Plywood lossis Particle Board?

Feem ntau muaj ob txoj hauv kev rau chav ua noj txee lub thawv siv: plywood thiab particle board. Plywood yog ua cov khaubncaws sab nraud povtseg ntawm cov ntoo veneer glued ua ke, hloov pauv cov qoob loo ntawm ntoo kom ruaj khov. Particle board (tseem hu ua rooj tog zaum rooj tog) yog ua los ntawm cov ntoo fibers txuas thiab nias ua ke, qee zaum siv pwm. Txhua cov ntaub ntawv muaj cov txiaj ntsig los xav txog.

Plywood feem ntau xav tias yog cov khoom zoo dua thaum tsim txee. Plywood muaj kev tsim kho siab ntev dua vim tias nws tuav screws thiab lwm yam neeg kho tshuab kom nrawm dua. Nws muaj cov khoom nyhav zoo dua qub thiab cov nplais shearing (lub ntsiab lus nws resists rub lub zog thiab ib sab mus rau sab nraud) thiab tau txais txiaj ntsig me me hauv kev ua kom muaj zog (muaj peev xwm tiv taus hnyav), Chen hais, Rebon cov neeg ua haujlwm uas muaj 10 xyoo dhau los ua tus kws ntoo. Cov. Plywood kuj nyhav tsawg dua ntawm cov khoom me me, uas tuaj yeem yog qhov tseem ceeb thaum dai cov txee loj. Tsis tas li, plywood tuav cov kua nplaum sib xyaw ua ke zoo dua li cov pawg ua ke thiab yog qhov cuam tshuam ntau dua rau cov hniav thiab khawb.

Particle board nws tus kheej muaj qhov zoo, suav nrog ntau dua qhov ntev qhov kev ruaj ntseg: nws tsis ua kom yuag vim qhov ntsuas kub hloov pauv thiab lwm yam kev hloov ntawm ib puag ncig. Feem ntau qhov tshwj xeeb, qhov pawg thawj coj saib nqi tsawg dua plywood. Particle board feem ntau yog ua los ntawm kev txiav ntoo uas suav tias yog khib nyiab. Ntau cov plywood manufacturers kuj ua cov pawg tswj hwm los ntawm cov khoom seem. Vim tias qhov no, particle board tsis tshua kim.

Ib qho kev poob qis rau cov pawg me me yog qhov nws tsis muaj dej noo tiv taus. Yog tias noo noo nqus tau los ntawm cov nplej thaum kawg, pawg tswj hwm yuav ya raws - piv txwv li, yog tias cov dej saum npoo av tau chwv nrog rau hauv qab npoo tsis tiav ntawm lub thawv ntawv. Txhawm rau daws qhov teeb meem no, Rebon ntim cov xaus ntawm txhua qhov teeb meem pawg thawj coj nrog ntug banding. Lub chaw nruab khoom kuj tseem yuav kaw cov kab hauv qab ntawm cov thawv ntawv nrog lub tsho meej thaum txhim kho lawv. Plywood, txawm tias ntau dua cov dej tsis haum, kuj tseem tsis tau ruaj khov hauv cov dej ntub tsis tu ncua.

Ib qho tseem ceeb, plywood thiab particle board tuaj yeem sib txawv heev hauv qhov ua tau zoo, ua rau nws nyuaj hais tias ib qho yeej ib txwm zoo dua dua lwm tus. Qhov zoo ntawm plywood nyob ntawm tus naj npawb ntawm plies thiab tuab ntawm ntoo. Tsawg tus plies tsis tshua ruaj khov, yog li zoo plywood yuav muaj ntau plies. Qhov zoo kuj tseem nyob ntawm seb cov plies muaj qhov glued ua ke zoo npaum li cas. Tsawg-plywood yuav muaj qhov khoob, ua rau nws tsis tshua ntseeg. Rau lub ntsej muag-daim ntaub thaiv txee, ntoo ib nrab plywood siv rau sab, sab saum toj, thiab hauv qab vim hais tias tus ncej ntxiv lub zog rau lub thawv zuag qhia tag nrho; rhawv yog 3/4 nti plywood. Yog li, txawm hais tias plywood yog zoo dua nyob rau hauv dav dav, muaj ntau yam mob nyob qhov twg particle board yuav ua tau zoo txaus rau kev txiav txim cov nqi txuag, hais tias Linda.

Cov pawg pawg zoo nyob ntawm qhov loj me ntawm cov khoom uas ua nws, cov kua nplaum uas tuav nws ua ke, thiab qhov ceev ntawm pawg thawj coj. Vim tias cov ntawv sau particle tuaj yeem tsim tawm ntawm cov pov tseg ntau ntawm cov ntoo, nws qhov zoo tuaj yeem sib txawv me ntsis. Cov tso tawm me me ua rau lub rooj tsavxwm zoo dua, muaj zog dua, thiab hnyav dua. Ib qho zoo tshaj plaws ntawm cov particle board yog nruab nrab cov kab hluav taws xob fiberboard (MDF), nws yog qhov ua tau zoo, tab sis tuaj yeem ua hnyav, ua rau nws nyuaj rau dai cov txee loj. Particle board kuj yooj yim gouged lossis khawb; txawm li cas los xij, qhov no tsis yog qhov teeb meem ntau yog tias nws muaj kev tiv thaiv los ntawm ntoo veneer lossis laminate.

Vim tias plywood zoo dua rau cov pawg me hauv ntau qhov, nws yog feem ntau qhov kev xaiv zoo dua yog tias tus nqi tsis yog qhov teeb meem. Txawm li cas los xij, qhov tseeb hais tias particle board tsis tshua kim ua rau nws xaiv qhov tsim nyog hauv ntau lub sijhawm. Yog tias lub txee loj thiab yuav dai, plywood yuav yog qhov kev xaiv zoo dua vim tias nws yog sib dua. Feem ntau ntawm lwm qhov xwm txheej, pawg thawj coj saib yuav ua haujlwm yuav luag zoo li plywood. Thaum kho dua tshiab, nco ntsoov xav txog cov txiaj ntsig ntawm plywood tiv thaiv cov kev txwv ntawm koj cov nyiaj txiag los txiav txim siab seb qhov kev xaiv twg zoo tshaj.
