1. Cov particle loj thiab hardness ntawm lubresinoid sib tsoo logcov khoom tsis sib xws.
Txoj kev: nruj me ntsis xam cov khoom xyaw raws li cov khoom muaj npe thiab tshuaj xyuas cov txheej txheem tseem ceeb;
2. Cov kab nrib pleb hauv cov molded dawb paug. Qhov kub nias kub yog siab dhau lawm, cov resinoid sib tsoo log yog txias thiab rhuab sai, qhov kub thiab txias yog tsawg heev thaum lub tub ntxhais raug tshem tawm, lub tub ntxhais yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm, cov ntaub ntawv raw yog damp thiab deteriorated, los yog cov ntaub ntawv sib xyaw. yuam kev;
ib. Xaus ntsej muag tawg. Lub plasticity ntawm cov khoom molding yog qhov tsis zoo, thiab cov txheej txheem ntawm kev tshem tawm cov pwm yog qhov tsis tsim nyog. Lub phaj hauv qab ntawm cov pwm molding tsis sib npaug los yog qhov sib npaug ntawm lub ncoo loj dhau.
b. Peripheral tawg. Lub tes tsho pwm yog hnav hnyav heev, thiab lub tes tsho pwm yog tilted heev thaum unloading.
c. Aperture tawg. Lub zog tsis muaj zog yog qhov tsawg, qhov kev vibration loj dhau thaum lub sijhawm thauj khoom, cov tub ntxhais pas nrig hnav dhau los lossis lub taper me dhau, thiab cov khoom thauj tsis tau raws li cov kev qhia tshwj xeeb.
d. Kab pheeb ces kaum. Lub caij nplooj ntoos hlav pad hlau siv muaj qhov tsis sib xws elasticity, uas ua rau cov pwm yuav qaij thiab compressed los tsim kab kab pheeb ces kaum. Cov khoom zoo pwm ceev ceev heev, lub siab yog khaws cia rau ib lub sij hawm luv luv, thiab pwm kev koom tes sib txawv loj heev.
e. Kev tiv thaiv cov kab nrib pleb ntawm cov pob zeb sib tsoo: kho cov yas ntawm cov khoom sib xyaw, cov molding tuag yuav tsum tsis txhob tshaj cov txheej txheem hnav, cov qauv thiab cov shim yuav tsum tuav zoo flatness, thickness ntawm shim yuav tsum zoo ib yam, elasticity ntawm lub caij nplooj ntoos hlav. shim yuav tsum zoo ib yam, thiab cov pwm yuav tsum tau unloaded raws li cov kev cai;
3. Sib tov. Ua ntej thiab thaum sib tov, ntxuav cov cuab yeej. Ua ntej batch, xyuas seb cov khoom siv puas muaj impurities;
4. Kev sib xyaw tsis sib xws. Sib tov raws li lub sijhawm sib xyaw uas xav tau los ntawm kev siv tshuab. Hloov cov khoom sib tov uas hnav dhau lawm txhua lub sijhawm. Cov khoom siv hmoov nplej yuav tsum tau sieved raws li tus lej mesh thiab zaus tau teev tseg hauv cov kev cai;
5. Lub hardness molding tsis ua raws li qhov yuav tsum tau ua. Thawj daim yuav tsum raug kuaj xyuas, thiab tsis pub tsawg dua 30% ntawm cov khoom seem hauv txhua pawg yuav tsum tau kuaj. Tshawb xyuas qhov ntsuas qhov hnyav ntau zaus thiab saib seb lub siab hloov nquag;
6. Tus choj tsis sib haum. Cov cua txias yuav tsum tsis sib xws; lub "warping" ntawm qhov chaw ntawm lub workpiece tsis muaj lub tiaj tiaj yog hu ua choj. Qhov no yog tshwm sim los ntawm qhov txias txias tsis sib xws, uas ua rau lub tshuab ua haujlwm tsis sib xws lossis cov ntaub qhwv tsis sib xws rau kev thauj khoom rau lub qhov cub. Nws yog feem ntau tshwm sim los ntawm nyias-zaj duab xis sib tsoo log thiab nplua-grained nyias cov khoom. Nyias-zaj duab xis sib tsoo lub log yog qhov ua rau tus choj tsis xws luag thaum lub cua txias nrawm dhau;
7. Kev npaj tsis sib xws thiab tsis sib xws. Kho cov dryness thiab humidity ntawm qhov sib tov kom nws muaj moldability zoo. Ua cov khoom sib kis thiab khawb cov haujlwm raws li kev xav tau. Siv cov ntaub qhwv ua ntej raws li kev xav tau los tswj qhov tseeb ntawm cov xovxwm; Thaum pub mis, cov khoom sib kis thiab khawb tsis sib xws, cov khoom sib xyaw yog ntub heev, los yog cov khoom yog agglomerated, pub mis tsis sib npaug, pwm hnav, thiab cov xau loj heev, thiab cov pwm yuav tsum tau hloov;
8. Ob qhov kawg ntawm qhov chaw tsis sib luag. Tswj xyuas qhov tseeb ntawm cov xovxwm txwv lub rooj thiab ua haujlwm raws li kev cai;
9. Qhov saum npoo tsis sib xws. Cov cuab yeej cuab tam raug tswj xyuas nyob rau hauv qhov yuav tsum tau muaj qhov tseeb;
10. Ua npaws. Tswj cov kub hardening raws li lub hardening nkhaus ntawm lub resinoid sib tsoo log txheem, thiab nruj me ntsis tswj qhov zoo ntawm cov txheej txheem sib tov; molding kub yog siab dhau los yog tsawg dhau, thiab qhov kub thiab txias yuav tsum tau hloov kho. Lub curing kub yog siab dhau lawm, thiab qhov kub ntawm qhov cub curing yog tsis tswj. Lub binder tsis ncaj ncees lawm; Qhov saum npoo ntawm qhov superhard abrasive yog convex thiab deformed los yog tag nrho cov nto yog o, thiab nws muaj ib tug resin luster, thiab ib co muaj vaub kib-zoo li tus kab nrib pleb.
Ua rau:
ib. Cov cua kub ceev dhau los yog qhov kub thiab txias hloov tau yooj yim, uas yooj yim ua rau cov nplua-grained, high-hardness, thiab nruj nreem kaw qhov chaw ua npuas thiab o. Vim hais tias resinoid sib tsoo log muaj ntau ntawm cov binder los yog me me pores, yog hais tias qhov kub thiab txias tsis yog qhov tseeb thiab cov cua kub ceev ceev heev, nws yuav ua rau lub binder muaj zog heev, tus nqi ntawm cov volatiles yuav nce sharply, thiab cov roj sab hauv. lub siab ntawm qhov khoob yuav siab, ua rau cov khoom ua npuas thiab o.
b. Cov khoom siv molding tsis sib tov sib npaug, muaj cov ntaub qhwv hauv cov khoom lossis nws muaj cov kuab tshuaj uas muaj cov ntsiab lus qis dua (xws li ethanol, acetone).
c. Ua los ntawm kev ua yuam kev hauv kev sib xyaw thiab molding txheej txheem, tus nqi ntawm cov binder nyob rau hauv ib feem yog nce, chav tsev qhov hnyav yog nce, thiab lub siab yog nce.
