Ntau tus neeg siv khoom tsis nkag siab zoo dab tsi yog qhov zoo dua - OSB lossis chipboard, lawv txawv li cas thiab yuav tso dab tsi rau hauv pem teb. Lub caij no, qhov sib txawv ntawm OSB thiab cov laug cam yog qhov tseem ceeb heev. Nws yog ib qho tsim nyog yuav tau ua tib zoo nkag siab tias yam twg muaj zog thiab muaj zog dua, muaj teeb meem ntau dua thiab pheej yig dua.
Dab tsi yog qhov muaj zog?
Lub zog ntawm cov ntoo sib xyaw tau txiav txim siab los ntawm ntau qhov ntsuas sib cuam tshuam:
- khoov lub zog txwv;
- elastic modulus;
- ruaj khov npaum li cas.
OSB muaj cov chips loj. Lawv tau qhia meej meej thiab tsim cov qauv uas raug xaj. Yog li, hauv kev xav, nws tuaj yeem cia siab tias cov khoom siv no yuav muaj zog dua li lub rooj tsav xwm ib txwm muaj. Tab sis qhov pom tseeb hauv thev naus laus zis tsis ua haujlwm ib txwm, thiab yog li ib qho yuav tsum xub ua tib zoo mloog cov lus qhia ntawm lub xeev cov qauv. GOST sau tseg tias rau chipboard cov qauv hauv qab no yuav tsum tau muab:
- khoov tsis kam - tsis phem tshaj 11 MPa;
- elastic modulus - tsawg kawg 1600 MPa;
- muaj peev xwm tuav cov fasteners - ntawm 35 txog 55 N / m.
Rau OSB, txawm tias qhov tsawg kawg nkaus dabtsi yog khoov lub zog nyob rau hauv qhov kev coj ua ntev yog qhov tseem ceeb dua - los ntawm 18 MPa. Nws tuaj yeem ncav cuag 20 MPa. Lub zog khoov hla txoj kab uas hla, txawm li cas los xij, yog me ntsis tsawg dua (tsis pub ntau tshaj 10 MPa, thiab txawm tias 9 MPa sib raug rau tus qauv ntsuas).
Tab sis raws li txhua lwm yam txheej txheem, OSB yeej yeej . Yog li, qhov hloov pauv hloov pauv hauv lub dav hlau ntev tsis qis dua 3500 MPa, thiab txawm tias nws tus nqi qis dua li ntawm chipboard, tus nqi hauv dav hlau hla yog qhov ncaj ncees; ntxiv rau, txawm tias feem ntau cov tuam txhab tsim khoom nruab nrab muab lub zog nrawm ntawm tsawg kawg 80-90 N / m.
Kev tiv thaiv cov ntaub ntawv kom ya raws
Kev siv thev naus laus zis zoo ib yam ntawm kev tso tawm tsis tso cai, ua rau suav nrog qhov ntsuas zoo ib yam ntawm kev tiv thaiv ya raws. Lawv pom tau zoo dua hauv OSB. Tab sis koj yuav tsum nkag siab tias muaj ntau pawg ntawm cov khoom siv ntawd ib zaug. Tsis yog txhua ntawm lawv tshwj xeeb tshaj yog tiv taus dej nkag mus.
Txawm li cas los xij, nrog chipboard, txhua yam yog qhov phem dua - ib qho ntawm nws ntau yam thiab hom tsis tshua muaj neeg tsis zoo los ntawm dej noo. Txawm tias chipboard tsuas yog tiv thaiv los ntawm zaj duab xis nyias.
Dab tsi ntxiv yog qhov sib txawv ntawm OSB thiab chipboard?
