Kungani izikhwama zakho zokuhlanza zaphuka?
Ikakhulu ngenxa yezizathu ezimbili: ukwakheka kokufaka okungalungile noma izinto zokupakisha ze-vacuum:
Uma usayizi wakho wokupakisha oklanyelwe umncane kunomthamo wakho, isikhwama kufanele sephulwe, kuvame ukwenzeka ekupakisheni kwe-vacuum, ngoba umoya ususwe ngokuphelele esikhwameni sokupakisha. Ifilimu lokupakisha lizoxhumana ngqoizimpahla ngaphakathi bese ugoqa kahle izimpahla, okuzonciphisa indawo yokusebenzisa isikhwama sokupakisha. Ngakho-ke lapho ukuklama usayizi wesikhwama sokupakisha se-vacuum, shiya isikhala esanele esanele kubaluleke kakhulu.
Ngaphezu kwalokho, ngoba isikhwama sokupakisha sikusonga ngokuqinile ukudla, uma ukudla kuqukethe izingxenye eziqinile, futhi uma impahla yesikhwama sokupakisha ingenzima ngokwanele, noma ubukhulu bungagqinsi ngokwanele, ingxenye eqinile nayo izobhoboza isikhwama sokupakisha ngesikhathi sokuhamba nokugcinwa.
Ngakho-ke ngokujwayelekile sizokwenza ukuhlolwa okulandelayo ukuhlola ubukhulu besikhwama se-vacuum:
Izici zomzimba nezomshini zokupakisha kokudla-njengamandla we-tensile nokunwebeka ngesikhathi sekhefu, ukumelana nokubhoboza, ukumelana nomthelela we-pendulum, amandla we-peel, njll., Angahlulela ngokuqinile ubunzima, ukubhoboza ukumelana, ukumelana nomthelela neminye imishini ebonakalayo yesikhwama sokupakisha isheke ukuthi ukusebenza kuyahlangabezana yini nezidingo zokupakisha, ukugcina, ukustaka nokuhamba. (Kuhlobene nokuqukethwe, ubukhulu be-isikhwama sokupakisha, indlela yokuhamba nefomu lokupakisha)
Ukufakwa uphawu kokufakwa kokudla, njengokuhlolwa kwengcindezi okuqhamukayo, okunganquma indawo lapho kuphuka khona isikhwama nalapho amandla emishini ebuthakathaka khona. Isibonelo, isivivinyo samandla wokufaka uphawu lokushisa singanquma ukuthi ngabe ukushisa-amandla wokufaka uphawu ahlangabezana nezidingo zokuvuselelwa kokudla ngaphakathi, futhi anqume izingxenye ezingavaliwe kahle nokufana komphumela wokuvala ukushisa.
Umhloli wamandla wokuvuza nokubeka uphawu akakwazi ukuthola amandla okuphuka okuphezulu kwesikhwama sokupakisha esiguquguqukayo, kepha futhi avivinye isikhathi sokuphuka kwesikhwama sokupakisha ngokusetha ingcindezi esetshenzisiwe. Isakhiwo sesitaki singakhiwangokusho kwedatha yokuhlola, kanye nemingcele yenqubo yokufaka uphawu lokushisa ingahle ilungiswe ukuze ithuthukise ukusebenza kwe-Packaging, noma ihlaziye izinkinga esakhiweni sokupakisha ngokuya ngesikhundla sesikhwama sokupakisha esiguquguqukayo ukudabuka.
