Iriburiro ryumwotsi muke PVC Umuyoboro hamwe ninsinga

Umwotsi muke PVC (Polyvinyl Chloride) insinga hamwe nu mugozi nibikoresho byihariye bya termoplastique bigamije kugabanya umwotsi n’ibyuka bihumanya ikirere mugihe cyo gutwikwa. Ibi bituma bahitamo byingenzi mubisabwa aho umutekano wumuriro wibanze. Mubisanzwe bikoreshwa mugukingira no kwambika insinga z'amashanyarazi, ibyo bikoresho bitanga ibintu byinshi byingenzi:

Ibigize:Umwotsi muke wa PVC wakozwe hamwe nuruvange rwa PVC, plasitike (nka dioctyl phthalate na tri-2-ethylhexyl trimellitate), retardants yumuriro (urugero: antimoni trioxide, aluminium trihydrate, na zinc borate), stabilisateur (calcium / zinc-ishingiye kuri calcium), hamwe na lisiti (calcium karubone).

Umwotsi muke:Bitandukanye na PVC isanzwe, ishobora kugabanya kugaragara kugeza kuri 90% muminota 30 gusa kubera umwotsi mwinshi, ibicanwa byumwotsi muke wa PVC byakozwe kugirango byuzuze ibipimo byumutekano nka BS EN 61034.Iyi mvange ituma byibura 60% byorohereza urumuri mugihe cyo gutwikwa, bigateza imbere umutekano cyane.

Ikirimi cy'umuriro: PVC isanzwe ifite flame-retardant bitewe na chlorine yayo, ikongerwaho ninyongera ya flame retardant. Ibi bikoresho byujuje ubuziranenge nka IEC 60332-1-2, UL VW1, na E84 (urutonde rwo gukwirakwiza urumuri <25, umwotsi wateje imbere <50).

 Porogaramu:Bikunze gukoreshwa ahantu hashobora kwibasirwa cyane nkibigo byamakuru, tunel, indege, gari ya moshi, hamwe ninyubako rusange, umwotsi muke wa PVC hamwe ninsinga za kabili nibyingenzi mukugabanya ingaruka ziterwa numwotsi numwotsi wuburozi mugihe habaye umuriro.

Ibisanzwe Gutunganya Ibibazo nigisubizo cyumwotsi muke wa PVC Umuyoboro hamwe ninsinga

Gutunganya umwotsi muke wa PVC bikubiyemo gucunga ibibazo bitandukanye, cyane cyane bitewe nuburyo bukomeye. Hasi, turaganira kubibazo bimwe na bimwe bikunze gutunganywa nibisubizo byabyo:

1. Ibirimo Byuzuye Byuzuye biganisha ku kugenda nabi na Torque ndende

Ikibazo:Kugirango ugere ku mwotsi muke, ibice bya PVC akenshi birimo urwego rwinshi rwuzuza ibintu nka organique nka aluminium trihydrate (ATH) cyangwa hydroxide ya magnesium (Mg (OH) ₂) - mubisanzwe 20-60% kuburemere. Mugihe ibyo byuzuza bigabanya umwotsi numuriro, birashobora kongera ubukonje, kugabanya umuvuduko, no gutera ibikoresho kwambara.

Ibisubizo:

Shyiramo ibikoresho byo gutunganya nk'imbere / hanze yo kwisiga (urugero, calcium stearate, ibishashara bya polyethylene, cyangwasilicone) kuri 0.5-2.0 interuro kugirango igabanye ubukonje no kongera umuvuduko.

Koresha igipimo kinini cya L / D twin-screw extruders kugirango utezimbere kuvanga no kuzuza.

Koresha sisitemu ya knader hamwe nimbaraga zo kugaburira kugirango zegeranye.

Hitamo ibyuzuza hamwe nubunini bugenzurwa hamwe nubuvuzi bwo hejuru kugirango utezimbere kandi ugabanye abrasion.

2. Guhagarara neza

Ikibazo:PVC irashobora gutesha agaciro mugihe cyo kuyitunganya, cyane cyane hamwe nuzuza ibintu byinshi hamwe na flame-retardant imizigo, ikarekura gaze ya hydrogène chloride (HCl) itera kwangirika kwibintu, amabara, hamwe nibikoresho byangirika.

Ibisubizo:

Ongeramo stabilisateur yubushyuhe nka calcium / zinc-stabilisateur kuri 2-4 interuro kugirango ubuze HCl kandi wirinde kwangirika.

Koresha amavuta ya soya ya epoxisize (ESO) nka co-stabilisateur kugirango utezimbere ubushyuhe nifoto.

