Ivyuma bifatanya birafise uruhara runini mu guhingura no gukora neza ibintu vy’ibiti vy’ubuhinga. Kuva ku mbaho ​​z’ibiti n’ivy’ibara ry’agahama gushika ku mbaho ​​za MDF, OSB, n’ibipande vy’ibipande,uburyo bwo kwifatanya ni bwo bugena inkomezi z’ubuhinga, uburemere, ukuntu bushobora guhangana n’ubukonje, n’umutekano w’ibidukikije vy’igicuruzwa ca nyuma.

Mu bijanye n’ubuhinga bw’ibiti bwo muri iki gihe, uguhitamwo ivyuma bifatanya ni kimwe mu bintu bihambaye cane bigira ico bikoze ku buryo ibintu bigenda neza no ku bijanye n’uguhiganwa kw’isoko. Iki kiganiro kiratanga inyishu yuzuye y’ubuhinga ibereye abaguzi b’inganda, abahinguzi be n’abahinga mu vy’ubwubatsi.

1. Kubera iki ivyuma bifatanya bifise akamaro mu bipande vy’ibiti

Ivyuma vy’ubuhinga vyishingikiriza ku bintu bifatanya kugira ngo bibohe ibipande vy’ibiti, intsinga canke ibihimba bimwebimwe kugira ngo bibe ikintu kimwe. Ivyuma bifatanya bifasha:

1.1 Ibikorwa vy'ubuhinga

Inkomezi z'ubufatanye bw'imbere

Module y'uguca

Uguhangana n'uguhinduka canke ugusenyuka

1.2 Gushikama kw'ingero

Imbaho ​​zishikirwa n’ingendo z’ubukonje zishingiye cane ku vyo kwifatanya kugira ngo zigume ziringaniye kandi zidakomeretse.

1.3 Ugukomera no guhangana n'ugukura

Ivyuma bifatanya bikora cane-bishobora kunanira ubushuhe, ubukonje, n'ugusenyuka kw'ibinyabuzima.

1.4 Umutekano w'ibidukikije

Ivyo bihimba vy’umubiri bita formaldehyde biva ahanini ku bintu bifatanya, ntibiva ku giti ubwaco.

Rero,ubuhinga bwo gukora ivyuma bifatanya n'ubuhinga bwo gucapura bishushe bigena neza ingero z'ibidukikije mu gihugu no kw'isi yosenk’ivyo E1, E0, CARB, EPA TSCA Umutwe VI, n’Ubuyapani F★★★★.

2. Ubwoko buhambaye bw'ibifatanya mu nganda y'ibiti

2.1 Ureya Formaldehyde Resini (UF)

Ivyuma bifatanya UF nivyo bikoreshwa cane kubera:

Igiciro gito

Gukira vuba

Uguhuza n'uguhingura MDF n'ibipande vy'ibipande

Ariko rero, UF irafise aho igarukira:

Birimwo formaldehyde

Bishobora gushikirwa n'ubukonje

Gushikama kw'igihe kirekire -

Ibikoresho bikunze gukoreshwa ni MDF, ivyuma vy'ibipande, n'ibiti vy'ibipande vy'ibiciro bito-.

2.2 Igikoko citwa melamine

MUF ni UF yongeweko melamine kugira ngo itere imbere:

Uguhangana n'amazi

Ugukomera kw'ugufatanya

Kugabanya ivyuka biva muri formaldehyde

MUF ikoreshwa cane muri:

Imbaho ​​zifise amaso y'ibara ry'agahama (3聚氰胺贴面板)

Ibiti vyinshi -

Igiti co gushaza c'agaciro kanini

Ni uburyo bwa mbere bwo gufatanya E1 n’ibindi bipande vya E0.

