Izinto eziluncedo kunye nokungonakali kwe-calcium zinc stabilizers

Ngexesha lenkqubo yeplastiki, i-calcium zinc stabilizers ine-electronegativity ephezulu, kwaye iindawo ezibukhali ze-PVC resin zinobudlelwane obuthile, zenza ii-complexes zamandla ebhondi eyomeleleyo.
Izizinzi ze-calcium zinc zinokwahlulwa zibe zizinzisi ze-calcium zinc eziqinileyo kunye nezinzinzi ze-calcium zinc.
I-Liquid calcium zinc stabilizer iyahambelana ne-resins kunye ne-plasticizers, kunye nokubonakala kakuhle, imvula ephantsi, idosi ephantsi, kunye nokusetyenziswa lula. Izinto ezingalunganga eziphambili kukungatyebi kakuhle kunye nokonakala ngexesha lokugcinwa kwexesha elide.
Izizinzi ze-calcium zinc eziqinileyo zenziwa ikakhulu ngesepha ye-stearic acid. Imveliso ibonakaliswe ngokuthambisa okulungileyo kwaye ifanelekile ukucubungula imibhobho ye-PVC enzima kunye neeprofayili
Iimveliso ezicutshungulwayo kusetyenziswa itekhnoloji ye-microemulsification yoyisa ezi ntsilelo zikhankanywe ngasentla. Gxininisa ekuphuculeni ukusuka kwimiba emibini: ukutshintsha umbala wokuqala, usebenzisa isixa esaneleyo sesepha ye-zinc, kunye nokusebenzisa i-arhente edibeneyo ukunika i-zinc chloride engenabungozi, eba yi-zinc complex complex; Ukunciphisa inani lesepha ye-zinc ukukhusela ukutsha kwe-zinc kunye nokutshintsha umbala wokuqala kunye nezongezo kwaziwa ngokuba yi-zinc ephantsi yokuxuba. Ayisetyenziswa ngokubanzi kuphela kwiimveliso ezithambileyo, kodwa nakwinkqubo yeemveliso ezinzima.
I-calcium zinc stabilizers, ngenxa ye-electronegativity ephezulu, inobudlelwane obuthile be-acute nodes ye-PVC resin ngexesha lenkqubo ye-plasticization, yenze i-complexes yamandla e-bond eyomeleleyo eyenza buthathaka okanye isombulule umtsalane weebhondi ze-ion kwiileya ezahlukeneyo ze-PVC. Oku kwenza ukuba amacandelo adibeneyo e-PVC asasazeke ngokulula, kwaye amaqela e-molecular axhomekeke kwimida emincinci, enenzuzo kwi-plasticization ye-PVC resin. Ukubangela ukunyuka okubukhali kwixinzelelo lokunyibilika, ukunyibilika
I-viscosity yomzimba iyancipha, ubushushu buyanda, kwaye ukushisa kweplastiki kuyancipha.
Ukongeza, njengoko izixhobo zokulungisa zePVC zemveli zenzelwe ukusetyenzwa kusetyenziswa i-lead stabilizers, nangona i-lubricant eyaneleyo yongeziweyo, ayinakunqanda i-resin ukuba iqhubele phambili iplastiki ngexesha elaneleyo, iphazamise ibhalansi yokuqala yokuthambisa. Kwinqanaba lamva lokusetyenziswa, i-PVC inyibilika idla isixa esikhulu sokuzinzisa ubushushu kwinqanaba le-homogenization, kodwa kwangaxeshanye ayinakufezekisa i-viscosity efanelekileyo kunye ne-elasticity ukuhlangabezana neemfuno zemveliso ye-PVC enzima.
