PVC SG-5 yepombi,
PVC yekugadzira pombi, PVC SG-5 resin,

Sg-5 resin ine yakaderera dhigirii yepolymerization inofanira kusarudzwa mukugadzirwa kwechubhu yakaoma.Iyo yepamusoro dhigirii yepolymerization, iyo yemuviri uye yemagetsi zvivakwa uye kupisa kuramba
Izvo zvirinani zvivakwa zviri, asi kushata kwemvura yeresin kunounza mamwe matambudziko pakugadzirisa, saka viscosity inowanzo (1).7 ~ 1. 8) x 10-3 pa
• SG-5 resin yeS yakakodzera.Pombi yakaoma inowanzo shandisa lead stabilizer, yayo yakanaka yekudziya kugadzikana, inowanzoshandiswa matatu basic lead, asi iwo
Inowanzo shandiswa nelead uye barium sipo ine lubricity yakanaka.Kusarudzwa uye kushandiswa kwemafuta kwakakosha zvakanyanya pakugadzirisa pombi yakaoma.
Zvese zviri zviviri kunhuwirira kwemukati uye kwekunze kukwirisa kunofanirwa kutariswa kudzikisa intermolecular simba, kuitira kuti kunyunguduka viscosity inogona kuderedzwa pakugadzira, uye kudzivirira kunyungudika.
Namatira kune simbi inopisa kuti ipe nzvimbo yakajeka.Sipo yesimbi inowanzo shandiswa pakuzora mukati, uye wakisi ine nzvimbo yakaderera yekunyungudika inoshandiswa pakuzora kunze.Filler master
Kushandisa calcium carbonate uye barium (barite powder), calcium carbonate inoita kuti kushanda kwepombi kuve kwakanaka, barium inogona kuvandudza kuumbwa, kuitira kuti pombi ive nyore kugadzira, maviri.
Mari yacho inogona kuderedzwa, asi yakawandisa ichakanganisa mashandiro epombi, pombi yekumanikidza uye pombi isingadziviriri pombi zvaive nani kusawedzera kana kuwedzera zvishoma filler.

Chii chinonzi PVC uye CPVC Mapaipi?

PVC mapaipi

Yakagadzirwa muma1930s, mapaipi ePVC (polyvinyl chloride) ave chiyero chepombi yemanisipala nemaindasitiri pasirese.MuUS, zvikamu zvitatu muzvina zvedzimba dzese dzinoshandisa PVC.Kubva kuma1950, yave yakajairika kutsiva mapaipi esimbi

PVC inogadzirwa uchishandisa imwe yematatu mapolymerization maitiro: kumiswa polymerization, emulsion polymerization, kana kuwanda polymerization.Iyo yakawanda yePVC inogadzirwa uchishandisa kuturika polymerization.

Zvakakosha kuziva kuti mapaipi ePVC anouya mumhando mbiri: yakaoma uye isina purasitiki.Iyo fomu yakaoma ingangove yekutanga kuuya mupfungwa- funga mvura inonwiwa, pombi dzemvura, tsvina, uye kurima.Iyo unplasticized fomu inochinjika, iyo yakanaka kuti ishandiswe mumashandisirwo akadai sekurapa tubing uye insulation yewaya dzemagetsi.

Zvimwe zvakanakira PVC pombi zvinosanganisira simba rayo, yakakwirira durability, yakaderera mutengo, nyore kugadzwa, uye kuramba ngura uye ngura.

CPVC Mapaipi

CPVC inonyanya PVC iyo yakave neklorini.Iyo chlorination process inobvumira CPVC kushingirira tembiricha yepamusoro-kusvika 200°F-uye inonatsiridza moto wayo nekusaita ngura.Nekuda kwekupikiswa kwayo kwekushisa kwakanyanya, macode mazhinji ekuvaka anoda mapaipi eCPVC ekushandisa mvura inopisa, asi inogona kushandiswa kune ese ari maviri anopisa uye anotonhora mvura inonwiwa.Pamusoro pezvo, CPVC inosanganisirwa zvakanyanya mukushandiswa kwemasisitimu ekuisa moto.

Rondedzero yeCPVC zvakanakira inowedzera.Kune imwe, makemikari ayo uye tembiricha kuramba inoita kuti igare yakasimba uye inovimbisa hupenyu hurefu.

