Ziyini izithasiselo ze-PVC?

Kunezinhlobo ezahlukene zezithasiselo ze-PVC (i-polyvinyl chloride), ezingahlukaniswa ngezigaba ezilandelayo ngokusekelwe emisebenzini yazo, kanye nezithako ezithile ezivamile kanye nokusetshenziswa okunamathiselwe:

1. Isiqinisi sokushisa

Umsebenzi: Ukuvimbela ukukhishwa kwe-HCl ngenxa yokubola kokushisa ngesikhathi sokucubungula noma ukusebenzisa i-PVC.

Izinhlobo ezivamile:

Usawoti we-lead (njenge-trisodium lead sulfate): Izindleko eziphansi kodwa ubuthi obuphezulu, buphela kancane kancane.

Isiqinisi se-calcium zinc: esinobungani nemvelo, esisetshenziselwa ukupakisha ukudla kanye namadivayisi ezokwelapha.

Ama-organic tin compounds (njenge-dibutyltin) anokukhanya okuhle futhi afanelekela imikhiqizo yezokwelapha.

Isiqinisi somhlaba esingavamile: enye indlela entsha enobungani nemvelo.

2. Izinto zokwenziwa ngepulasitiki

Umsebenzi: Khulisa ukuguquguquka kanye nokwehlisa izinga lokushisa lokushintsha kwengilazi.

Izinhlobo ezivamile:

Ama-phthalates (njenge-DOP, i-DBP): Ahlanganisa wonke, anqunyelwe kancane ebuthi (njenge-DEHP).

Ezinye izindlela ezinobungani nemvelo: Ama-ester e-Citrate (ATBC), uwoyela wesoya oxutshwe ne-epoxidized (ESO), ama-plasticizer e-polyester.

3. Izinto zokugcoba

Umsebenzi: Nciphisa ukungqubuzana komshini futhi uthuthukise ukugeleza kwamanzi.

Isigaba:

Izinto zokugcoba zangaphakathi (njenge-stearic acid): zinciphisa ukungqubuzana kwamangqamuzana e-PVC.

Izinto zokugcoba zangaphandle (njenge-parafini): zinciphisa ukungqubuzana phakathi kwe-PVC nemishini.

4. Isiguquli somthelela

Umsebenzi: Thuthukisa ukumelana nokushayisana.

Izinhlobo ezivamile:

I-CPE (i-Polyethylene ene-Chloride): Isebenza kahle kakhulu ngezindleko.

I-MBS (i-methyl methacrylate butadiene styrene copolymer): ifanele imikhiqizo esobala.

I-ACR (i-acrylic ester): Ukusebenza okuhle kakhulu okuphelele.

5. Izinsiza zokucubungula

Umsebenzi: Thuthukisa amandla okuncibilika kanye nokugeleza kwamanzi.

Izinhlobo ezivamile: I-ACR (njenge-Paraloid series), i-EVA (i-ethylene vinyl acetate copolymer).

6. Izinto ezivimbela ilangabi

Umsebenzi: Ukuvimbela ukusha, okusetshenziswa ezintweni zokwakha, izintambo kanye nezintambo.

Uhlobo:

Izinto ezingaphili: i-aluminium hydroxide, i-magnesium hydroxide (enobungani nemvelo kodwa enezithasiselo eziningi).

Amakhemikhali e-organic: Amakhemikhali e-bromine (njenge-decabromodiphenyl ether, anqunyelwe kancane), amakhemikhali e-phosphorus (njenge-phosphate esters).

7. Isiqinisi sokukhanya

Umsebenzi: I-Anti UV aging, esetshenziselwa imikhiqizo yangaphandle.

Izinhlobo ezivamile:

Izifutho ze-UV (njenge-benzotriazoles).

Isiqinisi sokukhanya kwe-amine esithintekile (HALS).

8. Ama-Filler

Umsebenzi: Nciphisa izindleko futhi ulawule ukusebenza.

Izibonelo: I-calcium carbonate (i-calcium elula/i-calcium esindayo), i-talc powder, kanye ne-wollastonite.

9. Izinto zokufaka imibala

Uhlobo:

Imibala yezinto eziphilayo: enemibala egqamile.

Izinhlayiya ezingaphili: ukumelana okuhle nesimo sezulu.

I-Bontecn Group China igxile ekukhiqizeni izithasiselo ze-PVC, Njengamanje, inkampani inabasebenzi abaphezulu aba-5 be-R & D, abasebenzi abaphakathi abangaphezulu kuka-20 be-R & D, kanye namaqembu abambisene angaphezu kuka-20. Manje inkampani kanye namabhizinisi aziwayo angaphandle bathuthukisa umkhiqizo omusha ngokubambisana, umkhiqizo ungaxazulula izinkinga zezithako zepulasitiki zendabuko nezinkinga ezibiza kakhulu, futhi uthole imiphumela ebalulekile. Ngobuchwepheshe benqubo obuthuthukisiwe kanye nezindlela zokuthola eziphelele, siyaqhubeka nokuhlola, sigxile ocwaningweni nasekuthuthukisweni, futhi sibambisana nezikhungo zocwaningo lwesayensi unyaka wonke ukuze sithuthukise njalo imikhiqizo emisha kanye nezinqubo ezintsha.
