Xa ukhetha into efanelekileyoI-PVC yokuzinzisa yesikhumba sokwenziwa, izinto ezininzi ezinxulumene neemfuno ezithile zesikhumba sokwenziwa kufuneka ziqwalaselwe. Nazi iingongoma eziphambili:
1. IiMfuno zokuZinza kweThermal
Ukulungiswa kobushushu:Isikhumba sokwenziwa sisoloko sisenziwa kumaqondo obushushu aphezulu. Izizinzi zePVC kufuneka zikwazi ukunqanda ukuthotywa kwePVC kula maqondo obushushu. Umzekelo, kwinkqubo yokulinganisa, amaqondo obushushu anokufikelela kwi-160 - 180°C. Metal-based stabilizers ezifanacalcium - zinckwayei-barium - i-zinc stabilizerslukhetho oluhle njengoko lunokuthi lubambe ngokufanelekileyo i-hydrogen chloride ekhutshwe ngexesha lokucubungula i-PVC, ngaloo ndlela iphucula ukuzinza kwe-thermal.
Ixesha elide lokuxhathisa ubushushu:Ukuba isikhumba sokwenziwa sijoliswe kwizicelo apho siya kubonakaliswa kwiqondo lokushisa eliphakamileyo ixesha elide, njengangaphakathi kwemoto, ngoko ke i-stabilizers enokumelana nokushisa kwexesha elide iyadingeka. I-Organic tin stabilizers iyaziwa ngokuzinza kwe-thermal ebalaseleyo kwaye ifanelekile kwiimeko ezinjalo, nangona zibiza kakhulu.
2. IiMfuno zokuZinza koMbala
Ukuthintelwa koMthubi:Ezinye izikhumba zokwenziwa, ngakumbi ezo zinemibala ekhanyayo, zifuna ulawulo olungqongqo lokutshintsha kombala. I-stabilizer kufuneka ibe neempawu ezintle zokulwa ne-yellowing. Njengokuba,i-liquid barium - i-zinc stabilizersnge-high-quality phosphites inokunceda ukuthintela ukutyheli ngokutshabalalisa ngokufanelekileyo ii-radicals zasimahla kunye nokuthintela ukuphendula kwe-oxidation. Ukongeza, i-antioxidants inokongezwa kwisistim sokuzinza ukuphucula uzinzo lombala.
Ukungafihli kunye nokucoceka koMbala:Kwizikhumba ezingabonakaliyo okanye ezicacileyo, i-stabilizer akufanele ichaphazele ukucaca kunye nokucoceka kombala wezinto eziphathekayo. I-Organic tin stabilizers zikhethwa kule meko kuba aziboneleli kuphela ukuzinza kwe-thermal kodwa zigcina ukucaca kwe-matrix ye-PVC.
3. IiMfuno zeePropati zoomatshini
Ukuguquguquka kunye namandla okuqina:Isikhumba sokwenziwa kufuneka sibe nokuguquguquka okuhle kunye namandla okuqina. Izinzisi akufanele zibe nefuthe elibi kwezi zakhiwo. Ezinye izizinzi, ezifana nesinyithi - isepha - i-stabilizers esekelwe, inokuphinda isebenze njengezinto zokuthambisa, ezinceda ukuphucula ukusebenza kwePVC kunye nokugcina iimpawu zomatshini zemveliso yokugqibela.
Nxiba Ukuxhathisa:Kwizicelo apho isikhumba sokwenziwa sixhomekeke kwingxabano rhoqo kunye nokugqoka, njengefenitshala kunye nempahla, i-stabilizer kufuneka ikwazi ukusebenza ngokubambisana nezinye izongezo zokuphucula ukuxhatshazwa kwezinto eziphathekayo. Ngokomzekelo, ngokongeza izihluzi ezithile kunye neeplastiki kunye ne-stabilizer, ukuqina komphezulu kunye nokumelana nokunxiba kwesikhumba sokwenziwa kunokwandiswa.
4. IiMfuno zokusiNgqongileyo nezeMpilo
Ubutyhefu:Ngokugxininiswa okukhulayo ekukhuselweni kwendalo kunye nempilo yabantu, izinzinzi ezingezizo zinetyhefu zifunwa kakhulu. Kwisikhumba sokwenziwa esisetyenziswa kwizinto ezifana neemveliso zabantwana kunye nempahla, i-heavy - metal - stabilizers yasimahla njenge-calcium - i-zinc kunye nezinqabileyo - izinzisi zomhlaba zibalulekile. Ezi zinzisi zihambelana nemithetho yendalo kunye nempilo efanelekileyo.
Ukonakala kwezinto eziphilayo:Kwezinye iimeko, kukho ukhetho lwezinzisi ze-biodegradable ukunciphisa impembelelo yokusingqongileyo. Nangona kungoku nje zimbalwa izizinzisi ezinokonakala ngokupheleleyo ezifumanekayo, uphando luyaqhuba kulo mmandla, kwaye ezinye izizinzisi ezinokonakala kwebhayoloji ngokuyinxenye ziyaphuhliswa kwaye zivavanyelwa ukusetyenziswa kwesikhumba sokwenziwa.
5. Ukuqwalaselwa kweendleko
Iindleko zokuZinzisa:Iindleko ze-stabilizers zinokuhluka kakhulu. Ngelixa izizinzisi eziphezulu zokusebenza njengezizinzisi ze-organic tin zibonelela ngeempawu ezibalaseleyo, zibiza kakhulu. Ngokwahlukileyo, i-calcium - i-zinc stabilizers inika ibhalansi elungileyo phakathi kokusebenza kunye neendleko kwaye isetyenziswa ngokubanzi kwishishini lesikhumba sokwenziwa. Abavelisi kufuneka bathathele ingqalelo iindleko zabo zemveliso kunye nexabiso lemarike yeemveliso zabo xa bekhetha izizinzisi.
Iindleko zizonke - ukusebenza kakuhle:Akunjalo nje ixabiso le-stabilizer ngokwayo elibalulekileyo, kodwa kunye neendleko zayo zonke - ukusebenza kakuhle. Uzinziso olubiza kakhulu olufuna idosi ephantsi ukuphumeza umgangatho ofanayo wokusebenza njengexabiso eliphantsi kunokuba ngenene ixabiso elithe chatha – elisebenzayo ekuhambeni kwexesha. Ukongezelela, izinto ezifana namazinga okuncitshiswa kwe-scrap kunye nokuphuculwa komgangatho wemveliso ngenxa yokusetyenziswa kwe-stabilizer ethile kufuneka ithathelwe ingqalelo xa kuhlolwa iindleko - ukusebenza kakuhle.
Ukuqukumbela, ukukhetha i-PVC yokuzinzisa echanekileyo yesikhumba sokwenziwa kufuna ingqwalasela ebanzi yezinto ezahlukeneyo, kubandakanywa ukuzinza kwe-thermal kunye nombala, iimpawu zoomatshini, iimfuno zokusingqongileyo kunye nempilo, kunye neendleko. Ngokuphonononga ngononophelo le miba kunye nokuqhuba iimvavanyo kunye neemvavanyo, abavelisi banokukhetha eyona nto ifanelekileyo yokuzinzisa ukuhlangabezana neemfuno ezithile zeemveliso zabo zesikhumba.
