Sijonge phambili kumbuzo wakho ongaphezulu.
inkcazelo
I-PG Coated Carbon Crucible yimveliso egayiweyo esekwe ngokukodwa. Iqhele ukusetyenziselwa ukufunxa, ukunyibilika kunye nokubekwa kwemathiriyeli kumaqondo obushushu aphezulu nakwimo engqongileyo yevacuum, kwaye idlala indima ephambili kwiinkqubo zokufunxa umphunga ngakumbi. Uyilo olungundoqo kukusebenzisa iipropathi ezigqwesileyo zomzimba zePyrolytic Graphite ukugquma udonga lwangaphakathi okanye umphezulu wonke we-crucible, ngaloo ndlela uphucula ukumelana nobushushu obuphezulu be-crucible, ukunganyaniseki kweekhemikhali kunye ne-thermal homogeneity.
Ulwakhiwo lweempawu:
IMatriki yeMatrix kunye neSakhiwo sokuXhobisa:
I-Susceptor Material: I-graphite crucibles yethu yenziwe ngezinto zegraphite njenge-substrate yokuqinisekisa amandla omatshini kunye nokumelana nokushisa.
I-Pyrolytic Carbon (i-PyC) I-Coating: Uluhlu lwe-high-purity, i-crystalline pyrolytic graphite ifakwe ngokufanayo ngaphakathi okanye ngaphandle kwe-crucible ngokusebenzisa inkqubo ye-Chemical Vapor Deposition (CVD). Ubukhulu bengubo yi-30 µm ngokungagqibekanga. I-coating ifakwe kwaye i-anisotropic kakhulu phakathi kweengqimba kwicala lokukhula kwekristale. Ukucoceka kwengubo kudlula i-99.999% kwaye umxholo wokungcola ungaphantsi kwe-10 ppm, eyenza ukuba ifaneleke ngokukodwa kwiinkqubo ezineemfuno ezingqongqo zokucoceka. Sikwaxhasa ukutyeba okulungiselelweyo ngokweemfuno zakho.
Ukutywinwa kunye nokumelana nokhukuliseko:
Iingubo zethu zine-porosity ephantsi kakhulu kunye nomphezulu ogudileyo (umz. isibuko-ipolishiwe) kwaye ngoko ke ikhusela i-substrate ngokuchasene nokusabela kweekhemikhali phakathi kwezinto ezityhidiweyo kunye nesiseko se-crucible material kumaqondo aphezulu okushisa, ngaloo ndlela kwandisa ubomi benkonzo ye-crucible.
Kwi-vacuum kunye ne-inert atmosphere, i-pyrolytic graphite ibonisa ukuxhathisa ukukhukuliseka okugqwesileyo, iqinisekisa ukuba izinto eziphathekayo aziyi kungcoliswa yi-chemical reaction kunye nesitya okanye ngokungena kwindawo yokushisa ephezulu.
PG Coated Carbon Crucible Packaging
I-Pyrolytic Graphite Coated Crucible yethu iya kuxutywa kunye neekhreyithi zokhuni ezixineneyo kunye nesixa esikhulu sogwebu, kwaye iphathwe ngononophelo ngexesha lokugcinwa kunye nokuthutha ukugcina umgangatho wokuqala weemveliso zethu. Sijonge phambili kumbuzo wakho ongaphezulu!

izicelo
Indima eyodwa ekuphuhliseni umphunga:
1. Ulawulo lokufudumeza olufana nolwelo kunye nokuphuma komphunga:
I-graphite ye-pyrolytic efakwe eludongeni lwangaphakathi lwe-crucible inokubonelela nge-conductivity efanelekileyo ye-thermal ukuqinisekisa ukuhanjiswa kweqondo lokushisa elifanayo ngexesha lokufudumala, ukwenzela ukuba izinto ezinokuthi zikhutshwe zibe ngumphunga zikwazi ukukhupha ngokuzinzileyo kunye ngokufanayo kwi-vacuum.
2. Thintela ukusabela kweekhemikhali kunye nokungcoliseka:
I-thermal conductivity ephezulu ye-pyrolytic graphite iqinisekisa ukuba izinto ezikhutshiweyo (umzekelo i-aluminium) zifudunyezwa ngokufanayo, eziphucula umgangatho wokugquma; okwangoku, i-inertness yekhemikhali ye-PG ithintela isinyithi esinyibilikisiweyo ukuba singaphenduli kunye ne-crucible, ethintela ukuveliswa kokungcola kunye nokungcoliseka okunokwenzeka.
3. Ukuphucula uzinzo kunye nokuphinda-phinda:
Ngenxa yokumelana nobushushu obuphezulu kunye neempawu ezisezantsi zokwanda kwe-thermal, ukusetyenziswa kwe-PG Coated Carbon Crucible kunokunciphisa kakhulu ukuguquguquka kwenkqubo okubangelwa kukuguquguquka kwamaqondo obushushu okanye ukufudumeza kwasekhaya, ngaloo ndlela kuphuculwe ukuhambelana kwemveliso. Umzekelo, kwi-electron beam evaporation, iicrucibles zeGraphite ezine-PG coating zinokumelana nebhombu yemiqadi ye-electron yamandla aphezulu, ukugcina uzinzo kunye nokuthintela imathiriyeli ukuba ingaguquguquki kwaye iphume kulawulo.
4. Yandisa ubomi benkonzo yezixhobo:
I-porosity ephantsi kunye nokuxhathisa okuphezulu kwe-Pyrolytic Graphite coating kunciphisa ngokufanelekileyo ukukhukuliseka kwezinto. Ngokomzekelo, kwinkqubo yokucoca i-vacuum, i-Pyrolytic Graphite Crucible ingasetyenziselwa ngokuqhubekayo kwiiyure ze-24-52, ezinciphisa kakhulu ukuphindaphinda kokutshintshwa kunye neendleko zokuvelisa.
