Inzira yo kumurika hamwe nuburyo bwo gusiga byombi biri mubyiciro byoherejwe nyuma yo gucapa kurangiza gutunganya ibintu byacapwe. Imikorere yabyo irasa cyane, kandi byombi birashobora kugira uruhare runini mugushushanya no kurinda ubuso bwibintu byacapwe, ariko hariho itandukaniro hagati yibi:
Kurangiza
Kurangiza ubuso nugukora gutunganya neza hejuru yibintu byacapwe kugirango urusheho guhangana n’umucyo, kurwanya amazi, kurwanya ubushyuhe, kurwanya ubukana, kwambara no kurwanya imiti y’ibikoresho byacapwe; kongera ububengerane hamwe nubuhanzi bwibintu byacapwe; kandi urinde ibintu byacapwe. N'umurimo wo kurimbisha ibintu byacapwe no kongera agaciro k'ibintu byacapwe. Uburyo busanzwe bwo guhindura ibintu kubintu byacapwe birimo gusiga, kumurika, kubeshya, gupfa, gukata cyangwa gutunganya ibindi.
01 ibisobanuro
Kumurikani nyuma yo gucapa aho firime ya pulasitike isize hamwe yometseho hejuru yikintu cyacapwe. Nyuma yo gushyushya no kuvura igitutu, ibintu byacapwe na firime ya pulasitike byahujwe cyane kugirango bibe ibicuruzwa byahujwe na plastiki. Inzira ya laminating ni iyimpapuro-plastike ikomatanya murwego rwo guhuza kandi ni yumye.
Glazing nuburyo bukoreshwa murwego rwo gusiga irangi ridafite ibara risobanutse (cyangwa ryatewe cyangwa ryacapwe) hejuru yikintu cyacapwe. Nyuma yo kuringaniza no gukama (calendering), hakeye kandi hakeye hakeye harabagirana hejuru yibintu byacapwe. Inzira irimo gutwikira (bakunze kwita inzira yo gukoresha langi (harimo resin ikora firime, ibishishwa hamwe ninyongeramusaruro) hejuru yibintu byacapwe kugirango bingane kandi byume.
02 Imikorere nubusobanuro
Nyuma yubuso bwibintu byacapwe bitwikiriwe nigice cya firime ya pulasitike (coating) cyangwa igasiga irangi ryirangi ryirangi (glazing), ibintu byacapwe birashobora gukorwa kugirango bigire imirimo yo kurwanya ubukana, kutagira amazi, kutagira amazi na anti-fouling, nibindi, ntibirinda gusa ibyacapwe, ahubwo binarinda ibintu byacapwe. Kwagura serivisi zubuzima bwa serivisi, binatezimbere ubwiza bwubuso bwibintu byacapwe, byongera agaciro ka imitako, bituma ibishushanyo byacapwe hamwe ninyandiko igaragara neza mubara, kandi bigira ingaruka zikomeye ziboneka, bityo bikazamura ubwiza bwibicuruzwa no kongera agaciro kongerewe. Kurugero, ibitabo bitwikiriye lamination, hejuru yububiko bwamavuta yo kwisiga, nibindi.
Kubwibyo, kumurika no gusiga ni bumwe muburyo bwingenzi bwo gutunganya ibintu nyuma yo gucapa hejuru yo kurangiza ibintu byacapwe. Ntibishobora "kumurika" gusa hejuru yibintu byacapwe no gukurura abakiriya, ariko kandi birinda ibintu byacapwe no kunoza imikorere. Ubu birakoreshwa cyane. Irakwiriye gushushanya hejuru yibitabo, ibinyamakuru, alubumu y'amashusho, inyandiko zitandukanye, udutabo twamamaza no gushushanya hejuru y'ibicuruzwa bipakira impapuro.
03 Inzira iratandukanye
Igikorwa cyo gutwika amafirime Igikorwa cyo gutwikira firime gishobora kugabanywa muburyo bwa tekinoroji ya firime hamwe nubuhanga bwa firime mbere yo gutwikira ukurikije ibikoresho fatizo nibikoresho byakoreshejwe.