2.3 Igikoresho ca Fenoli (PF)

Ivyuma bifatanya PF bitanga ubushobozi bwiza cane:

Uguhangana n'amazi cane

Ubushuhe bushikama

Uguhangana n'ikirere

PF-ibiti vy’amabuye bifatanye birashobora kwihanganira ibigeragezo vy’amazi ashushe (Ibiti vy’amabuye vy’ubwoko bwa I).
Ivyo gusaba birimwo:

Ivyuma vy'ubwubatsi

Ibiti vy'inyuma

Imiterere ya OSB

Ibipande vy'ikiyaga-

Ibara ryayo ryirabura rigabanya ikoreshwa mu bikorwa vyo gushaza.

2.4 Ivyuma bifatanya MDI / pMDI

PMDI ifatwa nk’imwe mu bikoresho vy’ugufatanya biteye imbere cane kw’isoko:

Zero yongeyeko formaldehyde

Uburyo bwiza cane bwo guhangana n'amazi

Inkomezi nyinshi zo gufatanya

Uguhangana n'ukuvyimba

PMDI ikoreshwa muri:

OSB y'imbere

Nta-yongeweko-ibipande vy'ibipande vya formaldehyde

Igiti gikozwe mu buryo bwiza cane-

Igiciro ni kinini, ariko ubushobozi ntaco bugereranywa.

3. Ivyiyumviro vy'ibidukikije n'ibifatanya

Ivyiyumviro vy’umutekano w’ibidukikije bigenwa n’ubuhinga bwa shimi bw’ivyuma.
Aha hepfo hariho isano ryoroshe:

Iciyumviro: ubushobozi bw’ibisohoka burashikirwa n’ubushuhe bw’ibara ry’agahama, igihe co gukira, igipimo c’amabara, n’ugutera imbere.

4. Uko womenya uburyo bwo kwifatanya mu bipande vy’ibiti

4.1 Raporo z'ibigeragezo

Saba:

Ivyavuye mu kigeragezo c'imyotsi ya formaldehyde

Inkomezi zo gufatanya (RU 314, JAS, GB/T ingingo mfatirwako)

Raporo z'igerageza ry'ibiti vya PF

4.2 Gusuzuma umubiri

Ubufatanye bw'urubibi

Ibimenyetso vy'ubusa bwo mu mutima

Ugusenyera kw'imbere

4.3 Guseruka kw'abahinguzi

Abahinguzi bizigirwa bamenyesha uburyo bwo kwifatanya kandi bagatanga ivyemezo.

5. Ivyerekeye Gukoresha & Uburyo bwo Kwifatanya

6. Kazoza k’Ibifatanya mu Nganda y’Ibiti

Ivyiyumviro vy'inganda vyerekana ko hariho uguhinduka ku:

6.1 Formaldehyde-Ikoranabuhanga ry'ubuntu

PMDI n’ivyuma bishingiye ku binyabuzima-biriko biragwira cane.

6.2 Ivyagezwe vy'Ibikorwa vy'Igihugu

Igihe kirekire-iramba, hejuru-inkomezi z'ugufatanya ku bikorwa vy'imiterere n'ivy'umwihariko.

6.3 Ibisubizo vy'icatsi kibisi, bishobora gusubirwamwo

Ivyuma bifatanya bishingiye kuri soya-, ivyuma bifatanya lignin-vyahinduwe, n'ubuhinga bushingiye ku mazi-.

Iciyumviro

Ivyuma bifatanya ni vyo bikoresho nyamukuru biri inyuma y’igipande cose c’ibiti. Bagena:

✔ Ikigero c'ibidukikije
✔ Inkomezi z'ubuhinga
✔ Uguhangana n'ugukura
✔ Umutekano wo gukoresha mu nzu
✔ Ukwiriye kwubakwa canke ibikoresho vyo mu nzu .

Ku baguzi, abazana ibintu hanze, n’abahinguzi, gutahura uburyo bwo kwifatanya bituma umuntu afata ingingo nziza zo kuronka aho ashaka kandi akagira agaciro kanini k’ibintu.
