Izinqambu eziphikisana nezinto eziyizindlela zokuphikisa izibaghi zokugcina izinto ezihlukile?

Kweminyaka yokuqondisa izinto ezihlukene, ubunzima bezobugcwebo bokubhala kuyisibonelo esisodwa sokuvikela umhlaba nesikhundla sokusebenza. Iimbhakhi zokugcina izinto ezihlukene ezingenakuphula ziyizindlela zokugcina eziqinileyo zokuthi zitholele amandla okusebenza okuqinileyo wezinto eziphakathi, nezinto ezingenakuphula, nezinto ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenakuphula okanye ezingenak......

Indima Yezinkampani Zokusebenza Kakhulu Kwizibonelo Zokuphula

Isisekelo sanoma isiphi isembozo sokulwa nokushaywa silele ekwakhekeni kwaso okungama-molecule. Ngokungafani nezikhwama ezivamile, izikhwama zemfucuza ezisezingeni elifanele zenziwa kusetshenziswa ingxube ye-Linear Low-Density Polyethylene (LLDPE) ne-High-Density Polyethylene (HDPE). I-LLDPE ibaluleke kakhulu enqubweni yokukhiqiza ngenxa yokuqina kwayo okuvelele kokuqina kanye nezakhiwo zayo "zokunwebeka lapho kuphuka". Lokhu kusho ukuthi lapho into ebukhali njengengengengxenyana yensimbi noma ingilazi ephukile icindezela phezu kobuso, ifilimu iyelula futhi iphenduke umbala nxazonke zento kunokuba ivumele ukuphuma. Le "memori eguquguqukayo" iyisici esibalulekile kunoma isiphi isakhiwo esibhekana nemithombo yemfucuza engafani, inikeza isithiyo esithembekile esigcina isimo sayo somzimba ngaphansi kokucindezelwa.

Ubuchwepheshe Bokukhishwa Kwezinga Elikhulu Lokukhishwa Kwezinga Elikhulu Lokukhishwa Kwezinga Elikhulu Lokukhishwa Kwezakhiwo

Ulwazi olusezingeni eliphezulu ekukhiqizeni izinto zokwenziwa zanamuhla eziyinsimbi eziyinsimbi luholele ekwakhiweni kwamafilimu ahlanganisiwe, anikeza ukuvikelwa okuphezulu kakhulu kunezindlela zokwenza izinto eziyinsimbi eyodwa. Ngokwenza "isandwich" yezindlela ezihlukahlukene zokwenza izinhlaka, singakha izikhwama zemfucuza ezinesikhumba esingaphandle esiqinile, esingenakuchotshozwa, nesisindo sangaphakathi esiguquguqukayo, esivikelayo. Le ndlela yokwakha enezingqimba eziningi iqinisekisa ukuthi isikhwama singadonswa phezu kwamapulangwe aqinile noma sifakwe emishini yokucindezela ngaphandle kokwehluleka okukhulu. Ezindaweni zokuhweba ezinabantu abaningi, lobu buchwepheshe bunikeza indlela yokuvikela ukwehluleka, okuqinisekisa ukuthi ngisho noma ungqimba lwangaphandle lunemvuthuluka encane, ungqimba lwangaphakathi luvimbela imfucuza ukuba ingaphumi.

Ukuthuthukiswa kokunemba kwe-Gauge ne-Dart Drop Strength

Amadatha esayensi yisindlela esiyinhloko yokubala ubukhulu bokugcina kwesikhwama. Kusigaba sesikhondlo sengqalasela, amasikhwama okugcina kusetyenziswa ngokuvamile ngokuchaza "ukubhala" (ubude), okufana nomlinganiso we-1.5 mil ku-3.0 mil ngokwezinkinga zokusebenza. Kodwa, isilinganiso esibalulekile kangaka yisizinda sokuphefumula kwe-Dart (ASTM D1709), esibhalisa umthelela wokuphefumula ngokuphefumula ngokuzimela. Kwa-Sunho, izindlela zethu zokwenza zihlale zihlanganisa ukuthi izindlela zokuphefumula zibe khulu. Lokhu kusinika ukuthi lapho izinto ezinkulu zihlakazihlaka kusikhwama, isifunda sithabathisa umthelela wokuphefumula ngaphandle kokuthi siphume. Kumaqondiso nezindlela zokuhlakaza, apho izinto ezingavamile zihlakazihlaka ngokuphambuka kakhulu, lokhu kuyisidingo esibalulekile kakhulu sesayensi.

