Ikibaho cya Melamine nacyo cyitwa prelaminated panel ifite ibara cyangwa imiterere itandukanye. Impapuro zatewe na Melamine zashyizwe ku mbaho zishingiye ku biti nka MDF, ikibaho cy'ibice, pani, ikibaho, hanyuma bigashyirwa hamwe n'ubushyuhe bwinshi n'umuvuduko mwinshi. Urupapuro rwa melamine ntirushobora gusa kunoza imbaraga zumwanya, gukomera no guhagarara neza, ariko kandi rushobora gutuma ubuso bwarwo bufite ibyiza byo kurwanya kwambara, kurwanya ubushyuhe bwinshi, kurwanya umwanda, kurengera ibidukikije, ubuzima n’imikorere.
Ikibaho cyateguwe mbere: Gutegura ibibaho → Ikibaho gisukuye → Melamine Impapuro zatewe → Kumurika → Gusubiramo → Kugenzura → Ububiko. Mbere yo kumurika, tugomba guhitamo ibiti byo mu rwego rwo hejuru bishingiye ku mbaho hamwe n'impapuro zatewe na melamine, gusa ibikoresho byujuje ibyangombwa byashoboraga gutorwa kugira ngo bibyare umusaruro.
Impapuro zinjijwe zisaba ibirimo resin ni 130-150%, ibintu bihindagurika 6-7%, impamyabumenyi yo gukiza ≦ 65%. Impapuro zatewe na Melamine zigomba kuba zimeze neza, kandi zuzuyemo firime kugirango wirinde kwinjiza amazi. Nibyiza kumurika mbere y amezi 3 nyuma yumusaruro, ukabikwa mububiko hamwe nubushyuhe bugereranije bwa 60 + 5%, ubushyuhe 20-25 ℃. Ikibaho kizwi cyane ni fibre ikibaho, uduce duto na pande. Ibisabwa byubuziranenge bisabwa: 1) kumusenyi wimpande ebyiri, hejuru iroroshye kandi irasa, uburebure bumwe, kwihanganira umubyimba 0.2mm. 2) impande zibaho ntizihagije, ntabwo zirya, nta mavuta cyangwa umwanda uhumanya. 3) ibirimo ubuhehere bwibibaho bigenzurwa murwego rwa 6-10%.
Mugihe cyo kumurika, tugomba gukurikiza byimazeyo ibisobanuro bya tekiniki, kugenzura ubushyuhe bwo gukanda 140-190 ℃, umuvuduko wibice 2.0-3.0MPa, gukanda 25-50s. Kanda ubushyuhe, igitutu nigihe cyo gukanda biraterana kandi birabujijwe, bishobora guhinduka ukurikije urukundo nyarwo rwabanyamakuru. Ubushyuhe bushyushye cyane cyane kwihutisha imiti ya melamine resin, ubushyuhe bukora cyane ni 140-190 ℃. Ubushyuhe bwo hejuru burashobora gufasha kurekura nyuma yo gukanda, kandi burashobora kugabanya igihe cyo gukanda, kunoza imikorere yumusaruro.Ariko ubushyuhe bwinshi cyane buzatuma resin ikira mbere yimigezi imwe, itera ibinure hejuru yubuyobozi. Umuvuduko ukwiye urashobora kwemeza neza gufatana hagati yimbaho nimpapuro zatewe, igitutu gikora ni 2.0-3.0MPa, kikaba cyiza kubishonga bigashonga kandi bigakomera, bigakora ubuso bufunze kandi bworoshye. Hishimikijwe ubuziranenge bwiza, umuvuduko muke ugomba gukoreshwa kugirango wongere igihe cyakazi cyibikoresho, kandi ni ingirakamaro kumiterere yimbere yingurube. Ariko umuvuduko muke cyane uzagira ingaruka kumbaraga zifatika hamwe nubushobozi bwa resin. Ukurikije ubwoko butandukanye bwibibaho, igitutu cyibice bigomba guhindurwa na materi ya buffer. Igihe cyo gukanda giterwa n'umuvuduko ukiza wa resin mu mpapuro zatewe hamwe n'ubushyuhe bwo gukanda, kandi 25-50s nibyiza. Igihe ni kirekire cyane bizatera resin gukira birenze urugero no gutakaza elastique, bikavamo gucika cyangwa imbere mubushake kandi muburyo bukurikira bizazana gucika, kurwana. Igihe ni gito cyane, resin gukira ntabwo ihagije, kora imbaho zifatika kandi zigire ingaruka kubicuruzwa biramba.
