Starch ethers ndi gulu la mankhwala opangidwa kuchokera ku wowuma, polima wa carbohydrate opezeka m'magwero osiyanasiyana a mbewu monga chimanga, tirigu, ndi mbatata.Ma ether awa amagwiritsidwa ntchito kwambiri muzosindikiza za nsalu chifukwa cha mawonekedwe awo apadera komanso mapindu ambiri.M'munsimu muli ena mwaubwino waukulu wa starch ethers pakusindikiza kwa nsalu:

1. Katundu Wokhuthala: Ma etha wowuma amagwira ntchito ngati zokhuthala bwino pakusindikiza nsalu ndi kupanga.Iwo amawonjezera mamasukidwe akayendedwe a phala yosindikizira, yomwe imathandiza kulamulira kuyenda ndi kufalikira kwa utoto kapena pigment pamwamba pa nsalu.Kukhuthala koyenera ndikofunikira kuti muthe kujambula bwino komanso kumveka bwino komanso kulimba kwamtundu.
2. Tanthauzo Labwino Losindikizira: Ma ether owuma amathandizira kupanga zilembo zodziwika bwino pansalu poletsa kufalikira kapena kutulutsa magazi kwa utoto kapena utoto.Kukhuthala kwawo kumathandizira kuti mizere yosindikizidwa ikhale yakuthwa komanso yowoneka bwino, kumapangitsa kuti zonse zikhale bwino komanso zomveka bwino pamapangidwe osindikizidwa.
3. Mphamvu Yolowa Bwino: Ma starch ether amatha kupititsa patsogolo mphamvu yolowera ya phala losindikizira, kulola utoto kapena pigment kulowa molingana ndikuzama mu ulusi wansalu.Izi zimabweretsa zojambula zokhala ndi mtundu wabwino kwambiri, kukana kutsuka, komanso kulimba, popeza zopaka utoto zimamangirizidwa bwino ndi nsalu.
4. Kuchepetsa Zowonongeka Zosindikizira: Popereka kukhuthala kofanana ndi kulowa bwino, ma starch ether amathandizira kuchepetsa zolakwika zomwe zimasindikizidwa monga ma pinholes, streaking, ndi mottling.Izi zimapangitsa kuti zikhale zosavuta komanso zogwirizana ndi zofooka zochepa, kupititsa patsogolo maonekedwe onse ndi kukongola kwa nsalu yosindikizidwa.
5. Kugwirizana ndi Zingwe Zosiyanasiyana Zovala: Ma ethers owuma amawonetsa kuyanjana bwino ndi mitundu ingapo ya ulusi wa nsalu zachilengedwe komanso zopangidwa, kuphatikiza thonje, poliyesitala, silika, ndi rayon.Atha kugwiritsidwa ntchito posindikiza nsalu pamitundu yosiyanasiyana ya nsalu popanda kubweretsa zovuta pamtundu wa nsalu kapena magwiridwe antchito.
6. Kusamalira Chilengedwe: Ma starch ethers amachokera ku zomera zomwe zimatha kuwonjezedwanso ndipo amatha kuwonongeka, zomwe zimawapangitsa kukhala okonda zachilengedwe m'malo mwa zopangira zokhuthala komanso zomangira.Kugwiritsiridwa ntchito kwawo pakusindikiza nsalu kumathandiza kuchepetsa kukhudzidwa kwa chilengedwe cha njira zopangira nsalu, kugwirizanitsa ndi zolinga zokhazikika ndi malamulo.
7. Mtengo: Ma ethers owuma amapereka njira yotsika mtengo yosindikizira nsalu poyerekeza ndi zinthu zina zokhuthala kapena zowonjezera.Zimapezeka mosavuta pamsika pamitengo yopikisana ndipo zimatha kuphatikizidwa mosavuta m'mapangidwe osindikizira popanda ndalama zowonjezera.
8. Kusinthasintha Pakukonza: Ma ethers owuma amatha kusinthidwa kapena kuphatikizidwa ndi zowonjezera zina kuti zigwirizane ndi katundu wawo malinga ndi zofunikira zosindikiza.Opanga amatha kusintha kukhuthala, rheology, ndi mikhalidwe ina ya phala losindikiza posankha mitundu yoyenera ndi magiredi a ethers wowuma, kulola kusinthasintha ndikusintha mwamakonda muzosindikiza.

Mwachidule, ma ethers owuma amagwira ntchito yofunikira pakusindikiza kwa nsalu popereka makulidwe, kutanthauzira, kulowa, ndi zinthu zina zopindulitsa pakusindikiza phala ndi mapangidwe.Kugwiritsiridwa ntchito kwawo kumathandizira kupanga zojambula zapamwamba, zokhazikika, komanso zowoneka bwino pamagulu osiyanasiyana a nsalu pamene akupereka kukhazikika kwa chilengedwe ndi kutsika mtengo.
