Lapho ukhetha okufanelekileI-PVC stabilizer yesikhumba sokwenziwa, izici ezimbalwa ezihlobene nezidingo ezithile zesikhumba sokwenziwa zidinga ukucatshangelwa. Nawa amaphuzu abalulekile:
1. Izidingo Zokusimama Okushisayo
Icubungula izinga lokushisa:Isikhumba sokwenziwa sivame ukucutshungulwa emazingeni okushisa aphezulu. Iziqinisi ze-PVC kumele zikwazi ukuvimbela ukuwohloka kwe-PVC kulawa mazinga okushisa. Isibonelo, enqubweni ye-calendering, izinga lokushisa lingafinyelela ku-160 - 180 ° C. I-Metal-based stabilizers iyathandai-calcium - zincfuthii-barium - i-zinc stabilizersizinqumo ezinhle njengoba zingabamba ngempumelelo i-hydrogen chloride ekhishwe ngesikhathi sokucutshungulwa kwe-PVC, ngaleyo ndlela kuthuthukise ukuzinza kokushisa.
Ukumelana Nokushisa Kwesikhathi Eside:Uma isikhumba sokwenziwa sihloselwe ukusetshenziswa lapho sizochayeka emazingeni okushisa aphakeme isikhathi eside, njengangaphakathi kwezimoto, khona-ke kudingeka iziqinisi ezinokumelana nokushisa okuhle kakhulu kwesikhathi eside. Ama-Organic tin stabilizer ayaziwa ngokuzinza kwawo okushisayo okuvelele futhi afanele izimo ezinjalo, nakuba zibiza kakhulu.
2. Izidingo Zokuqina Kombala
Ukuvimbela Ukuphuzi:Ezinye izikhumba zokwenziwa, ikakhulukazi lezo ezinemibala ekhanyayo, zidinga ukulawula okuqinile kokushintsha kombala. I-stabilizer kufanele ibe nezindawo ezinhle zokulwa nokuphuzi. Ngokwesibonelo,i-liquid barium - i-zinc stabilizersngama-phosphite ekhwalithi ephezulu angasiza ekuvimbeleni ukuphuzi ngokukhipha ngokuphumelelayo ama-radicals mahhala futhi avimbele ukusabela kwe-oxidation. Ngaphezu kwalokho, ama-antioxidants angengezwa ohlelweni lokuqiniswa ukuze kuthuthukiswe ukuzinza kombala.
Ukungafihli kanye Nokuhlanzeka Kombala:Ngezikhumba zokwenziwa ezisobala noma ezi-semi-transparent, i-stabilizer akufanele ithinte ukucaca nokuhlanzeka kombala wento. Iziqinisi ze-Organic tin zikhethwa kulokhu ngoba azihlinzeki nje ngokuzinza okuhle kakhulu kokushisa kodwa futhi zigcina ukucaca kwe-matrix ye-PVC.
3. Izidingo Zezakhiwo Zemishini
Ukuvumelana nezimo namandla okuqina:Isikhumba sokwenziwa sidinga ukuguquguquka okuhle namandla aqinile. Ama-Stabilizer akufanele abe nomthelela omubi kulezi zakhiwo. Amanye ama-stabilizer, njengensimbi - insipho - based stabilizers, angakwazi futhi ukusebenza njengama-lubricant, okusiza ukuthuthukisa ukusebenza kokucubungula kwe-PVC nokugcina izakhiwo zemishini zomkhiqizo wokugcina.
I-Wear Resistance:Kuzinhlelo zokusebenza lapho isikhumba sokwenziwa singaphansi kokungqubuzana nokuguga okuvamile, njengefenisha nempahla, isizinzisi kufanele sikwazi ukusebenza ngokuhambisana nezinye izithasiselo ukuze kuthuthukiswe ukumelana nokugqokwa kwento. Isibonelo, ngokungeza ama-fillers athile nama-plasticizers kanye ne-stabilizer, ukuqina kobuso nokumelana nokugqoka kwesikhumba sokwenziwa kungathuthukiswa.
