I-China Eyenziwe Ngokwezifiso I-99.95% Isikebhe Esihlanzekile Se-Molybdenum Umkhiqizi Nomhlinzeki

Ngokwezifiso 99.95% Pure Molybdenum Boat Evaporation Thermal

Ngokwezifiso 99.95% Pure Molybdenum Boat Ukuhwamuka Okushisayo Isithombe Esifakiwe

Incazelo emfushane:

Izikebhe ze-molybdenum ezenziwe ngendlela oyifisayo ezingu-99.95% zivame ukusetshenziswa ezinqubweni zokuhwamuka okushisayo ukuze kufakwe ifilimu elincanyana ezimbonini ezinjengokukhiqiza i-semiconductor, optics kanye ne-electronics. Le mikhumbi yakhelwe ukuqukatha futhi ishise izinto ezihwamukayo, ibangele ukuthi ihwamuke futhi ifake ifilimu elincanyana ku-substrate.

Ubala kanjani izinga lokushisa lokuhwamuka?

Izinga lokushisa lokuhwamuka (okubizwa nangokuthi indawo yokubilisa) lento ingabalwa kusetshenziswa izindlela ezahlukahlukene, kuye ngedatha etholakalayo kanye nezimpawu ezithile zento. Nazi izindlela ezimbalwa ezijwayelekile zokubala izinga lokushisa lokuhwamuka:

1. Sebenzisa idatha yamakhemikhali: Izinga lokushisa lokuhwamuka kwento ngokuvamile lingatholakala kulwazi lwamakhemikhali noma ezincwadini. Izinto eziningi zinezindawo zokubilisa ezibhalwe kahle ngomfutho ojwayelekile (1 umkhathi). Lena indlela elula nenembe kakhulu yokunquma izinga lokushisa lokuhwamuka uma idatha itholakala.

2. Sebenzisa isibalo se-Clausius-Clapeyron: Izibalo ze-Clausius-Clapeyron zingasetshenziswa ukulinganisa ushintsho kumfutho womhwamuko wento njengomsebenzi wezinga lokushisa. Ngokuhlela i-logarithm yemvelo yokucindezela komhwamuko ngokumelene nokuphindaphinda kwezinga lokushisa, ukuthambeka komugqa ophumayo kungasetshenziswa ukubala i-enthalpy yokuhwamuka, okubuye kusetshenziselwe ukulinganisa indawo yokubilisa ngezingcindezi ezihlukene.

3. Sebenzisa idatha yokucindezela komhwamuko: Uma idatha yengcindezi yomhwamuko wento emazingeni okushisa ahlukene itholakala, ungasebenzisa isibalo sika-Antoine noma ezinye izibalo ze-empirical ukuze ulingane idatha futhi ulinganise indawo yokubilisa ngokucindezela okuvamile.

4. Sebenzisa ukulingiswa kokuguquguquka kwamangqamuzana: Kuzinto eziyinkimbinkimbi noma lapho idatha yokuhlola ilinganiselwe, ukulingisa kwe-molecular dynamics kungasetshenziswa ukubala izinga lokushisa lokuhwamuka ngokusekelwe ekuziphatheni kwama-molecule ngamanye nokusebenzisana kwawo.

Kubalulekile ukuqaphela ukuthi ukunemba kwezinga lokushisa elibaliwe lokuhwamuka kuncike kwikhwalithi yedatha kanye nendlela esetshenzisiwe. Lapho uphatha izinto eziyingozi, kubalulekile ukubonana nemithombo ethembekile futhi uqinisekise ukuthi izinyathelo zokuphepha ziyalandelwa.

Yiziphi izimo ezi-3 ezingcono kakhulu zokuhwamuka?

Izimo ezintathu ezifanele kakhulu ukuhwamuka yilezi:

1. Izinga lokushisa eliphezulu: Ukuhwamuka kwenzeka ngokushesha emazingeni okushisa aphakeme ngenxa yokuthi amandla okushisa akhuphukayo anikeza ama-molecule amandla amakhulu e-kinetic, okuwavumela ukuba anqobe amandla e-intermolecular futhi abaleke esigabeni soketshezi aye esigabeni segesi.

2. Umswakama ophansi: Umswakama womoya osendaweni uphansi futhi umehluko wengcindezi yomhwamuko phakathi koketshezi nomoya mkhulu, ovumela ukuhwamuka ngokushesha. Lapho umoya ugcwele umhwamuko wamanzi (umswakama ophezulu), izinga lokuhwamuka liyehla ngoba i-gradient yokuhlushwa yama-molecule amanzi asuka esigabeni soketshezi aye esigabeni segesi ayehla.

3. Indawo engaphezulu: Indawo enkulu yoketshezi evezwe emoyeni ozungezile ikhuthaza ukuhwamuka okusheshayo. Yingakho, isibonelo, izingubo ezimanzi zoma ngokushesha lapho zisakazwa kunokuba zihlanganiswe ndawonye, ngoba indawo eyengeziwe ivumela ama-molecule amaningi amanzi ukuba abaleke emoyeni.

Ndawonye, lezi zimo zisiza ukukhulisa izinga lokuhwamuka, okuvumela izinto ukuthi ziguquke zisuka kuketshezi ziye esigabeni segesi ngokuphumelelayo.
