Kodi kusankha particle board?

Kodi particle ndi chiyani bolodi?

Palinso bolodi, amadziwikanso kutichipboard, ndi mtundu wa bolodi lochita kupanga lomwe limadula nthambi zosiyanasiyana, matabwa ang'onoang'ono, nkhuni zomwe zimakula mofulumira, utuchi, ndi zina zotero. kumabweretsa kusalinganika kwa tinthu.Ngakhale tinthu si mtundu wofanana wa bolodi ngati matabwa olimba tinthu bolodi.matabwa olimba tinthu bolodi ndi ofanana pokonza teknoloji ndi particleboard, koma khalidwe lake ndi apamwamba kwambiri kuposa tinthu bolodi.

Njira zopangira za gulu tinthu anawagawa kukhala pakapita nthawi ya lathyathyathya kukanikiza njira, mosalekeza kupanga extrusion njira, ndi anagubuduza njira malinga ndi osiyana akusowekapo kupanga ndi otentha kukanikiza ndondomeko zida.Pakupanga kwenikweni, njira yokhotakhota yokhazikika imagwiritsidwa ntchito makamaka.Kukanikiza kotentha ndi njira yofunika kwambiri popanga tinthu tating'onoting'ono, yomwe imalimbitsa zomatira mu slab ndikulimbitsa slab kukhala makulidwe odziwika pambuyo popanikizidwa.

Zofunikira za ndondomekoyi ndi:

1.）Chinyezi choyenera.Chinyezi chapamwamba chikakhala 18-20%, ndizopindulitsa kupititsa patsogolo mphamvu yopindika, kulimba kwamphamvu, komanso kusalala kwapamtunda, kuchepetsa kuthekera kwa matuza ndi delamination pakutsitsa slab.Chinyezi cha pachimake chikuyenera kukhala chotsika moyenerera kuposa chapamwamba kuti chikhalebe cholimba champhamvu chandege.

2.) Kuthamanga koyenera kotentha kotentha.Kupanikizika kungakhudze malo olumikizana pakati pa tinthu tating'onoting'ono, kupatuka kwa makulidwe a bolodi, komanso kuchuluka kwa zomatira pakati pa tinthu tating'onoting'ono.Malinga ndi kachulukidwe kosiyanasiyana kwa chinthucho, kukanikiza kotentha nthawi zambiri kumakhala 1.2-1.4 MPa.

3.）Kutentha koyenera.Kutentha kwambiri sikungoyambitsa kuwonongeka kwa urea formaldehyde resin, komanso kumayambitsa kulimba koyambirira kwa slab panthawi yotentha, zomwe zimapangitsa kuti zinyalala ziwonongeke.

4.) Nthawi yoyenera ya pressurization.Ngati nthawi yafupika kwambiri, utomoni wapakati sungathe kuchiza, ndipo kuchira kosalala kwa chinthu chomwe chamalizidwa mu makulidwe kumawonjezeka, zomwe zimapangitsa kuchepa kwakukulu kwa mphamvu zamakokedwe a ndege.Bokosi lopanikizidwa lotentha liyenera kusinthidwa kwanthawi yayitali kuti likhale ndi chinyezi chokwanira, kenako lichekedwe, kuswedwa ndi mchenga, ndikuwunikiridwa kuti liziyika.

Malinga ndi kapangidwe ka bolodi la tinthu tating'onoting'ono, titha kugawidwa m'magulu awiri:Gulu la magawo atatu osanjikiza;Melamine particle board, oriented particle board;

Single wosanjikiza tinthu bolodi wapangidwa matabwa particles wa kukula mbamuikha pamodzi.Ndi bolodi lathyathyathya ndi wandiweyani lomwe limatha kuvekedwa kapena kupangidwa ndi pulasitiki, koma osapaka utoto.Ichi ndi bolodi losalowa madzi, koma silowa madzi.Single layer particle board ndiyoyenera kugwiritsa ntchito m'nyumba.

Gulu la tinthu tating'ono ting'onoting'ono timapangidwa ndi tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta matabwa.Chigawo chakunja chimakhala ndi utomoni wambiri kuposa wamkati.The yosalala pamwamba atatu wosanjikiza particleboard ndi abwino kwambiri veneering.

Melamine particle board ndi pepala lokongoletsera loviikidwa mu melamine lomwe limakhazikika pamwamba pa particleboard pansi pa kutentha ndi kupanikizika.Melamine particle board ali ndi katundu wopanda madzi komanso kukana kukanika.Pali mitundu yosiyanasiyana ndi mawonekedwe, ndipo kugwiritsa ntchito kwa melamine particle board kumaphatikizapo mapanelo a khoma, mipando, zovala, khitchini, ndi zina zotero.