Particleboard yog qhov pheej yig dua qhov kev xaiv. tab sis coj mus rau hauv tus account qhov tsis muaj zog ntawm cov khoom siv no (thiab siab dua txhua yam tsis zoo ntawm cov yam ntxwv yam ntxwv), nws qhov kev xaiv yog qhov ncaj ncees tsuas yog hauv qhov xwm txheej hnyav tshaj plaws . Kev ntseeg tau tag nrho ntawm chipboard yog qhov tsawg heev. Yog lawm, ob qho khoom siv - nrog kev ua tau zoo txaus rau thev naus laus zis - yuav tsis delaminate. Tab sis tseem, cov ntaub ntawv uas tsis sib xws ntawm cov chipboard yog nquag ntog ntawm qhov kawg.
Qhov sib txawv tseem ceeb ntawm ob qhov kev txhawj xeeb txheej txheem. Ob lub chipboard thiab cov txheej txheem tuaj yeem tsis muaj teeb meem:
- txiav;
- laum;
- zom.
Tab sis cov khoom siv chipboard sib tsoo, thiab yog li ntawd nws cov txheej txheem tsis yooj yim dua. Tom qab nws xaus, ntau cov khib nyiab yuav tsum raug tshem tawm. Thiab nws tsis yooj yim sua kom ntswj ntsia hlau lossis ntsia hlau ob zaug hauv tib lub qhov uas tsis ntxiv cov tshuaj epoxy.
Kev sib piv ntawm chipboard thiab OSB tuaj yeem ua tau hauv lwm qhov kev ntsuas . Kev sib txuas ntawm cov plaub hau raws li thawj thev naus laus zis yuam kom siv cov tshuaj loj dua. Yog li ntawd, kev siv cov pa lom yuav siab dua.
Hauv qhov kev nkag siab no, peb tuaj yeem hais khov kho tias chipboard muaj teeb meem ntau dua hauv khub no, thiab OSB, ntawm qhov tsis sib xws, muaj kev nyab xeeb dua . Thiab koj yuav tsum tsis txhob saib xyuas qhov kev pheej hmoo zoo li no. Tom qab tag nrho, peb tsis tham txog qee yam ntawm cov ntoo ntoo, tab sis hais txog formaldehyde, uas tau lees paub tias yog ib yam tshuaj lom tshaj plaws uas siv hauv kev ua ntoo. Ib puag ncig zoo yog qhov tseem ceeb tshwj xeeb thaum nws los txog rau kev siv cov qauv hauv cov menyuam chav, chav ua noj, chav dej thiab chav pw.
Qhov sib txawv tseem ceeb cuam tshuam txog qhov tsos. Oriented strand cov ntaub ntawv tau ntev tau lees paub los ntawm txhua tus kws tshaj lij raws li kev daws teeb meem zoo nkauj dua . Los ntawm nws qhov kev ntxhib los mos, nws yog ze dua rau ntoo ntuj. Feem ntau cov txheej no yog siv los kho cov phab ntsa sab hauv thiab muab faib "hauv qab cov kua roj vanish". Tab sis chipboard tuaj yeem siv rau kev kho kom zoo nkauj tsuas yog thaum siv txheej txheej (zaj duab xis tshwj xeeb).
Qhov ntom thiab qhov hnyav ntawm ob qho qauv tsim yog kwv yees tib yam . Ib yam nkaus, kev tiv thaiv kab thiab kab mob me me yog zoo ib yam. Yog tias peb tseem piv nws nrog plywood, tom qab ntawd cov lus qhia ua haujlwm tau hloov pauv kom pheej yig dua.
Ntau yam ntaub ntawv tau siv hauv kev tsim cov chipboard, suav nrog sawdust . Oriented strand laug cam tau tsim nruj me ntsis raws li cov khoom lag luam zoo. Cov plaub hau lawv tus kheej tsis tau teeb tsa "tsuas yog nyob ntawm qhov xwm txheej", tab sis nyob rau hauv qhov kev txiav txim zoo.
Qhov kev xaiv zoo tshaj yog dab tsi?
