Ibibazo nibisubizo mugukora imyirondoro ya PVC

Dukora cyane cyane ikibaho cya PVC,inkuta, urukuta rwa WPC, Windows, imashini yimashini.

Nkuko twese tubizi, PVC (polyvinyl chloride) ni plastiki itumva ubushyuhe, kandi itara ryayo naryo rirakennye.Mubikorwa byubushyuhe numucyo, biroroshye kubyitwaramo de-HCl, bakunze kwita kwangirika.Ingaruka zo gutesha agaciro nuko imbaraga zibicuruzwa bya pulasitike bigabanuka, ibara ryamabara, numurongo wumukara ugaragara, kandi mubihe bikomeye, ibicuruzwa bitakaza agaciro kabyo.Ibintu bigira ingaruka mbi ku kwangirika kwa PVC harimo imiterere ya polymer, ubwiza bwa polymer, sisitemu yo gutuza, gushushanya ubushyuhe nibindi.Ukurikije ubunararibonye, ​​umuhondo wumwirondoro wa PVC ahanini biterwa na paste ipfuye.Impamvu nuko umuyoboro utemba wurupfu udafite ishingiro cyangwa polishinge yaho mumiyoboro itemba ntabwo ari nziza, kandi hari ahantu hahagaze.Umurongo wumuhondo wa PVC imyirondoro ahanini wanditse muri barri ya mashini.Impamvu nyamukuru nuko hariho inguni yapfuye hagati yamasahani (cyangwa amaboko yinzibacyuho), kandi ibintu bitagenda neza.Niba umurongo wumuhondo ugororotse ugororotse kuri profili ya PVC, ibikoresho bihagaze biri gusohoka kwurupfu;niba umurongo wumuhondo utagororotse, ni muburyo bwinzibacyuho.Niba umurongo wumuhondo nawo ugaragara mugihe amata nibikoresho fatizo bidahindutse, impamvu igomba kuboneka cyane cyane muburyo bwa mashini, kandi aho itangirira kubora igomba kuboneka no kuvaho.Niba impamvu idashobora kuboneka uhereye kumiterere yubukanishi, hakwiye kurebwa ko hari ikibazo muburyo cyangwa inzira.Ingamba zo kwirinda gutesha agaciro zirimo ibintu bikurikira:

(1) Kugenzura byimazeyo ibipimo bya tekiniki y'ibikoresho fatizo, no gukoresha ibikoresho bibisi byujuje ibyangombwa;

(2) Gutegura uburyo bwiza bwo kubumba, aho ibikoresho bya PVC bitoroshye gutesha agaciro;

.umuyoboro utemba ugomba gutondekwa kandi ubereye muburebure;igikoresho gishyushya kigomba kunozwa, ibyiyumvo byibikoresho byerekana ubushyuhe hamwe nuburyo bwa sisitemu yo gukonjesha bigomba kunozwa.

kugoreka

Kwunama no guhindura imyirondoro ya PVC nikibazo gikunze kugaragara mugikorwa cyo gukuramo.Impamvu ni: gusohoka kutaringaniye mu rupfu;gukonjesha kudahagije ibikoresho mugihe cyo gukonjesha no gushiraho, hamwe no kugabanuka nyuma yo kugabanuka;ibikoresho n'ibindi bintu

Kwibanda hamwe nuburinganire bwumurongo wose wa extruder nibyo bisabwa kugirango dukemure ihindagurika ryimiterere ya profili ya PVC.Kubwibyo, kwibanda hamwe nuburinganire bwa extruder, gupfa, kalibibasi bipfa, ikigega cyamazi, nibindi bigomba gukosorwa igihe cyose ifumbire isimbuwe.Muri byo, kwemeza ko urupfu rusohoka kimwe nurufunguzo rwo gukemura imyirondoro ya PVC.Urupfu rugomba gukusanyirizwa hamwe mbere yo gutangira imashini, kandi icyuho kiri hagati ya buri gice kigomba kuba gihamye.Hindura ubushyuhe bwo gupfa.Niba ihinduka ritemewe, urwego rwa plastike yibikoresho rugomba kongerwa muburyo bukwiye.Guhindura abafasha Guhindura impamyabumenyi ya vacuum na sisitemu yo gukonjesha uburyo bwo gushiraho nuburyo bukenewe bwo gukemura ihinduka ryimiterere ya PVC.Ingano y'amazi akonje kuruhande rwumwirondoro ufite imihangayiko ikwiye kwiyongera;uburyo bwa mashini ya offset ya centre ikoreshwa muguhindura, ni ukuvuga, muguhindura mugihe utanga umusaruro Ibirindiro bihagaze hagati ya kalibibasi bipfa guhindurwa buhoro buhoro ukurikije icyerekezo cyunamye cyumwirondoro (kwitonda bigomba gukoreshwa mugihe ukoresheje ubu buryo, n'amafaranga yo guhindura ntagomba kuba manini cyane).Kwitondera kubungabunga ibumba nigipimo cyiza cyo gukumira.Ugomba kwitondera cyane ubwiza bwakazi bwibibumbano, kandi ukabungabunga kandi ukabungabunga igihe icyo aricyo cyose ukurikije uko ibintu bimeze.

Mugihe ufashe ingamba zavuzwe haruguru, guhindura imiterere yumwirondoro birashobora kuvaho, kandi extruder irashobora kwemezwa kubyara imyirondoro myiza ya PVC ihamye kandi mubisanzwe.

