1) Igishusho cyiza cya pisine nicyuma cyakozwe numuntu gikozwe mubiti bisanzwe bikozwe mubiti bikozwe mubiti bifatanye na pani.Imitako ishushanya ni igiti gito cyane gikozwe mu giti cyiza binyuze mu gutegura cyangwa gukata kuzunguruka
2) Ibiranga pisine nziza yo gushushanya:
Imyenda ya pisine ya pisine nimwe mubikoresho bikoreshwa cyane mugushushanya imbere.Bitewe nuko icyuma gishushanya hejuru yiki gicuruzwa gikozwe mu biti byo mu rwego rwo hejuru binyuze mu gutegura cyangwa gukata kuzenguruka, bifite imikorere myiza yo gushushanya kuruta pani.Ibicuruzwa bisanzwe biroroshye, karemano kandi byiza, kandi birashobora gukora ibidukikije byiza kandi bifite ubuzima bwiza kubantu.
3) Ubwoko bwa pisine yo gushushanya:
Imyenda ishushanya irashobora kugabanywamo ibice bimwe byo gushushanya no gushushanya impande zombi ukurikije imitako;Ukurikije uko irwanya amazi, irashobora kugabanywa mucyiciro cya mbere cyo gushushanya icyuma cya pisine, icyiciro cya kabiri cyo gushushanya icyuma cya pisine, na pisine yo mu cyiciro cya III;Ukurikije imiterere yimyenda ishushanya, irashobora kugabanywamo ibice byo gushushanya bya radiyo na chord decorative veneer.Igisanzwe ni uruhande rumwe rwo gushushanya imitwe ya pande.Ubwoko bwibiti bukoreshwa muburyo bwo gushushanya burimo ibishishwa, ivu, igiti, elm, maple, walnut, nibindi.
4) Itondekanya rya pisine ishushanya:
Igipimo cyerekana amashanyarazi meza yo mu Bushinwa giteganya ko pani yo gushushanya igabanijwemo ibice bitatu: Ibicuruzwa byiza, ibicuruzwa byo mu rwego rwa mbere nibicuruzwa byujuje ibyangombwa.Ibi byibutsa ababikora n’abaguzi ko ubundi buryo bwo gutanga amanota butubahiriza ibipimo by’Ubushinwa kuri pisine nziza.Kurugero, ababikora bamwe bafite ikirango cyurwego rwa "AAA", nimyitwarire yumuryango.
5.Ibipimo ngenderwaho byerekana ibipimo byerekana amashusho ya pisine muburyo bwiza bwo kugaragara, gutunganya neza, hamwe nuburyo bwimiterere nubukanishi.Ibipimo byumubiri nubukanishi birimo ibirimo ubushuhe, imbaraga zo guhuza hejuru, hamwe no kwibiza.GB
Standard Igipimo cyigihugu giteganya ko ibipimo byubushuhe bwa pisine ya pisine ishushanya ari 6% kugeza 14%.
Strength Imbaraga zo guhuza ubuso zigaragaza imbaraga zo guhuza hagati yicyubahiro cya veneer layer na pande substrate.Igipimo cy’igihugu giteganya ko iki kimenyetso kigomba kuba ≥ 50MPa, naho umubare w’ibizamini byujuje ibisabwa ugomba kuba ≥ 80%.Niba iki kimenyetso kitujuje ibyangombwa, byerekana ko ubuziranenge bwo guhuza hagati yimyenda ishushanya na pisine ya substrate ikennye, ibyo bikaba bishobora gutuma urwego rwimitako rufungura kandi rukabyimba mugihe cyo gukoresha.
Pe Gukuramo ibibyimba byerekana imikorere ihuza buri cyiciro cya pisine ishushanya.Niba iki kimenyetso kitujuje ibyangombwa, byerekana ko ubuziranenge bwubuyobozi bwifashe nabi, bushobora gutera gufungura mugihe cyo gukoresha.
