Acrylic Acid

Thawj qhov kev siv ntawm acrylic acid yog nyob rau hauv zus tau tej cov acrylic esters thiab resins, uas yog siv feem ntau nyob rau hauv coatings thiab adhesives. Nws kuj yog siv rau hauv cov tshuaj kho roj, tshuaj ntxuav tes intermediates, tshuaj kho dej, thiab dej absorbent polyacrylic acid polymers. Acrylic acid yog siv dav rau polymerization, nrog rau kev tsim cov polyacrylates. Nws yog monomer rau polyacrylic thiab polymethacrylic acids thiab lwm yam acrylic polymers. Nws yog siv nyob rau hauv kev tsim cov yas, raws li ib tug tackifier, raws li ib tug flocculant, nyob rau hauv zus tau tej cov dej-soluble resins thiab ntsev, raws li ib tug comonomer nyob rau hauv acrylic emulsion thiab kua polymers thiab molding hmoov rau cov paib, kev tsim kho units, hniav emblems thiab kos npe. Nws yog siv nyob rau hauv cov kev daws teeb meem polymer rau coatings daim ntaub ntawv, nyob rau hauv cov xim formulations, nyob rau hauv tawv finishings, nyob rau hauv daim ntawv coatings, nyob rau hauv polishes thiab adhesives thiab nyob rau hauv feem ntau finishes thiab binders.

Weatherability thiab kub tsis kam:Acrylics muaj huab cua zoo thiab ua haujlwm kub thiab muaj peev xwm tswj tau kev ua haujlwm ruaj khov nyob rau ntau qhov kub thiab txias, txawm tias nyob hauv qhov chaw huab cua.

1. Muaj kev npaj cov txheej txheem ntawm acrylic acid
◆ Cov txheej txheem kev lag luam ntawm acrylic acid feem ntau suav nrog txoj kev cyanidation, oxidation method thiab hydrolysis method.
◆ Cyanidation txoj kev yog acrylonitrile tau acrylonitrile acid nitrile los ntawm cyanidation cov tshuaj tiv thaiv, thiab ces tau acrylic acid los ntawm hydrolysis. Txoj kev no yog tus cwj pwm los ntawm kev yooj yim thiab kev ua haujlwm siab, tab sis nws muaj kuab paug rau ib puag ncig.
◆ Oxidation txoj kev yog oxidize acrylonitrile nrog oxygen nyob rau hauv cov huab cua nyob rau hauv qhov kev txiav txim ntawm catalyst los tsim acrylic acid. Txoj kev no yog ib puag ncig tus phooj ywg, tab sis kev xaiv ntawm catalyst thiab kev tswj ntawm cov tshuaj tiv thaiv yog qhov nyuaj dua.
◆ Hydrolysis txoj kev yog los ua acrylonitrile nrog dej los tsim acrylic acid. Txoj kev no yog qhov yooj yim, tab sis kev tswj cov tshuaj tiv thaiv kab mob yog xav tau ntau dua.

2. Cov ntsiab lus thiab cov kauj ruam ntawm kev npaj acrylic acid los ntawm txoj kev cyanidation

(3) Los ntawm distillation thiab lwm txoj kev, acrylic acid yog purified kom tau cov ntshiab acrylic acid.

1. Kev kho deg:Xyuas kom qhov chaw yuav tsum tau ua kom huv si, qhuav thiab tsis muaj roj. Xuab zeb rau saum npoo ntawm cov khoom yuav tsum tau sib txuas los txhim kho adhesion.
2. Sib tov kua nplaum:Sib tov kua nplaum A thiab kua nplaum B raws li cov proportions teev nyob rau hauv cov lus qhia thiab do zoo. Ua tib zoo saib xyuas qhov kev faib ua feem thiab sib tov lub sijhawm kom ntseeg tau tias cov kua nplaum sib xws.
3. Siv kua nplaum:Siv cov kua nplaum sib xyaw acrylic AB rau ntawm qhov chaw kom sib txuas, sim siv cov txheej nyias nyias. Tom qab ntawd kho qhov sib txuas ntawm qhov chaw sib txuas thiab siv lub siab maj mam txhawm rau kom muaj kev sib haum xeeb ntawm ob qho khoom sib txuas.
4. Cia ntawm cov nplaum seem:Tom qab siv cov acrylic AB nplaum ntxiv, nws tuaj yeem khaws cia rau hauv ib txoj hauv kev los tswj nws cov txiaj ntsig.
5. Kev ntsuas kev nyab xeeb:Acrylic topcoat yog flammable, thov kom deb ntawm qhov hluav taws kub. Kev haus luam yeeb yog txwv tsis pub nyob hauv thaj chaw tsim kho.
• Cov huab cua ncig yuav tsum tau tswj xyuas thaum lub sij hawm tsim kho thiab kev tiv thaiv yuav tsum tau ua kom tsis txhob nqus cov vapors hnyav lossis xim pos huab. Cov tawv nqaij thiab qhov muag yuav tsum tsis txhob sib cuag nrog cov roj acrylic ua tiav.
• Cov roj acrylic-raws li topcoat yuav tsum tau nplawm kom zoo ua ntej siv.
• Acrylic roj-raws li tiav lawm yuav tsum tau thinned nrog cov txheej txheem thinner.

