Ether wothira (wotchedwanso mafuta odzola a polymer)

Ma ether a starch, omwe amadziwikanso kuti mafuta a polymer, ndi ofunikira kwambiri m'mafakitale ambiri. Ndi mtundu wa ma polima osakhala a ionic, osungunuka m'madzi okhala ndi ntchito zosiyanasiyana komanso mafuta abwino kwambiri. Ether ya starch imatha kupezeka kuchokera kuzinthu zosiyanasiyana, monga chimanga, tirigu, tapioca, mbatata, mpunga, ndi mbewu zina.

Kawirikawiri, ma Starch Ether amagwiritsidwa ntchito kupititsa patsogolo magwiridwe antchito a zinthu zosiyanasiyana mwa kuchepetsa kukangana ndikuwongolera kayendedwe ka madzi. Amagwiritsidwa ntchito kwambiri popanga mapepala, nsalu, zomatira, ma polima, sopo ndi zinthu zosamalira thupi. Mu pepalali, tifufuza za makhalidwe, ntchito, ndi ubwino wa ma Starch Ether, omwe amadziwikanso kuti mafuta odzola a polima.

Katundu wa Starch Ether.

Ma ether a starch ndi mtundu wa carbohydrate polymer womwe, chifukwa cha kapangidwe kake ka mankhwala, uli ndi mphamvu zabwino kwambiri zopaka mafuta. ​Amakhala ndi unyolo wa mamolekyu a shuga omwe amagwirizanitsidwa pamodzi ndi ma glycosidic bonds. Kapangidwe kameneka kamawapangitsa kukhala osungunuka m'madzi, ndipo amasungunuka mosavuta m'mitundu yosiyanasiyana ya zosungunulira monga madzi, ethanol, ndi methanol.

Ma ether a starch amatha kusinthidwa pogwiritsa ntchito njira zosiyanasiyana monga acid hydrolysis, oxidation, ndi esterification kuti apange zinthu zomwe zimakhala ndi mawonekedwe apadera. Ma ether a starch osinthidwa omwe amagwiritsidwa ntchito kwambiri ngati mafuta a polymer ndi awa: Hydroxypropyl starch ether, Carboxymethyl starch ether, ndi Hydroxyethyl starch ether.

Ntchito za Starch Ethers

Makampani Opanga Mapepala: Ma starch ether amagwiritsidwa ntchito kwambiri m'makampani opanga mapepala ngati zinthu zoyezera kukula kwa pamwamba, zinthu zomangira mkati, komanso zowonjezera zonyowa. Zimathandiza kukonza mphamvu, kusalala, ndi kuyera kwa pepala, kuchepetsa fumbi la pepala, komanso kukonza kumatirira kwa inki.

Makampani Opanga Nsalu: Mu makampani opanga nsalu, Starch Ether imagwiritsidwa ntchito ngati chowonjezera kukula kwa nsalu kuti iwonjezere mphamvu, kusinthasintha, komanso kuuma. Amagwiritsidwanso ntchito ngati zomaliza kuti awonjezere kufewa ndi mawonekedwe a nsalu.

Makampani Opangira Zomatira: Starch ether imagwiritsidwa ntchito mumakampani opanga zomatira ngati chothira, chomangira, komanso chotulutsa zinthu zomatira. Zimathandiza kukonza kayendedwe ka zomatira, kuwonjezera kukhuthala kwake, komanso kumamatira kwake ku zinthu zosiyanasiyana.

Ma polima: Ma ether a starch amagwiritsidwa ntchito ngati ma emulsifier, stabilizers ndi thickeners popanga ma polima osiyanasiyana. Amathandiza kukonza kufalikira kwa ma polima motero amawonjezera mphamvu zawo monga kuuma, mphamvu yokoka komanso kusinthasintha.

Makampani Opanga Zotsukira: Ma ether a starch amagwiritsidwa ntchito mumakampani opanga zotsukira ngati zinthu zokhuthala komanso zosakaniza. Amathandiza kuwonjezera kukhuthala ndi kukhazikika kwa zotsukira, kukulitsa mphamvu zawo zotsukira komanso kusungunuka bwino.

Zosamalira Munthu: Starch Ether imagwiritsidwa ntchito mu zosamalira munthu monga shampu, mafuta odzola ndi mafuta odzola monga chowonjezera kukhuthala, emulsifier ndi stabilizer. Zimathandiza kukonza kukhuthala ndi kukhazikika kwa chinthucho, kuwonjezera fungo lake, komanso kuwonjezera nthawi yake yosungiramo zinthu.

Ubwino wogwiritsa ntchito Starch Ethers

- Zowola: Ma Ether a Starch amatha kuwola, zomwe zikutanthauza kuti sawononga chilengedwe.. Amatha kusweka mosavuta ndi tizilombo toyambitsa matenda, zomwe zimachepetsa mphamvu yawo pa chilengedwe.

- Yongowonjezedwanso: Ma Ether a sitachi amachokera ku zinthu zongowonjezedwanso monga chimanga ndi tirigu, zomwe zimapangitsa kuti akhale gwero lokhazikika la mafuta odzola.

- Zachuma: Ma Ether a Starch ndi otsika mtengo poyerekeza ndi mafuta opangidwa, zomwe zimapangitsa kuti akhale njira yotsika mtengo kwa opanga.

- Osakhala ndi poizoni: Ma Ether a Starch si oopsa, zomwe zimapangitsa kuti akhale otetezeka kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Sali pachiwopsezo chilichonse pa thanzi la anthu kapena nyama.

Ma ether a starch, omwe amadziwikanso kuti mafuta a polymer, ndi ofunikira kwambiri m'mafakitale osiyanasiyana chifukwa cha mphamvu zawo zabwino zodzola. Amachokera ku zinthu zongowonjezedwanso, zowola, zopanda poizoni komanso zotsika mtengo, zomwe zimapangitsa kuti zikhale njira zabwino kwambiri m'malo mwa mafuta opangidwa. Opanga amagwiritsa ntchito Ma ether a Starch popanga zinthu zosiyanasiyana monga mapepala, nsalu, zomatira, ma polima, sopo ndi zinthu zosamalira thupi kuti awonjezere magwiridwe antchito awo, kuchepetsa kukangana ndikuwongolera kayendedwe ka madzi.
