Pulogalamu ya propyl iyenera kusungidwa bwino kuti zitsimikizire chitetezo chake ndikusungabe. Nawa maupangiri ena osungira ma propyl acetate:
1. Zovala: Sungani Propyl Acetate m'matumbo opangidwa ndi zida zogwirizana monga galasi kapena pulasitiki ina. Onetsetsani kuti chidebe chimalembedwa.
2.
3. Kutentha: Sungani pansi pa 25 ° C (77 ° F) kuteteza kuwonongeka kapena kukakamizidwa mu chidebe.
4. Pewani dzuwa: pewani dzuwa ndi kuwala kwa dzuwa ndi kuwopa kwa ultraviolet popeza izi kungakhudze kukhazikika kwa mankhwala.
5. Kusagwirizana: Pewani kwa oxidants amphamvu, ma asidi ndi zitsulo monga angachitire ndi ma propyl acetate.
6. Kusamala kwa chitetezo: Onetsetsani kuti malo osungirako ali ndi zida zoyenera zotetezeka, monga zozimitsa moto ndi zozimitsa moto.
Pulogalamu ya proyl imatha kukhala yovulaza anthu ngati sinagwiritsidwe ntchito bwino. Nazi mfundo zazikuluzikulu zokhudzana ndi zotsatira zake:
1. Kupumira: Kuwonetsedwa kwa Proyl Acetate Vapor kungapangitse kupuma, chizungulire, kupweteka mutu komanso nseru. Kuwonekera kwapamwamba kapena kwakukulu kungayambitse mavuto ena opumira.
2. Kulumikizana ndi khungu: Kulumikizana kungapangitse khungu kapena khungu. Kulumikizana kwa nthawi yayitali kungayambitse khungu lalikulu kwambiri.
3. Lumikizanani ndi maso: Aceyl acetate amatha kuyambitsa kuchepa kwa maso, kuwononga ndi kusapeza bwino.
4. Kulowetsa: Kumetsa kwa propyl kumatha kukhala koopsa ndipo kungayambitse kupsinjika, nseru, kusanza, ndi thanzi lina lalikulu.
5.
Mukamaika ma propyl acetate, ndikofunikira kutsatira mosamala mosamala kuti mutsimikizire kuti mwachita chitetezo ndi kutsatira. Nayi malingaliro akuluakulu omwe mungaganizire:
1. Kutsatira lamulo: Onetsetsani kutsatira malamulo am'deralo, mayiko ndi mayiko okhudza mayendedwe owopsa. Pulogalamu ya propyl imasungidwa ngati madzi oyaka ndipo chifukwa chake iyenera kunyamulidwa pansi pa chitsogozo choyenera (mwachitsanzo, 1279).
2. Ma Cantrating: Gwiritsani ntchito zotengera zoyenera zopangidwa kuti zizinyamula zakumwa zoyaka. Zotengera ziyenera kusindikizidwa mwamphamvu ndikupangidwa ndi zida zophatikizika (monga galasi kapena mapulasitiki ena). Onetsetsani kuti phukusi limakhala lamphamvu kuti lithe kupirira ndi zotumizira.
3. Kulemba: lembani zowonekera bwino ndi dzina lolondola lotumizira, osagwirizana ndi chizindikiro chowopsa. Phatikizani malangizo aliwonse ogwiritsira ntchito mankhwala otetezeka.
4. Kuwongolera kutentha: Pewani kuvumbula propyl acetate ku kutentha kwambiri pakuyendera. Iyenera kusungidwa pamalo ozizira komanso okhazikika popewa kuthamanga ndi kutayikira.
5. Pewani kusakaniza: Musamayendetse ma propyl artate palimodzi ndi zida zosagwirizana monga oxidizer, ma acid, kapena zitsulo kuti mupewe mavuto.
6. Njira zadzidzidzi: khalani njira yankho ladzidzidzi ladzidzidzi lazolowera kapena kutayikira nthawi paulendo. Onetsetsani kuti ogwira ntchito poyenda pamayendedwe amaphunzitsidwa kuti azigwira zida zowopsa.
7. Zolemba: Konzekerani ndi kuphatikiza zikalata zonse zofunika kutumiza, monga ndalama zam'manja ndi ma stati otetezedwa (sds) kuti mupereke chidziwitso pazomwe zidatumizidwa.
