Inhlangano igcina umqondo wenqubo "ukuphathwa kwesayensi, ikhwalithi yephrimiyamu kanye nokusebenza kahle kakhulu, umthengi ophakeme Wokulethwa Okusha kwe-CAS 7803-62-5 Semiconductor Use Gas Silane/Silicon Tetrahydride, Manje sifuna ukubambisana okukhulu nakakhulu nabathengi baphesheya abathembele. ngemivuzo efanayo. Uma ungaba nentshisekelo cishe kunoma yisiphi isixazululo sethu, qiniseka ukuthi uzozizwa ungekho zindleko ukuze usishayele ukuze uthole imininingwane eyengeziwe.
Inhlangano igcina emcabangweni wenqubo othi “ukuphathwa kwesayensi, ikhwalithi ye-premium kanye nokubaluleka kokusebenza ngempumelelo, umthengi ophakemeI-China Silicon Tetrahydride neSilane, Ukuze ukwazi ukusebenzisa insiza evela olwazini olukhulayo ekuhwebeni kwamazwe ngamazwe, samukela abathengi abavela yonke indawo ku-inthanethi nokungaxhunyiwe ku-inthanethi. Naphezu kwezisombululo zekhwalithi ezinhle esizinikezayo, isevisi yokubonisana ephumelelayo nenelisayo ihlinzekwa ithimba lethu lenkonzo yochwepheshe ngemva kokuthengisa. Uhlu lwemikhiqizo kanye nemingcele enemininingwane kanye nanoma yiluphi olunye ulwazi olutholakalayo luthunyelwa kuwe ngesikhathi ngemibuzo yakho. Ngakho-ke sicela uxhumane nathi ngokusithumela ama-imeyili noma usishayele uma unemibuzo mayelana nenhlangano yethu. ungase futhi uthole ulwazi lwamakheli ethu ekhasini lethu lewebhu futhi uze enkampanini yethu ukuze uthole inhlolovo yendawo yokuthengisa kwethu. Siyaqiniseka ukuthi sizokwabelana ngokuzuzisane futhi sakhe ubudlelwano obuqinile bokusebenzisana nabalingani bethu kule ndawo yemakethe. Sibhekela phambili imibuzo yakho.

Ukucaciswa

I-sulphur tetrafluoride iyinhlanganisela ye-inorganic ene-molecular formula ye-SF4. Igesi engenambala, edlayo futhi enobuthi kakhulu endaweni ejwayelekile. Inesisindo samangqamuzana angu-108.05, indawo yokuncibilika engu -124°C, kanye nephuzu lokubila elingu -38°C. Kuyi-ejenti esebenza kakhulu futhi esetshenziswa kabanzi ekhethiwe ye-organic fluorinating. Ingakhetha ngokukhetha i-fluorinate carbonyl kanye namaqembu e-hydroxyl. Inesikhundla esingenakushintshwa ekukhiqizeni amakhemikhali amahle, izinto zekristalu ewuketshezi kanye nezimboni zemithi ezisezingeni eliphezulu. I-sulphur tetrafluoride iyi-ejenti ekhethiwe ye-organic fluorinating. Kuyigesi engenambala enephunga elinamandla elifana negesi yesulfure dioxide ngaphansi kwezinga lokushisa elivamile nokucindezela. Inobuthi futhi ayishi noma iqhume emoyeni; ku-600°C Izinzile kakhulu. I-hydrolysis enamandla emoyeni ikhipha intuthu emhlophe. Ukuhlangana nomswakama endaweni kungabangela ukugqwala okufana ne-hydrofluoric acid. I-hydrolyzed ngokuphelele ibe yi-sulphur dioxide ne-hydrofluoric acid, lapho i-hydrolyzed ngokwengxenye, ikhiqiza i-thionyl fluoride enobuthi, kodwa ingamuncwa ngokuphelele isixazululo esiqinile se-alkali ukuze ibe usawoti ongenabuthi nongenabungozi; ingancibilika ku-benzene. I-sulphur tetrafluoride okwamanje iyi-ejenti ekhethayo esebenza kakhulu ye-organic fluorinating esetshenziswa kabanzi. Ingakwazi ukukhetha ngokukhetha i-fluorinate i-carbonyl kanye namaqembu e-hydroxyl (ishintsha umoya-mpilo ezinhlanganisela eziqukethe i-carbonyl); isetshenziswa kakhulu kumakhemikhali amahle wezinto ezisezingeni eliphezulu zekristalu ye-liquid futhi Ukukhiqizwa kwezimboni ezisezingeni eliphezulu zemithi nezibulala-zinambuzane kunendawo engenakushintshwa. Ingasetshenziselwa igesi ye-elekthronikhi, i-chemical vapor deposition, i-ejenti yokwelashwa kwendawo, i-plasma etching eyomile nezinye izici eziningi. Isetshenziswa ku-organic synthesis, iyi-reagent evamile yokwenza ama-fluorocarbons. I-sulphur tetrafluoride igcinwa endaweni yokugcina impahla epholile, enomoya. Kufanele igcinwe ngokuhlukana nama-oxidants, amakhemikhali adliwayo, nezinsimbi ze-alkali, futhi kude nomlilo nemithombo yokushisa.

Isicelo:

① I-ejenti ye-Organic fluorination:
I-ejenti ephumelela kakhulu yokukhetha i-fluorinating isetshenziswa kakhulu ezintweni ezisezingeni eliphakeme ze-liquid crystal kanye nesibulala-zinambuzane esine-fluorine, imithi kanye ne-intermediates; ingasetshenziswa futhi njengegesi ye-electron, i-chemical vapor deposition, i-ejenti yokwelashwa kwendawo, i-etching eyomile, i-plasma nezinye izici.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;
②ISO umenzi wesitifiketi;
③Ukulethwa okusheshayo;
④Umthombo wezinto ezingavuthiwe ozinzile;
⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;
⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;Inhlangano igcina umqondo wenqubo "ukuphathwa kwesayensi, ikhwalithi yephrimiyamu kanye nokusebenza kahle kakhulu, umthengi ophakeme Wokulethwa Okusha kwe-CAS 7803-62-5 Semiconductor Use Gas Silane/Silicon Tetrahydride, Manje sifuna ukubambisana okukhulu nakakhulu nabathengi baphesheya abathembele. ngemivuzo efanayo.
