Uthango lwe-PVC lwenziwa ngomshini we-screw extrusion ophindwe kabili.
I-PVC extrusion iyinqubo yokukhiqiza enesivinini esikhulu lapho ipulasitiki eluhlaza incibilikiswa khona bese yenziwa iphrofayili ende eqhubekayo. I-Extrusion ikhiqiza imikhiqizo efana namaphrofayili epulasitiki, amapayipi epulasitiki, izinsimbi ze-PVC zedekhi, amafreyimu efasitela e-PVC, amafilimu epulasitiki, amashidi, izintambo, kanye namaphrofayili ocingo lwe-PVC, asetshenziswa kabanzi emikhakheni eminingi.
Le nqubo ye-extrusion iqala ngokuphakela inhlanganisela ye-PVC kusuka ku-hopper kuya emgqonyeni we-extruder. I-compound incibilika kancane kancane amandla emishini akhiqizwa izikulufu eziphendukayo kanye nama-heaters ahlelwe eduze komgqomo. I-polymer encibilikisiwe ibe isiphoqelelwa ibe yi-die, noma ebizwa ngokuthi isikhunta se-extrusion, esilolonga inhlanganisela ye-PVC ibe yisimo esithile, njengesigxobo socingo, isitimela socingo, noma amakhethini othango aqina ngesikhathi sokupholisa.
Ku-extrusion ye-PVC, i-compound material eluhlaza ngokuvamile iyindlela yempushana enamandla adonsela phansi asuka ku-hopper efakwe phezulu emgqonyeni we-extruder. Izithasiselo ezifana ne-pigment, i-UV inhibitors kanye ne-PVC stabilizer zivame ukusetshenziswa futhi zingaxutshwa kunhlaka ngaphambi kokufika ku-hopper. Ngakho-ke, mayelana nokukhiqizwa kocingo lwe-PVC, siphakamisa ukuthi amakhasimende ethu ahlale nombala owodwa kuphela ngokulandelana, noma izindleko zokushintsha isikhunta se-extrusion zingaba phezulu. Kodwa-ke, uma amakhasimende kufanele abe namaphrofayili anemibala ngokulandelana, imininingwane ingaxoxwa.
Le nqubo inokuningi okufanayo nokubunjwa komjovo wepulasitiki kusukela endaweni yobuchwepheshe be-extruder, nakuba ihluke ngokuthi ngokuvamile inqubo eqhubekayo. Nakuba i-pultrusion inganikeza amaphrofayili amaningi afanayo ngobude obuqhubekayo, ngokuvamile ngokuqiniswa okungeziwe, lokhu kufezwa ngokukhipha umkhiqizo oqediwe ngaphandle kwesikhunta esikhundleni sokukhipha i-polymer encibilikayo ngokusebenzisa isikhunta. Ngamanye amazwi, ubude bephrofayela yocingo, njengokuthunyelwe, ama-rails, nama-picket, konke kungenziwa ngokwezifiso ngobude obuthile. Ukuze uthole izibonelo, uthango olugcwele oluyimfihlo lungase lube ngu-6ft ubude no-8 ft ububanzi, futhi lungaba ukuphakama okungu-6ft no-6 ft ububanzi. Abanye amakhasimende ethu, bathenga izinto zocingo ezingavuthiwe, bese besika ubude obuthile eshabhu yabo yokusebenzela, bese benza uthango olukhethekile ukuze bahlangabezane nazo zonke izidingo zamakhasimende abo.
Ngakho-ke, sisebenzisa ubuchwepheshe be-mono extrusion ukukhiqiza izigxobo zothango lwe-PVC, ama-rails namapikikhethi, futhi sisebenzisa ubuchwepheshe bomjovo nemishini ukukhiqiza amakepisi wokuposa, izixhumi, namaphoyinti epiki. Noma ngabe yiziphi izinto zokwakha ezenziwe ngemishini yokukhipha noma yokujova, onjiniyela bethu bazolawula ukuthi imibala ingabekezelelani ukusuka ekugijimeni kuye komunye. Sisebenza embonini yocingo, sazi ukuthi amakhasimende anendaba nani, sibasize bakhule, lokho kuyi-FenceMaster's Mission kanye nenani.
