Dibutyltin Maleate
Dibutyltin Maleate (DBTM) ndi chinthu chogwiritsidwa ntchito mosiyanasiyana chomwe chimagwiritsidwa ntchito makamaka ngati chothandizira, chokhazikika pa kutentha, komanso cholumikizirana m'mafakitale a polima ndi mankhwala.
Chothandizira:Popanga thovu la polyurethane (PU), ma elastomer, zokutira, ndi zomatira, zomwe zimathandiza kuti pakhale mgwirizano pakati pa isocyanates ndi polyols. Zimathandizanso pakupanga esterification, transesterification, ndi condensation reactions, zomwe zimathandiza kuti pakhale mgwirizano wabwino pakati pa kupanga ndi kupanga resin.
Chokhazikitsa PVC:Imagwira ntchito ngati choletsa kutentha bwino pazinthu za polyvinyl chloride (PVC), kuteteza kusintha kwa mtundu ndi kuwonongeka panthawi yokonza kutentha kwambiri, komanso kukulitsa kusinthasintha, kuwonekera bwino, komanso moyo wautali wa zinthu za PVC. Siziwononga sulfure komanso sizimatentha kwambiri kwa nthawi yayitali.
Wothandizira Kulumikiza:Amagwiritsidwa ntchito ngati chothandizira cholumikizirana mu rabara ya silicone, ma resins a polyester osakhuta, ndi machitidwe ena a polima kuti awonjezere kuuma kwa chinthucho, mawonekedwe a makina, komanso kukana kutentha.
Ntchito Zina:Amagwiritsidwanso ntchito popanga mankhwala achilengedwe, monga chowonjezera chogwira ntchito mu silicone ndi organotin chemistry, komanso mwina ngati mankhwala oletsa kugwedezeka kwa mafuta.

25kg/ng'oma kapena malinga ndi zosowa za makasitomala.
H302: Ndi yoopsa ngati itamezedwa.
H313: Zingakhale zoopsa zikakhudzana ndi khungu.
H314: Imayambitsa kupsa kwambiri pakhungu ndi kuwonongeka kwa maso.
H317: Zingayambitse vuto la khungu.
H330: Imapha munthu akaipumira.
H341: Akukayikiridwa kuti akuyambitsa zolakwika za majini.
H360: Ikhoza kuwononga chonde kapena mwana wosabadwa.
H372: Zimayambitsa kuwonongeka kwa ziwalo chifukwa chogwiritsidwa ntchito nthawi yayitali kapena mobwerezabwereza.
H411: Ndi poizoni kwa zamoyo zam'madzi zomwe zimakhala ndi zotsatirapo zokhalitsa.

Kusamalira
Valani zida zoyenera zodzitetezera (PPE): magolovesi, magalasi oteteza, zoteteza nkhope, ndi zoteteza kupuma (makamaka m'malo opanda mpweya wabwino) kuti mupewe khungu, kuyang'ana m'maso, komanso kupuma fumbi kapena nthunzi.
Pewani kukhudza khungu, maso, ndi zovala. Ngati zakhudzana ndi khungu kapena tsitsi, chotsani nthawi yomweyo zovala zonse zodetsedwa ndipo tsukani bwino malo okhudzidwawo ndi madzi kapena shawa; tsukani zovala zodetsedwa musanagwiritsenso ntchito. Ngati zakhudzana ndi maso, tsukani nthawi yomweyo ndi madzi ambiri kwa mphindi zosachepera 15, chotsani magalasi olumikizana ngati n'kosavuta kuchotsa, ndipo pitirizani kutsuka.
Musadye, kumwa, kapena kusuta fodya mukamagwira. Sambani m'manja bwino mukagwira komanso musanadye, kumwa, kapena kusuta.
Gwirani pamalo opumira mpweya wabwino (makamaka panja kapena pamalo ophikira utsi) kuti fumbi kapena nthunzi zisaunjikane. Musapume fumbi, nthunzi, kapena nthunzi.
Pezani malangizo apadera musanagwiritse ntchito ndipo musagwiritse ntchito mpaka njira zonse zodzitetezera zitawerengedwa ndikumveka bwino. Sungani nthawi yomweyo kuti mupewe kuipitsidwa kwa chilengedwe.
Malo Osungirako
Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yodutsa mpweya wabwino. Kutentha koyenera kosungirako: 2 - 8 °C pansi pa mpweya wopanda mpweya (nayitrogeni kapena argon); njira ina: 5 - 30 °C kapena kutentha kwa chipinda pamalo ozizira, amdima (< 15 °C).
Sungani chidebecho chitsekedwe bwino ngati sichikugwiritsidwa ntchito kuti chisayamwitse chinyezi, kuipitsidwa, komanso fumbi lisatuluke. Sungani pamalo otsekedwa kuti muchepetse kulowa.
Sungani kutali ndi kutentha, zipsera, malawi otseguka, ndi zinthu zamphamvu zopangitsa kuti zinthu zisawonongeke (monga peroxides, nitric acid). Pewani kukhudzana ndi zipsera ndi maziko amphamvu chifukwa cha kusagwirizana.
Musasunge pamodzi ndi chakudya, chakudya, kapena mankhwala kuti mupewe kuipitsidwa ndi zinthu zina.
