Qala ka Boikamahanyo ba Taolo: Maemo a Tšireletseho a sa Buisanoeng
Pele o lekola ts'ebetso, beha pele li-stabilizer tse fihlelang melaoana e ikhethileng ea tikoloho le ts'ebeliso - ho se ikobele sehlahiswa se hopolang likotsi le lithibelo tsa phihlello ea mebaraka.
• Lithibelo tsa Lefatše ka Litšepe tse Boima:Li-stabilizer tse thehiloeng ho lead, cadmium le mercury li thibetsoe haholo bakeng sa thepa ea bareki joalo ka lifofu tsa Venetian. EU's REACH Regulation (Annex XVII) e thibela pele ho lihlahisoa tsa PVC tse ka holimo ho 0.1%, ha US CPSC e thibela pelehi le cadmium libakeng tsa bana (mohlala, li- blinds tsa bana). Esita le limmarakeng tse ntseng li hōla, GB 28481 ea Chaena le litekanyetso tsa India tsa BIS li laela hore ho felisoe lihlahisoa tsa tšepe e boima.
• Litlhoko tsa Boleng ba Moea o ka Hare (IAQ):Bakeng sa lifofu tsa bolulo kapa tsa khoebo, qoba li-stabilizer tse nang le phthalates kapa volatile organic compounds (VOCs). Lenaneo la US EPA's Indoor AirPLUS le EU's EcoLabel li rata lisebelisoa tse tlase tsa VOC, tse etsangcalcium-zinc (Ca-Zn)kapa mefuta e meng ea thini ea manyolo e ratoang ho feta metsoako ea setso ea Barium-Cadmium-Zinc (Ba-Cd-Zn).
• Khokahano ea Lijo kapa Boteng ba Bongaka:Haeba lifofu li sebelisoa ka kichineng kapa litsing tsa tlhokomelo ea bophelo, khetha li-stabilizer tse lumellanang le FDA 21 CFR §175.300 (US) kapa EU 10/2011 (lisebelisoa tsa polasetiki tse amanang le lijo), joalo ka methyl tin mercaptides kapa li-high-purity Ca-Zn complexes.
Lekola Tšebelisano ea Ts'ebetso
Ts'ebetso ea stabilizer e ipapisitse le hore na e hokahane hantle hakae le komporo ea hau ea PVC le ts'ebetso ea tlhahiso
• Tšebelisano ea Mola oa Extrusion:Bakeng sa phepelo e sa khaotseng ea li-slats tse foufetseng, qoba li-stabilizers tse bakang ho bokellana ha lefu (mohlala, Ca-Zn ea boleng bo tlase e nang le li-acid tse ngata tse mafura). Khetha li-stabilizers tse kopantsoeng pele (ho e-na le metsoako ea phofo) ho etsa bonnete ba ho hasana ka mokhoa o ts'oanang, ho fokotsa phapang ea botenya ba slat.
• Synergy ea Lubrication:Hangata li-stabilizers li sebetsa ka mafura (mohlala, boka ba polyethylene) ho ntlafatsa phallo.Li-stabilizers tsa Ca-Znhloka mafura a ka hare a lumellanang ho thibela "plate-out" (masala a holim'a letlapa), athe li-stabilizer tsa tin li kopane hantle le litlolo tse tsoang ka ntle bakeng sa ho lokolloa ha lefu hamonate.
• Batch vs. Tlhahiso e Tsoelang Pele:Bakeng sa li-blinds tse nyane, tse mebala e ikhethileng, li-stabilizer tsa mokelikeli (mohlala, Ca-Zn) li fana ka tokiso e bonolo ea litekanyetso. Bakeng sa tlhahiso ea molumo o phahameng, li-stabilizer masterbatches tse tiileng li netefatsa ho tsitsisa.
Litšenyehelo tsa Tekanyo, Moshoelella, le Botsitso ba Chain ea Phepelo
Le hoja ts'ebetso e le ea bohlokoa, lintlha tse sebetsang tse kang litšenyehelo le phello ea tikoloho li ke ke tsa hlokomolohuoa
• Litšenyehelo-ka katleho:Li-stabilizers tsa Ca-Zn li fana ka tekanyo e ntle ka ho fetisisa ea ts'ebetso le litšenyehelo bakeng sa lifofu tse ngata tsa ka tlung (20-30% e theko e tlaase ho feta thini ea tlhaho). Ba-Zn e na le chelete e ngata bakeng sa ts'ebeliso ea kantle empa e e qobe bakeng sa lits'ebetso tsa kahare ka lebaka la likotsi tsa chefo.
• Moshoelella & Recyclability:Khetha li-stabilizer tse tšehetsang litsamaiso tse chitja tsa PVC. Ca-Zn e tsamaellana ka botlalo le ts'ebetso ea mochini (ho fapana le lead kapa cadmium, e silafatsang PVC e sebelisitsoeng hape). Bio-based Ca-Zn (e nkiloeng ho li-feedstocks tse ka nchafatsoang) e hokahana le Leano la Ts'ebetso la Circular Economy la EU le tlhoko ea bareki ea lihlahisoa tse bolokang tikoloho.
• Tšepahalang ea Chain Chain:Litheko tsa zinki le thini lia fetoha- khetha li-stabilizer tse nang le mehloli e mengata (mohlala, Ca-Zn blends) ho e-na le li-niche formulations (mohlala, butyl tin) ho qoba tieho ea tlhahiso.
Teko le netefatso: Litlhahlobo tsa ho Qetela Pele ho Tlhahiso e Felletseng
Pele u itlama ho stabilizer, etsa liteko tsena ho netefatsa ts'ebetso:
.
• Teko ea Botsitso ba Mocheso:Ntšetsa li-slats tsa sampuli 'me u li behe ho 200°C ka metsotso e 30-hlahloba hore na ha e na 'mala kapa ho senyeha.
• Teko ea Boemo ba Leholimo:Sebelisa lebone la xenon arc ho etsisa lihora tse 1,000 tsa mahlaseli a UV-lekanya ho boloka mebala (ka spectrophotometer) le botšepehi ba sebopeho.
• IAQ Test:Sekaseka likhase tsa VOC ho latela ASTM D5116 (US) kapa ISO 16000 (EU) ho netefatsa hore ho latela litekanyetso tsa ka tlung.

• Netefatsa Ts'ebetso:Lekola botsitso ba mocheso, boemo ba leholimo, le mechanics
• Ntlafatsa Litšenyehelo/Moshoelella:Ca-Zn ke ea kamehla bakeng sa lits'ebetso tse ngata; organic tin feela bakeng sa lifofu tsa boleng bo holimo, tse nang le molumo o tlase
Ka ho latela moralo ona, o tla khetha setsi sa botsitso se ntlafatsang ho tšoarella ho sa boneng, se kopanang le melaoana ea 'maraka, le ho ikamahanya le lipheo tsa ts'ebetso-tse bohlokoa bakeng sa tlholisano 'marakeng oa lefatše oa PVC oa Venetian.