Ubushyuhe buke bugira ingaruka

Ibintu bigira ingaruka ku bushyuhe buke bwubushyuhe bwimyirondoro ya PVC harimo formula, imiterere yumurongo wigice, imiterere, urwego rwa plastike, imiterere yikizamini, nibindi.

(1) Inzira

Kugeza ubu, CPE ikoreshwa cyane nkimpinduka.Muri byo, CPE ifite igice kinini cya 36% ya chlorine igira ingaruka nziza zo guhindura PVC, kandi dosiye ni ibice 8-12 kubwinshi.Ubworoherane no guhuza na PVC.

(2) Imiterere yumurongo wumwirondoro

Umwirondoro wohejuru wa PVC ufite imiterere myiza yambukiranya ibice.Muri rusange, imiterere ifite uduce duto duto twiza kuruta imiterere ifite igice kinini cyambukiranya, kandi umwanya wo gushimangira imbere kumurongo wambukiranya ugomba gushyirwaho uko bikwiye.Kongera umubyimba wurubavu rwimbere no gufata uruziga ruzengurutse uruziga hagati yimbavu yimbere nurukuta byose bifasha kuzamura imbaraga zubushyuhe buke.

(3) Ibishushanyo

Ingaruka zububiko ku mbaraga zubushyuhe buke bugaragarira cyane cyane kumuvuduko ushonga no kugenzura imihangayiko mugihe cyo gukonja.Iyo resept imaze kugenwa, umuvuduko wo gushonga ufitanye isano cyane no gupfa.Imyirondoro isohoka mu rupfu izabyara impungenge zitandukanye binyuze muburyo butandukanye bwo gukonjesha.Ubushyuhe buke bugira ingaruka kumwirondoro wa PVC burakennye aho guhangayikishwa cyane.Iyo imyirondoro ya PVC ikorewe ubukonje bwihuse, bakunda guhangayika cyane.Kubwibyo, imiterere yumuyoboro wamazi akonje ya kalibibasi ni ingenzi cyane.Ubushyuhe bwamazi bugenzurwa kuri 14 ° C-16 ° C.Uburyo bwo gukonjesha buhoro ningirakamaro mugutezimbere ubushyuhe buke bwubushyuhe bwa profili ya PVC.

Kugirango umenye neza imiterere, isuku ipfa buri gihe kugirango wirinde umwanda wugarije urupfu bitewe nigihe kirekire cyumusaruro uhoraho, bigatuma umusaruro ugabanuka hamwe nimbavu zoroheje zifasha imbaraga zubushyuhe buke.Gusukura buri gihe muburyo bwa kalibibasi birashobora gutuma habaho ihindagurika ryuzuye ryamazi n’amazi y’amazi ya kalibibasi kugirango habeho gukonja bihagije mugihe cyo gukora umwirondoro, kugabanya inenge no kugabanya imihangayiko yimbere.

(4) Impamyabumenyi ya plastike

Umubare munini wubushakashatsi nibisubizo byerekana ko agaciro keza k’ubushyuhe buke bw’ingaruka za PVC imyirondoro iboneka iyo urwego rwa plastike ari 60% -70%.Ubunararibonye bwerekana ko "ubushyuhe bwo hejuru n'umuvuduko muke" na "ubushyuhe buke n'umuvuduko mwinshi" bishobora kubona urugero rumwe rwa plastike.Nyamara, ubushyuhe buke n'umuvuduko mwinshi bigomba gutoranywa mu musaruro, kubera ko ingufu zishyushya zishobora kugabanuka ku bushyuhe buke, kandi umusaruro ukaba ushobora kunozwa ku muvuduko mwinshi, kandi ingaruka zo kogosha zigaragara iyo extruder ikozwe hanze. ku muvuduko mwinshi.

(5) Ibizamini

GB / T8814-2004 ifite amategeko akomeye kubizamini byubushyuhe buke, nkuburebure bwumwirondoro, igitonyanga cyinyundo, radiyo ya nyundo, icyitegererezo cyo gukonjesha, ibidukikije, nibindi. gukurikizwa rwose.

Muri byo: "ingaruka z'uburemere bwagabanutse hagati y'icyitegererezo" zigomba kumvikana nk "" ingaruka zo kugabanuka kugabanuka hagati mu cyuho cy'icyitegererezo ", ibisubizo nk'ibi ni ukuri.

Ingamba zo kunoza imikorere yubushyuhe buke nuburyo bukurikira:

1. Kugenzura neza ubuziranenge bwibikoresho byakoreshejwe, kandi witondere cyane uko ibintu byifashe byasohotse nicyambu cya vacuum.Isohora ry'urupfu rigomba kuba rifite ibara rimwe, rikagira urumuri runaka, kandi gusohoka bigomba kuba bimwe.Igomba kugira elastique nziza mugihe ukaranze intoki.Ibikoresho ku cyambu cya vacuum ya moteri nkuru iri muri "ibisigazwa byibishyimbo", kandi ntibishobora gutanga urumuri mugihe byabanje gushyirwaho plastike.Ibipimo nka moteri nyamukuru ya moteri nigitutu cyumutwe bigomba kuba bihamye.

2.Guhindura uburyo bwo kugenzura kugirango umenye ingaruka za plastike.Kugenzura ubushyuhe bigomba kuba inzira "ibase".Ubushyuhe bwo guhinduka buva muri zone yambere ya extruder kugeza kumutwe bigomba kuba ubwoko bwa "basin".Hindura kuri "imbere ninyuma" kugirango urebe ko ibikoresho bishyushye neza.Mugihe cya formula imwe, inzira yo gukuramo ntigomba guhinduka cyane.
