Ulwazi

Kwi-extrusion Blow Molding (EBM), ipulasitiki iyancibilika futhi ifakwe kwishubhu eliyimbumba (parison). Le parison iyabanjwa ngokuyivala ifakwe kwisikhunta sensimbi esetshenzisiwe. Umoya ube usushayelwa ephalishi, uwukhuphule ekwakheni ibhodlela eliyize, isitsha, noma ingxenye. Ngemuva kokuthi upulasitiki usupholile ngokwanele, isikhunta siyavulwa bese kuthi ingxenye leyo ikhutshwe.

Ukubuyisa izixazululo zokupakisha - Amashidi epulasitiki e-Flat Kuyo yonke le minyaka, siye sakha ndawonye nabalingani bethu izixazululo ezihlukile zokupakisha zamakhasimende ethu, ikakhulukazi sigxile kuzixazululo ezinokubuyiswa zokupakisha ngoba ezimweni eziningi zinembuyiselo ephezulu yokutshala imali. Esokuqala esixoxa ngaso kulesi sihloko sithi 'Returnable plastiki flat

I-GOST (isiRashiya: i-ГОСТ) isho isethi yamazinga wezobuchwepheshe agcinwe nguMkhandlu wase-Euro-Asia wokumisa, Metrology and Certification (i-EASC), inhlangano yamazinga wesifunda esebenza ngaphansi kokuphakanyiswa kweCommonwealth of Independent States (CIS).

I-high-density polyethylene (HDPE) noma i-polyethylene high-density (PEHD) iyi-polyethylene thermoplastic eyenziwe ngophethiloli. Ngezinye izikhathi ibizwa nge- “alkathene” noma i- “polythene” uma isetshenziselwa amapayipi. Ngesilinganiso esiphakeme samandla kuya kokuminyana, i-HDPE isetshenziswa ekukhiqizeni amabhodlela epulasitiki, amapayipi amelana nokugqwala, ama-geomembranes, namapulangwe. I-HDPE ivame ukusetshenziswa kabusha, futhi inenombolo engu- “2” njengekhodi yayo yokuhlonza i-resin (eyayaziwa ngaphambili njengophawu lokurisayikilisha).

Ukuqanjwa komugqa ongafanele kubaluleke kakhulu uma umugqa osebenza kahle uthandwa. Le ndatshana imayelana nomugqa we-PET wokugunda wejubane eliphezulu, umthakathi wenzelwe ngale ndlela. Sizoxoxa ngencazelo ye-OEE nezincazelo ezisebenzayo, izinzuzo zokubheja kanye, nokuqina kwepallet, okokugcina kodwa hhayi okungenani ngomqondo wolayini ngokuningiliziwe.

Uma ufuna ihotela ngesikhathi sakho sokuhlala @ Delta Engineering, uhlu lwamahhotela athile amahle

Inqubo yokujova inaliti blowing (IBM) isetshenziselwa ukwenziwa kwengilazi engenalutho nezinto zepulasitiki ngamanani amakhulu. Ngenqubo ye-IBM, i-polymer ifakwa umjovo wepiyili oyisisekelo; lapho-ke iphini lomgogodla ligijinyiselwa esiteshini sokubumba esinamapayipi ukuze lishiswe futhi lipholisiswe. Lokhu kusetshenziswa okungatheni kulezi zinqubo ezintathu zokubumba ukushaya, futhi kuvame ukusetshenziselwa ukwenza amabhodlela amancane ezokwelapha nawodwa. Inqubo ihlukaniswe ngezinyathelo ezintathu: umjovo, ukushaya kanye ne-ejection.

Amakhadi Wokuphepha Kwamakhemikhali Womhlaba wonke (i-ICSC) ngamashidi edatha ahlose ukuhlinzeka ngemininingwane ebalulekile yezokuphepha neyempilo kumakhemikhali ngendlela ecacile necacile. Inhloso eyinhloko yamaKhadi ukukhuthaza ukusetshenziswa ngokuphepha kwamakhemikhali emsebenzini futhi abasebenzisi abaphambili okuhlongozwayo ngakho-ke bayizisebenzi nalabo ababhekele ezokuphepha nempilo emsebenzini. Iphrojekthi ye-ICSC ingumbambiswano ohlanganyelwe phakathi kweWorld Health Organisation (WHO) kanye ne-International Labour Organisation (ILO) ngokubambisana ne-European Commission (EC). Le projekthi yaqala ngawo-1980s ngenhloso yokuqamba umkhiqizo wokusabalalisa ulwazi oluyingozi lwamakhemikhali endaweni yokusebenza ngendlela eqondakalayo nenembayo.
