1. Inzira yibanze
Hamwe niterambere ryihuse ryinganda zigezweho, cyane cyane inganda za shimi, hari ubwoko butandukanye bwibicuruzwa bya rubber, ariko umusaruro wabo ni kimwe. Igikorwa cyo gukora ibicuruzwa gikozwe muri reberi ikomeye (reberi mbisi) ahanini ikubiyemo:
Kwitegura Ibintu → Plastiki
2. Gutegura ibikoresho fatizo
Ibikoresho nyamukuru byibicuruzwa bya rubber birimo reberi mbisi, abakozi bayongereye, ibikoresho bya fibre, nibikoresho byicyuma. Muri bo, Rubber mbisi ni ibintu by'ibanze; Umukozi uteye imbere ni ibintu bifasha byongewe kugirango atezimbere imitungo imwe y'ibicuruzwa; Ibikoresho bya fibre (ipamba, imyenda, ubwoya, fibre zitandukanye zubukorikori, ibikoresho bya synthique) bikoreshwa nkibikoresho bya rubber kugirango bishyireho imbaraga zubururu no kugabanya imiterere yubuka ryubukanishi no kugabanya ibikoresho byubukanishi no kugabanya ibikoresho byubukaningubu.
Mugihe cyibikoresho byo gutegura ibintu, ibiyigize bigomba gufatwa neza ukurikije formula. Kugirango reberi mbisi hamwe numukozi utera ubwumvikane kugirango uvange neza, ibikoresho bimwe bigomba gutunganywa:

Kwitegura Ibintu → Plastiki
2. Gutegura ibikoresho fatizo
Ibikoresho nyamukuru byibicuruzwa bya rubber birimo reberi mbisi, abakozi bayongereye, ibikoresho bya fibre, nibikoresho byicyuma. Muri bo, Rubber mbisi ni ibintu by'ibanze; Umukozi uteye imbere ni ibintu bifasha byongewe kugirango atezimbere imitungo imwe y'ibicuruzwa; Ibikoresho bya fibre (ipamba, imyenda, ubwoya, fibre zitandukanye zubukorikori, ibikoresho bya synthique) bikoreshwa nkibikoresho bya rubber kugirango bishyireho imbaraga zubururu no kugabanya imiterere yubuka ryubukanishi no kugabanya ibikoresho byubukanishi no kugabanya ibikoresho byubukaningubu.
Mugihe cyibikoresho byo gutegura ibintu, ibiyigize bigomba gufatwa neza ukurikije formula. Kugirango reberi mbisi hamwe numukozi utera ubwumvikane kugirango uvange neza, ibikoresho bimwe bigomba gutunganywa:
Rubber mbisi igomba kwiyoroshya muri 60-70 icyumba cyumisha mbere yo gutemwa no gucikamo ibice bito;
Guhagarika nkinyongera nka paraffin, acide yijimye, rosin, nibindi bigomba guhonyora;
Niba ibishishwa byifu birimo umwanda wubuka cyangwa uduce duto, bigomba kumenyera no gukurwaho;
Inyongeramuzi z'amazi (pine tar, coumarone) bisaba gushyushya, gushonga, guhimba amazi, no gushungura umwanda;
IGIKORWA CY'IGIHUGU BIGIRA HANZE, Bitabaye ibyo bikunda guhitana kandi ntibishobora kutanyeta mugihe uvanze, bikaviramo ibituba mugihe cyo gutera inkunga no kugira ingaruka ku miterere y'ibicuruzwa;
3. Kunonosora
Rubber mbis ni elastike kandi ibura imitungo ikenewe (plastike) yo gutunganya, bigatuma bigora. Kugirango utezimbere plakiyeri, birakenewe ko tunonosora reberi mbisi; Muri ubu buryo, umukozi uvanze aratatana byoroshye muri reberi mbisi mugihe cyo kuvanga; Muri icyo gihe, mugihe cyo kuzunguruka no gushinga inzira, bifasha kandi kuzamura ibintu bya reberi (byinjira mumyenda ya fibre) hamwe nuburyo bwo gukora. Inzira yo gutesha agaciro molekile ndende ya reberi mbisi kugirango ukore plastike yitwa plastisation. Hariho uburyo bubiri bwo gutunganya reberi mbisi: gutunganya neza no gutunganya ubushyuhe. Icyuma cya mashini ninzira yo kugabanya iyangirikana rya reberi ndende kandi rikayihindura kuva muburyo bwa solacique binyuze mu mikorere ya plastike no guterana amagambo ya plastiki ugereranije nubushyuhe bwo hasi ugereranije nubushyuhe buke ugereranije. Gutunganya gukandagira gukabije ni inzira yo kumenyekanisha umwuka ushyushye muri reberi mbisi, ikigiro cyubushyuhe na ogisijeni, kugirango ugabanye molekile ndende, kugirango ubone plastique.
4. Kuvanga
Kugirango uhuze n'imiterere itandukanye, kugera ku mikorere itandukanye, no kunoza imikorere y'ibicuruzwa bya rubber no kugabanya ibiciro, birakenewe kongeramo inyongeramusaruro kuri reberi mbi. Mixing is a process of mixing the plasticized raw rubber with the compounding agent and placing it in a rubber mixer. Binyuze muburyo bwo kuvanga, umukozi utera imbere rwose kandi umwe ukwirakwizwa muri reberi mbisi. Kuvanga ni inzira yingenzi mugukora ibicuruzwa bya rubber. Niba kuvanga bitarenze, uruhare rwa reberi ninyongera ntibushobora gukoreshwa byuzuye, bigira ingaruka kumikorere yibicuruzwa. Ibikoresho bya rubber byabonetse nyuma yo kuvanga, bizwi nka reberi ivanze, nibikoresho byarangiye bikoreshwa mugukora ibicuruzwa bitandukanye bya rubber, mubisanzwe bizwi nkibikoresho bya reberi. Mubisanzwe bigurishwa nkibicuruzwa, kandi abaguzi barashobora gutunganywa kandi bagaterana ibikoresho bya rubber kugirango bitanga ibicuruzwa bisabwa. Dukurikije formulaire zitandukanye, reberi ivanze ifite urukurikirane rwibiciro bitandukanye hamwe nubwoko bifite ibintu bitandukanye, gutanga amahitamo.
5. Gushiraho
Muburyo bwo gukora ibicuruzwa bya Rubber, ikoreshwa rya mashini izunguruka cyangwa yinjiye mbere yimiterere nubunini butandukanye byitwa kubumba. Uburyo bwo gushinga ibirimo:
Kuzunguruka bikwiranye no gukora impapuro zoroshye hamwe nibicuruzwa bya plaque. Nuburyo bwo gukanda reberi ivanze muburyo bumwe nubunini bwa firime ukoresheje imashini izunguruka, yitwa kuzunguruka. Ibicuruzwa bimwe bya rubber (nk'ipine, kaseti, ingofero, n'ibindi) koresha ibikoresho bya fibre bigomba guhita bifatika (bizwi kandi bizwi kumyandikire cyangwa bizwi cyane ku imashini izunguruka. Ibikoresho bya fibre bigomba gukama no gutangwa mbere yo kuzunguruka. Intego yo kumisha ni ukugabanya ibintu byubushuhe bwibikoresho bya fibre (kugirango wirinde guhumeka no kubyimba) no kunoza
