Izithelo zokugcina ezinamandla amaningi kunye nezithelo zokugcina ezingamandla angaphezulu zihlukene njani

Kusukela kubagqambezeli bekuphatha, abasebenzisi bekudala, nabathengi bekuphakamisa, ukukhetha phakathi kwezibaguli zokuthenga eziningi nezibaguli zokuthenga ezingaphansi kukuchaza okukhomba ukusebenza nokuthabatha izinto zokuthenga zonke. Lezi zimithi ziyabonakala kuzonke iziqephu zesikhundla sokuphatha, kodwa ubuchwepheshe bezomthombo wokuthenga — nokuthi lezi zindlela zokusebenza zikakhuluma ngokwesibonelo esihlukene — ziyasemiswe kahle. Le ndlela yokuqonda iqhaza eliphelele phakathi kwezibaguli zokuthenga ze-HDPE nezibaguli zokuthenga ze-LDPE, ukuthi le qhaza iyakhombisa njani ukusebenza kwempilo, nokuthi iziqephu zizifane njani ngezinye izinto zokuthenga abagqambezeli baya kuzilungiselela ngaphambi kokuthenga kwezinkambo.

Ubuchwepheshe Bekomthombo Wokuthenga We-HDPE Ne-LDPE

I-polyethylene ephakamile (HDPE) ne-polyethylene engezansi (LDPE) zonke izipolimha zezithakelwa ezinokuthakelwa kwe-ethylene, kodwa izithakelwa zabo zihlukana ngendlela esebenzisa kona izinto zokubaluleka zokugcina. I-HDPE inenqubo yomthwalo olinelayi kunye nokuphakanyiswa kakhulu, okubangela ukuthi ibe yinkulungwane engcono, inkulungwane engekhulu kakhulu noma yisiphakade sakho, nokuthakelwa okukhulu kakhulu kokuphakamisa. I-LDPE inenqubo yomthwalo eyahlukene, okubangela ukuthi ibe yinkulungwane engekhulu kakhulu, inkulungwane engekhulu kakhulu noma yisiphakade sakho, nokuthakelwa okukhulu kakhulu kokuphakamisa kabusha.

Kuziphakathi zokusebenzisa okwanele: Iibhagi ze-HDPE ziyisahluko kancane kwaye ziyizimnyama, nekhanda lokugqogqo xa zisebenziswa, kwaye zixhaphakile kakhulu ukusuka kwezinto ezingenziwe ngamandla njengoko ubude bakho bawubonisa kuphela. Iibhagi ze-LDPE zingabonakala zinomthelela kancane kwaye zinomthelela kakhulu, zinomthelela kakhulu kwiizinto ezingafanayo nezinto zokugcina, kwaye zinokuthabatha umphumela kanye nokunyusa ngokuchitha izinto ezingenziwe ngamandla ngokungathinti kancane njengoko zilungile. Izinto zombini zinokuprodukwa kusuka kwezinto ezintsha okanye kusuka kwezinto eziphathelene nazo ezisemthwakweni, kwaye zinokutholakala ngokufana nezinto zokugcina, nezinto zokugcina ngokufana, okanye nezinto zokugcina ngokukhanya.

Izilinganiso zokusebenza: Lapho umbhalo wokusebenza unguquka

Kwimfuyo yasekhaya nezinkambo zokusebenza ezingenayo ubukhulu obukhulu, apho umthwalo uyisiphephelo, izinto ezincinci, nezinto ezingenakwazi ukuthabatha isibindi, izilayini ze-HDPE kwi-6–13 micron (noma ngokuphakanyiswa kwe-0.5–0.7 mil) zisebenza kahle futhi zingaba yinkosikazi. Ukuthi kunezinhlobo eziningi zezinye zokubhala kuzo kusuka kumkhumbi wokubhala kuyenza ukuthi umkhumbi uqukethe izibaghi ezingaphezulu kuma-LDPE okufanayo ngomkhumbi wokubhala, okunika ubukhulu obungaphezulu bokubhala kanye nokugcina izindawo zokugcina.

