Umuyoboro wa PVC (umuyoboro wa PVC-U) umuyoboro ukomeye wa PVC, ukozwe muri resin ya PVC hamwe na stabilisateur, amavuta yo kwisiga hamwe nandi mashanyarazi ashyushye akoreshwa, ni umuyoboro wa pulasitiki wambere wakozwe kandi ushyizwe mubikorwa.Umuyoboro wa PVC-U ufite imbaraga zo kurwanya ruswa, guhuza byoroshye, igiciro gito nuburyo bukomeye.Nyamara, kubera kumeneka kwa PVC-U monomer ninyongeramusaruro, birakwiriye gusa uburyo bwo gutanga amazi aho ubushyuhe bwo gutanga butarenga 45 ℃.Imiyoboro ya plastiki ikoreshwa mugutwara amazi, amazi mabi, imiti, gushyushya no gukonjesha amazi, ibiryo, amazi meza cyane, ibyondo, gaze, umwuka uhumanye hamwe na sisitemu ya vacuum.

Ifite imbaraga zingana kandi zogukomeretsa: ariko guhinduka kwayo ntabwo ari byiza nkindi miyoboro ya plastiki.

Kurwanya amazi make: urukuta rwumuyoboro wa PVC-U ruroroshye cyane, kandi kurwanya amazi ni bito cyane.Coefficient de coiffure ni 0.009 gusa, kandi ubushobozi bwayo bwo gutwara amazi burenze 20% ugereranije nu muyoboro wicyuma wa diameter imwe, naho 40% ugereranije nu muyoboro wa beto.

Kurwanya ruswa nziza no kurwanya ibiyobyabwenge: Umuyoboro wa PVC-U ufite aside irwanya aside, kurwanya alkali no kurwanya ruswa.Ntabwo iterwa nubushuhe nubutaka pH, kandi ntibikeneye uburyo bwo kuvura ruswa mugihe umuyoboro ushyizweho.

Hamwe nogukomera kwamazi meza: kwishyiriraho umuyoboro wa PVC-U bifite amazi meza, byaba bihujwe nimpeta cyangwa reberi.

Bite gihamya: Umuyoboro wa PVC-U ntabwo ari isoko yintungamubiri bityo ntushobora kwibasirwa nimbeba.Nk’uko ubushakashatsi bwakozwe n’ikigo cy’igihugu gishinzwe ubuzima muri Michigan bubitangaza, imbeba ntiziruma umuyoboro wa PVC-U.

Ikizamini cyimikorere: gukiza igihe, igipimo cyo kugabanuka, imbaraga zo kugabana, imbaraga zumutungo wambuye imbaraga, ituze ryumuriro, igihe cyakoreshwa, igihe cyo kubika, kurekura ibintu byangiza.

Inzira yumusaruro

Ibikoresho byoroheje + kwitegura gufasha → kuvanga → gutanga no kugaburira → kugaburira ku gahato → Ubwoko bwa Cone-twin-screw extruder → extrusion mold → ubunini bworoshye → spray vacuum setting box pipe stacking rack → kurangiza ibicuruzwa no gupakira.

PVC irashobora kugabanywamo PVC yoroshye na PVC ikomeye.

PVC ikomeye ifite hafi 2/3 yisoko, na konte yoroshye ya PVC kuri 1/3.

Ubusanzwe PVC ikoreshwa mubutaka, hejuru no hejuru yuruhu, ariko kubera ko PVC yoroshye irimo plasitike (iyi nayo ni itandukaniro riri hagati ya PVC yoroshye na PVC ikomeye), imikorere yumubiri irakennye (kuko imiyoboro yamazi igomba kwihanganira umuvuduko wamazi, yoroshye PVC ntabwo ikwiriye gukoreshwa), bityo imikoreshereze yayo ni mike.

PVC ikomeye ntabwo irimo plasitike, biroroshye rero gukora, ibintu byiza bifatika, bityo ifite iterambere ryinshi nigiciro cyagaciro.Mubikorwa byo gukora ibikoresho bya PVC, inyongeramusaruro nyinshi zigomba kongerwaho, nka stabilisateur, plasitike nibindi.Niba inyongeramusaruro zose zo kurengera ibidukikije zikoreshwa, umuyoboro wa PVC nawo ntabwo ari uburozi kandi butagira uburyohe bwo kurengera ibidukikije.
