Ngexesha lenkqubo yokwenza iplastiki, iziqinisi ze-calcium zinc zine-electronegativity ephezulu, kwaye amaqhuqhuva e-PVC resin anobuhlobo obuthile, enza ii-complexes zamandla ezibophelelayo.
Iziqinisi ze-calcium zinc zinokwahlulwa zibe ziziqinisi ze-calcium zinc eziqinileyo kunye neziqinisi ze-calcium zinc ezingamanzi
I-calcium zinc stabilizer engamanzi iyahambelana neeresini kunye neeplastiki, icacile kakuhle, inemvula encinci, idosi ephantsi, kwaye kulula ukuyisebenzisa. Izinto ezingalunganga kakhulu kukuthambisa okungekho semgangathweni kunye nokonakala ngexesha lokugcina ixesha elide.
Iziqinisi ze-calcium zinc eziqinileyo zenziwe kakhulu ngesepha ye-stearic acid. Le mveliso iphawuleka ngokuthambisa okuhle kwaye ifanelekile ekucutshungulweni kwemibhobho ye-PVC eqinileyo kunye neeprofayili
Iimveliso ezicutshungulwa kusetyenziswa iteknoloji ye-microemulsification ziyazoyisa ezi ngxaki zikhankanyiweyo apha ngasentla. Gxila ekuphuculeni ukusuka kwiinkalo ezimbini: ukutshintsha umbala wokuqala, ukusebenzisa isixa esaneleyo sesepha ye-zinc, kunye nokusebenzisa i-composite agent ukwenza i-zinc chloride ingabi nabungozi, nto leyo eba yi-zinc complex ephezulu; Ukunciphisa isixa sesepha ye-zinc ukuthintela ukutsha kwe-zinc kunye nokutshintsha umbala wokuqala ngee-additives kwaziwa ngokuba yi-low zinc blending. Ayisetyenziswa kakhulu kwiimveliso ezithambileyo kuphela, kodwa ikwasetyenziswa nasekucutshungulweni kweemveliso eziqinileyo.
Iziqinisi ze-calcium zinc, ngenxa yokuba ziphezulu kwi-electronegativity, zinobuhlobo obuthile kwii-nodes ezibukhali ze-resin ye-PVC ngexesha lenkqubo yokwenza iplastiki, zenze ii-complexes zamandla ezibophelelayo ezibuthathaka okanye ezisombulula ukutsalana kwee-ion bonds kwiileya ezahlukeneyo ze-PVC. Oku kwenza ukuba iindawo ezidibeneyo ze-PVC zibe lula ukuzisasaza, kwaye amaqela eemolekyuli athambekele kwimida emincinci, nto leyo eluncedo ekwenzeni i-resin ye-PVC ibe yiplastiki. Oku kubangela ukwanda okukhulu koxinzelelo lokunyibilika, ukunyibilika
Ukuqina komzimba kuyehla, ubushushu buyanda, kwaye ubushushu bokwenza iplastiki buyancipha.
Ukongeza, njengoko izixhobo zesiqhelo zokucubungula i-PVC zenzelwe ukucubungula kusetyenziswa iziqinisi zetyuwa ye-lead, nokuba kufakwe i-lubricant eyaneleyo, ayinakuthintela i-resin ekubeni iqhubeke iplastiki ngexesha elaneleyo, nto leyo ephazamisa ibhalansi yokuthambisa yokuqala. Kwinqanaba lokugqibela lokusetyenziswa, i-PVC melt idla isixa esikhulu se-heat stabilizer kwinqanaba le-homogenization, kodwa kwangaxeshanye ayinakufikelela kwi-viscosity kunye ne-elasticity efanelekileyo ukuhlangabezana neemfuno zemveliso ye-PVC eqinileyo.
