I-phenolic resin yezinto zokwakha
Phenolic resin for foundry
Lolu chungechunge luyi-thermoplastic phenolic resin enama-flakes aphuzi noma ama-granulars, abonakala ngale ndlela elandelayo:
1. I-resin inamandla amakhulu futhi inani lokwengeza lincane, elinganciphisa izindleko.
2. Ukukhiqizwa kwegesi okuphansi, ukunciphisa ukukhubazeka kwe-porosity futhi kuthuthukise isivuno.
3. I-resin inokugeleza okuhle, ukuqoshwa okulula, nokugcwalisa ngaphandle kwe-engeli efile.
4. I-phenol yamahhala ephansi, inciphisa ukungcoliswa kwemvelo futhi ithuthukise indawo yokusebenza yabasebenzi.
5. Isivinini esisheshayo, sithuthukise ukusebenza kahle kokudubula okuyisisekelo futhi sinciphise amahora okusebenza.

Ukupakisha nokugcina
Iphakheji: i-flake / granular: 25kg / 40 kg isikhwama ngasinye, Ipakishwe esikhwameni esilukiweyo, noma esikhwameni sephepha se-Kraft esine-plastic liner ngaphakathi. I-resin kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle kude nokushisa
Isicelo
I-Phenolic resin ikhethekile yesihlabathi esimbozwe ngesisekelo, esisetshenziselwa ikakhulukazi umgogodla oqinile kanye negobolondo ekukhiqizeni isihlabathi esimboziwe. Inezici zamandla aphezulu kanye nokuqukethwe okuphansi kwe-phenol yamahhala
Iziyalezo
3.1 Ukukhetha kwesihlabathi. Uma usebenzisa, khetha kuqala usayizi wezinhlayiyana zesihlabathi esingavuthiwe ngokwezidingo.
3.2 Isihlabathi esithosiwe. Ngemva kokukhetha usayizi wezinhlayiyana, kala isisindo esithile sesihlabathi esiluhlaza sokuthosa.
3.3 Faka i-phenolic resin. Ngemuva kokuthi izinga lokushisa lifinyelele ku-130-150 ℃, engeza i-phenolic resin.
3.4 Isixazululo samanzi eGauto. Inani le-Utopia elingeziwe liyi-12-20% yokwengezwa kwe-resin.
3.5 Faka i-calcium stearate.
3.6 Ukukhipha isihlabathi, ukuchotshozwa, ukuhluza, ukupholisa, nokugcina.
4. Izindaba ezidinga ukunakwa:
I-resin kufanele igcinwe endaweni engenawo umoya futhi eyomile. Gwema ukukhanya kwelanga okuqondile futhi uqhelelane nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-35°C. Ungasitaki isikhwama se-resin sibe phezulu kakhulu ngesikhathi sokugcina. Bopha umlomo ngokushesha ngemva kokusetshenziswa ukuze ugweme i-agglomeration.
