Ungasarudza sei particle board?

Chii chinonzi particle board?

Particle board, inozivikanwawo sechipboard, imhando yebhodhi rekugadzira rinocheka matavi akasiyana-siyana, huni diki dhayamita, huni dzinokura nekukurumidza, sawdust, nezvimwewo kuita zvidimbu zvehumwe saizi, inoaomesa, inosanganisa neadhesive, uye inoatsikirira pasi pehumwe tembiricha nekumanikidza. zvichikonzera kusaenzana kwechikamu.Kunyangwe chidimbu chisiri rudzi rwakafanana rwebhodhi sehuni yakasimba particle board.Solid huni particle board yakafanana mukugadzirisa tekinoroji kune particleboard, asi mhando yayo yakakwira zvakanyanya kupfuura particle board.

Nzira dzekugadzira dze particle board yakakamurwa kuita kupindirana kugadzirwa kweflat kudzvanya nzira, kuenderera mberi kugadzirwa kweextrusion nzira, uye nzira yekutenderedza zvinoenderana neyakasiyana isina chinhu kuumba uye inopisa yekutsikirira maitiro emidziyo.Mukugadzira chaiko, iyo flat yekutsikirira nzira inonyanya kushandiswa.Kupisa kudzvanya inzira yakakosha mukugadzirwa kwechikamu chebhodhi, chinoomesa chinonamira muslab uye chinoomesa slab yakasununguka kuita mukobvu wakatsanangurwa mushure mekumanikidzwa.

Izvo zvinodiwa pakuita ndezvi:

1.) Hunyoro hwakakodzera.Kana hunyoro hwepamusoro huri 18-20%, zvinobatsira kuvandudza simba rekukotama, kusimba kwesimba, uye kutsvedzerera kwepamusoro, kuderedza mukana wekuputika uye delamination panguva yekuburitsa slab.Hunyoro hwemukati hwepakati hunofanirwa kudzika zvakafanira pane dhizaini repamusoro kuchengetedza kusimba kwakakodzera kwendege.

2.)Ikodzera kupisa kudzvanywa kudzvanywa.Dzvinyiriro inogona kukanganisa nzvimbo yekubatana pakati pezvimedu, ukobvu kutsauka kwebhodhi, uye dhigirii rekunamira kuchinjisa pakati pezvimedu.Zvinoenderana neyakasiyana density zvinodiwa zvechigadzirwa, kupisa kudzvanya kudzvanywa kunowanzo 1.2-1.4 MPa.

3.) Tembiricha yakakodzera.Tembiricha yakawandisa haingokonzere kuparara kweurea formaldehyde resin, asi zvakare inokonzeresa kusimba kwekutanga kweiyo slab panguva yekupisa, zvichikonzera marara.

4.) Nguva yakakodzera yekumanikidza.Kana nguva yacho ipfupi, resin yepakati haigone kurapa zvizere, uye kudzoreredza kudzoreredza kwechigadzirwa chakapedzwa munzira yekukora kunowedzera, zvichikonzera kudzikira kukuru kwesimba rekusimba kwendege.Iyo inopisa yakadzvanywa particleboard inofanirwa kutora nguva yekugadziriswa kwemwando kurapwa kuti iwane hunyoro hwakadzikama, uye yobva yachekwa, nekuiswa jecha, uye nekuongororwa kurongedza.

Zvinoenderana nechimiro che particle board, inogona kukamurwa kuita: single-layer structure particle board;Matatu akaturikidzana chidimbu bhodhi;Melamine particle board, oriented particle board;

Single layer particle board inoumbwa nezvidimbu zvehuni zvehukuru hwakafanana zvakatsikirirwa pamwechete.Ibwe rakati sandara uye dense bhodhi rinogona kuvezwa kana laminated nepurasitiki, asi isina kupendwa.Iri ibhodhi rinodzivirira mvura, asi harina mvura.Single layer particle board inokodzera kushandiswa kwemukati.

Iwo matatu-layer particle board anogadzirwa neakaturikidzana ematanda makuru akaturikidzana pakati pezvikamu zviviri, uye akagadzirwa nediki diki-pamusoro-density huni.Iyo yekunze layer ine resin yakawanda kupfuura yemukati layer.Iyo yakatsetseka pamusoro petatu-layer particleboard yakanyatsokodzera kune veneering.

