Umkhiqizi Intengo Enhle I-Oxalic Acid CAS: 144-62-7
I-Oxalic acid iyi-dicarboxylic acid enamandla etholakala ezitshalweni eziningi nemifino, ngokuvamile njenge-calcium noma usawoti we-potassium.I-Oxalic acid iyona kuphela inhlanganisela engenzeka lapho amaqembu amabili e-carboxyl ehlanganiswa ngokuqondile;ngenxa yalesi sizathu i-oxalic acid ingenye ye-organic acid enamandla kakhulu.Ngokungafani namanye ama-carboxylic acid (ngaphandle kwe-formic acid), i-oxidized kalula;lokhu kwenza kube usizo njenge-ejenti yokunciphisa ukuthwebula izithombe, ukuhlanza, nokususwa kwe-inki.I-oxalic acid ivamise ukulungiselelwa ngokushisisa i-sodium formate ne-sodium hydroxide ukuze yakhe i-sodium oxalate, eguqulwa ibe yi-calcium oxalate futhi iphathwe nge-sulfuric acid ukuze kutholakale i-oxalic acid yamahhala.
Izinga le-oxalic acid liphansi kakhulu ezitshalweni eziningi nasekudleni okusekelwe ezitshalweni, kodwa kunesipinashi, i-chard kanye nemifino yebhitrudi ukuze iphazamise ukumuncwa kwe-calcium lezi zitshalo nazo.
Ikhiqizwa emzimbeni nge-metabolism ye-glyoxylic acid noma i-ascorbic acid.Ayifakwanga i-metabolized kodwa ikhishwa emchamweni.Isetshenziswa njenge-reagent yokuhlaziya kanye ne-ejenti yokunciphisa jikelele.I-Oxalic acid iyi-acaricide yemvelo esetshenziselwa ukwelapha izibungu ze-varroa emakoloni angenayo ama-brood, amaphakheji, noma izixuku.I-vaporized oxalic acid isetshenziswa abanye abafuyi bezinyosi njengesibulala-zinambuzane ngokumelene ne-Varroa mite eyisinambuzane. -
Umkhiqizi Intengo Enhle I-Xanthan Gum Industrial grade CAS:11138-66-2
I-Xanthan gum, eyaziwa nangokuthi i-Hanseonggum, iwuhlobo lwe-microbial exopolysaccharide ekhiqizwa yi-Xanthomnas campestris ene-carbohydrate njengento eyinhloko eluhlaza (njengesitashi sombila) ngokusebenzisa ubunjiniyela bokuvutshelwa.Ine-rheology eyingqayizivele, ukuncibilika kwamanzi okuhle, ukuzinza ekushiseni kanye nesisekelo se-asidi, futhi inokuhambisana okuhle nezinhlobonhlobo zosawoti.Njenge-ejenti yokuqina, i-ejenti yokumiswa, i-emulsifier, i-stabilizer, ingasetshenziswa kabanzi ekudleni, ku-petroleum, kwezokwelapha nakwezinye izimboni ezingaphezu kuka-20, okwamanje iyisilinganiso sokukhiqiza esikhulu kunazo zonke emhlabeni kanye ne-microbial polysaccharide esetshenziswa kakhulu.
I-Xanthan gum iyimpushana esusekayo ephuzi kuya kokumhlophe, iyanuka kancane.Incibilika emanzini abandayo nashisayo, isixazululo esingathathi hlangothi, imelana nokubanda nokuncibilika, ayincibiliki ku-ethanol.Ukuhlakazwa kwamanzi, i-emulsification ibe i-hydrophilic viscous colloid ezinzile.

Umkhiqizi Intengo Enhle I-DINP Ibanga Lemboni CAS:28553-12-0
I-Diisononyl phthalate (DINP):Lo mkhiqizo uwuketshezi olunamafutha olusobala olunephunga elincane.I-plasticizer eyinhloko enemisebenzi eminingi enezakhiwo ezinhle kakhulu.Lo mkhiqizo uncibilika ku-PVC, futhi ngeke unake ngisho noma usetshenziswe ngobuningi.I-Volatilization, ukufuduka kanye nokungewona ubuthi kungcono kune-DOP (dioctyl phthalate), enganikeza umkhiqizo ukumelana nokukhanya okuhle, ukumelana nokushisa, ukumelana nokuguga kanye nezakhiwo zokufakwa kukagesi, kanye nokusebenza okuphelele kungcono kune-DOP.Ngenxa yokuthi imikhiqizo ekhiqizwa yilo mkhiqizo inokumelana okuhle kwamanzi nokumelana nokukhipha, ubuthi obuphansi, ukumelana nokuguga, ukusebenza okuhle kakhulu kokufakwa kukagesi, ngakho-ke isetshenziswa kabanzi kufilimu yokudlala, ucingo, ikhebula.
Uma kuqhathaniswa ne-DOP, isisindo samangqamuzana sikhulu futhi side, ngakho sisebenza kangcono ukuguga, ukumelana nokufuduka, ukusebenza kwe-anticairy, kanye nokumelana okuphezulu kwezinga lokushisa.Ngokuhambisanayo, ngaphansi kwezimo ezifanayo, umphumela we-plasticization we-DINP mubi kancane kune-DOP.Kukholelwa ukuthi i-DINP ihambisana kakhulu nemvelo kune-DOP.
I-DINP ingcono kakhulu ekuthuthukiseni izinzuzo ze-extrusion.Ngaphansi kwezimo ezijwayelekile zokucubungula i-extrusion, i-DINP inganciphisa ukuncibilika kwe-viscosity yengxube kune-DOP, esiza ukwehlisa ukucindezela kwemodeli yembobo, ukunciphisa ukuguga komshini noma ukukhulisa ukukhiqiza (kufika ku-21%).Asikho isidingo sokushintsha ifomula yomkhiqizo nenqubo yokukhiqiza, akukho ukutshalwa kwezimali okwengeziwe, akukho ukusetshenziswa kwamandla okwengeziwe, nokugcina ikhwalithi yomkhiqizo.
I-DINP ngokuvamile iwuketshezi olunamafutha, olungancibiliki emanzini.Ngokuvamile zithuthwa ngamathangi, amabhakede amancane ensimbi noma imiphongolo yepulasitiki ekhethekile.
Enye yezinto zokusetshenziswa eziyinhloko ze-DINP -INA (INA), okwamanje izinkampani ezimbalwa kuphela emhlabeni ezingakhiqiza, njenge-United States' Exxon Mobil, inkampani ewinayo yaseJalimane, Inkampani yaseJapan iConcord, kanye nenkampani yaseSouth Asia eTaiwan.Njengamanje, ayikho inkampani yasekhaya ekhiqiza i-INA.Bonke abakhiqizi abakhiqiza i-DINP eShayina bonke kudingeka ukuthi bavele ezintweni ezithengwayo.
