Indlela efanele yokwelula impilo yesevisi ye-quartz tube
(1) Ukwelashwa okuqinile kokuhlanza. Uma inani elincane kakhulu lezinsimbi ze-alkali ezifana ne-sodium ne-potassium nezinhlanganisela zakhona zingcoliswa ebusweni bengilazi ye-quartz, zizoba yi-crystal nuclei uma zisetshenziswa emazingeni okushisa aphezulu futhi zizocwebezela ngokushesha, kubangele ukuhlehla. Ngakho-ke, ngaphambi kokusetshenziswa, qiniseka ukuthi ucwilisa ithubhu ye-quartz ku-5-20% ye-hydrofluoric acid imizuzu engu-5-10, bese ugeza ngokugcwele ngamanzi angcolile, futhi ekugcineni usule nge-gauze yokugcoba bese uyomisa. Ishubhu ye-ovini ngemuva kokumiswa ivinjelwe ngokuqinile. Thinta ngqo ngezandla zakho.
(2) Ukwelashwa kwangaphambi kwezinga lokushisa. Uma isithando somlilo esisha senziwa sisebenze noma sithathelwa indawo isithando somlilo esisha, kufanele sibe ngaphansi kokushisa okuphezulu.
(3) Sicela unake ngokukhethekile u-573″C. I-573*C iyindawo yokuguqulwa kwekristalu ye-quartz. Kungakhathaliseki ukuthi liyashisa noma liyapholisa, kufanele lidlule leli phuzu lokushisa ngokushesha.
(5) Lapho ishubhu le-quartz lingasebenzi, izinga lokushisa kufanele lehliswe, kodwa akufanele libe ngaphansi kuka-800°C.
(6) Zama ukugwema ukushisa nokugodola okungadingekile. Nakuba ingilazi yequartz inokusimama okuhle kokushisayo, ingilazi yequartz ekhanyayo noma ingilazi yequartz ekhanyayo enogqinsi olungaphezu kuka-5mm ajwayele ukuqhekeka lapho izinga lokushisa lishintsha kakhulu. Ikakhulukazi izinsimbi zengilazi ze-quartz ezinkulu ezinezakhiwo eziyinkimbinkimbi ngokuvamile zinengcindezi yangaphakathi, okulula Uma iqhuma, qaphela uma uyisebenzisa.
(7) Ukusekela ngokugcwele nokusebenzisa flip. Ukuguqulwa kwezinga lokushisa eliphezulu kwengilazi ye-quartz akunakugwenywa. Abasebenzisi kufanele banake ukuze banciphise inani le-deformation. Ukufakwa kwemikhono yokushisa yephaseji elwa nokuwa kunganciphisa ukuwohloka okuphezulu kwezinga lokushisa kweshubhu le-quartz, futhi ukusekelwa okugcwele ngobude beshubhu ye-quartz kunganweba impilo yesevisi yeshubhu le-quartz izikhathi ezi-2 ~ 3. Lapho ithubhu ye-quartz iguquguquka kancane. Ishubhu yequartz ingazungeziswa ngo-180*. Lapho ithubhu ye-quartz idlula i-elliptical deformation, itshe lingaba
I-tube yaseBrithani ijikeleza i-90 *, enganweba impilo yayo yesevisi.
