Izinhlelo zokunisela zibalulekile ekuphathweni kahle kwamanzi kwezolimo, ezokulungisa ingadi, kanye nezezitshalo. Ukukhetha impahla efanele yempompi kubalulekile ukuqinisekisa ukulethwa kwamanzi kahle, ukunciphisa ukulahleka, kanye nokufeza ukuqina kwesikhathi eside kohlelo. Phakathi kwezinketho ezahlukahlukene zempompi ezitholakalayo, amapayipi e-High-Density Polyethylene (HDPE) avele njengenketho engcono kakhulu kwezicelo zokunisela. Izimfanelo zawo ezihlukile nezinzuzo zokusebenza kwenza ukuba athandwe kakhulu abalimi, onjiniyela, nabakhi ngokufanayo. Lesi sihloko sihluza izici nezinzuzo zamapayipi e-HDPE enzelwe ngokukhethekile izinjongo zokunisela, kusekelwa imininingwane esebenzayo kanye neziphakamiso zemboni.

Amapayipi e-HDPE enzelwe ukubekezelela izimo ezinzima zemvelo ngenkathi egcina ukuguquguquka namandla. Njengengqalasizinda yokusabalalisa amanzi, adinga ukumelana nengcindezi yomshini, ukugqwala kwamakhemikhali, kanye nokuvuza. Ukukhethwa kwempahla yepayipi kuthinta ngqo ukusebenza kahle, izindleko zokugcinwa, kanye nokonga amanzi. Uma kuqhathaniswa nezinto zakudala, i-HDPE inikeza izinzuzo eziningana ezikhangayo, ezibeka njengenketho ehamba phambili ezinhlelweni zokunisela zesimanje.

Lesi sihloko sizohlinzeka ngokuqhathanisa okujulile phakathi kwe-HDPE nezinye izinto zamapayipi ezifana ne-PVC, sixoxe ngezinzuzo eziyinhloko ze-HDPE, futhi sinikeze izincomo mayelana nezicelo zazo ezisebenzayo. Ngaphezu kwalokho, sizothinta izinto zezindleko kanye nemingcele engaba khona ukusiza abenzi bezinqumo bakhe isixazululo esingcono samapayipi ezidingweni zabo zokunisela.

Ukuqonda ukwakheka kwezinto zamapayipi e-HDPE kanye ne-PVC kubalulekile ukuze kuqondwe umehluko ekusebenzeni kwawo. Amapayipi e-HDPE enziwa nge-polyethylene enobuningi obuphezulu, i-polymer ye-thermoplastic eyaziwa ngokuba namandla aphezulu uma iqhathaniswa nobungako bayo. Lokhu kwakha kunikeza i-HDPE ukuguquguquka kwayo okujwayelekile kanye nokumelana kahle nokushayeka kanye nezinto zemvelo.

Ngokuphambene, amapayipi e-PVC (Polyvinyl Chloride) aqinile futhi awaguquguquki kangako, enziwe nge-polymer elula kakhulu ukuqhekeka ngaphansi kwengcindezi noma izinga lokushisa elidlulele. Ngenkathi amapayipi e-PVC ngokuvamile elula ukwenziwa ngezindleko eziphansi, awanawo amandla okuhlala kanye nokubuyiselwa emuva okutholakala kumapayipi e-HDPE.

Isakhiwo samajekelethi emapayipini e-HDPE sinikeza ukumelana okungcono kakhulu namakhemikhali avame ukutholakala enhlabathini nasemanzini, okwenza ukuthi amapayipi e-HDPE angagqwalisi kalula. Amapayipi e-PVC angonakala ngokuhamba kwesikhathi lapho evezwa imisebe ye-UV namakhemikhali athile, kanti ukumelana kwe-HDPE nemisebe ye-UV kuvumela ukusetshenziswa ngaphandle isikhathi eside ngaphandle kokonakala.

Enye umehluko obalulekile ukuguquguquka. Amapayipi e-HDPE angagoba ngomugqa othile ngaphandle kokuqhekeka, okwenza kube lula ukufakwa ezindaweni ezinamavimbeko futhi kunciphise isidingo sezixhumi. Amapayipi e-PVC adinga izixhumi eziningi, ezingandisa ingozi yokuqhekeka kanye nobunzima bokufakwa.

Enye yezinzuzo eziyinhloko zemibhobho ye-HDPE ezolisweni ukumelana kwayo okuhle kakhulu nokugqwala nokuhlaselwa amakhemikhali. Ngokungafani nemibhobho yensimbi noma okunye okwenziwe ngopulasitiki, i-HDPE ayiboli, ayonakali, noma iyancipha lapho ichayeke emsweni, emanyolo, noma enhlabathini enesidi. Lokhu kumelana kwandisa impilo yemibhobho futhi kunciphisa ukuphindwa kokulungiswa, kuqinisekisa ukulethwa kwamanzi okungaguquki iminyaka eminingi.

Ukuvumelana nezimo kwemibhobho ye-HDPE kwenza kube lula kakhulu ukufakwa ezindaweni ezahlukahlukene. Amandla ayo okugoba emakhoneni nasezithinteni kunciphisa isidingo sezinto ezengeziwe nezixhumanisi, ezivame ukuba yizindawo zokuqhekeka. Leli khwalithi futhi livumela imibhobho ukuthi imunce ukunyakaza komhlaba njengokuhlala komhlabathi noma imisebenzi encane yezinyikimo, ivikela uhlelo lokunisela ekulimaleni.

