Kungakwenzeki ukusebenzisa izithelo zokugcina zabalungu ukugcina izinto zokuhlakaza kwendawo?

Izibhakhi zomsebenzisi ziyisigaba esikhulu seziphakamiso zezibhakhi zesilika esiphakeme kumakhethe, kodwa abathengi bafunda ukuthi bakhwela ngokuzimisa ngokuthi ziyasebenza njani ekukhipheni kwesithunzi — futhi ukuthi ukukhipha kwesithunzi kuyinto ephakemayo noma ayikho. Indlela yokuphendula iyiphendula kuspecification yebhakhi, izinhlaka zokukhipha kwesithunzi ezihlakileyo, nokuthi isithunzi sikhulwa njani: kubhakhiwe ukukhipha kwekhasi, kuthunyiselwa kuqondweni lokuhlanganisa amasithunzi, noma kusawiswa kusendlale. Le gujida ibonisa ukuthi izibhakhi zomsebenzisi ziyini, nokuthi izispecification zazo zingahambelana njani nezibhakhi zokukhipha kwesithunzi, futhi ukuthi abaphathi bezimali nabaphathi be- facilities kufanele bakhalise njani kabefore ukuthenga.

Izibhakhi zomsebenzisi ziyini futhi zihlanganiswa njani

Izibhanku zomsebenzisi zihamba ngokuphelele kwe-polyethylene, zabalwe ngokwakhiwa kokuqala ukusebenza ngabasebenzi bokwakha ne-bulldozer abasebenzisa izinto ezilungileyo, ezingavamileyo njengokukhanyekile kwe-drywall, izibhanku zomthi, izinyathelo zebhlokli, nezinkambo zemetalu. Izindlela zokubalwa kwazo zihlukaniswe ngokuthi zinomthubi wokubalwa okuphelele — okuvamile kubili 2.5 uye ku-3.0+ mil — nokubalwa kwezindlela okuzosiza ukubaleka izilwanyana ezivamile kusukela ku-50 uye ku-100+ lbs ngaphandle kokugqibela komkhono. Zibalwa kakhulu ngombala ongumnyama, noma zinomkhawulo wesikhundla esivamile kusukela ku-42 uye ku-55 gallons, futhi zinomkhawulo wendlela yokuqala okuhambisana nesikhundla (star-seal) noma yendlela yokubalwa yendlela yokuqala (flat-seal).

Ibhalayisi esikhulu sebagi yomsebenzi yasemthwakweni isithunywa kakhulu ukukhathazeka kwezinto ezilungile ngokuphambana nezinto ezingenakho ukuthi zibhaleke, kodwa akasithunywa ukuthi sifanele kakhulu ukusuka kwezinye izinto. Ibagi zonke zomsebenzi zasekhasini zisetha i-linear low-density polyethylene (LLDPE) noma i-blended PE resin okuyindlela yokubaluleka kokh strength nokuphela kwezinye izinto, okuvumela ukuthi ibagi libe lisebenza ngokwamanje kwezinto ezingenakho ukuthi zibhaleke futhi kwezinye izinto ezingenakho ukuthi zibhaleke ngokushesha. Lokhu kubalulekile kakhulu ukusebenza kwezinto zokugcina emhlabeni — umbuzo uyisiphi: ukuthi iziqephu zabo zihlakaniphiwe ngokuphelele ukusebenza kulesi sikhundla, noma ukuthi ibagi elincani ukuthenga emhlabeni liyasebenza ngokufanayo kulesi sikhundla.

Izinkulungwane zezinto zokugcina emhlabeni nezinto ozikufuna ukuthi zibe ngokwesibageli

Izinto ezihlukene kweyini ziyizinto ezenziwe ngumkhakha: izinye zokuphakamisa, izinye zokubhala, izinye zokubhala, izinye zokubhala, isolo, nezinto zokubhala. Zazingakwazi ukuthi zifake izinto ezingavamile, ezingasemthethweni, ezinokuvula izinye zokubhala. Kepha, izinto ezihlukene kweyini ziyakha izinkinga zokuload: zingakwazi ukuba zibhebhe nezinkulu, izinye zokubhala nezinye zokubhala zingakwazi ukuthi zibe nesikhathi sokubhala, futhi izilayishu zokubhala zingakwazi ukuthi zibe phakade kakhulu kuma-30 ukuze kube kuma-50+ lbs.

