POLYURETHANE muag ua npuas ncauj yog dav siv nyob rau hauv rooj tog, automotive sab hauv thiab lwm daim teb. Nws ntau lawm tsim kev sib xyaw ntawm cov ntaub ntawv nyoos xws li polyols, Isocyanates thiab ntxiv. Cov khoom sib xyaw ua ke yog cov khoom siv raw ua ntej ua ntej, thaum cov khoom siv uas yuav tsum tau npaj los ntawm tus neeg siv. Ob qho tib si muaj lawv tus kheej zoo thiab qhov tsis zoo nyob hauv daim ntawv thov.
Qhov zoo ntawm cov khoom sib xyaw ua ke:
1. Cov txheej txheem yooj yim thiab kev txhim kho ua ke tau ua ntej los ntawm cov neeg siv khoom, muaj peev xwm txo cov khoom sib xyaw ua ntej, tshwj xeeb yog tsim nyog rau cov khoom lag luam me me thiab nruab nrab nrog cov khoom siv hluav taws xob tsis muaj zog.
2. Lub zog ua tau zoo ruaj khov: Tus neeg muag khoom kom ua rau cov kev pheej hmoo tsim thiab homogenization kev pheej hmoo, txo qhov kev pheej hmoo ntawm cov khoom tsis xws luag los ntawm kev sib piv.
3. Cov txheej txheem kev txhawb nqa zoo tshaj: Cov chaw muab khoom feem ntau muab cov txheej txheem kev txhawb nqa (xws li kub thiab cuam tshuam cov neeg siv khoom R & D txo tus nqi thiab ua yuam kev.
4. Kev tswj hwm yooj yim: tsuas yog ib qho khoom siv sib xyaw ua ke yuav tsum tau khaws cia, txo cov khoom ntim thiab muaj kev pheej hmoo ntawm cov khoom siv raw.
Qhov tsis zoo ntawm cov khoom sib xyaw ua ke:
1. Tus nqi siab: Kev pabcuam ua haujlwm thiab thev naus laus zis ntawm tus nqi sib xyaw ua ke, thiab siv tau ntev dua qhov kev yuav tus kheej, thiab kev siv ntev ntev ntxiv.
2. Kev siv tau yooj yim ntawm cov qauv: Cov neeg siv tsis tuaj yeem hloov kho cov feem ntawm cov khoom sib xyaw ua ke, xws li nplaim taws kev txhim kho rov ua dua tshiab), thiab cia siab rau cov neeg xa khoom rau kev txhim kho.
3. Cov khoom siv sib xyaw ua ke: Qhov cuam tshuam ntawm kev muab cov khoom siv ntawm cov khoom siv ntawm cov khoom siv tag nrho, thiab kev tsis pub lwm tus paub ntawm cov neeg siv khoom muaj peev xwm.
Qhov zoo ntawm cov khoom siv cais:
1. Tseem ceeb tus nqi tswj: kev yuav cov khoom siv raw khoom plig tuaj yeem txo cov nqi ntawm cov nqi, thiab cov lag luam tsim khoom loj tuaj yeem txuag cov nqi los ntawm ntau dua 15%.
2. Cov mis ywj pheej ywj pheej
3. Txhim kho cov khoom siv hluav taws xob rov qab: ntau txoj kev thauj khoom cuam tshuam kev pheej hmoo, zam kev txwv tsis pub los ntawm ib tus neeg xa khoom siv yog hloov tau yooj yim.
Qhov tsis zoo ntawm cov khoom siv:
1. Cov cuab yeej siv R & D & D D & DE (xws li visteter, thiab cov lag luam me me thiab nruab nrab tsis tuaj yeem them taus cov peev txheej pib.
2.
3. Cov nqi tswj kev tswj hwm nce: ib qho khoom siv raw kev phom sij yuav tsum tau tsim cov kev phom sij tswj cov cai, nce nqi kev ua haujlwm.
Hauv cov ntsiab lus, kev sib xyaw ua ke yog qhov tsim nyog rau cov qauv tsim khoom thiab cov khoom lag luam muaj zog ntau rau cov kev sib tw ua haujlwm nrog kev sib tw. Kev lag luam yuav tsum ua cov kev xaiv raws lawv tus kheej nplai, kev lag luam thiab khoom tso tawm. Qee cov tuam txhab tsim khoom txais yuav cov khoom sib xyaw ua ke "cov ntaub ntawv sib xyaw ua ke Nyob rau yav tom ntej, nrog rau kev txhim kho cov tshuab ntse ntse, qhov pib rau kev siv cov khoom siv ib leeg tau txo qis, tsav tsheb mus hloov zuj zus mus rau kev tsim khoom.
