Izimo zenqubo yokwakheka kwe-extrusion yepayipi le-CPVC zifana nezezijwayelekile Ipayipi le-PVC , kodwa umehluko uwukuthi imfuneko yekhwalithi yezingxenye zemishini yokwenza i-extrusion iphakeme; Imfuneko yokulawula ububanzi bokuguquguquka kwezinga lokushisa lenqubo iqinile kakhulu.
(1) Ukulandelana kwenqubo yokwakheka kwamapayipi e-CPVC:
kala zonke izinhlobo zezinto zokusetshenziswa ngokwefomula yezinto zokwakha ipayipi le-CPVC→Faka izinto zokusetshenziswa emshinini wokuxuba bese uxuba ngokulinganayo→Hlanganisa kahle, uphole bese uvuselela→yenza izinto zokusetshenziswa ezenziwe ngepulasitiki zibonise isimo esincibilikisiwe→Ishubhu lokwakha isikhunta lingenalutho→Ukusetha ukupholisa ububanzi bokusetha i-Vacuum setting→Pholisa ipayipi ngethangi lamanzi okupholisa→khumula→ uphawu lokuhlonza→ukusika→Ukwandiswa kokuphela kwepayipi→hlola→Ukupakisha endlini yokugcina impahla
(2) Ukukhetha imishini:
Hlanganisa izithako ngomshini wokuxuba onesivinini esikhulu, isivinini sokujikeleza esidingekayo sisukela ku-800 kuya ku-1,000 r/min, simbozwe ngedivayisi yokukhipha umoya. Ngemva kokuba izinto zokusetshenziswa zixutshwe ngokulinganayo, faka umshini wokuxuba okupholisa, isivinini siba siphansi, ungapholiswa ngamanzi okupholisa ajikelezayo.
I-extruder eyodwa noma i-extruder ephindwe kabili ingasetshenziswa ukwenza izinto zokusetshenziswa zibe yipulasitiki. Uma usebenzisa i-extruder eyodwa, isakhiwo se-screw kufanele sijuliswe kancane kancane ekujuleni kwentambo.
Uma usebenzisa i-extruder enezikulufo ezimbili, uhlobo lokujikeleza oluhambisanayo kufanele lukhethwe.
Uma i-extruder eyodwa yesikulufo ikhipha izinto zokusetshenziswa zepulasitiki, imishini kufanele ibe nedivayisi yokukhipha umoya engcono; Ifanele ukupholisa ngamanzi ajikelezayo noma uwoyela ojikelezayo. Ukushintshashintsha kwezinga lokushisa kwenqubo kufanele kulawulwe cishe ku-± 5℃. I-extruder ye-CPVC iyafaneleka. Akukho plate enezimbobo phakathi komgqomo we-extruder kanye nesikhunta sokubumba; idivayisi yokuvikela ukulayisha ngokweqile kufanele inikezwe emsebenzini wesikulufo.
(3) Ukusebenza kwenqubo yokubumba kanye nokulawula izinga lokushisa:
①I-resin ye-CPVC kufanele yomiswe kuhhavini ongama-80 amahora ama-2-4 ukuze kususwe umswakama ezintweni ezingavuthiwe
②Ngemva kokulinganisa, izinto zokusetshenziswa zixutshwa emshinini wokuxuba onesivinini esikhulu, futhi izinga lokushisa lezinto licishe libe ngu-115℃.
③Izinto ezixuba ngesivinini esiphezulu zipholiswa ku-mixer yesivinini esiphansi kuze kube yilapho izinga lokushisa lezinto lifinyelela cishe ku-40℃.