Acrylic acid yog ib qho qhib, cyclic organic tshuaj uas muaj ob cov pa roj carbon atom thiab muaj cov chav tsev -COOCH3, uas muaj cov qauv luv luv CH2=CHCOOH. acrylic acid yog ntau [[]] dua lwm cov organic tshuaj, thiab yog li ntawd nws muaj ntau yam kev siv.
Vim tias nws cov khoom siv ob npaug, acrylic acid yog qhov hloov pauv tau yooj yim thiab tuaj yeem siv los tsim cov khoom sib txawv xws li polyurethane roj hmab, hluavtaws roj hmab, cellulose ether, kub stamping roj thiab esters los ntawm kev sib koom tes nrog lwm cov organic tshuaj. Hauv kev kho mob, acrylic acid yog siv rau hauv tib neeg cov ntaub so ntswg engineering, thiab tuaj yeem siv rau kho qhov ncauj kab noj hniav thiab kho daim tawv nqaij, thiab lwm yam.
Acrylic acid kuj tseem siv rau hauv cov khoom noj xws li cocoa hmoov, syrups, candies, thiab flavorings. Tsis tas li ntawd, acrylic acid feem ntau yog siv los ua cov kuab tshuaj siv lwm cov organic xws li inks, xim, lacquers, latex xim, thiab lwm yam.
Acrylic acid yog cov organic tseem ceeb heev uas ua lub luag haujlwm tseem ceeb hauv kev tsim khoom noj thiab lwm yam khoom siv organic. Nrog rau qhov no hauv siab, acrylic acid yuav tsum muaj kev tshawb fawb ntau los txiav txim siab seb yuav siv nws li cas rau tib neeg lub neej.

Kaitai Petrochemical tau tsim nyob rau hauv Lub Xya hli ntuj 2004. Nrog rau kev txhawb zog ntawm tag nrho cov sectors ntawm lub zej zog, nws tsim ib tug subsidiary nyob rau hauv Gaoqing County nyob rau hauv 2011 thiab officially muab tso rau hauv ntau lawm nyob rau hauv Lub kaum hli ntuj 2013. Txij li thaum 2018, Kaitai tau tshiab muab tso rau hauv lub lag luam 180000 tons high- kawg cov roj dawb ua haujlwm ntawm nws cov chaw haujlwm. Kaitai Petrochemical tau tsim los ua ib lub tuam txhab tshuaj lom neeg sib txawv.
Shandong kaitai yog nyob rau hauv zoo nkauj Qi ancient capital- Zibo, uas nyiam superior geographic txoj hauj lwm thiab yooj yim kev khiav hauj lwm- sab qaum teb mus rau Huanghe River, sab hnub tuaj mus rau Qingdao chaw nres nkoj, thiab sab qab teb mus rau lub tshav dav hlau Jinan, Shandong Kaitai yeej tsis tso tseg nws kev rau siab pab cov neeg muas zaub, thiab muag. acrylic acid esters rau feem ntau ntawm Tuam Tshoj thiab txawv teb chaws. Kaitai yog ib qho kev lag luam ua ke nrog acrylic acid, acrylic ester thiab dawb roj ntau lawm.
Shandong Kaitai Petrochemical ua raws li kev lag luam tenet ntawm "kev nrhiav kev txhim kho zoo ntawm kev lag luam, muab nqi zog rau cov tswv lag luam, "Txhim kho qhov kev zoo siab ntawm cov neeg ua haujlwm thiab coj txoj hauv kev ntawm kev vam meej", siv kev tswj hwm hnub ci, txhim kho nrog cov neeg siv khoom, loj hlob nrog cov neeg ua haujlwm. . Ua kom muaj kev lav phib xaub thiab tsim kom muaj kev hwm kev lag luam, ua kom muaj lub luag haujlwm ntawm kev lag luam, tsim kev lag luam nrog cov txiaj ntsig zoo thiab kev cia siab, ua kom cov neeg ua haujlwm nplua nuj ua ke, muaj nyiaj tau los ntau dua, kev noj qab haus huv zoo dua, ntau dua thiab muaj meej mom, tsim kom muaj kev zoo siab, ua neej nyob zoo dua thiab paub txog. npau suav ntawm Kaitai.
Shadong Kaitai muaj ntau tshaj 1000 tus neeg ua haujlwm, suav nrog 200 nrog cov npe nruab nrab thiab cov laus tshaj lij. Shandong Kaitai tau tsim nyog los ua lub teb chaws "peb lub tshuab" ntawv pov thawj kev lag luam; Shandong acrylate Engineering Technology Research Center; High tech enterprises nyob rau hauv Shandong xeev; Shandong ncaj ncees enterprise; "Kaitai" acrylic acid yog cov khoom lag luam nto moo hauv xeev Shandong. Hauv 2019, lub zog muaj zog ntawm Kaitai ranked 42nd ntawm 100 lub tuam txhab saum toj kawg nkaus hauv Zibo.
