Phenolic resin pazinthu zoyambira
Phenolic resin kwa maziko
Mndandandawu ndi thermoplastic phenolic resin yokhala ndi ma flakes achikasu kapena ma granular, omwe amadziwika motere:
1. Utomoni uli ndi mphamvu zambiri ndipo kuchuluka kwa kuonjezera kumakhala kochepa, komwe kungachepetse mtengo.
2. Kutsika kwa gasi, kuchepetsa kuponyera zolakwika za porosity ndikuwonjezera zokolola.
3. Utoto umakhala ndi kuyenda bwino, kujambula kosavuta, ndikudzaza popanda ngodya yakufa.
4. Phenol yaulere yotsika, imachepetsa kuwononga chilengedwe komanso kukonza malo ogwira ntchito a ogwira ntchito.
5. Liwiro lofulumira, sinthani kuwombera bwino ndikuchepetsa maola ogwirira ntchito.

Kulongedza ndi kusunga
Phukusi: flake / granular: 25kg/40 kg pa thumba, Onyamula mu thumba nsalu, kapena Kraft pepala thumba ndi pulasitiki liner mkati. Utoto uyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino kutali ndi kutentha
Kugwiritsa ntchito
Phenolic resin wapadera kwa mchenga wokutidwa ndi maziko, womwe umagwiritsidwa ntchito ngati maziko olimba ndi chipolopolo popanga mchenga wokutidwa. Lili ndi makhalidwe amphamvu kwambiri komanso otsika otsika a phenol
Malangizo
3.1 Kusankha mchenga. Mukamagwiritsa ntchito, choyamba sankhani kukula kwa mchenga waiwisi malinga ndi zofunikira.
3.2 Mchenga wokazinga. Pambuyo kusankha tinthu kukula, kulemera wina yaiwisi mchenga kwa Frying.
3.3 Onjezani phenolic resin. Pambuyo kutentha kufika 130-150 ℃, kuwonjezera phenolic utomoni.
3.4 Gauto madzi yankho. Kuchuluka kwa Utopia wowonjezera ndi 12-20% ya kuwonjezera kwa utomoni.
3.5 Onjezani calcium stearate.
3.6 Kuchotsa mchenga, kuphwanya, kuyesa, kuziziritsa, ndi kusunga.
4. Nkhani zofunika kuziganizira:
Utoto uyenera kusungidwa pamalo opumira mpweya komanso owuma. Pewani kuwala kwa dzuwa komanso kupewa kutentha. Kutentha kosungirako sikuyenera kupitirira 35°C. Osaunjika thumba la utomoni pamwamba kwambiri pakusunga. Mangani pakamwa mwamsanga mukangogwiritsa ntchito kuti musamangirire.
