Wood khola: icho chiri ndi kumene ntchito?

Okhazikika mtengo - ndi mankhwala analandira patapita nthawi yaitali osati njira zophweka processing nkhuni zakuthupi. Olimba amaona kuti m'malo luso kuposa akhale mmisiri kuyambira mbuye ali kuika zinamuchitikira onse, m'maganizo ndi luso kutulutsa chitsanzo zofunika.

Olimba nkhuni ndi chitsanzo zodabwitsa wokongola anapanga chifukwa cha ntchito nthawi ndi yolemetsa. Nkhani chifukwa akutumikira monga maziko a amangomvera zochititsa chidwi ndi zachilendo mipeni zodzikongoletsera akazi osiyanasiyana ndi alendo. mankhwala zikhoza kugulidwa ndi kulipira khobidi wokongola, kapena kuchita izo nokha.

N'chifukwa kukhazikika nkhuni

mtengo uliwonse, amphamvu ndi womveka mitundu ngakhale ngati monga thundu kapena phulusa, posapita nthawi, timakhala zinthu zosiyanasiyana zowononga. Iwo olema, olumala, kuyamwa chinyontho kapena, Tikawonetsetsa rassyhaetsya. Kuti tidzakhale ndi moyo wa zinthu matabwa, iwo ataphimbidwa ndi kukupatsidwa mimba zosiyanasiyana, utoto, emulsions ndi vanishi. zinthu izi musunge chuma, kuteteza avale msanga ndi kupanga pamwamba pake ndi wandiweyani wosanjikiza zozitetezera.

Ubwino ankachitira zinthu

Wood khola sikutanthauza ntchito njira iliyonse, chifukwa zinapatsira ndi njira yapadera. olimba luso kumafuna nadzaza pores ndipo cavities usawonongeke zopangira amene pambuyo akuchiritsa otembenuka mtengo nkhani yokhala ndi katundu zatsopano:

• mkulu osalimba, kuuma ndi mphamvu;
• kukana monyanyira kutentha ndi chinyezi kusintha zizindikiro chilengedwe;
• chitetezo chokwanira wathunthu UV cheza;
• mphamvu kwa nthawi yochepa kukhala mu lawi lotseguka popanda imfa ya makhalidwe quality, kusintha maonekedwe ndi mapindikidwe;
• impermeability kwa mafuta;
• kugonjetsedwa ndi mankhwala ndiponso.

Kuwonjezera onse pamwamba, okhazikika kuthabwa ndi wokongola kwambiri. Transparent kapena akuda impregnating anatsindika chitsanzo masoka ulusi matabwa, kupanga dongosolo ndi zina zidzasintha ndi zokongola. Kuchitira zinthu chifukwa zimakhala pamanja ndi njira makina.

Njira ofunika (chosunga) matabwa

Mu zikuluzikulu khola nkhuni (chithunzi machenjerero ake mukhoza kuona m'nkhani) amapangidwa pa apadera mafakitale kupala matabwa. Ogwira ntchito m'madipatimenti ameneŵa ntchito njira mankhwala ndi impregnation quality, kuwonjezera, iwo ndi mwayi bungwe ndi kugwilizana ndi luso lamanja.

Mtumiki amene ntchito njira anafotokoza ndi:

• mafuta (zambiri linseed);
• lacquer;
• kujambula;
• polima kapena utomoni impregnation.

Chifukwa cha ntchito ya akatswiri si wotsika mtengo koma amene mukufuna kupeza mankhwala a nkhaniyi zachilendo, osadandaula. Pali njira zingapo ntchito kunyumba amisiri kupanga mankhwala ofanana ndi fakitale.

Okhazikika nkhuni ndi manja anu chingapangidwe kuchokera ku zipangizo ndi chitsanzo wokongola ulusi ndi kapangidwe adzaoneni. Njira mu mtima kapu yolimba:

• birch;
• mapulo;
• Elm;
• mgoza.

Kapoma otchedwa kumanga-pa nthambi, thunthu kapena pafupi mizu ya mitengo, ulusi wake zapiringizana ndi masamba matalala. Burls nkhuni ndi zinthu mwachilungamo mtengo chifukwa cha kachulukidwe ake, m'chipani ndi kukongola kwa kapangidwe.

Okhazikika matabwa mu nyumba zopangidwa mogwirizana ndi kutentha anakhumba, zingalowe m'malo ndi ena kuthamanga mlingo.

Kodi njira ndi impregnated nkhuni

Pambuyo kusankha kwa feedstock abwino, mbuye atuluka mwachindunji impregnation sitepe. Malinga ndi kukula ndi mtundu wa choyambira, komanso kuganizira mphamvu zake ndi zokonda, izo amasankha imodzi mwa njira zingapo:

1. Woonda preform akhoza impregnated ndi kutentha m'malo otsika (ozizira impregnation).
2. Hot impregnation. Amakhala mu akuwukha kapena kuphika workpiece mu njira yapadera. M'chigawo otentha wa kugwirizana awo umakhala madzi, amene amathandiza mankhwala kudutsa mu ulusi.
3. Kugwiritsa chipinda zingalowe (ikukoka mpweya ku cavities matabwa). Zimenezi zikhale zosavuta kudzaza capillaries litasamuka ndi pores wa impregnating zikuchokera.
4. Chirengedwe cha kuthamanga owonjezera m'chipinda, limene kale anaika chidebe cha njira ndi matabwa. Dongosololi amakwiya mpweya kubwereketsa ku CHIKWANGWANI ndi chimakankhira wa anamasulidwa danga impregnation.

