Ndeipi iri nani pane PVC, UPVC, kana CPVC?

Unoona PVC, UPVC, uye CPVC zvakanyorwa pamapepa espec. Zvinotaridzika zvakafanana, asi mitengo yakasiyana. Kusarudza zvisirizvo kunogona kureva kuti unotenga vharuvhu isina simba kana inodhura zvisina kufanira pabasa racho.

CPVC iri nani pamvura inopisa uye inodzivirira makemikari zvakanyanya. Pamapaipi nemavharuvhu, PVC neUPVC zvakafanana—chinhu chakasimba, chakasimba chakakwana pakushandiswa kwemvura inotonhora.

Ngatitsanangure pfungwa yakajairika yekuvhiringidzika. Patinotaura nezvemapaipi nemavharuvhu kuPntek, "PVC" zvinoreva chaizvo "UPVC" (Unplasticized Polyvinyl Chloride). Ndiyo purasitiki yakasimba uye inogara kwenguva refu yaunoona kwese kwese. Saka, haufanirwe kusarudza pakati padzo; dzakafanana pazvinangwa zvedu. Sarudzo chaiyo iri pakati pePVC neCPVC. "C" muCPVC inomiririra Chlorinated. Danho rekuwedzera mukugadzirwa kwayo rinowedzera chlorine yakawanda kuchimiro chezvinhu. Kuchinja uku kuri nyore ndiko kunoita kuti CPVC ive nemabhenefiti maviri makuru: inogona kubata tembiricha yakakwira, uye inogona kuramba mhando dzakasiyana dzemakemikari, kunyanya acids nemabhesi. Saka, kana basa racho richisanganisira mvura inotonhora chete, PVC ndiyo sarudzo inodhura zvakanyanya. Kana paine makemikari anodziya kana ane simba, CPVC ndiyo sarudzo iri nani uye yakachengeteka.

Chinangwa chevharuvhu yebhora yeCPVC ndechei?

Mutengi wako anoda vharuvhu yekuisa mvura inopisa mufekitori kana mumba. Vharuvhu chena yePVC yakajairika inogona kupfava, kupeta, uye kutadza kushanda, zvichikonzera kudonha kwemvura uye kusagadzikana kwesystem.

Chinangwa chikuru chevharuvhu yebhora yeCPVC ndechekubata mvura zvakachengeteka pakupisa kwakanyanya kupfuura zvinogona kutsungirira PVC yakajairwa. Yakagadzirirwa kuparadzirwa kwemvura inopisa uye mitsetse yemvura inokuvadza yemumaindasitiri.

Funga nezve CPVC semhando yepamusoro yePVC. Basa rayo guru nderekushanda panzvimbo dzisingakwanise kushandiswa nePVC. Mavharuvhu ePVC akajairwa haafanirwe kushandiswa chero chinhu chiri pamusoro pe60°C (140°F). Pamusoro pekupisa ikoko, chinhu chacho chinonyorova uye chinorasikirwa nekukwanisa kwacho kubata kumanikidzwa. CPVC, kune rumwe rutivi, inoshanda zvakanaka kusvika 93°C (200°F). Izvi zvinoita kuti ive chinhu chakajairika chepombi dzemvura inopisa neinotonhora muzvivakwa zvekugara uye zvemabhizinesi. Kusagona kwayo makemikari zvakanyanya zvinorevawo kuti isarudzo yakanaka yenzvimbo dzekuchenesa mvura, mafekitori ekugadzirisa makemikari, uye mashandisirwo emaindasitiri uko mvura yacho ingave yakanyanya kusimba yePVC. Unoshandisa aVharuvhu yeCPVCkana uchida kuvimbisa kushanda zvakanaka uye kuchengetedzeka pasi pekupisa nekumanikidzwa nemakemikari.

Mavharuvhu ebhora ePVC anogona kubata kumanikidzwa kwakanyanya here?

Unofanira kusarudza vharuvhu yemuchina wekudiridza unoyerera mvura yakawanda. Unotya kuti vharuvhu yepurasitiki ingasasimba zvakakwana uye inogona kukanganiswa nekushanda kwemuchina wacho.

Ehe,Mavharuvhu ebhora ePVCdzakagadzirirwa kumanikidzwa kwakanyanya. Chiyero chavo chaicho, chakadai sePN10 kana PN16, chinoratidza kuti vanogona kubata 10 kana 16 bar yekumanikidzwa, asi chiyero ichi chinoderera sezvo tembiricha yemvura ichiwedzera.

