Phenolic resin yezvinhu zvekuvakisa
Phenolic resin for foundry
Iyi nhevedzano ndeye thermoplastic phenolic resin ine yero flakes kana granular, inoratidzwa nenzira inotevera:
1. Iyo resin ine simba guru uye huwandu hwekuwedzera hudiki, hunogona kuderedza mari.
2. Kudzika gasi chizvarwa, kuderedza kukanda porosity kukanganisa uye kunatsiridza goho.
3. Resin ine kuyerera kwakanaka, nyore kutora mafirimu, uye kuzadza pasina chero kona yakafa.
4. Low free phenol, kuderedza kusvibiswa kwezvakatipoteredza uye kugadzirisa nzvimbo yekushanda yevashandi.
5. Kukurumidza kukurumidza, kuvandudza kupfura kwepakati uye kuderedza maawa ekushanda.

Kurongedza uye kuchengetedza
Package: flake/granular: 25kg/40 kg per bag, Yakarongedzwa mubhegi rakarukwa, kana muKraft paper bag ine plastic liner mukati. Resin inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye yakanaka inofefetera kure nekupisa
Application
Phenolic resin yakakosha kune yakavharwa jecha, inonyanya kushandiswa kune yakasimba musimboti uye goko mukugadzirwa kwejecha rakavharwa. Iine maitiro ehusimba hwepamusoro uye yakaderera yemahara phenol content
Mirayiridzo
3.1 Sarudzo yejecha. Paunenge uchishandisa, tanga wasarudza saizi yejecha mbishi maererano nezvinodiwa.
3.2 Jecha rakakangwa. Mushure mekusarudza saizi yechidimbu, yera huremu hwakati hwejecha mbishi yekukacha.
3.3 Wedzera phenolic resin. Mushure mekunge tembiricha yasvika 130-150 ℃, wedzera phenolic resin.
3.4 Gauto mvura mhinduro. Huwandu hweUtopia hwakawedzerwa ndeye 12-20% yekuwedzera resin.
3.5 Wedzera calcium stearate.
3.6 Kubvisa jecha, kupwanya, kuongorora, kutonhodza, nekuchengetedza.
4. Nyaya dzinoda kutariswa:
Resin inofanira kuchengetwa munzvimbo ine mhepo uye yakaoma. Dzivisa chiedza chezuva uye chengeta kure nezvinopisa. Tembiricha yekuchengetera haifanirwe kudarika 35°C. Usaisa bhegi resin zvakanyanyisa panguva yekuchengetedza. Sunga muromo pakarepo mushure mekushandisa kuti udzivise agglomeration.