Izindlela Zokubhala Ngokuphelele Ukukhathala Ukungafani Kwesakhiwo

Isibonelo esikhulu kakhulu kukuthi iziphotho zihlala ziyadlala kumgqa wokugcina we-bag; kodwa, ukungafani kwezinhlobo ziyadlala kusuka kumgqa wokugcina. Izibag zokuphatha izinto ezingavumelekile kufanele zibe nezimfushane zokugcina ezinamandla—ezinkulu kakhulu ziyizimfushane zokugcina ngendlela yomkhonto noma ziyizimfushane zokugcina ngendlela yomkhonto wokugcina—okuzosindisa umqondo wokugcina ngokulinganayo. Uma umgqa wokugcina ungamandla, umbiko wokugcina ngokwemithombo eminingi noma emithombo eyisikhwama kuzosindisa umgqa wokugcina ukuthi ahluke, okuzosindisa umqondo wokugcina ngokulinganayo nokuthi isiphotho. Ngokusebenzisa umthwalo wokugcina ngokwekhezi, sizobeka ukuthi umgqa wokugcina we-bag uyisilinganiso somgqa wokugcina wokugcina. Lokhu kubalulekile kakhulu kumathuluzi wokuhlela abantu nasezindaweni zokuhlela abantu, lapho ukugcina izinto ezingavumelekile noma izinto ezingazange zibe yizinhlobo zokuhlukunyezela abantu ngokuphelele kungabikho ukuthi kuyasinda.

Ukuhambisana Kwemithwalo Yokuvimbela Kwezinto Ezingavumelekile Noma Ezisikhwama

Kukusebenzisa ukususa isithakazelo ngokwemisebenzi, ubude bephakathi lwesithakazelo kuncane kunezinkinga zokubona kunezinkinga zokubona. Iibhagi zesithakazelo ezingenakwenzeka ngokuphambuka kufuneka zibe ne-"ukuzimisela kwamandla", okuyinto eyakwenzela ukuba zizimele ngokupheleleyo emaphakathini amahle ayo amahle, i-piping yase-PVC, noma izihlangothi zomthi. Uma ifilm yesilika ayibonakala kakhulu, iyakwenzela ukuba ibe yinkungu ekuthinteni. Ngokuhlela ukuthintana kwezindawo zokuthintana, abasemthwini baphepha iibhagi ezikwenzela ukuba zibe nezimali zokuzimela nakweminyaka yezinkungu. Lokhu kukhangelwa ukuthi umthelelo uqondile kuzo zonke izindawo zebhagi, ukuvikela izindawo eziphambuka kakhulu ezinokuthintela iibhagi ezincane.

Ukuthengiselwa Ngokupheleleyo Ngokwenza Ukuthola Kwamandla Nokuphula Kwezithakazelo

Kusukela kwezindlela zokuhlanganisa nokuthenga, isidingo esiphakeme kakhulu sabhagi yokuqhubeka ngokupheleleyo yokungabonakaliyo kukho ukuthengiswa kwakho okupheleleyo. Kunezinkinga zokuthengiswa kwakho okupheleleyo (TCO) ozokubona ukuthi ziyinkulu kakhulu kunakho okuthengiswa kwakho okwesibini. Amasiteyisheni athandayo ukusebenzisa amabhagi wokugcina amancane noma amabhagi awangabi nempilo ayathola izinkinga ezingafihliweyo zokuthenga kabili, umsebenzi omkhulu wokucleansa izilungiselelo zokugcina, nokuthengiswa kakhulu kwamabhagi wokugcina. Ngokuguqula ku-bhagi yokuqhubeka ngokupheleleyo yokungabonakaliyo, amashishini ayathola ukuthi ayabeka ubhagi bakho bokugcina ngaphezu kwe-30%. Lokhu kubonisa ukuthi izinkinga zokusebenza ziyithi zingaphakamisa ukuthi abaphathi bokugcina bakhetha ubukhulu kunezinkinga zokuthengiswa ngalinye, njengoba ubukhulu kuyisidingo esiphakeme sokugcina indawo yasebenzini ekhuluma nezimali.

Ukuthobeka kwe-UV nokuthobeka kwezikhemikhali kusebenzisa emindeni

Ekugcineni, ubukhulu bakho bokubaluleka kwezibaghi zokuvikela ukuphuma kwezinye izinto kufanele kubhekise ekubalulekeni kwakho kwezinhloso zemvelo. Izibaghi zemithombo yezindawo ziyabhalwa phakathi kwezindawo zokuhlanza ngaphandle kwekhaya noma ziyaboniswa ngamachemikhali amabi okuhlanza. Ukuvuka kwe-UV kungahlela izihluzi zepolymers zomthwakazi wokubaluleka, kwenza ukuthi ibe "yisikhumba" futhi isebenzise ukuphuma kwezinye izinto, okuyisiphelo sokuphula ukubaluleka kwakho kwezibaghi. Izilayini eziningi zokuhlela ziyaboniswa ngamachemikhali okuvuka kwe-UV ne-carbon black ukuze zilungise amathuba akho okusebenza ngaphandle kwekhaya. Ngaphezu kwalokho, ubukhulu bakho bokubaluleka kwezichemikhali kubhekisa ukuthi izibaghi aziyibonisi ukuphula lapho ziyaboniswa ngamafutha, amasolvanti, noma izinkulungwane zokudla eziphansi, ukunikeza indlela yokubaluleka yonke eyenziwa ngokuphelele emva kokususa kuze kube kususwa kwezindawo zokuphuma.
