Soo saaraha Qiimaha Wanaagsan Oxalic Acid CAS: 144-62-7
Oxalic acid waa dicarboxylic acid xoog leh oo ku dhacda dhir iyo khudaar badan, badiyaa sida kalsiyumka ama cusbada potassium.Oxalic acid waa xarunta kaliya ee suurtogalka ah ee laba kooxood oo karboksyl ah ay si toos ah ugu biiraan;Sababtaas awgeed oxalic acid waa mid ka mid ah acids organic ugu xooggan.Si ka duwan asiidhyada karboksilic ee kale (marka laga reebo formic acid), si sahal ah ayaa oksaydhaysan loo sameeyaa;Tani waxay ka dhigaysaa mid waxtar u leh sidii wakiilka yaraynta sawir qaadista, bleaching, iyo ka saarista khad.Oxalic acid waxaa badanaa lagu diyaariyaa kuleylinta sodium hydroxide oo leh sodium hydroxide si loo sameeyo sodium oxalate, taas oo loo beddelo oxalate calcium waxaana lagu daaweeyaa sulfuric acid si loo helo oxalic acid bilaash ah.
Heerarka oxalic acid aad bay ugu hooseeyaan inta badan dhirta iyo cuntooyinka dhirta ku salaysan, laakiin waxaa ku filan isbinaajka, chard iyo cagaarka dabocase si ay u farageliyaan nuugista calcium ee dhirtaas sidoo kale ku jira.
Waxaa lagu soo saaraa jirka iyada oo loo marayo dheef-shiid kiimikaad glycoxylic acid ama ascorbic acid.Lama dheefi karo ee waxa ay ka soo baxdaa kaadida.Oxalic acid waa acaricide-dabiici ah oo loo isticmaalo daawaynta caarada varroa ee gumeysiga aan lahayn/hooseeya, baakado, ama raxan.Acid oxalic uumi ah ayay qaar ka mid ah beeralayda shinnidu u adeegsadaan cayayaan ka dhan ah caarada Varroa. -
Soo saaraha Qiimaha Wanaagsan Heerka Warshadaha Xanthan Xabkaha CAS: 11138-66-2
Xanthan xanjo, oo sidoo kale loo yaqaan Hanseonggum, waa nooc ka mid ah microbial exopolysaccharide kaas oo ay soo saarto Xanthomnas campestris oo leh karbohaydrayt sida walxo ceeriin ah (sida istaarijka galleyda) iyada oo loo marayo injineernimada halsano.Waxay leedahay rheology gaar ah, milanka biyaha wanaagsan, xasilloonida kulaylka iyo saldhigga aashitada, waxayna leedahay ku habboonaanta cusbada kala duwan.Sida wakiilka dhumucdiisuna, wakiilka ganaax, emulsifier, stabilizer, waxaa si ballaaran loo isticmaali karaa in cuntada, batroolka, daawada iyo wax ka badan 20 warshadaha, hadda waa miisaanka wax soo saarka ugu weyn ee adduunka iyo polysaccharide microbial aad loo isticmaalo.
Xanthan xanjo waa huruud khafiif ah iyo budo la qaadi karo oo cad, waxyar ur ah.Ku milmay biyo qabow iyo kulul, xal dhexdhexaad ah, adkaysi u qaboojinta iyo dhalaalidda, aan milmin ee ethanol.Kala firdhinta biyaha, emulsification galay kolloid viscous hydrophilic deggan.

Soo saaraha Qiimaha Wanaagsan DINP heerka warshadaha CAS: 28553-12-0
Diisononyl phthalate (DINP)：Alaabtani waa dareere saliid leh oo hufan oo leh ur yar.Waa balaastiiste weyn oo kala duwan oo leh sifooyin aad u wanaagsan.Alaabtani waxay ku milmaysaa PVC, mana soo da'i doonto xitaa haddii loo isticmaalo tiro badan.Volatilization, hijrada iyo sun la'aanta ayaa ka fiican DOP (dioctyl phthalate), kaas oo ku siin kara sheyga caabbinta iftiinka wanaagsan, caabbinta kulaylka, caabbinta gabowga iyo sifooyinka korantada, iyo waxqabadka dhamaystiran ayaa ka fiican DOP.Sababtoo ah alaabada ay soo saartay alaabtani waxay leeyihiin caabbinta biyaha wanaagsan iyo iska caabinta soo saarista, sunta hoose, caabbinta gabowga, waxqabadka korantada ee aad u fiican, sidaas darteed waxaa si ballaaran loo isticmaalaa filimka toy, fiilada, fiilada.
Marka la barbar dhigo DOP, miisaanka unugyadu wuu ka weyn yahay oo wuu dheer yahay, markaa waxay leedahay waxqabadka gabowga oo ka wanaagsan, caabbinta socdaalka, waxqabadka anticairy, iyo iska caabin heerkul sare oo sarreeya.Isla sidaas oo kale, isla shuruudo isku mid ah, saamaynta balaastikada ee DINP ayaa ka yara xun DOP.Waxaa guud ahaan la rumeysan yahay in DINP ay deegaan ahaan uga wanaagsan tahay DOP.
DINP waxay leedahay heer sare xagga hagaajinta faa'iidooyinka extrusion.Marka la eego xaaladaha wax-soo-saarka extrusion-ka caadiga ah, DINP waxay yarayn kartaa viscosity dhalaalka ee isku dhafka ah marka loo eego DOP, taas oo ka caawisa yaraynta cadaadiska qaabka dekedda, yaraynta xirashada farsamada ama kordhinta wax soo saarka (ilaa 21%).Looma baahna in la beddelo caanaha alaabta iyo habka wax soo saarka, ma jirto maalgashi dheeri ah, ma jirto isticmaalka tamarta dheeraadka ah, iyo ilaalinta tayada alaabta.
DINP caadi ahaan waa dareere saliid leh, oo aan lagu milmi karin biyaha.Guud ahaan waxaa lagu qaadaa booyado, baaldiyo bir ah oo yar yar ama fuustooyin caag ah oo gaar ah.
Mid ka mid ah alaabta ceeriin ee ugu muhiimsan ee DINP -INA (INA), hadda kaliya dhowr shirkadood oo adduunka ah ayaa soo saari kara, sida Maraykanka Exxon Mobil, shirkadda Jarmalka ee ku guuleysatay, Shirkadda Concord ee Japan, iyo shirkadda Koonfurta Aasiya ee Taiwan.Waqtigan xaadirka ah, ma jiro shirkad gudaha ah oo soo saarta INA.Dhammaan warshadeeyayaasha soo saara DINP ee Shiinaha ayaa dhamaantood looga baahan yahay inay ka yimaadaan soo dejinta.
