Melamine

Melamine Impapuro zidacogora, koresha imico yo mu rwego rwo hejuru yacapwe, yatewe na Melamine resin, hanyuma ukemuke ku bwoko bwose bw'ibiti bishingiye ku giti. Ifite ingaruka nziza nziza cyane hejuru yimbeho, hanyuma ugire ubuhanga bwo kurwanya ubushyuhe bwinshi, wambare - umwanda urwanya no kurwanya.

Kugeza ubu kudasiba mubisanzwe bifata ibyuzuye kabiri. Impapuro zamaboko zabanje guterwa hamwe na melamine isanzwe kugirango ubone urwego rwibanze, hanyuma ukoreshe Melamine Urwego rwa kabiri Gutagira inkingi bifite ibisabwa kumpapuro zacapwe na Melamine resin. Resin nyuma yo guhindura igomba kubona guhinduka, bishobora kubuza ubuso bwaka. Mu musaruro nyacyo, Melamine Resin nawe akeneye kongeramo inyongeramuco zitandukanye.

Mu rwego rwo kwemeza ireme rya Mecholamine ritajyanye n'impapuro zidasanzwe, impapuro zo gushushanya ubuziranenge zigomba gukoreshwa. Impapuro zo gushushanya ntizifite α pulp fibre, ikora neza mumabara, kandi irwanya ubushyuhe bwinshi bwa 180 c, nubwumvikanyi bwiza. Mubisanzwe Gramboge yimpapuro zimpapuro zigomba kuba 70 - 90G / ㎡, hamwe no kwihanganira ± 2g / ㎡, Ibirimo Ubushuhe 2.5 - 4. 7.5. Niba agaciro ka PH biri hasi cyane, birashobora kunyeganyega mugihe cyo kudahinduka. Kugira ngo wirinde gucamo mugihe cyo kudahinduka, uburebure bwikiruhuko kirekire butose byibuze 450m, hamwe na 300m. Kugirango ubone umuvuduko mwiza, impapuro zaciwe zigomba kugira cyane cyane hamwe no kwinjira byihuse. Ibisabwa n'amazi bisabwa: Vertical 25 - 35mm / min, horizontal 22 - 30m / min. Kuringaniza impapuro zamatako bigomba kuba bishyize mu gaciro, hasi cyane birashobora kugira ingaruka ku mazi hejuru kandi hejuru cyane bizagabanya ubushobozi bwo gutanga umusaruro.

Modulation resin ahanini ni MF na UF, kimwe ninyongeramuco zitandukanye. Gukiza oxitive bigira uruhare rwa catalyst kugirango wihutishe igihe cyo kurengana mugihe cyo kubura. Gutobora no kugabanya imitingi ya resin, no kuzamura ubushobozi bwinjira kumpapuro zo gushushanya kugirango wemeze uburinganire bwo kudahinduka. Kurekura ibiyobyabwenge bikoreshwa mu gukumira impapuro zidahwitse ku isahani y'icyuma mugihe cy'ubujurire Solven ni amazi cyangwa ethanol, yatandukanije vicosity kugirango ibone ibyiza byinshi kumpapuro. Gukoresha tekinoroji idasanzwe ya glue kugirango uhindure melamine formaldehyde resin na urea formaldehyde resin, hanyuma wongereho asizwe, utobora inyongeramuke, zirimo kwiyuhagira. Nyuma yo kutagira intangarugero inshuro ebyiri, impapuro zo gushushanya zigomba gukama, zikonje kandi zikata mubunini bumwe. Ingano isaba kuba hafi 10 - 30Mm nini kuruta imbaho z'ubugari n'uburebure Hamwe no kwemezwa, melamine yarangije impapuro zigizwe zishobora guhuzwa na firime ya polyethylene. Impapuro zigera kuri 200 kuri Bale, 10 bales buri pallet. Kugirango tumenye amatara meza, Melamine Impapuro zidacogora zigomba kubikwa muburyo bwiza. Ubushuhe ugereranije mububiko ni 60 ± 5%, kugirango impapuro zitazakurura cyangwa kurekura ubushuhe. Ubushyuhe bugomba kuba 20 - 25 ℃. Ubushyuhe bwinshi nubushuhe buke butuma impapuro zimpapuro zidasanzwe ziba byoroshye kandi zifata. Ariko impapuro zidacogora biroroshye guca igihe ubushyuhe buciriritse. Ubuzima bubi bwimpapuro zidasobanutse ni amezi 3 nibabitswe neza. Kugirango wirinde gukomera kubera kwikuramo ubushuhe, nyamuneka subiza kandi kashe kamaze gufungura.

Ibirimo bidasanzwe (bikomeye cyane ugereranije n'uburemere bwa resin) ni 130 - 150%. Ibirimo byo hasi bizana imbaraga nke kurupapuro, kandi biroroshye kuri dimex. Ibikubiyemo bikwiye ni byiza kumara kunera mumusaruro nubwiza. Iyo ibisigaye biri hejuru cyane, biroroshye kurakara. Ibirimo byihuta (saa 160 ℃ Kuma iminota 10) yari 6 - 7%.
