Nta & Qhov Zoo
Siab -Purity Linear Monomer
Qhov guaranteed yam tsawg kawg nkaus 99.50% n-butene cov ntsiab lus kom ntseeg tau ib tug zoo ib yam thiab txhim khu kev qha comonomer rau copolymer ntau lawm, ua rau kom paub tseeb tias polymer kev ua tau zoo.
Txhim kho Polymer Properties
Thaum siv los ua ib qho comonomer hauv LLDPE (Linear Low-Density Polyethylene) ntau lawm, nws qhia txog kev tswj xyuas luv luv - chain branching, txhim kho zaj duab xis toughness, yooj, thiab lub zog tsim kua muag.
Critical Chemical Intermediate
Ua haujlwm tseem ceeb rau kev tsim butene-1 oxide, valeraldehyde, thiab lwm yam derivatives siv hauv cov kuab tshuaj, plasticizers, thiab cov tshuaj tshwj xeeb.
Precision Feedstock
Nws cov qib tshwj xeeb ua rau nws haum rau siab - cov txheej txheem tshuaj lom neeg xaiv qhov twg isomer purity cuam tshuam rau kev ua haujlwm catalyst thiab cov khoom zoo.
Cov yam ntxwv ua haujlwm
Qhov no siab -purity n-butene feem ntau ua haujlwm raws li ib tug comonomer hauv Ziegler-Natta los yog metallocene-catalyzed copolymerization nrog ethylene los tsim LLDPE. Thaum lub sij hawm polymerization, cov butene molecules tau muab tso rau hauv cov saw hlau polymer, tsim cov ceg tswj uas txo qhov ntom ntom thiab hloov crystallinity. Nws cov tshuaj reactivity kuj tso cai rau nws mus rau cov tshuaj tiv thaiv xws li hydration los tsim theem nrab butanol, oxidation, thiab oligomerization. Cov khoom yog muab raws li cov roj liquefied nyob rau hauv siab nyob rau hauv lub tog raj kheej, raj trailer, los yog los ntawm pipeline.
Thawj daim ntawv thov teb
Polymer Production (Pib siv)
Qhov tseem ceeb comonomer rau kev tsim LLDPE resins siv rau hauv cov yeeb yaj kiab hloov tau yooj yim ( ntim, ua liaj ua teb, ncab), txhaj tshuaj molding, thiab rotomolding.
Tshuaj Synthesis
Feedstock rau kev tsim butene-1 oxide (siv surfactants, lubricant additives), valeraldehyde (rau cov kuab tshuaj, plasticizer alcohols), thiab linear oligomers (rau hluavtaws lubricants, surfactants).
Kev Hloov Kho Polymer
Siv los hloov cov khoom ntawm polypropylene (kev cuam tshuam copolymer) thiab lwm yam polymers.
Roj & Refining
Cov khoom siv hauv alkylation (kom tsim tau siab - roj av octane) thiab ua cov khoom sib xyaw, txawm tias qib purity siab dua yog feem ntau mob siab rau kev siv tshuaj lom neeg.
Cov neeg siv khoom sib koom tes Case
Ib tug thawj coj ntawm cov neeg tsim khoom zoo tshaj plaws cam khwb cia-stretch zaj duab xis rau kev lag luam pallet wrapping tau tawm tsam nrog zaj duab xis sib xws. Kev hloov pauv hauv comonomer pub tau ua rau muaj kev hloov pauv hauv lub zog tensile thiab kev ua haujlwm ntawm lawv cov LLDPE. Lawv xav tau ib qho tshwj xeeb zoo ib yam, siab -purity n-butene muab los ua tus thawj comonomer. Peb tau koom tes nrog lawv, muab peb 99.50% yam tsawg kawg nkaus n{7}} qib butene los ntawm kev sib txuas ntawm cov kav dej sib txuas nrog tiag - lub sijhawm saib xyuas cov khoom sib xyaw. Qhov zoo ib yam, siab -purity pub pub rau lawv cov catalyst system ua hauj lwm ntawm lub ncov efficiency, ua LLDPE resin nrog ib tug zoo meej luv luv - saw branching faib. Qhov no ua rau txo qis 40% ntawm cov cuab yeej ua yeeb yaj kiab, 15% nce ntxiv hauv qhov kawg elongation, thiab txhim kho kev thauj khoom zoo heev - tuav kev ua haujlwm. Cov khoom siv txhim khu kev qha ntawm peb lub siab -purity n-butene tau dhau los ua lub hauv paus ntawm lawv cov kev tswj hwm zoo, ua rau lawv muaj kev ruaj ntseg ntev - cov ntawv cog lus nrog cov tuam txhab logistics loj thiab ua tus tswj hwm qib siab -kev ua lag luam stretch zaj duab xis ntu.
