UwitekaUmuyoboro wa PVCformulaire ikubiyemo: PVC resin, guhindura impinduka, stabilisateur, gutunganya ibintu, kuzuza, pigment hamwe namavuta yo hanze.

1. PVC

Kugirango ubone plastike yihuse kandi imwe, uburyo bwo guhagarika bugomba gukoreshwa kugirango urekure resin.

——Ibisigarira bikoreshwa mu miyoboro ibiri yometseho imiyoboro bigomba kuba bifite uburemere bwiza bwa molekile hamwe nibirimo umwanda, kugirango bigabanye “ijisho ry amafi” mu muyoboro kandi wirinde gusenyuka kw'imiyoboro no guturika kw'urukuta rw'imiyoboro.

—— Ibisigarira bikoreshwa mu miyoboro itanga amazi bigomba kuba “urwego rw’isuku”, naho vinyl chloride isigaye muri resin igomba kuba iri muri mg / kg 1.Kugirango hamenyekane ubuziranenge bwumuyoboro no kugabanya igipimo gifite inenge, inkomoko ya resin igomba kuba ihamye.

2. Stabilisateur

Kugeza ubu, ingufu nyamukuru zikoreshwa mu Bushinwa ni: amasabune y'ibyuma, ibyuma byangiza umunyu, ibyuma bidasanzwe byangiza isi, hamwe na tin stabilisateur.

Stabilisateur irimo ibyuma biremereye (nka Pb, Ba, Cd) byangiza ubuzima bwabantu, kandi ingano yiyi stabilisateur mugushinga imiyoboro itanga amazi ni mike.Mubikorwa byo gukuramo umugozi umwe, amateka yo gushyushya ibintu ni maremare kuruta ayo mugikorwa cyo gukuramo impanga, kandi umubare wa stabilisateur wambere wiyongereyeho hejuru ya 25%.Ubushyuhe bwumutwe wumuyoboro wikubye kabiri urukuta rushyizwe hejuru, ibikoresho biguma mumutwe umwanya muremure, kandi ingano ya stabilisateur muri formula irenze iy'ibisanzwe bisanzwe.

3. Uzuza

Uruhare rwuzuza ni ukugabanya ibiciro.Gerageza gukoresha ultra-nziza ikora yuzuza (igiciro kiri hejuru).Umubare wibikoresho byumuyoboro ni munini kuruta uwumwirondoro.Umubare mwinshi wuzuza bizatera ingaruka zo kugabanuka kugabanuka no kurwanya umuvuduko wumuyoboro kugabanuka.Kubwibyo, mumiyoboro yimiti nu miyoboro itanga amazi, ingano yuzuza muri kopi zitarenze 10.Ingano yuzuza umuyoboro wamazi hamwe nimbeho ikonje ikonje irashobora kuba myinshi, kandi umubare wa CPE urashobora kwiyongera kugirango uhindure igabanuka ryimikorere.

Ku miyoboro ifite ibyangombwa bisabwa kugirango imikorere ikorwe, hamwe nimiyoboro yimvura, ubwinshi bwuzuza burashobora kuba bunini, ariko kwambara impanga ya twin-screw birakomeye.

4. Guhindura

(1) Gutunganya impinduka: imiyoboro isanzwe irashobora gukoreshwa gake cyangwa idakoreshwa;imiyoboro isukuye hamwe n'umuyoboro muto-ukikijwe cyane.

.

.Inzira y'umuyoboro ukomeye wa PVC ni pigment, cyane cyane dioxyde ya titanium cyangwa karubone yumukara, ushobora gutoranywa ukurikije ibisabwa bigaragara muri umuyoboro.

5. Guhuza amavuta yo kwisiga hamwe na stabilisateur

(1) Hitamo amavuta yo hanze ahuye ukurikije stabilisateur

a.Organotin stabilisateur.Amabati kama stabilisateur afite aho ahurira neza na PVC, kandi afite imyumvire ikomeye yo gukomera kurukuta rwicyuma.Amavuta ahendutse yo hanze ahuza ni sisitemu ya paraffin-calcium stearate.

b.Kuyobora umunyu.Kurwanya umunyu mwinshi bigira aho bihurira na resin ya PVC, kandi bifata gusa hejuru yubuso bwa PVC, bikabuza guhuza ibice bya PVC.Mubisanzwe, kuyobora stearate-calcium stearate amavuta yo hanze akoreshwa kugirango ahuze.

(2) Ingano yo gusiga hanze.Niba uhinduye umubare wamavuta yo hanze arashobora kutuzuza ibisabwa byo gutunganya ibikoresho, urashobora gutekereza kongeramo amavuta make yimbere.Iyo ingaruka zikomeye zo guhindura ibintu zikoreshwa, kubera ubukonje bwinshi bwo gushonga, amahirwe yo gufatira hejuru yicyuma ni menshi, kandi umubare wamavuta yo hanze ukenera kwiyongera;Umuyoboro wuzuye urukuta rusaba amavuta menshi yo hanze.Iyo ubushyuhe bwo gutunganya buri hejuru, impengamiro yo gushonga kwizirika hejuru yicyuma iba ndende, kandi hongeweho andi mavuta yo hanze.

Nigute imiyoboro ya PVC ikorwa?

Imiyoboro ya PVC ikorwa mugukuramo ibikoresho fatizo PVC, kandi mubisanzwe ukurikiza intambwe imwe yibikorwa bisanzwe byo kuvoma imiyoboro:

• Kugaburira ibikoresho fatizo pellet / ifu muri PVC twin screw extruder
• Gushonga no gushyushya muri zone nyinshi zidasanzwe
• Gukuramo binyuze mu rupfu kugirango ube umuyoboro
• Gukonjesha umuyoboro umeze
• Gukata imiyoboro ya PVC kuburebure bwifuzwa
