Uma ukhetha inketho efanelekileIsiqinisi se-PVC sesikhumba sokwenziwa, izici eziningana ezihlobene nezidingo ezithile zesikhumba sokwenziwa zidinga ukucatshangelwa. Nazi amaphuzu abalulekile:
1. Izidingo Zokuzinza Kokushisa
Izinga Lokushisa Lokucubungula:Isikhumba sokwenziwa sivame ukucutshungulwa emazingeni okushisa aphezulu. Iziqinisi ze-PVC kumele zikwazi ukuvimbela ukuwohloka kwe-PVC kulawa mazinga okushisa. Isibonelo, enkambisweni yokulinganisa, amazinga okushisa angafinyelela ku-160 - 180°C. Iziqinisi ezisekelwe ensimbi ezifanai-calcium - i-zincfuthiiziqinisi ze-zinc ze-bariumkuyizinketho ezinhle njengoba zingabamba ngempumelelo i-hydrogen chloride ekhishwa ngesikhathi sokucubungula i-PVC, ngaleyo ndlela zithuthukise ukuzinza kokushisa.
Ukumelana Nokushisa Kwesikhathi Eside:Uma isikhumba sokwenziwa senzelwe ukusetshenziswa lapho sizovezwa khona emazingeni okushisa aphezulu isikhathi eside, njengangaphakathi kwezimoto, khona-ke kudingeka iziqinisi ezinokumelana nokushisa okuhle kakhulu isikhathi eside. Iziqinisi ze-organic tin zaziwa ngokuqina kwazo okuvelele kokushisa futhi zifanele izimo ezinjalo, yize zibiza kakhulu.
2. Izidingo Zokuzinza Kombala
Ukuvimbela Ukuphuzi:Ezinye izikhumba zokwenziwa, ikakhulukazi lezo ezinemibala ekhanyayo, zidinga ukulawulwa okuqinile kokushintsha kombala. Isiqinisi kufanele sibe nezakhiwo ezinhle zokulwa nokuphuzi. Isibonelo,iziqinisi ze-zinc ze-barium eziwuketsheziAma-phosphite asezingeni eliphezulu angasiza ekuvimbeleni ukuphuzi ngokuqeda ngempumelelo ama-free radicals nokuvimbela ukusabela kwe-oxidation. Ngaphezu kwalokho, ama-antioxidants angangezwa ohlelweni lokuzinza ukuze kuthuthukiswe ukuzinza kombala.
Ukucaca kanye nokuhlanzeka kombala:Kwezikhumba zokwenziwa ezisobala noma ezicishe zibe sobala, isiqinisi akufanele sithinte ukucaca kanye nobumsulwa bombala wezinto ezibonakalayo. Iziqinisi zethini lemvelo ziyathandwa kulokhu ngoba azigcini nje ngokuhlinzeka ngokuqina okuhle kokushisa kodwa futhi zigcina ukucaca kwe-matrix ye-PVC.
3. Izidingo Zezakhiwo Zemishini
Ukuzivumelanisa nezimo kanye namandla okuqina:Isikhumba sokwenziwa sidinga ukuguquguquka okuhle kanye namandla okuthamba. Ama-stabilizer akufanele abe nomthelela omubi kulezi zakhiwo. Ezinye izi-stabilizer, njengezi-stabilizer ezisekelwe ensimbini – insipho, zingasebenza futhi njengezinto zokugcoba, ezisiza ekuthuthukiseni ukusebenza kokucubungula kwe-PVC nokugcina izakhiwo zemishini zomkhiqizo wokugcina.
Ukumelana Nokugqoka:Ezisetshenzisweni lapho isikhumba sokwenziwa sivame ukungqubuzana nokuguguleka, njengasefenisha nasezingutsheni, isiqinisi kufanele sikwazi ukusebenza kanye nezinye izithasiselo ukuthuthukisa ukumelana nokuguguleka kwezinto. Isibonelo, ngokufaka ama-filler athile kanye nama-plasticizer kanye nesiqinisi, ubulukhuni bomphezulu kanye nokumelana nokuguguleka kwesikhumba sokwenziwa kungathuthukiswa.
4. Izidingo Zemvelo Nezempilo
Ubuthi:Njengoba kugcizelelwa kakhulu ukuvikelwa kwemvelo kanye nempilo yabantu, izinto zokuqinisa ezingezona ezinobuthi zidingeka kakhulu. Ngesikhumba sokwenziwa esisetshenziswa ezinhlotsheni ezifana nemikhiqizo yezingane kanye nezingubo, izinto zokuqinisa ezingenansimbi njenge-calcium, i-zinc kanye nezinto zokuqinisa umhlaba ezingavamile zibalulekile. Lezi zinto zokuqinisa zihambisana nemithethonqubo efanele yezemvelo kanye nempilo.
Ukubola kwe-biogradability:Kwezinye izimo, kunokukhetha iziqinisi ezibolayo ukuze kuncishiswe umthelela emvelweni. Nakuba okwamanje zimbalwa iziqinisi ezibolayo ngokuphelele ezitholakalayo, ucwaningo luyaqhubeka kule ndawo, futhi ezinye iziqinisi ezinokubola okungaphelele ziyathuthukiswa futhi zihlolwe ukuze zisetshenziswe esikhumbeni sokwenziwa.
5. Izindleko Zokucatshangelwa
Izindleko ze-Stabilizer:Izindleko zeziqinisi zingahluka kakhulu. Nakuba iziqinisi zokusebenza okuphezulu njengeziqinisi ze-tin eziphilayo zinikeza izakhiwo ezinhle kakhulu, zibiza kakhulu. Ngokuphambene nalokho, iziqinisi ze-calcium-zinc zinikeza ibhalansi enhle phakathi kokusebenza kanye nezindleko futhi zisetshenziswa kabanzi embonini yesikhumba sokwenziwa. Abakhiqizi kudingeka bacabangele izindleko zabo zokukhiqiza kanye nentengo yemakethe yemikhiqizo yabo lapho bekhetha iziqinisi.
Izindleko Eziphelele - ukusebenza kahle:Akuyona nje kuphela izindleko zesiqinisi uqobo ezibalulekile, kodwa futhi nokusebenza kahle kwezindleko zaso jikelele. Isiqinisi esibiza kakhulu esidinga umthamo ophansi ukuze sifinyelele izinga elifanayo lokusebenza njengeshibhile singase sibe nokusebenza kahle kakhulu ngokuhamba kwesikhathi. Ngaphezu kwalokho, izici ezifana namanani aphansi okunciphisa kanye nekhwalithi yomkhiqizo ethuthukisiwe ngenxa yokusebenzisa isiqinisi esithile kufanele zicatshangelwe lapho kuhlolwa ukusebenza kahle kwezindleko.
Ekuphetheni, ukukhetha isiqinisi se-PVC esifanele sesikhumba sokwenziwa kudinga ukucatshangelwa okubanzi kwezinto ezahlukahlukene, okuhlanganisa ukuqina kokushisa nombala, izakhiwo zemishini, izidingo zemvelo nezempilo, kanye nezindleko. Ngokuhlola ngokucophelela lezi zici nokwenza izivivinyo nokuhlolwa, abakhiqizi bangakhetha isiqinisi esifanele kakhulu ukuhlangabezana nezidingo ezithile zemikhiqizo yabo yesikhumba sokwenziwa.
