Zipewa zodzitchinjiriza nthawi zambiri zimayikidwa mu nsapato zomalizidwa zomwe zimatha kupereka kukana komanso kukana kwambiri.Zipewa zakumapazi zomwe poyamba zimapangidwa nthawi zambiri zimakhala zipewa zachitsulo, komanso palinso zipewa za aluminiyamu.Pokhala ndi zipewa zopepuka komanso zosavuta zapaphazi, zipewa zapulasitiki zotetezedwa komanso zipewa zopanga zala zopanda zitsulo zalowa pang'onopang'ono pamsika m'zaka zaposachedwa.
Monga ubwino wa chitetezo chazitsulo zapulasitiki zotetezera zimadziwika ndi mafakitale ambiri, zakhala zikugwiritsidwa ntchito ku mitundu yonse ya zipewa zapanja zakunja.Kapangidwe kazovala zam'manja ndizochepa kwambiri, ndipo nsapato izi ndizoyenera kuvala tsiku lililonse.Komabe, ngati atavala m'malo okhala ndi zinthu zosakhazikika kwambiri m'nkhalango, amakhala osavuta kupyozedwa ndi miyala yakuthwa paphiri ndikuvulaza zala zala, komanso sizimathandiza kubisala ndikuchepetsa mphamvu yakugundana pambuyo pokhudza. zinthu zovuta.Kuonjezera apo, nsapato zambiri zakunja sizikhala ndi zigawo zowonongeka, zomwe zimapangitsa anthu kutopa komanso kupweteka mosavuta.
Main makhalidwe chitetezo pulasitiki chala kapu
1. Imakhala ndi mphamvu zambiri komanso zotanuka, mphamvu yamphamvu kwambiri komanso kutentha kwamitundu yosiyanasiyana.
2. Zowoneka bwino kwambiri komanso zaulere.
3. Low kupanga shrinkage ndi wabwino dimensional bata.
4. Kukana kutopa kwabwino.
5. Kukana kwanyengo kwabwino.
6. Makhalidwe abwino kwambiri amagetsi.
7. Zopanda fungo ndi zosakoma, zopanda vuto kwa thupi la munthu, mogwirizana ndi thanzi ndi chitetezo.
A. Makina amakina: mphamvu yayikulu, kukana kutopa, kukhazikika kwapang'onopang'ono, kukwawa pang'ono, ndikusintha pang'ono pansi pa kutentha kwakukulu.
B. Kukana kukalamba kwa kutentha: Kuwonjezeka kwa kutentha kwa UL kumafika pa 120-140 ℃, ndipo kukana kukalamba kwakunja kwanthawi yayitali kulinso kwabwino.
C. Kukana zosungunulira: palibe kupsinjika maganizo.
D. Kukhazikika kwa madzi: N'zosavuta kuwola pamene ili m'madzi otentha kwambiri, ndipo iyenera kugwiritsidwa ntchito mosamala pansi pa kutentha kwakukulu ndi chinyezi.
E. Kuchita kwamagetsi.
F: Kupanga njira-kuthekera: jekeseni wamba wa zida kapena extrusion.
