Phenolic resin rau cov khoom tsim
Phenolic resin rau qhov chaw tsim khoom
Cov koob no yog thermoplastic phenolic resin nrog daj flakes los yog grannulars, yam ntxwv hauv qab no:
1. Cov resin muaj lub zog siab thiab qhov sib ntxiv yog me me, uas tuaj yeem txo tus nqi.
2. Tsawg roj tsim, txo cov casting porosity tsis xws luag thiab txhim kho yield.
3. Cov resin muaj zoo flowability, yooj yim filming, thiab filling tsis muaj lub kaum sab xis tuag.
4. Tsis tshua muaj phenol dawb, txo cov pa phem ib puag ncig thiab txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm.
5. Fastening ceev, txhim kho cov tub ntxhais shooting efficiency thiab txo cov sij hawm ua hauj lwm.

Ntim thiab khaws cia
Pob: flake / granular: 25kg / 40 kg ib lub hnab, Ntim rau hauv lub hnab woven, los yog hauv Kraft daim ntawv hnab nrog yas liner hauv. Resin yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo ventilated qhov chaw deb ntawm tshav kub
Daim ntawv thov
Phenolic resin tshwj xeeb rau foundry coated xuab zeb, feem ntau yog siv rau cov tub ntxhais thiab plhaub hauv kev tsim cov xuab zeb coated. Nws muaj cov yam ntxwv ntawm lub zog siab thiab tsis muaj cov ntsiab lus phenol dawb
Cov lus qhia
3.1 Xuab zeb xaiv. Thaum siv, thawj zaug xaiv qhov loj me ntawm cov xuab zeb nyoos raws li qhov yuav tsum tau ua.
3.2 Fried xuab zeb. Tom qab xaiv qhov loj me me, hnyav ib qho hnyav ntawm cov xuab zeb nyoos rau kib.
3.3 Ntxiv phenolic resin. Tom qab qhov kub nce mus txog 130-150 ℃, ntxiv phenolic resin.
3.4 Gauto dej tov. Tus nqi ntawm Utopia ntxiv yog 12-20% ntawm cov resin ntxiv.
3.5 Ntxiv calcium stearate.
3.6 Ua cov xuab zeb tshem tawm, crushing, tshuaj ntsuam xyuas, txias, thiab cia.
4. Cov teeb meem xav tau kev saib xyuas:
Cov resin yuav tsum tau muab cia rau hauv qhov chaw ventilated thiab qhuav. Tsis txhob tshav ntuj ncaj qha thiab kom deb ntawm qhov chaw sov. Qhov kub cia yuav tsum tsis pub tshaj 35 ° C. Tsis txhob tso lub hnab resin siab dhau thaum khaws cia. khi lub qhov ncauj tam sim ntawd tom qab siv kom tsis txhob agglomeration.
