Zithini izongezo zePVC?

Kukho iintlobo ngeentlobo zezongezo zePVC (i-polyvinyl chloride), ezinokwahlulwa zibe ziindidi ezilandelayo ngokusekwe kwimisebenzi yazo, kunye nezithako ezithile eziqhelekileyo kunye nokusetyenziswa okuqhotyoshelweyo:

1. Isiqinisi sobushushu

Umsebenzi: Ukuthintela ukukhutshwa kwe-HCl ngenxa yokubola kobushushu ngexesha lokucubungula okanye ukusebenzisa i-PVC.

Iintlobo eziqhelekileyo:

Iityuwa ze-lead (ezifana ne-trisodium lead sulfate): Ixabiso liphantsi kodwa inetyhefu ephezulu, iphela kancinci kancinci.

Isiqinisi se-calcium zinc: sinobuhlobo nokusingqongileyo, sisetyenziselwa ukupakisha ukutya kunye nezixhobo zonyango.

Iikhompawundi ze-organic tin (ezifana ne-dibutyltin) zibonakala kakuhle kwaye zifanelekile kwiimveliso zonyango.

Isiqinisi somhlaba esingaqhelekanga: enye indlela entsha enobuhlobo nokusingqongileyo.

2. Izinto zokucoca iiplastiki

Umsebenzi: Yandisa ukuguquguquka kwaye wehlise ubushushu bokutshintsha kweglasi.

Iintlobo eziqhelekileyo:

Ii-Phthalates (ezifana ne-DOP, i-DBP): Zizonke, zinobuthi obuncinci (ezifana ne-DEHP).

Ezinye iindlela ezinobuhlobo nokusingqongileyo: Ii-esters ze-Citrate (ATBC), ioyile yesoya e-epoxidized (ESO), iiplastiki ze-polyester.

3. Izinto zokuthambisa

Umsebenzi: Nciphisa ukungqubana komatshini kwaye uphucule ukugeleza kwamanzi.

Udidi:

Izinto zokuthambisa zangaphakathi (ezifana ne-stearic acid): zinciphisa ukungqubana kwe-PVC phakathi kweemolekyuli.

Izinto zokuthambisa zangaphandle (ezifana neparafini): zinciphisa ukungqubana phakathi kwePVC nezixhobo.

4. Isiguquli sempembelelo

Umsebenzi: Ukuphucula ukuxhathisa impembelelo.

Iintlobo eziqhelekileyo:

I-CPE (iPolyethylene eneChlorin): Ixabiso layo liphezulu kwaye iyasebenza.

I-MBS (i-methyl methacrylate butadiene styrene copolymer): ifanelekile kwiimveliso ezicacileyo.

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

5. Izixhobo zokucubungula

Umsebenzi: Ukuphucula amandla okunyibilika kunye nokuhamba kakuhle kwamanzi.

Iintlobo eziqhelekileyo: I-ACR (ezifana ne-Paraloid series), i-EVA (i-ethylene vinyl acetate copolymer).

6. Izinto ezithintela ilangatye

Umsebenzi: Ukuthintela ukutsha, okusetyenziswa kwizixhobo zokwakha, kwiingcingo nakwiintambo.

Uhlobo:

Izinto ezingaphiliyo: i-aluminium hydroxide, i-magnesium hydroxide (enobuhlobo nokusingqongileyo kodwa inezithako ezininzi).

Iikhompawundi ze-organic: Iikhompawundi ze-bromine (ezifana ne-decabromodiphenyl ether, ezithintelwe kancinci), iikhompawundi ze-phosphorus (ezifana nee-phosphate esters).

7. Isiqinisi sokukhanya

Umsebenzi: I-Anti UV aging, isetyenziselwa iimveliso zangaphandle.

Iintlobo eziqhelekileyo:

Izifunxi ze-UV (ezifana ne-benzotriazoles).

Isithinteli sokukhanya kwe-amine esithintelweyo (HALS).

8. Izizalisi

Umsebenzi: Nciphisa iindleko kwaye ulawule ukusebenza.

Imizekelo: I-calcium carbonate (i-calcium ekhaphukhaphu/i-calcium enzima), umgubo we-talc, kunye ne-wollastonite.

9. Izinto zokufaka imibala

Uhlobo:

Iipigment zendalo: ezinemibala eqaqambileyo.

Ii-pigment ezingaphiliyo: ukumelana kakuhle nemozulu.

I-Bontecn Group China igxile ekuveliseni izongezo ze-PVC, Okwangoku, inkampani inabasebenzi aba-5 abaphezulu be-R & D, abasebenzi abaphakathi be-R & D abangaphezu kwama-20, kunye namaqela asebenzisanayo angaphezu kwama-20. Ngoku inkampani kunye namashishini aziwayo angaphandle baphuhlisa imveliso entsha kunye, imveliso inokusombulula iingxaki zesiqhelo zezithako zeplastiki kunye neengxaki ezibiza kakhulu, kwaye ifumene iziphumo ezibalulekileyo. Ngobuchwepheshe benkqubo obuphambili kunye neendlela ezigqibeleleyo zokufumanisa, siyaqhubeka nokuphonononga, sigxile kuphando nophuhliso, kwaye sisebenzisane namaziko ophando lwesayensi unyaka wonke ukuphuhlisa iimveliso ezintsha kunye neenkqubo ezintsha rhoqo.
