gala formaldehyde

Gala formaldehyde markii hore loogu talagalay dyeing ee copolymer cellulose, oo waa biyo-beelaya. formaldehyde waxaa Barandho dhulka ay joogaan ka mid ah wakiilka Firdhisan ah oo iibin sidii koollada ah, ama lagu buufiyo-qalajiyey iyo iibin sidii budada ah. Isticmaalkooda ugu weyn waa in dheeha caag, laakiin waxaa kale oo loo isticmaali karaa in dheeha nylon, triacetate cellulose, iyo macdantaa looxa. Xaaladaha qaarkood, heerkulka dyeing of 130 ° C (266 ° F) waxaa loo baahan yahay, iyo dyebath a cadaadiyay waxaa loo isticmaalaa. The size walxaha aad u wanaagsan siinayaa aag aad u ballaaran dusha in kala diridda qalabka ay u oggolaadaan qaadashada by fiber ah. Heerka dyeing ayaa la si weyn u saamayn kara doorashada ee kala wakiilka loo isticmaalo inta lagu jiro shiididdu.

acid formaldehyde

formaldehyde acid waa formaldehyde anionic biyo-L in lagu dabaqo fiiloyin sida xariir, iyo suufkayga, iyo nylon fiiloyin looxa modified isticmaalaya dhex-dhexaad ah si ay u bad dheeh acid. Lifaaqa in fiber waxaa sababay, ugu yaraan qayb ahaan, in formation cusbo u dhexeeya kooxaha anionic ee formaldehyde iyo kooxaha cationic in fiber ah. formaldehyde Acid ma aha dhab ah in fiiloyin cellulosic. Inta badan midabada cunto dardaro dhici in this category.

Basic formaldehyde

formaldehyde aasaasiga ah waa formaldehyde cationic biyo-L in ay yihiin inta badan codsatay in fiiloyin looxa, laakiin qaar ka mid ah ka heli isticmaalka dhogor idaad iyo Xariir. Sida caadiga ah acetic acid lagu darayaa qubeyska dheeha si ay u caawiyaan qaadashada ee dheeha gal fiber ah. formaldehyde aasaasiga ah waxaa sidoo kale loo isticmaalaa in coloration ee warqadda.

macsarada formaldehyde

formaldehyde macsarada waa muhiimad beelaya in biyo iyo awoodi karin si toos ah dyeing macdantaa. Si kastaba ha ahaatee, hoos u khamriga cawaaqib xumadoodu waxay soo saartaa cusbada biraha alkali biyo-L dheeha. Foomkan waxaa inta badan ay leegyihiin, taasoo kiiska ah, waxaa loo yaqaan dheeha Leuco ah, oo uu leeyahay xidhiidh ah fiber dhar ah. dib u habaynta Xiga qayilo dheeha asalka ah beelaya. midabka ah ee denim waxaa sabab u ah indigo, dheeha macsarada asalka ah.

Direct formaldehyde

formaldehyde Direct waxaa caadi fuliyay qubeyska dheeh dhexdhexaad ah ama wax yar ka xumadoodu, ama meel u dhow karkaraya, dheeriga ah ee labada chloride sodium (NaCl) ama sodium sulfate (Na2SO4) ama carbonate sodium (Na2CO3). formaldehyde Direct waxaa loo isticmaalaa on suuf, warqad, maqaar, oo suufkayga, xariir iyo nylon. Waxaa sidoo kale loo isticmaalaa sida tilmaamayaasha pH iyo sida Wasaqda noolaha.

baaruud formaldehyde

formaldehyde baaruud waa formaldehyde jaban loo isticmaalaa in lagu dheeha suuf leh midabka madow. Dyeing dhibta ka kulaylinta dhar ah in xal of xarunta ah organic, sida caadiga ah derivative a nitrophenol, iyo tayadda ama polysulfide. xarunta organic sameynayso la il tayadda ah si ay u sameeyaan midabo madow in u hoggaansamaan dhar ah. Baaruud Black 1, dheeha ugu weyn ee lagu iibiyo by mugga, ma laha qaab kiimikada si fiican u qeexay.
