Esimeni sanamuhla sezimboni, ukukhishwa kwamapayipi epulasitiki kushintsha imikhakha eyahlukene ngokunikeza izixazululo ezisebenza kahle, ezingabizi kakhulu, neziguquguqukayo. Ikhono lokukhiqiza amapayipi ngobukhulu obuhlukahlukene kanye nezinto zokwakha lenze i-extrusion yamapayipi epulasitiki ibe yinto ekhethwayo yezinhlelo zokusebenza eziningi. Kulesi sihloko, sizohlola ukusetshenziswa okuphezulu kwe-extrusion yamapayipi epulasitiki nokuthi angazuzisa kanjani ibhizinisi lakho.
Iyini i-Plastic Pipe Extrusion?
I-extrusion yamapayipi epulasitiki iyinqubo yokukhiqiza lapho izinto zepulasitiki zincibilika futhi zakhiwe zibe amapayipi aqhubekayo. Le ndlela ivumela ukwakhiwa kwamapayipi anezilinganiso ezilinganayo kanye nezakhiwo, okwenza kube kulungele uchungechunge olubanzi lwezinhlelo zokusebenza. Ngokukhula kwesidingo sezinto ezihlala isikhathi eside nezingasindi, i-extrusion yamapayipi epulasitiki izuza amandla kuzo zonke izimboni eziningi.
1. Izinhlelo Zokuhlinzeka Ngamanzi Nokusabalalisa
Esinye sezicelo ezivelele kakhulu zokukhishwa kwamapayipi epulasitiki kusezinhlelweni zokuphakela nokusatshalaliswa kwamanzi. Amapayipi epulasitiki, ikakhulukazi lawo enziwe nge-polyvinyl chloride (PVC) ne-polyethylene (PE), alungele ukuthutha amanzi aphuzwayo ngenxa yokumelana nokugqwala kanye nesisindo esiphansi.
Ngokombiko we-American Water Works Association, amapayipi epulasitiki athatha cishe u-70% wokufakwa kwamanzi okusha e-United States. Lokhu kukhula kokutholwa kungase kubangelwe ukuphila kwabo isikhathi eside, ukubekeka kalula, kanye nezindleko zokunakekela ezincishisiwe uma kuqhathaniswa nezinto ezivamile ezifana nensimbi nokhonkolo.
2. Ukuphathwa Kwendle kanye Namanzi Angcolile
I-extrusion yamapayipi epulasitiki idlala indima ebalulekile ekulawulweni kwendle namanzi angcolile. Ukuqina nokumelana namakhemikhali kwamapayipi epulasitiki kuwenza afaneleke ukuphatha indle, amanzi eziphepho, nokungcola kwezimboni.
Isibonelo, amapayipi e-polyethylene (i-HDPE) e-high-density polyethylene (HDPE) avame ukusetshenziswa ezinhlelweni zendle ngenxa yekhono lawo lokumelana nezimo ezinzima futhi anciphise ukungena nokuphuma. Ucwaningo olwenziwa yi-Water Environment Federation lubonise ukuthi amapayipi e-HDPE angahlala iminyaka engaphezu kuka-100 ekufakweni kwendle, okunciphise kakhulu isidingo sokushintshwa nokulungiswa.
3. Izinhlelo Zokuchelela Kwezolimo
Umkhakha wezolimo uphinde wamukele ukukhishwa kwamapayipi epulasitiki kumasistimu okunisela. Amasistimu okunisela ama-Drip and sprinkler asebenzisa amapayipi epulasitiki ukuze asabalalise amanzi ngendlela efanele, anciphise ukumoshakala futhi athuthukise isivuno sezitshalo.
Umbiko weFood and Agriculture Organisation (FAO) uveza ukuthi ukusetshenziswa kwe-drip irrigation kungakhuphula ukusebenza kahle kwamanzi ngo-30-50% uma kuqhathaniswa nezindlela zakudala. Imvelo engasindi yamapayipi epulasitiki iwenza kube lula ukuwafaka nokuwahambisa, okwenza kube lula ukukhanga kwawo ezinhlelweni zezolimo.
