Kusiyana kwa nsungwi ndi nkhuni

Kusiyana pakatinsungwi ndi matabwa:

Kukhudzidwa ndi zida zosiyanasiyana za nsungwi ndi matabwa palokha,matabwa a bamboondizosiyana ndi bolodi lamatabwa potengera zakuthupi komanso zamakina. Mapulani ambiri amatabwa sali abwino monga ubwino wa makhalidwe abwino, monga mphamvu yapamwamba, kusungunuka bwino komanso kukana mphamvu. Bamboo board ndi nsungwi kapena zinyalala zansungwi monga zopangira zazikulu, kudzera pakuchiritsa thupi ndi mankhwala komanso kudula makina, kusinthidwa kukhala mawonekedwe osiyanasiyana amitundu yamagawo omangika, atatha kusanja kuti apange mitundu yosiyanasiyana ya tebulo labala la slab lopangidwa ndi bolodi lopanga. Amachotsa zofooka za anisotropy, zinthu zosagwirizana komanso kung'ambika kosavuta kwa nsungwi. Ikhoza kugonjetsedwa ndi tizilombo, osati zosavuta ku mildew komanso zovuta kusokoneza.

Chifukwa nsungwi palokha ndi zinthu zokhala ndi mainchesi ang'onoang'ono, khoma lopanda pake komanso lopyapyala, zimaletsa kugwiritsa ntchito nsungwi kwambiri, ndipo kafukufuku ndi chitukuko cha nsungwi zopangidwa ndi matabwa zimapangitsa kuti nsungwi ikhale ndege kapena zinthu zapamtunda zokhala ndi mawonekedwe akulu komanso mphamvu yayikulu, zomwe zimapangitsa kuti nsungwi zaku China zilowe m'nthawi yogwiritsira ntchito mafakitale.

Wood mbale ndi matabwa kapena matabwa zinyalala monga waukulu zopangira, mwa mankhwala thupi ndi mankhwala ndi kudula makina, kukonzedwa mu zosiyanasiyana akalumikidzidwa structural mayunitsi, ndiyeno kudzera mu billet kapena m'njira mu mitundu yosiyana structural tebulo labala labala zopangidwa ndi mbale chuma. Wood mbale kubweza kuchepetsa kupanikizika kwa kusowa kwa matabwa chuma, ndi njira yabwino ntchito mofulumira kukula nkhuni, matabwa ang'onoang'ono, kusintha mlingo magwiritsidwe ntchito matabwa, ndi kugonjetsa zina zolakwika matabwa palokha, kukwaniritsa ntchito yaikulu ya nkhuni yaing'ono, mtengo wotsika.

nsungwi ndi matabwa ali ndi makhalidwe awo, bnsungwi ndi matabwa amagwiritsidwa ntchito kwambiri ngati zopangirazinthu zapakhomondizinthu zakukhitchini.
