PETO CAS 115-77-5

Pentaerythritol, abbreviated li PETO thiab tseem hu ua 2,2,2',2'-tetrakis(hydroxymethyl)-3,3'-oxydipropan-1-ol, PETO CAS 115-77-5, molecular mis ntawm C₅H₁₂O₅H₁₂O₄. Nws zoo nkaus li cov hmoov dawb crystalline nrog lub melting point ntawm 260℃thiab lub boiling point ntawm 276 degree. Soluble hauv dej thiab me ntsis soluble hauv ethanol, nws yog insoluble hauv benzene, ether, thiab roj av ether. Chemically, nws yog yooj yim esterified los ntawm cov organic acids thiab qhia tsis muaj cov tshuaj tiv thaiv thaum boiled nrog dilute caustic soda tov. Reacting nrog nitric acid tsim oxalic acid, thaum reacting nrog chromium trioxide yields formic acid thiab carbon dioxide. Tus cwj pwm los ntawm qhov tsis tshua muaj toxicity thiab flammability, nws yog ib qho tseem ceeb raw khoom rau alkyd resin ntau lawm.

Txheej kev lag luam:Raws li cov khoom siv tseem ceeb rau alkyd resin coatings, nws txhim kho lub hardness, gloss, thiab durability ntawm cov xim zaj duab xis. Nws kuj tseem siv los tsim cov rosin resins rau xim xim, kua roj vanish, thiab luam ntawv inks, nrog rau cov roj kom qhuav, nplaim taws- cov coatings retardant, thiab aviation lubricants.
Lubricants & Plasticizers:Fatty acid esters ntawm pentaerythritol ua raws li qib siab -cov roj nplua nyeem thiab PVC plasticizers. Nws cov epoxy derivatives yog raw cov ntaub ntawv uas tsis yog - ionic surfactants.
Detergents & Adhesives:Nws ua hauj lwm raws li ib tug dej softener nyob rau hauv detergent formulations. Ua ke nrog ammonium polyphosphate (APP), nws tsim intumescent nplaim retardants rau cov nplaum. Nws kuj ua hauj lwm raws li ib tug polyurethane crosslinker los txhim kho cov ceg saw hlau ntawm cov ntaub ntawv.
Cov tshuaj zoo:Nws yog ib qho nruab nrab rau cov tshuaj thiab tshuaj tua kab. Nitration tsim pentaerythritol tetranitrate (PETN), muaj zog tawg; esterification yields pentaerythritol triacrylate (PETA) rau txheej.

• Khaws rau hauv qhov chaw txias, zoo -ventilated warehouse kom deb ntawm qhov hluav taws kub thiab cua sov. Khaws cais ntawm oxidants thiab acids.
• Ntim rau hauv hnab yas lined nrog polypropylene woven hnab los yog hnab.
• Kev Ceeb Toom Tseem Ceeb: Pentaerythritol hmoov av tsim cov khoom sib xyaw nrog huab cua thaum qhov siab tshaj 30g / m³, thiab tej zaum yuav tawg thaum kub tshaj 400 degree. Ua raws li kev khaws cia tshuaj thiab kev thauj mus los.

ZIBO CHEMIC muab kev lag luam - qib pentaerythritol (PETO CAS 115-}77-5) cov khoom lag luam nrog cov purity ruaj khov, ua tau raws li cov kev xav tau loj ntawm cov txheej txheej, resin, thiab kev lag luam tshuaj zoo. Txais tos kom nug txog cov ncauj lus kom ntxaws specifications thiab hais.

Q: Lub luag haujlwm tshwj xeeb dab tsi yog pentaerythritol ua si hauv alkyd resin txheej?
A: Raws li ib tug tseem ceeb crosslinking monomer, nws txhim khu lub hardness, gloss, thiab huab cua tsis kam ntawm cov xim zaj duab xis, txhim kho kom qhuav ceev thiab adhesion, thiab yog haum rau high - kawg industrial thiab civil xim ntau lawm.
Q: Dab tsi yog qhov kev txwv nruj rau pentaerythritol?
A: Khaws rau hauv qhov chaw txias, qhuav, zoo - lub tsev tso cua txias nrog cov av noo tswj ntawm 50% ~ 70% thiab kub tsis tshaj 30 degree. Cais tawm ntawm oxidants thiab acids, thiab nruj me ntsis txwv tsis pub qhib nplaim taws nyob rau hauv lub warehouse.
Q: Dab tsi yog qhov zoo ntawm pentaerythritol ua polyurethane crosslinker?
A: Nws cov molecule muaj 4 pawg hydroxymethyl zoo ib yam, ua kom muaj kev sib txuam sib luag, muab cov qauv saw hlau ruaj khov rau polyurethane, txhim kho tensile lub zog thiab kev laus tiv thaiv, thiab ua kom muaj kev sib raug zoo.
Q: Yuav ua li cas tiv thaiv kev tawg ntawm pentaerythritol hmoov av?
A: Tswj cov plua plav concentration hauv qhov kev cob qhia hauv qab 30g / m³, nruab qhov tawg - cov khoom siv pov thawj qhov cua; cov neeg ua haujlwm yuav tsum hnav khaub ncaws tiv thaiv- ua haujlwm zoo li qub; tsis tu ncua ntxuav cov plua plav thiab tsis txhob sib cuag nrog siab - ib puag ncig kub.
Q: Pentaerythritol puas tuaj yeem siv rau hauv kev tsim khoom noj-cov ntaub ntawv ntim khoom?
A: Industrial- cov khoom qib tsis haum rau cov khoom noj khoom haus. Khoom noj khoom haus- qib tshwj xeeb yuav tsum tau muaj rau cov ntawv thov no, thiab ZIBO CHEMIC tuaj yeem muab cov khoom noj khoom haus kho tau- qib khoom.

Q: Txoj kev yooj yim them nyiaj yog dab tsi?
A: L / C, T / T, Paypal, Western Union thiab Escrow tau txais, thiab yog tias koj muaj lub tswv yim zoo, thov koj xav qhia rau peb
Q: Hom kev thauj mus los twg yuav zoo dua?
A: Feem ntau, peb tawm tswv yim ua kom xa khoom los ntawm hiav txwv uas pheej yig thiab nyab xeeb.Tseem peb hwm koj cov kev xav ntawm lwm yam kev thauj mus los.