Coj mus rau hauv tus account txhua yam uas tau hais, nws tau pom meej tias nws yog OSB uas raug tshaj plaws los tso rau hauv pem teb. Particleboard tsis muaj dab tsi ntau tshaj li qhov kev xaiv pom zoo ntawm pob nyiaj siv nruj lossis hauv cov tsev nruab nrab. Ob qho khoom siv tuaj yeem tso tawm ob qho tib si ntawm lub crate thiab ntawm cov qhob screed, yog li ntawd, hauv qhov no, lawv muaj ntau yam sib npaug.
Tab sis nws tseem tsim nyog sau cia tias nws muaj peev xwm tso chipboard rau ntawm cov cav tsuas yog nrog qhov tsawg kawg nkaus nrug ntawm cov tuav; nyob rau hauv cov ntaub ntawv ntawm lub hauv paus hauv paus, tsis muaj teeb meem zoo li no - kev ua kom nrawm yog siv cov dowels, thiab lub qhov yog ua ua ntej nrog lub perforator.
Tab sis txawm tias txiav txim siab yuav luag txhua qhov kev xaiv tsis meej hauv kev nyiam ntawm OSB, nws yog qhov tsim nyog kom nkag siab tias cov khoom siv no tuaj yeem muaj qhov sib txawv tseem ceeb. Rau kev kho kom zoo hauv pem teb, nws raug nquahu kom siv hom ntoo. Ua kom tiav cov khoom tiaj tus yuav tsum tau muab tso nrog qhov sib txawv, thiab tom qab ntawd saturated nrog sealant. OSB-1, OSB-2 tau tsim los ua haujlwm hauv chav nrog cov av qis, qhov uas tsis muaj cov khoom siv tseem ceeb . Ntau yam ntxiv nyob rau hauv cov nqe lus ntawm kev tiv thaiv kom ya raws thiab cov khoom siv dag zog, tab sis kuj tseem kim dua, OSB-3 thiab OSB-4 slabs.
Cov qauv txheej txheem feem ntau raug coj mus ua ntej ua kom haum kab rov tav . Tab sis nyob rau hauv cov xwm txheej zoo, lawv kuj tseem siv rau pem hauv ntej ua tiav. Cov qib yooj yim ntawm cov subfloors hauv chav qhuav feem ntau cuam tshuam nrog kev siv OSB-2. Thiab cov slab ntawm thawj qeb yog qhov siv tau rau lub qab nthab thiab phab ntsa hauv chav sov (rhaub).
Chipboard thiab OSB tuaj yeem siv sib npaug hauv qab cov vuas hauv chav dej lossis hauv pas dej - yog tias lawv tsis muaj dej. Txawm li cas los xij, muab qhov tseem ceeb ntxiv hydrophobicity ntawm cov khoom thib ob, qhov kev xaiv yog qhov tseeb. Yog tias tsis kho, txheej txheej tuaj yeem kis tus kab zes ntawm cov pwm thiab lwm yam kab mob me me. Tib yam kev xav tau siv rau kev ua tiav:
- chav ua noj;
- qhib lub sam thiaj;
- chav da dej;
- txoj kev;
- nthab;
- pem teb thiab phab ntsa hauv cellars, hauv qab daus, hauv qab daus;
- tso;
- da dej.
OSB yog qhov zoo rau kev teeb tsa hauv qab no:
- ntaub pua plag;
- linoleum;
- laminate;
- parquet;
- ntau hom parquet boards.
Tseem ceeb: rau thaj chaw nyob, txheej txheej E1 zoo tshaj plaws. Nws yog pab pawg no uas muaj kev nyab xeeb tshaj plaws ntawm txhua cov ntaub ntawv nti. OSB vaj huam sib luag tsim nyog tsis yog rau hauv pem teb, tab sis kuj rau phab ntsa. Hauv qhov kev nkag siab no, lawv zoo dua li cov phab ntsa ntub dej. Cov khoom siv no yog siv rau:
- txuas hniav hauv ob sab phlu;
- upholstery nrog ntau yam vaj huam sib luag;
- staining nrog txhua yam xim (tsis kho nrog putty, tshwj tsis yog pob qij txha hauv ib qho chaw).
