Bakelite plywood: makhalidwe, ntchito

Plywood bakelite ndi cholimba, ndinapirira, madzi zosagwira, kuvala zosagwira chuma, ngakhale otsika khalidwe alloyed zitsulo. kuti onse - chifukwa cha luso lapadera limene ali impregnated ndi maonekedwe bakelite birch ndi zomatira pa kutentha ndi opanikizika. Chotero plywood, lotchedwa "nyanja" sakuopa wa madzi, magetsi. Iwo akhoza opareshoni pa kutentha kwa opanda 50 kuphatikiza 50 Celsius. Zakuthupi si kuvunda, si anaphimba ndi bowa, angagwiritsidwe ntchito m'mayiko otentha ndi chinyezi pa gombe. moyo utumiki - kwa zaka 15.

njira kupanga

gawo loyamba. Kwa kupanga plywood kalasi Ine zigawo zake kwathunthu kumizidwa utomoni, pakuti kupanga zinthu maonekedwe kalasi II chabe topaka.

Gawo lachiwiri. mapepala ndi mbamuikha pansi ndi mavuto 4 MPa.

Mbali yachitatu. Plywood anali utakhazikika opanikizika.

Kuthamanga amalola impregnated kwathunthu zigawo ndi kupeza plywood woonda. Komanso, kukanikiza amapanga zinthu kugonjetsedwa ndi malowedwe chinyezi.

makhalidwe luso

Kumasulidwa chuma mu mawonekedwe chinsalu cha 1250 mamilimita m'lifupi ndi 1500 mamilimita kutalika Pankhaniyi akhale 2800 mm, 5650 mm, 5700 mm. Analola chakuti kutalika pafupifupi 40 mm m'lifupi - 20 mm. The makulidwe a ranges ndi maonekedwe kuchokera 5 mm 20 mm (zolakwa za 2 mm). Zofunika kachulukidwe - pazipita 1.2 MPa. Mosiyana ochiritsira, bakelite plywood anayimiridwa mwa mitundu mdima, amangoona red-bulauni.

Plywood ali yosalala pamwamba, amene sanaloledwe ndi dents, zimakhalapo, odzigudubuza, ziyangoyango zipsera. Ukwati imatengedwa bakelite plywood ndi nepromazannymi ndi malo impregnated mutsanulira nedopressovkoy, mitolo.

Minda ya ntchito

Chifukwa cha makhalidwe ambiri opindulitsa, bakelite plywood ndi bwino ntchito m'mafakitale zosiyanasiyana. Monga galimoto, shipbuilding, ndege zomangamanga, luso lopanga, hayidiroliki makampani zomangamanga, yausangalatsi, maseŵeralo zaluso. Ngati ife kulankhula za ntchito makamaka, chuma kwambiri denga, simenti, adzikometsa, makoma, formwork, kudenga, pomangira, simenti m'mabasi, nthandala chionetsero ndi zinthu zina.

kalasi plywood

Mu msika zopangidwa angapo bakelite plywood: PBS, PBS-1, 1a-FBS. Mitundu iwiri yoyambirira m'mene kumatheka kukana kuti madzi ndi moto, tinapangidwa ntchito zomangamanga, shipbuilding. Mtundu lachitatu mwapadera kwa makampani magalimoto. atsopano mtundu chinyezi kukana penapake m'munsi chifukwa utomoni impregnated ndi zigawo yekha kunja, koma iye ndi yotsika mtengo.

The zigawo chapamwamba maonekedwe PBS ndi PBS-1 zopangidwa ndi maonekedwe kalasi ine, mkati - maonekedwe II maonekedwe. PBS-1a anapanga kwathunthu ku zopangira II zosiyanasiyana.

Mwa njira zinthu Machining ndi unpolished, wopukutidwa (ndi mbali imodzi kapena ziwiri).

Bakelite plywood ubwino zitsulo otsika-alloyed

N'chifukwa chiyani akatswiri amakonda mokomera plywood? Pamodzi ndi katundu monga madzi kukana, overstrength, moto kukana ndi elasticity, chuma ndi kuwala ndipo sanali zikuwononga, zomwe zimathandiza kuti ntchito m'mikhalidwe chinyezi mkulu, ndipo ngakhale pansi pa madzi.

Chopangidwa ndi anagulitsa bakelite plywood mu Moscow. A osiyanasiyana mankhwala, zotchipa, kutumiza koloko, yobereka mwachindunji, pazipita mayiko kwa makasitomala - mfundo yaikulu ya opanga.