Nekuda kwekugona kwayo kumira tembiricha yakakwira uye huwandu hwayo hwakawanda hwekutengesa uye maindasitiri ekushandisa, CPVC inouya pamutengo wepamusoro pane PVC.

Ndeupi musiyano uripo pakati pePVC neCPVC mapaipi?

Musiyano mukuru pakati pePVC neCPVC kugona kwavo kutsungirira tembiricha.Sezvambotaurwa, CPVC pombi inogona kumira kusvika ku200 ° F, nepo PVC pombi inogona kushivirira kusvika ku140 ° F.Kana iwe ukaenda pamusoro peiyo tembiricha, ese ari maviri anotanga kupfava, izvo zvinogona kuita kuti majoini ashaye simba uye mapaipi atadze.Nekuda kweizvozvo, maplumbers mazhinji achakurudzira kuti ushandise CPVC yemitsara yemvura inopisa uye PVC yemitsara yemvura inotonhora.

Kunyange zvazvo PVC ine zvakawanda zvakanaka, CPVC ine flexible hukuru, uye inowanikwa mune zvose mazita epombi saizi (NPS) uye saizi yemhangura yechubhu (CTS).Mukupesana, PVC inongowanikwa muNPS system.Mapombi ese ari maviri anowanikwa mu10 ft uye 20 ft kureba.

Panyaya yechitarisiko, mapaipi ePVC machena kana rima grey muruvara, uye mapaipi eCPVC anowanzo chena, grey, kana yero.Kana paine mubvunzo chero upi zvawo, ese ari maviri achange aine hunyanzvi hwavo hwakadhindwa padivi.Sezvo kuumbwa kwemakemikari kuchisiyana pakati pezviviri, zvinonyungudutsa simiti uye zvisungo zvekubatanidza hazvifanirwe kushandiswa zvakasiyana.

Ndezvipi zvakafanana pakati pePVC neCPVC mapaipi?

Kana zvasvika kune tekinoroji uye yemuviri kufanana, ese PVC neCPVC ane inonakidza runyorwa rwezvakanakira.Kune imwe, zvimiro zvemapombi ese ari maviri anovabvumira kuramba kuonda uye kuora kubva kumakemikari.Chechipiri, ese ari maviri akachengeteka kushandisa nemvura inonwiwa kana ANSI / NSF 61 yakasimbiswa.Ose anouya muChirongwa 40 uye Schedule 80 ukobvu, uye anowanikwa mumagumo uye bhero kupera.Pamusoro pezvo, Chirongwa makumi mana PVS chinouya muClass 125 fittings.

Sebhonasi yakawedzerwa kune yavo nyore yekuisa maitiro, ese ari maviri akanyanya kusimba uye akasimba, achibvumira hupenyu hwemakore makumi mashanu kusvika makumi manomwe.Uye kusiyana nemhangura, mutengo wemapombi ePVC neCPVC haubvi pamutengo wemusika.

PVC resin inogona kugadziriswa kuva akasiyana epurasitiki zvigadzirwa.Inogona kukamurwa kuita zvigadzirwa zvinyoro uye zvakaoma maererano nekushandiswa kwayo.Inonyanya kushandiswa kugadzira mapepa akajeka, pombi fittings, makadhi egoridhe, midziyo yekuisira ropa, machubhu akapfava uye akaomarara, ndiro, magonhi nemahwindo.Profiles, mafirimu, magetsi ekudzivirira zvinhu, tambo jaketi, kuwedzerwa ropa, nezvimwe.

Kudiwa kwePVC kunofambiswa neZvigadzirwa, Zvekurima, Packaging uye Consumer Sectors zvigadzirwa.Mumusika wepamba PVC resin inoshandiswa kugadzira zvinhu zvakaoma uye zvakapfava zvePVC zvakapedzwa.Inenge 55% yemugove wemusika unobatwa nePVC Pipes & Fittings segment chete, zvimwe zvikamu zvinosanganisira Firimu & Sheet, Cable Compound, Flexible hose, Shoes, Profile, Flooring uye Foam Board.Mumusika wepamba wePVC, resin inonyanya kushandiswa kugadzira mapaipi ePVC.Inenge 55% yekushandiswa kweresin iri muchikamu ichi chete.Mamwe masangano anosanganisira matehwe ekugadzira, shangu, mashizha akaoma uye akapfava, hosi yebindu, mahwindo nemagonhi nezvimwewo. PVC yemba yekutengesa vhoriyamu iri kuramba ichiwedzera pachiyero che5% pagore.
