Li-Stabilizer tsa Metsi tsa Barium Zinc PVCke di-additi tse ikgethang tse sebediswang tshebetsong ya polyvinyl chloride (PVC) ho ntlafatsa botsitso ba mocheso le lesedi, ho thibela ho senyeha nakong ya tlhahiso le ho atolosa nako ya bophelo ba thepa. Mona ke tlhaloso e qaqileng ya sebopeho sa tsona, ditshebediso, dintlha tsa taolo le mekgwa ya mmaraka:
Sebopeho le Mokhoa
Hangata di-stabilizer tsena di na le matswai a barium (mohlala, alkylphenol barium kapa 2-ethylhexanoate barium) le matswai a zinc (mohlala, 2-ethylhexanoate zinc), tse kopantsweng le dikarolo tse sebedisanang jwalo ka phosphites (mohlala, tris(nonylphenyl) phosphite) bakeng sa chelation le di-solvents (mohlala, oli ya diminerale) bakeng sa ho hasana. Barium e fana ka tshireletso ya mocheso wa nako e kgutshwane, ha zinc e fana ka botsitso ba nako e telele. Sebopeho sa mokelikeli se netefatsa ho kopanngwa ka ho tshwana ditokisetsong tsa PVC. Ditokisetso tsa moraorao di boetse di kenyelletsa di-ester tsa polyether silicone phosphate ho ntlafatsa ho tlotsa le ho pepeseha, ho fokotsa ho monngwa ha metsi nakong ya ho phodisa.
Melemo ea Bohlokoa
Ha e na chefo: Ha e na litšepe tse boima tse kang cadmium, li latela maemo a ho kopana le lijo le a bongaka (mohlala, likereiti tse amohetsoeng ke FDA mefuteng e meng).
Bokgoni ba ho Sebetsa: Boemo ba metsi bo netefatsa ho hasana ha bonolo ka har'a metsoako e bonolo ea PVC (mohlala, lifilimi, lithapo), ho fokotsa nako ea ts'ebetso le tšebeliso ea matla.
Ho Sebetsa ka Botlalo Litšenyehelo: Tlholisanong le li-stabilizer tsa tin ea organic ha ka nako e ts'oanang ho qoba matšoenyeho a chefo.
Liphello tsa ho sebelisana 'moho: Ha li kopantsoe le li-stabilizer tsa calcium-zinc, li sebetsana le mathata a "ho lelefatsa" ho tsoa ha PVC e tiileng ka ho leka-lekanya ho tlotsa le botsitso ba mocheso.
Likopo
Lihlahisoa tse bonolo tsa PVC: E sebelisoa haholo lifiliming tse tenyetsehang, likhoele, letlalo la maiketsetso le lisebelisoa tsa bongaka ka lebaka la ho se be chefo le ho boloka ho hlaka ha tsona.
PVC e tiileng: E kopantsoe leli-stabilizer tsa calcium-zinc, li ntlafatsa bokhoni ba ho sebetsa lifiliming le liprofaeleng, li fokotsa "ho thella ha lintho tse bonahalang nakong ea ho ntša).
Likopo tse Ikhethang: Metswako e pepeneneng haholo bakeng sa ho paka le dihlahiswa tse hanelang UV ha di kopantswe le di-antioxidants tse kang 2,6-di-tert-butyl-p-cresol.
Mehopolo ea Taolo le Tikoloho
Ho latela Molao oa REACH: Metswako ya Barium e laolwa tlasa REACH, ka dithibelo hodima barium e qhibilihang (mohlala, ≤1000 ppm dihlahisweng tsa bareki). Bongata ba di-stabilizer tsa barium tse metsi di fihlella meedi ena ka lebaka la ho qhibiliha ho tlase.
Mekhoa e meng: Li-stabilizer tsa calcium-zinc li ntse li hola ka lebaka la melao e thata ea tikoloho, haholo-holo Europe. Leha ho le joalo, li-stabilizer tsa barium zinc li ntse li khethoa haholo lits'ebetsong tse chesang haholo (mohlala, likarolo tsa likoloi) moo calcium-zinc feela e ka 'nang ea se lekane.
Lintlha tsa Tshebetso le tsa Tekheniki
Ho Tsitsisa ha Thermal: Liteko tsa mocheso o sa fetoheng li bontša botsitso bo bolelele (mohlala, metsotso e 61.2 ho 180°C bakeng sa metsoako e nang le li-co-stabilizer tsa hydrotalcite). Ts'ebetso e matla (mohlala, extrusion ea li-screw tse peli) e rua molemo ho tsoa thepa ea tsona ea ho tlotsa, e fokotsang ho senyeha ha shear.
Ponaletso: Metswako e tsoetseng pele e nang le li-ester tsa silicone tsa polyether e fihlella ho hlaka ho hoholo ha optical (phetiso ea ≥90%), e leng se etsang hore e lokele lifilimi tsa ho paka.
Khanyetso ea ho Falla: Li-stabilizer tse entsoeng hantle li bontša ho falla ho tlase, e leng tsa bohlokoa bakeng sa lits'ebetso tse kang liphutheloana tsa lijo moo ho falla ha lintho tse ling ho leng taba e tšoenyang.
Malebela a ho Sebetsa
Ho lumellanaQoba ho sebelisa mafura a stearic acid ka bongata, kaha a ka 'na a arabela le letsoai la zinki, e leng se potlakisang ho senyeha ha PVC.li-co-stabilizerjoalo ka oli ea soya e nang le epoxidized ho ntlafatsa ho lumellana.
Tekanyo: Tšebeliso e tloaelehileng e tloha ho 1.5-3 phr (likarolo ka lekholo la resin) ho PVC e bonolo le 0.5-2 phr ho metsoako e tiileng ha e kopantsoe le li-stabilizer tsa calcium-zinc.
Mekhoa ea 'Maraka
Bakhanni ba Kholo: Tlhoko ea li-stabilizer tse se nang chefo Asia-Pacific le Amerika Leboea e sutumelletsa boqapi mefuteng ea barium zinc. Mohlala, indasteri ea PVC ea Chaena e ntse e sebelisa li-stabilizer tsa barium zinc tse metsi ka ho eketsehileng bakeng sa tlhahiso ea terata/thapo.
Liphephetso: Keketseho ea li-stabilizer tsa calcium-zinc (e hakanyetsoang hore ke CAGR ea 5–7% thepa ea lieta le likarolo tsa ho paka) e hlahisa tlholisano, empa barium zinc e ntse e boloka sebaka sa eona lits'ebetsong tse sebetsang hantle.
Li-stabilizer tsa Liquid Barium Zinc PVC li fana ka tekano ea katleho ea litšenyehelo, botsitso ba mocheso, le ho latela melao ea tsamaiso, e leng se etsang hore li be bohlokoa haholo lihlahisoa tsa PVC tse bonolo le tse thata hanyane. Leha likhatello tsa tikoloho li khanna phetoho ho ea ho mekhoa e meng ea calcium-zinc, thepa ea tsona e ikhethang e netefatsa hore e tsoela pele ho ba bohlokoa limmarakeng tse ikhethileng. Baetsi ba lihlahisoa ba tlameha ho leka-lekanya ka hloko litlhoko tsa ts'ebetso le litataiso tsa taolo ho eketsa melemo ea bona.
