Iinkcukacha zeMveliso

Iithegi zeMveliso

Sicinga ukuba abathengi bacinga ntoni, ukungxamiseka kokungxamiseka kokuthatha amanyathelo kwizinto ezinomdla womthengi womgaqo-siseko, ukuvumela umgangatho ophezulu ophezulu, ukuhla kweendleko zokusetyenzwa, uluhlu lwamaxabiso lusengqiqweni ngakumbi, luphumelele amathemba amatsha kunye nabadala ukuxhaswa kunye nokuqinisekiswa. Ilabhoratri ye-silica crucible, Izinto eziphambili zenkampani yethu zisetyenziswa ngokubanzi kwihlabathi liphela; I-80% yeemveliso zethu kunye nezisombululo ezithunyelwa eMelika, eJapan, eYurophu nakwezinye iimarike. Zonke izinto ezamkelekileyo ngokunyanisekileyo iindwendwe ziza kutyelela umzi-mveliso wethu.

Ukuqulunqwa kwezinto
Izikhephe zethu zaselabhoratri zenziwe nge-silica ecocekileyo (i-SiO₂), into eyaziwa ngokubanzi ngeempawu zayo ezibalaseleyo zokushisa kunye neekhemikhali:

Ubunyulu: Izibonda zethu zenziwe nge-45% ye-silica ecocekileyo, eqinisekisa ukuchasana nokungcola, ukugcina ingqibelelo yovavanyo lwakho kunye novavanyo.
Indawo yokunyibilika ePhezulu: Ngendawo yokunyibilika ye-1710 ° C, i-silica ifanelekile kwizicelo ezifuna ukusebenza ngamaqondo aphezulu kakhulu. Oku kuluncedo ngakumbi kwiilabhoratri eziqhuba uvavanyo kwisinyithi, iiseramikhi, kunye nemathiriyeli echasayo.
Ukwandiswa kweThermal ephantsi: I-coefficient ephantsi yokwandiswa kwe-thermal inciphisa umngcipheko wokuqhekeka phantsi kokufudumeza ngokukhawuleza okanye imijikelo yokupholisa, okwenza i-crucible ibe yinto ehlala ixesha elide kwiindawo eziguquguqukayo ze-thermal.

Ukusebenza kweThermal kunye neMechanical
Indawo yaselabhorethri ikholisa ukuba phantsi kweemeko zobushushu obugqithisileyo. I-silica crucibles yethu igqwesa ekugcineni uzinzo kumaqondo obushushu ukuya kuthi ga kwi-1600 ° C, ezenza zisebenze kakhulu kwizicelo ezinje:

Ukunyibilika kwesinyithi kunye nokunyibilikiswa: Kufanelekile ukuphatha isinyithi esityhidiweyo njengobhedu (indawo yokunyibilika: 1085°C), apho ukuchaneka kulawulo lobushushu kubalulekile.
Uhlalutyo lwe-Thermal: Ilungele iinkqubo ezifana nohlalutyo oluhlukeneyo lwe-thermal (i-DTA) okanye i-calorimetry yokulinganisa i-calorimetry (DSC), apho ukusebenza kwezinto ezizinzile kumaqondo aphezulu kubalulekile.
Ngombulelo wokuxhathisa ukothuka kwe-thermal, ezi crucibles zinokunyamezela utshintsho olukhawulezayo lobushushu ngaphandle kokonakala okanye ukuqhekeka, zizenze zigqibelele kwiinkqubo zaselabhoratri ezifuna ukufudumeza rhoqo kunye nokupholisa imijikelo.

Enkosi kwaboukuxhathisa ukothuka kwe-thermal, ezi zixhobo ziyakwazi ukunyamezelautshintsho olukhawulezayo lobushushungaphandle kokonakala okanye ukuqhekeka, kubenza bagqibelele kwiinkqubo zaselabhoratri ezifuna ukufudumeza rhoqo kunye nemijikelo yokupholisa.

Ukunyangwa kweMichiza kunye nokuzinza

I-silica crucibles inikezelainertness ephezulu yeekhemikhali, ebaluleke kakhulu xa usebenza ngeentsimbi ezisebenzayo, izinto ezidliwayo, okanye iioksidi ezinyibilikisiweyo. I-crucibles imelana neempendulo kunye ne-acids ezininzi kunye neziseko, kuqukaiialkalikwayeiioksidi zesinyithi, ukuqinisekisa ukuba iziphumo zakho zovavanyo zihlala zingangcolisekanga.

Ukunyangwa koMhlwa: Ukuchasana kwe-silica kwi-oxidation kunye ne-corrosion iqinisekisa ukuba indawo ye-crucible ayithobi nangona ngexesha lokuvezwa kwezinto ezinobundlobongela.
Ukugcinwa Kobunyulu: Uzinzo lwekhemikhali ye-silica edibeneyo igcina ubunyulu besampulu evavanywayo, ibalulekile kwizicelo zohlalutyo kunye nezifundo zesayensi yezinto.

Uyilo kunye nosetyenziso kwiiSetingi zeLabhoratri

Yenzelwe iingcali zaselabhoratri, izixhobo zethu ze-silica crucibles zifumaneka kwiimilo ezahlukeneyo kunye nobukhulu ukuze zilingane neemfuno zakho zovavanyo.
