Abantu abaningi abayazi i-polyethylene e-chlorine, futhi njengoba igama liphakamisa, abantu abaningi kufanele bakwazi ukubona kuphela ukuthi iyimpahla yamakhemikhali. Inenqubo ebizwa ngokuthi i-extrusion molding, esabaluleke kakhulu enqubweni yokukhiqiza. Ngakho-ke namuhla, yini okufanele siyinake phakathi nenqubo yokubumba i-extrusion yalo mkhiqizo? I-Chlorinated polyvinyl chloride
1. Kufomula yempahla eluhlaza yokwenza amapayipi, ukunakwa kufanele kukhokhwe ekukhetheni ama-stabilizers nezinye izinsiza zokucubungula, ngokugxila okuyinhloko ekuthuthukiseni ukuthuthukiswa kokuncibilika kwamanzi kanye nokuthuthukisa ukuzinza okushisayo kwezinto zokusetshenziswa. Uma kunesidingo, izinto zefomula zingaxutshwa kuqala, futhi amasampula amancane angathathwa ayohlolwa. Uma ingekho into esobala yokushintsha umbala noma ukuwohloka ebhokisini lempahla engu-230 ℃ amahora ama-2, kukhombisa ukuthi ukukhethwa kwezinto ezisizayo kunengqondo kakhulu.
2. Izinga lokushisa lenqubo yokubumba ye-extrusion yezinto ezifakwe nge-chlorinated polyvinyl chloride liphakeme kancane kunalelo lamapayipi e-PVC. Kodwa kufanele kuqashelwe ukuthi ukushintshashintsha kwezinga lokushisa akukwazi ukudlula ± 5 ℃.
3. Ngesikhathi sokukhiqizwa kwamapayipi e-CPVC, uma kukhona ukuphuma kwamandla, ukungasebenzi kahle kwemishini, izimpawu zokubola kwezinto ezincibilikayo, noma umusi ophuma emlonyeni wesikhunta, ukunikezwa kwezinto emgqonyeni womshini kufanele kumiswe ngokushesha. I-PVC resin kufanele isetshenziselwe ukususa izinto ezincibilikayo ze-CPVC emgqonyeni womshini kanye nesikhunta, bese umshini kufanele umiswe ukuze uxazulule inkinga.
4. Ngaphambi kokuthi inhlaka ifakwe ekukhiqizweni, kumele yomiswe futhi iphathwe ebhokisini lokuhlinzeka elingu-80 ℃ amahora angu-2-4. Uma kunesidingo, izinto ezisetshenziswayo ezixubene ngesivinini esiphezulu kufanele futhi zihlungwe ngesisefo se-mesh engu-40 kanye, bese zifakwa ku-extruder hopper ukuze zikhiqize.
5. Igesi ye-HCl ekhishwe ngesikhathi sokubola kwe-CPVC iyancibilika iyingozi empilweni yomuntu, futhi kufanele kuqashelwe ekungeneni komoya endaweni yokusebenzela yokukhiqiza.
6. Umgqomo womshini wokukhipha i-extrusion, isikulufu, nezinto ezincibilikisiwe ezigeleza ekubunjweni okubunjwayo okusetshenziselwa ukukhiqiza inhlaka ye-CPVC kufanele yenzelwe ukwelashwa okulwa nokugqwala ukuze kunwetshwe impilo yesevisi yezingxenye zemishini.
Enqubweni yangempela yokukhiqiza, inqubo yokubumba i-extrusion ye-polyvinyl chloride ene-chloride isenzima kakhulu. Yebo, kubalulekile ukukhetha umkhiqizo ofanele lapho usetshenziswa ezimweni ezithile, futhi sidinga ukucabangela ngokucophelela umthamo womkhiqizo ukuze kube lula ukusetshenziswa okuphumelelayo.