Kukhuluma ngamabagasi e-kitchen, ukusebenzisa izinkonzo zokudla, ukubeka isibonelo sezindlu, noma izindlela ezihlanganisa izinto ezinamaphakade amabi njengezincwadi zeglashe, izinkundla zemetalu, noma izinkundla zokubanga, izibagasi ze-LDPE ziyachoseni kahle. Izisombululo zesibagasi se-LDPE zisiza ukuthi isifilm sithathe isikhathi sokunquma emanzini yokuqondana ngaphandle kokuphatha, okuyisibonelo sokuthi kusenza kahle kulezi ziqondi zokuphatha kwezinqumo zokuphatha kwezinhlobo ezahlukene. Kukusebenzisa izinkonzo zokudla nezinkonzo zezindlu, izibagasi ze-LDPE ezinilinganiswe ngemil 1.0 noma kude kuyisiphumo esisodwa ngoba ukuthi izinhlobo eziningi zokuphatha nokuthi kungafanele kuzenzekile kwezinye izinto kuyakhula kakhulu kunezinkinga zokuthi kuyingaphezulu kwezinye izibagasi ze-HDPE.

Ubukhulu nobukhulu bokuphatha: Ukufunda izisombululo ngokwesibonelo

Kunye kwezinkinga zokufunda eziphakathi kakhulu xa kubhekana izihlambi ze-HDPE ne-LDPE kukuba kubhekana ubude be-mil njengokulinganisa ngqo phakathi kwezinhlobo zomfanekiso. Ngoba i-HDPE ina-tenacity ephezulu, isihlambi se-0.5 mil se-HDPE singathwala umsindo olinganayo nesihlambi se-1.0 mil se-LDPE kwezinhlobo eziningi zezinto ezingasendlini. Ukubhekana kuphela ubude obazwakalwa ngaphandle kokubhekana nenhlolo yomfanekiso kusenza ukuthi sibuye sifuna izihlambi ze-LDPE ngokuphakeme kwezinhlobo ezingahambani ne-HDPE, noma sibuyisela isihlambi se-HDPE ngokungafanele kwezinhlobo ezingadinga ukuthinteka kwe-LDPE.

Amathimba okufunda kufanele abeke amaphethini okuthwala umsindo ngama-pounds ngokwesibonelo sokubude, futhi abeke ukuthi isihlambi sisizwe ngokwesibonelo esikhulukile. Kuma-buyers asebenza ngokwesibonelo esikhulu, kuhlanganise ukubeka amadokhumenti yokuthi umfanekiso wakhiwe ngokuphatha kanye noma ungenwe kuleliqiniso, ngoba lokhu kuthinta ukulinganisa phakathi kwezibalo — ikakhulu kwezihlambi ezidinga ukuthi zibezelela ku-zincinga zokudla noma zibezelela ku-zincinga zezindawo zokugcina izinto zokusebenza kwezinkambo.

Izithi zokuvulula nokuthinteka kwemisebenzi

Zombili izikhwama ze-HDPE ne-LDPE zitholakala phezulu, phezulu kwamagagasi (okubizwa nangokuthi uphawu lwenkanyezi noma phansi kwenkanyezi), kanye nokuhlelwa kwe-drawstring. Ukukhethwa kokuvala kuhlangana nohlobo lwezinto ezibonakalayo ukuze kuthinte ukusebenza kahle nokusebenza kahle komsebenzi.

Izikhwama ezinezitezi ezivulekile zinezitezi ezivulekile ezingavaliwe; ziyindlela eyonga kakhulu futhi ziyisisekelo sezikhwama ezincane. Izikhwama eziphezulu noma ezihlanganisiwe zinokuhlunga phansi okwenziwe ngokugoqa nokuvala isisekelo ngesimo senkanyezi, esakaza ukucindezelwa komthwalo ngokulinganayo kunokuhlunga phansi okuphansi futhi kunciphise ubungozi bokwehluleka kokuhlunga ngaphansi kwemithwalo emikhulu noma engajwayelekile lokhu kwakhiwa kubalulekile ikakhulukazi Izikhwama ezinezintambo zokudonsa zengeza indlela yokuvala eyakhelwe phezulu esikhwameni, evumela ukuvalwa ngesandla esisodwa nokuthwalwa; ziyisisekelo ezindlini zabathengi futhi zisetshenziswa kakhulu ezindaweni zokuhweba lapho isivinini sesikhwama sokubopha sibalulekile ekuhambeni komsebenzi.

