Isopropanol Yogwira Ntchito Zambiri: Chosungunulira Cha Mafakitale Cholondola
Fomula ya molekyulu:C₃H₈O
Isopropyl Alcohol (IPA) ndi mankhwala ofunikira komanso ogwiritsidwa ntchito m'njira zosiyanasiyana, makamaka omwe amagwira ntchito ngati chosungunulira chabwino kwambiri komanso chothandizira kwambiri pamakampani. Monga chosungunulira, Isopropyl Alcohol ndi yofunika kwambiri chifukwa cha mphamvu yake yochotsa mafuta komanso kusungunuka mwachangu. Ndi chinthu chofunikira kwambiri popanga mankhwala ophera tizilombo toyambitsa matenda, zotsukira m'manja, zotsukira zamagetsi, ndi zokutira. Kupatula ntchito yake ngati chosungunulira, Isopropyl Alcohol imagwira ntchito ngati chothandizira kwambiri pakupanga zinthu zachilengedwe, makamaka popanga acetone ndi mankhwala osiyanasiyana. Kufunika kwa mitundu yoyera kwambiri, makamaka pa zamagetsi ndi chisamaliro chaumoyo, kukuwonetsa kufunika kwake. Kaya imagwiritsidwa ntchito ngati chothandizira chogwira ntchito mu mankhwala ophera tizilombo kapena ngati chosungunulira choyeretsa molondola komanso chothandizira pa mankhwala, Isopropyl Alcohol ikadali gawo lofunikira kwambiri pamakampani opanga, kukonza, ndi ukhondo padziko lonse lapansi. Ubwino wake wokhazikika komanso kupezeka kwake kodalirika ndikofunikira kwambiri pa zomangamanga zamakampani ndi zaumoyo padziko lonse lapansi.

Fomula ya molekyulu: C8H8
Styrene ndi chinthu chofunikira kwambiri cha petrochemical komanso polymer monomer yogwiritsidwa ntchito kwambiri m'mafakitale apadziko lonse lapansi. Madzi amafuta opanda mtundu, owonekera bwino awa omwe ali ndi fungo lonunkhira bwino samasungunuka m'madzi koma amatha kusakanikirana ndi zinthu zambiri zachilengedwe, zomwe zimapangitsa kuti styrene ikhale chinthu chofunikira kwambiri popanga pulasitiki. Monga gawo lapakati, styrene imagwiritsidwa ntchito kwambiri popanga polystyrene, ABS resin, ndi rabara yopangidwa, zomwe zimapangitsa kuti pakhale zatsopano mu ma paketi, zomangamanga, ndi magalimoto. Chodziwika bwino n'chakuti, styrene imakonda kupangidwa polymerization kutentha kwa chipinda, kotero zoletsa monga hydroquinone ndizofunikira kuti zisungidwe bwino komanso kunyamulidwa. Chifukwa cha mphamvu zake zokhazikika zamakemikolo komanso kugwiritsidwa ntchito kwakukulu, styrene ikadali maziko opangira ma polima amakono, kuthandizira maunyolo osiyanasiyana amafakitale padziko lonse lapansi.

Cyclohexanone Yoyera Kwambiri: Chosungunulira Chamakampani Chosiyanasiyana
Fomula ya molekyulu:C₆H₁₀O
Cyclohexanone ndi chinthu chofunikira kwambiri chachilengedwe chomwe chimagwiritsidwa ntchito kwambiri ngati chosungunulira champhamvu kwambiri m'mafakitale opangira zinthu. Mphamvu yake yapamwamba kwambiri yosungunulira imapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito popanga chikopa chopangidwa, kukonza zokutira za polyurethane, komanso kupanga inki zosindikizira, komwe kumatsimikizira kuti imakhala yosalala komanso yogwirizana. Kupatula ntchito yake ngati chosungunulira, cyclohexanone ndi chinthu chofunikira kwambiri popanga mankhwala, makamaka popanga mankhwala ophera udzu, zothamangitsa rabara, ndi mankhwala ena. Kugwira ntchito kophatikizana kumeneku monga chosungunulira chachikulu komanso choyambira kukuwonetsa kufunika kwake m'magawo osiyanasiyana opangira zinthu, zomwe zimapangitsa kuti zinthu zatsopano zikhale zabwino komanso zabwino pazinthu zomaliza.

