Aluminiyamu matabwa mbiri kwa kutsetsereka chitseko
Tsatanetsatane mankhwala
Mbiri ya matabwa ya aluminiyumu yolowera pakhomo, ndiyotchuka kwa ogwiritsa ntchito apakhomo. Timapereka zojambula zambiri zomwe mungasankhe. Anthu amagwiritsa ntchito matabwa a aluminiyamu m'malo mwa matabwa oyera.
Mitengo yotengera mbewu zamatabwa, nthawi zambiri amasankha mtengo wapamwamba komanso wotsika wa hydroxyl wamitundu iwiri ya poliyesitala. Ngati mtengo wa hydroxyl awiriwo ndi wochepa kwambiri, kusiyana kwa nthawi ya gelling, kulekana kwa zokutira ndi kutengerapo pepala sikophweka. Kupyolera muzoyesera zambiri, tinatsimikiza 75 mgKOH/g monga mtengo wa hydroxyl polyester resin hydroxyl,> 75mgKOH/g high hydroxyl value, hydroxyl value <75mgKOH/g ndi yotsika, filimuyi ndi yosavuta kupeza ndi kusamutsa kupatukana pepala ili limagwiritsa ntchito poliyesitala. resin mitundu iwiri ya hydroxyl mtengo.
Monga kusindikiza kwa mbewu kutengera dzimbiri, kukana kukana, kukana kukalamba, kuvala ndi kung'ambika, kuteteza moto, kugwiritsa ntchito panja, zaka 15 popanda kusintha mtundu ndi katundu wina, pafupifupi zinthu zonse zimapangidwa motere. Mwachitsanzo, tsegulani chipolopolo cha foni yam'manja, mkati mwa nduna mutha kuwona zokhala ndi zilembo zama bar. Zolemba zambiri zimatha kupirira mayeso a nthawi, mapindikidwe a nthawi yayitali, samazirala, osati chifukwa cha zosungunulira zidzavala, osati chifukwa cha kutentha kwakukulu pa mapindikidwe ndi kusinthika, ndikofunikira kutengera mtundu wapadera. zakuthupi kusindikiza sing'anga ndi kutengerapo zinthu tirigu kuonetsetsa kuti makhalidwe amenewa, ambiri inki-ndege, laser kusindikiza luso sangathe kukwaniritsa.
