Ngati mukufuna kupanga zosungirako zokhazokha ndi kupanga pa slabs , muyenera kugula nkhungu zapamwamba zomwe zidzakutsatirani ndikukulolani kupeza miyala yabwino.
Kodi mawonekedwe pansi pa miyalayi ndi yotani?
Choyamba, mawonekedwe opangira zosiyana amasiyana. Masiku ano zambiri za nkhungu zimapangidwa ndi pulasitiki ya PVC, pulasitiki ya ABS ndi polystyrene. Sikoyenera kutenga nkhungu za mphira kuti zisakanike, chifukwa miyala ndi miyala yopangidwa kuchokera pansi siikwanira bwino.
Sitikulimbikitsanso kutenga nkhungu kuchokera ku secondary secondary granular polystyrene, chifukwa pakuchita sizimatsimikiziranso khalidwe lolonjezedwa la zotsatira zake. Ndizovuta, kupanga zojambulazo, chifukwa zojambula kapena zojambulazo sizingatheke. Kuonjezera apo, mafomuwo amakhala osasinthika.
Zokongoletsera zopangira filimu PVC plastiki zakhala zabwino kwambiri. Amatumikira nthawi yaitali kuposa ena, ali oyenerera teknoloji iliyonse, samasowa kutsuka pambuyo pa ntchito. Kuwombera mmenemo kuli okonzeka pafupifupi maola 12. Kutalika kwa makoma a mawonekedwe awa kumachokera ku 0,8 mm.
Mitundu ya granulated polymer polystyrene imapanga pansi ndi kuchitapo kanthu kwa kuthamanga kwakukulu. Nthawi zonse amakhala ndi geometry yoonekera komanso khalidwe lapamwamba. Ndi iwo, mukhoza kupanga mpaka 500 castings. Mwala umene umapangidwirawo umakhala wokongola kwambiri. Zokongoletsazi ndizofunikira pa tepi iliyonse yopanga tepi.
Gulu lina la mafomu omwe amalowetsa ndi nkhungu. Zimapangidwa ndi zipangizo zolimba, nthawi zambiri - zitsulo. Njira yogwirira ntchito ndi izi: nkhungu zodzala ndi konkire zimayikidwa pa tebulo logwedezeka ndipo, kuwonjezera pa kugwedeza, phokoso logwedezeka limagwiritsa ntchito kusakaniza, patapita kanthawi, matrix ndi phokoso likukwera, ndipo matalala omalizira amakhalabe patebulo.
