Gulu la mabotolo agalasi (I)

1.Kugawa ndi njira yopangira: kuwomba kopanga; makina kuwomba ndi extrusion akamaumba.

2. Gulu mwa kupanga: galasi la sodium; galasi lotsogolera ndi galasi la borosilicate.
3. Gulu ndi kukula kwa pakamwa pa botolo.
① Botolo lapakamwa laling'ono. Ndi botolo lagalasi lokhala ndi mainchesi amkati osakwana 20mm, omwe amagwiritsidwa ntchito kwambiri kuyika zinthu zamadzimadzi, monga soda, zakumwa zoledzeretsa, ndi zina zambiri.
② Botolo la kukamwa kwakukulu. Mabotolo agalasi okhala ndi mainchesi amkati a 20-30mm, okhala ndi mawonekedwe okhuthala komanso aafupi, monga mabotolo amkaka.
③ Botolo la kukamwa kwakukulu. Monga mabotolo am'chitini, mabotolo a uchi, mabotolo a pickle, mabotolo a maswiti, ndi zina zotero, zokhala ndi mkati mwake kuposa 30mm, khosi lalifupi ndi mapewa, mapewa ophwanyika, ndipo makamaka zitini kapena makapu. Chifukwa cha pakamwa pa botolo lalikulu, kutsitsa ndi kutsitsa ndikosavuta, ndipo kumagwiritsidwa ntchito kwambiri kuyika zakudya zam'chitini ndi zinthu zowoneka bwino.
4. Gulu ndi geometry ya botolo
① Botolo lozungulira. Gawo lalikulu la botolo la botolo ndilozungulira, lomwe ndilo mtundu wa botolo womwe umagwiritsidwa ntchito kwambiri ndi mphamvu zambiri.
②Botolo la square. Gawo la mtanda la botolo ndi lalikulu. Botolo lamtunduwu ndi lofooka kuposa mabotolo ozungulira komanso ovuta kupanga, choncho sagwiritsidwa ntchito mochepa.
③Botolo lopindika. Ngakhale kuti mtandawo ndi wozungulira, umakhala wokhota kumapeto. Pali mitundu iwiri: concave ndi convex, monga vase mtundu ndi gourd. Maonekedwe ake ndi achilendo komanso otchuka kwambiri ndi ogwiritsa ntchito.
④Botolo la oval. Gawo la mtanda ndi oval. Ngakhale kuti mphamvuyo ndi yaying'ono, mawonekedwe ake ndi apadera ndipo ogwiritsa ntchito amakondanso.
