Polyamide (PA) ni polymer irimo amide yasubiwemo kumurongo nyamukuru.Akenshi bita Nylon, PA nimwe mubintu byambere byateye imbere kandi bikoreshwa cyane mububiko bwa plastiki.Muri iyi ngingo uyu munsi,Qingdao Sainuoizagutwara kugirango umenye ingingo icumi zingenzi zo guhindura nylon.

ibishasharakuri Nylon yahinduwe

Imiterere yihariye ya nylon ituma ikoreshwa cyane mumodoka, ibikoresho bya elegitoroniki n'amashanyarazi, imiterere yubukanishi, ibikoresho bya siporo, imyenda nibindi.Nyamara, hamwe na miniaturizasi yimodoka, imikorere myinshi yibikoresho bya elegitoroniki n’amashanyarazi, hamwe no kwihutisha inzira y’ibikoresho bya mashini byoroheje, icyifuzo cya nylon n’imikorere yacyo kigenda cyiyongera buhoro buhoro.Guhindura nylon rero ni ngombwa cyane.
Ibintu bikeneye kwitabwaho muguhindura nylon
1. Gushiraho ubushyuhe bwa barriel
(1) Kuberako nylon ari polymer kristaline, aho gushonga biragaragara.Ubushyuhe bwa barrale ya nylon resin muburyo bwo gutera inshinge bifitanye isano nimiterere ya resin, ibikoresho nuburyo bwibicuruzwa.
.
(3) Mubisanzwe, ubushyuhe buke bwo gushonga bwa PA6 ni 220 ℃ naho PA66 ni 250 ℃.Bitewe nubushyuhe buke bwa nylon, ntibikwiye kuguma muri barrale umwanya muremure mubushyuhe bwinshi, kugirango bidatera ibara no guhumeka ibikoresho.Muri icyo gihe, kubera amazi meza ya nylon, atemba vuba iyo ubushyuhe burenze aho bushonga.
2. Ubushyuhe bwubushyuhe
(1) Ubushyuhe bwububiko bugira ingaruka runaka kuri kristu no kugabanuka kugabanuka.Ubushyuhe bwububiko buri hagati ya 80 ℃ kugeza 120 ℃.Ubushyuhe bwo hejuru cyane, kristu yo hejuru, kongera imbaraga zo kwambara, gukomera, modulus ya elastique, kugabanuka kwamazi, kugabanuka kugabanuka, bikwiranye nibicuruzwa bibyibushye;
(2) Niba uburebure bwurukuta burenze mm 3, birasabwa gukoresha ubushyuhe buke hamwe na 20 ~ 40 ℃.Kubirahuri bishimangira ibirahure, ubushyuhe bwububiko bugomba kuba hejuru ya 80 ℃.

