Umzi-mveliso webhetri ye-lead-asidi kwilizwe lam unembali engaphezu kwekhulu leminyaka. Ngenxa yeempawu zemathiriyeli exabiso liphantsi, itekhnoloji elula, itekhnoloji evuthiweyo, ukuzikhupha okuphantsi, kunye neemfuno zokungakhathali, iya kuhlala ilawula intengiso kumashumi ambalwa eminyaka azayo.
Ngokunyuka kweemfuno zomgangatho wensimbi ephosiweyo, ukusetyenziswa kwe-aluminium ye-deoxidation ye-castings ephezulu yezinga eliphezulu ayikwazi ukuhlangabezana neemfuno. Ngoko ke, ukusetyenziswa kwe-aluminium kunye ne-calcium composite deoxidation ifumene ingqwalasela enkulu.
Iimpawu eziphambili zeZinc Alloy:
1. Umlinganiselo omkhulu.
2. Ukusebenza kakuhle kokuphosa, kunokufa-indawo echanekileyo kunye neemilo ezintsonkothileyo kunye neendonga ezibhityileyo, ezinendawo yokuphosa egudileyo.
Ipeyinti yokumakisha yendlela ikwabizwa ngokuba yipeyinti yokumakisha yendlela, Ikwabizwa ngokuba yipeyinti yepeyinti echasene nokutyibilika. Ulwahlulo lwayo oluneenkcukacha ngolu hlobo lulandelayo:
I-resin ekhethekileyo yepeyinti yokuphawula indlela enyibilikayo eshushu yi-M2000A ephuhliswe yinkampani yethu emva kweminyaka yophando. Yenziwe nge-rosin, i-polymer ephezulu ye-molecular, i-unsaturated dibasic acid, kunye ne-polyol emva kwe-polycondensation kunye ne-esterification, yongeza i-heat stabilizer, ukukhanya Kwenziwe emva kokuqiniswa. Xa kuthelekiswa ne-rosin yendabuko ehlaziyiweyo yendlela yokuphawula ipeyinti yentlaka,
Ipeyinti yophawu lwendlela yipeyinti efakwa endleleni ukuphawula iimpawu zendlela. Luphawu lokhuseleko kunye "nolwimi" kuhola wendlela. Ngoko ke zeziphi iingxaki eziqhelekileyo ekwakhiweni kwepeyinti yokumakisha indlela eshushu enyibilikayo? Ziziphi izicombululo?