4. Izidingo Zemvelo Nezempilo
Ubuthi:Ngokugcizelelwa okwandayo ekuvikelweni kwemvelo kanye nempilo yabantu, iziqinisi ezingenabo ubuthi zidingeka kakhulu. Esikhumbeni sokwenziwa esisetshenziswa ezintweni ezifana nemikhiqizo yezingane nezimpahla zokugqoka, izinto ezisindayo - zensimbi - zamahhala ezifana ne-calcium - zinc nezinzinzisi zomhlaba ezingandile zibalulekile. Lezi zinzinzisi zihambisana nemithetho efanele yezemvelo nempilo.
I-Biodegradability:Kwezinye izimo, kukhona okuncanyelwayo kwezinzinzisi ezingaboli ukuze kuncishiswe umthelela wendawo. Nakuba okwamanje kunezinzinzisi ezimbalwa ezingaboli ngokuphelele ezitholakalayo, ucwaningo luyaqhubeka kule ndawo, futhi ezinye iziqinisi ezinokuwohloka kwemvelo ngokwengxenye ziyathuthukiswa futhi ziyahlolwa ukuze zisetshenziswe esikhumbeni sokwenziwa.
5. Izindleko Ukucatshangelwa
Izindleko Zokuqinisa:Izindleko zama-stabilizer zingahluka kakhulu. Nakuba izinzinzisi ezisezingeni eliphezulu ezifana nezinzinzisi ze-organic tin zinikeza izakhiwo ezinhle kakhulu, zibiza kakhulu. Ngokuphambene, i-calcium - i-zinc stabilizers inikeza ibhalansi enhle phakathi kokusebenza nezindleko futhi isetshenziswa kabanzi embonini yesikhumba yokwenziwa. Abakhiqizi kudingeka bacabangele izindleko zabo zokukhiqiza kanye nentengo yemakethe yemikhiqizo yabo lapho bekhetha izinto zokuzinzisa.
Izindleko Zizonke - ukusebenza kahle:Akuyona nje izindleko ze-stabilizer ngokwayo ezibalulekile, kodwa futhi nezindleko zayo zonke - ukusebenza kahle. I-stabilizer ebiza kakhulu edinga umthamo ophansi ukuze kuzuzwe izinga elifanayo lokusebenza njengento eshibhile ingase empeleni ibe yindleko enkulu - isebenze ngokuhamba kwesikhathi. Ukwengeza, izici ezifana namazinga ancishisiwe okulahlwa kanye nekhwalithi yomkhiqizo ethuthukisiwe ngenxa yokusetshenziswa kwesiqinisi esithile kufanele kucatshangelwe lapho kuhlolwa izindleko - ukusebenza kahle.
Sengiphetha, ukukhetha isizinzisi se-PVC esifanele sesikhumba sokwenziwa kudinga ukucatshangelwa okuphelele kwezinto ezihlukahlukene, okuhlanganisa ukuqina kokushisa nombala, izakhiwo zemishini, izidingo zemvelo nempilo, kanye nezindleko. Ngokuhlola ngokucophelela lezi zici nokwenza izivivinyo nokuhlola, abakhiqizi bangakhetha isizinzisi esifaneleka kakhulu ukuze bahlangabezane nezidingo ezithile zemikhiqizo yabo yesikhumba yokwenziwa.
I-TOPJOY ChemicalInkampani ibilokhu izibophezele ocwaningweni, ekuthuthukisweni, nasekukhiqizweni kwemikhiqizo yokuqiniswa kwe-PVC esebenza kahle kakhulu. Ithimba lochwepheshe le-R&D le-Topjoy Chemical Company liqhubeka nokuqamba izinto ezintsha, lithuthukisa ukwakheka kwemikhiqizo ngokwezidingo zemakethe kanye namathrendi okuthuthukisa imboni, futhi linikeza izixazululo ezingcono zamabhizinisi okukhiqiza. Uma ufuna ukufunda ulwazi olwengeziwe mayelana nezinzinzisi ze-PVC, wamukelekile ukusithinta nganoma yisiphi isikhathi!
