Uburyo bwo gushushanya imashini za V-0 zikoresha thermoplastic za PVC zitagira umuriro

Kugira ngo ugere ku gipimo cya V-0 cyo kudashira kw'umuriro (hakurikijwe ibipimo bya UL-94) muri pulasitiki ya PVC ikoreshwa mu bushyuhe, aluminium hypophosphite na aside boric ni ibintu bibiri bikunze gukoreshwa mu kudashira kw'umuriro. Ingano yabyo igomba kunozwa hashingiwe ku buryo bwihariye bwo kuyitunganya, imiterere yo kuyitunganya, n'ibisabwa mu mikorere. Hasi hari inama zimwe na zimwe n'uburyo bwo kuyikoresha:

1. Inyongera y'urwego rwa Aluminium Hypophosphite

Hypophosphite ya aluminiyumu ni umuti urinda umuriro ushingiye kuri fosifore ukwiriye ibikoresho bya PVC. Ubuza umuriro gutwika ugakora urwego rwa fosifore rurinda kandi ukarekura umwuka wa aside fosifore.

• Urwego rwo kongeramo rusabwa: Ibice 15–25(ibice kuri buri bice ijana bya resin)
• Kuri PVC isanzwe, kongeramoIbice 20Ubusanzwe, aluminium hypophosphite igera ku gipimo cya V-0 cyo kudakora neza kw'umuriro.
• Ku bijyanye no kugabanya ubushyuhe bw'inkongi, ingano y'inkongi ishobora kongerwa, ariko ingaruka ku miterere y'inkongi zigomba kwitabwaho.
• Amabwiriza yo kwirinda:
• Hypophosphite ikabije ya aluminiyumu ishobora kugabanya imikorere yo gutunganya (urugero, kudakora neza kw'amazi).
• Birasabwa kubivanga n'ibindi bintu bigabanya umuriro (urugero: aside boric, aluminium hydroxide) kugira ngo bigire ingaruka nziza ku mikorere y'uruhererekane rw'ibikoresho.

2. Inyongera y'urwego rwa aside boric

Aside borike ni umuti ugabanya umuriro ku giciro gito, ukora cyane cyane binyuze mu kubora kw'inyuma y'umubiri no gukora urwego rurinda ibintu rumeze nk'ikirahure.

• Urwego rwo kongeramo rusabwa: Ibice 5–15
• Aside borike ikoreshwa nk'ikintu kidakoresha umuriro, kandi ingano irenze urugero ishobora kwangiza imikorere y'ubuhanga n'imikorere y'ibikoresho.
• Muri PVC, kongeramo hirya no hinoIbice 10aside boric ishobora gukorana na hypophosphite ya aluminiyumu kugira ngo yongere ubushyuhe bwo kugabanya umuriro.
• Amabwiriza yo kwirinda:
• Aside ya borike ni hygroscopic, bityo kuyibika no kuyikoresha bigomba kwirinda koroherwa n'ubushuhe.
• Ingaruka zayo zo kudakoresha umuriro ziragabanuka iyo ikoreshejwe yonyine; akenshi ivangwa n'ibindi bintu bigabanya umuriro (urugero: aluminium hypophosphite, aluminium hydroxide).

3. Uburyo bwo guhuza imiterere ya Aluminium Hypophosphite na aside Boric

Kugira ngo ugere ku gipimo cya V-0, aluminium hypophosphite na aside boric bishobora guhuzwa kugira ngo bigire ingaruka nziza. Hasi hari uburyo bwo kubigaragaza:

• Hypophosite ya aluminiyumu: Ibice 15–20
• aside borike: Ibice 5–10
• Izindi nyongeramusaruro:
• Imashini ikora pulasitiki (urugero, DOP): Uko bikenewe (ihindurwa hashingiwe ku bisabwa ku bukomere bwa PVC)
• Igitera imbaraga:Ibice 2–5(urugero, umunyu wa lisansi, ibintu bitera imbaraga calcium-zinc)
• Amavuta yo kwisiga:Igice cya 0.5–1(urugero, aside stearike)

Urugero rw'ikoreshwa ry'ibiyobyabwenge:

• Resin ya PVC:Ibice 100
• Hypophosite ya aluminiyumu:Ibiro 18
• Borate ya zinki:Ibice 8
• Igikoresho cya pulasitiki (DOP):Ibice 40
• Igitera imbaraga:Ibice 3
• Amavuta yo kwisiga:Ibice 0.8

4. Gupima no kunoza imikorere

Mu bikorwa bifatika, intambwe zikurikira zirasabwa kugira ngo habeho isuzuma n'ivugurura:

1. Uburyo bwo gukora ikizamini cy’igerageza:Tegura igerageza rito rishingiye ku byiciro by'ingero.
2. Ikizamini cya UL-94:Kora ibizamini byo gutwika bihagaze kugira ngo urebe niba umuriro udashobora gucika burundu.
3. Isuzuma ry'imikorere:Suzuma imiterere ya mekanike (urugero, imbaraga zo gukurura, imbaraga z'ingaruka) n'imikorere yo gutunganya (urugero, ubushobozi bwo gutemba, ubushyuhe buhamye).
4. Gutunganya:Hindura urugero rw'inyongera ya aluminium hypophosphite na aside boric cyangwa ushyiremo ibindi bintu bigabanya umuriro (urugero: aluminium hydroxide, antimoni trioxide) kugira ngo wongere imikorere.

5. Ibintu by'ingenzi bigomba kwitabwaho

• Ubushyuhe bwo gutunganya:Ubushyuhe bwo kubora bwa aluminium hypophosphite na aside boric buri hejuru cyane; menya neza ko ubushyuhe bwo gutunganya ibintu butarenze iyi mipaka kugira ngo hirindwe kwangirika.
• Gutatana:Menya neza ko ibintu bigabanya umuriro bikwirakwira muri PVC kugira ngo hirindwe ibibazo byo gucukuka kw'umuriro ahantu runaka.
• Ingaruka ku bidukikije:Hypophosphite ya aluminiyumu na aside boric byombi ni ibintu bigabanya umuriro mu buryo butangiza ibidukikije, ariko bigomba kwemezwa ko bihuye n'ibindi bikoresho by'inyongera.

6. Umwanzuro

Kugira ngo ugere ku gipimo cya V-0 cyo kudashira kw'umuriro muri pulasitiki ya PVC ikoreshwa mu gushyushya amashanyarazi, urwego rw'inyongera rwasabwe ni15–25 phr kuri hypophosphite ya aluminiyumuna5–15 phr kuri aside boricGukoresha ibi bintu bigabanya umuriro mu buryo buhuriweho bishobora kongera imikorere. Mu by'ukuri, kunoza imikorere hashingiwe ku miterere yihariye n'ibisabwa mu mikorere ni ngombwa, kandi isuzuma rya UL-94 rigomba gukorwa kugira ngo harebwe niba ibipimo byo kugabanya umuriro ari ukuri.
