Izinhlobo ezine eziyinhloko zezikhwama ze-FIBC uhlobo A (ezingaqhubi ugesi, zenzelwe izinto ezingenzi lutho kuphela), uhlobo B (ezikhiqiza ugesi omncane, zenzelwe izimpushana ezomile ezingenabungozi bezincibilikisi), uhlobo C (eziqhubayo, ezidinga ukufakwa emhlabathini ukuze zisetshenziswe ngokuphepha nezinto ezinokuvutha), nohlobo D (ezichitha ugesi omile, ezizifaka emhlabathini ngaphandle kwezixhumanisi zangaphandle). Zihluka kakhulu emandleni azo okuvikela ugesi omile, okunquma ukuthi yiziphi izinto nezindawo ezingasetshenziswa kuzo ngokuphepha.

Yebo, izikhwama eziningi ezinkulu ze-FIBC zenzelwe ukusetshenziswa izikhathi eziningi, uma nje zihlolwe kahle, zahlanzwa, futhi zagcinwa phakathi kokusetshenziswa. Inani lokusetshenziswa kabusha lincike ezintweni ezinjengokugqwala kwempahla, ukuchayeka emvelweni, izindlela zokuphatha, kanye nesilinganiso sokuphepha sokuqala sesikhwama. Hlala uhlola izikhwama ngokuphelele ukuthi azinalo yini umonakalo ngaphambi kokusetshenziswa ngakunye.

Ukuze uhlanganise isikhwama se-Type C FIBC ngendlela efanele, xhuma ithegi yokuhlanganisa yesikhwama noma iluphu yomhlaba endaweni eqinisekisiwe yomhlaba usebenzisa intambo yokuhlanganisa efanele kanye nesigxivizo. Qinisekisa ukuthi ukumelana nomhlaba kungaphansi kwama-10 ohms. Ukuxhumana komhlaba kufanele kugcinwe phakathi nokugcwalisa, ukuthutha, kanye nokusebenza kokukhipha. Ungaze usebenzise isikhwama se-Type C ngaphandle kokuxhuma intambo yomhlaba.

Izikhwama ze-Type C FIBC zidinga ukuxhunywa emhlabathini ukuze zikhiphe ugesi omile ngokuphepha emhlabathini, kuyilapho izikhwama ze-Type D FIBC zisebenzisa ubuchwepheshe obukhethekile bendwangu yokulwa nogesi obukhipha amandla ngokusebenzisa i-corona discharge ngaphandle kwesidingo socingo lomhlabathi. Izikhwama ze-Type D zilula ukuzenza kodwa ngokuvamile ziyabiza futhi kufanele zigcinwe zihlanzekile futhi zomile ukuze kugcinwe izakhiwo zazo zokukhipha amandla.

Izikhwama ezinkulu ze-FIBC zisetshenziswa emikhakheni ehlukahlukene ehlanganisa ukukhiqiza amakhemikhali, ukucubungula ukudla, izimayini nezimbiwa, ukwakha, ezolimo, imithi, kanye nokugaywa kabusha. Imboni ngayinye ingadinga izici ezithile zesikhwama ezifana nesitifiketi sokudla esisezingeni, ukumelana nemisebe ye-UV, ama-conductive liners, noma izihlanganisi eziqinisiwe zokuphakamisa kuye ngokuthi yini into kanye nokusetshenziswa kwayo.

Izikhwama ezijwayelekile ze-FIBC ngokuvamile ziklanyelwe ukuthwala izinto eziphakathi kuka-500 kg no-2,000 kg, futhi umthamo ovame kakhulu ngu-1,000 kg (ithani elilodwa). Isikhwama ngasinye simakwe ngokucacile nge-Safe Working Load (SWL) kanye nesici sayo sokuphepha. Izikhwama ezinamandla zingaklanywa ukuze zithwale imithamo emikhulu uma kudingeka.

Izikhwama ze-FIBC zinikeza izinzuzo ezibalulekile zemvelo uma ziqhathaniswa nezinye izinto zokupakisha ezinjengemigqomo noma izikhwama ezincane. Zinciphisa udoti wokupakisha ngetoni ngayinye yezinto eziphathwayo, zithuthukisa ukusebenza kahle kwezokuthutha okwehlisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwentuthu, futhi zenziwe nge-polypropylene evuselelekayo. Abakhiqizi abaningi baphinde banikeze izinhlelo zokuvuselela izikhwama noma zokuzibuyisela.

Bheka izikhwama ze-FIBC eziqinisekisiwe ngokwamazinga omhlaba afana ne-IEC 61340-4-4 yokuphepha kogesi omile, i-ISO 21898 yemigomo ejwayelekile ye-FIBC, kanye nezitifiketi zokuphepha kokudla ezifanele njenge-FDA noma imithetho ye-EU uma uphatha imikhiqizo yokudla. Abakhiqizi abathembekile bahlinzeka ngemiphumela yokuhlola ebhaliwe eqinisekisa ukuhlukaniswa kogesi omile nokusebenza kahle kwemishini.

Ukukhetha uhlobo olufanele lwesikhwama se-FIBC kudinga ukuhlola ukusha nokuvutha kwempahla yakho, ubukhona bezintuli ezivuthayo noma amagesi endaweni yakho, ingqalasizinda yokumisa umhlaba etholakalayo, kanye nesabelomali. Ezintweni ezingavuthi, uhlobo A lwanele. Ezintulini ezomile ezivuthayo, kungadingeka uhlobo B noma C. Ezindaweni eziqhumayo, kunconywa uhlobo C (ngokumisa umhlaba) noma uhlobo D (ngaphandle kokumisa umhlaba).
