Indlela echanekileyo yokwandisa ubomi benkonzo ye-quartz tube
(1) Unyango olungqongqo lokucoca. Ukuba ixabiso elincinci leentsimbi ze-alkali ezifana ne-sodium kunye ne-potassium kunye neekhompawundi zabo zingcolile phezu kweglasi ye-quartz, ziya kuba yi-crystal nuclei xa zisetyenziswe kumaqondo aphezulu kwaye ziya kukhanya ngokukhawuleza, zibangele ukuchithwa. Ngoko ke, ngaphambi kokusetyenziswa, qiniseka ukuba udibanise ityhubhu ye-quartz kwi-5-20% ye-hydrofluoric acid imizuzu emi-5 ukuya kwe-10, uze uyihlambe ngokupheleleyo ngamanzi adibeneyo, kwaye ekugqibeleni uyisule nge-gauze ye-degreasing kwaye uyomise. Umbhobho we-oven emva kokumisa unqatshelwe ngokungqongqo. Bamba ngqo ngezandla zakho.
(2) Ukulungiswa kobushushu obuphezulu. Xa isithando somlilo esitsha sisebenza okanye sitshintshwe ngesithando somlilo esitsha, kufuneka sibekwe phantsi konyango lwangaphambili.
(3) Nceda unikele ingqalelo ekhethekileyo ku-573″C. I-573 * C yindawo yokuguqulwa kwekristale yequartz. Nokuba iyafudumeza okanye iyaphola, kufuneka idlule kweliqondo lobushushu ngokukhawuleza.
(5) Xa umbhobho wequartz ungasebenzi, ubushushu bufanele buthotywe, kodwa bufanele bungabi ngaphantsi kwama-800°C.
(6) Zama ukukuphepha ubushushu nengqele ngokungeyomfuneko. Nangona iglasi yequartz inozinzo olululo lwe-thermal, iglasi yequartz opaque okanye iglasi yequartz ebonakalayo enobukhulu obungaphezulu kwe-5mm ithanda ukuqhekeka xa ubushushu butshintsha kakhulu. Ngokukodwa izixhobo zeglasi ze-quartz ezinkulu ezinezakhiwo eziyinkimbinkimbi zihlala zinexinzelelo lwangaphakathi, olulula Ukuba luqhuma, lumka xa usebenzisa.
(7) Inkxaso ngokupheleleyo kunye nokusetyenziswa kwe-flip. I-deformation ephezulu yokushisa kweglasi ye-quartz ayinakuphepheka. Abasebenzisi kufuneka banikele ingqalelo ekunciphiseni inani le-deformation. Ukufakelwa kwemikhono yokufudumeza i-corridor anti-corridor kunokunciphisa ukuguqulwa kweqondo lokushisa eliphezulu lombhobho we-quartz, kunye nenkxaso epheleleyo kunye nobude betyhubhu ye-quartz inokwandisa ubomi benkonzo yombhobho we-quartz ngama-2 ~ 3 amaxesha. Xa ityhubhu yequartz ingena kwi-deformation encinci yokugoba. Ityhubhu yequartz inokujikelezwa i-180 *. Xa ityhubhu ye-quartz idlula i-elliptical deformation, ilitye linokuba
Ibhubhu yaseBrithani ijikeleza i-90 *, enokwandisa ubomi bayo benkonzo.
