Okukora ebintu ebitari bimwe na bimwe eby’obuveera okukira munonga n’omuringo gw’okusheenya, okusheesheka n’okukyendeeza obucweka bw’emipiira kuba ebintu ebihweire bwanyima y’okubiteeka. Ni omuringo gw’okwotsya reero okakyendeeza. Kandi n’omuringo gw’okuhindura obuveera kuruga omu bicweka by’omubiri kuza omu miringo etari emwe n’emwe. Ahabw'aba ekyoma ky'okukora obuveera, omuringo gwona nigubaasa kuhindurwa kubaasa kukora omu bwijwire hatariho kukoresa emikono, kandi omutindo gw’ebintu nigugumaho! Ebi ahaifo nibiija kushoboorora enkora y‘okukora kuruga omu kureeba emitendekyere etari emwe n‘emwe.
1. Saanuura
Ekirikureeta obutagatsi omu kikwato eki nikireetera obucweka bw’ebintu ebitari birungi kusheenya mpora mpora bikahinduka amaizi. Ebintu ebitari bimwe na bimwe ebikozirwe nibikira kuba birungi omu kuhindura ebirikuba biriho. Okwongyera aha bwire bw’obwire nikiija kutunguura okutambura kw’ebintu ebitari bimwe na bimwe, ekirikubaasa kwongyera aha busingye, kwonka tikirikwetengyesa kuhamya ngu eby’okurya byatunga. Okugyeragyeranisa okuhikire kushemerire kuhikirizibwa. Okwongyera ahari ekyo, ekirungi ekirikurugamu n’emitwarize ya PP omu mbeera y’okusharaho kw’okwotsya kwingi n’okugira ngu nikirungi kukora ngu ekintu ekikozirwe kigyende gye kuhika aha die omu bwire bw’okukora, kugira ngu hatabaho okujwisa okutarikumara nari okugaruka enyima. Reflux nikimanyisa ngu okutambura kw‘ebintu ebitari bimwe na bimwe nikurahuka kukira omubaro gw‘ebirikurugamu, kandi aha muheru kwongyera aha nkora y‘okutambura kwa purayimare, erikwingana n‘okutunguuka kwa MFR. Ni gumwe aha miringo eriho ey‘okukora, Kwonka, neereetaho n‘okugabwa kwa MFR okutari kwa buriijo, ekirikubaasa kureetera okweyongyera kw‘obutagumizamu n‘okwongyera aha mubaro gw‘oburemeezi. Kwonka ahabw‘okukoresa, ebintu ebihweire PP ti bintu ebiine obuhame bw‘ahaiguru, n‘ahabw‘ekyo ebirikurugamu ti bingi.
2.Empimbi y'okuteeraho
Ebicweka bingi eby’okukora PP nibirugiirira aha nshaho y’okuvuga amaizi, n’ahabw’ekyo oku enshaho yaakozirweho kwine akakwate kakuru. Diamita neekwata aha birikurugamu, kandi omubaro gw’okunyigirizibwa nigukwata aha muheendo gwa pressure. Kandi nikikwata aha birugiremu n‘ebirikurugamu ebihweire, obariiremu n‘okutabura ebintu bitari bimwe na bimwe (Color Masterbatch, eby‘okwongyeramu n‘ebirikuhindura). Okutambura kw’ebintu ebitari bimwe na bimwe nikurugiirira munonga aha kirikwotsya, kwonka okuteerana n’okuteerana kw’ebintu ebikozirwe nabyo nibiija kureetaho amaani g’okwotsya g’okuteerana kutunguura okusheesheka. Nahabwekyo, omubaro gw’okunyiganyiga kw’ekikwato ky’okuteeraho nigukye, okusheesheka ni kukye, kandi omuvuyo gw’okuzirika guteekwa kwongyerwaho, ekirikureetaho amaani g’okwotsya g’okuteerana kukira ekikwato ekiine omubaro gw’okuteerana kwingi. Nahabwekyo, nikikira kugambwa ngu tihariho muhangu omukukora obuveera, kandi omuntu orikwetegyereza kurungi oku ekyoma kirikukora niwe muhangu. Okwotsya ebintu ebitari bimwe na bimwe ti kwotsya kwonka, kureka n‘okwotsya kw‘okuteerana n‘obwire bw‘okufuka. N’ahabw’ekyo, eki n’ekizibu ekirikukoresibwa. Okumanya nikuhwera omu kushoboorora oburemeezi bw‘okukora n‘okutunguura okukora gye. Okutabura kw‘ekikwato ky‘okuteeraho kwaba kuri kurungi munonga, obumwe ebikwato by‘okutabura eby‘emitendekyere ebiri nari ebikwato by‘okuteerana eby‘emiringo ebiri nibikorwa, kandi buri kicweka ky‘emiringo y‘ekikwato ky‘okutabura etari emwe n‘emwe nikiteebwaho omu muringo gw‘okwetaanisaho kubaasa kutunga okutabura kw‘ebikwato by‘okutabura etari emwe n‘emwe.