3. Urukuta rw'ibicuruzwa
Ikigereranyo cy'uburebure bwa nylon ni 150-200, uburebure bwurukuta rwibicuruzwa ntiburi munsi ya 0.8mm, muri rusange 1-3.2mm, kandi kugabanuka kwibicuruzwa bifitanye isano nubunini bwurukuta rwibicuruzwa.Ubunini bwurukuta runini, niko kugabanuka ari.
4. Umunaniro
Agaciro karenze kuri nylon resin ni 0.03mm, bityo umwobo usohoka ugomba kugenzurwa munsi ya 0.025.
5. Kwiruka n'irembo
Umwobo wa diameter yumuryango ntugomba kuba munsi ya 0.5T (t nubunini bwigice cya plastiki).Irembo ryarohamye, diameter ntarengwa y irembo igomba kuba 0,75mm.
6. Ikirahure cya fibre yuzuye
Muburyo bwo kubumba nylon, kugabanya ubushyuhe bwububiko, kongera umuvuduko watewe no kugabanya ubushyuhe bwibintu bizagabanya kugabanuka kwa nylon kurwego runaka, byongera imihangayiko yimbere yibicuruzwa kandi byoroshye guhinduka.Kurugero, kugabanuka kwa PA66 ni 1.5% ～ 2%, kugabanuka kwa PA6 ni 1% ～ 1.5%, kandi kugabanuka kurashobora kugabanuka kugera kuri 0.3% nyuma yo kongeramo fibre fibre.
Ubunararibonye bufatika butubwira ko uko fibre yongeyeho ibirahure, niko kugabanuka kwa nylon resin.Ariko, niba ikirahuri cya fibre cyongeweho cyane, bizatera fibre ireremba hejuru, kutabangikanya nabi nizindi ngaruka.Mubisanzwe, ingaruka zo kongeramo 30% ni nziza.
7. Gukoresha ibikoresho bitunganijwe neza
Nibyiza kutarenza inshuro eshatu kugirango wirinde ibara ryibara cyangwa kugabanuka gukabije kwimiterere nubukanishi.Amafaranga yo gusaba agomba kugenzurwa munsi ya 25%, byinshi bizatera ihindagurika ryimiterere yimikorere, kandi kuvanga ibikoresho bitunganyirizwa hamwe nibikoresho bishya bigomba gukama.
8. Amabwiriza yumutekano
Iyo nylon resin itangiye, ubushyuhe bwa nozzle bugomba kubanza gukingurwa, hanyuma ubushyuhe bugomba gushyukwa mukigaburo cyo kugaburira.Iyo nozzle ihagaritswe, ntuzigere uhura nu mwobo wa spray, kugirango wirinde kurekurwa gutunguranye gushonga muri barrique yo kugaburira kubera kwirundanyiriza umuvuduko, bishobora guteza akaga.

9. Gusaba umukozi wo kurekura
Gukoresha umubare muto wibikoresho byo kurekura birashobora rimwe na rimwe kunoza no gukuraho ibibyimba nizindi nenge.Umukozi wo kurekura ibicuruzwa bya nylon birashobora kuba zinc stearate namavuta yera, cyangwa kuvangwa na paste.Ingano yo kurekura igomba kuba nto kandi imwe kugirango wirinde ubusembwa.Imashini igomba gusiba mugihe imashini ifunze kugirango wirinde kuvunika mugihe gikurikira.

10. Kohereza imiti
(1) Ibicuruzwa bigomba kuvurwa ubushyuhe nyuma yo kubikora
Uburyo busanzwe mumavuta yubutare, glycerine, paraffine yamazi nandi mazi menshi atetse, ubushyuhe bwo kuvura ubushyuhe bugomba kuba hejuru ya 10 ~ 20 than hejuru yubushyuhe bwo gukoresha, kandi igihe cyo kuvura giterwa nubunini bwurukuta rwibicuruzwa.Umubyimba uri munsi ya mm 3 ni 10 ~ 15 min, ubunini ni 3 ~ 6 mm, naho umwanya ni 15 ~ 30 min.ibicuruzwa nyuma yo kuvura ubushyuhe bigomba gukonjeshwa buhoro buhoro ubushyuhe bwicyumba, kugirango wirinde gukonja gutunguranye bitera kongera kubyara ibibazo mubicuruzwa.
(2) Ibicuruzwa bigomba kuvurwa no kugenzura ubuhehere nyuma yo kubumba
Kugenzura ubuhehere bikoreshwa cyane cyane kubicuruzwa bifite ubuhehere bwinshi.Hariho uburyo bubiri: bumwe ni uguteka amazi meza;Ibindi ni uburyo butose bwa potasiyumu acetate yumuti wamazi (igipimo cya acetate ya potasiyumu namazi ni 1.25: 1, ingingo itetse 121 ℃).
Amazi abira aroroshye, mugihe cyose ibicuruzwa bishyizwe mubidukikije bya 65% by'ubushuhe, kuburyo bishobora kugera kubutaka bwa equilibrium, ariko igihe ni kirekire.Ubushyuhe bwo kuvura umuti wa potasiyumu acetate ni 80 ~ 100 and, kandi igihe cyo kuvura ahanini giterwa nubunini bwurukuta rwibicuruzwa, mugihe uburebure bwurukuta ari 1.5mm, hafi 2h, 3mm, 8h, 6mm, 16 ~ 18h.