Iyi ipfungwa inokosha yekunzwisisa kuti ive yakachengeteka. Vharuvhu yebhora yePN16 PVC yakayerwa kuti ikwanise kubata 16 bar (inenge 232 PSI) yekumanikidzwa, izvo zvakakwana kune akawanda mashandisirwo emvura. Zvisinei, chiyero ichi ndechemvura patembiricha yemumba (inenge 20°C). Sezvo tembiricha yemvura iri mukati mepombi ichikwira, chinhu chePVC chinova chakapfava zvishoma, uye kugona kwayo kutsungirira kumanikidzwa kunodzikira. Semuenzaniso, pa40°C, vharuvhu imwechete yePN16 ingangove yakachengeteka kushandisa pa10 bar. Pa60°C, huwandu hwayo hwepamusorokuderedzwa kwechiyero chekumanikidzwakusvika pamabhawa mana. Ndokusaka usingafanire kushandisa mavharuvhu ePVC pamvura inopisa yakamanikidzwa. Kune masisitimu ekudiridza ane simba repamusoro anoshanda nevatengi veBudi, ayo anoshandisa mvura inotonhora kana tembiricha yekunze, chiyero cheduMavharuvhu ebhora ePVC ePN16dzakasimba zvakakwana uye dzakavimbika.

Sei CPVC ichidhura kupfuura PVC?

Uri kugadzirira mutengo wemutengi uye uchaona kuti mavharuvhu eCPVC anodhura kupfuura ePVC. Mutengi wako ari kubvunza kuti sei achifanira kubhadhara mari yekuwedzera yevharuvhu inotaridzika zvakafanana.

CPVC inodhura zvakanyanya nekuti inopfuura nedanho rekuwedzera rekugadzira rinoda simba rakawanda rinonzikucheneswa kwechlorineMaitiro aya anowedzera mutengo asi anoguma nechinhu chakanaka chinogona kubata kupisa kwakanyanya uye makemikari akawanda.

Musiyano wemutengo unobva pakugadzirwa kwezvinhu. Zvinhu zvese zvinotanga sePVC resin. Kuti tigadzire CPVC, tinofanira kutora PVC iyoyo toipinza mumakemikari akaomarara kuti timanikidze maatomu akawanda echlorine mumaketani epolymer. Maitiro aya anoda michina yakasarudzika, zvimwe zvinhu (chlorine), uye simba rakawanda. Hausi kungobhadhara ruvara rwakasiyana rwepurasitiki; uri kubhadhara mainjiniya epamusoro. Ndinogara ndichiudza Budi kuti atsanangure vatengi vake semari yekudyara mukuchengetedza uye kuvimbika. Mari yekuwedzera yevharuvhu yeCPVC idiki kana tichienzanisa nemari yekukuvara, nguva yekushanda, uye kugadzirisa kwaizoitika kana vakashandisa vharuvhu yePVC yakachipa mukushandiswa kwemvura inopisa uko inovimbiswa kuti ichakundikana. Inyaya yekare yekubhadhara mari shoma kune chishandiso chakakodzera chebasa racho.

PVC, CPVC, uye PP zvinoenzaniswa sei padivi nepadivi?

Unoda ruzivo rwekukurumidza kuti uenzanise zvinhu izvi zvakananga. Kuchinja-chinja mapepa ezvigadzirwa zvakasiyana kunovhiringidza uye kunopedza nguva kana uchida mhinduro yekukurumidza yemutengi.

Tafura iyi inopa kuenzanisa kwakajeka kwePVC, CPVC, uye PP muzvinhu zvakakosha. Inokubatsira kusarudza zvinhu zvakakodzera zvekushandisa kwako nekukurumidza, zvichiita kuti vharuvhu ienderane nebasa racho.

Kuti zvinhu zvive nyore kuna Budi nechikwata chake, ndakagadzira bepa iri rekunyepedzera. Ndiyo nzira inokurumidza yekuenzanisa zvinhu zvatakurukura uye kuisa Polypropylene (PP), imwe sarudzo yakakosha. PP inozivikanwa nekudzivirira kwayo makemikari zvakanaka, kunyanya kune zvinonyungudutsa, uye kugara kwayo kwenguva refu. Isarudzo yakanaka kune maindasitiri uye mashandisirwo emhando yepamusoro yechikafu.
