Ukwethulwa Kolayini Wokugeza Kabusha Wepulasitiki
2023-06-26
Isici sefilimu ye-PE/ifilimu yezolimo,Isikhwama esilukiwe se-PP/isikhwama sethani/isikhwama sokupakisha sokugaywa kabusha nomugqa wokuhlanzaukuthi ingakwazi ukususa ngempumelelo ifilimu yepulasitiki equkethe i-sediment.
Ngokuthuthuka okuqhubekayo kobuchwepheshe bezolimo kanye nokuthuthukiswa kwezinga lokuphila kwabantu, ifilimu yezolimo nefilimu ye-greenhouse iye yasetshenziswa kakhulu kwezobuchwepheshe bezolimo, okuletha izinzuzo ezinkulu ekuthuthukisweni kwezolimo kanye nokwenza ngcono izinhlobo zezitshalo. Kodwa-ke, ukusetshenziswa okubanzi kwe-mulch yezolimo kuletha izinkinga ezinkulu ekungcolisweni komhlaba nasekugayweni kabusha. Ngaphezu kwalokho, ngenxa yezimpawu zokusetshenziswa kwefilimu ye-mulch yezolimo, inenani elikhulu lenhlabathi; futhi kuletha izinkinga ezinkulu ohlelweni lokugaywa kabusha. Ngenxa yalesi simo kanye nezici ze-mulch yezolimo. I-Jiangsu Xinrong Pusi Machinery Co., Ltd. isungule umkhakha wobuchwepheshe wokuhlanza amafilimu ezolimo kanye nokugaywa kabusha komugqa wokukhiqiza i-granulation, oxazulula izinkinga zenhlabathi namanzi ekugayweni kabusha kwefilimu yezolimo. Ngesikhathi esifanayo, ixazulula ubunzima bezobuchwepheshe bokuphelelwa amanzi emzimbeni, ukomisa, i-granulation kanye nokukhishwa okuphezulu. Njengamanje, isetshenziswe kahle eChina. Umzila wenqubo othize umi kanje:
Inqubo yokuhlanza: ukuphakelwa kwebhande - ukuchotshozwa kwefilimu - ukuhlanza okuvunguzayo ngesivinini esikhulu - ukuhlanza kwangaphambili - ukuhlanza ngesivinini esiphansi - umshini wokukhipha ifilimu - ukuhlanza - isifinyi sefilimu - silo.
Ngenxa yokuqukethwe okukhulu kwe-sediment (50-60)%, kunobunzima obuningi ekusetshenzisweni kabusha, futhi inkinga yokuguga ibucayi kakhulu, ikakhulukazi amathuluzi okuchoboza nemishini, okuthinta kakhulu okukhiphayo. Ngokwezici zayo, iphasi lokuqala Umshini ohlanganisiwe we-hydraulic baling and shearing usetshenziselwa ukupakisha ifilimu yepulasitiki engcolile, usike ngo-150-200MM, futhi usike ibhali ngalinye ngemimese engu-5-7, bese wenza ukuhlukaniswa kazibuthe ngemuva kokudlula. ibhande, bese ukhetha insimbi kazibuthe, bese ufaka isikrini sesigubhu. Izinto zikhululiwe esikrinini se-trommel, futhi inhlabathi iqale ikhishwe nge-mesh. Bese ingena ku-crusher. Ngalesi sikhathi, okuqukethwe kuqukethe cishe u-10% we-sediment, okunciphisa kakhulu ukuguga nokudabuka ku-crusher namathuluzi. Impahla echotshoziwe ihlanzwa ngesivinini esikhulu sokuhlanza okuvunguzayo kanye nomshini wokuthungatha, bese ingena kusihlukanisi sokugeza amaphedi. Ipulasitiki inwebeka emanzini, isihlabathi esiqhubekayo sikhishwa ngokushaywa kwe-biaxial, futhi sihlukaniswe ne-sediment, bese singena ekukhuhleni okunesivinini esiphansi ukuze kuhlanzwe okwengeziwe, futhi singena ezingeni elilandelayo lethangi lokuhlanza ukuze kuhlanzwe futhi kuhlukaniswe. Esimeni samakhemikhali, okuqukethwe kwamanzi cishe ku-7-8%. Ngemva kokuba amanzi ehwamukile ngokwemvelo endlini yokugcina impahla ngomoya, akhishwa i-granulated. Isebenzisa ukuphakelwa okuphoqelekile okuseceleni kanye nokuhlunga okuyizigaba ezimbili, kanye ne-granulation yendandatho yamanzi.
Ngokuthuthuka okuqhubekayo kobuchwepheshe bezolimo kanye nokuthuthukiswa kwezinga lokuphila kwabantu, ifilimu yezolimo nefilimu ye-greenhouse iye yasetshenziswa kakhulu kwezobuchwepheshe bezolimo, okuletha izinzuzo ezinkulu ekuthuthukisweni kwezolimo kanye nokwenza ngcono izinhlobo zezitshalo. Kodwa-ke, ukusetshenziswa okubanzi kwe-mulch yezolimo kuletha izinkinga ezinkulu ekungcolisweni komhlaba nasekugayweni kabusha. Ngaphezu kwalokho, ngenxa yezimpawu zokusetshenziswa kwefilimu ye-mulch yezolimo, inenani elikhulu lenhlabathi; futhi kuletha izinkinga ezinkulu ohlelweni lokugaywa kabusha.
