Inyongera za PVC ni iki?

Hari ubwoko butandukanye bw'inyongera za PVC (polyvinyl chloride), zishobora kugabanywamo ibice bikurikira hashingiwe ku mirimo yazo, hamwe n'ibintu bihuriweho n'imikoreshereze:

1. Ituma ubushyuhe bukomeza

Imikorere: Kurinda ko HCl irekurwa bitewe no kubora kw'ubushyuhe mu gihe cyo gutunganya cyangwa gukoresha PVC.

Ubwoko busanzwe:

Umunyu wa lead (nk'umunyu wa trisodium lead sulfate): Ihendutse ariko uburozi buri hejuru, buhoro buhoro bugenda bugabanuka.

Iterambere rya zinc muri kalisiyumu: rirengera ibidukikije, rikoreshwa mu gupfunyika ibiryo no mu bikoresho by'ubuvuzi.

Ibinyabutabire by’ibumba (nk’ibinyabutabire bya dibutyltin) bifite ubushobozi bwo kugaragara neza kandi birakwiriye gukoreshwa mu buvuzi.

Rare earth stabilizer: ubundi buryo bushya butangiza ibidukikije.

2. Amamashini akoresha pulasitiki

Imikorere: Kongera ubushobozi bwo koroshya no kugabanya ubushyuhe bw'impinduka mu kirahuri.

Ubwoko busanzwe:

Phthalates (nka DOP, DBP): Yose hamwe, ifite uburozi buke mu gice kimwe (nka DEHP).

Ubundi buryo butangiza ibidukikije: Sitrate esters (ATBC), amavuta ya soya ya epoxidized (ESO), polyester plasticizers.

3. Amavuta yo kwisiga

Imikorere: Kugabanya ubukana bw'imashini no kunoza uburyo zigenda zihinduka.

Icyiciro:

Amavuta yo mu nda (nk'aside stearike): agabanya uburyaryate hagati ya molekile za PVC.

Amavuta yo hanze (nk'amavuta ya parafini): agabanya ubukana hagati ya PVC n'ibikoresho.

4. Guhindura ingaruka

Imikorere: Kunoza ubudahangarwa bw'ingaruka.

Ubwoko busanzwe:

CPE (Polyethylene ifite Chloride): Ihendutse cyane.

MBS (methyl methacrylate butadiene styrene copolymer): ikwiriye ibikoresho bibonerana.

ACR (ester akriliki): Ikoranabuhanga ryiza cyane.

5. Ibikoresho bifasha mu gutunganya

Imikorere: Kunoza imbaraga zo gushonga no kugenda neza kw'amazi.

Ubwoko busanzwe: ACR (nk'uruhererekane rwa Paraloid), EVA (ethylene vinyl acetate copolymer).

6. Ibintu bigabanya umuriro

Imikorere: Ibuza gutwika, ikoreshwa mu bikoresho by'ubwubatsi, insinga n'insinga.

Ubwoko:

Ibikoresho bidafite umwimerere: aluminium hydroxide, magnesium hydroxide (irinda ibidukikije ariko ifite inyongeramusaruro nyinshi).

Ibinyabutabire by’umwimerere: Ibinyabutabire bya bromine (nk'iya decabromodiphenyl ether, ifite agace gato k’ibinyabutabire), ibinyabutabire bya fosifore (nk'iya fosifore esters).

7. Ituma urumuri rudahindagurika

Imikorere: Irwanya gusaza kw'imirasire y'izuba, ikoreshwa mu bikoresho byo hanze.

Ubwoko busanzwe:

Udukoresho dufata imirasire ya UV (nk'imiti yitwa benzotriazoles).

Umuti ugabanya ubukana bw'urumuri rw'amine (HALS).

8. Ibikoresho byuzuza

Imikorere: Kugabanya ikiguzi no kugenzura imikorere.

Ingero: Karuboneti ya Kalisiyumu (kalisiyumu yoroheje / kalisiyumu nyinshi), ifu ya talc, na wollastonite.

9. Amarangi

Ubwoko:

Amabara y'umwimerere: afite amabara meza cyane.

Amabara atari ay’umwimerere: arwanya ikirere neza.

Bontecn Group China yibanda ku gukora inyongeramusaruro za PVC, Kuri ubu, iyi sosiyete ifite abakozi 5 bakuru bo mu bushakashatsi no mu iterambere, abakozi barenga 20 bo mu bushakashatsi no mu iterambere, n'amatsinda arenga 20 akorana. Ubu iyi sosiyete n'ibigo bizwi cyane byo mu mahanga bifatanyije mu gukora ibicuruzwa bishya, ibi bicuruzwa bishobora gukemura ibibazo by'ibikoresho bya pulasitiki bisanzwe n'ibibazo bihendutse, kandi byageze ku musaruro ugaragara. Dukoresheje ikoranabuhanga rigezweho mu gutunganya ibintu n'uburyo bwiza bwo kubitahura, dukomeje gushakisha, kwibanda ku bushakashatsi no guteza imbere ibintu, no gukorana n'ibigo by'ubushakashatsi bya siyansi umwaka wose kugira ngo dukomeze guteza imbere ibicuruzwa bishya n'imikorere mishya.
