Kungani ubukhulu bebin bags bakhangelwa ekuphatha kwemithwalo?

Ukugcina Kwesayensi Ngobukhulu Bebag Nokubukhulu Bekhethe

Ngokubhala kwezinsuku eziningi zokuphatha ukuproducwa kwezibag ethi polyethylene ngemiphakathi yezinkampani zokuproducwa kukaSunho, ngibona ukuthi ubude bawo akuyiyo kuphela inombolo yokuchaza—kuyiyo okugcina ubukhulu bekabag ethi bin ngokuzimisa. Ithimba lethu letekhniki libhekise amathesiti amaningi ekubeni kwezinto ezingaphansi kwezindawo zokubeka izinto ezithile kwezinhlobo zezinto zokuproducwa zikaLDPE, LLDPE, MDPE, ne-HDPE, futhi libonisa ukuthi ubude obalulekile kwe-microns noma kwe-mils buyisilinganiso esibophelela ngokusha kwezinkinga zokuphuma kwezinto ezithile. Isibonelo, ibag ethi kitchen bin enge-15 microns ingaba iyasebenza ngokwanele ngokubeka izinto ezingu-5–8 kilograms zezinto ezingaphansi kwezinhlobo zokusebenza, ngakho ke ibag ethi heavy-duty ethi-30 microns ingaba iyasebenza ngokwanele ngokubeka izinto ezingu-20+ kilograms ngaphandle kokuguqula ubukhulu bakhe. Lokhu akuyiyo kuphela ukungakhathazeki ukuthi izinto zizohlwa; ubude obungafanele bukhuthaza izihluzi ezincinci ezinokuthi zithumele izinye izindlela zokuhlanza nokuthintela izilwane, okuvumela ukuthi ubukhulu be-hygiene bungahlonishwe kwezindawo zokusebenza kanye nezindawo zokuphatha izinto.

Ubukhulu Bekhethi Neubude: Isibindi Sokubili

Abashicileli abaningi bakhumbula okungafanele ukuthi izipakethi zonke eziqinile zihamba ngokufanana, kodwa ubuchwepheshe bomthwalo wethu ubonisa ukuthi isithi sendawo sikhulu kakhulu ekuthinteni indlela okuyisho ukuthi ubude buhambisana nokusebenza. Izipakethi zemibhobho yase-High-Density Polyethylene (HDPE) zingakwazi ukufika emsebenzini omkhulu ngamaphepha amancane kunazo ezinye zase-Low-Density Polyethylene (LDPE) ngoba i-HDPE inenqobo emkhulu yokubamba nezindlela zokuhlanganisa amahlobo. Kwi-Sunho, sizilungise amaphepha okubude ngokwezindlela zokukhetha indawo—sizimemeza amaphepha angu-20–25 microns kuma-HDPE osemabhabhaleni futhi sizimemeza amaphepha angu-30–35 microns kuma-LDPE okusebenzisa kwi-kitchen ukuze kufikelele emsebenzini omfanekayo. Lokhu kubhekisa abakholwa ukusuka kokuqinisa kakhulu (futhi ukulipa kakhulu) izipakethi eziqinile kakhulu noma ukusuka kokuqinisa kancane futhi ukubona ukuthi zihluphe. Utheknoloji lwethu lwesiko-sikho (co-extrusion) lisivumela ukudala izipakethi zemibhobho eziningi izindawo ozinombili okuzimelela umphathi oqinile kakhulu we-HDPE ngezindawo zokugcina ezingaphansi kwe-LDPE, okuvumela ukuthi ubude buhambisane ngokuphelele.

Ukunciphisa Izindlela Zokulungisa Ubude

Ngokusebenzisa ubudlelwane bethu be-OEM namaketanga okupheka kanye nezinsizakalo zemfucuza yasemadolobheni, siye sabhala ukuthi ukukhetha ubukhulu obufanele kuletha ukonga okukhulu esikhathini eside. Izikhwama zemfucuza ezishisa ngokweqile zichitha izinto futhi zandisa izindleko zeyunithi ngayinye ngo-40-60%, kuyilapho ukushuba okunganele kuholela emikhubeni yokugcwalisa kabili empeleni edla ipulasitiki eningi ngokujwayelekile. Sasebenza neklayenti lehhotela elalisuka emasakeni ajwayelekile angu-40 micron laya kumklamo wethu we-HDPE onamakhasi amaningi angu-25 micron, okunciphisa izindleko zonyaka zamabhokisi ngo-$12,000 kuyilapho linciphisa ukusetshenziswa kwepulasitiki ngo-35%. Izinketho zethu zokunemba ezenziwe ngezifiso zivumela ukulinganiswa okunembile kwemithombo ethile yemfucuza izikali ezincane zokuvuselela iphepha, ezomsebenzi ophakathi nendawo zokulahla imfucuza ejwayelekile, nezakhiwo eziqinisiwe zemfucuza yokwakha noma izinto ezicijile.