3. Okufa nari kufa omutwe .
Okugaruzaho obuveera nikirugiirira aha mutwe gw’ekibumbe nari ogw’okufa. Ekintu ekirikuhwaho omu kubumba enjegyere kirimu emiringo eshatu, kandi ekibumbe nakyo kigumire. Ekizibu ky‘okukyendeeza kiine kuteekateekwaho. Ebindi bikoreso ni enyonyi, strip n’empiira ezirikugumizamu ebintu ebirikufa. Ku biraabe biri ebishushani by’omutaano, nibishoroorwa nk’ebishushani by’omutaano. Okuta omutima aha buremeezi bw‘okukyendeeza ahonaaho n‘okupima obuhango. Ebyoma by’obuveera ebingi bikozirwe nk’empiso. Amaani g‘okushohoza agarikuvugwa ekikwato ky‘okushohoza nigaija kureetera okugyemeserezibwa kwingi aha nshonda nkye kandi gatunguure okukora gye. Omutwe gw’okufa gwaba gutebeekanisiibwe nk’enyonyi, oku orikubaasa kukora ebintu ebitari bimwe na bimwe bikagabwa gye aha itaka ryona, okukora omutwe gw’okufa ogw’okuhanikaho emyenda ni kikuru munonga. Fayo aha mugisha gw‘okushohoza kwongyera aha pampu y‘ebihimba by‘eby‘enyanja n‘okuhamya okutunga ebintu ebitari bimwe na bimwe.
4. Okukyendeeza
Oyihireho okushuka ebintu ebitari bimwe na bimwe omu irembo rya sprue, ekibumbe ky’okuteeramu enjegyere nakyo kiine omuringo gw’okukyendeeza ebintu ebitari bimwe na bimwe omu muhanda gw’okukyendeeza. Okubumba kw’okushohoza (extrusion molding) nikugyendera aha muhanda gw’amaizi g’okukyendeeza obutagatsi omu rubaaho kubaasa kutunga ekirugire omu kukyendeeza obutagatsi. Okwongyera ahari ekyo, hariho n’ebikwato by’omuyaga, amaizi g’okukyendeeza oburofa agateirwe butunu aha nshaho y’okufuka, okufuka omu biina n’emiringo endiijo y’okufuka.
5. Okwongyera
Okugaruka kukora aha kintu ekihweire n’okukiyongyera aha kintu nikiija kwongyera aha nkora. Nk’eky’okureeberaho, sipiidi etari emwe n’emwe ey’omusipi gw’okupakira ogurikuvugwa ebikwato by’omu maisho n’eby’enyima nibiija kureetera okutunguuka. Amaani g’okuteera ekicweka ky’okutunguura eky’ekintu ekihweire nigahamibwa, ekitari kyorobi kusheenya, kwonka kyorobi munonga kusheenya omu rubaju. Okugabanisa oburemeezi bwa molekyu nakyo nikiija kukwata aha nkora y‘okwongyera omu kuhanga ebintu omu sipiidi mpango. Ebintu byona ebishohoziibwe, otwariiremu n’ebihimba, biine okutunguuka okutarikushushana. Okuhangaho omuyaga gw’omuyaga n’omuyaga ogurikunyigirizibwa nakyo nikibaasa kuteekateekwaho nk’omuringo ogundi gw’okutunguura.
6. Kukyendeera
Ekintu kyona ekikozirwe kiine oburemeezi bw’okukyendeera, ekirikureetwa okushoberwa kw’omunda omu bwire bw’okutunguuka kw’okwotsya, okukyendeera kw’obufuki n’okuhinduka kw’ekibiriiti. Okutwarira hamwe, okutunguuka kw’okwotsya n’okukyendeera omu bwire bw’obufuki nibyanguhi kusingura, ekirikubaasa kukorwa orikutunguura obwire bw’okukyendeeza omu kukora n’okurinda omuhimbo obutoosha. Ebintu ebikozirwe omu nkora ya crystalline nibikira kuba biine entaaniso mpango y‘okukyendeera kukira ebikozirwe omu nkora ya crystalline, nka 16% ahari PP, kwonka nka 4% zonka ahari ABS, ekirikutaana munonga. Ekicweka eki nikyetengyesa kusingurwa aha kicupuri, nari eby’okwongyeramu kukyendeeza aha nkora y’okukyendeeza nibikira kwongyerwamu, LDPE neekira kwongyerwa aha rupapura rw’okushohoza kubaasa kutunguura ekizibu ky’okuteera enshaya.
Ekyoma ky’okukora ebishushani by’obuveera nikikora haihi aha biveera byona ebirikwotsya. Omu myaka egi, ekyoma ky’okukora obuveera oburikwotsya nakyo kikoresiibwe gye kuhanga obuveera obumwe oburikuguma nibukora nk’obuveera. Omuringo gw’okubumba eby’okukoresa eby’obuveera ebirikukora obutagatsi nigukye (obutikitiki bukye kuhika aha dakiika nkye), kandi nikibaasa kubumba ebibumbe ebiine ekishushani ekigumire, obuhango obuhikire kandi omu bwire bumwe. Ebintu by’ebyoma bya GTMSMART ebirikukora eby’okwotsya birimu Ekyoma ky'okukora eby'obuveera, Ekyoma ky'okukora ekikopo ky'okwotsya, Ekyoma ky'okukora obuveera, Ekyoma ky'okukora ebimuri omu nyungu y'obuveera.
GTMObwengye okuha ebyoma by’omutindo gw’okubanza aha muheendo murungi munonga ebirikubaasa kuhikiiriza ebyetaago byawe by’okukora ebintu bingi omu muringo gworobi. Reeba ebintu byaitu ebitari bimwe na bimwe kandi noija kushanga ebintu bingi eby’omurembe ebirikuhikaana n’ebyetengo byawe.
