Ibiranga nuburyo bwo gutunganya inshinge za plastike bigira ingaruka kubintu byinshi.Plastiki zitandukanye zigomba gukora ibipimo byerekana imiterere yabyo kugirango ubone ibikoresho byiza bya mashini.
Gutera inshinge ingingo zikurikira:
Imwe, igipimo cyo kugabanuka
Ibintu bigira ingaruka kumiterere yo kugabanuka kwa plastiki ya termoplastique nibi bikurikira:
1.Ubwoko bwa plastiki
| OYA. | Plastikeizina | ShrinkageRyariye |
| 1 | PA66 | 1% –2% |
| 2 | PA6 | 1% –1.5% |
| 3 | PA612 | 0.5% –2% |
| 4 | PBT | 1.5% –2.8% |
| 5 | PC | 0.1% –0.2% |
| 6 | POM | 2% –3.5% |
| 7 | PP | 1.8% –2.5% |
| 8 | PS | 0.4% –0.7% |
| 9 | PVC | 0.2% –0,6% |
| 10 | ABS | 0.4% –0.5% |
2.Ubunini nuburyo byububiko.Ubunini bwurukuta rwinshi cyangwa sisitemu mbi yo gukonjesha irashobora kugira ingaruka kugabanuka.Mubyongeyeho, kuba cyangwa kutaboneka kwinjizwamo hamwe nimiterere nubunini bwinjiza bigira ingaruka muburyo butaziguye icyerekezo cyogutemba, gukwirakwiza ubwinshi no kugabanuka kugabanuka.
3.Uburyo, ingano no gukwirakwiza umunwa wibintu.Izi ngingo zigira ingaruka zitaziguye ku cyerekezo cyo gutembera kw'ibintu, gukwirakwiza ubucucike, gufata umuvuduko no kugabanuka no gukora igihe.
4.Ubushyuhe bwinshi hamwe nigitutu cyo gutera inshinge.
Ubushyuhe bwubushyuhe buri hejuru, ubwinshi bwashonge ni bwinshi, igipimo cyo kugabanuka kwa plastike ni kinini, cyane cyane plastiki ifite kristu nyinshi.Ikwirakwizwa ry'ubushyuhe n'ubucucike bw'ibice bya pulasitike nabyo bigira ingaruka ku kugabanuka no ku cyerekezo.
Kugumana igitutu nigihe bimara nabyo bigira ingaruka mukugabanuka.Umuvuduko mwinshi, umwanya muremure uzagabanuka ariko icyerekezo ni kinini.Kubwibyo, iyo ubushyuhe bwubushyuhe, umuvuduko, umuvuduko wo gutera inshinge nigihe cyo gukonjesha nibindi bintu nabyo birashobora kuba byiza guhindura igabanuka ryibice bya plastiki.
Igishushanyo mbonera ukurikije uburyo butandukanye bwo kugabanuka kwa plastike, uburebure bwurukuta rwa plastike, imiterere, kugaburira inlet ingano no kugabura, ukurikije uburambe kugirango hamenyekane kugabanuka kwa buri gice cya plastiki, hanyuma ubare ubunini bwurwobo.
Kubice bya plastike bihanitse kandi biragoye kumva igipimo cyo kugabanuka, mubisanzwe birakwiye gukoresha uburyo bukurikira mugushushanya ibishushanyo:
a) Fata igabanuka rito ry'ibice bya pulasitike muri diameter yo hanze no kugabanuka binini kugirango ubone umwanya wo guhinduka nyuma yo gupimwa.
b) Ikizamini cyibishushanyo kugirango umenye imiterere ya sisitemu ya casting, ingano nuburyo bwo gukora.
c) Ingano ihinduka ryibice bya plastiki igomba gusubirwamo bigenwa nyuma yo gusubirwamo (gupima bigomba kuba nyuma yamasaha 24 nyuma yo kwiyambura).
d) Hindura ifumbire ukurikije kugabanuka kwukuri.
e) Urupfu rushobora gusubirwamo kandi agaciro ko kugabanuka kurashobora guhinduka gato muguhindura uburyo bukwiye kugirango byuzuze ibisabwa mubice bya plastiki.
Icya kabiri,Amazi
- Amazi ya thermoplastique akunze gusesengurwa nuruhererekane rwibipimo nkuburemere bwa molekile, indangagaciro, gushonga kwa Archimedes, uburebure bwimikorere no kugereranya (uburebure bwurukuta / uburebure bwurukuta rwa plastike).Kuri plastiki yizina rimwe, ibisobanuro bigomba kugenzurwa kugirango hamenyekane niba amazi yabyo akwiriye kubumba inshinge.
Ukurikije ibishushanyo mbonera bisabwa, amazi ya plastiki akunze gukoreshwa arashobora kugabanywa mubice bitatu:
a) Amazi meza ya PA, PE, PS, PP, CA na polymethylthyretinoene;
b) Urwego ruciriritse rwa polystirene resin (nka AS ABS, AS), PMMA, POM, polifhenyl ether;
c) Amazi mabi PC, PVC ikomeye, polifhenyl ether, polysulfone, sulfone polyaromatic, plastike ya fluor.
- Amazi ya plastike atandukanye nayo arahinduka bitewe nibintu bitandukanye.Ibintu nyamukuru bigira ingaruka ni ibi bikurikira:
a) Ubushyuhe.Ubushyuhe bwo hejuru buzamura ubwinshi, ariko plastiki zitandukanye nazo ziratandukanye, PS (cyane cyane kurwanya ingaruka nigiciro kinini cya MFR), PP, PA, PMMA, ABS, PC, CA ya plastike ihindagurika nubushyuhe.Kuri PE, POM, noneho ubushyuhe bwiyongera no kugabanuka ntacyo bihindura kumikorere yabyo.
b) Umuvuduko.Umuvuduko wo gutera inshinge wongera gushonga kubikorwa byogosha, ubwinshi nabwo bwiyongera, cyane cyane PE, POM irumva cyane, igihe rero cyo gutera inshinge zo kugenzura imigendekere.
c) Gupfa imiterere.Nka gusuka sisitemu ya sisitemu, ingano, imiterere, sisitemu yo gukonjesha, sisitemu yogusohora nibindi bintu bigira ingaruka zitaziguye kumyuka yibintu byashongeshejwe mukuzimu.
Igishushanyo mbonera kigomba gushingira kumikoreshereze yimyenda ya pulasitike, hitamo imiterere ikwiye.Gushushanya birashobora kandi kugenzura ubushyuhe bwibintu, ubushyuhe bwibumba hamwe nigitutu cyo gutera inshinge, umuvuduko wo gutera inshinge nibindi bintu kugirango uhindure neza ibyuzuye kugirango uhuze ibyifuzo.
