Isiqinisi sobushushu esihlanganisiweyo
Isiqinisi sobushushu esihlanganisiweyo
Iziqinisi zetyuwa yelead azinazo nje kuphela uzinzo oluhle lobushushu kwaye zingasetyenziswa njenge-PVC stabilizer ephambili kwiimveliso zePVC, kodwa zikwanazo neempawu zazo ezizimeleyo, ekufuneka ziqwalaselwe xa uzisebenzisa. Ngokweminyaka emininzi yamava oyilo lwefomula, amanqaku ekufuneka aqwalaselwe xa usebenzisa i-monomeric lead salt stabilizers ashwankathelwe ngolu hlobo lulandelayo:
1. Ziqonde ngokupheleleyo iimpawu kunye neemeko zokusetyenziswa kwe-lead salt composite stabilizer nganye, uze uyivavanye kwaye uyilungise ngokusebenzayo.
Isiqinisi ngasinye setyuwa ye-lead sineempawu zaso ezizimeleyo kunye noluhlu lwesicelo. Ukuba sifuna ukusebenzisa isiqinisi kakuhle, kufuneka siziqonde ngokupheleleyo iimpawu zaso, sazi ukuba singabonisa phantsi kweziphi iimeko izibonelelo zaso, kwaye phantsi kweziphi iimeko iimeko ezingafanelekanga ukusetyenziswa. Umzekelo, i-dibasic lead phosphite inokumelana okuhle kwemozulu, kwaye izibonelelo zayo zingasetyenziswa ngokupheleleyo kwiimveliso zangaphandle ezigxininisa ukumelana nemozulu, ngoko ke ihlala isebenza njengesiqinisi esiphambili kwiimveliso ezinjalo, ngelixa i-tribasic lead sulfate inokusebenza okuhle kozinzo lobushushu, ingasetyenziswa njengesiqinisi esiphambili kwimeko efuna uzinzo oluphezulu lobushushu.
2. Khetha isizinzisi esifanelekileyo ngokwemiqathango ethile yokucubungula kunye nesicelo
Iimveliso ezahlukeneyo zineemfuno ezahlukeneyo, kwaye kufuneka kukhethwe iziqinisi ezahlukeneyo. Izixhobo ezahlukeneyo kunye neemeko zokucubungula zineemfuno ezahlukeneyo zeziqinisi. Siqwalasela ngononophelo iimeko ezithile zokusetyenziswa kuyilo lwefomyula kwaye sikhethe uhlobo olufanelekileyo lwesiqinisi kunye nokudibanisa. Umlinganiselo. Phakathi kweemveliso eziphambili, imibhobho ngokubanzi ayifuni ukumelana nemozulu ephezulu, ngoko ke i-tribasic lead sulfate enozinzo oluhle lobushushu isetyenziswa kakhulu njengesiqinisi esiphambili. Ukongeza, ngenxa yesimo esilula se-cross-sectional yombhobho kunye nembali emfutshane yobushushu ngexesha lokucubungula, ubungakanani besiqinisi abubukhulu kakhulu.
3. Isiphumo sokusebenzisana phakathi kwezinzisi
Kukho iziphumo ezintathu ezahlukeneyo zokudibanisa izinto ezizinzisayo: enye yimpembelelo ye-synergistic, eyimpembelelo ye-1+1>2; enye yimpembelelo yokongeza, eyimpembelelo ye-1+1=2; enye yimpembelelo echaseneyo, eyimpembelelo ye-1+1<2. Kufuneka siqonde ngononophelo ukusebenzisana phakathi kwezinto ezizinzisayo ezahlukeneyo xa sisenza uyilo, sisebenzise ngakumbi impembelelo ye-synergistic phakathi kwezinto ezizinzisayo, kwaye sizame konke okusemandleni ethu ukunqanda impembelelo yokujongana phakathi kwezinto ezizinzisayo, ukuze sifumane inkqubo ye-heat stabilizer engabizi kakhulu.
1. Ixabiso eliphantsi lezinto ezizinzisa ityuwa yelead lelona xabiso liphantsi kuzo zonke izinto ezizinzisa, ngoko ke nangona kuqaliswa rhoqo izinto ezintsha ezizinzisa ityuwa yelead, izinto ezizinzisa ityuwa yelead zisasebenza kwimarike ebalaseleyo yezinto ezizinzisa emva kwesiqingatha senkulungwane;
2. Ubuthi bezinto ezigcina ityuwa yelead inetyhefu buthintela ukusetyenziswa kwayo kwiimeko ezininzi ngemiqathango engqongqo yococeko;
3, ukusasazeka kakubi kwetyuwa ukusasazeka kakubi, kodwa iimveliso ezisandula ukuqaliswa ezinezithambiso, ukusuka kwinqanaba elithile ukusombulula ingxaki yokusasazeka
1. Kuphucule kakhulu ukufana kokuxuba nokusasaza nge-resin;
2. Ukudibanisa ukuthambisa ngaphakathi nangaphandle okufanelekileyo nokufanelekileyo;
3. Inceda ekuveliseni nasekulawuleni umgangatho;
4. Xa ifomula ixutyiwe, inani lamaxesha okulinganisa lenziwa lula.
