Wakaisa vheruvhu yebhora rePVC uye unotarisira kuti ishande kwemakore. Asi kukundikana kamwe kamwe kunogona kukonzera mafashamo, kuparadza midziyo, uye kuvhara mabasa.

A yepamusoro-soroPVC bhora vharafuinogona kugara kusvika kumakore makumi maviri mumamiriro ezvinhu akanaka. Nekudaro, hupenyu hwayo chaihwo hunotarwa nezvinhu zvakaita seUV kufumurwa, kusangana kwemakemikari, tembiricha yemvura, kudzvanywa kwehurongwa, uye kuti inowanzoshandiswa sei.

Nhamba iyoyo yemakore makumi maviri ndiyo yekutanga, kwete vimbiso. Mhinduro chaiyo ndeyekuti "zvinoenderana." Ndaitaura nezvazvo naBudi, maneja wekutenga wandinoshanda naye kuIndonesia. Anoona kuzere. Vamwe vevatengi vake vane mavharuvhu edu anoshanda zvakakwana muhurongwa hwekurima mushure memakore gumi nemashanu. Vamwe, zvinosuruvarisa, vane mavharuvhu akundikana mukati memakore maviri. Musiyano hausi vharuvhu pachayo, asi nharaunda yainogara mairi. Kunzwisisa izvi zvikonzero zvezvakatipoteredza ndiyo nzira chete yekufanotaura kuti vharuvhu yako ichagara kwenguva yakareba sei uye kuve nechokwadi kuti inosvika pakukwanisa kwayo kuzere.

Ndeipi inotarisirwa hupenyu hwePVC bhora vharafu?

Iwe unoda nhamba iri nyore yechirongwa chako cheprojekiti. Asi kusimbisa nguva yako uye bhajeti pakufungidzira kune ngozi, kunyanya kana valve ikakundikana nguva refu usati watarisira.

Hupenyu hunotarisirwa hwevharuvhu yePVC hunobva pamakore mashoma kusvika kumakumi maviri emakore. Izvi hazvina kugadziriswa. Hupenyu hwekupedzisira hunoenderana zvachose nemamiriro ayo ekushanda uye kunaka kwezvinhu zvayo.

Funga nezveupenyu hwevharuvhu setangi rakazara regesi. Iwe unotanga nehuwandu hwemakore makumi maviri. Chero mamiriro akaomarara aunoisa pairi anoshandisa iyo mafuta nekukurumidza. Zvikuru zvinhu imwaranzi yeUV kubva kuchiedza chezuva uye kushandiswa kazhinji. Ivhavha inoiswa kunze pasina dziviriro ichaita brittle seMwaranzi yeUV inoputsa purasitiki yePVC. Pashure pemakore mashomanana, yaigona kuita isina kusimba zvokuti kungogogodzawo zvayo kunogona kuipwanya. Vhuru mufekitari inovhurwa nekuvharwa kane mazana pazuva ichasakara zvisimbiso zvayo zvemukati nekukurumidza kupfuura kuvharwa kwetambo huru kunongotenderedzwa kaviri pagore. Kupisa kwepamusoro, kunyange iyo iri pasi pemuganhu we60 ° C, icharamba ichipfupisa hupenyu hwayo nekufamba kwenguva ichienzaniswa nevhavha munzvimbo inotonhorera, ine rima. Hupenyu hurefu hwechokwadi hunobva mukufananidza aquality vharafukunzvimbo yakapfava.

Mavharuvhu ebhora ePVC anogara kwenguva yakareba sei?

Iwe wakanzwa kuti vanogona kugara kwemakumi emakore. Asi wakaonawo dzimwe dzakatsemuka uye dzakatsvuka mushure memwaka mishoma. Izvi zvinoita kuti zviome kuvimba navo.

Munzvimbo yakadzivirirwa, yakaderera-kushushikana senge mutsara wepombi yemukati, PVC bhora revhavha rinogona kugara nyore kupfuura makore makumi maviri. Nekudaro, kana yakafumurwa kune yakananga zuva uye kushandiswa kwakanyanya, hupenyu hwayo hunoshanda hunogona kutemwa kusvika kumakore 3-5 chete.

Kusiyana uku ndechimwe chinhu chandinokurukura naBudi nguva dzose. Ane mutengi mumwe chete, murimi, akaisa mavharuvhu edu muimba yepombi yakavharirwa yemadiridziro ake makore 15 apfuura. Dzinodzivirirwa kubva kuzuva nemamiriro okunze, uye dzinoshanda zvakakwana nanhasi. Ane mumwe mutengi anoisa pombi dzemadziva epadenga remba. Mapurojekiti ake ekutanga akashandisa mavharuvhu asina kudzivirirwa. Muzuva rinopisa zvikuru rokuIndonesia, mavharuvhu iwayo akatanga kuita matete uye akatanga kusashanda mumakore mana. Yakanga iri chaiyo vharafu yemhando yepamusoro. Musiyano bedzi wakanga uri mhoteredzo. Izvi zvinoratidza kuti mubvunzo hausi wekuti "vhavha inogara kwenguva yakareba sei?" asi “Zvichatora nguva yakareba seimunzvimbo ino chaiyo?” Kuchengetedza PVC valve kubva kune muvengi wayo mukuru, zuva, ndicho chinhu chimwe chete chakakosha chaunogona kuita kuti uve nechokwadi chekuti inosvika pakureba kwayolatex pendikana abhokisi revhavhainogona kuwedzera makore ehupenyu.