Imibhobho ye-HDPE inokuphila isikhathi eside kudlula iminyaka engu-50 ngaphansi kwezimo ezijwayelekile zokusebenza. Ukuqina kwempahla kukwenza ikwazi ukumelana nokushintsha komfutho wamanzi wangaphakathi, imithwalo yangaphandle evela enhlabathini nemishini, kanye nezimo zezulu ezimbi ngaphandle kokuqhekeka noma ukwehluleka. Lokhu kuqina kuguqulela ezindlekweni zokubuyisela ezincane kanye nokudonsa okuncane kwemisebenzi yokunisela.

Ngenxa yezindlela ezithuthukisiwe zokushisela ezisetshenziselwa ukuhlanganisa imibhobho ye-HDPE, izinhlelo zokunisela ezakhiwe ngale mibhobho zithola ukuqhekeka okuncane kakhulu uma kuqhathaniswa nezinhlelo ezisebenzisa izixhumanisi zemishini noma izinto ezincane. Izixhumanisi ezingenamithungo zakha ukuxhumana okuqinile, okuvimbela ukuqhekeka okunciphisa ukuchitha amanzi futhi kukhuthaze ukunisela okusebenzayo.

Ngenxa yokuthi amapayipi e-HDPE amelana nokugqwala, ukonakala kwe-UV, kanye nomonakalo wemishini, adinga ukugcinwa okuncane kakhulu. Lesi sici siwusizo ezindaweni zezolimo lapho izinsiza zokugcinwa kanye nokutholakala kwabasebenzi kungase kube mkhawulo. Isidingo sokugcinwa okuncane futhi sinciphisa izindleko zokusebenza isikhathi sonke samapayipi okunisela.

Amapayipi e-HDPE ayasebenza futhi afanele izinhlobonhlobo zezicelo zokunisela, okubandakanya ukunisela ngamathonsi, izinhlelo zokufafaza, nokusabalalisa amanzi ezolimo ezinkulu. Ukuvumelana kwawo nokuhlala kwawo kwenza kube kuhle kakhulu kokubili ukufakwa okungaphezulu komhlaba nokungcwatshwa. Ngaphezu kwalokho, amapayipi e-HDPE ahambisana nobuchwepheshe bokunisela besimanje, asekelayo ukusetshenziswa kwamanzi kahle nemikhuba yokulima esimeme.

Naphezu kwezinzuzo eziningi, amapayipi e-HDPE anezinye izinkinga. Ngokuvamile anezindleko eziphakeme ekuqaleni uma eqhathaniswa namapayipi e-PVC, okungaba ukucatshangelwa kumaphrojekthi anomkhawulo wesabelomali. Ngaphezu kwalokho, amapayipi e-HDPE adinga imishini ekhethekile yokushisela kanye nabasebenzi abanekhono ukuze kujoyinwe, okungenzeka kungatholakali kuyo yonke imikhawulo. Kodwa-ke, lezi zinkinga zivame ukudlula ukusebenza kwesikhathi eside nokonga izindleko.

Ngenkathi ukutshalwa kwezimali kokuqala kwamapayipi e-HDPE kungaba ngaphezu kwe-PVC, izindleko zokuba nazo ngokuvamile zithanda i-HDPE lapho kubhekwa ukuqina, ukugcinwa okuncishisiwe, nokulahleka kwamanzi okuncane okuvela emapayipini avuzayo. Ngokuhamba kwesikhathi, ukuncishiswa kokuphinda kufakwe kanye nokonga amandla okuvela ezinhlelweni zokulethwa kwamanzi ezisebenza kahle kwenza i-HDPE ukhetho olonga imali ezindaweni zokunisela.

Amapayipi e-HDPE anikeza izinzuzo eziningi ezenza kube ukhetho oluhle ezinhlelweni zokunisela. Ukumelana kwawo nokugqwala, ukuguquguquka kwawo, ukuqina kwawo, ukumelana nokuvuza, kanye nezidingo zokugcinwa okuphansi kuthinta ngqo ukuthuthukisa ukusebenza kahle kokunisela kanye nokuphila isikhathi eside kohlelo. Noma izindleko zokuqala kanye nezidingo zokufakwa kungaba ngaphezu, izinzuzo ezibanzi ziqinisekisa ukusebenza okuthembekile kanye nokonga isikhathi eside.

Ezamabhizinisi kanye nochwepheshe bezolimo abafuna izixazululo zokufakelwa kwamapayipi ezihlanganisa amandla nokusimama, amapayipi e-HDPE agqama njengenketho engcono kakhulu. Izinkampani ezifana ne-Shijiazhuang Shengshichang Trade CO., Ltd ziqeqeshelwe ukuhlinzeka ngamapayipi e-HDPE asezingeni eliphezulu aklanyelwe ukuhlangabezana nezidingo ezahlukahlukene zokunisela, ziqinisekisa ukuthi uthola imikhiqizo ehambisana namazinga ezolimo yesimanje.

Ukuhlola uhla olubanzi lwezixazululo zamapayipi e-HDPE ezintsha futhi ufunde kabanzi mayelana nezicelo zazo, vakashela i-Imikhiqizo ikhasi. Ngolwazi oluningiliziwe lwenkampani kanye nobuchwepheshe ezixazululweni zemibhobho, bona i-Mayelana Nathi ikhasi. Ngaphezu kwalokho, i-Ikhayaikhasi linikeza imininingwane ephelele ngemikhiqizo yenkampani nokuzibophezela kwayo kwekhwalithi.