Mtengo Wabwino Wopanga Oxalic Acid CAS：144-62-7
Oxalic acid ndi dicarboxylic acid yamphamvu yomwe imapezeka mu zomera ndi ndiwo zamasamba zambiri, nthawi zambiri imakhala mchere wake wa calcium kapena potaziyamu. Oxalic acid ndiye chinthu chokhacho chomwe magulu awiri a carboxyl amalumikizidwa mwachindunji; pachifukwa ichi oxalic acid ndi imodzi mwa ma organic acid amphamvu kwambiri. Mosiyana ndi ma carboxylic acid ena (kupatula formic acid), imasungunuka mosavuta; izi zimapangitsa kuti ikhale yothandiza ngati chochepetsera kujambula zithunzi, kuyera, komanso kuchotsa inki. Oxalic acid nthawi zambiri imakonzedwa potenthetsa sodium formate ndi sodium hydroxide kuti ipange sodium oxalate, yomwe imasinthidwa kukhala calcium oxalate ndikuchiritsidwa ndi sulfuric acid kuti ipeze oxalic acid yaulere.
Kuchuluka kwa oxalic acid m'zakudya zambiri ndi zomera n'kochepa, koma mu sipinachi, chard ndi beet greens muli zokwanira kuti calcium isalowe m'thupi zomwe zomerazi zili nazo.
Imapangidwa m'thupi kudzera mu kagayidwe ka glyoxylic acid kapena ascorbic acid. Siigayidwa koma imatulutsidwa mu mkodzo. Imagwiritsidwa ntchito ngati chothandizira kusanthula komanso chochepetsera. Oxalic acid ndi acaricide yachilengedwe yomwe imagwiritsidwa ntchito pochiza nthata za varroa m'magulu omwe alibe ana, mapaketi, kapena magulu. Oxalic acid yotenthedwa ndi nthunzi imagwiritsidwa ntchito ndi alimi ena a njuchi ngati mankhwala ophera tizilombo toyambitsa matenda a Varroa mite. -
Mtengo Wabwino Wopanga Xanthan Gum CAS Yogulitsa: 11138-66-2
Xanthan chingamu, yomwe imadziwikanso kuti Hanseonggum, ndi mtundu wa exopolysaccharide ya tizilombo toyambitsa matenda yomwe imapangidwa ndi Xanthomnas campestris yokhala ndi chakudya chambiri (monga chimanga) kudzera muukadaulo wa fermentation. Ili ndi rheology yapadera, kusungunuka bwino kwa madzi, kukhazikika kutentha ndi maziko a asidi, ndipo imagwirizana bwino ndi mchere wosiyanasiyana. Monga chinthu chokhuthala, chosungunula, emulsifier, stabilizer, chingagwiritsidwe ntchito kwambiri mu chakudya, mafuta, mankhwala ndi mafakitale ena opitilira 20, pakadali pano ndi mtundu waukulu kwambiri padziko lonse lapansi wopanga ndipo polysaccharide ya tizilombo imagwiritsidwa ntchito kwambiri.
Xanthan chingamu ndi ufa wosunthika wachikasu mpaka woyera, wonunkha pang'ono. Umasungunuka m'madzi ozizira ndi otentha, umasungunuka bwino, sungathe kuzizira kapena kusungunuka, susungunuka mu ethanol. Umafalikira m'madzi, umasungunuka kukhala colloid yolimba ya hydrophilic viscous.

Mtengo Wabwino Wopanga DINP Industrial grade CAS：28553-12-0
Diisononyl phthalate (DINP)：Chogulitsachi ndi chamadzimadzi chowoneka bwino chamafuta chokhala ndi fungo lochepa. Ndi pulasitiki yayikulu yogwiritsidwa ntchito mosiyanasiyana yokhala ndi makhalidwe abwino kwambiri. Chogulitsachi chimasungunuka mu PVC, ndipo sichingagwe ngakhale chitagwiritsidwa ntchito kwambiri. Kusakhazikika, kusamuka komanso kusawononga ndikwabwino kuposa DOP (dioctyl phthalate), yomwe ingapereke mankhwalawa kukana kuwala, kukana kutentha, kukana ukalamba komanso kukana magetsi, ndipo magwiridwe antchito ake onse ndi abwino kuposa DOP. Chifukwa zinthu zomwe zimapangidwa ndi mankhwalawa zimakhala ndi kukana madzi komanso kukana kutulutsa, kukana poizoni pang'ono, kukana ukalamba, komanso kukana magetsi, kotero chimagwiritsidwa ntchito kwambiri mu filimu yoseweretsa, waya, chingwe.
Poyerekeza ndi DOP, kulemera kwa mamolekyulu ndi kwakukulu komanso kotalika, kotero kumakhala ndi magwiridwe antchito abwino okalamba, kukana kusamuka, magwiridwe antchito oletsa kupha, komanso kukana kutentha kwambiri. Mofananamo, pansi pa mikhalidwe yomweyi, mphamvu ya DINP yopangira pulasitiki ndi yoipa pang'ono kuposa DOP. Kawirikawiri amakhulupirira kuti DINP ndi yoteteza chilengedwe kuposa DOP.
DINP ili ndi luso loposa ena onse pakukweza ubwino wa extrusion. Pansi pa mikhalidwe yachizolowezi yogwiritsira ntchito extrusion, DINP imatha kuchepetsa kukhuthala kwa kusungunuka kwa chisakanizocho kuposa DOP, zomwe zimathandiza kuchepetsa kupanikizika kwa chitsanzo cha port, kuchepetsa kuwonongeka kwa makina kapena kuwonjezera zokolola (mpaka 21%). Palibe chifukwa chosinthira njira yopangira zinthu ndi njira yopangira, palibe ndalama zowonjezera, palibe kugwiritsa ntchito mphamvu zowonjezera, komanso kusunga mtundu wa zinthu.
DINP nthawi zambiri imakhala yamafuta, yosasungunuka m'madzi. Nthawi zambiri imanyamulidwa ndi matanki, zidebe zazing'ono zachitsulo kapena migolo yapadera yapulasitiki.
Chimodzi mwa zinthu zazikulu zopangira DINP -INA (INA), pakadali pano ndi makampani ochepa okha padziko lonse lapansi omwe angapange, monga Exxon Mobil yaku United States, kampani yopambana ku Germany, Concord Company yaku Japan, ndi kampani yaku South Asia ku Taiwan. Pakadali pano, palibe kampani yakunyumba yomwe imapanga INA. Opanga onse omwe amapanga DINP ku China onse amafunika kuchokera kumayiko ena.