Kubuyeri abathenga ngokukhulu, ukuziqonda isitha sokugcina ngokujabulisana nezinto zokwenza nokubhindeka kusiza ukuthi izinkampani zibe nesibonelo esifanayo.

Isibonelo Sesicelo: Ukuchaza Izisifundo Zokugcina Ngokuphinda Kabusha Kwezindawo Eziningi

Hlola indawo yezinkampani ephatha izindawo eziningi eziqondile ngokufanayo, okuyizindawo eziphatha izindawo zokusebenza, indawo yokudla, nokuthenga izinkampani zokuphatha indawo. Isigaba sokuthenga sasemva sasenziwa ngokuphinda kabusha isifundo sesiliner se-LDPE esifanayo kuzo zonke izindawo ezithathu. Emva kokuchazwa kwezindlela zokusebenzisa, bafindile ukuthi izindawo zokusebenza zasezindaweni zisethula izibaguli eziphelele ezisetyenziswa kwindawo yokudla — lokhu kuyisimo sokuthengiselwa kakhulu, ngoba izinto ezingavaliyo zokusebenza kuzo zingadingi izinkinga zokubhindeka zika-LDPE.

Ngokugcina izindawo zokusebenza ngamaphepha e-HDPE esebenzisa isibonelo sokuphakanyisa isikhundla sokubeka amaphepha e-LDPE okwesikhaleni nasekhaya, umsitha waphula imali yokubeka amaphepha kuzindawo zokusebenza ngaphandle kokugcina iziphakamiso ezifanele kuzo kuphela lapho kufuneka ukuthi kubekwe ukuthi kungabi nesiphambano nokuthi kubekwe ukuthi kungabi nesibhakabhaka. Ukugcina okwakwenziwa kuyadinga ukuchazela ukuthi kubekwe ukuthi kungabi nesiphambano, ubude bokuphakanyisa, nokukhala kwesigaba sokubeka ngokujikeleza — akukho mlando wokubhala ngomthwalo wokuqondwa. Abasendisi abathumela izincwadi zokuchaza izinto ezifana nehlobo lematerial, ubude be-micron/mil, nokukhala kwesigaba sokubeka kuzoba yinkimbinkimbi yokuchaza lokhu kubasethambo sokubhala.

Kini Okufanele Ukuchazwa Lapho Kukhethwa Amaphetha E-HDPE Nase-LDPE

Kubasebenzisi ababuyi abasebenzisa izinkambo nezinkambo zokusebenza, ukuzilungiselela kwezithuthi kufuneka kufakelwe ukuphawula kwesithuthi (sokwesibonelo noma sokwesibonelo esisuswa), ubukhulu obuhambisana ngokuphelele kwezindlela zokuproducwa, nokuthi kufanele kubhalwe indlela yokubhala isikhumba. Imifanekiso yomthwalo noma ukubhala (kubonekwa ku-8-color printing kunezindlela eziningi) kungafanele kubalulekile ekwahlukaneni kwemithwalo ekupheleni kokususa imithwalo noma emizinhleleni yokuqinisekisa ukuthi izinto ziyasuswa. Ukuthi isithuthi siphathwe ngokwesiqephu se-ISO 9001:2015 nokuthi sifanele ngokwesiqephu se-REACH nase-RoHS kubonisa ukuthi isithuthi sithabatha inkambo yezinto ezenziwe ngazo — lokho kubalulekile uma iziphasi ziyakhubazisa imithwalo yomshado, izinto zokuzinikela, noma ziyasebenzisa emizinhleleni eneziphiwo zokuthi izinto ziyafanele.

