5 Lowetsani Zowona Zomwe Muyenera Kudziwa Zokhudza Kanemayo Akukumana ndi Plywood

plywood ndi chiyani?

Plywood imatha kugawidwa kukhala plywood yofewa (masson pine, larch, red pine, etc) ndi hardwood plywood (bass nkhuni, birch, phulusa, ndi zina).

Pakuwona kukana madzi, plywood ikhoza kugawidwa m'magulu anayi:

Kalasi I - Plywood yolimbana ndi nyengo komanso madzi otentha (WBP), pogwiritsa ntchito zomatira za phenolic resin.Oyenera madera akunja monga ndege, zombo, ngolo, kulongedza katundu, konkire formwork, hydraulic engineering, ndi malo ena okhala ndi madzi bwino kukana ndi kukana nyengo.

Class II chinyezi chosagwira plywood (MR), yokhoza kumizidwa m'madzi ozizira kwakanthawi kochepa, yoyenera kugwiritsidwa ntchito m'nyumba pansi pamikhalidwe yabwinobwino.Amapangidwa polumikizana ndi urea formaldehyde resin kapena zomatira zina zokhala ndi zofanana.Amagwiritsidwa ntchito ngati mipando, kulongedza, komanso kumanga wamba Cholinga cha zomangamanga.

Class III water resistant plywood (WR), yomwe imatha kuviikidwa m'madzi ozizira, imatha kupirira nyengo yayifupi ya kumizidwa m'madzi otentha, ndipo imakhala ndi antibacterial properties, koma imakhala yosagonjetsedwa ndi kuwira.Amapangidwa ndi urea formaldehyde resin kapena zomatira zina zomwe zili ndi zofanana.Amagwiritsidwa ntchito kukongoletsa mkati ndi kulongedza zamagalimoto, zombo, mipando, ndi nyumba.

Class IV non chinyezi resistant plywood (INT), yogwiritsidwa ntchito m'nyumba nthawi yabwinobwino, imakhala ndi mphamvu yomangirira.Amapangidwa pomanga ndi guluu wa nyemba kapena zomatira zina zomwe zili ndi zofanana.Amagwiritsidwa ntchito kwambiri pakuyika komanso pazolinga zonse.Bokosi la tiyi liyenera kupangidwa ndi plywood ya glue

Plywood yomwe imagwiritsidwa ntchito popanga filimu ya konkriti yoyang'anizana ndi plywood ndi ya plywood ya Class I yokhala ndi nyengo yayitali komanso kukana madzi, ndipo zomatira ndi zomatira za Phenolic resin zimakonzedwa makamaka kuchokera ku poplar, birch, pine, bulugamu etc.

1. Mafilimu amayang'anizana ndi mapangidwe a plywood apanyanja ndi mawonekedwe ake

(1)Kapangidwe

Plywood yamatabwa yomwe imagwiritsidwa ntchito popanga mawonekedwe nthawi zambiri imakhala ndi zigawo zosamvetseka monga 5, 7, 9, ndi 11, zomwe zimamangidwa ndikuchiritsidwa ndi kukanikiza kotentha.

Mtundu.Maonekedwe a zigawo zoyandikana amakhala perpendicular kwa wina ndi mzake, ndipo kawirikawiri mawonekedwe a mawonekedwe a kunja kwa bolodi amafanana ndi kutalika kwa plywood pamwamba.Choncho, njira yayitali ya plywood yonse ndi yolimba, ndipo njira yachidule ndi yofooka.Chidwi chiyenera kuperekedwa mukachigwiritsa ntchito.

(2) Mafotokozedwe

Mafotokozedwe ndi miyeso ya filimu yoyang'anizana ndi plywood ya formwork

2. Filimu yoyang'anizana ndi plywood bmagwiridwe antchito ndi kubereka mphamvu

(1) Kuchita kwa mgwirizano

Zomatira za plywood zomwe zimagwiritsidwa ntchito mufilimu yoyang'anizana ndi plywood yam'madzi ndi makamaka phenolic resin.Zomatira zamtunduwu zimakhala ndi mphamvu zomangirira komanso kukana madzi, Kutentha kwabwino kwambiri komanso kukana dzimbiri, kukana madzi otentha komanso kukhazikika.

