Chii chinonzi fiberboard?
Density board imhando yeartificial board, inonyanya kugadzirwa nePine huni kana imwe plant fiber seyakabikwa, nekuwedzera urea formaldehyde resin kana imwe adhesive inoshanda mushure mekupisa kwakanyanya uye kudzvinyirira kwakanyanya kurapwa 1. Inoratidzwa neuniform density, yakatsetseka pamusoro, haisi nyore kudhizainira, kutsemuka uye kudzima, asi zvakare nyore kupenda nekushongedza. Pamusoro pezvo, kugona kwemuchina we density board yakanaka, iri nyore kucheka, kudhiraivha, kuveza uye kupuruzira, yakakodzera kugadzirwa kwemuchina uye kugadzirisa manyore.
Maererano nehuwandu hwemapuranga emagetsi, anogona kugoverwa kuva pasi-density board, medium-density boards uye high-density board. Density ye low-density board iri pazasi 400kg/m³, iyo inonyanya kushandiswa kune yemukati chimiro chefenicha, senge mabhodhi emibhedha, wadhiropu, nezvimwewo, asi density yayo ishoma, huremu huremu, uye kushomeka kwesimba. Density yepakati density board iri pakati pe400-800kg/m³, inova inowanzoshandiswa density board, yakakodzera fenicha, kushongedzwa, kurongedza nemimwe minda. Kuwanda kwepamusoro-density board kunodarika 800kg/m³, uye kusimba kwayo nekuoma kwayo kwakakwira zvakanyanya kupfuura iyo yepakati-density board, iyo inoshandiswa zvakanyanya mumhando yepamusoro fenicha, kuvaka nemimwe minda.
Density boards inoshandiswa munzvimbo dzakasiyana-siyana, kusanganisira mapuranga efenicha, mapuranga ekushongedza uye mapuranga ekuvaka. Furniture board imhando yebhodhi rakagadzirwa ne density board seyakabikwa, inonyanya kushandiswa kugadzira fenicha. Decorative board imhando ye density board yakaputirwa nehuni zviyo, zviyo zvematombo uye mamwe mapatani, anonyanya kushandiswa kushongedza mukati. Kuvaka bhodhi imhando yebhodhi rakagadzirwa ne density board seyakabikwa, inonyanya kushandiswa mundima yekuvaka 2.
Nekudaro, iyo density board inewo zvimwe zvinogumira, senge huremu hwayo hukuru, yakaoma kufambisa uye kuisa, uye iyo yepamusoro inokonzeresa kunyorova deformation, inoda hunyoro-huchapupu kurapwa3.
