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 lezinto eziqiniswe ingilazi elingu-30% 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.