Bond Strength Index Makhalidwe a Filimu Yoyang'anizana ndi Marine Plywood

Mukamagula plywood yopangira konkriti, muyenera kuyang'ana kaye ngati ili ya plywood ya Class I,

Onani ngati gulu la plywood lagwiritsa ntchito zomatira za phenolic resin kapena zomatira zina zomwe zili ndi zofanana.Ngati kuyesedwa pamene mikhalidwe ili yochepa ndipo kuyesa mphamvu zomangira sikungathe kuchitidwa, kachidutswa kakang'ono kakhoza kusiyanitsa mofulumira ndi madzi otentha.

Gwiritsani ntchito kachidutswa kakang'ono ka masentimita 20 ocheka kuchokera ku plywood ndikuphika m'madzi otentha kwa maola awiri.Kugwiritsira ntchito phenolic resin ngati chidutswa choyesera sichidzasungunuka mutatha kuphika, pamene chidutswa choyesera chimagwiritsa ntchito pulse formaldehyde resin monga zomatira zidzasungunuka mukaphika.

(2) Kukhala ndi mphamvu

Mphamvu yonyamula katundu ya plywood yamatabwa imagwirizana ndi makulidwe ake, mphamvu yopindika yokhazikika, komanso modulus yotanuka.

Miyezo yokhazikika yamphamvu yopindika komanso zotanuka modulus yotsekera plywood (N/mm2)

Kumanga cpncrete shuttering plywood akhoza kugawidwa mu shuttering plywood wamba ndi film faced plywood .

Pothira zida za konkriti pogwiritsa ntchito plywood yotsekera, monga milatho, mizati, ndi mizati, kuuma kokhazikika ndi manambala kuyenera kukumana, ndiyeno kukongoletsa imvi kuyenera kugwiritsidwa ntchito. pamwamba.Amagwiritsidwa ntchito makamaka m'nyumba za anthu wamba komanso mafakitale.

Mafilimu akuyang'anizana ndi plywood ya m'madzi amapangidwa ndi kuphimba pepala la laminnation pa bolodi yabwino yopangira .Pamwamba pa filimuyi yomwe ikuyang'anizana ndi plywood ndi yosalala, yowala, yopanda madzi, komanso yopanda moto, yokhala ndi kukhazikika kwabwino kwambiri (kukana nyengo, kukana kwa dzimbiri, kukana kwa mankhwala) ndi mphamvu yoletsa kuyipitsa.

Chifukwa chiyani?filimu yolimbana ndi plywoodokwera mtengo kwambiri poyerekeza ndi wambakutseka plywoodformwork?

1. Mapepala a mkuwa omwe amatumizidwa kunja omwe amapangidwa ndi plywood ali ndi makhalidwe osalala kwambiri, osalala bwino, komanso kugwetsa kosavuta.Pambuyo pakugwetsa, pamwamba pa konkire ndi yosalala, kupewa kujambula kwachiwiri, kuchepetsa ndalama, ndikufupikitsa nthawi yomanga.Amadziwika ndi kulemera kopepuka, kudula kolimba, kamangidwe kabwino kamangidwe, komanso liwiro la zomangamanga.

2. Firimuyi ikuyang'anizana ndi plywood ndi zinthu zotentha kwambiri komanso zowonongeka, zomwe zimakhala zowuma, zolimba kwambiri, komanso zimakhala zolimba.Mphamvu yopindika yosasunthika ndiyoposa kuwirikiza kawiri kuposa yamatabwa.

3.) Kukana madzi mwamphamvu.Pakupanga, wosanjikiza wa utomoni wa phenolic umagwiritsidwa ntchito ngati wosanjikiza wowotchera wotentha popanda kuwiritsa guluu kwa maola 5, zomwe zimapangitsa kuti zikhale zovuta kupundutsa gululi pakukonza konkire.

