matabwa olimba tinthu bolodi ndi angapo wosanjikiza matabwa olimba bolodi ndi zinthu zambiri ntchito.Ndi iti mwa awiriwa yomwe ili yabwino?
Chabwino n'chiti, bolodi lamatabwa olimba kapena bolodi lamitundu yambiri?
Olimba nkhuni tinthu bolodi kwenikweni bolodi opangidwa ndi ndondomeko ya tinthu bolodi, ndipo akhoza kuonedwa ngati mtundu wa homogeneous tinthu bolodi.Pambuyo pa homogeneous particle board yaumitsidwa ndi chowumitsira chapamwamba cha single-channel, coefficient yowonjezera ndi yaying'ono ndipo kukana kwa chinyezi ndikwabwino kwambiri.Poyerekeza ndi ufa wa MDF, mphamvu yogwira misomali, kukana kupindika ndi kukhazikika kuyenera kukhala kolimba.
Bolodi lolimba lamitundu yambiri limapangidwa ndi criss-wowoloka plywood yamitundu yambiri ngati maziko, ndipo pamwamba pake amapangidwa ndi matabwa olimba kapena matabwa aukadaulo monga nsalu, ndipo amapangidwa ndi njira zingapo monga kukanikiza kuzizira, kutentha. kukanikiza, mchenga, ndi kuteteza thanzi.Chifukwa Mipikisano wosanjikiza olimba matabwa bolodi ali ndi makhalidwe osavuta mapindikidwe ndi ntchito yabwino ya kusintha kutentha m'nyumba ndi chinyezi, ndi pamwamba wosanjikiza olimba nkhuni veneer zakuthupi ndi kapangidwe ndi kumverera kwa chilengedwe matabwa enieni, kotero selectivity ndi wamphamvu.Choncho, amakondedwa ndi ogula.Gulu lamatabwa lolimba lamitundu yambiri lili ndi kukhazikika kwadongosolo, sikophweka kupunduka, ndipo ndi lolimba mumtundu.
Ubwino ndi kuipa kwa plywood yolimba yamatabwa?
1 Thanzi labwino komanso lokonda zachilengedwe lokhala ndi matabwa olimba ambiri limapewa kugwiritsa ntchito guluu wamadzimadzi popanga guluu, ndipo formaldehyde ilipo mu guluu wamadzimadzi, motero guluu lamitundu yambiri lolimba ndi lokonda zachilengedwe komanso lathanzi kuposa plywood.Bolodi lamatabwa lolimba lamitundu yambiri limapangidwa ndi zigawo zingapo za plywood zokonzedwa munjira ya criss-cross monga maziko, ndipo amapangidwa ndi njira zingapo monga kukanikiza kozizira, kukanikiza kotentha, kusenda mchenga, komanso kuteteza thanzi.Njira yapadera yopangira ndi kusankha kwa zida zopangira matabwa olimba amitundu yambiri zimatsimikizira mtundu wake wapadera.
2 M'malo mwake, matabwa olimba amitundu yambiri amapangidwa ndi magawo awiri: matabwa olimba a pamwamba ndi matabwa olimba.Mapanelo a matabwa olimba amitundu yambiri ndi otsika mtengo kuposa mapanelo okwera mtengo olimba.Pansi pa matabwa olimba akadali opunduka komanso ong’aluka.Pali zochitika ziwiri zazikulu.Mapanelo amatabwa olimba amitundu ingapo amamatiridwa molunjika komanso mopingasa.Pambuyo pa kutentha kwakukulu ndi kuthamanga kwakukulu, kupanikizika kwamkati kumathetsedwa.Imathetsa zovuta ziwiri zazikulu za deformation ndi kusweka kwa mapanelo a matabwa olimba.
3 Pamwamba pa matabwa olimba amitundu yambiri amapangidwa ndi matabwa osankhidwa atatha kuyanika, kupukuta, ndi kusunga thanzi., kusiyana kwa mtundu sikungakhale kovuta kwambiri, chifukwa ichi ndi katundu wachilengedwe wa nkhuni.M'malo ena, chinyezi cha matabwa olimba amitundu yambiri chimakhala 5% -14%.
4 Mipikisano wosanjikiza matabwa olimba bolodi: ntchito bulugamu Mipikisano wosanjikiza bolodi, mankhwala akukumana ndi chilengedwe kuyezetsa muyezo E1 mlingo, ali ndi makhalidwe a antibacterial, mildewproof ndi madzi, asidi ndi zamchere kukana, odana ndi kuipitsa ndi kuyeretsa mosavuta, palibe kununkhira kwa penti, palibe kununkhira kwa fir, etc., bolodi loyambirira ndi lathyathyathya Silopunduka, ndi mankhwala okongoletsera kunyumba.Ma matabwa olimba amitundu yambiri nthawi zambiri amagwiritsa ntchito matabwa omwe amakula mwachangu ngati maziko, ndipo pamwamba pake amavekedwa ndi veneer wapamwamba kwambiri.
