Ndi mitundu yanji ya zinthu za pulasitiki nkhungu?

Pulasitiki nkhungu zakuthupi ndizomwe zimagwiritsidwa ntchito popanga nkhungu zapulasitiki, zomwe zimakhudza mwachindunji kupanga bwino komanso mtundu wazinthu zapulasitiki.Malinga ndi magawo osiyanasiyana ogwiritsira ntchito, zofunikira komanso mtengo wake, zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi nkhungu zapulasitiki zimaphatikizapo mitundu iyi:

1. Mpira wa silicone
Rabara ya silicone ndi nkhungu yapamwamba kwambiri, yomwe imadziwika ndi kukana kutentha kwambiri, osati kukalamba, ndipo imakhala yabwino komanso yosinthasintha.Choncho, mphira wa silikoni ndi woyenera kuumba jekeseni zomwe zimafunika kukonzedwa pafupipafupi pa kutentha kwakukulu.

2, Polyimide (PAI)
Polyimide ndi zinthu zapamwamba kwambiri za polima, zomwe zimadziwika ndi kukhazikika kwamafuta, mankhwala ndi makina, komanso zimakhala ndi kukana kwabwino kwambiri, kukana kukhudzidwa.Izi ndizoyenera kuumba zomwe zimafunikira kutulutsa mwatsatanetsatane komanso moyo wautali.

3. Polyamide (PA)
Polyamide ndi zinthu zapamwamba za polima, zomwe zimadziwika ndi kupepuka komanso kusinthasintha, komanso zimakhala ndi mphamvu zambiri komanso kuuma.Chifukwa cha zinthu zake zoyenerera, nkhaniyi ndi yoyenera kupanga nkhungu pazinthu zosiyanasiyana zapulasitiki.

4, Thermoplastic polyamide (TPI)
Thermoplastic polyamide ndi mtundu wa kutentha kwambiri komanso ntchito yapamwamba ya nkhungu ya pulasitiki, yomwe imadziwika ndi kukana kutentha kwambiri, kudana ndi kuipitsa, kukhazikika kwamakina ndi mankhwala.Zinthuzi zimagwiritsidwa ntchito kwambiri popanga madera monga mafakitale agalimoto ndi ndege.

5. Chitsulo
Chitsulo ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi nkhungu.Amagwiritsidwa ntchito kwambiri popanga nkhungu ya jakisoni chifukwa cha kuuma kwake kwakukulu, kukana kuvala bwino komanso kulondola kwambiri.Mitundu yosiyanasiyana yazitsulo ndi yoyenera pazinthu zosiyanasiyana zopangira jekeseni, monga P20 zitsulo ndizoyenera kupanga zinthu zapulasitiki zolimba.

Pamwambapa angapo ndi mitundu wamba pulasitikinkhunguzipangizo, ndipo mtundu uliwonse uli ndi makhalidwe ake ndi ubwino m'madera osiyanasiyana ogwiritsira ntchito ndi zofunikira.Malinga ndi zosowa zenizeni, sankhani chinthu choyenera cha nkhungu, kuti mupange zinthu zapulasitiki zokhutiritsa.
