| Tae | ma |
| Hongi (Odor) | te kakara benzaldehyde paku. He kawa, he atawhai |
| Te rohe whakakitenga | TLV-TWA 5 mg/m3; IDLH 7000mg / m3. |
| Te pumau | he hāora kaha. Tino muramura. Kaua e orohina, kaua e pangia, kaua e mirimiri. He hotokore ki nga matū whakaheke, waikawa, turanga, waipiro, konganuku, me nga mea waro. Ko te whakapiri, te whakamahana, te waku ranei ka puta he ahi, he pahūtanga ranei. |
| Te ahua | te paura ma, te totoka wai kirikiri ranei |

Mhe tono:Kei te whakamahia te reira rite monomer polymerization initiator o PVC, polyester haunga, polyacrylate, engari whakamahia ano hoki hei kaihoko ripeka-hono o polyethylene, a whakamahia rite māngai whakaora o te kapia polyester hānga, whakamahia rite tauhohenga tātari, hāora me te bleaching kaihoko; hei whakamaarama mo te kounga o te paraoa, he huakita huakita me te kaha o te waikura, e taea ai te whakamau paraoa.
Te takai:20 Kg, 25 Kg, peeke PE o roto, kaata o waho, kaata peere peere ranei, kei raro iho i te 35 ℃ ka rongoa ki tetahi waahi hauhautanga. Tuhipoka: Kia hiritia te kete, mahara kia ngaro te wai, ka raru.
Nga whakaritenga waka:Ko Benzoyl peroxide no te oxidant pararopi tuatahi. Nama morearea: 22004. Me tohuhia te ipu ki te "peroxide organic" kia kaua e uru ki roto nga kaihihi.
āhuatanga mōrearea:I roto i te mea pararopi, te whakaheke i te kaihoko, te whanariki, te ūkuikui me te mura ahi, te marama, te paanga, te wera nui te mura; auahi whakaihiihi wera.
Nga mahi whawhai ahi:Mena he ahi, me tineia te ahi ki te wai i te waahi aukati pahū. Mena he ahi kei te taha o tenei matū, me whakamatao te ipu ki te wai. I roto i nga ahi nui, me tere tonu te wehe i te waahi ahi. Ko nga mahi horoi me te whakaora i muri i te ahi kaua e mahia i mua i te whakamataotanga o te peroxide. Mena ka pakaru mai i te ahi, i te whakamahi ranei, me konatunatua te rerenga ki te vermiculite makuku wai, ka horoi (kaore he konganuku, he taputapu muka ranei), ka tuu ki roto i te ipu kirihou mo te maimoatanga tonu.
Nga tikanga tuku para e taunakitia ana:Ko te maimoatanga o mua ko te pirau me te natridium hydroxide. Ka mutu, ka ringihia te wairewa konutai konutai benzene (whakaahua) ki te awaawa. Ko te nui o te maimoatanga otinga me whakatika te pH i mua i te tukunga ki roto i te parakaingaki, i muri ranei i te konatunatua ki te hinu kore, hei whakahaere i te tahuna. Ko nga ipu waikore me tahu ki tawhiti, ka horoia ranei ki te otinga NaOH 10%.