⑷Amaphuzu ayisihluthulelo okusebenza kwenqubo:
Ukubumba kwe-extrusion kwepayipi le-CPVC kunzima kakhulu uma kuqhathaniswa nokubumba kwe-extrusion kwepayipi le-PVC. Ngenxa ye-viscosity ephezulu kanye nokugeleza okungekuhle kokuncibilika kwe-PVC okune-chlorine, kunzima ukwakheka. Futhi ukuncibilika kulula ukubola enqubweni yokukhiqiza, ngakho-ke izinkinga ezilandelayo kufanele zinakwe ekukhiqizweni kokubumba kwe-extrusion kwe-polyvinyl chloride resin ene-chlorine:
①I-resin ye-PVC ene-chlorine kumele yomiswe ngaphambi kokuba ifakwe ekukhiqizweni. Kufanele yomiswe kuhhavini ongu-80℃ amahora ama-2 ~4. Uma kudingeka, izinto zokusetshenziswa kufanele zivikelwe ngesikrini se-mesh esingu-40 kanye, bese zifakwa e-hopper ye-extruder ukuze zikhiqizwe.
②Kufanele kuqashelwe ukukhethwa kwefomula yezinto zokusetshenziswa zombhobho wokubumba, iziqinisi kanye nezinye izithako zokucubungula, okufanele ziqinise ukugeleza kokuncibilika futhi zithuthukise ukuzinza kokushisa kwezinto zokusetshenziswa. Hlanganisa ifomula kahle kuqala uma kudingeka. Thatha isivivinyo sesampula kuhhavini ongu-230℃ amahora ama-2. Uma kungekho sici esicacile sokushintsha kombala nokubola, kubonisa ukuthi ukukhethwa kwezinto ezisizayo kunengqondo futhi kunengqondo.
③Izinga lokushisa lenqubo yokukhipha ipayipi le-CPVC liphakeme kancane kunezinga lokushisa lenqubo yokukhipha ipayipi le-PVC. Kodwa-ke, kufanele kuqashelwe ukuthi ukushintshashintsha kokulawula izinga lokushisa akufanele kube ngaphezu kuka-± 5℃.
④Enqubweni yokukhiqiza ipayipi le-CPVC, uma kukhona ukwehluleka kukagesi, ukwehluleka kwemishini, izimpawu zokubola kokuncibilika noma igesi yoketshezi emlonyeni wesikhunta, kufanele iyeke ngokushesha ukuphakela ku-cylinder, isebenzise i-resin ye-PVC ukususa ukuncibilika kwe-CPVC kusikhunta, bese iyeka phansi ukuze kususwe iphutha.
⑤ Igesi ye-HCI ekhishwa ngesikhathi sokubola kwe-CPVC iyingozi emzimbeni womuntu, ngakho-ke naka i-workshop yokukhiqiza ngokusebenzisa
⑥Kusilinda esikhiphayo esisetshenziselwa ukukhiqiza i-resin ye-CPV, ukugeleza kokuncibilika kwesikulufu kanye nesikhunta sokubumba kufanele kuphathwe ngesivikelo sokugqwala ukuze kwandiswe impilo yenkonzo yezingxenye zemishini.
⑦Isembozo kufanele simboze indawo yokukhipha umoya ukuze kube lula ukukhishwa komhwamuko wamanzi.
⑧Sebenzisa i-extruder ukuze ubumbe i-CPVC tube extrusion. Kufanele unake izimo zokusebenza ezifana nokuqina kokulawula izinga lokushisa lokukhipha kanye nenqubo yesilinda ye-extruder. Uma lezi zimo ezimbili zingahlangabezani nezidingo zokukhiqiza, ubumbe i-extrusion tube ye-CPVC kufanele kube nzima kakhulu, noma kungenzeki nhlobo.
⑨Uma ukhiqiza ipayipi le-CPVC, isikulufu kufanele sibe nedivayisi yokushisa nokupholisa, futhi ukuzinza kokushisa kwenqubo kufanele kulungiswe futhi kulawulwe ngokufanele, ukuze kuthuthukiswe ukugeleza kwezinto ezincibilikisiwe futhi kuqinisekiswe ikhwalithi yokwakha imikhiqizo.
⑩Uma udonga lwangaphakathi lwepayipi yokwakha lungalingani, izithasiselo zokucubungula i-acrylate (noma ama-copolymer) kufanele zengezwe kufomula yezinto zokusetshenziswa ukuze kuthuthukiswe izinga lokushisa lokuncibilika kwe-CPVC ne-PVC; okwamanje, ukulawulwa kokuzinza kokushisa kwe-mandrel.
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.
