Girazi kune girazi kuvhara

Mukugadzirwa kwezvigadzirwa zvine maumbirwo akaoma uye zvinodikanwa zvakakwirira, iyo imwe-nguva yekugadzira girazi haigone kusangana nezvinodiwa. Izvo zvinodikanwa kutora nzira dzakasiyana-siyana dzekuita kuti girazi uye girazi rekuzadza rivharwe kuti rigadzire zvigadzirwa zvine maumbirwo akaomarara uye kusangana nezvinodiwa, sekuisa chisimbiso che electro-optic yepakati uye akawanda makoramu akafumurwa machubhu, kuvharirwa kweelectron chubhu shell uye. core column, kuiswa chisimbiso kwecathode ray chubhu (yakadai seTV mufananidzo chubhu, nezvimwewo), Chisimbiso pakati peprotoplast nemuviri unesimba.

Kuiswa chisimbiso pakati pegirazi negirazi kunogadzirwa negirazi zvinhu, uye kemikari zvisungo pakati pazvo ndeye covalent yakasanganiswa chemistry yeion. Zvichienderana nemusimboti wekubatana kwehukama hwemakemikari mabhondi akafanana kana kufambira mberi kwemakemikari bond (yakafanana yekunyungudika musimboti), zvigadzirwa zvegirazi uye zvigadzirwa zvegirazi zvine zvinhu zvakanaka, uye kupindirana kunoenderana kunogona kugadzirwa zvakananga pachiratidziro panguva yekuisa chisimbiso.

Nzira dzegirazi kune girazi kuvhara

Girazi negirazi zvinogona kuvharwa nenzira dzinotevera.

(1) Kupisa kuvharika kwakananga kunogona kupisa nzvimbo yakanyunguduka yegirazi negirazi kupfava uye kunyungudutsa magineti, kuitira kuti zvigone kuiswa chisimbiso pamwe chete kuti zvizadzise zvinodikanwa zvekuvharirwa kwemhepo. Nzira dzekuisa chisimbiso dzinosanganisira murazvo muhombe pamwe nekuisa chisimbiso chegirazi, yakakwira induction kudziyisa chisimbiso uye murazvo wemagetsi munda wakasanganiswa kupisa chisimbiso.

(2) Kune mamwe maturusi asina kukodzera kupiswa zvakananga nemurazvo, girazi master batch rinogona kushandiswa kunama girazi negirazi negirazi solder.

(3) Kana iyo coefficient mutsauko pakati pemhando mbiri dzegirazi dzinofanirwa kunamwa yakakurisa uye isingakodzere kunyunguduka zvakananga, marudzi akati wandei enzira dzekuisa chisimbiso dzinogona kushandiswa.

Girazi repakati rine coefficient iri pakati pezviviri rinonyungudutswa uye rakanamwa zvakare.

Kudziisa self sealing

Nekupisa girazi munzvimbo mudiki, girazi remadziro panzvimbo yekudziya rinogona kusvika padanho rekurodha nekunyunguduka, kuitira kuti girazi rigone kuvharwa.

Nekuti thermal conductivity yegirazi idiki, yemuno kana diki yekudziya yemukati nzira inogona kushandiswa kugadzira girazi panzvimbo yekudziya inosvika kune yakapfava. Panguva ino, girazi rinogona kuvharwa.

Kuvimbika uye kusimba kwegirazi uye girazi rekuisa chisimbiso nzvimbo zvinoenderana necoefficient yavo yekuwedzera kwekupisa. Kana iyo coefficient of thermal pressure of mutual sealing girazi yakafanana kana musiyano uri mudiki, vanogona kuvharirwa zvakananga. Kunyatsotaura, kwete chete avhareji coefficient of thermal base of mutual chisimbiso girazi iri padyo, asiwo tembiricha yese kubva pakamuri tembiricha kusvika kune annealing tembiricha inodiwa, Iyo coefficient yekudziya kwemumvuri wekumanikidza inofanirwa kuenderana sezvinobvira. Maererano naYisuan, kana kusiyana kwekupisa kwekupisa kweZhiai kuri pasi pe10% muhutano hwose hwekushanda kwekushisa, kusungirirwa kwechisimbiso kunogona kudzorwa mukati mehutano hwakachengeteka, uye nzvimbo yakanaka yekuisa chisimbiso haizoputika.

