehla okubukhali kwezakhiwo zomzimba nemishini.Inani lesicelo kufanele lilawulwe libe ngaphansi kwama-25%, kakhulu lizodala ukushintshashintsha kwezimo zenqubo, futhi ingxube yezinto ezigaywe kabusha nezinto ezintsha kumele zomiswe.
8. Iziyalezo zokuphepha
Lapho inhlaka yenayiloni iqalwa, izinga lokushisa lembobo kufanele livulwe kuqala, bese izinga lokushisa lishiswe emgqonyeni wokuphakela.Uma umlomo wombhobho uvinjiwe, ungalokothi ubhekane nembobo yesifutho, ukuze uvimbele ukuphuma kungazelelwe kokuncibilika emgqonyeni wokuphakela ngenxa yokunqwabelana kwengcindezi, okungase kubangele ingozi.

9. Ukusetshenziswa kwe-ejenti yokukhulula
Ukusetshenziswa kwenani elincane le-ejenti yokukhulula isikhunta kwesinye isikhathi kungathuthukisa futhi kuqede i-bubble nezinye iziphambeko.I-ejenti yokukhishwa kwemikhiqizo yenayiloni ingaba yi-zinc stearate namafutha amhlophe, noma ixutshwe kunamathisele.Inani le-ejenti yokukhulula kufanele libe lincane futhi lifane ukuze kugwenywe ukukhubazeka kwendawo.Isikulufu kufanele sithululwe lapho umshini uvalwa ukuze kuvinjelwe isikulufu ekuphukeni phakathi nokukhiqizwa okulandelayo.

10. Thumela ukwelashwa
(1) Imikhiqizo kufanele ilashwe ngokushisa ngemva kokwakhiwa
Izindlela ezivamile kuwoyela wamaminerali, i-glycerin, upharafini owuketshezi kanye nolunye uketshezi lwamaphuzu aphezulu abilayo, izinga lokushisa lokwelashwa kokushisa kufanele libe ngu-10 ~ 20 ℃ ngaphezu kwezinga lokushisa lokusetshenziswa, futhi isikhathi sokwelashwa sincike ekugqineni kodonga lomkhiqizo.Ugqinsi olungaphansi kuka-3 mm luyi-10 ~ 15 min, ukujiya luyi-3 ~ 6 mm, futhi isikhathi siyi-15 ~ 30 min.umkhiqizo emva kokwelashwa okushisa kufanele upholiswe kancane kancane ekamelweni lokushisa, ukuze uvimbele ukupholisa okungazelelwe ekubangeleni ukukhiqizwa kabusha kokucindezeleka emkhiqizweni.
(2) Imikhiqizo kufanele iphathwe ngokulawula umswakama ngemva kokubunjwa
Ukulawula ukuswakama kusetshenziselwa ikakhulukazi imikhiqizo enomswakama ophezulu.Kunezindlela ezimbili: eyodwa ukubilisa umswakama wamanzi;Enye inqubo emanzi ye-potassium acetate aqueous solution (isilinganiso se-potassium acetate emanzini si-1.25:1, iphoyinti elibilayo 121 ℃).
Amanzi abilayo alula, inqobo nje uma umkhiqizo ubekwe endaweni enomswakama ongu-65%, ukuze ukwazi ukufinyelela ukumuncwa komswakama olinganayo, kodwa isikhathi side.Izinga lokushisa lokwelapha le-potassium acetate isixazululo samanzi ngu-80 ~ 100 ℃, futhi isikhathi sokwelashwa sincike kakhulu ekugqileni kodonga lomkhiqizo, lapho ukushuba kodonga kungu-1.5mm, cishe 2h, 3mm, 8h, 6mm, 16 ~ 18h.
