OSB-phaj: cov raug mob rau tib neeg noj qab haus huv

Ploj mus yog cov hnub thaum twg rau kev tsim kho thiab kho ntawm thaj chaw siv heev dua lwm yam natural thiab cov ntaub ntawv organic - cib, pob zeb, ntoo. Ib txhia ib nrab ib xyoo dhau los, txawm finishing siv ntaub ntawv twb zoo kiag li thiab tsis ua rau ib tug tib gram ntawm tsis ntseeg nyob rau admissibility ntawm lawv cov kev siv. Tam sim no nws yog nce siv nyob rau hauv kev tsim kho ntawm Western technology, yuav siv cov phab ntsa ntub dej, putties thiab ntoo ntoo thaiv phab ntsa. Thiab nws OSB-phaj, kev puas tsuaj rau kev noj qab nyob los ntawm kev siv ntawm ua cov feem ntau rhuab kev sib tham nrog tus neeg zoo tib thiab cov kws txawj.

Yuav ua li cas yog OSB?

Ntawm OSB (oriented strand board) - ib yam khoom tsim los ntawm tej yam ntuj tso raw cov ntaub ntawv (ntoo) los ntawm nias. Yuav kom tsim daim hlau, siv lub zoo feem (chips), ntau zaus nws yog pov tseg los ntawm qhov siv thiab ua lwm yam tsev ntaub ntawv ntawm cov ntoo, thiab tshwj xeeb adhesives.

Qhuav chips impregnated nrog adhesives thiab resins, thiab ces rau kev kawm loj slab, thickness thiab txheej saum npoo av.

Thaum manufacturers siv mas tej ntoo, yog vim li cas nws yog suav tias yog hais tias tus OSB-phaj kev puas tsuaj rau tib neeg noj qab haus huv theem? Tag nrho cov teeb meem ntawm ntxiv tshuaj, namely formaldehyde thiab lwm yam tshuaj lom tshuaj tebchaw uas yog siv los txhim kho qhov kev kawm cov yam ntxwv ntawm lub phaj.

Qhov Cub Xob phaj discord

Ua ntej ntawm tag nrho cov, nws yuav tsum tau hais tias hais tias muaj ntau qhov kev txawv nyob rau hauv ntau cov khoom. Lawv faib yuav siv sij hawm qhov chaw nyob rau ib tug tshwj xeeb marker, tsim los ntawm cov kab mob-epidemiological cov kev pab cuam, thiab yog tus ncaj kev taw qhia rau hauv daim ntawv thov. Yuav kom to taub uas OSB panels muaj teeb meem rau kev noj qab nyob, nws yog tsim nyog los paub dab tsi lawv lub ntsiab sib txawv.

Lawv yog cov uas muaj plaub hom thiab cov cim nrog cov zauv los ntawm 1 mus rau 4, uas ncaj qha qhia yuav ua li cas phaj waterproof thiab check, thiab yog li ntawd ntau npaum li cas adhesives siv rau nws lawm.

Yog li, OSB-1 muaj ib tug tsawg humidity (tsawg tshaj li 20%) thiab siv tau rau hauv kev ua hauj lwm. Phaj OSB-2 - check ntau, nws yuav siv tau rau cladding lug, uas yuav txaus siab load, tiam sis tsuas yog nyob rau hauv qhuav tej yam kev mob. Nyob rau hauv ntau noo vaj tse xws OSB panels muaj teeb meem rau tib neeg noj qab haus huv. OSB-Tyrsoplity OSB-3 thiab 4 muaj lub siab tshaj plaws feem pua ntawm cov nyiaj tau nrog rau kev hwm rau cov noo ib puag ncig thiab siab kev nyuaj siab (15 thiab 12% feem), tab sis qhov feem pua faib toxins muaj ntau dua.

Mus rau lub phaj yog muaj zog opposed ntxooj Qhuav ntxiv thereto ntau dua tus naj npawb ntawm adhesives, nrov heev nthe toxins. Cov ntsiab lus ntawm phenols nyob rau hauv cov khoom ntawm ntoo chips yog nruj me ntsis txwv, thiab lub chaw tsim tshuaj paus yog yuam ua hauj lwm kom meej tus nqi. Rau cov neeg nws yog ib qho tseem ceeb kom paub hais tias lub qhov cub nrog E1 sau tias muaj kev nyab xeeb rau kev siv nyob rau hauv lub tsev. Tab sis OSB chav kawm ntawv E2 muaj zog cov nqi ntawm cov tshuaj lom tebchaw, nws siv yog tas rau cov uas tsis nyob ua vaj tse los yog vaj tse txheej tawv nqaij.

Yog muaj ib qhov txawv nyob rau hauv uas ua?

