Softwood plywood: zofunika kupanga ndi olemba. plywood WBP

Plywood - Kupanga chuma cha zigawo inakula nkhuni (maonekedwe).

mbali

The katundu yaikulu ya plywood zimadalira mtengo womwe zonse. Kuyambira mutu izo zamveka kuti plywood softwood amapangidwa softwood (spruce, paini). The zigawo za maonekedwe ndi mtima kuti ulusi anali perpendicular kwa wina ndi mzake.

Main makhalidwe zakuthupi:

• The mtengo wotsika.
• Kuwala kulemera zakuthupi.
• Kukamaomba kusintha kutentha.
• Chinyezi kugonjetsedwa.
• Mkulu mphamvu chifukwa kukhalapo kwa zigawo.
• Yosavuta kugwiritsa ntchito (akhoza anachekedwa, mokhomerera, ndi zina zotero. D.).
• Iwo zimatenga phokoso.
• Ali ngati wosanjikiza kutchinjiriza.
• nkhuni ndi impregnated ndi utomoni zachilengedwe, zomwe zimapangitsa chuma kugonjetsedwa ndi cinoni ndi bowa.
• kugonjetsedwa kwambiri TV aukali.
• Azisangalala wokongola chifukwa owonetseredwa kapangidwe nkhuni.

njira plywood opanga

Pali njira zitatu:

1. Activities. Nkhuni maonekedwe ndi kusema n'kupanga 5 mm wandiweyani. Mu njira imeneyi uneconomically ankadya chakudya.
2. Slicing - kwambiri ndalama njira kupeza 3.5 mamilimita wandiweyani maonekedwe.
3. Ukuchoka maonekedwe zipika - njira imene anakonza maonekedwe makulidwe a mamilimita 1.2 kuti 1,9.

Kodi bwino plywood: birch kapena softwood?

Zosiyanasiyana angagwiritsidwe ntchito yopanga mitundu ya mtengo paini ndi hardwoods. The katundu wa zinthu zimadalira, ndithudi, kwa zipangizo zopangira. Mtundu uliwonse ubwino komanso kuipa.

plywood Softwood ndi angapo ang'onoang'ono a zigawo. Chuma cha larch, cholimba kwambiri, ndinapirira ndi kumva kuwawa kugonjetsedwa. Kwa zinthu cholimba bwino kusankha birch plywood.

Veneers wa birch ali ndi opepuka mthunzi ndi kapangidwe bwino chionetsedwe. Conifers, pa mwake, mdima ndi kukhala zabwino kutchulidwa chitsanzo.

nkhuni Coniferous impregnated ndi resins achilengedwe. Chifukwa ichi, zipangizo anapangidwa kuchokera amachepa poyera kuti cinoni ndi bowa. Coniferous plywood - ichi ndi ndi wotchipa zomangila.

chodetsa

Khalidwe la zinthu zimadalira zomatira umene ntchito kulumikiza zigawo maonekedwe. Malinga plywood izi softwood ali kulemba zingapo:

• ABF - otsika luso la mtunduwu. Iwo chopangidwa ntchito albuminkazeinovogo zomatira. Zimene zimapangitsa kuti zinthu wochezeka. Koma chinyezi zinthu sangaime. Izo ntchito kokha kumene kulibe chitetezo madzi.

• FSF - mtundu wotchuka kwambiri, pogwiritsa ntchito phenol formaldehyde ulimbo. Ndi cholimba kwambiri ndipo madzi zosagwira.

• PSF-TV isiyana ndi FSF mtundu retardants impregnation. Chifukwa ili, mtundu wa plywood softwood ali combustibility osauka.

• FC pogwiritsa ntchito urea zomatira, zomwe zimachititsa zinthu hygroscopic kwambiri. Ntchito kupanga mipando, ma CD, nyumba mkati.

• SE Water zosagwira si poyera kuti chilengedwe mtopola. Thiabendazole angagwiritsidwe ntchito ngakhale pansi pa madzi. Izi zimatheka ndi kulumikiza zigawo za zomatira ndi impregnated ndi bakelite varnish chomwecho.

• BS - ndege plywood, amene nalo dzina lake chifukwa cha ntchito zake ndege ndi shipbuilding. Bakelite maonekedwe glued zomatira mowa sungunuka. Softwood plywood mukulemba izi madzi, cholimba, kugawa kugonjetsedwa TV aukali.

• BV ali ndi katundu mofanana BS lapansi. Kusiyana komwe kulipo ndi chuma kulemba mantha madzi (pogwiritsa ntchito sungunuka madzi zomatira).

Mitundu yonse ya plywood osiyana pamwamba pa mapeto. Malinga izi, ndi za mitundu itatu: unpolished (NSH), ndi munthu amaganiza akupera (SH1) ndi nthaka mbali ziwiri (R2).

PSF

Softwood plywood WBP ndi otchuka kwambiri pomanga ntchito zaboma ndi mafakitale. kukana yake madzi ndi chifukwa impregnation zigawo bwino sungunuka formaldehyde resins. Pambuyo impregnation, zigawo maonekedwe ndi poizoni pansi atolankhani pa kutentha.

GOST zovomerezeka Kugawilidwa kwanthaka ena kuchuluka kwa formaldehyde ndi phenol mankhwala. Izi complicates ntchito plywood mwachindunji m'nyumba.

PSF plywood mapepala ndi miyeso muyezo :. 1,22h2,44 m, 1,25h2,50 m, 1,525h3,050 m, mamita 1,525h1,525 Imodzi makulidwe zimasiyanasiyana mkati 4-30 mm.

Softwood chizindikiro plywood WBP Anthu ambiri amagwiritsa ntchito. Malangizo chachikulu cha ntchito zake:

• nyumba zosakhalitsa pa ntchito yomanga.
• maofesi sheathing.
• The alipo pansi pa denga.
• Pomanga magalimoto, magalimoto ndi ziwiya khungu lawo.
• Kuti akonze munda ndi munda mipando.
• Kumangira formwork (ndipo zinthu zikhoza kugwiritsidwa ntchito mobwerezabwereza).
• Monga chuma yaiwisi kwa kupanga zinthu zina.

Plywood - zotsika mtengo komanso apamwamba zinthu nyumba, umene uli wotchuka mu msika kwa nthawi yaitali.
