Chipboard - ib tug tseem ceeb ntawm kev tsim kho

Chipboard yog dav kis nyob rau hauv lub niaj hnub ntiaj teb no, tshwj xeeb yog nyob rau hauv kev tsim kho. Nws yog ib qho tseem ceeb feem ntawm zus tau tej cov rooj thiab Qhov rai, ua hauj lwm pab raws li lub hauv paus rau cov phab ntsa, qab nthab thiab hauv pem-teb.

Chipboard yog compacted webs ntawm ntoo daim tawv nyias thiab cov kua nplaum. Tiabsis cov opilochnoj loj tshwm sim li ib tug tshwm sim ntawm cov kub pressing txheej txheem. Qhov no saib kuas txhim khu kev qha kev twb kev txuas Cheebtsam ua ke. Cov nplaum siv rau lub hom phiaj no, muaj ib tug tshwj xeeb pes tsawg leeg raws li formaldehyde thiab lwm yam additives.

Txhua chipboard hais txog tej pab pawg nyob rau hauv lub dav dav cais. Txawv los ntawm ib tug qauv ntawm cov raug particleboard thiab qhov xwm ntawm compression, lub nplaum muaj pes tsawg leeg cov ntaub ntawv uas, hom ntoo uas los ntawm tus chips tau txais, los ntawm daim ntawv liner thiab ib co lwm yam tsis.

Zoo chips siv ncaj qha muaj feem xyuam rau qhov zoo thiab cov yam ntxwv, uas yuav tsum tau muab tej txiaj ntsim nrog chipboard. Piv txwv li, los ntawm cov ntoo, muaj paj nplaim paj zoo, tau chipboard muaj zog dua thiab kuj mus hloov tau. Tab sis qhov zoo ntawm cov square, on qhov tsis tooj, yuav ua rau nws heev puas yooj yim thiab tsis zoo resistant rau dabtsi yog khoov kev nyuaj siab. Los ntawm kev siv xws raw cov ntaub ntawv, cov chaw tsim tshuaj paus yog yuam kom nce tus nqi ntawm cov cob rau muab cov kev tsim nyog zoo yam ntxwv. Txawm li cas los, qhov no ho tsub kom tus tsis zoo feem on qhov ib puag ncig vim yog lub tshem tawm ntawm tshuaj lom formaldehyde.

Niaj hnub nimno Chaw tsim tshuaj paus yog peev xwm los tsim chipboard ob hom: U-A thiab II-B. Chipboard thawj hom yog yus muaj los ntawm tseem ceeb ntsuas ntawm lub dag lub zog, xws li tensile thiab dabtsi yog khoov los, thiab me nuj nqis nyob rau hauv cov nram no ntau: deformation, roughness thiab nyiam swell. Nyob rau tib lub sij hawm stamp P-B daim hlau muaj me ntsis ua tsis tau zoo kawm piv nrog particleboard hom P-A.

Tam sim no ua CPD kuv thiab qib II, raws li zoo li sub-standard. Chipboard ranked raws li ib ntawm cov pab pawg raws li zoo yam ntxwv muaj los ntawm qhov chaw txheej. Yuav kom tau raws li tag nrho cov uas yuav tsum tau ntawm kuv qib, particle board yuav tsum tau muaj yuav luag tag tiaj, nyob rau nws yuav tsum tsis txhob yuav muaj khawb thiab stains. Tsis chipping rau ntawm cov npoo. Class II me me tsis xws luag, xws li tsis txaus ceev faj sib tsoo (mus txog 10% yog tso cai), ntau yam chips rau ntug dav thiab ntev. Thaum ua daim hlau qib II tau loj feem pua ntawm cov tawv ntoo thiab loj hais nyob rau hauv qhov loj ntawm lub feedstock.

Chipboard yuav siv tau nyob rau hauv tej kev kawm uas muaj av noo. Txawm li cas los, rau lub hom phiaj no lub feedstock yog tsim nyog los ntxiv molten paraffin los yog paraffin tshuaj, uas yuav txhim kho cov kev stability ntawm cov khoom mus rau dej. Txwv tsis pub, tsub zuj zuj ntawm nws, uas tom qab ua rau o thiab deformation ntawm lub phaj.