Malinga ndi momwe zinthu ziliri:

1. Zosamalizidwa particleboard: mchenga particleboard;particleboard yopanda mchenga.

2. Kukongoletsa tinthu bolodi: Impregnated pepala veneer tinthu bolodi;Kukongoletsa laminated veneer tinthu bolodi;Single board veneer particle board;pamwamba TACHIMATA tinthu bolodi;PVC veneer particleboard, etc

Ubwino wa particle board:

A. Imayamwidwa bwino komanso imasunga mawu;Kutchinjiriza kwa tinthu tating'onoting'ono ndi mayamwidwe amawu;

B. Mkati mwake ndi mawonekedwe ang'onoang'ono okhala ndi zopingasa ndi zozungulira, ndipo ntchito kumbali zonse ndi yofanana, koma mphamvu yonyamula kumbuyo imakhala yochepa;

C. Pamwamba pa bolodi tinthu ndi lathyathyathya ndipo angagwiritsidwe ntchito veneers zosiyanasiyana;

D. Panthawi yopanga particleboard, kuchuluka kwa zomatira zomwe zimagwiritsidwa ntchito ndizochepa, ndipo chitetezo cha chilengedwe chimakhala chokwera kwambiri.

Kuipa kwa Particle Board

A. Kapangidwe ka mkati kamakhala kakang'ono, zomwe zimapangitsa kuti zikhale zovuta kugaya;

B. Pa kudula, n'zosavuta chifukwa dzino kusweka, kotero njira zina amafuna mkulu processing zida zofunika;Osayenera kupanga pamasamba;

Kodi kusiyanitsa khalidwe la particleboard?

1. Kuchokera ku maonekedwe, zikhoza kuwoneka kuti kukula ndi mawonekedwe a tinthu ta utuchi pakatikati pa gawo la mtanda ndi lalikulu, ndipo kutalika kwake kumakhala 5-10MM.Ngati ndi yayitali kwambiri, kapangidwe kake kamakhala kotayirira, ndipo ngati kakufupi kwambiri, kukana kwa deformation kumakhala koyipa, ndipo zomwe zimatchedwa static kupinda mphamvu sizili zoyenera;

2. Kuchita bwino kwa matabwa opangira chinyezi kumadalira kachulukidwe kawo ndi wothandizira chinyezi.Kuwaviika m'madzi kuti asamachite chinyezi sikuli bwino.Umboni wa chinyezi umanena za kukana chinyezi, osati kuteteza madzi.Choncho, m'tsogolomu, m'pofunika kusiyanitsa pakati pawo.Kumadera akumpoto, kuphatikiza Kumpoto kwa China, Kumpoto chakumadzulo, ndi Kumpoto chakum'mawa kwa China, chinyontho cha matabwa nthawi zambiri chimayenera kuyendetsedwa pa 8-10%;Dera lakumwera, kuphatikizapo madera a m'mphepete mwa nyanja, liyenera kuyang'aniridwa pakati pa 9-14%, mwinamwake bolodi limakhala losavuta kuyamwa ndi kusinthika kwa chinyezi.

3. Kuchokera pakuwona kusalala kwapansi ndi kusalala, nthawi zambiri ndikofunikira kudutsa njira yopukutira sandpaper yozungulira ma mesh 200 pochoka kufakitale.Nthawi zambiri, nsonga zabwino kwambiri, koma nthawi zina, monga kumata matabwa osayaka moto, zimakhala zabwino kwambiri kuti zisamatirike mosavuta.

Kugwiritsa ntchito particle board:

1. Tinthu tating'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'ono timagwiritsidwa ntchito ngati zoteteza ku matabwa olimba kuti zisawonongeke,

2. Tinthu tating'ono ting'onoting'ono nthawi zambiri amagwiritsidwa ntchito popanga zitseko ndi zitseko zolimba.Particle board ndi yabwino pachitseko chifukwa imakhala yosalala komanso yosalala, yosavuta kulumikizana ndi khungu lachitseko, komanso luso lokonza zomangira, zomwe zimagwiritsidwa ntchito kukonza mahinji.

3. Tinthu tating'ono ting'onoting'ono timagwiritsidwa ntchito popanga siling'i zabodza chifukwa ili ndi mphamvu yotsekereza.

4. Particle board imagwiritsidwa ntchito kupanga mipando yosiyanasiyana, monga matebulo ovala, matabuleti, makabati, ma wardrobes, mashelufu a mabuku, zoyika nsapato, ndi zina zambiri.

5. Wokamba nkhani amapangidwa ndi particleboard chifukwa amatha kuyamwa mawu.Ichi ndichifukwa chake ma particle board amagwiritsidwanso ntchito pamakoma ndi pansi pazipinda zojambulira, maholo, ndi zipinda zowonera.
