Chemical katundu
Kusungunuka mu methanol, acetone, benzene, ethanol, ether, kusungunuka pang'ono m'madzi.Lawi lotseguka likhoza kuyaka.Kuwola ndi kutentha kumatulutsa mpweya wapoizoni.Poizoni, pang'onopang'ono imakwiyitsa khungu, mucous nembanemba ndi maso.
Amagwiritsidwa ntchito popanga p-tert-butyl phenolic resin.Itha kugwiritsidwanso ntchito ngati inhibitor ndi stabilizer.Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.Khalani kutali ndi moto, kutentha ndi kuwala.
katundu
Chogulitsachi ndi choyera kapena choyera cholimba kutentha kutentha.Ndi yoyaka koma yosapsa.Lili ndi fungo lapadera la alkyl phenol.Amasungunuka mu mowa, esters, alkanes, ma hydrocarbon onunkhira ndi zosungunulira zina organic, monga ethanol, acetone, butyl acetate, petulo, toluene, sungunuka mu njira yamphamvu ya alkali, sungunuka pang'ono m'madzi.Izi mankhwala ali ndi makhalidwe wamba phenolic zinthu, pokhudzana ndi kuwala, kutentha, kukhudzana ndi mpweya, mtundu pang`onopang`ono kwambiri.

Kugwiritsa ntchito kwakukulu
P-tert-butylphenol ali ndi antioxidant katundu ndipo angagwiritsidwe ntchito ngati stabilizer kwa labala, sopo, chlorinated hydrocarbons ndi ulusi kugaya chakudya.Uv absorbent, mankhwala, mphira, utoto ndi anti cracking agent.Mwachitsanzo, amagwiritsidwa ntchito popanga utomoni wa polycarbon, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Kuphatikiza apo, ndizinthu zopangira mankhwala othamangitsa tizilombo, mankhwala ophera tizilombo ndi ma acaricide, fungo labwino komanso chitetezo cha zomera.Itha kugwiritsidwanso ntchito monga zofewa, zosungunulira, zowonjezera utoto ndi utoto, antioxidant wamafuta opaka mafuta, demulsifier yamafuta ndi zowonjezera zamafuta agalimoto.
Poizoni ndi chilengedwe
Mankhwalawa ndi a poizoni wa mankhwala.Kukoka mpweya, kukhudzana ndi mphuno, maso kapena kuyamwa kumatha kukhumudwitsa maso, khungu ndi mucous nembanemba.Kukhudzana ndi khungu kungayambitse dermatitis ndi chiopsezo chowotcha.Kuwola kwa kutentha kumatulutsa mpweya wapoizoni;
Izi ndi poizoni kwa zamoyo zam'madzi ndipo zitha kukhala ndi zotsatira zoyipa kwa nthawi yayitali pamadzi.Samalani kuopsa kwa chilengedwe cha zinyalala ndi zinthu zomwe zimachokera pakupanga.
Kulongedza katundu, kusunga ndi mayendedwe
Chogulitsacho chimakhala ndi filimu ya polypropylene, yokutidwa ndi thumba la pepala losawala komanso lodzaza mu chidebe cholimba cha makatoni cholemera 25Kg / thumba.Kusunga mu ozizira, mpweya wokwanira, youma ndi mdima nkhokwe.Sadzayikidwa pafupi chapamwamba ndi m'munsi madzi mapaipi ndi Kutentha zida, kuteteza chinyezi, kutentha kuwonongeka.Khalani kutali ndi moto, gwero la kutentha, ma okosijeni ndi chakudya.Zoyendera ziyenera kukhala zoyera, zowuma komanso zotetezedwa ku dzuwa ndi mvula panthawi yoyendera.