Akavimbika sei mavharuvhu ebhora ePVC?

PVC ipurasitiki chete, uye inogona kunzwa isina kusimba pane simbi. Iwe unonetseka kuti inogona kutsemuka kana kudonha pasi pesimba renyika chaiyo, ichiita kuti iite seisingavimbike pane inorema yendarira vharafu.

Yepamusoro-mhando PVC bhora mavharuvhu akavimbika zvakanyanya kune avanoda maapplication. Kuvakwa kwavo kwepurasitiki kunoreva kuti vanodzivirirwa zvachose kune ngura uye mineral buildup izvo zvinoita kuti mavharuvhu esimbi atadze kana kubata nekufamba kwenguva.

Kuvimbika kunopfuura kungoita hutsinye simba; ndezvekuita kunoenderana. Ivhavha yesimbi inotaridzika yakaoma, asi muhurongwa hwemvura zhinji, kuvimbika kwayo kunodzikira nekufamba kwenguva. Zvicherwa zviri mumvura, kana makemikari akaita seklorini, anogona kukonzera ngura uye chiyero kuti zvivake mukati. Izvi zvinoita kuti vharuvhu iome uye inonetsa kutendeuka. Pakupedzisira, inogona kubata zvachose, ichiita kuti isabatsire munjodzi. PVC mavharuvhu haana dambudziko iri. Ivo vane makemikari inert kumvura uye zvinowanzoitika zvinowedzera. Hadzigoni kuita ngura kana kuita ngura. Nzvimbo yemukati inogara yakatsetseka, uye bhora rinoramba richishanduka nyore, kunyange mushure memakore gumi ebasa. Uku ndiko kuvimbika kwechokwadi kwandinotaura kune vatengi veBudi nezvazvo. Kune chero kushandiswa kwemvura inotonhora, kubva kumadziva kusvika pakudiridza kune aquaculture, PVC valve inopa chiyero chenguva refu, kuvimbika kunofungidzirwa kuti simbi kazhinji haigoni kufanana nokuti haigoni kubata.

PVC valve inogara kwenguva yakareba sei?

Vhuru yako yamira kushanda nemazvo. Uri kufunga kuti zvakangosakara kubva mukuchembera here, kana kuti chimwe chinhu chakaita kuti zvikundikane kuitira kuti zvisaitike zvakare.

Hupenyu hwePVC vharuvhu hunopera kana chinhu chakakosha chikatadza. Izvi zvinodaro nguva dzose nekuda kwechimwe chezvinhu zvitatu: zvisimbiso zvakasakara zvemukati, kushatiswa kweUV kunoita kuti muviri uite brittle, kana kukuvadzwa kwemuviri kubva mukusimbisa-kupfuura.

Mavharuvhu haango“fa nokuchembera”; chimwe chikamu chinopa kunze. Kukundikana kwekutanga uye kwakajairika ndiyo zvisimbiso. Mhete chena yePTFE inonamira bhora uye nhema dzeEPDM O-mhete padzinde dzinopera kubva kuzviuru zvematenderedzwa akavhurika nekuvhara. Izvi zvinotungamirira kumvura shoma, ingave kuburikidza nepombi kana kunze kwemubato. Uku ndiko kubvaruka. Kukundikana kwechipiri ndiwo muviri pachawo. UV chiedza chinoita PVC brittle kwemakore. Ivhavhavha inoshanda zvakakwana inogona kuerekana yatsemuka kubva pasando yemvura kana kuita diki. Kukundikana kwechitatu kwakajairika kunoitika panguva yekuisa. Vanhu vanowanzoshandisa simba rakawandisa kana tepi yeshinda pakubatanidza mavharuvhu ane threaded. Izvi zvinogadzira dzvinyiriro huru pamucheto wechikadzi wakarukwa wevhavha, zvichikonzera kutsemuka kwebvudzi kunogona kutadza mavhiki kana mwedzi gare gare. Kunzwisisa aya mamodhi ekutadza kunoratidza kuti hupenyu hwevhavha chinhu chaunokwanisa kushinga kubata nekuwedzera.

Mhedziso

A quality PVC valve inogona kugara kwemakumi emakore. Hupenyu hwayo hunoenderana zvishoma nenguva uye zvakanyanya pakushandiswa kwakakodzera, kuchengetedzwa kubva kuUV mwenje, uye iyo chaiyo system dhizaini yekushandisa kwayo.
