Gwiritsani ntchito chidziwitso (dinani kuti muwerenge zambiri)

1.Fufuzani kukana kwa silicon carbide heat element mu batch yomweyi musanatsegule kulongedza, ikani kukana kwapafupi kwambiri mu gawo lomwelo, zomwe zingapangitse kutentha kwa ng'anjo kukhala yunifolomu, kukana komwe tidzalemba kumalo ozizira.

2.Chifukwa chakuti silicon carbide ndi chinthu cholimba komanso chosasunthika, musayese kukonza pamene mukuyiyika, imapanga kuti ikhale yosunthika momwe mungathere, zikutanthauza kuti ikhale yosunthika ndipo imatha kutuluka mosavuta mutayiyika.Chotenthetsera cha silicon carbide chimatha kuyika ndi dangle kapena lathyathyathya.

3.The silicon carbide heat element controller imagwiritsa ntchito thyristor control, kotero mphamvu imatha kusinthika, mphamvu yovotera ya wowongolerayo iyenera kukhala nthawi 2-3 kuposa mphamvu yomwe idavotera ng'anjo, motero kumatalikitsa moyo wa silicon carbide Heating element, kugwiritsa ntchito. m'njira yabwino.

4.Kusankha njira yolumikizira yolumikizira kumadalira kukula ndi kukana kwa silicon carbide heat element.

5.The latsopano silicon carbide Kutentha element ayenera kuonjezera mphamvu pang'onopang'ono mu Kutentha ndondomeko, kusiyana pakati pa silicon carbide Kutentha element ndi kutentha ng'anjo ndi osachepera, motero kutalikitsa silicon carbide Kutentha element life.after kukhazikitsa silicon carbide Kutentha element, kufala mphamvu motere: Choyamba ikani mphamvu 30% -40% ya mphamvu kamangidwe preheat mphindi 20 -40 mphindi, ndiye kuchuluka kwa 60% -70% ya kapangidwe mphamvu makulitsidwe20 mphindi -30 mphindi, pambuyo Kutentha kwa silicon carbide heat element ndi ng'anjo kumakhala koyenera, ndiye yonjezerani mphamvu pang'onopang'ono, magetsi ojambulidwa ndi amakono mpaka kutentha kufika pa kutentha komwe mukufuna, izi ndizomwe zimagwiritsidwa ntchito pogwiritsira ntchito magetsi ndi magetsi a silicon carbide heat element, Mkati mwazomwe zilipo panopa. ikhoza kukhazikitsidwa kuwongolera kutentha kwadzidzidzi, pamene kukana kunakhala kwakukulu kuonjezera voteji yoyenera, kupanga silicon carbide heat element kuti maintain mphamvu yokhazikika

6. Pambuyo ng'anjo kukonzekera, pamene silicon carbide Kutentha chinthu Kuwotcha ife kuika tebulo motere: Pamene kufala mphamvu wakhazikitsidwa kuyamba ntchito 40% mphamvu ya mphamvu yachibadwa, kutentha kwa mphindi 20, ndiye kuonjezera kutentha kwa kutentha ankafuna. kwa mphindi 10 mpaka 30 mphindi, ndiyeno ikani nthawi yogwira.

7.Musangoyang'ana voteji kapena panopa pogwiritsira ntchito silicon carbide heat element, chifukwa mukamagwiritsa ntchito kukana kumakhala kokulirapo pang'onopang'ono (voltage idzakhala yayikulu komanso yamakono idzakhala yaying'ono), pamene mphamvu yowonjezera imakhala yosasinthasintha, ndiye kutentha kumakhala kosasintha.

8.Ngati silicon carbide Kutenthetsa element kuonongeka pambuyo ntchito miyezi, musasinthe kwa wina watsopano, kusintha pa ntchito silicon carbide Kutenthetsa element, ndicho chifukwa kukana adzakhala lalikulu pamene ntchito, kukana latsopano adzakhala. kukhala yaying'ono kwambiri, ngati mugwiritsa ntchito yatsopano kutentha kumakhala kosiyana ndi silicon carbide Heating element, kotero mutha kusintha yogwiritsidwa ntchito, zomwe zingapangitse kukana kwa zinthu zotentha kuyandikira. zinthu, chonde sinthani zinthu zonse zotenthetsera kukhala zatsopano, ndiye zogwiritsidwa ntchito mutha kuzisintha mukazifuna.

9.Kukana kudzakhala kokulirapo mukamagwiritsa ntchito chotenthetsera, ngati kutentha sikungakhutire pamene voteji ifika pamwamba kwambiri, chonde sinthani kugwirizana, monga kugwirizanitsa mndandanda kungasinthe kufanana, kusintha kwa nyenyezi ku kugwirizana kwa delta, inu muyenera kusintha kulumikizana kumadalira wowongolera wanu.

10.Oxidi yachitsulo ndi slag ndi zinthu zina mu ng'anjo ziyenera kutsukidwa pakapita nthawi, musazisunge mu ng'anjo, ngati zigwirizanitsa chinthu chotenthetsera kuti chiwonongeke.

11.Kugwiritsa ntchito mosalekeza kudzakhala ndi moyo wautali kuposa kugwiritsa ntchito kwapakatikati.

12.Zomwe mukufuna kuti zitenthedwe zisakhale ndi chinyezi chambiri, kuti mupewe kutentha kwa chinthu, yesetsani kupewa kukhudzana mwachindunji ndi zinthu zamchere.

13.Kutentha kwa silicon carbide Kutentha kwazinthu kuyenera kupitilira 1550 ℃.

Kupaka (dinani kuti muwerenge zambiri)

SICTECH Silicon carbide heat element ndi mtundu wa filimu yopangira, yomwe imakutira pamwamba pa malo otentha pambuyo popanga silicon carbide heat element, imatha kukulitsa moyo wa silicon carbide heat element pamalo ogwiritsidwa ntchito mwapadera, Imatha kupatukana ndi mpweya. kufulumizitsa ukalamba wa silicon carbide heat element, kuteteza silicon carbide heat element, kuti mumve zambiri za zokutira chonde onani mawu oyambira awa:

1. Kupaka kwa T: ❖ kuyanika uku kukugwiritsidwa ntchito pochepetsa kuchuluka kwa okosijeni pakugwiritsa ntchito bwino, pangani chinthu chotenthetsera cha silicon carbide kuwonjezera moyo wantchito wa 30-60%.

2. D zokutira: zokutira izi zimagwiritsidwa ntchito ngati nayitrogeni

3. S ❖ kuyanika: ❖ kuyanika uku akugwiritsa ntchito mu magawo atatu ndodo (W mtundu wa silicon carbide heat element) galasi yoyandama

4. Q zokutira: zokutira izi zikugwiritsidwa ntchito ngati nthunzi kapena haidrojeni
