Khola mtengo: Njira yonama ndi mbali

Pakuti ambiri funso n'lakuti, chomwe chimatanthauza "mtengowo ukhale wolimba." Izo zinthu mwapadera mankhwala ndipo analandira zina makhalidwe kukongoletsa ndi durability, chitsanzo zachilengedwe amakhalabe sichinasinthe.

mafotokozedwe

mtundu wa chithandizocho komanso nthawi zambiri amatchedwa motetezera, ndipo m'pake kutero, chifukwa ntchito yaikulu ndi kuika kusunga ndi kuwongolera nkhuni. Kupeza chifukwa zinthu zimenezi pogwiritsa ntchito chuma chapadera chomwe chimadzaza pores ndi ikamauma. Ambiri anapeza resins, polima ndi utoto formulations, mafuta zosiyanasiyana.

Khola mtengo kwathunthu zimatenga a mitundu kapangidwe zimatengera pa kamvekedwe latsopano osati padziko komanso mu dongosolo la. Pali zinthu zosiyanasiyana kwa kudetsa kwa zachilengedwe mitundu yowala.

Features

Zotsatira yoyenera zimafuna kukonzekera mokwanira ndi kutsatira mosamala malamulo onse. Paokha kuti asiye kulenga mlingo Napempha kwa kuthamanga, zingalowe ndi zina kutentha boma koma kuteteza kumakhala kovuta popanda zinthu zimenezi.

Choyamba, muyenera kunyamula workpiece bwino. Nthawi zambiri, ali ngati zinthu ndi modulations okongola ndi dongosolo, n'kutheka hardwoods osiyana: mgoza, Elm, mapulo ndi birch.

Khola mtengo ali katundu zotsatirazi:

• kuuma;
• kachulukidwe;
• kukana mafuta zosiyanasiyana ndi mankhwala ndiponso;
• kwambiri kukongoletsa makhalidwe;
• Khola mtengo zimasunga katundu ngakhale pamene usavutike lawi lotseguka.

impregnation

Sitepe akhoza kuchitidwa ndi njira zosiyanasiyana:

• Olimba a kuthamanga. Chifukwa chaichi, ndi chidebe anasankha ladzala ndi zikuchokera imene preform kumizidwa. Ndiye chidebe aikidwa mu chipinda apadera ndi kuthamanga chinawonjezeka ndi kwaiye. zimakhudza mfundo ndi mpweya n'kuthamangitsidwa workpiece, ndi malo wopanda ladzala ndi matope.
• Zingalowe ndondomeko. Mabukuwa aikidwa mu chipinda kumene mpweya kenako amawapopa kunja, ndipo monga lotulukira ku workpiece lapansi. Choncho njira mosavuta Amaipitsanso capillaries ndi pores kanthu.
• Hot impregnation. Nkhuni ndi yophika kapena ankawaviika formulations wapadera. Yodziwika pogwiritsa ntchito liquefaction ndi Kutentha, potero kwambiri kuwonjezeka flowability nadzaza khalidwe.
• Cold impregnation ndi mulingo woyenera wina kwa workpieces woonda.

polymerization

Zimenezi itha processing ndi amapangidwa ndi kuumitsa mankhwala pa kutentha chofunika. Okhazikika nkhuni amangomvera kupeza makhalidwe atsopano, kupereka kufanana ndi zipangizo polymeric, monga chingasinthe mtundu ndi kulemera. Choncho khalidwe la ulusi ndinu yemweyo, iwo Komanso kukonza njira ntchito processing, potero kupanga wolemekezeka komanso yokongola maonekedwe a preform lonse. Dziwani kuti ena mwa zipangizo ntchito pa siteji iyi, osiyana katundu samozatverdevaniya.

Kodi ziziyenda mpeni chogwirira mtengo

Nkhani kukonzedwa ndi yabwino kwa chilengedwe cha mankhwala osiyanasiyana ndi handicrafts. Iwo zambiri ntchito kupanga amangomvera yekha kwa mipeni.

Limodzi nyimbo otchuka kwa usawonongeke "Anakrol 90", kutsanulira kufika umene uli mwa madigiri 90. Kwa ntchito amafuna dongosolo zingalowe, izo zikhoza kupangidwa mwa zigawo izi: kuthamanga n'zotsimikizira, kompresa mpweya, mpope zingalowe, chiwerengero cha timachubu, makontena a pulasitiki wa chachikulu. Kenako, okhazikika nkhuni ndi zouma mu uvuni wapadera, sanamwe akhoza kugwiritsa ntchito Aerogrill kapena uvuni.

Makulidwe mayi ntchito sayenera upambana 3-4 cm, m'pofunika kuti apamwamba impregnation wa preform lapansi.

The mbale matabwa aikidwa mu chidebe ndi yankho, pamene izo ziyenera kwathunthu yokutidwa anakrolom. zingalowe The analengedwa mpaka ndiye, mpaka palibe mpweya mutsanulira kunja.

Komanso, kuthamanga analengedwa, chisanadze chiphunzitso ayenera kuyima kwa theka la ola. kuthamanga mlingo ayenera kuyesetsa kuti 2-4 ATM, pamafunika kugwiritsa ntchito mpope ndi kompresa lapansi. ndondomeko ayenera mobwerezabwereza pambuyo Mphindi 40. Zochita akutsatiridwa bola ngati mankhwala si kumira m'madzi. Pankhaniyi, palibe chipeneko Mkhalidwe impregnated preform.

Ndiye kuti mtengowo ukhale wolimba ndi manja ake Ndi bwino zouma ndi kutentha pafupifupi 100 madigiri. Pambuyo ayenera kwina yaiwisi mawanga. Zinthu zimenezi amapereka mkulu osalimba zakuthupi ndi bwino kupukuta ntchito. Nonstandard dongosolo kulocha akhoza zopezera powonjezera inki zosiyanasiyana zikuchokera. Komanso lero, angapezeke pa malonda njira okonzeka zopangidwa ndi zosiyanasiyana mithunzi.

Kugwiritsa epoxy utomoni

Njira imeneyi ndi yofanana ndi kuteteza ndi anakrola, kusiyana waukulu lagona m'malo ake ndi epoxy utomoni wothira mowa. Yotsirizira ntchito kuwongolera impregnation. Kugwira ntchito ndi utomoni imafunanso kuleza mtima, kotero malinga ngati polymerized kuti boma akufuna. Pali zambiri njira zosiyanasiyana zochokera utomoni epoxy. Khola kwa nkhuni mitengo chifukwa cha ntchito ya kapangidwe amenewa ndi digiri yapamwamba ya fluidity, yodziwika ndi makhalidwe abwino.
