Kale pa siteji ya akamaumba mbale kwapatsidwa mwa mlingo wa madzi kukana. Izi zachitika ndi kusintha kapangidwe wa resins kupanga ntchito ogwirizana zigawo. Chotero, podziwa mankhwala ntchito monga zomatira ndi n'zotheka kudziwa mlingo wa chinyezi zakuthupi:

• Mbale pogwiritsa ntchito urea zinthu ndi malire a kukana chinyezi m'dera la 5-10%. zomangira amatha kupirira yochepa chinyezi.
• 10-15% kukana kwa chinyezi umathandiza ntchito Nyimbo phenol-formaldehyde. Mbale wa mtundu uwu angagwiritsidwe ntchito ofunsira kunja.
• Plywood madzi zosagwira laminated kosamugonjera kudzitsitsa chifukwa cha chinyezi. Kumatetezera filimu waikamo padziko mbale.

Ubwino wa chuma ndi kuipa kwake

The njira ya ulimi zimapangitsa plywood cholimba ndi kugonjetsedwa ndi mapindikidwe. Izi zimatheka ndi kukhala zigawo zingapo ndipo zomatira wapadera. Choncho, tingachite bwino kunena za Ubwino mbale amenewa:

• Kukana kuti chinyontho. Madzi plywood kosamugonjera kudzitsitsa chifukwa cha chinyezi. Zilibe unstuck pa zigawo ndipo si olumala.
• Yosavuta kugwiritsa ntchito. Mkulu mphamvu zakuthupi sikusokoneza processing. Plywood zikhoza kukonzedwa ndi thandizo zosiyanasiyana zipangizo. zosavuta ake kukhazikitsa.
• Ngakhale ndi zipangizo zina nyumbayi. Nthawi zambiri, madzi zosagwira plywood ntchito monga chuma ndi zina. Mosavuta zikugwirizana ku zachilengedwe ndi polima zomangira.
• Kuvala kukana. Plywood chingathe kupirira makina maganizo popanda kulephera umphumphu.
• Kukana monyanyira kutentha.
• Chithunzi lonse la ntchito.
• Aesthetics. Plywood zikuoneka ali choyambirira nkhuni chitsanzo ndi mtundu.
• mtengo angagulidwe. plywood mbale ndi mtengo kuposa matabwa olimba. Ndipo inu nthawi zonse kupatula ndalama ndi kusankha mfundo ya m'munsi kalasi.

The drawback yekha chuma ndi pamaso pa zoipa zinthu m'gulu zomatira ndi. Tikuyankhula zokhudza formaldehyde. Kotero osavomerezeka ntchito plywood m'madera zogona ndi pamene pali ana kapena anthu ndi chifuwa.

dera ntchito

Madzi plywood ntchito zosiyanasiyana ntchito. Nthawi zambiri ndi ntchito pomanga. Izo ntchito mu njira zotsatirazi:

• Skinning makoma, pansi panyumba madenga.
• Mkati chokongoletsera nyumba.
• Pakuti zotsimikizira zinthu zokongoletsera.
• Monga formwork reusable.
• Pakuti zikwangwani.
• Pakuti makampani ma CD.

Chifukwa mphamvu, durability ndi kuwala kulemera, madzi plywood ntchito yomanga ngalawa, zoyendera sitima munda mipando. Angalekanitse chikuoneka kwa birch shelled ntchito ngakhale mu ndege.

mitundu ya mbale

Popeza kuchuluka kwa kukana chinyezi, plywood unapangidwa mitundu ingapo:

• FC. chuma ichi, chimene chopangidwa ntchito karbomidoformaldegidnyh nyimbo. Iwo ali mkulu chinyezi kukana. Koma ali bwino ntchito zachilengedwe. Kugwiritsidwa ntchito mkati, mipando ndi zokongoletsa.
• PSF chawonjezeka chitetezo ku chinyezi. The ntchito monga zomatira phenolformaldehyde utomoni. Zakuthupi yomweyo kupanga pansi akhakula, denga battens, kupanga ma CD, zikwangwani.
• PBS ali ndi chitetezo chachikulu kwa chinyezi ndi kutupa. Iwo bakelized madzi zosagwira plywood. Ntchito mu shipbuilding ndi ndege kupanga.

Maonekedwe, madzi plywood lagawidwa sukulu asanu (1 kuti 5). Ngati mbale anapangidwa kwa yolimba, manambalawo patsogolo pa kalata E anawonjezera kuti ankachita. Pankhani ya coniferous feedstock ntchito kalata H.

Ndi pamwamba chithandizo zinthu khalidwe kusiyanitsa unsanded (NS) ndi umodzi amaganiza kupukuta (III-1) ndi iwiri amaganiza kupukuta (III-2).

Palinso gulu malingana formladegidov chiwerengero m'nkhaniyo. Pamene zili mamiligalamu teni pa magalamu mazana a kulemera kwa zinthu, kulankhula za nkhani ya kalasi E-1. Ngati utomoni lili khumi ndi makumi atatu mamiligalamu, ndiye kusonyeza kalasi E-2.

Makulidwe mbale

Miyeso pafupifupi nkhani 1,22h2,44, 1,25h2,50, 1,52h3,05, 1,52h1,52 m. Izi si onse, koma miyeso yaikulu imene plywood madzi. The makulidwe a mbale angakhale kuchokera mamilimita 9 40. Izo zimatengera chiwerengero cha zigawo nkhuni. Pangakhale zitatu makumi awiri ndi chimodzi.

• Plywood anapanga mtundu FC kutalika 1.525 m. M'lifupi Imatha 1,22, 1,27 kapena 1,525 m.
• PSF ali ndi m'lifupi mwake 1,22 ndi 1,25 m. M'litali ndi 2,44 kwa 2.5 m.

ndemanga wosuta

Malinga ogula madzi plywood - zakuthupi quality, amene sakuopa chinyezi ndi zochitika mumlengalenga. Amaonanso mphamvu mkulu wa nkhaniyo.

Komanso, pali chomasuka unsembe ndi kulipira. Mbale akhoza nyundo ndi misomali zomangira kumangitsa, kupanga obowoka, ndi zina zotero. Ndipo zonse izi sayambitsa mavuto alionse.

Wa minuses anthu okonda afotokoze vuto mayendedwe a plywood. Ichi ndi chifukwa miyeso lalikulu. Makulidwe madzi plywood nthawi zonse kuposa mita imodzi. Chifukwa ichi, mbale aikidwa osati mitundu yonse ya galimoto. Choncho, kwa zoyendera zakuthupi n'kofunika kuyang'ana mayendedwe abwino.
