Sintered Materials Dzinoramba Sei Corrosion Pasinei nePorosity Yadzo?
*Zvisinei nehunhu hwadzo husina huturu, zvinhu zvakanyungudutswa zvinoramba corrosion nekuda kwe:
1.Kusarudzwa kwezvinhu:
Corrosion-resistant alloys, sesimbi isina tsvina, inowanzoshandiswa mukupisa.
2.Porosity Control:
The interconnected pores inodzikamisa corrosive kupinda.
3.Protective Treatments:

Saka Muchinyorwa chino, isu tichaongorora kuti zvinhu izvi zvinobvumira sei sintered zvinhu kuchengetedza zvese zvakakwirira nzvimbo uye kusagadzikana kwekuora.
Chii Chinonzi Sintered Materials?
Tsanangudzo:
Sintered zvinhu zvinogadzirwa nekudziisa simbi yehupfu kana ceramic zvinhu kusvika pazasi penzvimbo yazvinonyungudika, zvichiita kuti zvimedu zvibatane pamwechete kuita chimiro chakasimba. Iyi nzira inogadzira chinhu chine yakasarudzika musanganiswa wesimba, porosity, uye kushanda.
Iyo Sintering process:
Iyo sintering process inosanganisira kubatanidza simbi kana ceramic poda kuita mold uye wozoisa kupisa. Tembiricha yakakwira zvekusanganisa zvimedu, asi hazvina kukwana kunyungudusa zvizere. Nekuda kweizvozvo, zvimedu zvinosungirirana panzvimbo dzazvo dzekubatana, zvichigadzira chinhu chakasimba asi chine porous.
Zvakajairwa Zvishandiso zveSintered Materials:
*Kusefa: Sintered zvinhu, kunyanya sintered simbi mafirita, anoshandiswa muakasiyana kusefa maapplication nekuda kwenzvimbo yavo yepamusoro uye kugona kutora zvimedu zvakanaka.
*Catalysis: Mune maitiro ekugadzirisa, sintered zvinhu zvinoshanda sezvitsigiro zvezvimedu zvinokonzeresa, zvichipa nzvimbo yakakwirira uye kuramba kukora uye kupfeka.
*Aeration: Sintered zvinhu zvinoshandiswawo muaeration masisitimu, senge carbonation matombo mukubika, nekuda kwekugona kwavo kuparadzira magasi nemazvo kuburikidza nechimiro chavo cheporous.
Sintered zvinhu zvinokosheswa mumaindasitiri nekuda kwekuita zvakasiyana-siyana uye kugona kusanganisa zvivakwa zvakaita sesimba rakanyanya, kupisa kwekupisa, uye kushomeka kwemarara.
Kunzwisisa Iyo Yepamusoro Surface Nzvimbo yeSintered Materials
Nzvimbo yepamusoro yepamusoroinoreva nzvimbo yose inowanikwa pamusoro pechinhu, maererano nehuwandu hwayo. Muchirevo chezvinyorwa zvakasvibiswa, zvinoreva kuti zvinhu zvacho zvine huwandu hwakakosha hwenzvimbo yakafumurwa mukati memu compact fomu, nekuda kweiyo porous chimiro. Izvi zvinokonzerwa netiweki yakabatana yemapores madiki akagadzirwa panguva yekuita sintering.
Tsanangudzo yePorosity uye Kukosha Kwayo muIndasitiri Zvishandiso
Porositychiyero chenzvimbo dzisina chinhu (pores) mukati mechinhu. Kune zvinhu zvakasvibiswa, porosity chinhu chakakosha, sezvo ichibvumira kuti zvinhu zvive zvisina kureruka, zvinopinda, uye zvinoshanda mumashandisirwo apo kuyerera kwemvura kana gasi kunobatanidzwa. Porosity mune sintered zvinhu zvinowanzoitika kubva pa30% kusvika 70%, zvichienderana nezvinodiwa.
Munzvimbo dzeindasitiri, porosity yakakosha nekuti:
*Inofambisa Fluid Flow: Inobvumira magasi kana zvinwiwa kupfuura nemukati mechinhu, zvichiita kuti zvive zvakanakira kusefa, aeration, uye mamwe mafambiro-akavakirwa maitiro.
* Inowedzera Surface Area: Yakawanda pamusoro penzvimbo mukati mevhoriyamu imwechete inosimudzira kusangana neyakapoterera nharaunda, iyo yakakosha kune maitirwo akaita se catalysis kana kemikari kuita.
Mabhenefiti ePamusoro Surface Nzvimbo yeMaapplication
Iyo yakakwirira yepamusoro nzvimbo ye sintered zvinhu inopa akawanda mabhenefiti:
1.Kuwedzera Filtration Efficiency:
Iyo yakakura pamusoro penzvimbo inobvumira sintered mafirita kuti atore zvimwe zvimedu, achivandudza mashandiro awo mumashandisirwo akaita semhepo, gasi, kana kusefa kwemvura.
2.Enhanced Chemical Reactions:
Mune catalytic process, iyo yepamusoro nzvimbo inopa mamwe anoshanda masaiti ekuita, kuwedzera kushanda kwemaitiro.
3.Better Gasi Diffusion:
Mune masisitimu emhepo, sematombo ecarbonation, iyo yakawedzera nzvimbo yenzvimbo inobatsira kuparadzira magasi zvakaenzana uye zvine hungwaru, zvichitungamira kune nekukurumidza uye kunoenderana mhedzisiro.
Muchidimbu, nzvimbo yakakwirira yepamusoro uye porosity yezvinhu zvakasvibiswa zvinoita kuti zvikoshese mumashandisirwo mazhinji emaindasitiri, zvichipa hunyanzvi hwekuita, kuita, uye kuita zvakasiyana.