Umthelela Emvelweni Nokwenza Ngcono Ubukhulu

Ukuhlonipha umhlaba kusukela kubhekisele kwezinkinga zokugcina izindiza ngokupheleleyo. Izindiza ezingaphansi kakhulu, eziningi ukuthi zibe nzima, zimshisa ukusetshenziswa kweplastiki entsha, kodwa kuphela lapho zihlanganisiwe ukuze zingavuleki ngokukhawuleza okungakwazi ukuzibuyisela. Kwa-Sunho, sizibhekisele emithambo yethu yokuhlanganisa i-plastiki ukuze sibone isiphumo esifanele noma kufanele kubeka ubude obuncane ngokusebenzisa i-polymers ezintsha nezinkampani zokuhlanganisa. Isivumelwano sethu se-LLDPE, umzekelo, sibonisa ukuthi kunezindlela zokuvula ezinkulu ngokulingana ngokubili kwe-LDPE, okusiza ukuthi sibuyekele kubude obuncane ngaphandle kokuthi sikhululeka kwezinhlelo zokusebenza. Sibonakalisa abakholwa ukuthi "kuncane akukho kuncane okuncane" — indiza encane eyavulayo kahle kubili kanye kuyenza ukuthi kubhekisele kwezinkinga zokugcina umhlaba kakhulu kunendiza enezubu elincane kodwa enezinhlelo zokusebenza eziphambili. Ukuchaza kwethu kwezinkinga zokugcina umhlaba kusiza abakholwa ukuthi bafunde ubude obuhle okufanele kubekwe kubudlelwano bakho bokuhlonipha umhlaba.

Izinkinga Zokuhlonipha Ukuhamba Nokuphathwa Kwemithambo

Ezempilo, ukudla, kanye nokusetshenziswa kwemfucuza eyingozi, ukushuba kunomthelela oqondile ekuhambisaneni nemithetho kanye nasezinhlelweni zokuphepha. Okuhlangenwe nakho kwethu ekuhlinzekeni izikhungo zezokwelapha kuye kwabonisa ukuthi izikhwama zemithwalo yezinto eziyingozi ngokwemvelo kufanele zihambisane namazinga athile wobukhulu (ngokuvamile okungenani angu-1.25-1.5 mils) ukuvimbela ukubanjwa ngenaliti nokuvuza kuketshezi ngokusho kwemihlahlandlela ye-OSHA ne-CDC Sakha lezi zicelo ezibalulekile ngokukhuthazela okuqhubekayo kokunamathela ku-± 5% okuqinile kunezinga lomkhakha ± 10% ukuqinisekisa ukuthi zonke izikhwama ziyahlangabezana nezidingo zokuqinisekisa. Kumakhasimende ezimboni aphatha imfucuza yensimbi noma ingilazi ebukhali, sikhiqiza izikhwama ezinzima kakhulu ezingama-3-4 mm ezinama-seam aqinisiwe amelana namandla okudlula angaphezu kwama-50 newton. Lezi zincazelo azizizo ezihleliwe; zithathwe kwimininingwane yezigameko kanye nezinhlaka zokulawula ezibeka phambili ukuvikelwa kwabasebenzi.

Ukwenza ngezifiso izinhlelo zokusebenza ezikhethekile

Izikhwama ezivamile ezingekho emashalofini azivamile ukubhekana nezinselele eziyingqayizivele zokusebenza, yingakho izinsizakalo zethu ze-ODM zigcizelela ukwenziwa ngokwezifiso kokunwebeka. Sithuthukise izikhwama eziphansi kakhulu ezingamamayikroni angu-8 ezicacile kakhulu zokuvikela izingubo lapho ukubonakala kubaluleke kakhulu kunamandla, futhi ngokufanayo, izikhwama eziqiniswe ngamamilimitha angu-5 ezenzelwe abaqashi ababhidliza izinto eziphethe izingcezu zikakhonkolo. Inqubo yethu yokubonisana nezobuchwepheshe ihilela ukuhlaziya ukwakheka kwemfucuza, izindlela zokuyilahla, kanye nokuxhumana nayo ukuze kunconywe amaphrofayli anembe kakhudlwana. Kumakhasimende ethu asebenza ngokudla kwasolwandle, sakha izikhwama ezingu-2 mil ezinokumelana nokugqashuka okuphakeme ngokukhethekile kwezigobolondo zama-oyster eziphansi kunezikhwama ezivamile zezimboni kodwa ezenzelwe lelo phrofayela eliqondile lokuqhekeka. Le ndlela eyenziwe ngezifiso iqinisekisa ukuthi amakhasimende awakhokhi ngezinto ezingadingekile noma asengozini yokwehluleka ngenxa yezimfuneko ezinganele.

Isiphetho

Ubukhulu bebin bags kubonakala njengokuphendula okuhambisana nokuziphatha kwe-engineering okuthinta izindleko zokusebenza, ubukhulu bezempilo, isibonelo sesilwane, nokuthanda kwebanki. Kwa-Sunho, ubukhulu bethu ngemithambo yepolyethylene nobukhulu bokusebenzisa ukuthenga kusiza abasebenzi ukuphuma kwezinkinga zokuchaza "buncane noma bude" ukuze bafunde izinkulungwane eziphelele. Uma ungena kubin bags yezindlu, amabhokisi esilwane semaphathi esivumelwe, noma amabhokisi esilwane se-industri ephumelelayo, izinkulungwane zethu zokuchaza ubukhulu kwe-LDPE, LLDPE, MDPE, kanye ne-HDPE ziyathola iziphumo ezibonakalayo. Ukuchaza ubukhulu obuhle akuyiyo kuphela ukuthi silwane siyabhalwa ngaphandle—kuyiyo ukuthi sibophelela izinto ezingcono, sikhululeke abasebenzi, futhi sibhalela izindlela zokusebenza eziphathelene nabantu.