Melamine particle board ipepa rekushongedza rakanyikwa mu melamine iro rinogadzikwa pamusoro pechecheboardboard pasi pekupisa kwakanyanya uye kumanikidzwa.Melamine particle board ine zvivakwa zvisingapindi mvura uye kuramba kukwenya.Kune akasiyana mavara uye maumbirwo, uye mashandisirwo emelamine particle board anosanganisira mapaneru emadziro, fenicha, mawadhiropu, makicheni, nezvimwe.

Zvinoenderana nemamiriro ekunze:

1. Unfinished particle board: sanded particleboard;Unsanded particleboard.

2. Decorative particle board: Impregnated paper veneer particle board;Decorative laminated veneer particle board;Single board veneer particle board;Surface coated particle board;PVC veneer particleboard, nezvimwe

Zvakanakira zve particle board:

A. Iine ruzha rwakanaka rwekunwa uye kuita kwekudzivirira;Particle board insulation uye kunwa kwenzwi;

B. Mukati memukati mune granular chimiro chine mharadzano uye inodzika zvimiro, uye kuita kwese kwese kwakangofanana, asi lateral inotakura simba ishoma;

C. Kumusoro kwechikamu chebhodhi chakati sandara uye chinogona kushandiswa kune dzakasiyana siyana;

D. Panguva yekugadzira particleboard, huwandu hwekunamatira hunoshandiswa hushoma, uye kuchengetedzwa kwezvakatipoteredza coefficient yakakwira.

Zvakaipa zveParticle Board

A. Chimiro chemukati chine granular, zvichiita kuti zviome kukuya;

B. Panguva yekucheka, zviri nyore kukonzera kutsemuka kwemazino, saka mamwe maitiro anoda yakakwirira yekugadzirisa michina zvinodiwa;Haina kukodzera kugadzirwa panzvimbo;

Nzira yekusiyanisa sei kunaka kwe particleboard?

1. Kubva pakuonekwa, zvinogona kuonekwa kuti ukuru uye chimiro chezvimedu zvesawdust pakati pepakati-chikamu chikuru, uye kureba kunowanzova 5-10MM.Kana yakanyanyisa kureba, chimiro chacho chakasununguka, uye kana chiri chipfupi, kupikisa kwekugadzirisa kwakashata, uye iyo inonzi static bending simba haisi kusvika pachiyero;

2. Kunyorova-uchapupu hwekuita kwemapuranga ekugadzira kunoenderana nehuwandu hwavo uye hunyoro-uchapupu agent.Kuanyudza mumvura kuitira hunyoro-ushingi kuita hakuna kunaka.Hunyoro-uchapupu hunoreva kudzivirira hunyoro, kwete kudzivirira mvura.Nokudaro, mukushandiswa kwemangwana, zvakakosha kusiyanisa pakati pavo.Mumatunhu ekuchamhembe, anosanganisira North China, Northwest, uye Northeast China, hunyoro hwemabhodhi hunofanirwa kudzorwa pa8-10%;Nharaunda yekumaodzanyemba, kusanganisira nzvimbo dzemahombekombe, inofanira kudzorwa pakati pe9-14%, kana zvisina kudaro bhodhi rinowanzoita kunwa kwemvura uye deformation.

3. Kubva pakuona kwekupfava kwepamusoro uye kutsvedzerera, zvinowanzodiwa kuti upfuure nepasandpaper polishing process ye200 mesh paunobva mufekitori.Kazhinji, mapoinzi akakwenenzverwa ari nani, asi mune dzimwe nguva, sekunamira mapuranga asingapindi moto, akanyanya kunaka kuti agone kunama zviri nyore.

Kushandiswa kwe particle board:

1. Particle board inoshandiswa sechidziviriro chehuni hwehuni kudzivirira bhodhi rakaoma kubva pakukuvara,

2. Particle board inowanzoshandiswa kugadzira macores uye magonhi ekutsvaira mune yakasimba cores.Particle board yakanaka yegonhi core material nekuti ine yakatsetseka uye yakati sandarara, iri nyore kubatana neganda regonhi, uye yakanaka screw fixation kugona, inoshandiswa kugadzirisa hinges.

3. Particle board inoshandiswa kugadzira sirin'i yenhema nekuti ine yakanaka insulation effect.

4. Particle board inoshandiswa kugadzira fenicha dzakasiyana-siyana, dzakadai sematafura ekupfekedza, matafura, makabati, mawadhiropu, masherufu emabhuku, machira eshangu, nezvimwe.

5. Mukurukuri akagadzirwa ne particle board nekuti anogona kutora ruzha.Ichi ndicho chikonzero zvakare mapuranga emapuranga achishandiswa kumadziro uye pasi pemakamuri ekurekodha, maodhitoriyamu, uye makamuri enhau.