Ibagi yezinto ezihlukene kweyini engekhethekileyo eyisikhathi esinye kanye ne-2.0 mil iyasebenza kahle kuzo zonke izilayishu zokusebenza kwezindlu. Uma kufuneka ukusebenzisa izilayishu ezinkulu zokusebenza kwezindlu — izilayishu ezinkulu zokubhala okubhebhe, isolo esinkulu, noma izinye zokubhala ezinkulu — ibagi yezindlu engekhethekileyo eyi-2.5 mil noma kude kwalokho kuyathatha isikhathi sokubhala ngokuphakeme kakhulu uma kufuneka ukubhala noma ukuthintela. Iqondo lokubhala lwe-bagi yezindlu elithuthukileyo nezinye zokubhala ziyakwazi ukuthi ziyathinta ngokuphakeme uma ibagi ibhala kusuka kwe-pavement, ibhala ngamaphakade, noma ibhala kusuka kwe-collecting vehicle.

Kubathengisi abaqinisa ukugqina kwezinto ezithile, umbuzo ongempilweni awungummbuzo wokuthi "izipakhi zezindawo zokusebenza zingakhuluma ngokwesithembiso sasezindaweni" (zingakhuluma), kodwa umbuzo ongempilweni wokuthi "ukusebenza kwesithembiso sasezindaweni kufuneka ukugqina kwezindawo zokusebenza, noma izipakhi ezingenani kakhulu zingafanele?"

Izidingo Zokuphatha Ngokwemithombo: Ukugqina Kwezindawo Zokusebenza Nokuthenga Kwesikhathi Sokuthenga

Umphumela wokusebenza okunzima okuhambisana nezisekelo zokusebenza kwezindawo zokusebenza kanye nezisekelo zokuthenga kwezindawo zokusebenza kuyi-ncike esikhundleni sokuthenga kwesikhathi sokuthenga. Iziphakamiso eziningi zokusebenza kwezindawo zokusebenza kanye nezisekelo zokuthenga kwezindawo zokusebenza ziqinisa noma zihambisana nokuthenga kwezindawo zokusebenza kwezindawo zokusebenza. Izinhlangano eziningi ziqinisa izipakhi zebhukhisi noma izipakhi zepolimere eziyisifundo sokuthenga kunezipakhi zepolietileni ezingenani — ngoba izipakhi zepolietileni ezingenani, futhi izipakhi zezindawo zokusebenza, azikwazi ukuthenga kwezindawo zokusebenza kanye noma ziyakwakha isibindi sokuthenga uma akasuswali.

Kumaqondiswano okwenziwa emhlabeni okuthathwa ngayo imibhakiso yebhilekhi, kunezinkinga zokugcina ukusebenzisa imibhakiso yezinkambo kumithombo yemithi noma kuyinto ekhoyo njengoba imibhakiso iyakwenzeka ngokuphelele kwezinkinga zomkhondo noma kwezinhlobo zokusebenza kwesikhundla. Kodwa, kumaqondiswano okuthatha izibhakiso zokufaka emthombweni, imibhakiso yezinkambo — noma yikuphi umsebenzi wakho — ayizukwamukelwa. Abaqondi bokuthenga imibhakiso yemithi yokuzilungisa izindawo ezithunywa kumithombo yokuqondisa emhlabeni kufanele bavumile izinkinga zokusebenza kwezindawo zokusebenza phambi kokuvumela ukusebenzisa imibhakiso yezinkambo.

Kwesikhundla sokuzilungisa imithi — ukusonga, ukuthumela ku-‘skip’, noma ukugcina kucacile phambi kokuthunywa — imibhakiso yezinkambo yisikhundla esihle nasezinkundleni eziningi, futhi izinkinga zokubaluleka zazinye zingasenzi kakhulu.

Isibonelo Sesikhundla: Umthengisi wezintaba ozilungisa ukubona izibhakiso zokusebenza

Qaphela inkampani yokuqondisa amasango enkampani eyasebenza ngamabhasi amabili: amakhontrakti wokuphatha amasango okuzilwa nokuphatha amasango amakhulu okuzilwa kwezindawo zokusebenza. Kukhona umsebenzi wokususa izinyoni nezinyoni zokuphatha izilwane kumasango, abantu basebenza ngamabhasi ayisigaba esihlukene sokubhala amasango okuzilwa aye-1.5 mil LDPE — okuyisifanekile kumandla okuthile okunikezwa kanye nesifundiswa sokuthengiselwa kumkhulu okuthile okuthengiselwa.

