Senge multifunctional kemikari raw material,sulfamic acidinoita basa rakakosha muindasitiri yedhayi. Iyo yakasarudzika yemakemikari zvimiro inoita kuti ishandiswe zvakanyanya mukugadzira dhayi uye maitiro ekudhaya. Iyo haigone kungoshandiswa sechinhu chinobatsira kuvandudza mashandiro edhayi synthesis, asi zvakare inogona kushandiswa kugadzirisa iyo pH kukosha kweiyo dhayi maitiro kukwidziridza kutora kwedhayi uye kukurumidza kwemavara. Ichi chinyorwa chinoongorora mabasa akakosha anoita sulfamic acid mukugadzira dhayi uye mabhenefiti ayo kuindasitiri.
1.Kubvisa nitrite yakawandisa
Mukugadzira dhayi, diazotization reaction inhanho yakakosha mukugadzirwa kweazo dhayi. Kuita kunowanzoshandisa sodium nitrite uye hydrochloric acid kugadzira nitrous acid, iyo inopindirana nemaamine anonhuhwirira kuita diazonium munyu. Zvisinei, kana nitrite yakawandisa ikasabatwa nenguva, inokonzera kusvibiswa kwezvakatipoteredza, uye nitrite yakawandisa inogona kuita nemamorekuru edhayi, inokanganisa ruvara uye kugadzikana kwedhayi. Naizvozvo, aminosulfonic acid inoshandiswa zvakanyanya muindasitiri yedhayi seyakanaka uye yakachengeteka nitrite inobvisa. The reaction principle ndeiyi inotevera:
NaNO₂ + H₃NSO₃ → N₂ + NaHSO₄ + H₂O
Aminosulfonic acidinopindura nekukurumidza ne nitrite uye inogona kunyatso shandura yakawandisa nitrite kuita isingakuvadze nitrogen gasi.
- Specific applications
Mushure mekurapa kwediazotization reaction: Mushure mekuita diazotization kwapera, wedzera huwandu hwakakodzera hweaminosulfonic acid solution uye simbisa maitiro kwenguva yakati kuti ubvise zvachose nitrite yakawandisa.
Kucheneswa kwedhayi kwepakati: Mugadziriro yedhayi yepakati, aminosulfonic acid inogona kushandiswa kubvisa yakasara nitrite uye kugadzirisa kuchena kwechigadzirwa.
Kugadziriswa kwemvura yetsvina: Kune dhayi tsvina ine nitrite, aminosulfonic acid inogona kushandiswa pakurapa kudzikisa huwandu hwe nitrite mumvura yetsvina uye kuderedza kusvibiswa kune zvakatipoteredza.
2. Kugadzikana kweDye Solutions
Muindasitiri yedhayi, kugadzikana kwezvigadziriso zvedhayi kwakakosha pakuona yunifomu uye inopindirana ruvara. Sulfamic acid inoshanda seyakagadzika mumiririri, kudzivirira nguva isati yakwana hydrolysis uye kushatisa kwemamorekuru edhayi panguva yekuchengetera nekushandisa. Ichi chimiro chinonyanya kukosha mumadhayi anogadzirisa, apo kuchengetedza kutendeseka kwemakemikari kunokosha pakuwana mavara ane simba uye anogara kwenguva refu.
3. pH Kudzora
Kubudirira kwedhayi dzakawanda kunoenderana nekuchengetedza chaiyo pH level. Sulfamic acid, inozivikanwa nekunyorova kwayo acidity, inoshanda senge pH inogadzirisa mumabhati edhayi. Nekunyatso kudzora iyo pH, inova nechokwadi chemamiriro akakwana ekugadzirisa dhayi pamafibers, ichiwedzera kugona kwedhayi uye kuderedza njodzi yekusaenzana kwemavara kana kuremara.
4. Descaling uye Kuchenesa Dhayi Equipment
Kugadzirwa kwedhayi uye kushandiswa kunowanzo tungamira mukuunganidzwa kwechiyero uye zvakasara mumidziyo. Sulfamic acid ine simba rekudzikisa zvivakwa inoita kuti ive yakanakisa yekuchenesa mumiriri wekubvisa aya madhipoziti pasina kukuvadza muchina. Kugara kucheneswa ne sulfamic acid hakungonatsiridza hupenyu hwemidziyo chete asi zvakare kunovimbisa kuti nzira yekudhaya inoramba isina kusvibiswa, zvichikonzera zvigadzirwa zvemhando yepamusoro.
5. Kuvandudza Kudhaya Hunhu paFibers
Sulfamic acid inosimudzira kupinda nekugadzirisa dhayi pamafibers akadai sedonje, makushe, uye zvekugadzira zvinhu. Nekugadzira nharaunda ine acidic yakakodzera, inova nechokwadi chekunyura uye kubatana kwemamorekuru edhayi kune fiber, zvichitungamira kune mamwe mavara ane simba uye akasimba. Izvi zvinonyanya kubatsira mumaindasitiri emachira anoda zvemhando yepamusoro kupera.
Basa reSulfamic acid muindasitiri yedhayi rakasiyana-siyana, richibva mukudzikamisa zvigadziriso zvedhayi kusvika pakuvandudza kunaka kwedhayi, michina yekuchenesa, uye kuchenesa mvura. Hunhu hwayo hwakasiyana uye hushamwari hwezvakatipoteredza hunoita kuti ive chinhu chakakosha chevagadziri vanotsvaga kugona uye kusimba.