4. Ezokuxhumana kanye Nepayipi likagesi
I-extrusion yamapayipi epulasitiki ibalulekile ezimbonini zokuxhumana ngocingo nasezimbonini zikagesi ukuze kuvikelwe futhi kufakwe ikhebula. Amapayipi epayipi enziwe nge-PVC noma i-HDPE asetshenziselwa ukuvikela izintambo zikagesi ekulimaleni ngokomzimba nasezicini zemvelo.
Ngokusho kweNational Electrical Contractors Association, ukusebenzisa ipayipi lepulasitiki kunganciphisa isikhathi sokufakwa kanye nezindleko zabasebenzi ngenxa yezakhiwo zayo ezingasindi kanye nokuphatheka kalula. Ngaphezu kwalokho, amapayipi epulasitiki amelana nokugqwala kanye nomswakama, okuqinisekisa ubude bezinhlelo zikagesi ezivikelayo.
5. Ukwakha Nokwakha
Embonini yezokwakha neyokwakha, i-extrusion yamapayipi epulasitiki isetshenziselwa izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa amasistimu okukhipha amanzi, amapayipi, kanye nezinhlelo ze-HVAC (zokushisa, ukungena komoya kanye nezomoya). Ukuhlukahluka kwamapayipi epulasitiki kuvumela ukuhlanganiswa okungenamthungo ekwakhiweni okusha nokulungiswa kabusha.
Inhlolovo eyenziwe yi-International Association of Plumbing and Mechanical Officials (IAPMO) ithole ukuthi u-60% wochwepheshe bokufaka amapayipi bakhetha amapayipi epulasitiki ukuze afakwe ngenxa yezindleko zawo ezisebenzayo kanye nokuthembeka. Imvelo engasindi yamapayipi epulasitiki yenza kube lula ukuthutha nokufakwa, okuholela ezikhathini zokuphothulwa kwephrojekthi ngokushesha.
I-Case Study: Ukuqaliswa Okuyimpumelelo Ekuthuthukisweni Kwamadolobha
Ucwaningo oluphawulekayo lomthelela we-plastic pipe extrusion lungabonwa kuphrojekthi yokuthuthukiswa kwedolobha ledolobha elikhulu. Umasipala ukhethe amapayipi e-HDPE ezinhlelweni zawo ezintsha zokusabalalisa amanzi kanye nendle.
Ngokusebenzisa ubuchwepheshe bamapayipi epulasitiki, idolobhakazi libike ukwehliswa kwezindleko zokuwafaka ngo-30% kanye nokwehla okukhulu kwezigameko zokuvuza kwamanzi. Ukwengeza, isikhathi eside sokuphila kwamapayipi e-HDPE kunciphisa isidingo sokulungiswa kwesikhathi esizayo, ekugcineni kwazuzisa isabelomali sedolobha futhi kwathuthukisa izinga lempilo kubahlali.
Ukusetshenziswa okuhlukahlukene kokukhipha amapayipi epulasitiki kuguqula izimboni ngokuhlinzeka ngezixazululo ezisebenzayo, ezihlala isikhathi eside, nezingabizi kakhulu. Kusukela ezinhlelweni zokuhlinzeka ngamanzi kuya kwezolimo kanye nezokuxhumana, izinzuzo zokusebenzisa amapayipi epulasitiki ziyabonakala.
Njengoba izimboni ziqhubeka nokuthuthuka, ukuqonda ukusetshenziswa kwe-extrusion yamapayipi epulasitiki kunganika amabhizinisi amandla okwenza izinqumo ezinolwazi ezithuthukisa ukusebenza kahle nokusimama. Ngokukhetha amapayipi epulasitiki, izinkampani azigcini nje ngokutshala imali emkhiqizweni onokwethenjelwa kodwa futhi zifaka isandla ekusaseni eliluhlaza, elisebenza kahle kakhulu. Noma ngabe ubambe iqhaza kwezokwakha, ezolimo, noma izinsiza zikamasipala, ukwamukela ukukhishwa kwamapayipi epulasitiki kungaba umnyakazo wakho olandelayo wamasu.
