Abantu abaningi abajwayelene ne-polyethylene ene-chlorine, futhi njengoba igama lisho, abantu abaningi kufanele bakwazi ukubona kuphela ukuthi iyizinto zamakhemikhali. Inenqubo ebizwa ngokuthi i-extrusion molding, esabalulekile kakhulu enqubweni yokukhiqiza. Ngakho-ke namuhla, yini okufanele siyinake ngesikhathi senqubo yokubumba i-extrusion yalo mkhiqizo? I-polyvinyl chloride ene-chlorine
1. Efomini yezinto zokusetshenziswa zokwakha amapayipi, kufanele kuqashelwe ukukhethwa kwezinto zokuqinisa kanye nezinye izinsiza zokucubungula, kugxilwe kakhulu ekuthuthukiseni ukugeleza kokuncibilika kanye nokuthuthukisa ukuzinza kokushisa kwezinto zokusetshenziswa. Uma kudingeka, izinto zokusetshenziswa zingaxutshwa kuqala, bese amasampula amancane angathathwa ukuze ahlolwe. Uma kungekho sici esicacile sokushintsha kombala noma sokubola ebhokisini lokuphakelwa elingu-230 ℃ amahora ama-2, kubonisa ukuthi ukukhethwa kwezinto zokusetshenziswa ezisizayo kunengqondo kakhulu.
2. Izinga lokushisa lenqubo yokubumba i-extrusion yezinto ze-polyvinyl chloride ezifakwe i-chlorine liphakeme kancane kunelepayipi le-PVC. Kodwa kufanele kuqashelwe ukuthi ukushintshashintsha kokulawula izinga lokushisa akukwazi ukudlula ± 5 ℃.
3. Ngesikhathi sokukhiqizwa kwamapayipi e-CPVC, uma kukhona ukucima kukagesi, ukungasebenzi kahle kwemishini, izimpawu zokubola kwezinto ezincibilikayo, noma intuthu ephuma emlonyeni wesikhunta, ukunikezwa kwezinto eziya emgqonyeni womshini kufanele kumiswe ngokushesha. I-resin ye-PVC kufanele isetshenziswe ukususa izinto ezincibilikayo ze-CPVC emgqonyeni womshini kanye nesikhunta, bese umshini umiswa ukuze kuxazululwe inkinga.
4. Ngaphambi kokuba i-resin ifakwe ekukhiqizweni, kumele yomiswe futhi iphathwe ebhokisini lokunikeza elingu-80 ℃ amahora angu-2-4. Uma kudingeka, izinto zokusetshenziswa ezixutshwe ngesivinini esikhulu kufanele zihlungwe ngesihlungo se-mesh esingu-40 kanye, bese zifakwa ku-extruder hopper ukuze zikhiqizwe.
5. Igesi ye-HCl ekhishwa ngesikhathi sokubola kwe-CPVC incibilika iyingozi empilweni yabantu, futhi kufanele kunakwe ukungenisa umoya endaweni yokukhiqiza.
6. Umgqomo womshini wokukhipha, izikulufo, nezinto ezincibilikisiwe ezigeleza ngesikhunta sokubumba esisetshenziselwa ukukhiqiza i-resin ye-CPVC kumele ziphathwe ngendlela yokulwa nokugqwala ukuze kwandiswe impilo yenkonzo yezingxenye zemishini.
Enqubweni yokukhiqiza yangempela, inqubo yokubumba i-extrusion ye-polyvinyl chloride ene-chlorine isanzima impela. Yiqiniso, kubalulekile ukukhetha umkhiqizo ofanele uma uwusebenzisa ezimweni ezithile, futhi sidinga ukucabangela ngokucophelela umthamo womkhiqizo ukuze kube lula ukuwusebenzisa ngempumelelo.