Kubaprojekthi bakomeshini lapho kubalwa ukukhishwa kwemilitha enkulu yemulch eshushu, amaphakathi emisolo, namaswidi okuphuma kwezinye zezindawo zokuthatha isikhundla sokubuyisa izindawo zokufaka imithombo, umntwana wabuye wasebenzisa iibhagi zesi-3.0 mil zokusebenza ngokwezinkambo. Umthwalo wokuvakashela akwaba yindlela yokubhala ubhaghi kodwa izimo zokusebenzisa: ibhagi zidlulwa phezulu kwesandla, zihlanywa futhi zifakwa emshini, futhi ngamanye amazwi zingakhohlwa ezingeni lapho ziyakwenzeka ngokugcina kwezindawo ngomso kusukela kwezindawo zokuthatha isikhundla sokubuyisa izindawo zokufaka imithombo. Kulezi zimo, ibhagi yesi-1.5 mil ayisabalise kuzinzinzi zokubhala nokuphakamisa ngokungafanelekile. Ukuguqula kubhagi yezinkambo zokusebenza yasimela ukubhala kweziprojekthi zakomeshini futhi yasusa umthwalo wesibili wokubhala kabili noma ukubuyisa ibhagi elizwele kuzindawo.

Ukuphulukana kocost ngendawo yomqolo wabuyiselwe ngokukhishwa kwemiphumela nokusebenza okusavunyelwe ngokungakwazi ukubeka kabusha amaqolo aqhutshelwe. Lokhu okufanayo kokuchaza isibalo sokucost kuyinto esebenzisa umkhondo wokugcina okwenziwa ngabasebenzi bokuthenga izintlu, kodwa akayi ukuziqhula ngokuzimela ukusebenzisa umqolo omkhulu kakhulu wonke ngokwesikhathi.

Kini okufanele ukubonakalisa xa kuthengiswa izinqolo zabadala bakhiya kusuka kumaqondo

Kumaqondiswano okanye amaphoyisa okwenza izinye zezinto ezikhanyayo, uma kusetha izibhaghi zamaqondiswano ngokukhulu, izindlela zokuphatha zokuvumela ziyashiyekile: ubude obubonisiwe ngamili (akayi nje isibonelo sokuthi ‘sikhe’), ubukhulu bokuload ngama-pounds, uhlobo lwesikhumba (isikhumba sesistari sithandwa kakhulu kumaqondiswano amakhulu nezinhlekehleke), nokuvumela ukuthi kubhekwe i-UV uma izibhaghi zizokugcinwa ngaphandle emshini phambi kokuthunywa. Umbala uyisibonelo sokusebenza: izibhaghi zamaqondiswano ezingomnyama zinakha umkhawulo wokubhekwa kwe-UV kumaqondiswano, futhi ziyisibonelo esihlukene kumarket yaseNorth America, ngakholo izibhaghi eziningi zingahitshwa kuzo iziprojekthi zokuvula okanye ukujabula.

Kubathengisi abathenga ku-mafabrikhethi emasweni amaningi, izindikimini zokuvumela kuka-REACH ne-RoHS zibonisa ukuthi izinkambo zefilimu ziyagcina imithombo yezinhlelo zokuphepha kwemikhono yezinhlelo zokuphepha — lokhu kuyisikhundla esihambisana ngezibalo zokuphepha eziphakathi kwezinye izinto ezinokuthi zibe nendawo yokuxhumana ngokuphakade ngezinkambo zokuphepha. Ukuvumela kuka-ISO 9001:2015 kubonisa ukuthi ubukhulu bekuphepha kubalulekile kuzo zonke izikhathi zokuphepha, okunika ubuncinane bezinkinga zokuguqula kwezinkambo zokuphepha nezinkambo zokugqibela.