Wood okhazikika: akamaliza processing, polymerization

Polymerized preform ndi kuyanika. Mitundu ina ya nyimbo mwina kudziletsa oipa, pamene ena pansi tima kuyanika pa kutentha. nkhuni Polymerized afika kulemera owonjezera, mtundu watsopano ndi katundu.

The chifukwa cha kuphedwa olondola a imeneyi amakhala nkhuni khola. Ndi manja awo (chithunzi cha chitsanzo yomalizidwa aikidwa m'nkhani), nkhuni mankhwala, monga ulamuliro, anthu ambuye, amene pambuyo pake akufuna kugulitsa zinthu chifukwa.

Nthawi zambiri amisiri izi zikugwira kupanga ndi azidzipereka malonda a matabwa, amene ali wangwiro monga mphatso ndi alendo. The zambiri ntchito nkhuni mipeni khola (amangomvera), zoyatsira thupi ndi zolembera, mabokosi, komanso zosiyanasiyana zodzikongoletsera (mikanda, zibangili, medallions).

Kodi ziziyenda nkhuni zikuchokera "Anakrol 90"

impregnation Izi mulingo woyenera ntchito kunyumba, chifukwa n'zosavuta kwambiri kupeza, ndi fluidity ya kapangidwe limachititsa kudutsa mu pores onse workpiece lapansi. Ena ojambula zithunzi amakonda kugwiritsa ntchito ndi epoxy utomoni, koma ndi zambiri viscous ndi m'malo capricious njira. Chifukwa ntchito yake ndi moyo kumafuna zambiri, kuleza mtima ndi kulemekeza luso. Komanso utomoni sangathe kugwiritsidwa ntchito processing wa softwoods.

Kuti akachite kusamala nkhuni "Anakrolom 90", akonze zipangizo ndi zida:

• matabwa;
• impregnation;
• dongosolo zingalowe (a kusonkhanitsa ake ayenera ikuluikulu makontena a pulasitiki cranes, pulasitiki chubu);
• wosatsogoleredwa mpope;
• ndi kompresa;
• chipangizo liwulo mphamvu kuthamanga (n'zotsimikizira);
• uvuni kapena aerogrill.

Small workpiece (za 3 cm wandiweyani) impregnated kwambiri msanga ndiponso mosavuta. Ziziyenda mtengo pamwamba ayenera kukhala wouma.

Kodi nkhuni kuteteza

Tikumbukenso kuti kugwiritsa ntchito njira bwino anatsindika okongola a mtengo ndi ntchito inki kapena mitundu akuda a impregnation limakupatsani kulenga wapadera ndi wapadera chitsanzo.

The ndondomeko ya ntchito:

1. mtengo anaikidwa mu chidebe cha njira, kusamalira kuti madzimadzi kwathunthu chimakwirira workpiece.
2. Anasamutsidwa mpaka mpaka mpweya thovu kutha.
3. Perekani impregnation kuima pafupi maminiti makumi awiri, kenako chotengera kulenga overpressure (2-4 ATM). njirayi amafuna kugwiritsa ntchito kompresa ndi mpope.
4. Pambuyo yopuma theka la ora, kubwereza ndondomeko.

Akamaliza ofunika nkhuni

Inu ndikufuna kubwereza ndondomeko anafotokoza kangapo konse kuti mumvetse mfundo kwenikweni apamwamba. chiwerengero cha m'zinthu zimadalira zinthu zambiri (kukula preform kalasi mtengo, mtengo khalidwe). Master akhoza kudziwa wokonzeka okhazikika ndi workpiece, izo limalephera kapena amayandama mu njira. Impregnation wopambana mtengo wagwa pansi.

preform Komanso anakoka ndi zouma mu ng'anjo kapena mu ng'anjo pa kutentha madigiri 100. Adzaweruza bwanji mtengo adzauma, n'zotheka, kuganizira mawanga yonyowa pamwamba pake. Pamene iwo musakhale, mukhoza kusiya kuyanika.

Ankachitira nkhuni amakhala lolemererapo kwambiri, uyenera kuthandiza kupukuta ake ndi kutchukitsa mankhwala.

Kudziwa mmene kupanga nkhuni khola, icho chiri ndi zolinga ntchito, inu mukhoza kuchita izo nokha Mlengi.

Zimenezi ndi ndimasewera kwambiri, tikhoza kusangalatsa ndi kudabwa zotsatira zawo mmisiri mtima. Sayenera kuopa kulephera, chifukwa, monga iwo amati, "choncho mbuye ndi mantha!"
