Ntlha ea Bohloko ea 1: Botsitso bo Fosahetseng ba Thermal = Lisebelisoa tse Senyehileng & Rejects
Ho tsieleha ho hoholo? PVC e senyeha habonolo ha e futhumala ka holimo ho 160 ° C-e leng mocheso o fapaneng o sebelisetsoang ho kopanya li-resin tsa PVC le li-plasticizers le ho etsa letlalo la maiketsetso. Ntle le botsitso bo sebetsang, thepa e fetoha mosehla, e hlahisa mapetsong, kapa e ntša mosi o chefo (joaloka hydrochloric acid). Sena se lebisa ho:
• Litefiso tse phahameng tsa lisebelisoa (ho fihla ho 15% lifekthering tse ling).
• Litšenyehelo tsa ho lokisa bocha bakeng sa lihlopha tse nang le bothata
• Ho lieha ho kopana le litaelo tsa bareki
Tharollo: Fetohela ho Li-Composite Stabilizer tse sebetsang hantle haholo
Li-stabilizers tse tloaelehileng tsa karolo e le 'ngoe (mohlala, matsoai a loto) hangata li haelloa ke mocheso nako e telele. Ho e-na le hoo, khethacalcium-zinc (Ca-Zn) e kopanyang li-stabilizerskapa organotin stabilizers-ka bobeli li etselitsoe litlhoko tse ikhethang tsa letlalo la maiketsetso la PVC:
• Metsoako ea Ca-Zn e fana ka botsitso bo babatsehang ba mocheso (ho mamella 180–200°C bakeng sa metsotso e 30+) ’me e lumellana le lintho tse bonolo tse sebelisoang letlalong le tenyetsehang la maiketsetso.
• Organotin stabilizers (mohlala, methyltin) e fana ka ponaletso e phahameng le ho boloka mebala-e loketseng letlalo la maiketsetso la boleng bo holimo (mohlala, feshene ea vegan, upholstery ea maemo a holimo).
• Pro Tip: Kopanya li-stabilizer tse nang le li-co-additives tse kang li-antioxidant kapa li-absorer tsa UV ho atolosa ho hanyetsa mocheso ho ea pele.
Ntlha ea Bohloko ea 2: Ho se Laolehe ha Tikoloho & Taolo
.
Melao ea lefats'e (EU REACH, US CPSC, China's GB Standards) e loantšana le li-stabilizer tse chefo-haholo-holo lead, cadmium, le likhetho tse thehiloeng ho mercury. Baetsi ba bangata ba ntse ba itšetlehile ka matsoai a theko e tlaase, feela ho tobana le:
• Lithibelo ho tsoa kantle ho thepa e felileng
• Litefiso tse boima bakeng sa ho se ikobele melao
• Tšenyo ea botumo ba lebitso (bareki ba batla letlalo la maiketsetso le “tala”).
Tharollo: Adopt Eco-Friendly, Regulatory-Compliant Stabilizers
Lahla litšepe tse boima tse chefo bakeng sa mefuta e meng e se nang lead, e se nang cadmium e fihlelang maemo a lefats'e:
• Li-stabilizers tsa Ca-Zn: Ho lumellana ka botlalo le REACH le RoHS, ho li etsa hore e be tse loketseng bahlahisi ba shebaneng le ho romela thepa kantle ho naha.
• Rare earth stabilizers: Khetho e ncha e kopanyang ho tsitsa ha mocheso le chefo e tlaase-e ntle bakeng sa melapo ea letlalo ea maiketsetso e ngotsoeng eco.
• Hlahloba ketane ea hau ea thepa: Sebetsa le barekisi ba stabilizer ba fanang ka litifikeiti tsa ho latela melao ea motho oa boraro (mohlala, SGS, EUROLAB) ho qoba chefo e patiloeng.
Ntlha ea Bohloko ea 3: Bonolo bo sa Feleng le ho Tšoareha

Boipiletso ba letlalo la maiketsetso bo itšetlehile ka boleng bo ts'oaroang - bo thata haholo, 'me bo hlōleha ho upholstery; e pshatleha haholo, 'me e rusolla lieta. Li-stabilizers li ama sena ka kotloloho: likhetho tsa boleng bo tlase li ka sebetsana le li-plasticizers, tsa fokotsa ho fetoha le maemo kapa tsa etsa hore thepa e thatafale ha nako e ntse e feta.
Tharollo: Tailor Stabilizers ho Qetella Litlhoko tsa ho Sebelisa
Ha se matlalo 'ohle a maiketsetso a tšoanang-kahoo stabilizer ea hau ha ea lokela ho ba joalo. Iketsetse sebopeho sa hau ho latela sehlahisoa:
• Bakeng sa lisebelisoa tse bonolo (mohlala, liatlana, mekotla): Sebelisametsi Ca-Zn stabilizers, e kopanyang ka ho lekana le li-plasticizers ho boloka ho tenyetseha
• Bakeng sa tšebeliso e boima (mohlala, litulo tsa likoloi, mabanta a indasteri): Eketsali-stabilizers tsa barium-zinc (Ba-Zn).ka oli ea soya e epoxidized (ESBO) ho matlafatsa khanyetso ea ho lla
• Lekola lihlopha tse nyane pele: Etsa liteko ka likhakanyo tse fapaneng tsa stabilizer (hangata 1–3% ea boima ba resin ea PVC) ho fumana sebaka se monate lipakeng tsa bonolo le botsitso.
Pain Point 4: Litšenyehelo tse ntseng li phahama tsa Stabilizer Raw Materials
.
Ka 2024-2025, litheko tsa lisebelisoa tsa bohlokoa tsa stabilizer (mohlala, zinc oxide, metsoako ea organic tin) li ile tsa phahama ka lebaka la khaello ea phepelo. Sena se fokotsa menyetla ea phaello bakeng sa bahlahisi ba letlalo ba maiketsetso ba maemo a tlase
Tharollo: Ntlafatsa litekanyetso 'me u hlahlobe li-Blends tse Recycled
• Sebelisa "tekanyetso e fokolang e sebetsang": Ho sebelisa li-stabilizers ho senya chelete ntle le ho ntlafatsa tshebetso. Sebetsa le litsebi tsa lab ho lekola liperesente tse tlase tsa botsitso (hangata 0.8–2%) tse fihlelang maemo a boleng.
• Kopanya li-stabilizers tse recycled: Bakeng sa letlalo la maiketsetso le sa lefelloeng (mohlala, ho paka, lieta tsa theko e tlaase), kopanya 20-30% ea li-stabilizers tsa Ca-Zn le tse sa tsoa tsoaloa-sena se fokotsa litšenyehelo ka 10-15% ntle le ho tela botsitso.
• Notlela likonteraka tsa nako e telele tsa barekisi: Buisana ka litheko tse sa fetoheng le baetsi ba tšeptjoang ba li-stabilizer ho qoba ho fetoha ha litheko.
