Chipboard Ntom Ntom: 16-18 Hli Thiab Lwm Qhov Ntau Thiab Tsawg. Nws Nyob Ntawm Dab Tsi Thiab Yuav Txiav Txim Siab Qhov Ntom Ntawm Kg Ib M3 Li Cas?

Chipboard txheej yog tsim los ntawm cov khib nyiab los ntawm cov ntoo thiab cov chaw tsim khoom ntoo. Qhov sib txawv tseem ceeb hauv cov yam ntxwv ntawm lub cev thiab lub tshuab yog qhov loj ntawm chipboard, nws cov tuab thiab ntom. Nws yog qhov txaus siab tias cov khoom lag luam ntawm qhov zoo tshaj plaws tuaj yeem hla dhau ntoo hauv qee qhov tsis. Cia peb ua tibzoo saib ntawm txhua yam hais txog cov khoom ntom ntom ntom ntom.

Nws nyob ntawm dab tsi?

Qhov ntom ntawm chipboard ncaj qha nyob ntawm qhov zoo ntawm cov khoom siv rau lub hauv paus. Nws tuaj yeem yog me me - 450, nruab nrab - 550 thiab siab - 750 kg / m3. Qhov xav tau ntau tshaj yog cov rooj tog chipboard. Nws muaj cov qauv zoo thiab ua kom zoo zoo nplaim, qhov ntom yog tsawg kawg 550 kg / m3.

Tsis muaj qhov tsis xws ntawm cov txheej no. Lawv tau siv rau kev tsim cov rooj tog, kho kom zoo nkauj thiab kho kom zoo nkauj sab nrauv.

Nws yuav yog dab tsi?

Chipboard txheej tau ua los ntawm ib-, ob-, peb- thiab ntau txheej. Qhov nrov tshaj plaws yog peb-txheej, vim muaj cov coarser chips sab hauv, thiab ob txheej sab nraud yog cov khoom me me. Raws li txoj hauv kev ua cov txheej txheej saum toj kawg nkaus, cov nplais thiab cov nplais tsis muaj qhov txawv yog qhov txawv. Nyob rau hauv tag nrho, peb qib ntawm cov khoom siv tau ua, uas yog:

• txheej sab nrauv yog txawm thiab ua tib zoo xeb, tsis muaj daim tawv nqaij, khawb lossis khawb;
• kev tshem tawm me me, khawb thiab nti raug tso cai tsuas yog nyob ntawm ib sab;
• kev tsis lees paub raug xa mus rau qib peb; ntawm no lub chipboard yuav muaj tuab tuab tsis sib xws, khawb tob, tshem tawm thiab tawg.

Chipboard tuaj yeem yuav luag txhua qhov tuab. Feem ntau siv tsis tau yog:

• 8 hli - nqaim nqaim, nrog ntom ntawm 680 txog 750 kg ib m3; lawv tau siv hauv kev tsim cov rooj tog hauv chaw ua haujlwm, cov khoom dai kom zoo nkauj;
• 16 hli - kuj tseem siv rau kev tsim cov rooj tog hauv chaw ua haujlwm, rau cov plag tsev uas ua haujlwm pab txhawb rau pem teb yav tom ntej, rau kev faib ua haujlwm sab hauv;
• 18 hli - txee rooj tog tau ua nrog nws;
• 20 hli - siv rau hauv av ntxhib;
• 22, 25, 32 mm - ntau lub tabletops, qhov rai qhov rais, txee tau ua los ntawm cov ntawv tuab dua - uas yog, ib feem ntawm cov qauv uas ua rau lub nra hnyav;
• 38 hli - rau chav ua noj txee thiab txee txee.

Tseem ceeb! Qhov me me ntawm cov tuab tuab, qhov siab dua nws qhov ntom yuav yog, thiab hloov pauv, ntau dua qhov tuab sib xws rau qhov ntom ntom.

Raws li ib feem ntawm chipboard muaj formaldehyde lossis cov khoom siv dag, yog li ntawd, raws li tus nqi ntawm cov khoom tso tawm los ntawm 100 g ntawm cov khoom, cov phaj tau muab faib ua ob pawg:

• E1 - cov ntsiab lus ntawm cov khoom hauv kev sib xyaw tsis pub tshaj 10 mg;
• E2 - tso cai cov ntsiab lus formaldehyde txog 30 mg.

Particleboard ntawm chav kawm E2 feem ntau tsis tau ua, tab sis qee qhov chaw tsim khoom lag luam tso cai rau cov khoom siv no muag, thaum cuam tshuam cov cim lossis tsis thov nws. Nws tuaj yeem txiav txim siab chav kawm ntawm formaldehyde resins tsuas yog hauv chav kuaj.

Yuav txiav txim siab li cas?

Heev feem ntau, cov neeg tsim khoom tsis ncaj ncees txog kev tsim khoom ntawm chipboard, ua txhaum cov txheej txheem tsim khoom tsim tawm. Yog li ntawd, ua ntej yuav khoom, koj yuav tsum txheeb xyuas nws qhov zoo. Txhawm rau txiav txim siab qhov ua tau zoo, cov hauv qab no yuav tsum raug txiav txim siab:

• yuav tsum tsis muaj ntxhiab tsw nyob deb li ntawm ib 'meter' ntawm cov khoom; yog tias muaj tam sim no, qhov no qhia txog qhov ntau ntawm cov resins hauv cov muaj pes tsawg leeg;
• yog tias ib yam khoom tuaj yeem nyam mus rau sab yam tsis muaj kev siv zog, nws txhais tau tias chipboard tsis zoo;
• nyob rau hauv tsos, tsim yuav tsum tsis zoo li overdried;
• muaj ntug tsis xws luag (nti), uas txhais tau tias cov khoom raug txiav tsis zoo;
• txheej saum npoo yuav tsum tsis txhob tev tawm;
• xim tsaus qhia tias muaj cov tawv ntoo loj nyob hauv qhov muaj pes tsawg leeg lossis cov phaj tau hlawv;
• ib qho xim liab yog qhov zoo rau cov khoom siv los ntawm cov hlawv hlawv;
• yog tias chipboard tsis zoo, tom qab ntawd yuav muaj ntau xim hauv ib pob; cov khaub ncaws zoo ib yam thiab lub teeb sib haum rau qhov ua tau zoo;
• hauv ib pob, txhua txheej yuav tsum zoo ib yam thiab tuab.
