Ukuphathwa kahle kwamanzi kuyinselele ebalulekile ebhekwa amabhizinisi ezolimo nemiphakathi emhlabeni wonke. Njengoba ukushoda kwamanzi kuba ukukhathazeka okukhulu, isidingo sezixazululo zokunisela ezisimeme siyanda. Esinye sezixazululo esithola ukubuyekezwa okubanzi ukusetshenziswa kwemibhobho ye-HDPE ekunisela. Imibhobho ye-High-Density Polyethylene (HDPE) inikeza izinzuzo eziningi ezingagcini nje ngokuthuthukisa ukonga kwamanzi kodwa futhi zinikele ekusimameni kwemvelo nasekusimeni kwezindleko. Lesi sihloko sihluza izinzuzo eziningi zemibhobho ye-HDPE ekunisela nokuthi zisiza kanjani ukwakha ikusasa elisimeme kakhudlwana, ngemininingwane efanele abaholi bemboni njengeShijiazhuang Shengshichang Trade CO., Ltd.

Ukonga amanzi kubaluleke kakhulu enkonzweni yokunisela, kanti izhubu ze-HDPE zihamba phambili kule ndawo ngenxa yezixhumanisi zazo ezingavuza kanye namandla azo aphezulu okuvala. Ngokungafani nezinto zakudala ezifana nensimbi noma ukhonkolo, izhubu ze-HDPE zisebenzisa ukushisela okuhlanganisa ukushisa ukudala izixhumanisi eziyikho konke, ukuqeda ukuvuza okubangelwa izixhumanisi zemishini. Lokhu kusebenza okungavuza kuqinisekisa ukulethwa kwamanzi okusezingeni eliphezulu ezitshalweni, kunciphise ukuchitha futhi kusekele ezolimo ezisimeme. Ingaphakathi elibushelelezi lezihubhu ze-HDPE liphinde livimbele ukuqoqana kwezinto ezincane, ligcine ukugeleza kwamanzi kungashintshi futhi kunciphise izidingo zokugcinwa. Ukufaka izhubu ze-HDPE ezinhlelweni zokunisela kuholela ekuphathweni okungcono kwezinsiza futhi kunganciphisa kakhulu izikweletu zamanzi ezinkampanini zezolimo.

Amaphrojekthi amaningi esimanje okunisela asebenzisa lesi sici, abeka phambili ukonga amanzi esikhathini eside kanye nesibopho semvelo. Amabhizinisi anentshisekelo yokuhlola izixazululo zokunisela ezihlala njalo angathola izinketho ezinemininingwane ngokuvakashela ikhasi le-Imikhiqizo.

Ubunzima obuncane bezishimula ze-HDPE buhambisana nokuncipha kokusetshenziswa kwamandla kuyo yonke iminyaka yesistimu yokunisela. Okokuqala, ukuthuthwa nokufakwa okulula kusho ukusetshenziswa okuphelele kukaphethiloli nokukhishwa okuncane kwegesi elishisayo ngesikhathi sokwakhiwa. Uma kuqhathaniswa nezinye izinto ezisindayo njengensimbi noma insimbi eqinile, izishimula ze-HDPE zingaphathwa ngamaqembu amancane nemishini elula, okunciphisa izinqubo ezisebenzisa amandla amaningi. Ngaphezu kwalokho, isilinganiso sokungqubuzana sezishimula ze-HDPE siphelele, okunciphisa amandla okumpompa adingekayo ukuhambisa amanzi ngamanethiwekhi okunisela. Lokhu kusebenza kahle kwamandla akugcini nje ngokunciphisa izindleko kodwa futhi kuhambisana nemizamo yomhlaba wonke yokunciphisa ukukhishwa kwekhabhoni kwezolimo.

