8. Soo saarida CO: falcelinta kiimikada: HCOOH= (cufan H2SO4catalyze) kulayl=CO+H2O
9.Deoxidizer: TestAs, Bi,Al,Cu,Au,lm,Fe,Pb,Mn,Hg,Mo,Ag,Zn,iwm milmaya si loo tijaabiyo molecular WT iyo crytallization.Testmethoxyl.Fixer ee falanqaynta microscopic. Soo saarista qaab
10.Formic acid iyo xalkeeda milmi karaa biraha kala duwan, metaloxide, hydroxide iyo cusbo, iyo formate lagu kala diri karaa wakiilka nadiifinta kiimikada wateras. Formic acid waxa kale oo loo isticmaali karaa nadiifinta qalabka isteerinka Staness.Thyteic acid waxa kale oo loo yaqaanaa aashitada. Warshadaha maqaarka, waxaa loo isticmaalaa sida tannai, ash iyo dhexdhexaadiye ee warshadaha maqaarka.
Qiimaha pH ee maqaarka qaawan ee dambaska ka dib waa 7.5 ~ 8.5. Si loo sameeyo maqaarka dambaska ee ku habboon xaaladaha hawlgalka ee isku xigxiga jilicsan, qiimaha pH ee maqaarka qaawan ayaa loo baahan yahay si loo yareeyo 2.5 ~ 3.5 si ay ugu habboonaato tannasis chromium. Habka ugu muhiimsan ee lagu xakameyn karo qiimaha pH waa in lagu qooyo aashitada.
Poin acid waxaa inta badan loo isticmaalaa methamphetamic acid, molecules molecular yar yar, dhexgalka degdega ah, iyo saamaynta maaskarada ee xalinta chromium tannic, taas oo ka dhigaysa isku dhafka metroquats maqaar yar ee maqaarka. Waxaa badanaa lagu isticmaalaa sulfuric acid marka la qooyaynayo.
Intii uu dillaacay dalka, iibka iyo shaqaaluhu waxay sii wadeen iskaashiga, iyo namal acid ee shirkadda, methamphetamine, xalalka acetic acid, sodium solid acetate, sodium dareeraha acetate, calcium phosphate ayaa sii waday shixnadaha, iyo ilaalinta tayada iyo tirada inta lagu jiro cudurka faafa. muddo. Siyaasadda walwalka-la'aanta ka dib iibka ayaa sidoo kale jeclaaday macaamiil badan, iyo Pengfa Chemical ayaa si tartiib tartiib ah u ciyaareysa faa'iidada asaasiga ah si ay u qabsato saamiga suuqa oo ay u hesho raalli ahaanshaha macaamiil badan.
