Lamination

Melamine yahuye nanone nanone yitwa intebe igezweho hamwe nibara cyangwa imiterere itandukanye. Medilamine Impapuro zidacometswe kumwanya ushingiye ku giti gishingiye kuri MDF, Inama Nkuru, Plywood, akanama gake, hanyuma ikamanura ubushyuhe bwinshi kandi umuvuduko ukabije ufite ibibazo byinshi. Ubuso bwa Memilamu bushobora kunoza imbaraga gusa, gukomera no gushikama kwayo, ariko nabyo birashobora gutuma ubuso bwa kwambara bwo kwambara, kurwanya ubushyuhe bwo kurwanya ibidukikije, ubuzima n'imikorere.

Ibikorwa byateganijwe PRINELS: Gutegura Panels → Ipane nziza → Meneline School impapuro → Kubura Gusohoza → Igenzura → Ububiko → Ububiko → Ububiko. Mbere yo kumara, tugomba guhitamo akabati keza k'ibiti hamwe na melamine bidashingiye ku mpapuro, gusa ibikoresho by'ubushobozi byonyine byatoranijwe kugira ngo umusaruro.

Impapuro zidahwitse zisaba ibirimo resin ni 130 - 150%, ibirimo bihindagurika 6 - 7%, icyiciro cyambere cyo gukira ≦ 65%. Melamine Impapuro zidacogora zigomba kuba zimeze neza, kandi zuzuye hamwe na firime kugirango wirinde kwinjiza ubushuhe. Nibyiza kuramba mbere y amezi 3 nyuma yumusaruro, kandi ukabikwa mububiko hamwe nubushyuhe bugereranije bwa 60 + 5%, ubushyuhe 20 - 25 ℃. Parike izwi cyane ni ikibaho cya fibre, ikigo cyinama na plywood. Ibisabwa kugirango bisabwa: 1) Umusenyi wa kabiri, ubuso buroroshye kandi bwaka, bumwe, ubunini bwo kwihanganira 0.2mm. 2) Impande zumuyobozi ntizimye, ntizirya, nta mwanda wa peteroli cyangwa amazi. 3) Ibirimo byubushuhe byubuyobozi bigenzurwa murwego rwa 6 - 10%.

Mugihe cyo kubura, tugomba gukurikiza byimazeyo ibisobanuro bya tekiniki, kugenzura ubushyuhe 140 - 190 ℃, igice cy'umuvuduko 2.0 - 3.0MPA, igihe cyo gukanda 25 - 50s. Igihe cyo gukanda ubushyuhe, igihe cyo gukanda no gukanda ni urwangwe kandi kikabujijwe, kikaba gishobora guhinduka ukurikije urukundo rwinshi rwibasiwe. Ubushyuhe bushyushye cyane cyane bwihutisha cyane reaction ya melamine resin, ubushyuhe bukora cyane ni 140 - 190 ℃. Ubushyuhe bwo hejuru burashobora gufasha kurekura nyuma yitangazamakuru, kandi birashobora kunoza imikorere yumusaruro.ariko ubushyuhe bwinshi buzatuma resin gukiza mbere yimyenda imwe. Umuvuduko ukwiye urashobora kwemeza amarangamutima meza hagati yimbaho n'impapuro zidashoboka, igitutu gikora muri rusange 2.0 - 3.0MPA, kiba cyiza kuri resin, gikora ubuso bufunze kandi bufunze. Munsi yubuziranenge bwiza, igitutu gito kigomba gukoreshwa mugupima ubuzima bwa serivisi yibikoresho, kandi nibyiza kumiterere yimbere. Ariko igitutu gito cyane kizagira ingaruka ku mbaraga zifatika no kubushobozi bwo gutanga. Ukurikije ubwoko butandukanye bwa panels, igitutu cyigice gikeneye guhindurwa na buffer. Igihe cyo gukanda biterwa numuvuduko wo gukiza wa resin mu mpapuro zidasanzwe hamwe n'ubushyuhe bwo gukanda, naho 25 - 50s nibyiza. Igihe kirangiye cyane kizatera resin gukira kandi ugatakaza elastike, bikavamo igikoma cyangwa mubikorwa cyangwa muburyo bukurikira bizazana igikoma, kurwana. Igihe ni gito cyane, resin gukira ntigihagije, kora imbaho zifata kandi zigira ingaruka ku kuramba.

Isesengura ryinzobere zisanzwe zinze ubumwe nimpamvu zateganijwe mbere:

1) Ahantu hera, impamvu nyamukuru nuburyo bubi bwimpapuro zidasobanutse cyangwa ibirimo bike. Impamvu zishobora kuba: Nta musenyi ku butaka cyangwa umusenyi ntabwo ari imyenda, aho ubushyuhe bukabije bwo kwiheba, hanyuma bikaba birusheho kwiheba. SHAKA Ibirimo byinshi cyane kuri Melamine Impapuro zidacogora zishobora kuzana igituba mugihe cyo kumara amatara kandi gitera ahantu hera.

2) Ahantu hatose, bivuga ibimenyetso byimbaho bikozwe hejuru, kandi hari inenge zigaragara ni izindi mpande zabashitsi.

3) gukomera hamwe nisahani yicyuma bivuga inkoni yo muri Memilamu na plate yicyuma mugihe cyo kumara amatara. Gukomera gato bizagira ingaruka kumiterere yubuso, gukomera cyane bizahindura umusaruro Ibirimo byinshi bihindagurika byimpapuro zidasanzwe, ubushyuhe buke bwo gukanda hamwe nigihe gito cyo gukanda, bikavamo gusiba ntibyari gukira neza. Ibyangiritse kuri mat bivamo ntabwo ari ubushyuhe bumwe kuri plate yicyuma bizasohora. Ibirimo byinshi cyangwa agaciro ka PH ku mbaho bizana kurekurwa nabi.

4) Bubbles, impamvu nyamukuru: ubushyuhe bwinshi cyane bwo gukanda, igihe kinini cyo gukanda kizana demix cyangwa ibituba. Ubushuhe buke cyane cyangwa bunamiye cyane birashobora kuzana demix cyangwa ibituba mugihe cyo kumara ingano.

5) Inyenzi zijimye zivuga hejuru cyangwa gukata kunama kubera uburinganire bubi bwimbaraga zimbaraga. Impamvu nyamukuru ni: Itandukaniro rinini mugukanda ubushyuhe hagati yisahani yo hejuru no hepfo itera umuvuduko utandukanye kandi uganisha ku muheto. Medilamu zitandukanye zidacometse ku butaka zombi zishobora gutera kunyerera nyuma y'ibinyoma.Niba ikibaho gishyushye cyashyizwe kuri un - pallets, irashobora gutera.

Muri make, tugomba guhitamo impapuro zidasanzwe hamwe nimbaho nziza - Itsinda rishingiye ku bikoresho bibisi, no kunoza inzira yo gukora ibikoresho bitandukanye, ku bufatanye bw'ibikorwa n'ibikoresho byo kubyaza umusaruro, ku bufatanye bw'ibikorwa n'igenzura, bishobora kwemeza umutekano w'ibicuruzwa.
