Kuyerekeza Kusiyana Kwakukulu Pakati pa PVC Calcium Zinc Stabilizers ndi Lead Salt Stabilizers:
1, Ubwino wa chilengedwe ndi poizoni
1. Chokhazikitsa calcium zinc
Yopanda zitsulo zolemera monga lead ndi cadmium, mogwirizana ndi miyezo ya EU RoHS/REACH yokhudza chilengedwe;
Yovomerezeka ndi FDA, yoyenera kugwiritsidwa ntchito m'magawo otetezedwa ndi chitetezo monga ma CD ndi zida zachipatala.
2. Chokhazikitsa mchere wa lead
Pokhala ndi lead yachitsulo cholemera, fumbi la poizoni limapangidwa panthawi yokonza, ndipo kuwonetsedwa kwa nthawi yayitali kungawononge thanzi la anthu;
Zinthu zotayidwa zimatha kuyambitsa kuipitsa nthaka ndi madzi mosavuta.
2, njira yokhazikika ya kutentha
1. Chokhazikitsa calcium zinc
Kudzera mu njira yokonzanso magawo awiri: sopo wa zinc amalowa m'malo mwa maatomu osakhazikika a chlorine, sopo wa calcium amabwezeretsa sopo wa zinc kuti awonjezere nthawi yokhazikika;
Ndikofunikira kugwiritsa ntchito ma synergists monga β - diketone ndi hydrotalcite kuti muwonjezere kukhazikika (ndi kuchuluka kowonjezera kwa 0.3% -2%).
2. Chokhazikitsa mchere wa lead
Kupanga mwachindunji zovuta ndi mamolekyu a PVC, kuletsa bwino momwe HCl imachotsera unyolo;
Chigawo chimodzi chingathe kukhala ndi kukhazikika kwa kutentha kwa nthawi yayitali popanda kufunikira kwa machitidwe ovuta a mgwirizano.
3, Processing magwiridwe antchito
| Zinthu zoyerekeza | Chokhazikika cha zinki ya calcium | 铅盐稳定剂 |
| Lubricity | Kuwongolera molondola kuchuluka kwa mafuta ofunikira (kuchuluka kwambiri kumatha kugwa mvula) | Imabwera ndi mawonekedwe a mafuta odzola komanso zenera lalikulu lokonzekera |
| kulamulira mtundu | Chogulitsachi chimakhala ndi mtundu wa buluu ndipo chikufunika kukonzedwa powonjezera toner. | Kukhazikika kwa mitundu komanso kusinthasintha pang'ono pakati pa magulu |
| Kusungunuka kwa madzi | Chepetsani kutentha kwa pulasitiki ndi 5-10 ℃ | Sizimakhudza kwambiri kukhuthala kwa kusungunuka |
4, zoletsa zochitika za ntchito
1. Chokhazikitsa calcium zinc
Zinthu zowonekera bwino ziyenera kuwonjezera hypophosphite (0.5%) kuti ziwongolere kuwonekera bwino;
Makina odzaza kwambiri (calcium carbonate> 30phr) amatha kuvutika ndi chisanu.
2. Chokhazikitsa mchere wa lead
◉ Imagwira ntchito pazinthu zosawoneka bwino (monga mapaipi ndi ma profiles);
Malo okhala ndi sulfure kumpoto angapangitse kuti pamwamba pa zinthuzo pakhale sulfure ndikuda mosavuta.
5, kusiyana kwachuma
Kuchuluka kwa calcium zinc stabilizer ndi kotsika ndi 40%, zomwe zingawonjezere kuchuluka kwa zodzaza ndikuchepetsa ndalama;
Mtengo wa unit wa lead salt stabilizers ndi wotsika, koma ndalama zowonjezera zochizira heavy metal ziyenera kulipidwa;
Kuyerekeza zinthu zambiri, zitha kuwoneka kuti zokhazikika za calcium zinc zili ndi ubwino waukulu pakusinthasintha kwa chilengedwe, pomwe zokhazikika za mchere wa lead zimasungabe phindu lenileni pakupirira kukonza ndi kuwongolera ndalama.