Nyob rau hauv peb lub teb chaws, nws yog assumed tias tag nrho cov Western - zoo dua, ntau txhim khu kev qha thiab muaj kev nyab xeeb. Nyob rau hauv qhov tseeb, koj yuav tsis yeej ib txwm txiav txim li ntawd, categorically. Qhov tseem ceeb tshaj - nws yog ib lub xub ntiag ntawm daim ntawv pov ntawm cov khoom tsis zoo thiab, ceeb tshaj, raws li lawv. Nws yog nyob rau hauv qhov ntsiab lus teb khoom nyob rau hauv Teb chaws Europe, lub teb chaws USA thiab Canada yog txawv los ntawm lub domestic.

Yuav kom txiav txim seb qhov kev nyab xeeb, nws yog tsim nyog los kawm txog cov cim uas bears lub OSB-phaj. Raug mob rau cov tib neeg noj qab haus huv yuav tsum tau txiav txim coj mus rau hauv lub qhov chaw thiab siv (sab hauv tsev los yog sab nraum zoov).

Nws yuav tsum tau muab sau tseg tias txawm nyob rau hauv Western teb chaws, muaj ntau cov qauv. Qhuav mus txog xws li ib tug theem siab uas rho tawm phenolformaldehyde tshuaj yog tsis tshua.

Nyob rau hauv lub tebchaws United States, Canada, txiav txim siab los txhim tsa ib lub tsev cev txoj kev, ib feem ntawm cov phab ntsa thiab ua hauj lwm pab raws li Perestenko OSB-phaj. Raug mob rau tib neeg noj qab haus huv yog muab rau tus account, thiab rau qhov no kawg, siv ntau hom ntawm cov vuas rau sab hauv thiab sab nrauv siv.

Yog li ntawd, vaj huam sib luag rau cladding facades ntawm lub tsev, ru tsev, pem teb slabs tuab, muaj ib tug ribbed nto thiab yog ib tug me ntsis kim kim.

Nyob rau hauv Teb chaws Europe, cov kuaj tsis ua, tab sis heev nruj me ntsis saib xyuas kev siv ntawm ntau hom ntawm cov phiaj, barring ib co chav kawm ntawv rau qhov kev siv ntawm thaj tsev.

Los ntawm lub cev

Muaj ntau xav li cas mob OSB-phaj yuav ua rau tib neeg noj qab haus huv. Raug pom vapor ob lub qhov muag, faib nws, txawm li cas los, heev loj heev.

Qhov cua nqus tau pa muaj phenol muaj ib tug xov tooj ntawm cov nyom yuav tshwm. Qhov no compound yog carcinogenic, es tag nrho cov tshuab ntawm tib neeg lub cev.

Voos ntawm cov tawv nqaij thiab lub ntsws huam - tsuas yog thawj cov cim qhia ntawm kev qaug tshuaj lom los ntawm tshuaj lom pa. Cob phum chaw nyob rau hauv xws li ib qho chaw, provokes mob loj heev lub plawv kab mob, lub paj hlwb thiab Oncology.

Cov kab mob no yog manifested los ntawm ntau yam mob. Nws yog ib nqi hmoog rau sab hauv ntawm lub chaw, raws li zoo raws li cov ntaub ntawv uas los ntawm lub tsev yog ua, yog hais tias tus neeg hauv tsev neeg feem ntau tsis txaus siab txog koj unwell, xeev siab, kiv taub hau, nkees. Tag nrho cov no tej zaum yog cov tsos mob ntawm lom vapors ntawm phenol-formaldehyde. Yog li ntawd tej zaum kuj OSB-phaj - qhov uas txaus ntshai rau tib neeg noj qab haus huv.

Nrhiav qhov chaw ntawm phenol

Yuav kom ib tug tag nrho cov kev tshawb nrhiav ntawm cov huab cua, raws li zoo raws li sab hauv thiab lwm qhov chaw uas tej zaum yuav muaj tej yam, tsuas yog cov tub txawg ua tau. Lawv txoj hauj lwm yog los mus tsim ib tug tshuaj ntsuam ntawm huab cua thiab impurities nyob rau hauv nws.

Nws yuav tsum tam sim ntawd ua rau ib tug tshwj tseg, uas yog tsis ib txwm lub phaj OSB - lub culprit rau tag nrho cov ills. Uas muaj phenol ntsiab yuav pom txawm nyob rau hauv heev zoo thaum xub thawj siab ib muag tej yam. Nws yuav ua tau rooj tog, textiles (ntaub pua tsev, ua los ntawm cov uas tsis yog-tej yam ntuj tso ntaub ntawv), zoo nkauj khoom thiab txawm yog me nyuam cov khoom ua si.
