Dab tsi yog particle lub rooj tsavxwm?
Particle board, kuj hu uachipboard, yog ib hom kev tsim vaj tse uas txiav ntau yam ceg ntoo, me me txoj kab uas hla, ntoo loj hlob sai, sawdust, thiab lwm yam rau hauv cov khoom ntawm ib qho me me, dries lawv, sib tov nrog cov nplaum, thiab nias lawv nyob rau hauv ib qho kub thiab siab, ua rau tsis sib npaug particle kev npaj.Txawm hais tias particle tsis yog tib hom board li khoom ntoo particle board.Khoom ntoo particle board zoo ib yam li hauv kev siv thev naus laus zis rau particleboard, tab sis nws qhov zoo yog ntau dua particle board.
Cov txheej txheem ntau lawm ntawm particle board tau muab faib ua ntu zus ntawm cov txheej txheem tiaj tiaj, txuas ntxiv ntawm cov txheej txheem extrusion, thiab dov txoj kev raws li lawv qhov sib txawv dawb paug sib sau thiab cov khoom siv kub nias txheej txheem.Nyob rau hauv qhov tseeb ntau lawm, lub tiaj nias txoj kev yog tsuas yog siv.Kub nias yog txheej txheem tseem ceeb hauv kev tsim cov khoom siv particle board, uas ua kom cov nplaum nplaum hauv cov nplais thiab ua kom cov slab xoob rau hauv ib qho tshwj xeeb thickness tom qab raug pressurized.
Cov txheej txheem yuav tsum yog:
1.) Tsim nyog cov dej noo.Thaum cov av noo noo yog 18-20%, nws yog qhov zoo los txhim kho qhov khoov lub zog, tensile lub zog, thiab nto smoothness, txo qhov muaj peev xwm ntawm blistering thiab delamination thaum lub sij hawm unloading ntawm slab.Cov ntsiab lus noo noo ntawm cov tub ntxhais txheej yuav tsum tsim nyog qis dua cov txheej txheej saum npoo kom tswj tau lub dav hlau tensile lub zog.
2.) Tsim nyog kub nias siab.Lub siab tuaj yeem cuam tshuam rau thaj chaw sib cuag ntawm cov khoom, lub thickness sib txawv ntawm lub rooj tsavxwm, thiab qib ntawm cov nplaum hloov ntawm cov khoom.Raws li qhov sib txawv qhov xav tau ntawm cov khoom, qhov kub nias siab feem ntau yog 1.2-1.4 MPa
3.) Qhov kub thiab txias.Qhov kub thiab txias tsis tsuas yog ua rau cov decomposition ntawm urea formaldehyde resin, tab sis kuj ua rau lub zos thaum ntxov solidification ntawm slab thaum cua sov, ua rau cov khoom pov tseg.
4.) Tsim nyog lub sij hawm pressurization.Yog tias lub sijhawm luv luv, cov txheej txheem nruab nrab ntawm cov resin tsis tuaj yeem kho tau tag nrho, thiab elastic rov qab los ntawm cov khoom tiav hauv cov thickness kev taw qhia nce, uas ua rau muaj qhov txo qis hauv lub dav hlau tensile lub zog.Qhov kub pressed particleboard yuav tsum tau mus rau ib lub sij hawm ntawm kev kho cov dej noo kom ua tiav cov ntsiab lus noo noo, thiab tom qab ntawd muab sawn, sanded, thiab tshuaj xyuas rau ntim.
Raws li cov qauv ntawm particle board, nws tuaj yeem muab faib ua: ib txheej txheej particle board;Peb txheej txheej particle board;Melamine particle board, oriented particle board;
Ib txheej particle board yog tsim los ntawm cov khoom ntoo ntawm tib qhov loj nias ua ke.Nws yog ib lub tiaj tiaj thiab ntom ntom uas tuaj yeem ua veneered lossis laminated nrog yas, tab sis tsis pleev xim.Qhov no yog ib tug waterproof particle board, tab sis nws tsis yog waterproof.Ib txheej particle board yog tsim rau kev siv sab hauv tsev.
Peb-txheej particle board yog tsim los ntawm ib txheej ntawm cov ntoo loj loj sandwiched ntawm ob txheej, thiab yog ua los ntawm cov ntoo me me heev.Cov txheej txheej sab nrauv muaj ntau tshaj li cov txheej sab hauv.Qhov du nto ntawm peb-txheej particleboard yog heev haum rau veneering.
Melamine particle board yog ib daim ntawv zoo nkauj uas tau tsau rau hauv melamine uas yog tsau rau saum npoo ntawm particleboard nyob rau hauv qhov kub thiab txias.Melamine particle board muaj cov khoom tsis muaj dej tsis zoo thiab khawb tsis kam.Muaj ntau yam xim thiab textures, thiab daim ntawv thov ntawm melamine particle board muaj xws li phab ntsa panels, rooj tog zaum, wardrobes, chav ua noj, thiab lwm yam.
