Masiku awiri apitawo, kasitomala adanena kuti plywood yambiri yomwe adapeza idasokonekera pakati ndipo mtunduwo unali woyipa kwambiri.Amandifunsa za momwe ndingadziwire plywood.Ndinamuyankha kuti mankhwalawo ndi ofunika ndalama iliyonse, mtengo wake ndi wotsika mtengo kwambiri, ndipo khalidweli silingakhale bwino kwambiri.

Ndidapatsa kasitomalayo mndandanda wamafunso omwe amafunsidwa pafupipafupi za plywood ndikusanthula kapangidwe ka plywood.

Zotsatirazi ndi gawo la zomwe zili

FAQ:

1. Ming'alu: Zifukwa: ming'alu yamagulu, bolodi yomatira imakhala ndi ming'alu.Njira zodzitetezera: Posankha (posankha matabwa), samalani kuti musankhe, sungani matabwa apulasitiki osawononga, ndi kuwakonza bwino.

2. Kuphatikizika: Chifukwa: bolodi la pulasitiki, bolodi lowuma, kudzazidwa ndi kwakukulu kwambiri (nthawiyi ndi yayikulu kwambiri (yochepa kwambiri) Njira zodzitetezera: lembani dzenje molingana ndi kukula kwake, ndipo simungathe kupitirira dzenje loyambirira.

3. Kutaya koyera: Chifukwa: Sichifanana mokwanira pamene mafuta ofiira amadutsa kamodzi kapena kawiri.Njira zodzitetezera: Poyang'anira, onjezerani mafuta ofiira pamanja.

4. Bolodi lophulika: Chifukwa: bolodi lonyowa (bolodi lapulasitiki) siliuma mokwanira.Chenjezo: Yang'anani matabwa apakati potumiza.

5. Pamwamba pa bolodi ndizovuta: Chifukwa: lembani dzenje, mchira wa mpeni wa matabwa ndi wochepa thupi.Njira zodzitetezera: yesani kusankha bolodi lopanda matabwa.

Pakatikati pa board (bolodi limodzi) nthawi zambiri amagawidwa kukhala: 4A giredi (pachiyambi chonse ndi bolodi lonse), 3A pachimake cha board chokhala ndi mabowo ochepa ndi bolodi yovunda.The veneer ayenera kulabadira makulidwe yunifolomu, kotero kuti si kophweka warps (otsetsereka), ndi youma ndi yonyowa katundu ndi zabwino, kotero si kophweka peel (kuwira).Mtanda nthawi zambiri umakhala wa 50-60 filaments, zosakwana 30 ndizosavuta kuti gululo lisungunuke.The wandiweyani mtanda, ndi yosalala pamwamba pa bolodi, pang'ono kusintha (carbonization), ndi plywood si zophweka anang'ambika pamene demoulding, ndi pamwamba zotsatira zabwino, ndipo chiwerengero cha turnovers nawonso kutsimikiziridwa.

Kupanikizika kwa atolankhani nthawi zambiri kumakhala pafupifupi 180-220, kukanikiza kotentha kumakhala kopitilira mphindi 13, ndipo kutentha ndi madigiri 120-128.Ngati kupanikizika kwa makina osindikizira sikuli kokwanira, kumamatira kwa plywood sikuli bwino, ndi kusweka, osati kumamatira bwino.Kuchuluka kwa guluu wosanjikiza umodzi kuyenera kukhala pafupi ndi 0,5kg, ndipo kuchuluka kwa guluu kumakhala kochepa, ndipo plywood ndi yosavuta kuphulika ndi delaminate.

 Pali mabowo ambiri pakatikati pa plywood yocheka.Kumbali imodzi, zopangira ndi zotsika, ndipo bolodi loyipa limagwiritsidwa ntchito ngati bolodi labwino.Kumbali ina, ogwira ntchito opangira zinthu alibe luso lolemba zilembo, ndipo kusiyana pakati pa veneer ndi yayikulu kwambiri.

 Ubwino wa poplar core board ndikuti mtengo wake ndi wotsika mtengo.Zoipa: Kuchulukana kwa veneer ndi kochepa, kuuma kwake kumakhala pafupifupi, ndipo khalidwe la bolodi ndilopakati.

Ubwino wa eucalyptus core board ndi wabwinoko (wosinthika kwambiri).Kuipa: okwera mtengo pang’ono

 Kum'mwera kuli bulugamu wochuluka, ndipo Guangxi amayang'ana kwambiri kupanga phala la bulugamu.

Kumpoto kuli mipopi yambiri, ndipo pali plywood yambiri ya poplar ku Shandong ndi Jiangsu.

  Zogwirizana ndi zinthu zathu:

Ufa wa 25% -35%

Chigawo chimodzi (mbali ziwiri) chimakhala ndi guluu pafupifupi 0.5kg

Chidutswa chimodzi cha mtanda ndi silika 50, ndipo pamwamba pa 13mm ndi silika 60.(mtengo wa paini)

Zomwe zili mu melamine 12% -13%

Cold Press 1000 masekondi, 16.7 mphindi

1.3 Kukanikiza kotentha kwa masekondi pafupifupi 800 1.4 Kukanikiza kotentha kwa masekondi opitilira 800 mphindi 13.3

Njira yopangira: kukanikiza kotentha

Makina osindikizira ndi atatu (silinda) pamwamba pa matani 600, kuthamanga 200-220, nthunzi yotentha.

Kutentha kwa kutentha kwa madigiri 120-128 kugawidwa m'magawo atatu

Zopangira 2mm-2.2mm, bolodi lonse lapakati