I-Shijiazhuang Shengshichang Trade CO., Ltd yaziwa ngokuhlinzeka ngamapayipi e-HDPE asezingeni eliphezulu ahambisana nalezi zinzuzo zokonga amandla. Ukuzibophezela kwabo ekulethweni kwemikhiqizo enobungani nemvelo kusekela amakhasimende afuna ukwenza kahle ukunisela ngomthelela omncane emvelweni.

Enye yezinzuzo ezibaluleke kakhulu zamapayipi e-HDPE ukuqina kwawo okungajwayelekile nokumelana nokugqwala. Ngokungafani namapayipi ensimbi, i-HDPE ayiboli, ayonakali, noma iyancipha lapho ichayeke emanzini, emakhemikhali, noma ezimweni zobumba ezivame ukutholakala ezinhlelweni zokunisela. Lokhu kumelana kwandisa impilo yengqalasizinda yokunisela, ngokuvamile kudlula iminyaka engu-50 ngaphansi kwezimo ezijwayelekile. Ukuncishiswa kokuphindwa kokushintshwa kwamapayipi kunciphisa izindleko zokugcinwa nokusebenza, kunikeze inzuzo enkulu yokutshalwa kwezimali kumaphrojekthi okunisela.

Ngaphezu kwalokho, amapayipi e-HDPE ayaguquguquka kakhulu, okuwavumela ukuthi akwazi ukumelana nokunyakaza komhlabathi, ukuhlala komhlabathi, ngisho nemisebenzi yezinyikima ngaphandle kokuqhekeka noma ukuphuka. Lokhu kuguquguquka kunciphisa ubungozi bokuvuza nokwehluleka kohlelo, kuqinisekisa ukulethwa kwamanzi okuthembekile unyaka nonyaka. Ezinkampanini ezifuna izingxenye zokunisela ezithembekile, amapayipi e-HDPE amele isixazululo esihlala njalo esisekelwa ukusebenza okufakazelwe.

Ukwazisa ngemvelo kuyinto eyinhloko ekwakhiweni kokunisela kwesimanje, futhi amapayipi e-HDPE ahamba phambili ngokuhambisana nezimiso zomnotho oyindilinga. I-HDPE iyithermoplastic engasetshenziswa kabusha, okusho ukuthi ekupheleni kwempilo yayo yesevisi, impahla yepayipi ingacutshungulwa kabusha futhi isetshenziswe kabusha ekwenzeni imikhiqizo emisha. Leli khono lokusebenzisa kabusha linciphisa udoti wepulasitiki nokusetshenziswa kwezinsiza uma kuqhathaniswa nezinye izinto ezingasetshenziswa kabusha.

Ngokukhetha imibhobho ye-HDPE, amaphrojekthi ezolimo anikela ekunciphiseni umthelela ombi emvelweni nasekukhuthazeni ukusetshenziswa kwezinto ezisimeme. I-Shijiazhuang Shengshichang Trade CO., Ltd inikeza imikhiqizo ye-HDPE egcizelela izici ezihambisana nemvelo, isekela amakhasimende azibophezele ezindleleni zokulima ezisimeme. Ngeminye imininingwane ngemicimbi yenkampani esebenza ngendlela esimeme, sicela uvakashele ikhasi le-Mayelana Nathi.

Imibhobho ye-HDPE yakhelwe ukumelana nezinto eziningi ezithinta ingqalasizinda yokunisela. Lokhu kufaka phakathi imisebe ye-UV evela elangeni, amazinga okushisa aphezulu, amakhemikhali omhlabathi, nokuhlikihla. Isakhiwo sephethiloli se-HDPE siqinisekisa ukuthi imibhobho ihlala iqinile futhi ingonakali ngisho nasezindaweni eziyinselele.

