Hoʻokaʻawale ʻana o ka hoʻoluʻu ʻana

Hoʻokaʻawale ʻana o ka hoʻoluʻu ʻana

Wahi a nā pūʻulu reactive like ʻole, hiki ke hoʻokaʻawale ʻia nā mea hoʻonaninani i ʻelua ʻano: symmetrical triazene type a me vinylsulfone type.

ʻAno triazene Symmetric: Ma kēia ʻano o nā mea hoʻoula hou, ʻoi aku ka ikaika o nā waiwai kemika o nā ʻātoma chlorine ikaika.I ka wā o ke kala ʻana, ua hoʻololi ʻia nā ʻātoma chlorine e nā fiber cellulose i loko o ke ʻano alkaline a lilo i hui haʻalele.ʻO ka pane ʻana ma waena o ka waiʻona a me ka fiber cellulose, he bimolecular nucleophilic substitution reaction.

ʻAno Vinyl sulfone: vinyl sulfone (D-SO2CH = CH2) a i ʻole β-hydroxyethyl sulfone sulfate.I loko o ke kaʻina hana hoʻoluʻu, β-hydroxyethyl sulfone sulfate e hoʻoheheʻe ʻia i loko o kahi ʻano alkaline e hana i kahi hui vinyl sulfone.Hoʻohui ka hui vinyl sulfone me ka fiber cellulose e hana i kahi pane hoʻohui nucleophilic e hana i kahi paʻa covalent.

ʻO nā mea hoʻonaninani ʻelua i ʻōlelo ʻia ma luna nei, ʻo ia nā ʻano nui o nā pelo reactive me ka nui loa o ka huahana ma ka honua.I mea e hoʻomaikaʻi ai i ka helu hoʻopaʻa ʻana o nā mea hoʻoheheʻe reactive, ua hoʻokomo ʻia ʻelua mau pūʻulu reactive i loko o ka mole kala i nā makahiki i hala iho nei, ʻo ia hoʻi nā mea pena ʻelua.

Hiki ke hoʻokaʻawale ʻia nā dyes reactive i kekahi mau pūʻulu e like me kā lākou mau pūʻulu reactive ʻokoʻa:

1. ʻO ka X-type reactive dye i loko o ka dichloro-s-triazine reactive hui, he mea haʻahaʻa haʻahaʻa haʻahaʻa, kūpono no ke kala ʻana i ka fiber cellulose ma 40-50 ℃.

2. Aia i loko o ka hui K-type reactive dye ka monochlorotriazine reactive, he mea ho'olu'u wela ki'eki'e, kūpono no ka pa'i 'ana a me ka waiho 'ana i nā lole pulupulu.

3. Aia i loko o nā mea ho'onanea 'ano KN nā pū'ulu ho'ohenehene o ka hydroxyethyl sulfone sulfate, 'o ia nā mea ho'onā wela waena.ʻO 40-60 ℃ ka mahana hoʻoluʻu, kūpono no ka hoʻoluli ʻana i ka pulupulu, ka wai anuanu, a me ka paʻi ʻana i ke kala e like me ke kala hope;kūpono hoʻi no ke kala ʻana i nā lole hemp.

4. Aia i loko o ka M-type reactive dye nā pū'ulu ho'opi'i pālua a no ka wai ho'onā wela waena.ʻO 60°C ka mahana o ke kala.He kūpono ia no ka paʻi ʻana i ka mahana wela a me ke kala ʻana i ka pulupulu a me ke olonā.

5. Loaʻa i nā mea hoʻoluʻu ʻano ʻano KE ʻano hui pālua a pili i nā mea hoʻonaninani wela kiʻekiʻe, kūpono ia no ka hoʻoluli ʻana i ka pulupulu a me nā lole olonā.

Nā hiʻohiʻona

1. Hiki ke hoʻopili ke kala me ka fiber e hana i kahi paʻa covalent.Ma lalo o nā kūlana maʻamau, ʻaʻole e hoʻokaʻawale ʻia kēia hui ʻana, no laila ke hoʻoluu ʻia ka mea hoʻonaninani reactive ma ka fiber, e loaʻa iā ia ka wikiwiki o ka waihoʻoluʻu maikaʻi, ʻoi aku ka mālama ʻana i ka pulu.Eia kekahi, ʻaʻole e palupalu ka fiber e like me kekahi mau wai waihoʻoluʻu ma hope o ke kala ʻana.

2. Loaʻa iā ia ka hana hoʻohālikelike maikaʻi, nā waihoʻoluʻu ʻoniʻoni, ʻālohilohi maikaʻi, maʻalahi e hoʻohana, chromatogram piha, a me nā kumu kūʻai haʻahaʻa.

3. Hiki ke hana nui ia ma Kina, hiki ke hoopiha piha i na pono o ka oihana pa'i a me ke kala;he ākea ka hoʻohana ʻana, ʻaʻole wale no ke kala ʻana i nā fiber cellulose, akā no ke kala ʻana i nā fiber protein a me kekahi mau lole i hui ʻia.

ʻO mākou nā mea kūʻai mai Reactive Dyes.Inā makemake ʻoe i kā mākou huahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