Limit Imipaka yo kurekura.Iki kimenyetso ni igipimo cy’igihugu giteganijwe gushyirwa mu bikorwa n’Ubushinwa ku ya 1 Mutarama 2002, aricyo "uruhushya rwo gukora" ku bicuruzwa bifitanye isano.Ibicuruzwa bitujuje ubuziranenge ntibyemewe kubyazwa umusaruro kuva ku ya 1 Mutarama 2002;Iki kandi ni "icyemezo cyo kubona isoko" kubicuruzwa bifitanye isano, kandi ibicuruzwa bitujuje ubuziranenge ntibyemewe kwinjira mumasoko azenguruka isoko kuva ku ya 1 Nyakanga 2002. Kurenga urugero rwa fordehide bizagira ingaruka kubuzima bwabakoresha.Igipimo giteganya ko imyuka ya formaldehyde ya pisine ya pisine igomba gushushanya: E0level: ≤0.5mg / L, E1 urwego ≤ 1.5mg / L, E2 urwego ≤ 5.0mg / L.
Guhitamo
Mu gukora pani, havutse ubwoko bwinshi bwibishushanyo namabara, muribyo byingenzi cyane nukugumisha urwego ruto rwimyenda yo gushushanya hejuru ya pani yumwimerere, izwi nka pisine ya pisine, mu magambo ahinnye nkibibaho byo gushushanya cyangwa akanama gashushanya isoko.
Birakwiye ko tumenya ko imbaho zisanzwe zishushanya zigabanyijemo imbaho zisanzwe zimbaho zimbaho zimbaho hamwe nimbaho zoroshye zo gushushanya ibiti.Igiti gisanzwe cyibiti nigituba cyoroshye gikozwe mubiti bisanzwe byigiciro binyuze mugutegura cyangwa gutunganya kuzenguruka.Ibikoresho byubukorikori ni imitako ishushanya ikozwe mu biti bihendutse bihendutse, ikazunguruka ikagabanywa mu mbuga zimbaho binyuze mu nzira runaka yo gufunga no gukanda.Hanyuma irategurwa hanyuma igabanywa muburyo bwo gushushanya hamwe nibishusho byiza.
Mubisanzwe, ibiti bisanzwe bikozwe mubiti bishushanyijeho imitako ishushanya ifite ishusho nziza nagaciro gakomeye, nka cypress, igiti, igiti cyitwa rosewood, nivu.Ariko, bigomba gusobanurwa mwizina ryibicuruzwa, nka "cypress veneer plywood", "ivu ryamazi yaciwe pani", cyangwa "Cherry wood veneer".Ibintu byingenzi biranga "ikibaho cyo gushushanya" bigaragarira muburyo butandukanye bwo kwita izina nka "veneer", "gukata", na "ikibaho cyo gushushanya".Ariko, ntishobora kuvugwa mu ncamake nka pisine ya cypress cyangwa pisine y'amazi, kuko aya magambo ahinnye yerekeza ku mbaho za pani na plaque yo hepfo ikozwe muri cypress cyangwa ivu ryamazi.Ikindi kibazo nuko umusaruro wibikoresho bifite imbaho zishushanya wiyongera.Nubwo ibi bikoresho bishobora kuba bifite "ibiti bya cypress" cyangwa ibindi binyampeke byimbaho, ibiti rusange bikoreshwa mubikoresho bikozwe mubindi biti.Muri iki gihe, amaduka yanditseho ibi bikoresho “
Ingingo z'ingenzi zo guhitamo
1) Hitamo ubwoko butandukanye, amanota, ibikoresho, imitako, nubunini bwa pani ukurikije ibintu nkibikoresho byubwubatsi, aho bikoreshwa, nibidukikije.
2) Umutako ugomba gukoresha ibiti byagaciro hamwe na veneer yoroheje
3) Amashanyarazi akoreshwa mu gushariza imbere mu nyubako agomba kubahiriza ibivugwa muri GB50222 "Kode yo gukingira umuriro yo gushushanya imitako y’imbere mu nyubako."
4) Ibice byihishe bishobora kwibasirwa nubushuhe nibihe bisabwa cyane bitarinda amazi bigomba gutekereza gukoresha pisine yo mucyiciro cya mbere cyangwa icyiciro cya kabiri, naho pani yo mucyiciro cya mbere igomba gukoreshwa mugukoresha hanze.
5) Imitako yimbaho isaba gukoresha lanike ibonerana (izwi kandi nka varish) kugirango ibungabunge ibara karemano hamwe nimiterere yibiti.Hagomba gushimangirwa ku guhitamo ibikoresho, imiterere, n'amabara;Niba igishushanyo n'amabara yibibaho bidakenewe gusuzumwa, urwego nicyiciro cya pani nabyo bigomba guhitamo neza ukurikije ibidukikije nigiciro.
