Ukuqonda ama-PVC ezigcina: Iqhaza le-calcium-zinc kanye nezinye izindlela zokuhola

I-Polyvinyl Chloride (PVC), enye yama-thermoplastics ahlukahlukene kakhulu, ingazinzile ngokuzinzile lapho kuvezwa ukushisa, imisebe ye-UV, noma ukucindezelwa kwemishini ngesikhathi sokulungiswa nesicelo. Ukulwa nokonakaliswa, abaqinisi ababucayi izithasiselo. Phakathi kwalokhu, abaqinisi be-calcium-zinc) nabaqinisi abasezingeni eliphansi bamelela izindlela ezimbili ezihlukile, ngamunye anezinzuzo nezinselelo ezihlukile.

1. Ukuqiniswa okusekelwe ekuholeni: ifa elahlayo

Abaqiniswa abasezingeni eliphakeme, njenge-dibasic ehola i-carbonate noma i-lead stearate, bathandwa ngokomlando ngenxa yokusebenza kwabo izindleko kanye nokuqina kokushisa okuphakeme. Bakhipha ngempumelelo i-hydrochloric acid (HCL) ekhishwe ngesikhathi sokuwohloka kwe-PVC, ukuvimbela ukuwohloka kwe-autocatalytic. Kodwa-ke, ubuthi babo nobungozi bezemvelo baholele kwimithetho eqinile. Isibonelo, umthetho we-European Union (EU) uvimba okuqukethwe okuholela ekutholeni okuqukethwe ku-PVC kuya ku- <0.1%, ukusheshisa ukushintshwa kwezinye izindlela eziphephile.

2. I-calcium-zinc contailivilizer: enye indlela ye-eco-friendly

Ama-calcium-zinc angganiliving, ahlanganiswe ne-calcium kanye ne-zinc usawoti ehlanganiswe nama-organic acid, bhekisa ukukhathazeka kwemvelo kanye nezempilo. Azinobuthi, zihambisana nemigomo yomhlaba wonke (isib. Ukufinyelela kanye nama-rohs), kanye nokuhambisana nezinhloso zokusimama. Izinzuzo ezibalulekile zifaka:

Ukuqina -Heat: Vikela ukonakaliswa okushisayo ngesikhathi sokucubungula okushisa kakhulu (isib., Ukukhishwa noma ukugoqa).

-Ukumelana: Vikela imikhiqizo ye-PVC efana namaphrofayili ewindows nezintambo zangaphandle ezivela ekubumbeni nasekusebenzeni.

-Verasticility: Kutholakala kumabanga akhethekile, njengokutholakala kokutholwa kokudla, okuphansi, kanye nokwakheka okusobala, ukunakekela izimboni ezahlukahlukene njengokukhiwa, izimoto, nokupakipha.

3. Ukusebenza kanye Nezitayela Zemakethe

Ngenkathi ukuqina okusekelwe ekuholeni kukhombisa ukuqina okungcono kakhulu okushisayo okushisayo, ama-calcium-zinc avale igebe lokusebenza ngokusebenzisa ukwakheka okuthuthukile. Isibonelo, ama-Synergies anama-co-anatilivings anjenge-mineral acid scavenger athuthukisa ukusebenza kahle. Imakethe yomhlaba wonke yokugcina ama-PVC ama-PVC, abiza ama- $ 3.48 billion ngo-2023, kulindeleke ukuthi afinyelele ku- $ 4.77 billion ngo-2030, aqhutshwa yizingcindezi zokulawula kanye nezinto ezintsha ezinjengezinto ezintsha ezithathwe ngamafutha.

4. Izicelo kanye nokubuka okuzayo

I-calcium-zinc Stungonicers iphatha izinhlelo zokusebenza ezidinga ukuphepha nokuqina:

I -Construction: Amapayipi, ozimele bewindi, kanye nokuhambisana.

-Automotive: Izimpawu zangaphakathi nezimpawu.

Ukupakishwa -Food: Amafilimu ahambisanayo neziqukathi. Ukuqhubeka kwe-R & D kugxile ekwandeni ukusebenza kwezindleko kanye nokwandisa amacala okusebenzisa, njenge-PVC eguqukayo ye-wiring namadivayisi wezokwelapha.

Ukugcina

Ukushintshwa kusuka ku-Lead-kususelwa ku-calcium-zinc Stungores kugcizelela ukuzibophezela komkhakha we-PVC ekusimuseni. Ngenkathi izinselelo ezinjengezindleko eziphakeme kakhulu ziqhubeka ziqhubeka, ukuhambisana nesikhathi eside okulawulwa, ukuphepha kwemvelo kanye nokusebenza okuhlukahlukene - ukuqinisa ama-calcium-zinc systems njengekusasa lokuzinza kwe-PVC. Njengoba ubuchwepheshe buvela, laba abaqinisi bazodlala indima ebaluleke kakhulu ekuvuseni imikhiqizo eluhlaza e-PVC emhlabeni jikelele.
