Ziziphi iingenelo kunye neengxaki zokongeza i-hydrotalcite kwi-calcium zinc stabilizers?

I-Hydrotalc yinto efunekayo kakhulu kwiziqinisi ze-calcium zinc. I-Hydrotalc inesakhiwo kunye neempawu zayo ezikhethekileyo, kwaye ezona mpawu zayo ziphambili yi-alkalinity kunye ne-multi porosity, kunye nokusebenza okugqwesileyo kunye nokusebenza kakuhle. Ingafunxa ngempumelelo i-hydrogen chloride ekhutshwa ngexesha lokuwohloka kwe-PVC, inciphise isantya se-hydrogen chloride ngokwayo kwi-resin ye-PVC, kwaye isebenze njenge-acid absorbent, eyaziwa ngokuba yi-thermal stabilizer. Isetyenziswa rhoqo njenge-thermal stabilizer.
IHydrotalc ikwanazo neengenelo zokucaca kakuhle, ukugquma, ukumelana nemozulu, kunye nokuqhubekeka nokusebenza. Ayingcoliswanga yi-sulfides, ayinatyhefu, kwaye ingasebenza ngokubambisana neziqinisi zobushushu ezifana nesepha ye-zinc kunye ne-organic tin. Luhlobo oluthembisayo kakhulu lwe-non-toxic assistant heat stabilizer.
Ulwakhiwo lwe-hydrotalcite luneeleyara ezinkulu phakathi kweeleyara eziyi-0.76-0.79nm, kwaye inendawo enkulu ethile yomphezulu, evumela amaqela ayo e-hydroxyl ukuba aphendule ngokupheleleyo kwi-hydrogen chloride kwaye inefuthe elihle kwizinzisi.
Iingxaki ze-hydrotalcite zezi:
1. Ngokuphathelele ubumhlophe bokuqala, i-hydrotalcite ayinampembelelo ekuphuculeni umbala wokuqala we-PVC nokuba iyodwa okanye ngokusebenzisana nenkqubo ye-calcium zinc. Emva kokuguga kwi-oven eshushu ye-180 ℃, umbala wesampuli udla ngokuba bomvu.
2. Ngokuphathelele ukuzinza kobushushu obomvu baseCongo, isenzo esinye se-hydrotalcite sinokuphucula ixesha lokuzinza kobushushu be-PVC, kwaye ngokwanda kobungakanani bokongeza, ixesha lokuzinza kobushushu be-PVC libonisa umkhwa okhulayo, kodwa ukwanda akubonakali kangako.
3. Xa kusetyenziswa indibaniselwano ye-hydrotalcite kunye nenkqubo ye-calcium zinc njengesizinzisi sobushushu, ixesha lozinzo lobushushu le-PVC liphucuka kakhulu, kwaye umkhwa wokwandisa ixesha lozinzo lobushushu kunye nokwanda kokongeza uyaneliswa. Ke ngoko, ii-dihydroxy metal hydroxides kufuneka zihlelwe njengezizinzisi zobushushu ezincedisayo zexesha elide, ezinokwandisa ngokufanelekileyo ixesha lozinzo lobushushu lexesha elide le-PVC. Ke ngoko, xa kuhlanganiswa izinzinzisi ze-calcium zinc, i-hydrotalcite yenye yezinto ezibalulekileyo ezisetyenzisiweyo.