Ngaphezu kwalokho, ukuguquguquka kwe-HDPE nokumelana nomthelela kusiza ukuvimbela ukulimala okubangelwa imithwalo engalindelekile noma ukushintsha komhlaba, okuyizinto ezivame ukwenzeka emapulazini. Lokhu kusebenza okuqinile kunciphisa amathuba okuvuza nokuyeka ukusebenza kohlelo, kuqinisekisa ukunisela okuqhubekayo nempilo yezitshalo. Abasebenzisi abafuna izixazululo zokunisela ezihlala njalo bangahlola uhla olugcwele lwezinketho zemibhobho ye-HDPE ku- Imikhiqizo ikhasi.

Ukufakwa kwamapayipi e-HDPE kuvame ukubandakanya ukuphazamiseka okuncane kobumba uma kuqhathaniswa namapayipi aqinile endabuko. Ukuvumelana kwawo nokuba kukhanya kwenza kube nokwenzeka ukusebenzisa ubuchwepheshe bokufaka izintambo ongazidwebi, njengokugrumbula okumile okumile nokudabula amapayipi. Lezi zindlela zinciphisa ukugrumbula, zigcine isakhiwo sobumba semvelo futhi zinciphise umthelela ezitshalweni ezikhona kanye nemvelo.

Lokhu kuphazamiseka okuncishisiwe kunenzuzo ikakhulukazi ezindaweni ezibucayi zezolimo lapho ubuqotho bobumba bubalulekile emiphumeleni yezitshalo. Ngaphezu kwalokho, ukufakwa kwezintambo ongazidwebi kunciphisa izindleko zabasebenzi nokubuyiselwa, kwenze amapayipi e-HDPE abe inketho esebenza kahle kwezindleko kumaphrojekthi amanzi wesimanje.

Ikhwalithi elula yemitshiza ye-HDPE ayenzi nje ukufakwa kube lula kodwa futhi yehlisa kakhulu ukukhishwa kwezinto ezithuthwa. Ngoba imishayo eminingi ingathuthwa ngomthwalo owodwa, izidingo zokuhamba ziyancipha, kunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi elibangela ukufudumala komhlaba. Lokhu kusebenza kahle kuyinto ebalulekile emabhizinisini afuna ukwehlisa ukukhishwa kwawo kwe-carbon.

Izindleko zokuthutha eziphansi nazo zenza imishayo ye-HDPE ifinyeleleke futhi ibe nentengo ephansi kakhulu kumaphrojekthi amakhulu ezolimo, okufaka isandla ekwabiweni okungcono kwezinsiza kanye nokwanda kwamaphrojekthi.

Ipayipi le-HDPE lokunisela linikeza isixazululo esibanzi samabhizinisi ahlose ukuthuthukisa ukuphathwa kwamanzi, ukunciphisa umthelela emvelweni, nokwehlisa izindleko zokusebenza. Ukusebenza kwayo okungavuqi amanzi kuthuthukisa ukonga amanzi, kanti isisindo sayo esilula nesikhuthazayo kunciphisa ukonga amandla, ukunciphisa ukuphazamiseka komhlabathi, nengqalasizinda ehlala njalo. Ukusebenziseka kabusha kwezinto ze-HDPE kuqinisa indima yazo ekukhuthazeni imikhuba yokulima esimeme.

Ezamabhizinisi ezolimo kanye nabasebenzi abaqeqeshiwe abanakekela izimisele, ukutshala imali emapayipini e-HDPE asezingeni eliphezulu avela kubahlinzeki abathembekile njenge-Shijiazhuang Shengshichang Trade CO., Ltd kuvumela ukusetshenziswa kwezinhlelo zokunisela ezihambisana nemvelo futhi eziphumelelayo. Ukwamukela lezi zixazululo kusekela imizamo yomhlaba wonke maqondana nokusimama futhi kuqinisekisa ukusetshenziswa okuhle kwezinsiza ezizukulwaneni ezizayo.

Ukuhlola uhla olubanzi lwezixazululo zamapayipi e-HDPE futhi ufunde kabanzi ngezinketho zokunisela ezisimeme, vakashela i-Ikhaya ikhasi.
