Dab tsi yog starch ether?

Starch ether yog daim ntawv hloov ntawm cov hmoov txhuv nplej siab, carbohydrate muab tau los ntawm cov nroj tsuag. Kev hloov kho tau muaj feem cuam tshuam rau cov txheej txheem tshuaj lom neeg uas hloov cov qauv ntawm cov hmoov txhuv nplej siab, ua rau cov khoom siv nrog kev txhim kho lossis hloov kho cov khoom. Cov hmoov txhuv nplej siab pom tias muaj kev siv thoob plaws hauv ntau cov ntawv thov kev lag luam vim lawv cov yam ntxwv tshwj xeeb. Qee hom kev siv tsiaj qus suav nrog hydroxyethyl starch (hes), hydroxypropps (hps), thiab carboxymethyl starch (CMS). Ntawm no yog qhov tseem ceeb ntawm cov hmoov txhuv nplej siab:

1. Tshuaj Kho Mob:

• Hydroxyethyl hmoov (hes): nyob rau hauv hes, hydroxyethyl pab pawg yog qhia rau cov hmoov txhuv nplej siab molecule. Qhov kev hloov pauv no tau txhim kho nws cov dej solubility thiab ua rau nws siv rau kev siv hauv cov tshuaj, uas muaj cov ntshav ntshav hloov kho, thiab hauv lwm cov ntawv thov.
• HydroxyPropyl Starch (HPS): HPS yog tsim los ntawm kev qhia txog cov pawg hydroxypropylropylrops. Qhov kev hloov kho no txhim kho cov khoom xws li cov dej solubility thiab ua yeeb yaj kiab ua ke, ua rau nws muaj kev lag luam xws li zaub mov, cov ntawv nyeem, thiab kev tsim kho.
• Carboxymethyl Starch (CMS): CMS yog tsim los ntawm kev qhia cov pab pawg carboxymethyl rau cov hmoov txhuv nplej siab lwg me. Qhov kev hloov kho tshiab uas cuam tshuam cov khoom xws li kev txuag dej, thickening, ua rau nws muaj txiaj ntsig zoo hauv kev siv cov nplaum, textiles, thiab tshuaj.

2. Dej Solubility:

• Starch cov neeg muaj kev pab cuam lwm tus neeg muaj kev ua kom muaj kev nthuav tawm cov dej solubility piv rau cov hmoov txhuv nplej siab ib txwm muaj. Qhov kev txhim kho solubility yog qhov zoo dua nyob rau hauv cov qauv uas nrawm dua qhov kev sib cuam tshuam nrawm lossis dispersion hauv dej yuav tsum tau ua.

3. Viscosity thiab thickening cov khoom:

• Starch cov neeg txawj ua haujlwm ua cov tuab tuab hauv ntau cov qauv. Lawv pab txhawb kom muaj viscosity ntau ntxiv, uas yog qhov tseem ceeb hauv kev siv xws li cov nplaum, thiab khoom noj khoom haus.

4. Zaj duab xis-tsim muaj peev xwm:

• Qee cov hmoov txhuv nplej siab, tshwj xeeb yog hydroxypropyl starch, pom zoo zaj duab xis-ua yeeb yaj kiab. Qhov no ua rau lawv haum rau cov ntawv thov uas kev tsim cov yeeb yaj kiab nyias, hloov tau yooj yim, xws li hauv cov zaub mov thiab tshuaj lag luam.

5. Txawb thiab cov khoom siv khi:

• Cov hmoov txhuv nplej siab tau siv los ua cov stabilizers thiab cov kev sib txuas ua ntau yam. Lawv pab txhim kho qhov ruaj khov ntawm emulsions thiab pab txhawb rau cohesiveness ntawm cov khoom lag luam zoo li cov ntsiav tshuaj zoo li cov ntsiav tshuaj.

6. Daim Ntawv Thov Tshaj Tawm:

• Cov hmoov txhuv nplej siab nrhiav kev siv cov nplaum, ob qho tib si hauv kev lag luam khoom noj khoom haus (piv txwv li cov pos hniav hloov) thiab tsis siv cov khoom noj khoom haus (piv txwv li cov ntawv nplaum).

7. Textile sizing:

• Hauv kev lag luam textile, cov neeg muaj kev paub ua cov hmoov txhuv nplej siab tau siv hauv txoj kev nyuaj los txhim kho lub zog thiab cov yarns thaum lub sijhawm xaws khaub ncaws.

8. Tshuaj Siv Tshuaj:

• Qee cov neeg muaj kev paub ua haujlwm STARS tau ua haujlwm hauv cov kws tshuaj. Piv txwv li, hydroxyethyl starch yog siv los ua cov ntshav hluav taws xob kom nthuav dav.

9. Kev tsim kho thiab cov ntaub ntawv hauv tsev:

• Starch neeg muaj kev paub, tshwj xeeb tshaj yog hydroxyprropyl starch thiab carboxymethyl hmoov, yog siv hauv kev sib xyaw ua ke sib xyaw. Lawv pab txhawb kom txhim kho adhesion, kev ua haujlwm, thiab dej rov qab.

10. Kev lag luam khoom noj:

11. Biodegradentab:

12. Kev txiav txim siab ib puag ncig:

Nws yog ib qho tseem ceeb kom nco ntsoov tias cov khoom tshwj xeeb thiab cov kev siv ntawm cov hmoov txhuv nplej siab tuaj yeem sib txawv raws li hom kev hloov kho thiab siv. Cov neeg tsim khoom siv cov ntaub ntawv ntxaws ntxaws qhia meej rau txhua tus ntawm Stars Etheting kev xaiv ntau yam rau lawv cov ntawv thov tshwj xeeb.