SUNHO Packing (i-Guangdong Sanhe Packaging Products Co., Ltd.) iyaprodukha izipakhi zezinyama zokuphatha izinto ezilungile nezilungile kakhulu, ngezindlela zokuphatha ezihlukene: ngokwesikhundla sokuphatha esibomvu, ngokwesikhundla sokuphatha esisemaphetheni, futhi ngokwesikhundla sokuphatha ngokuzithabathisa. Bayisebenzisa izinkambo ezingenakho futhi ezingenakho okuyizinkambo ezingenakho. Ukuprodukha kwabo kusayinisiwe ngokwesifundo se-ISO 9001:2015 futhi kufanele kubhekwe ukuthi kufanele kwe-REACH futhi kwe-RoHS. Uma kubhekwa abasenduli bokuthenga, ukunqoba isampula esinezinkambo ezimbili ngokuthi kubonakaliswe ubude bekhanda futhi ubukhulu bekho bokuphatha kungaba yindlela yokubona ngokwesibonelo ukuthi kufanele kwezinkinga zakho phambi kokuthenga ngokukhulu.

Imibuzo Evame Ukubuzwa

U: Ngikwenzela i-HDPE trash bags ukuphatha izinto ezilungile kwekitchen?

A: I-bhagi ze-HDPE ziyakwenzeka kwezinto ezingenani ezinamandla emkhumbi wokukhala okungakhulisi izinyawo, izinkamba ezingavunywa, noma izinto ezingenakho isibonelo sokuphuma. Kukhona izindlela zokusebenza zezindlu zokukhala noma izindlu zokusebenza eziphezulu apho izilimi zingaphezulu kanye nezinhlobo zemithi ezingenakho amanzi, i-bhagi ze-LDPE eziqinisekisiwe ngemil 1.0 noma ngaphezulu ziyisikhundla esihle kanye nesikhundla esinamandla kakhulu. I-bhagi ze-HDPE ziyakwenzeka ukuthi zizwele ngokusha kakhulu phakathi kokuphuma kwamanzi nokubuka kwezilimi ezingenakho isibonelo sokuphuma okuyisibonelo sezinto zokukhala.

U: Kungani i-bhagi ze-HDPE ziyathetha ukuthi zingaphansi kodwa ziyakwenzeka ukuthi zilinda ngokujabula njengesi-bhagi ze-LDPE?

A: Isimo esiphambili sekhombe le-HDPE sisona ukuthi sibe namandla okukhanya ngomkhombo wokugcina ngokuphansi kakhulu kungezinye zezinyathelo zokugcina zesi-LDPE. Lokhu kusho ukuthi i-film engephansi ye-HDPE iyakwenzeka ukuthi ibe yilinde ngokujabula njengesi-film esiphansi kakhulu se-LDPE kumasebenzi okungakhiywe amanzi noma okungakhiywe izilimi ezinamandla. Ukuchaza kuyakwenzeka ngokuvutha noma ngokubuka kwezilimi ezingenakho isibonelo sokuphuma, apho izindlela zokuzweleka zesi-LDPE ziyakwenzeka ukuthi zibe yilinde ngokuphelele.

U: Kungani 'star seal' noma 'wave top' kusetyu yesipekhi yebhagi yezinto ezinamandla?

A: Isilayishi sesitha (okusho kakhulu ngokuthi isitha sesihlathi noma isitha sesinye) sibhekisela kuqondiso lokugcina kwesandla. Ngaphandle kokugcina okuphelele kusandla sobheshi, isilayishi sesitha sifakwa ngokufaka isandla ngamadirection amaningi futhi ukugcina kufakwa kusinye. Lokhu kuhambisana umthelela wokubheshisa kobheshi kumapoint amaningi okugcina ngaphandle kokukhanya kumsebenzi omunye wokugcina, okungakhathaliseki umphumela wokugcina wesandla phansi phakathi kwezinkinga ezinkulu noma ezingavamile.
