I-phenolic resin yezinto ezisisiseko
Phenolic resin for foundry
Olu luhlu luyi-resin ye-phenolic ye-thermoplastic eneflakes ezityheli okanye iigranulars, eziphawulwe ngolu hlobo lulandelayo:
1. I-resin inamandla amakhulu kwaye inani lokongezwa lincinci, elinokunciphisa iindleko.
2. Ukuveliswa kwegesi ephantsi, ukunciphisa ukuphosa iziphene ze-porosity kunye nokuphucula isivuno.
3. I-resin inokuhamba kakuhle, ukufota ngokulula, kunye nokuzaliswa ngaphandle kwe-engile efileyo.
4. I-phenol ephantsi yamahhala, ukunciphisa ukungcoliseka kwendalo kunye nokuphucula indawo yokusebenza yabasebenzi.
5. Ukukhawuleza ngokukhawuleza, ukuphucula ukusebenza kakuhle kokudubula kunye nokunciphisa iiyure zokusebenza.

Ukupakisha kunye nokugcinwa
Iphakheji: i-flake / granular: 25kg / 40 kg isikhwama ngasinye, Ipakishwe kwisikhwama esilukiweyo, okanye kwisikhwama sephepha seKraft esineplastiki ngaphakathi. Intlaka yentlaka kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye nengena umoya kakuhle kude nobushushu
Isicelo
I-phenolic resin ekhethekileyo yesanti egqunywe ngesiseko, isetyenziswa ikakhulu kumbindi oqinileyo kunye neqokobhe ekuvelisweni kwesanti egqunyiweyo. Ineempawu zamandla aphezulu kunye nomxholo ophantsi we-phenol wamahhala
Imiyalelo
3.1 Ukukhetha isanti. Xa usebenzisa, khetha kuqala ubungakanani besuntswana lesanti ekrwada ngokweemfuno.
3.2 Isanti eyojiweyo. Emva kokukhetha ubungakanani bamasuntswana, linganisa ubunzima obuthile besanti ekrwada yokuqhotsa.
3.3 Yongeza i-phenolic resin. Emva kokuba ubushushu bufikelele kwi-130-150 ℃, yongeza i-phenolic resin.
3.4 Unyibiliko lwamanzi eGauto. Isixa se-Utopia esongeziweyo yi-12-20% yokongeza i-resin.
3.5 Yongeza i-calcium stearate.
3.6 Yenza ukususwa kwesanti, ukuyityumza, ukuhluza, ukupholisa, kunye nokugcinwa.
4. Imiba efuna ukuqwalaselwa:
I-resin kufuneka igcinwe kwindawo engenamoya kunye neyomileyo. Kuphephe ukukhanya kwelanga kwaye uzigcine kude nemithombo yobushushu. Ubushushu bokugcina akufunekanga budlule kuma-35°C. Musa ukupakisha ingxowa ye-resin phezulu kakhulu ngexesha lokugcinwa. Bopha umlomo ngoko nangoko emva kokusetyenziswa ukunqanda i-agglomeration.
