Ingaruka zubushyuhe bwubushyuhe kubicuruzwa bya PVC: Kurwanya Ubushyuhe, Gutunganya, Gukorera mu mucyo

Uru rupapuro rugaragaza uburyo stabilisateur zigira ingaruka kubicuruzwa bya PVC, byibandakurwanya ubushyuhe, gutunganywa, no gukorera mu mucyo. Mugusesengura ubuvanganzo namakuru yubushakashatsi, turasuzuma imikoranire hagati ya stabilisateur na PVC resin, nuburyo bigira ituze ryumuriro, ubworoherane bwo gukora, nibintu byiza.

1. Intangiriro

PVC ni thermoplastique ikoreshwa cyane, ariko ihungabana ryumuriro rigabanya gutunganya.Ubushyuhe bwo gushyushyakugabanya kwangirika kurwego rwo hejuru kandi nanone bigira ingaruka kumikorere no gukorera mu mucyo - ingenzi kubisabwa nko gupakira hamwe na firime yububiko.

2. Kurwanya Ubushyuhe bwa Stabilisateur muri PVC

2.1 Uburyo bwo gutuza

Imiterere itandukanye (kuyobora - ishingiye,calcium - zinc, organotine) koresha uburyo butandukanye:

Kuyobora - bishingiye: Kora hamwe na labile Cl atom muminyururu ya PVC kugirango ukore ibintu bihamye, wirinde kwangirika.
Kalisiyumu - zinc: Huza aside - guhuza hamwe na radical - guswera.
Organotine (methyl / butyl tin): Huza iminyururu ya polymer kugirango ubuze dehydrochlorine, guhagarika neza kwangirika.

2.2 Gusuzuma Ubushyuhe bwumuriro

Isesengura rya Thermogravimetric (TGA) ryerekana organotine - PVC itajegajega ifite umuvuduko mwinshi wo kugabanuka kurenza calcium gakondo - sisitemu ya zinc. Mugihe icyerekezo - gishingiye kuri stabilisateur gitanga igihe kirekire - gutezimbere mubikorwa bimwe na bimwe, ibidukikije / ubuzima bibuza gukoresha.

3. Ingaruka Zitunganijwe

3.1 Gushonga gutemba & Viscosity

Stabilisateur ihindura imyitwarire ya PVC:

Kalisiyumu - zinc: Irashobora kongera gushonga kwijimye, ikabuza gukuramo / guterwa inshinge.
Organotin: Kugabanya ubukonje bworoshye, hasi - gutunganya temp - byiza kumurongo wo hejuru - umuvuduko.
Kuyobora - bishingiye.

3.2 Amavuta & Kurekura

Stabilisateurs zimwe zikora nk'amavuta:

Kalisiyumu - ibice bya zinc akenshi birimo amavuta yimbere kugirango atezimbere irekurwa muburyo bwo gutera inshinge.
Stabilisateur ya Organotine itera PVC - guhuza inyongera, gufasha mu buryo butaziguye.

4. Ingaruka ku mucyo

4.1 Imikoranire nuburyo bwa PVC

Gukorera mu mucyo biterwa no gukwirakwiza stabilisateur muri PVC:

Nibyiza - yatatanye, ntoya - agace ka calcium - stabilisateur ya zinc igabanya urumuri rutatanye, rukarinda neza.
Imiterere ya organotinekwinjiza muminyururu ya PVC, kugabanya kugoreka optique.
Kurongora - bishingiye kuri stabilisateur (binini, bigabanijwe ku buryo butaringaniye) bitera urumuri rukabije gutatanya, bigabanya umucyo.

4.2 Ubwoko bwa Stabilisateur & Gukorera mu mucyo

Ubushakashatsi bugereranya bwerekana:

Organotine - firime ya PVC itajegajega igera> 90% yohereza urumuri.
Kalisiyumu - stabilisateur ya zinc itanga ~ 85-88%.
Kurongora - stabilisateur ikora nabi.

Inenge nka "amaso y amafi" (ihujwe nubwiza bwa stabilisateur / gutatanya) nayo igabanya ubwumvikane - stabilisateur yo mu rwego rwo hejuru igabanya ibyo bibazo.

5. Umwanzuro

Ubushyuhe bwo gushyushya ni ingenzi mu gutunganya PVC, gushiraho ubushyuhe, gutunganya, no gukorera mu mucyo:

Kuyobora - bishingiye: Tanga ituze ariko uhure nibidukikije.
Kalisiyumu - zinc: Eco - inshuti ariko ikeneye kunonosorwa mubikorwa / gukorera mu mucyo.
Organotin: Excel mubice byose ariko ihura nigiciro / inzitizi zubuyobozi mukarere kamwe.

Ubushakashatsi bw'ejo hazaza bugomba guteza imbere stabilisateur iringaniza irambye, gutunganya neza, hamwe nubwiza bwa optique kugirango ihuze ibyifuzo byinganda.