(1) Zvinoenderana nemhando dzakasiyana dzekudziya, kuiswa chisimbiso kwegirazi negirazi zvinogona kupatsanurwa mumhando nhatu, kureva kupisa kwetsika hombe, kupisa kwakanyanya kwepasi uye hombe yemagetsi yekutanga kusanganisa kupisa. Nzira dzakasiyana dzekushisa uye nguva yekuvhura inogona kukamurwa kuita mhando nhatu: blanking type, butt joint type uye screen cone type. Nzira dzekupisa uye nzira dzekuisa chisimbiso dzakasiyana, asi maitiro ekushanda akafanana. Vese vanopinda nenzira nhatu: preheating, kuisa chisimbiso uye annealing.

Moto kupisa girazi kuvhara inogona kuva gasi (gasi, nezvimwewo) mweya (kana oksijeni) kupisa girazi redu, zadzisa girazi pakati pechisimbiso chefusion.

Iyo yakakwira induction yekudziya chisimbiso inoshandisa yemagetsi munda induction kudziyisa kugadzira iyo column uye main chubhu chisimbiso, icho chinonzi chisimbiso chepamusoro. Rudzi urwu rwechisimbiso nzira inowanzoshandiswa mumhando yeferrylight kumuromo. Girazi rinoparadzaniswa nemagetsi, uye haridi kupiswa uye kunyungudutswa pasi penzvimbo yakakwirira yemagetsi. Naizvozvo, graphite inowanzoshandiswa seyepakati kupisa muviri kugadzira girazi chubhu uye timu yemaitiro kuwedzera chisimbiso cheutsi, Pakupisa kwepamusoro, haizosanganiswa negirazi pamusoro, saka nzira yekugadzirisa iri nyore uye mutengo wakaderera. Naizvozvo, iyo mold yakagadzirwa nematombo inowanzoshandiswa seyepakati yekudziya muviri pakakwirira frequency. Panguva yekuisa chisimbiso, dombo rinopisa pamwe chete neforoma pamhepo yakawanda kuti ibwe ridziye. Kupisa kubva mukuumbwa kunopfavisa girazi. Iyo girazi chubhu inotsikirirwa pasi nekuda kwehuremu hwayo, uye pakupedzisira yakavharwa pamwe chete nechisimbiso chakafumurwa. Chimiro chenzvimbo yekuisa chisimbiso chinonyanya kuenderana nechimiro uye hukuru hwedombo mold.

Mukuiswa chisimbiso kwepakutanga kwemamwe maturusi, murazvo wemagetsi munda wakasanganiswa nekudziya kunyungudika chisimbiso unotora yakakwira yemagetsi kuvharisa munda.

Chisimbiso chemagetsi kwenguva pfupi). Chekutanga, murazvo unoshandiswa preheat skrini uye simba remuviri rinodzorwa pane imwe chinhambwe. Nekupisa, murazvo wekudziya unoshanduka kubva pakupfava kuenda kune wakaoma, uye skrini zvishoma nezvishoma inotamira kune koni. Kana nzvimbo yekuvharisa yechidzitiro nekoni ichidziya kusvika pakupfava, voltage yakakwira (inenge 10kV) inoiswa panzvimbo yekuvharisa kuita kuti maion mugirazi rakapfava riri panzvimbo yakavharwa iite magetsi. Kuburikidza nekufamba kwemaion, girazi rinonyunguduka zvakaenzana, izvo zvinovandudza kunaka kwekuvhara. Kana kudzvinyirirwa kwepamusoro kuchishandiswa uye nzvimbo yekuvhara inopiswa nemagetsi kuita kuti chisimbiso chinyunguduke zvachose, chidzitiro chinoenda kune vertebral body zvakare, uye yozodzokera shure. Panguva imwecheteyo, chinopisa uye peya ye graphite electrode inofambawo nekufamba kwechidzitiro, zvichiita kuti nzvimbo yekuisa chisimbiso yakati sandara uye yakavimbika.