1)firime Banza ikoresha igikoresho cyo gutwikisha uruziga kugirango iringanize neza hejuru ya firime ya plastiki. Nyuma yo kunyura mu gikoresho cyo kumisha, ibishishwa mu bifata bigahumuka, hanyuma ibintu byacapwe bikururwa ku gikoresho gishyushye gikanda. Kuri mashini ,.firimekandi ibintu byacapwe bikanda hamwe kugirango birangize lamination no gusubira inyuma, hanyuma bibikwa kubishusho no kunyerera. Ubu buryo bukoreshwa cyane mubushinwa. Urebye ibikoresho bifata bikoreshwa muri firime yo gutwikira, birashobora kugabanywamo firime ishingiye kumashanyarazi hamwe na firime ifata amazi.
2) Filime mbere yo gutwikira Igikorwa cya firime ibanziriza gutwikira ni iy'abakora umwuga babigize umwuga mbere yo kubara no kuringaniza ibifata kuri firime ya pulasitike, byumye, gusubiza inyuma, no kubipakira mu bicuruzwa bigurishwa, hanyuma ibigo bitunganya bikabishyiraho ibifuniko bidafite amavuta. Gukanda bishyushye bikorwa kubikoresho byo kumurika igikoresho kugirango urangize inzira yo kumurika ibintu byacapwe. Ibikorwa bya firime mbere yo gutwika byoroshya cyane uburyo bwo gutwikira kuko ibikoresho byo gutwikira ntibisaba sisitemu yo gushyushya no gukama, kandi byoroshye gukora. Muri icyo gihe, nta guhindagurika gukabije kandi nta guhumana kw’ibidukikije, biteza imbere imikorere; icy'ingenzi cyane, ni Kubaho gutwikiriye ubuziranenge kunanirwa nkibibyimba no gusiba biririndwa rwose. Ubucucike bwibicuruzwa bisize ni hejuru cyane. Ugereranije nuburyo busanzwe bwo gutwikira, bufite uburyo bwagutse bwo gusaba.
1) Amashanyarazi ashingiye Amashanyarazi ashingiye kumashanyarazi bivuga uburyo bwo gusiga bukoresha benzene, esters na alcool nkibishishwa hamwe nubushyuhe bwa thermoplastique nkibisumizi. Mugihe cyo kumurika, ibishishwa bigenda byuka hanyuma resin polymerize cyangwa reaction ihuza reaction ikora firime. Irangwa nishoramari ryibikoresho bito nigiciro gito, ariko guhindagurika kwa solvent hamwe nibisigara kubintu byacapwe bizatera umwanda ibidukikije kandi byangiza umubiri wumuntu.
2) Gusiga amazi Amashanyarazi ashingiye kumazi nuburyo bwo gusiga bukoresha ibishishwa byamazi cyangwa ubwoko butandukanye bwibisaranganya amazi nkibintu bikora firime. Irangi rishingiye ku mazi rikoresha amazi nk'igishishwa, kandi nta kintu kama gishobora guhinduka mugihe cyo gutwika no gukama. Ikiranga ni uko uburyo bwo gusiga butagira impumuro mbi, nta kwanduza ibidukikije, kandi ntacyo byangiza umubiri w'umuntu. Ikoreshwa cyane mu gupakira itabi, imiti, ibiryo, amavuta yo kwisiga n'ibindi bicuruzwa.
3) UV glazing UV glazing ni ultraviolet imirasire yumye. Ikoresha imirasire ya ultraviolet kugirango imurikire amavuta yaka kugirango ihite itera reaction ya fotokimike yamavuta yamavuta kugirango ibe igifuniko cyiza gifite imiterere yimiti ya neti hejuru yikintu cyacapwe. Uburyo bwo gukiza glazing nuburyo bumwe bwo gukama wino ya UV. Irangwa nuburabyo bwiza, ubukana bukabije nubushyuhe bwo kwambara, gukama vuba, umutekano no kurengera ibidukikije. Ifite iterambere ryisoko ryagutse. Kimwe n'amazi ashingiye kumazi, akoreshwa cyane mubuvuzi, ibiryo, nibindi bipfunyika ibicuruzwa mumurima.
