Izixazululo Zezinkinga Ezivamile Ekubunjweni Kokufakwa Kwepayipi le-PVC
Phakathi nenqubo yokubumba umjovo wokufakwa kwamapayipi e-PVC, ezinye izinkinga ezivamile zivame ukuvela, njengezinto ezinganele, izimpawu zokushwabana ezinzima, imigqa yokushisela esobala, nokucwebezela okubi kwemikhiqizo. Lezi zinkinga azithinti nje kuphela ukubukeka kwayo yonke imikhiqizo kodwa zingase zibe nomthelela ekuzinzeni kwayo kwesakhiwo kanye nempilo yesevisi. Ngenhlanhla, lezi zinkinga zingaxazululwa ngempumelelo ngokusebenzisa izindlela zesayensi nokulungiswa okufanele.
Lapho ubhekene nenkinga yokungagcwaliswa okwanele kwesikhunta, ngokuvamile kubangelwa ukushisa okuphansi komjovo kanye nokungabi namanzi. Ngalesi sikhathi, ngokufanelekile ukwandisa izinga lokushisa lokushisa, ikakhulukazi ku-nozzle, kungathuthukisa ngempumelelo i-plasticization kanye ne-fluidity yezinto. Ukwengeza, uma umjikelezo wokubumba umjovo usethwe waba mfushane kakhulu noma ukunikezwa kwezinto ezibonakalayo kunganele, ukukhulisa isikhathi somjovo kanye nevolumu yokuncibilika nakho kuyisinyathelo esibalulekile sokuxazulula inkinga.
Odabeni lwamamaki okuncipha aqinile, isisombululo sifana naleso sezinto ezinganele. Kuyadingeka ukuhlola ukuthi ingabe ingcindezi yomjovo iphansi kakhulu, ukuthi isikhathi sengcindezi yokubamba sanele yini, nokuthi isikhathi sokupholisa sifanelekile yini. Ukulungiswa okufanele kwale mingcele kungathuthukisa kakhulu ikhwalithi yomkhiqizo oqediwe.
Bese kuba nenkinga yemigqa yokushisela esobala, evame ukubangelwa ukushisa kwempahla ephansi noma ukucindezela komjovo okwanele. Ukwandisa izinga lokushisa lokushisa lomgqomo, ikakhulukazi ku-nozzle, nokwandisa ngokufanele ukucindezela komjovo noma isivinini kuyizixazululo ezisebenzayo. Ngaphezu kwalokho, ukuthuthukisa ukusebenza kokukhipha isikhunta kanye nokulungisa ubukhulu besango nakho kubaluleke kakhulu.
Ukuthuthukisa isicwebezelisi somkhiqizo ikakhulukazi kuncike ekuthuthukiseni uketshezi lwento ye-PVC.
Lokhu akubandakanyi nje kuphela ukulungisa izinga lokushisa nokucindezela kodwa futhi kuhlanganisa nokuthuthukisa isistimu yokupholisa isikhunta kanye nedizayini yokukhipha umoya. Ukulungiswa kokubunjwa okunengqondo kanye nokwelashwa kokomisa impahla eluhlaza nakho kuyizici ezingenakuzitshwa.
Ngalokhu kuhlaziya okuningiliziwe nokuqondile nezisombululo, singakwazi ukunqoba ngempumelelo izinkinga esihlangabezane nazo enqubweni yokubumba umjovo wokufakwa kwamapayipi e-PVC futhi sikhiqize imikhiqizo yekhwalithi ephezulu. Lokhu akuthuthukisi nje kuphela ukuncintisana kwemakethe kwemikhiqizo kodwa futhi kuhlangabezana nezidingo zabathengi zokufakwa kwepayipi le-PVC lekhwalithi ephezulu.
