Izidingo eziyisithupha ezinkulu zokuthenga isikhunta sepulasitiki azikwazi ukushaywa indiva

1. Ukumelana nokugqwala okuphezulu Ama-resin amaningi nezithasiselo zinomthelela olonakalisayo ebusweni bomgodi.Lokhu kugqwala kubangela insimbi engaphezulu komgodi ukuba igqwale futhi ixetshulwe, isimo esingaphezulu siyawohloka, futhi izinga lezingxenye zepulasitiki liwohloke.Ngakho-ke, kusetshenziswa insimbi engagqwali, noma ingaphezulu le-cavity limbozwe nge-chromium noma i-nickel ye-cymbal.

2.Ukumelana kahle nokuhuzuka.Ukucwebezela nokunemba kobuso bezingxenye zepulasitiki zepulasitiki kuhlobene ngokuqondile nokumelana nokuhuzuka kobuso besikhunta sepulasitiki, ikakhulukazi lapho i-glass fibre, izigcwalisi ze-inorganic kanye nezingulube ezithile zengezwa kwamanye amapulasitiki.Kanye nokuncibilika kwepulasitiki, kugeleza ngesivinini esikhulu kumgijimi kanye nesikhunta, futhi kunokungqubuzana okukhulu ebusweni bomgodi.Uma impahla ingagugi, izoguga ngokushesha, okuzolimaza ikhwalithi yengxenye yepulasitiki.

3.Ukuzinza okuhle kwe-dimensional.Ngesikhathi sokubunjwa kwepulasitiki, izinga lokushisa lesikhunta sepulasitiki kufanele lifinyelele ngaphezu kwama-300 ° C.Ngenxa yalesi sizathu, kungcono ukukhetha insimbi yamathuluzi (insimbi ephethwe ukushisa) eye yafudumala kahle.Uma kungenjalo, i-microstructure yezinto izoshintsha, okuzokwenza ukuthi ubukhulu besikhunta sepulasitiki sishintshe.

4.Izingxenye zokubunjwa okulula ukuzisebenzisa ngokuvamile zenziwe ngezinto zensimbi, futhi ezinye izimo zesakhiwo zisayinkimbinkimbi kakhulu.Ukuze unciphise umjikelezo wokukhiqiza futhi uthuthukise ukusebenza kahle, izinto zokubumba ziyadingeka ukuze kube lula ukucubungula zibe yisimo nokunemba okudingekayo ngemidwebo.

5.Ukusebenza okuhle kokupholisha.Izingxenye zepulasitiki zepulasitiki ngokuvamile zidinga isicwebezelisi esihle nesimo esingaphezulu.Ngakho-ke, ukuqina kwe-cavity surface kuyadingeka ukuba kube kuncane kakhulu.Ngale ndlela, ubuso bomgodi kufanele bucutshungulwe phezulu, njengokupholisha, ukugaya, njll. Ngakho-ke, insimbi ekhethiwe akufanele iqukathe ukungcola okunzima kanye nama-pores.

I-6.I-Less ethintekayo ekwelapheni ukushisa Ukuze kuthuthukiswe ubulukhuni nokumelana nokugqoka, isikhunta sepulasitiki ngokuvamile siphathwa ngokushisa, kodwa lokhu kwelashwa kufanele kwenze usayizi ushintshe ube mncane.Ngakho-ke, insimbi eqinile ngaphambili engasikwa isetshenziswa.