SUNHO Packing (i-Guangdong Sanhe Packaging Products Co., Ltd.) iyaphrodukha izihlakulo zesayensi ezinikezwe ngokuphathelene nezinhloso zezibargo ezingenabizo, ngenkulu yazo yisikhathi esinye kanye nezinhloso zokusebenza kwe-2.5–3.0+ mil ngezindlela zokugcina emuva nesikhundla sokuload up to 100+ lbs. Ukuthenga ngqo kwisifactory kusukela ku-mfr yomthwala wokuphatha okubonakalayo (2 million units per day) nokuthi kunezicertifiketi zokuhle (ISO 9001:2015, REACH, RoHS) kungakhula ukholwa kwe-unit ngokuphakeme kwe-20–40% kunokuthengiswa kwe-distributor — lokhu kuyinto ebalulekile kuma-landscaping companies noma amafasiliti ene-ongoing consumption ephakeme yezihlakulo zesayensi.

Imibuzo Evame Ukubuzwa

U: Izihlakulo zesayensi ziyasebenza kwezinhloso zokufaka emuva kwezihlakulo sezinkunkuma?

A: Iimbhakela yezinkokhelo zasezulwini zokusebenza kwe-polyethylene, ezifana ne-LDPE ne-HDPE, aziyikompostiwa futhi aziyavumelwa emikhakheni yokukompostisa okuyisifunda sokukompostiswa okuchazwe noma iimbhakela zepaperi. Uma isivumelwano sakho sokuphatha izinto ezingasizi kufune iimbhakela zokukompostiswa ukusuka kwezinyawo, kufanele uthole iimbhakela okuchazwe ngokukompostiswa kanye nokungatholakali iimbhakela zokusebenza kwezinkokhelo. Kukuphatha kwakho kwenkathi noma kumaqembu okuvumela iimbhakela zokusebenza kwezinkokhelo, iimbhakela zokusebenza kwezinkokhelo ziyasebenza ngokuphelele.

U: Ithikinesi yombhakelo wokusebenza yini oyidingekayo ukusuka kwezinkinga zokubeka izinto ezingasizi?

A: Kukhona ukuthi kubalulekile ukusebenzisa izibaguli zomthwakazi wezokuphatha amasiko, izihlalo zemithi, nokuthabatha amaphakathi wesihlalo noma amaphakathi esikhumba, ngokwezindlela zokusebenzisa ezinkulu, uma ubuyisela up to 50–70 lbs, isibaguli sokumthwakazi esinamandla okusuka ku-2.5 ku-3.0 mil nesifunda sesihlalo sesihlalo (star-seal). Uma ubuyisela phezu kuka-70 lbs noma kusetyenziswa kuzo izimo eziphambili kakhulu (ukudraga kusuka kwe-gravel noma kwezinye izinyathelo eziningi), isibaguli sokumthwakazi esinamandla okusuka ku-3.0 mil noma phezu kwalokho sibonakaliswe njengokuthi kuyisibaguli esibalulekile. Uma ushiyela i-inquiry yokufaka imali, qiniseka ukuthi umkhakha wokuthi kuyisibaguli sokumthwakazi kanye nesifunda sesihlalo (seal type) kusuka kusilungisi.

U: Ngikwenzela ukusebenzisa izibaguli zomthwakazi ukuthabatha izinto ezinokuthunyelwa futhi noma izinto zokusebenzisa ngokujulile ngokwenziwa ngokwesikhumba?

A: Iziqiniso zokusebenzisa izibaghi zasemthethweni azisilungile kusenzo esithile — ukubekwa kwazo kwezinkambo ezingcono kakhulu kuzokwenzela ukuthi ziyasebenza ngokuphelele kuzo zonke izinqumo zezinto ezizwakalayo, okufana nezinto zokuguqula, ukucima kwesayensi, nokuzwakala kwezinto zokuzwakala ngokuphelele. Isidingo esisodwa sokumelwa kuyilo lokho ukuthi inkambo yakho yezinto ezizwakalayo yasemthethweni iyathatha isidingo esithile kuzo izibaghi ezisebenziswayo kuzo zonke izinto ezizwakalayo eziphakathi kwesikhumba. Kuzo zonke izinto ezizwakalayo ezingcwalwa ngokuprivati (izibaghi, izindawo zokuhambisa, ukugcina kusendaweni), akukho zimfihlo zokusebenzisa izibaghi.
