ItsindaUburyo bwo gushushanya ibikoresho bya SMCni yo ikora neza cyane mu gutunganya ibikoresho bya pulasitiki/ibirahuri. Uburyo bwo gutunganya ibikoresho bya SMC bufite ibyiza byinshi, nko: ingano nyayo y'ibicuruzwa, ubuso bworoshye, imiterere myiza y'ibicuruzwa n'ingano isubiramo, imiterere igoye ishobora no gutegurwa icyarimwe, gutunganya ibikoresho bidasaba kwangiza ibicuruzwa, nibindi. Ariko, inenge mbi nazo zizagaragara mu gutunganya ibikoresho bya SMC, ahanini zigaragarira mu mpamvu zikurikira:
(I)Kubura ibikoresho: Kubura ibikoresho bivuze ko ibice bya SMC bitaba byuzuye, kandi aho bikorerwa ahanini biba biri ku nkengero z'ibicuruzwa bya SMC, cyane cyane imizi n'inyuma y'imfuruka.
(a) Gusohora ibintu bike
(b) Ibikoresho bya SMC bifite ubushyuhe buke
(C) Umuvuduko w'ibikoresho udahagije
(d) Gukira vuba cyane
Uburyo bwo gukora no guhangana n'ingaruka:
①Iyo ibikoresho bya SMC bikozwe muri pulasitiki hakoreshejwe ubushyuhe, ubushyuhe bushongesha buba bunini. Mbere y'uko uburyo bwo guhuza no gushonga burangira, nta gihe gihagije, igitutu, n'ingano bihagije byo kuzuza umwobo w'ibumba n'ubushyuhe.
②) Igihe cyo kubika ibikoresho byo gushushanya bya SMC ni kirekire cyane, kandi styrene irahindagurika cyane, bigatuma imiterere y'imikoreshereze y'ibikoresho byo gushushanya bya SMC igabanuka cyane.
③Ifu ya resin ntiyinjiye muri fibre. Ifu ya resin ntishobora gutuma fibre itemba mu gihe cyo gushushanya, bigatuma ibikoresho bibura. Kubera ibura ry'ibikoresho riterwa n'impamvu zavuzwe haruguru, igisubizo kigaragara ni ukuvanaho ibyo bikoresho byabumbwe mu gihe cyo gukata ibikoresho.
④Ubwinshi budahagije bw'ibiryo butera ibura ry'ibikoresho. Umuti ni ukongera ingano y'ibiryo uko bikwiye.
⑤Hari umwuka mwinshi cyane n'ibintu byinshi bihindagurika mu bikoresho byo gushushanya. Igisubizo ni ukongera umubare w'imyotsi isohoka mu buryo bukwiye; kongera neza aho kugaburira no gupfunyika mu gihe runaka kugira ngo woze ifuro; kongera neza umuvuduko w'ifuro.
⑥Umuvuduko uratinze cyane, kandi ibikoresho byabumbwe byarangije guhuza no gushonga mbere yo kuzuza umwobo w'ibihumyo. ⑦Niba ubushyuhe bw'ibihumyo buri hejuru cyane, uburyo bwo guhuza no gushonga buzatera imbere, bityo ubushyuhe bugomba kugabanuka neza.
(2)Stoma.Hari utwobo duto duto cyangwa duto ku buso bw'umusaruro, inyinshi muri two zikorerwa hejuru no hagati mu nkuta nto z'umusaruro.
Uburyo bwo gukora no guhangana n'ingaruka:
①Ibikoresho byo gushushanya bya SMC birimo umwuka mwinshi kandi ibintu bihindagurika ni byinshi, kandi imyuka isohoka ntabwo yoroshye; ingaruka zo gukomera kw'ibikoresho bya SMC si nziza, kandi umwuka ntushobora gusohoka neza. Impamvu zavuzwe haruguru zishobora kugenzurwa neza no kongera umubare w'imyobo no gusukura ifumbire.
②Aho kugaburira ni hanini cyane, kugabanya neza aho kugaburira bishobora kugenzurwa. Mu gikorwa nyacyo, ibintu bikomoka ku bantu nabyo bishobora gutera trachoma. Urugero, niba umuvuduko w'umwuka utangiye kare cyane, bishobora kugorana ko umwuka upfunyitse mu gice cyo kubumba ushobora gusohoka, bigatuma habaho inenge ku buso nk'imyenge ku buso bw'umusaruro.
(3)Warpage no guhindura imiterere y'ibintuImpamvu nyamukuru ni ukudahinduka kw'imvange y'ibumba n'igabanuka ry'umusaruro nyuma yo gusenyuka.
Uburyo bwo gukora no guhangana n'ingaruka:
Mu gihe cy’ihinduka ry’imvange y’imvange, imiterere y’imiti irahinduka, bigatuma ingano igabanuka. Uburyo bumwe bw’imvange butuma ibicuruzwa bikunda kugorama ku ruhande rwa mbere rwavuwe. Icya kabiri, ingano y’ubushyuhe bw’ibicuruzwa iba nini kuruta iy’icyuma. Iyo ibicuruzwa bikonje, igipimo cyabyo cyo kugabanuka k’uburyo bumwe kiba kinini kuruta igipimo cyo kugabanuka k’ubushyuhe bw’uburyo bumwe bw’imvange. Muri urwo rwego, hakoreshwa uburyo bukurikira kugira ngo ikibazo gikemuke:
①Gabanya itandukaniro ry'ubushyuhe hagati y'ibimera byo hejuru n'ibyo hasi, kandi ushyireho uburyo ubushyuhe bungana uko bishoboka kose;
② Koresha ibikoresho byo gukonjesha kugira ngo ugabanye imihindagurikire y'ikirere;
③Ongera neza igitutu cyo gushushanya, wongere ubucucike bw'inyubako y'umusaruro, kandi ugabanye umuvuduko wo gucika kw'umusaruro;
④ Kongera igihe cyo kubika ubushyuhe neza kugira ngo ugabanye umuvuduko w'imbere mu mubiri.
⑤Hindura igipimo cyo gushonga kw'ibikoresho bya SMC.
(4)Kurandura.Uduce duto tw’uruziga ku buso bw’umuti wavuwe.
Uburyo bwo gukora no guhangana n'ingaruka:
Birashoboka ko ibikoresho bitarakira neza, ubushyuhe bwo mu gace kabyo buri hejuru cyane, cyangwa ibintu bihindagurika cyane mu bikoresho bikaba ari byinshi, kandi umwuka ufata hagati y’amashuka, bigatuma igice cy’uruziga kibyimba ku buso bw’umusaruro.
(①Iyo wongereye umuvuduko wo gushushanya
(②Ongera igihe cyo kubika ubushyuhe
(③) Gabanya ubushyuhe bw'ibihumyo.
④Gabanya ahantu ho kuruhuka
(5)Ibara ry'ubuso bw'ibicuruzwa ntiringana
Uburyo bwo gukora no guhangana n'ingaruka:
①Ubushyuhe bw'ibihumyo ntibungana, kandi igice cyabyo kiri hejuru cyane. Ubushyuhe bw'ibihumyo bugomba kugenzurwa neza;
②Uburyo bwo gushushanya ibintu budafite ubushyuhe bwinshi, bigatuma fibre ikwirakwira mu buryo butaringaniye, muri rusange bishobora kongera umuvuduko w'ubushyuhe kugira ngo byongere ubushyuhe bw'ubushyuhe;
③Ibara ry'umukara n'umusemburo ntibishobora kuvangwa neza mu gihe cyo kuvanga ibara ry'umusemburo.
