Isitolo
Ubufakazi bomlilo namanzi
Ukusetshenziswa
Isetshenziselwa ukukhiqiza ama-phenolic resins ancibilikayo kawoyela, ama-stabilizer alula namaphunga.
Impahla yamakhemikhali
[Ukusabela kwamakhemikhali okujwayelekile] ngokushintshwa kwendandatho ye-phenol-benzene kanye nezici zokusabela ze-hydroxyl.
I-oxidant
[Ingozi yokwenza i-Polymerization] Ayikho ingozi yokwenza i-polymerization
Ukusetshenziswa Main
I-P-tert-butylphenol ine-antioxidant futhi ingasetshenziswa njengesiqinisi serabha, insipho, ama-hydrocarbon ane-chlorinated kanye nemicu yokugaya ukudla.Ukumunca i-Uv, isibulala-zinambuzane, irabha, upende nokunye okunqanda ukuqhekeka.Isibonelo, isetshenziselwa i-polycarbon resin, i-tert-butyl phenolic resin, i-epoxy resin, i-polyvinyl chloride, i-styrene stabilizer.Ngaphezu kwalokho, kuphinde kube yimpahla eluhlaza yesibulala-zinambuzane ezenza imithi, isibulala-zinambuzane kanye ne-acaricide, iphunga elimnandi ne-ejenti yokuvikela izitshalo.Ingasetshenziswa futhi njengesithambisi, isincibilikisi, isithasiselo sikadayi nopende, i-antioxidant yamafutha okugcoba, i-demulsifier kawoyela kanye nesengezo samafutha emoto.
Ubuthi kanye nemvelo
Lo mkhiqizo ungowobuthi bamakhemikhali.Ukuhogela umoya, ukuthintana nekhala, amehlo noma ukumunca kungacasula amehlo, isikhumba nolwelwesi lwamafinyila.Ukuthintana kwesikhumba kungabangela i-dermatitis kanye nobungozi bokusha.Ukubola kokushisa kukhipha igesi enobuthi;
Lo mkhiqizo unobuthi ezintweni eziphila emanzini futhi ungase ube nemiphumela emibi yesikhathi eside endaweni yasemanzini.Naka izingozi zemvelo zemfucuza kanye nemikhiqizo evela ohlelweni lokukhiqiza.
Ukupakisha, ukugcinwa kanye nokuthutha
Umkhiqizo ufakwe ifilimu ye-polypropylene, ehlanganiswe nesikhwama sephepha esingazweli ukukhanya futhi sipakishwe ebhakedeni lekhadibhodi eliqinile elinesisindo senethi esingu-25Kg/ isikhwama.Gcina esitolo esipholile, esinomoya, esomile nesimnyama.Akumele ibekwe eduze namapayipi amanzi aphezulu naphansi kanye nemishini yokushisa, ukuvimbela umswakama, ukuwohloka kokushisa.Gcina kude nomlilo, imithombo yokushisa, ama-oxidants nokudla.Izinto zokuhamba kufanele zihlanzeke, zome futhi zivikeleke elangeni nasemvuleni ngesikhathi sokuthutha.
