Nhanganyaya
Seimwe yezvigadzirwa zvekuvandudza tekinoroji, mapaipi ePVC anogona kuwanikwa muhupenyu hwezuva nezuva.Mapaipi ePVC anotambirwa zvakanaka nenharaunda yeinjiniya nekuda kwehuremu hwawo huremu, corrosion resistance, high pressure simba uye kuchengeteka uye nyore.Mumakore achangopfuura, pasi pesimba rekusimudzira kukurumidza kwehupfumi hwenyika, kunyanya kutsigirwa kwemitemo yenyika, kugadzirwa uye kushandiswa kwepombi yePVC kwaita budiriro huru, kugadzirwa kwepombi yePVC kwakaverengera kupfuura 50% yakazara kuburitsa pombi dzepurasitiki, dzinoshandiswa zvakanyanya muindasitiri, kuvaka, kurima uye mamwe maindasitiri mazhinji.Nekuda kwekukurumidza kusimudzira kwePVC mapaipi muChina, kudiwa kwePVC maitiro ekugadzirisa kwakawedzerawo.Chigadzirwa chedu ADX-600 kukanganisa ACR yakaomeswa PVC pombi ine yakanakisa mechaniki zvivakwa.Iyo pombi yekupa mvura ine zvakanakira hutano, kuchengetedzwa, kusimba, kuchengetedza simba, kuchengetedza kwezvakatipoteredza uye hupfumi, etc. Iine huwandu hwakawanda hwekushandisa, kunyanya kusanganisira pasi pevhu pombi network yekugovera mvura, kugovera mvura masisitimu muzvivako zvehurumende uye zvemabhizimisi. , zvekurapa, makemikari uye zvinwiwa indasitiri yekuendesa masisitimu, nzvimbo dzeveruzhinji uye masisitimu ekudiridza mubindu, nezvimwe.
I. Nhanganyaya yeADX-600 inokanganisa ACR zvigadzirwa
Property
ADX-600 impact modifier ihupfu inoyerera yakasununguka.
| Property | Index | Unit |
| Chimiro | Upfu chena | |
| Bulk density | 0.4-0.6 | g/cm³ |
| Volatile | ＜1.0 | % |
| 20 mesh kuongorora | ＞99 | % |
*Indekisi inongomiririra mhedzisiro isingatariswe seyakatsanangurwa.
Hunhu Hunokosha
●Good impact simba
●Kuramba kwakavimbika kwemamiriro okunze
● Kuvandudza plasticizing kunyatsoshanda
● Yakaderera post-extrusion shrinkage kana kutendeuka
● Yakanakisa kugadzirisa zvinhu uye yakakwirira gloss
Rheology uye Kubata
ADX-600 impact modifier inoratidza kukurumidza fusion hunhu pane zvigadzirwa zvinokwikwidza, izvo zvinobvumira mabhenefiti ehupfumi nekudzikisira mazinga emuyero wezvishandiso zvekugadzirisa uye mafuta emukati mukugadzira.
Impact simba
ADX-600 mhedzisiro inogadzirisa inopa yakanaka maitiro ekuvandudza pakamuri tembiricha uye 0°C.
Kubudirira kweADX-600 kwakanyanya kudarika zvigadzirwa zvemakwikwi.
II.Kuenzanisa kwekuita kweADX-600 kukanganisa kusagadzikana ACR ine akasiyana modifiers
Chigadzirwa chedu ADX-600 kukanganisa ACR ndeye-core-shell acrylate impact modifier yakagadzirwa neemulsion polymerization.Zvinoratidzwa kuti zvikamu zvitatu zveADX-600 + 3 phr CPE zvinogona kushandiswa panzvimbo ye9 phr CPE muPVC mapaipi;ADX-600 inogona kushandiswa muzvikamu zvakaenzana panzvimbo yeMBS.Mukupedzisa, ADX-600 kukanganisa ACR ine zvirinani kuita kwese uye izvo zvinogadzirwa zvine zvirinani zvemakanika zvivakwa uye zvinodhura-zvinoshanda.Izvi zvinotevera kuongororwa kwekuenzanisa kwekuita kweakasiyana maitiro ekugadzirisa mumhando dzakasiyana dzepombi.
