I-30% ye-fiber yengilazi eqiniswe ukuguqulwa kwe-PA6
I-30% ye-glass fiber eqiniswe i-PA6 eshintshiwe ye-chip iyinto efanelekile yokucubungula igobolondo lamathuluzi wamandla, izingxenye zamathuluzi amandla, izingxenye zemishini yokwakha nezingxenye zemoto.Izakhiwo zayo zemishini, ukuzinza kwe-dimensional, ukumelana nokushisa kanye nokumelana nokuguga kuye kwathuthukiswa kakhulu, futhi amandla okukhathala aphindwe izikhathi ezingu-2.5 kunalawo angathuthukisiwe, futhi umphumela wokuguqulwa ubonakala kakhulu.
Inqubo yokubumba yomjovo yama-chips e-PA6 enziwe ngengilazi engu-30% icishe ifane naleyo ngaphandle kokuqiniswa, kodwa ngenxa yokuthi ukugeleza kubi kakhulu kunalokho ngaphambi kokuqiniswa, ingcindezi yomjovo nesivinini somjovo kufanele kukhuliswe ngokufanelekile.Amaphuzu okucubungula ami kanje:
1. Izinga lokushisa lomphongolo lika-30% we-glass fiber eqiniswe i-PA6 kulula ukukhuphuka ngo-10-40 ℃.Izinga lokushisa lomgqomo elikhethelwe ukubunjwa komjovo wama-chips aguquliwe e-PA6 lihlobene nezakhiwo zama-chips ngokwawo, izinto zokusebenza kanye nezici zokwakheka kwemikhiqizo.Izinga lokushisa eliphakeme kakhulu lempahla kulula ukwenza izingxenye zishintshe umbala, i-brittle, i-silver wire kanye nezinye iziphambeko, izinga lokushisa eliphansi kakhulu lombhobho kulula ukwenza lukhuni izinto futhi kulimaze isikhunta nesikulufa.Izinga lokushisa eliphansi lokuncibilika le-PA6 ngu-220C.Ngenxa yobumanzi bayo obuhle, inayiloni igeleza ngokushesha lapho izinga lokushisa lidlula indawo yayo yokuncibilika.I-fluidity yama-chips angu-30% wengilazi aqiniswe i-PA6 eguquliwe iphansi kakhulu kunaleyo yama-chips wezinto ezihlanzekile nama-chips ebanga lomjovo we-PA6, futhi izinga lokushisa lomgqomo kulula ukukhuphuka ngo-10-20 ℃.
2. I-30% ye-glass fibre eqiniswe izinga lokushisa le-PA6 yokucubungula isikhunta ilawulwa ku-80-120C.Izinga lokushisa lesikhunta linethonya elithile ku-crystallinity kanye nokuncipha kokubumba, futhi izinga lokushisa lesikhunta liyi-80-120 ℃.Imikhiqizo enokuqina kodonga oluphakeme kufanele ikhethe izinga lokushisa eliphakeme lesikhunta, elinobucwebe obuphezulu, ukumelana nokugqokwa okuhle, ukwanda kokuqina kanye ne-elastic modulus, ukuncipha kokumuncwa kwamanzi kanye nokwenyuka kokubunjwa kokubunjwa.Imikhiqizo enezindonga ezincane kufanele ikhethe izinga lokushisa eliphansi lesikhunta, elinobucwebe obuphansi, ukuqina okuhle, ubude obuphezulu kanye nokuncipha kokuncipha.Uma ukushuba kodonga kungaphezu kuka-3mm, kutuswa ukusebenzisa isikhunta sokushisa esiphansi ku-20 ℃ kuya ku-40 ℃.Izinga lokushisa lesikhunta lika-30% wezinto eziqinisiwe zengilazi kufanele libe ngaphezu kuka-80 ℃.
3. Ubukhulu bodonga lwemikhiqizo ye-PA6 eqinisiwe yengilazi engu-30% akufanele ibe ngaphansi kuka-0.8mm.Isilinganiso sobude bokugeleza be-PA6 siphakathi kuka-150,200.ubukhulu bodonga lomkhiqizo akumele bube ngaphansi kuka-0.8mm.Ngokuvamile, ukukhetha kuphakathi kwe-1 ~ 3.2mm.Ukuncipha kwemikhiqizo ye-PA6 yengilazi engu-30% eqinisiwe ihlobene nokuqina kodonga lwayo.Ukuqina kodonga, kukhulu ukushwabana.
