3 Izinzuzo zesikhwama se-PE semisebenzi enzima

A Isikhwama sokuhlunga se-PEinikeza izinzuzo ezintathu eziyinhloko ezindaweni zokusebenza ezinzima:

• Ukumelana nezinga lokushisa eliphezulu kugcina ukusebenza kuzinzile ekushiseni okukhulu.
• Ukumelana namakhemikhali kuvikela ezintweni ezinokhahlo.
• Ukuqina kuqinisekisa ukusetshenziswa okuhlala isikhathi eside, ngisho nangaphansi kwezimo ezinzima.

Lezi zici zihlangabezana nezinselele zezinhlelo zokusebenza zezimboni zesimanje.

1. Ukumelana Nokushisa Okuphezulu

Ukumelana nokushisa kwesikhwama sesihlungi se-PE

Izikhwama zokuhlunga ze-PE zigqama ezindaweni ezinzima lapho ukushisa kungonakalisa ukuhlunga. Bagcina ubuqotho besakhiwo emazingeni okushisa afinyelela ku-150°C (302°F), okubenza babe ukukhetha okuthembekile ezimbonini eziningi. Nakuba izikhwama ze-Teflon ne-PTFE zikwazi ukuphatha amazinga okushisa aphakeme nakakhulu, izikhwama zokuhlunga ze-PE zinikeza isisombululo esingabizi kakhulu sezinhlelo zokusebenza eziningi zokushisa okuphezulu. Isakhiwo sabo se-polymer esiyingqayizivele simelana nokuncibilika nokuguqulwa, okusiza ukuvimbela ukwehluleka kwesihlungi ngesikhathi sokusebenza okuqhubekayo.

Qaphela: Izikhwama zokuhlunga ze-PE zinikeza ibhalansi phakathi kokusebenza nokufinyeleleka, ikakhulukazi uma kuqhathaniswa nezinto ezibiza kakhulu zezinga lokushisa eliphezulu.

Imboni isebenzisa ekushiseni okukhulu

Izimboni eziningi zithembele ezikhwameni zokuhlunga ze-PE ukuze zigcine izinqubo zisebenza kahle ngaphansi kokushisa okukhulu. Nazi ezinye izinhlelo zokusebenza ezijwayelekile:

• Ukukhiqizwa kokudla: Amabhikawozi kanye nabakhiqizi bokudla okulula basebenzisa izikhwama zokuhlunga ze-PE ukuze bahlunge uwoyela namasyrups ngesikhathi sokucubungula izinga lokushisa eliphezulu.
• Ukukhiqizwa kwe-elekthronikhi: Lezi zikhwama zisiza ukususa izinhlayiya ezindaweni zokugeza zamakhemikhali ashisayo asetshenziswa ekukhiqizeni ibhodi lesifunda.
• Ukutholwa kwe-solvent: Izinsiza ezibuyisa izincibilikisi emazingeni okushisa aphakeme zincike ezikhwameni zokuhlunga ze-PE ukuze zigcine ubumsulwa nokuvikela okokusebenza.

Isikhwama sesihlungi se-PE siletha imiphumela engaguquki ezindaweni lapho ukushisa kuzolulaza ngokushesha ezinye izinto. Lokhu kwethembeka kunciphisa isikhathi sokuphumula kanye nezindleko zokunakekela, okwenza kube inketho ekhethwayo yemisebenzi enzima.

2. Ukumelana Kwamakhemikhali

Ukumelana namakhemikhali esikhwama se-PE

Isikhwama sokuhlunga se-PE sinikeza ukumelana okuqinile ezinhlobonhlobo zamakhemikhali. Izinto ze-polyethylene zimelela ama-asidi, ama-alkali, nezincibilikisi eziningi eziphilayo. Lokhu kumelana kusiza ukuvimbela ukuwohloka kwezikhwama kanye nokungcoliswa kwemikhiqizo ehlungiwe. Uma kuqhathaniswa nezinto ezifana nenayiloni, engadilika ezindaweni ezinzima, isikhwama sokuhlunga se-PE sigcina ukwakheka nokusebenza kwaso. Izimboni eziningi zikhetha le nketho ngekhono layo lokuphatha izinto ezinolaka ngaphandle kokulahlekelwa ukusebenza kahle kokuhlunga.

Ithiphu: Njalo hlola ishadi lokusebenzisana kwamakhemikhali ngaphambi kokukhetha isikhwama sokuhlunga sohlelo oluthile.

