Ukwenziwa kwe-PVC kuhlala kujongana nemiba emibini engqongqo yomgangatho ephazamisa iinjineli zemveliso kunye nabaqulunqi: ukutshintsha kombala wemveliso okungalindelekanga kunye nokuna komphezulu. Iifektri ezininzi zichitha iiyure ezininzi zilungisa amaqondo obushushu okucubungula, ziguqula umlinganiselo wefomula, kwaye zitshintsha iibhetshi zezinto eziluhlaza, kodwa ukutyheli, iindawo ezimnyama, kunye nokuna kwempuphu emhlophe kusenzeka kwiimveliso ze-PVC ezigqityiweyo. Ezi ziphene azitshabalalisi nje kuphela inkangeleko yemveliso kunye nokucaca kwayo kodwa zikwakhokelela ekungahambelani kweebhetshi, ukunyuka kwamaxabiso enkunkuma, kunye namathuba oshishino alahlekileyo kwiiodolo zokwenza ngokwezifiso eziphezulu.
Uninzi lwamaqela emveliso aluyihoyi imbangela eyintloko: ukulandelela ukungcola kwizinga eliphantsiIziqinisi zePVCNgelixa iziqinisi ezisemgangathweni zibonelela ngokhuseleko olusisiseko lobushushu ngexesha lokukhupha kunye nokubumba, ukungcola okushiyekileyo kubangela iimpendulo ezingabonakaliyo zokubola kwe-catalytic ezonakalisa izakhiwo zeemolekyuli ze-PVC ngokuhamba kwexesha.Iziqinisi zePVC ezicocekileyo kakhulu, kuquka i-premium CaZn, i-BaZn, kunye ne-methyl tin variants, zisombulula ezi ngxaki ziphambili ngokunciphisa umxholo wokungcola, ukuzinzisa ukucutshungulwa kobushushu, kunye nokugcina umbala uhambelana ixesha elide kuzo zonke iintlobo zeemveliso ze-PVC.
Unxibelelwano olufihlakeleyo phakathi kokungcola kwe-Stabilizer kunye nokuwohloka komgangatho we-PVC
I-Polyvinyl chloride (PVC) ayizinzisi kakuhle kubushushu. Phantsi kweemeko zokucubungula ubushushu obuphezulu ezifunekayo ukuze kufakwe i-molding kunye ne-extrusion, i-PVC engatshintshwanga idlula kwi-molecular chain fracture kunye ne-thermal decomposition, nto leyo ebangela ukuba i-fading and be yellow. Iziqinisi zobushushu zongezwa ukuze zithintele izinto ezibangela ukubola kwaye zivale uzinzo lwemveliso ngexesha lemveliso kunye nobomi benkonzo yexesha elide.
Umahluko ophambili phakathi kwezinto ezizinzisayo eziqhelekileyo nezicocekileyo kakhulu usekwe kwizinto ezisele zishiyekile. Izinto ezizinzisayo eziqhelekileyo ezingabizi kakhulu ziqulathe ii-free acids ezingasuswanga, ii-heavy metal residues, kunye nee-organic discharge particles. Ezi zinto zingcolisayo ezincinci azibangeli monakalo ubonakalayo kwangoko emva kokuveliswa. Endaweni yoko, zisebenza njengee-catalysts ezisebenza kakhulu eziqhubeka nokukhawulezisa ukonakala kobushushu be-PVC ngexesha lokucubungula nokusetyenziswa kwemihla ngemihla.
Olu hlobo lokusabela olubangela iingxaki luvelisa izinto ezintathu eziqhelekileyo kwimveliso enkulu. Okokuqala, ukutshintsha kombala okuqhubekayo, kubandakanya ukutyheli ngokubanzi kunye nokuphambuka kombala wendawo phakathi kweebhetshi zemveliso. Okwesibini, ukuna kwamanzi kumphezulu, apho iikhompawundi zokungcola ezingaphendulwanga zifudukela ngaphandle ukuze zenze umgubo omhlophe okanye iifilimu ezimfiliba, zitshabalalisa ukukhanya komphezulu kunye nokucaca. Okwesithathu, ukusilela kokwaluphala ngokukhawuleza, okwenza iimveliso zePVC zibe buthathaka kwaye ziphelelwe ngumbala phantsi kokukhanya kwangaphandle kunye neendawo ezinomswakama ophezulu. Ngokungafaniyo neempazamo zokucubungula ezihlengahlengiswayo, ezi ziphene ezivela kukungcola zihlala zihleli kwaye azinakulungiswa ngonyango lwasemva kokuveliswa.
