Imitungo nuburyo bwo gutunganya ibipimo bya plastike bigira ingaruka kubintu byinshi. Plastics zitandukanye zigomba gutegura ibipimo byo gukora bikwiranye numutungo wabo kugirango ubone imitungo myiza.
Gutera inshinge ingingo ni izi zikurikira:
Igipimo kimwe, agabarika
Ibintu bigira ingaruka kumihanda yo gushinga ibishushanyo mbonera byimitwe niyi ikurikira:
1.Ibikoresho bya plastiki
| Oya. | Plastikiizina | 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. ingano n'imiterere yububiko. Urukuta rukabije cyangwa sisitemu yo gukonjesha irashobora kugira ingaruka kumanuka. Byongeye kandi, kuboneka cyangwa kubura kwinjiza hamwe nuburyo bwinshi bwinjiza bigira ingaruka muburyo bwubuyobozi, gukwirakwiza ubucucike no kurwanya aganganya.
3.Uburyo, ingano no gukwirakwiza umunwa wibintu. Ibi bintu bigira ingaruka muburyo bwibintu bifatika, gukwirakwiza ubucucike, guhagarika umutima no kugabanuka no gushinga igihe.
4.Muraburiye ubushyuhe no gutera inshinge.
Ubushyuhe bwa Mold ni bwinshi, Gushonga ni ikipimo kinini, cyane cyane igipimo cya plastiki kiri hejuru, cyane cyane plastike hamwe na karita ndende. Gukwirakwiza ubushyuhe n'ubucucike bumwe n'ibice bya plastike nabyo bigira ingaruka kumyanda n'icyerekezo.
Kugumana igitutu ndetse nigihe nabyo bigira ingaruka ku kwikuramo. Umuvuduko mwinshi, igihe kinini kizagabanuka ariko icyerekezo ni kinini. Kubwibyo, iyo ubushyuhe bukabije, igitutu, gushimura umuvuduko no gukonjesha igihe nibindi bintu birashobora kandi kuba bikwiye guhindura aganganya ibice bya plastike.
Igishushanyo mbonera ukurikije imiterere itandukanye ya plastiki, urukuta rwa plastike, imiterere, kugaburira inzitizi, ukurikije uburambe bwo kumenya kugabanuka kwa buri gice cya plastike, hanyuma kubara ingano ya kavike.
Ku rwego rwo hejuru cyane kandi biragoye kubyumva igipimo cya gari ntoya, muri rusange birakwiye gukoresha uburyo bukurikira bwo gutegura ibumba:
a) Fata agace gato k'ibice bya plastike muri diameter yo hanze hamwe no kugabanuka gukomeye kugirango ugire umwanya wo guhindura nyuma yikizamini cya mold.
b) Ikizamini cya Mold kugirango umenye ifishi ya sisitemu, ingano no gushiraho imiterere.
c) Ingano ihindura ibice bya plastike igomba gusubirwamo bigenwa nyuma yo gusubiraho (igipimo kigomba kuba amasaha 24 nyuma yo kwiyambura).
d) Hindura uburyo ukurikije imyanda nyayo.
e) Gupfa birashobora gusubirwamo kandi agaciro kagabanijwe gashobora guhinduka gato muguhindura imiterere muburyo bukwiye kugirango duhuze ibisabwa nibice bya plastike.
Icya kabiri,Amazi
- Amazi yibikoresho bisanzwe asesengurwa nuruhererekane rwibipimo nkibiro bya molecular, gushonga, archimede yuburebure bwa spiral, uburebure bwimikorere / uburebure bwa plastike). Kuri plastiki yizina rimwe, ibisobanuro bigomba kugenzurwa kugirango umenye niba amazi yabo akwiriye gucika intege.
Ukurikije ibisabwa byose, amazi ya plastiki akoreshwa arashobora kugabanywa mubyiciro bitatu:
a) Amazi meza ya pa, Pe, PS, PP, CP, CA na PolymeyylyTreinoene;
b) Gucika intege cyane Polystyrene resin Urukurikirane (nka ABS, AS), PMMma, Poly, Polyphenyl ether;
c) Amazi mabi PC, PVC ikomeye, Polyphenyl Ether, Polsalfone, Sulfone ya Polyaroma, Polyaromatic, Sluorine.
- Amazi yibishushanyo bitandukanye nabyo birahinduka kubera ibintu bitandukanye bikora. Ibyiringiro nyamukuru bigize ingaruka zikurikira:
a) ubushyuhe. High material temperature will increase the liquidity, but different plastics are also different, PS (especially impact resistance and higher MFR value), PP, PA, PMMA, ABS, PC, CA plastic liquidity with temperature change. Kuri pe, pom, kongera ubushyuhe no kugabanuka gafite uruhare ruto kuborora.
b) igitutu. Gutera ubwoba igitugu cyongera gushonga na kose
c) imiterere. Nka sisitemu yo gusuka, ingano, imiterere, sisitemu yo gukonjesha, sisitemu yo kunezeza nibindi bintu bigira ingaruka muburyo butunguranye bwibikoresho bishongeshejwe mu cyuho.
Igishushanyo mbonera kigomba gushingira ku gukoresha plastike gutemba, hitamo imiterere ishyize mu gaciro
