Yuav khaws cia li caspolyether polyols?
Cov thawv rau polyether polyols tuaj yeem ua los ntawm cov hlau, txhuas, polyethylene lossis polypropylene.
Qhov kub cia yuav tsum tsis pub tshaj 70 degree.
Txhawm rau tiv thaiv kev nqus dej thiab oxidation, nws raug nquahu kom lub thawv ntim nrog nitrogen. Tsis yog raws li txoj cai cia rau cov kua dej uas muaj nplaim taws, tab sis yuav tsum tsis txhob nkag mus rau hauv av los yog dej saum npoo av vim nws tsis yooj yim biodegradable.
Feem ntau, cov toxicity ntawm nruab nrab polyether polyols thaum noj rau hauv lub qhov ncauj los yog nyob rau hauv kev sib cuag nrog daim tawv nqaij, qhov muag, los yog mucous daim nyias nyias yog negligible, yog li kev tiv thaiv tus kheej yog tsis tsim nyog thaum siv.
Amino polyether polyols tuaj yeem ua rau tawv nqaij thiab qhov muag vim lawv cov alkalinity, yog li tsom iav kev nyab xeeb, hnab looj tes thiab lwm yam khoom siv tiv thaiv yuav tsum tau hnav thaum ua haujlwm.
Kev khaws cia ntawm polyether polyols yog qhov tseem ceeb los tswj lawv qhov zoo thiab tiv thaiv kev degradation dhau sijhawm. Nov yog qee cov lus qhia rau kev khaws cia kom zoo:
1. Kev tswj qhov kub thiab txias:
- Khaws polyether polyols hauv qhov chaw txias thiab qhuav.
- Tsis txhob raug rau qhov kub thiab txias, vim tias ob qho tib si kub thiab txias txias tuaj yeem cuam tshuam tsis zoo rau polyol qhov kev ruaj ntseg thiab kev ua haujlwm.
2. Qhov cua:
- Ua kom muaj qhov cua zoo hauv qhov chaw cia kom tiv thaiv kom tsis txhob muaj vapors.
- Khaws polyether polyols kom deb ntawm tshav ntuj ncaj qha thiab qhov chaw tshav kub.
3. Thawv tuav:
- Siv cov thawv ua los ntawm cov khoom sib xws nrog polyether polyols, xws li stainless hlau lossis high-density polyethylene (HDPE).
- Khaws cov thawv ntim kom nruj kom tiv thaiv kom tsis txhob ya raws thiab kis kab mob.
- Txo lub taub hau hauv cov thawv kom txo tau qhov kev pheej hmoo ntawm oxidation.
4. Zam kev kis kab mob:
- Tiv thaiv kom tsis txhob muaj dej noo, huab cua, thiab cov kab mob sib kis los ntawm kev siv cov cuab yeej tshwj xeeb rau kev hloov thiab tuav cov polyether polyols.
- Siv cov cuab yeej huv, qhuav thaum lub sijhawm hloov pauv.
5. Inert Gas Blanketing:
- Xav txog kev siv cov pa roj inert (xws li nitrogen) daim pam kom tshem tawm cov huab cua hauv cov thawv ntim khoom, txo qhov kev pheej hmoo ntawm oxidation.
6. Cia Lub Sijhawm:
- Ua raws li kev pom zoo lub neej txee muab los ntawm cov chaw tsim khoom.
- Siv cov khoom ua ntej-hauv, ua ntej-tawm (FIFO) cov khoom lag luam kom ntseeg tau tias cov khoom qub siv ua ntej cov khoom tshiab.
7. Cov txheej txheem tuav:
- Tsis txhob cuam tshuam rau huab cua thaum tuav thiab hloov pauv.
- Siv cov twj tso kua mis tsim nyog thiab cov hoses kom txo qis kev sib cuag nrog cua.
8. Kev soj ntsuam thiab kuaj:
- Txheeb xyuas qhov xwm txheej ntawm cov polyether polyols khaws cia.
- Ua qhov kev sim niaj hnub rau cov khoom tseem ceeb, xws li tus lej hydroxyl thiab viscosity, kom ntseeg tau tias lawv ua tau raws li cov lus qhia tshwj xeeb.
9. Kev ntsuas kev nyab xeeb:
- Ua raws li cov lus qhia txog kev nyab xeeb thiab cov cai tswj xyuas thiab khaws cov tshuaj.
- Khaws cov chaw cia kom muaj teeb pom kev zoo thiab nruab nrog cov khoom siv thaum muaj xwm ceev.
