Ngesikhathi senqubo yokukhiqiza, ngoba PVC kuyinto ezwela ukushisa, ngisho nokwengeza izinto ezivimbela ilangabi ezingenayo i-halogen kuzokwandisa izinga lokushisa lokuncibilika futhi kwandise isikhathi sokuzinza ngaphandle kokuncibilika. Lokhu kudinga ukuthi izinga lokushisa lokwakheka nokucubungula i-PVC lilawulwe ngokuqinile. Ikakhulukazi kwi-PVC, ngoba izinga lokushisa lokukhiqiza nokucubungula kwayo liseduze kakhulu nezinga lokushisa layo lokuncibilika, ukuncibilika kuvame ukubangelwa ukulawulwa kokushisa okungenangqondo. Ngakho-ke, izinga lokushisa lokukhipha kufanele linqunywe ngokusekelwe ezicini ezifana nefomula, izici zokukhipha, isakhiwo senjini, isilinganiso sesivinini sesikulufa, indawo yephuzu lokulinganisa izinga lokushisa, ukuphambuka kwethuluzi lokulinganisa izinga lokushisa, kanye nokujula kwephuzu lokulinganisa izinga lokushisa.
Ukulawula ukushisa
Ukulawulwa kwezinga lokushisa kuyisici esibalulekile sokulawula ekusebenzeni kokukhipha. Izinga lokushisa lezici zokulawula ezidingekayo ekubunjweni kokukhipha yizinga lokushisa lemigqomo, izinga lokushisa lobubanzi bomshini, kanye nezinga lokushisa lomlomo odayiwe. Uma izinga lokushisa liphansi kakhulu, ukuncibilika kuzoba kubi, ukubukeka kwepayipi kuzoba buthuntu, izakhiwo zomzimba zizoba zimbi, futhi ikhwalithi yomkhiqizo ngeke ihlangabezane nezidingo: uma izinga lokushisa liphezulu kakhulu, izinto zokusetshenziswa zizoncibilika futhi umkhiqizo uzoshintsha umbala.
Isilinganiso sesivinini sesikulufu
Isilinganiso sesivinini sesikulufo siyanda futhi inani lokukhipha liyakhula, ngaleyo ndlela kuthuthukiswe ukusebenza kahle, kodwa kulula ukubangela ukuncibilika okubi, okubangela ukuthi ingaphakathi lepayipi libe lukhuni namandla ehle. Ngalesi sikhathi, ingcindezi yenjini kufanele ilungiswe ukuze kwandiswe umthamo wokukhiqiza futhi Ikhwalithi ingcono. Ukulawulwa kwezinga lokushisa kwesikulufo kuthinta izinga lokuthuthwa kwezinto, ukuncibilika kwezinto, ikhwalithi yokuncibilika, njll. Ukufakwa kwamapayipi angeziwe kudinga ukujikeleziswa ngamanzi apholile ukuze kuncishiswe izinga lokushisa lenduku yesikulufo, okuwusizo ekuthuthukiseni ikhwalithi yokuncibilika. Izinga lokushisa lamanzi apholile ageleza ngenduku yesikulufo licishe libe ngu-50~70°C.
Isivinini sebhande lokudonsa
Ukulungiswa kwe- isivinini sebhande lokubamba Kubaluleke kakhulu ekusebenzeni kokukhipha kabusha. Izinto zokusetshenziswa ziyancibilikiswa yi-extrusion, futhi zikhishwa njalo enjinini bese kuba yibhande lokudonsa, bese zingena emishinini yokubumba, imishini yokuqandisa, imishini yebhande lokudonsa, njll. Isivinini sebhande lokudonsa kufanele sihambisane nesilinganiso sokukhipha siyavumelana. Ngokuvamile, ngesikhathi sokukhiqiza okuvamile, isivinini sebhande lokudonsa kufanele sibe cishe ngu-1% kuya ku-10% ngokushesha kunesivinini sokukhipha sezinto zokufaka amapayipi.
Ukucindezelwa komoya kanye nengcindezi yokusebenza
Ukucindezelwa komoya ingafutha izinto zokufaka amapayipi ukuze igcine okuthile ukugxila. Kunqunywe ukuthi ingcindezi yokusebenza kufanele ifanele. Ingcindezi yokusebenza incane kakhulu, izihlanganisi zamapayipi aziyindilinga, ingcindezi yokusebenza iphakeme kakhulu, i-mandrel ipholile, ingaphakathi lezihlanganisi zamapayipi liqhekekile, alilingani, futhi ikhwalithi yezihlanganisi zamapayipi iyancipha. Ngesikhathi esifanayo, izidingo zokucindezela zizinzile. Uma ingcindezi ikhuphuka ngokuzumayo futhi ngezinye izikhathi yehla, izihlanganisi zamapayipi zizokwenza kalula ukuthi uqalo oluyindilinga lonakale.
Izinga lokushisa lemishini yokushisa kanye nemishini yokuqandisa
Ukuze kukhishwe imikhiqizo ehlukene yepulasitiki, kusetshenziswa izindlela ezahlukene zokufaka izitsha kanye nezindlela zokuqandisa. izinto eziqandisiwe kungaba yigesi, amanzi noma olunye uketshezi, futhi izinga lokushisa lidinga ukulawulwa. Izinga lokushisa lihlobene kakhulu nokukhiqiza, ukucindezeleka kokushisa komkhiqizo, njll.
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