Raws li qhov xwm txheej saum npoo:
1. Tsis tiav particle board: sanded particleboard;Unsanded particleboard.
2. Kho kom zoo nkauj particle board: Impregnated ntawv veneer particle board;Kho kom zoo nkauj laminated veneer particle board;Ib lub rooj tsavxwm veneer particle board;Nto coated particle board;PVC veneer particleboard, thiab lwm yam
Qhov zoo ntawm particle board:
A. Muaj suab nrov zoo thiab kev ua haujlwm rwb thaiv tsev;Particle board rwb thaiv tsev thiab suab haum;
B. Sab hauv yog cov qauv granular nrog kev sib tshuam thiab staggered cov qauv, thiab kev ua tau zoo nyob rau hauv txhua qhov kev qhia yog qhov zoo ib yam, tab sis lub peev xwm sab nraud yog qhov tsis zoo;
C. Qhov saum npoo ntawm particle board yog tiaj tus thiab tuaj yeem siv rau ntau yam veneers;
D. Thaum lub sij hawm tsim cov txheej txheem ntawm particleboard, tus nqi ntawm cov nplaum siv yog me me, thiab ib puag ncig tiv thaiv coefficient kuj siab.
Disadvantages ntawm Particle Board
A. Cov qauv sab hauv yog granular, ua rau nws nyuaj rau zeb;
B. Thaum lub sij hawm txiav, nws yog ib qho yooj yim ua rau cov hniav tawg, yog li qee cov txheej txheem yuav tsum tau ua cov cuab yeej ua haujlwm siab;Tsis haum rau ntawm qhov chaw tsim khoom;
Yuav ua li cas paub qhov zoo ntawm particleboard?
1. Los ntawm cov tsos, nws tuaj yeem pom tias qhov loj thiab cov duab ntawm cov sawdust hais nyob rau hauv qhov chaw ntawm cov ntoo khaub lig-section yog loj, thiab qhov ntev yog feem ntau 5-10MM.Yog hais tias nws ntev dhau lawm, cov qauv yog xoob, thiab yog tias nws luv dhau, qhov deformation kuj tsis zoo, thiab qhov hu ua static dabtsi yog khoov lub zog tsis yog raws li tus qauv;
2. Kev ua tau zoo ntawm cov ntaub ntawv pov thawj ntawm cov khoom vaj khoom tsev yog nyob ntawm lawv qhov ntom ntom ntom ntom ntom ntom ntom ntom.Soaking lawv hauv dej rau kev ua haujlwm tsis muaj dej noo tsis zoo.Moisture-proof hais txog kev tiv thaiv dej noo, tsis tiv thaiv dej.Yog li ntawd, hauv kev siv yav tom ntej, nws yog ib qho tsim nyog yuav tsum paub qhov txawv ntawm lawv.Hauv cov cheeb tsam sab qaum teb, suav nrog North Tuam Tshoj, Northwest, thiab Northeast Tuam Tshoj, cov dej noo ntawm cov laug cam yuav tsum tau tswj hwm ntawm 8-10%;Cov cheeb tsam yav qab teb, suav nrog thaj chaw ntug dej hiav txwv, yuav tsum tau tswj hwm ntawm 9-14%, txwv tsis pub lub rooj tsavxwm yog nquag nqus dej thiab deformation.
3. Los ntawm qhov pom ntawm qhov chaw flatness thiab smoothness, feem ntau yuav tsum dhau los ntawm cov ntawv xuab zeb polishing ntawm ib ncig ntawm 200 mesh thaum tawm hauv lub hoobkas.Feem ntau, cov ntsiab lus zoo dua yog qhov zoo dua, tab sis qee zaum, xws li cov khoom siv hluav taws xob tiv thaiv hluav taws, lawv zoo heev kom yooj yim glued.
Kev siv ntawm particle board:
1. Particle board yog siv los ua cov khoom siv tiv thaiv rau hardwood flooring los tiv thaiv hardwood board los ntawm kev raug mob,
2. Particle board feem ntau yog siv los tsim cov cores thiab flush qhov rooj hauv cov cores khoom.Particle board yog cov khoom tseem ceeb ntawm lub qhov rooj zoo vim nws muaj qhov du thiab tiaj tus, yooj yim rau kev sib txuas nrog lub qhov rooj ntawm daim tawv nqaij, thiab muaj peev xwm kho cov ntsia hlau zoo, siv los kho cov pob khawm.
3. Particle board yog siv los ua cov ceilings tsis tseeb vim nws muaj kev rwb thaiv tsev zoo.
4. Particle board yog siv los ua ntau yam rooj tog, xws li cov rooj hnav khaub ncaws, cov rooj zaum, cov txee, cov txee dai khaub ncaws, cov phau ntawv, cov khau khib nyiab, thiab lwm yam.
5. Tus hais lus yog ua los ntawm particle board vim nws tuaj yeem nqus suab.Qhov no kuj yog vim li cas particle boards siv rau cov phab ntsa thiab cov plag tsev ntawm cov chav kaw lus, auditoriums, thiab chav xov xwm.