Kugenzura ubushyuhe butunganijwe neza (160-190 ° C) kugirango wirinde ubushyuhe bukabije.

Shyiramo antioxydants ya fenolike (urugero, Bisphenol A kuri 0.3-0.5%) kugirango wongere imbaraga zo gusaza mugihe cyo gutunganya.

3. Kwimuka kwa plastike

Ikibazo:Plastiseri ikoreshwa mugutezimbere guhinduka irashobora kwimuka munsi yubushyuhe bwinshi (urugero, mubigo byamakuru), biganisha ku kwiyubaka gusigaye bishobora kubangamira itumanaho cyangwa kugabanya kuramba.

Ibisubizo:

Koresha plasitike yimuka itimuka aho gukoresha monomeric (urugero, DOP, DINP) kugirango ugabanye kwimuka.

Tegura formulaire "nta-fluide", nkuko byakozwe na OTECH, kugirango wirinde kwimuka kwa plastike mubushuhe bwo hejuru.

Hitamo plasitike nka TOTM, ifite ihindagurika rito kandi irakwiriye kubushyuhe bwo hejuru.

4. Kuringaniza umuriro no guhagarika umwotsi

Ikibazo:Kwiyongera k'umuriro ukoresheje inyongeramusaruro nka antimoni trioxide (3-5%) cyangwa ibivangwa na bromine (12-15%) birashobora kongera imyuka ihumanya umwotsi, bikagorana kuringaniza imitungo yombi. Mu buryo nk'ubwo, ibyuzuye nka calcium karubone birashobora kugabanya umwotsi ariko birashobora kugabanya igipimo cya ogisijeni, bikagira ingaruka ku gucana umuriro.

Ibisubizo:

Koresha ikomatanya rya flame retardant ikomatanya (urugero, ATH hamwe na zinc borate) kugirango uhindure umuriro mwinshi hamwe no guhagarika umwotsi. ATH, kurugero, irekura imyuka yamazi kugirango ihungabanye umuriro kandi ikore urwego rukingira char igabanya umwotsi.

Gabanya imizigo ya CaCO₃ kugeza kuri 20-40 kugirango ugereranye hagati yikiguzi, guhagarika umwotsi, no kutagira umuriro, kuko umubare munini ushobora kugabanya igipimo cya ogisijeni.

Shakisha uburyo bwa PVC bushobora guhuzwa, nk'imirasire ihuza PVC, kugirango uzamure umuriro udashingiye cyane ku nyongeramusaruro.

5. Gutunganyirizwa hamwe nubuziranenge bwubuso

Ikibazo:Ibintu byinshi byuzuza nibindi byongerwaho bishobora kuganisha ku buso bubi kurangiza, gupfa gutonyanga, no gukuramo ibintu bidahuye, bigira ingaruka kumiterere no mumikorere yibicuruzwa byanyuma.

Ibisubizo:KoreshaSILIKE Ifu ya silicone Ifu LYSI-100A. Ibisilicone ishingiye ku nyongeramusaruroni Byakoreshejwe Nkauburyo bwiza bwo gutunganya amavutakuri sisitemu ya PVC ihuza resin kugirango itezimbere imitunganyirize nubuziranenge bwubuso. Nka resin nziza yo gutembera, kuzuza ibicuruzwa no kurekura, torque ya extruder, hamwe na coefficient yo hasi yo guterana amagambo, mar mar, hamwe no kurwanya abrasion…

Inyungu zingenzi za puderi ya silicone LYSI-100A kubintu bya PVC nibicuruzwa byanyuma:

1) Umwotsi muke wa PVC insinga hamwe nibikoresho bya kabili: gusohora bihamye, umuvuduko muke wo gupfa, hejuru ya wire & kabel.

2) Ubuvanganzo buke bwa PVC insinga na kabili: Coefficient de Friction, ibyiyumvo byigihe kirekire.

3) Igicuruzwa cya PVC cyihanganira: Kurwanya-gushushanya, nko muri shitingi ya PVC.

4) Umwirondoro wa PVC: kuzuza neza no kubumba, nta flash ibumba.

5) Umuyoboro wa PVC: umuvuduko wo gusohora byihuse, kugabanya COF, kunoza ubuso bworoshye, no kuzigama ikiguzi.

Niba uhuye nibibazo hamwe no gutunganya ibice bya PVC hamwe nubusembwa bwubuso, cyangwa uhanganye numwotsi muke wa PVC hamwe nogutunganya insinga, geragezaLYSI-100A Ifu ya Silicone kugirango ikorwe neza kandi neza.
