Isikhathi Sokupholisa Sezingxenye Ezibunjiwe Zomjovo

Ukubalwa Kwesikhathi Sokupholisa Sezingxenye Ezibunjiwe Zomjovo Wepulasitiki.

Njengomshini wokubumba umjovo,phakathi ukukhiqizwa komjovo, isikhathi sokupholisa sezingxenye ezibunjwe ngomjovo wepulasitiki sithatha cishe 80% wawo wonke umjikelezo wokukhiqiza umjovo. Ukupholisa okungekuhle kuvame ukuphumela ku-warpage yomkhiqizo noma kukonakala kwendawo, okuthinta ukuzinza kwe-dimensional yomkhiqizo. Ukuhlelwa okunengqondo komjovo, ukubamba ingcindezi kanye nesikhathi sokupholisa kungathuthukisa ikhwalithi yomkhiqizo kanye nokukhiqiza.

Isikhathi sokupholisa sengxenye ngokuvamile sibhekisela esikhathini kusukela lapho ukuncibilika kwepulasitiki kugcwele umjovo isikhunta umgodi lapho ingxenye ingavulwa futhi ikhishwe. Isikhathi esijwayelekile sokuvula isikhunta ukuze kukhishwe izingxenye ngokuvamile sisekelwe eqinisweni lokuthi izingxenye zelashwe ngokugcwele, ube namandla athile nokuqina, futhi ngeke ikhubazeke noma iqhekeke lapho isikhunta sikhishwa.

Ngisho noma uhlobo olufanayo lwepulasitiki lusetshenziselwa ukubumba, isikhathi sayo sokupholisa siyahlukahluka ngobukhulu bodonga, izinga lokushisa lepulasitiki elincibilikisiwe, izinga lokushisa elibunjiwe lengxenye ebunjiwe, kanye nezinga lokushisa lomjovo wesikhunta.

Ifomula yokubala isikhathi sokupholisa 100% kahle kuzo zonke izimo akukakashicilelwa, kodwa amafomula kuphela angabalwa ngesisekelo sokuqagela okufanele. Ifomula yokubala nayo iyahluka kuye ngencazelo yesikhathi sokupholisa.
Okwamanje, Okulandelayo izindinganiso ezintathu ngokuvamile zisetshenziswa njengesisekelo senkomba sesikhathi sokupholisa:

① Izinga lokushisa lesendlalelo esimaphakathi sengxenye ewugqinsi yengxenye ebunjiwe yomjovo wepulasitiki, kanye nesikhathi esidingekayo ukuze kuphole sibe ngaphansi kwezinga lokushisa lokushintsha elishisayo lepulasitiki;

②Izinga lokushisa elimaphakathi esigabeni sezingxenye ezibunjiwe zomjovo wepulasitiki, kanye nesikhathi esidingekayo ukuze kuphole kuze kufike ekushiseni kwesikhunta komkhiqizo othile;

③ Izinga lokushisa longqimba olumaphakathi lwengxenye ewugqinsi yodonga lokubumba lwepulasitiki oluyikristale isikhathi esidingekayo ukuze kuphole ngaphansi kwendawo yalo yokuncibilika., noma isikhathi esidingekayo ukuze kufinyelelwe iphesenti elishiwo lokucwebezela.

Lapho uxazulula ifomula, ukucatshangelwa okulandelayo kwenziwa ngokujwayelekile:

①Ipulasitiki ijovwa ku- umjovo isikhunta, futhi ukushisa kudluliselwa kwisikhunta somjovo ukuze kupholiswe;

②Ipulasitiki esemgodini wokubumba isondelene nesikhunta futhi ngeke ihlukaniswe ngenxa yokuncipha kokupholisa.. Akukho ukumelana nokudlulisa ukushisa nokugeleza phakathi kokuncibilika nodonga lwesikhunta.

Izinga lokushisa lokuncibilika liyafana lapho lithinta udonga lwesikhunta. Leyo, lapho ipulasitiki igcwele emgodini wesikhunta, izinga lokushisa elingaphezulu lengxenye lilingana nokushisa kodonga lwesikhunta;

③Ngesikhathi sokupholisa izingxenye ezibunjiwe ngomjovo wepulasitiki, izinga lokushisa lobuso besikhunta somjovo lihlala lifana;

④Izinga lokushisa elingaphezulu kwesikhunta lomjovo liqinisekile; (inqubo yokugcwalisa ukuncibilika ithathwa njengenqubo ye-isothermal, futhi izinga lokushisa lempahla lifana)

⑤Ithonya le-orientation nokucindezeleka okushisayo kwepulasitiki ekuguqulweni kwengxenye kungashaywa indiva, futhi ubukhulu bengxenye abunawo umthelela ekushiseni kokuqina.

Uma unemibuzo ku umjovo udini ,plz ngicela ukubuza Iqembu le-FLYSE,sizokunikeza isevisi engcono kakhulu!
