Kusiyana pakati pa calcium zinc stabilizer ndi lead salt stabilizer

1, Njira yogwirira ntchito
Chokhazikika cha zinki ya calcium: chimaletsa kuwonongeka kwa PVC kudzera mu mphamvu ya sopo ya calcium ndi sopo ya zinki, pomwe chimayamwa mpweya wa HCl wopangidwa ndi kuwonongeka kwa PVC. Kukhazikika kwake kumachokera ku mphamvu yophatikizana ya zinthu zingapo (monga rare earths, hydrotalcite, ndi zina zotero), zomwe zingalepheretse kuwonongeka kwa PVC ndi zinc ions.
Chokhazikika cha mchere wa lead: kudalira mphamvu ya Lewis acidity ya mchere wa lead kuti ichepetse HCl, ndikuletsa kusokonekera kwa unyolo wa PVC mwa kuchotsa maatomu osakhazikika a chlorine.
2、 Kukhazikika komanso kukhala wochezeka kwa chilengedwe
Kukhazikika:
Zolimbitsa mchere wa lead zimakhala ndi kutentha kokhazikika bwino, zokhala ndi utoto woyambirira, mafuta odzola, komanso kukana kwa nyengo kwa nthawi yayitali.
Kukhazikika koyambirira kwa zinthu zokhazikika za calcium zinc ndi kofooka, koma zinthu zopangidwa ndi zinthu monga rare earth calcium zinc zimathandizira kwambiri magwiridwe antchito kudzera mu mphamvu zogwirizana, zomwe zimafika pamlingo wa mchere wa lead.
Ubwino wa chilengedwe:
Mchere wa lead uli ndi lead yachitsulo cholemera, yomwe imawononga chilengedwe komanso imaika pachiwopsezo thanzi la anthu, ndipo sumatsatira malamulo azachilengedwe monga EU RoHS.
Zolimbitsa calcium zinc sizili ndi zitsulo zolemera, zimakwaniritsa zofunikira zachilengedwe, ndipo zimalimbana ndi kuipitsidwa ndi sulfure (monga kusasintha kukhala wakuda m'malo okhala ndi mvula ya asidi kumpoto).
3, Magawo Ogwiritsira Ntchito
Chokhazikitsa mchere wa lead: Chifukwa cha mtengo wake wotsika komanso kutchinjiriza bwino magetsi, chinkagwiritsidwa ntchito kwambiri m'mafakitale monga zingwe ndi mapaipi, koma pang'onopang'ono chinachepa.
Chokhazikika cha calcium zinc: choyenera kugwiritsidwa ntchito m'minda yomwe imakhudzidwa ndi chilengedwe monga ma CD a chakudya, zipangizo zachipatala, zitseko ndi mawindo, ndipo palibe chiopsezo cha kuipitsidwa ndi zinthu zina mukasinthana ndi mchere wa lead ndi zokhazikika za organotin.
4, Kusiyana kwina
Kuchuluka ndi Mtengo: Zolimbitsa calcium zinc zimakhala ndi kuchuluka kochepa (pafupifupi 40% kotsika kuposa mchere wa lead), zomwe zimatha kuwonjezera kuchuluka kwa calcium carbonate komwe kumagwiritsidwa ntchito kuchepetsa ndalama.
Kupaka Mafuta: Mchere wa lead uli ndi mafuta abwino, pomwe calcium ndi zinc zimadalira mafuta othandizira kuti azitha kusintha pulasitiki.
Mphamvu yoletsa kutentha kwa zinc: Zolimbitsa zinc za calcium zimafuna kuwonjezera zinthu zina monga polyols ndi phosphites kuti zilepheretse kuwonongeka kwa zinc chloride.
chidule
Ngakhale kuti zolimbitsa mchere wa lead zimagwira ntchito bwino kwambiri, sizimawononga chilengedwe. Zolimbitsa calcium zinc pang'onopang'ono zachepetsa kusiyana kwa magwiridwe antchito kudzera mu kusintha kwaukadaulo (monga zinthu zopangidwa ndi nthaka yosowa) ndipo zakhala njira zina zodziwika bwino zochizira chilengedwe.