4. I-exhaust orifice groove kufanele ilawulwe ngaphansi kuka-0.025mm.Inani elichichimayo elinqenqemeni lika-30% we-fiber yengilazi eqiniswe i-PA6 resin licishe libe ngu-0.03mm, ngakho-ke i-exhaust slot kufanele ilawulwe ngaphansi kuka-0.025mm.
5. Ububanzi besango akufanele bube ngaphansi kuka-0.5 kilott (t ukujiya kwengxenye yepulasitiki).Ngesango elingaphansi kwamanzi, ububanzi obuncane besango kufanele bube ngu-0.75mm.
6. Ukuncipha kwemikhiqizo ye-PA6 yengilazi engu-30% eqinisiwe kungancishiswa ibe ngu-0.3%.
Ukuncipha kwempahla ehlanzekile ye-PA6 kuphakathi kuka-1% no-1.5%, futhi ukuncipha kungancipha kube cishe ku-0.3% ngemva kokwengeza u-30% we-fiber fiber reinforcement.Okuhlangenwe nakho okungokoqobo kukhombisa ukuthi lapho kungezwa i-fiber yengilazi eyengeziwe, kuba kuncane ukuncipha kokubumba kwe-PA6 resin.Kodwa-ke, ngokwanda kwenani le-fiber, kuzophinde kubangele i-fiber entantayo, ukungahambisani kahle neminye imiphumela, umphumela wokuqinisa ingilazi we-30% muhle uma kuqhathaniswa.
7. I-30% ye-glass fiber eqiniswe izinto ezigaywe kabusha ze-PA6 akufanele zisetshenziswe izikhathi ezingaphezu kwezingu-3.I-PA6 eqiniswe ngengilazi engu-30% ayinazo izinto ezigaywe kabusha, kodwa uma amakhasimende esebenzisa izinto ezigaywe kabusha eziningi, kulula ukubangela ukushintsha kombala kwemikhiqizo noma ukwehla okubukhali kwezakhiwo zemishini nezomzimba, inani lesicelo kufanele lilawulwe ngaphansi kuka-25%, ngaphandle kwalokho. izobangela ukushintshashintsha kwezimo zenqubo, futhi ukwelashwa okomisa kufanele kwenziwe ngaphambi kokuba izinto ezigaywe kabusha kanye nezinto ezintsha zixutshwe.
8. Inani le-ejenti yokukhulula isikhunta lincane futhi lifana.I-ejenti yokukhululwa yemikhiqizo ye-PA6 eqinisiwe yengilazi engu-30% ingakhetha i-zinc stearate namafutha amhlophe, noma ingaxutshwa kunamathisele, futhi inani elincane le-ejenti yokukhulula lingathuthukisa futhi lisuse amaphutha njengamabhamuza.Ukusetshenziswa kufanele kube kuncane futhi kufane, ukuze kungabangeli ukukhubazeka okungaphezulu kwemikhiqizo.
9. Ngemva kokuba umkhiqizo usuphumile esikhunjeni, uwubeke emanzini ashisayo ukuze uphole kancane.Ngenxa yokuthi i-fiber yengilazi izoqondana nendlela yokugeleza enqubweni yokubumba umjovo, izakhiwo zemishini kanye nokuncipha kuzothuthukiswa lapho kuqondiswa khona, okuholela ekuguquguqukeni nasekujikeni kwemikhiqizo.Ngakho-ke, ekwakhiweni kwesikhunta, isikhundla nokuma kwesango kufanele kube okunengqondo.Izinga lokushisa lesikhunta lingaphakanyiswa kule nqubo, futhi umkhiqizo kufanele ufakwe emanzini ashisayo ukuze uphole kancane.
10. Izingxenye ezingu-30% zengilazi ze-PA6 eziqinisiwe ezisetshenziswa endaweni yokushisa okuphezulu kufanele zifakwe emanzini.Indlela yokulawula umswakama wamanzi abilayo noma isisombululo se-potassium diacetate singasetshenziswa.Indlela yokulawula umswakama wamanzi abilayo ibeka umkhiqizo kumswakama ongu-65% ukuze uthole ukumuncwa okulinganayo komswakama.Izinga lokushisa lokwelashwa kwe-potassium acetate aqueous solution (isilinganiso se-potassium acetate emanzini ngu-1.2515, iphuzu elibilisayo 121C) yisisombululo se-80-100potassium acetate.Isikhathi sokwelashwa sincike kakhulu ekugqineni kodonga lomkhiqizo, lapho ukushuba kodonga cishe amahora angu-2 ku-1.5mm, cishe amahora angu-8 ku-3mm, futhi cishe amahora angu-16-18 ku-6mm.