Isesengura ryinenge zisanzwe hamwe nimpamvu zitera paneli:
1) Ikibanza cyera, impamvu nyamukuru ni ukugenda nabi kwimpapuro zatewe cyangwa ibintu bike bya resin. Impamvu zishobora kuba: nta mucanga hejuru yubutaka cyangwa umusenyi ntabwo ari kimwe, aho ubucucike buri hasi, bikavamo ubwinshi bwimyunyu ngugu muri kariya gace, kandi bikazana umuvuduko mubi wa resin utera ibibara byera. Kwiheba cyane mubice bimwe na bimwe, kandi umuvuduko ntuhagije muri utwo turere mugihe cya lamiantion, kandi uzane umuvuduko mubi wa resin, hanyuma utere ikibara cyera.Ubushyuhe bwinshi, hamwe numuvuduko ukabije, hamwe nicyapa cyanduye gishobora kugira ingaruka kumyanda, hanyuma bigatera ikibara cyera.Ibyangiritse byangiza, biganisha ku bushyuhe butandukanye kumwanya utandukanye wibyuma kandi bigatera ikibara cyera.Ububiko bwigihe cyo kubika impapuro zatewe na melamine, impamyabumenyi yo hejuru yo gukira, cyangwa hasi cyane agaciro ka PH kumabaho, bizagira ingaruka kumyanda kandi bitera ikibara cyera. Ibirungo byinshi cyane kuri melamine yatewe impapuro zishobora kuzana ibibyimba mugihe cyo kumurika kandi bigatera ikibara cyera.
) gukanda ubushyuhe cyangwa kurasa igihe cyo gukanda, byoroshye kugaragara ahantu hatose. Ibirungo byinshi biri hejuru kubibaho biganisha ahantu hatose mugihe cyo kumurika.
3) Kwizirika ku isahani yicyuma bivuga inkoni ya melamine hamwe nicyapa mugihe cyo kumurika. Gufata gahoro bizagira ingaruka kumiterere yubuso, gufatana uburemere bizagira ingaruka kumusaruro.Impamvu nyinshi ni: ibirimo resin nyinshi cyangwa icyuma cyanduye, biganisha kurekurwa nabi. Ibintu byinshi bihindagurika byimpapuro zatewe, ubushyuhe buke bwo gukanda nigihe gito cyo gukanda, bivamo resin ntabwo yakize neza kugirango irekurwe nabi. Ibyangiritse ku matati bivamo ubushyuhe butari bumwe ku isahani izana kurekura nabi. Ibirungo byinshi cyangwa agaciro ka PH hejuru kubibaho bizana kurekura nabi.
4) Ibibyimba, impamvu nyamukuru: ubushyuhe bukabije bwo gukanda, igihe kinini cyo gukanda kizana demix cyangwa ibituba. Ubushuhe bukabije cyangwa buto cyane bwibibaho birashobora kuzana demix cyangwa ibibyimba mugihe cyo kumurika.Ubucucike buke butera demix cyangwa ibibyimba.
5) Gukubita umuheto bivuga ubuso butaringaniye cyangwa gukata kunama kubera uburinganire bubi bwimbaraga zimbere. Impamvu nyamukuru nizo: Itandukaniro rinini mukanda ubushyuhe hagati yicyuma cyo hejuru nicyuma gitera umuvuduko ukiza kandi biganisha kumuheto. Impapuro zitandukanye za melamine zatewe ku mpande zombi zishobora gutera kunama nyuma yo kumurika.Niba imbaho zishyushye zashyizwe hejuru zipakiye kuri pallets zidafite igorofa, zishobora gutera kunama.
Muri make, tugomba guhitamo impapuro nziza zatewe hamwe nibiti bishingiye ku biti nkibikoresho fatizo, kandi tugahindura uburyo bwo kubyaza umusaruro nkibikoresho bitandukanye bitanga umusaruro, ku bufatanye n’ibikorwa n’abashinzwe kugenzura, bishobora kwemeza ireme ry’ibicuruzwa.