Izicelo ngamakhemikhali anokhahlo

Izimboni ezisebenza ngamakhemikhali aqinile zithembele ezikhwameni zokuhlunga ze-PE ukuze zihlunge ngokuphephile nangempumelelo. Nazi ezinye izimo zomhlaba wangempela:

• Izitshalo zokubuyisela i-solvent zisebenzisa lezi zikhwama ukuze zihlunge ukungcola kuzincibilikisi ezinamandla, zivikele kokubili okokusebenza kanye nemikhiqizo yokugcina.
• Izikhungo zokupakisha ze-cleanroom zincike ekuphikisweni kwamakhemikhali kwezikhwama zokuhlunga ze-PE ukuze kugcinwe izinto ezibucayi zingangcoliswa.
• Imisebenzi yokuqedela insimbi ngokuvamile isebenzisa lezi zikhwama ukuhlunga izixazululo ze-acidic noma ze-alkaline, ukuqinisekisa ukukhiqizwa okubushelelezi kanye nokuphila isikhathi eside kwemishini.

Isikhwama sokuhlunga se-PE sinikeza ukuthula kwengqondo ezindaweni lapho ukuchayeka kwamakhemikhali kuhlala njalo. Abasebenzi nabaphathi babika ukwehluleka kwezikhwama ezimbalwa kanye nesikhathi esincane sokuphumula, okuholela ekukhiqizeni okuphezulu kanye nezindleko zokunakekela eziphansi.

3. Ukuqina Ezimweni Ezinzima

Ukuqina kwesikhwama sesihlungi se-PE

Isikhwama sokuhlunga se-PE sigqama ngokwakhiwa kwaso okuqinile. Abakhiqizi baklama lezi zikhwama ukuze zibambe ingcindezi yomzimba, ukuhuzuka, nokusebenzisa ngokuphindaphindiwe. Impahla imelana nokudabuka nokubhoboza, ngisho nalapho kuvezwe izinhlayiya ezibukhali noma ukuphatha kabi. Abasebenzisi abaningi babika ukuthi lezi zikhwama zigcina umumo wazo nokusebenza kokuhlunga ngemva kwemijikelezo eminingi. Lokhu kuqina kunciphisa isidingo sokushintshwa njalo futhi kusiza ukulawula izindleko zokusebenza.

• Imithungo eqinisiwe: Ukuthunga okuqinile kuvimbela ukuvuza futhi kunwebe isikhathi sempilo yesikhwama.
• Izinto eziwugqinsi: Indwangu ye-polyethylene inikeza ukuvikeleka okwengeziwe ekugugeni nasekudabukeni.
• Ukusebenza okungaguquki: Isikhwama siyaqhubeka nokuhlunga ngempumelelo, ngisho nangemva kokuchayeka ezimeni eziyinselele.

Qaphela: Izinsiza ezisebenzisa izikhwama zokuhlunga ze-PE zivame ukubona ukuphazamiseka okumbalwa ngenxa yokwehluleka kwezikhwama.

Ukuphila isikhathi eside nolwazi lomsebenzisi

Abasebenzisi ezimbonini ezifana nokusebenza kwensimbi, ukucutshungulwa kwamakhemikhali, nokukhiqiza ukudla baxabisa impilo ende yesevisi yalezi zikhwama zokuhlunga. Abaphathi bezikhungo abaningi babelana ngempendulo eyakhayo mayelana nokuthembeka kwesikhwama sokuhlunga se-PE ekusebenzeni kwansuku zonke. Bagqamisa izinzuzo ezilandelayo:

• Isikhathi sokuphumula esincishisiwe: Izinguquko ezimbalwa zezikhwama zisho ukuphazamiseka okuncane ekukhiqizeni.
• Izindleko zokulungisa eziphansi: Izikhwama ezihlala isikhathi eside zidinga ukushintshwa kancane kancane.
• Ukuphepha okuthuthukisiwe: Izikhwama ezingahluleki ngaphansi kwengcindezi zisiza ukugcina indawo yokusebenza ephephile.

Isikhwama sokuhlunga se-PE siletha ukusebenza okuthembekile, ngisho nasezilungiselelweni ezinzima kakhulu. Lesi sithunzi sokuphila isikhathi eside sikwenza kube ukukhetha okuthenjwayo kwemisebenzi enzima.

• Ukumelana nezinga lokushisa eliphezulu, ukumelana namakhemikhali, nokuqina kwenza isikhwama sokuhlunga se-PE sihlukaniselwe imisebenzi enzima.
• Lezi zici zisekela ukuhlunga okuthembekile ezindaweni ezidinga kakhulu.
• Abaphathi bezindawo abafuna izixazululo ezisebenzayo zokuhlunga kufanele bacabangele le nketho ngokusebenza okungaguquki kanye nenani lesikhathi eside.
