Intshayelelo:
Kwimveliso kunye nokulungiswa kofakelo lwemibhobho yePVC, ukhetho lwezongezo ludlala indima ebalulekileyo ekumiseleni umgangatho kunye nokusebenza kwemveliso yokugqibela.Izongezo ezibini ezisetyenziswa ngokuqhelekileyo kwi-PVC processing yi-organic tin formulations kunye ne-calcium-zinc formulations.Kweli nqaku, siza kuthelekisa iingenelo kunye nokungonakali kwezi zilungiso zimbini kumxholo wokuvelisa iigranule zePVC eziqinileyo zokufakelwa kombhobho wePVC osezantsi.
Ukwenziwa kweTin ye-Organic:
Ukwenziwa kwetoti ye-Organic ibhekisa kusetyenziso lwezikhompawundi esekwe kwitoti ephilayo njengezizinzisi zobushushu kunye nezithambiso kwimveliso yePVC.Olu qulunqo lusetyenziswe ngokubanzi kwi-PVC processing ngenxa yozinzo olubalaseleyo lobushushu kunye neempawu zokuthambisa.
Ezinye zeengenelo zokwenziwa kwetoti ye-organic kwimveliso yofakelo lwemibhobho yePVC ziquka:
I-1.Ukuzinza kobushushu obuphuculweyo: I-Organic tin compounds isebenza njengezinzisi zokushisa ezisebenzayo, ukukhusela ukuthotywa kwe-thermal ye-PVC ngexesha lokucubungula.Oku kubangela ukuphuculwa kokusebenza kokusebenza kunye nokunciphisa amathuba okuba neziphene ezinxulumene nokuthotywa kwemveliso yokugqibela.
I-2.I-lubrication ephezulu: I-Organic tin compounds ibonisa iimpawu ezibalaseleyo zokuthambisa, eziququzelela ukuhamba kwe-PVC yokunyibilika ngexesha lokucubungula.Oku kukhokelela ekuzalisweni kwesikhunta esingcono kunye nokuphuculwa komgangatho ophuculweyo wokufakelwa kombhobho wePVC.
Ngakolunye uhlangothi, kukho izinto ezingalunganga ezihambelana nokusetyenziswa kwe-organic tin formulation, kuquka:
1.Iinkxalabo zokusingqongileyo: Ezinye iikhompawundi ze-organic tin, ezifana ne-organotins, zaziwa njengetyhefu kwaye ziyingozi kwimo engqongileyo.Ukusetyenziswa kwabo kuye kwalawulwa okanye kwavalwa kwimimandla ethile ngenxa yeengozi zendalo kunye nempilo.
I-2.Ixabiso: Iikhompawundi ze-tin ze-Organic zinokubiza kakhulu xa kuthelekiswa nolunye uqulunqo lwe-stabilizer, ukunyusa ixabiso lemveliso ye-PVC yokufakelwa kwemibhobho.
I-Calcium-Zinc Formation PVC Compound:
Ukuqulunqwa kwe-calcium-zinc, njengoko igama libonisa, kubandakanya ukusetyenziswa kwe-calcium kunye neetyuwa ze-zinc njengezinzisi zokushisa kwi-PVC processing.Olu qulunqo lunikeza enye indlela kwiikhompawundi ze-organic tin kwaye sele ifumene ukuthandwa kwiminyaka yakutshanje.Iinzuzo zecalciukwakhiwa kwe-um-zinc kwimveliso yokufakelwa kombhobho wePVC kubandakanya:
I-1.Iprofayili ephuculweyo yendalo: Iikhompawundi ze-calcium-zinc ngokuqhelekileyo zibhekwa njengento ehambelanayo nendalo xa kuthelekiswa ne-organic tin compounds.Banelo elisezantsi kwixicity kunye nokubeka imingcipheko embalwa kwimpilo yabantu kunye nokusingqongileyo.
2.Indleko-ngempumelelo: CalciuI-m-zinc formulations idla ngokuba yindleko ngakumbi kune-organic tin formulations.Oku kunokunceda ukunciphisa iindleko zemveliso yokufakelwa kwemibhobho yePVC kwaye kubenze bakhuphisane ngakumbi kwiimarike.
Nangona kunjalo, i-calcium-zinc formulatiKwakhona kukho iingxaki ezimbalwa:
I-1.Ukulinganiselwa kokuzinza kobushushu: I-calcium-zinc stabilizers ayinako ukunika umgangatho ofanayo wokuzinza kobushushu njengama-organic tin compounds.Ngenxa yoko, kunokubakho umngcipheko ophezulu wokuthotywa kwe-thermal ngexesha leprocessing, enokuchaphazela umgangatho wofakelo lombhobho wePVC.
2.Imiceli mngeni yokucubungula: Iimpawu zokuthambisa i-calcium-zinc stabilizers zisenokungasebenzi njengezo ze-organic tin compounds.Oku kunokukhokelela kwimiceli mngeni ekuzalisweni komngundo kwaye okunokuthi kube nempembelelo kumphezulu wokugqiba kunye nokuchaneka komda weemveliso zokugqibela.

Isiphelo:
Xa ukhetha phakathi kokuqulunqwa kwe-organic tin kunye nokwakhiwa kwe-calcium-zinc ukwenzela ukuveliswa kweegranule ze-PVC eziqinileyo kwi-PVC yokufakelwa kombhobho wokucubungula, kubalulekile ukuqwalasela iimfuno ezithile, ukuqwalaselwa kweendleko, kunye neenkxalabo zokusingqongileyo.Ukwenziwa kwetoti ephilayo kunika uzinzo olongezelelekileyo lobushushu kunye nokuthambisa okugqwesileyo kodwa kuneempembelelo zokusingqongileyo kunye neendleko.Ukuqulunqwa kwe-calcium-zinc kunika inketho ehambelana nokusingqongileyo kunye neendleko ezifanelekileyo kodwa kunokuba nemida malunga nokuzinza kobushushu kunye nemingeni yokucubungula.Ekugqibeleni, ukhetho lokuqulunqwa luxhomekeke kwiimfuno ezithile kunye nezinto eziphambili zomenzi.