4.) Thermal conductivity ndi yaying'ono kwambiri kusiyana ndi nkhungu zachitsulo, zomwe zimapindulitsa pa kutentha kwapamwamba m'nyengo yachilimwe ndi yomangamanga.

5. Chiwongoladzanja cha chiwongoladzanja ndi chachikulu kuposa cha plywood yotsekera, ndipo chiwongoladzanja chonsecho chikhoza kufika nthawi 12-18.

6.) Kukana kwa dzimbiri: sikuipitsa pamwamba pa konkire.

7.) Chopepuka: Chosavuta kugwiritsa ntchito pomanga nyumba zapamwamba komanso kumanga mlatho.

8.) Ntchito yomanga bwino: Ntchito ya misomali, macheka, ndi kubowola ndi yabwino kuposa ya nsungwi plywood ndi zitsulo zazing'ono.Itha kusinthidwa kukhala ma templates osiyanasiyana malinga ndi zofunikira zomanga.

9.) Mtundu waukulu: Mawonekedwe apamwamba kwambiri ndi 2440 * 1220 ndi 915 * 1830mm, kuchepetsa chiwerengero cha olowa ndikuwongolera bwino kwa chithandizo cha formwork.Palibe kuwombana, palibe mapindikidwe, palibe kusweka.

10.) Kutha kunyamula katundu, makamaka kukana kuvala bwino pambuyo pa chithandizo chapamwamba, ndipo chitha kugwiritsidwanso ntchito kangapo;

11.) zinthu zopepuka, 18mm makulidwe filimu anakumana plywood, ndi unit kulemera kwa 50kg zosavuta kunyamula, okwana ndi ntchito.

Kodi kuweruza khalidwe la filimu anakumana plywood?

Choyamba, yang'anani mawonekedwe ndi mtundu wa template.Maonekedwe a filimu yoyang'anizana ndi plywood nthawi zambiri amakhala okhazikika, okongola, komanso owolowa manja.

M'malo mwake, filimuyo anakumana plywood ndi khalidwe osauka ndi chisokonezo kapangidwe.Mukakumana ndi plywood yoyang'anizana ndi filimu yokhala ndi mitundu yakuda pamwamba ndi zigawo za utoto wokhuthala, ndizotheka kuti wopanga adabisa dala zolakwika za plywood.

Kachiwiri, gwiritsani ntchito njira yopondapo kuti muwone ngati kulimba kuli kokwanira.Tikhoza mwachisawawa kusankha filimu anakumana Marine plywood.Anthu akhoza kuyimirira ndi kupondapo.Ngati phokoso likuwoneka bwino kwambiri, limasonyeza kuti khalidweli ndi lochepa.Kenako, kudula mu mawonekedwe a matabwa Mzere ndi kuyendera zolakwa zake ndi dzenje pachimake.Ngati pali zolakwika kapena madera akuluakulu opanda kanthu, filimuyo yomwe ikuyang'anizana ndi plywood idzakumana ndi kuphulika, kusweka, ndi zochitika zina.

Pomaliza, titha kuwiritsanso mawonekedwe omangira ocheka ngati mizere yamatabwa m'madzi kuti tiwone ngati mphamvu yake yomangirira ndiyoyenera.Ikani chitsanzocho m'madzi otentha kwa maola awiri kuti muyese mphamvu yolumikizira filimuyo ikuyang'anizana ndi plywood.Izi ndikufanizira ngati template yomangayo idasweka pambuyo pakugwiritsa ntchito 2-3.Ngati pali zizindikiro zosweka, zimasonyeza kuti khalidwe lake silopambana ndipo zotsatira zake zamadzi ndizochepa.Kupanga filimu yoyang'anizana ndi plywood kunganenedwe kukhala maziko a ntchito zathu zomanga, ndipo mtundu wa filimu yoyang'anizana ndi plywood umagwirizana kwambiri ndi mphamvu ya ntchito zathu zomanga.
