Hydroxypropyl starch ether-hps

Taw qhia rau cov hmoov txhuv nplej siab

Cov hmoov txhuv nplej siab yog ib qho ntawm cov carbohydrates ntau tshaj plaws pom nyob rau hauv qhov thiab pabcuam ua tus thawj lub zog rau ntau tus kab mob muaj sia, suav nrog tib neeg muaj sia. Nws yog tsim cov chav dej qab zib txuas ua ke sib txuas ua ke hauv cov saw ntev, tsim cov amylose thiab amylopectin molecules. Cov lwg me me no feem ntau muab rho tawm los ntawm cov nroj tsuag xws li pob kws, nplej, qos, thiab mov.

Starch Hloov Kho

Txhawm rau txhim kho nws cov khoom thiab nthuav nws cov ntawv thov, cov hmoov txhuv nplej siab tuaj yeem ua ntau yam kev hloov kho cov tshuaj lom neeg. Ib qho kev hloov kho tshiab yog kev qhia txog cov pab pawg hydroxypropyl, uas ua rau hydroxyproppyl starch ether (hps). Qhov kev hloov kho no ntawm lub cev thiab cov tshuaj lom neeg ntawm cov hmoov txhuv nplej siab, ua rau nws ntau yam thiab haum rau ntau yam kev lag luam siv.

Cov qauv tshuaj thiab cov khoom

HydroxyPropyl Starch etheryog muab los ntawm cov hmoov txhuv nplej siab los ntawm kev siv tshuaj lom neeg uas cuam tshuam nrog cov pab pawg ntawm hydroxyl nrog Hydroxypropyropsyl pawg. Tus txheej txheem no qhia txog hydrophobic sab chains mus rau cov hmoov txhuv nplej siab Molecule, muab nws nrog cov dej tsis kam ua tsis kam thiab ruaj khov. Cov qib degree (DS) yog hais txog pes tsawg tus neeg hydroxypropropal ntxiv ib chav dej qab zib thiab ntau cov khoom ntawm HPS.

Cov ntawv thov ntawm hydroxypropyl starch ether

Kev tsim kho kev tsim kho: HPS feem ntau siv los ua tus neeg sawv cev tuab, binder, thiab stabilizer, thiab stabilizer nyob rau hauv cov kab cug, plaster, thiab grout. Nws muaj peev xwm txhim kho kev ua haujlwm, adhesion, thiab dej rov qab ua rau nws muaj txiaj ntsig ntxiv hauv kev tsim qauv.

Kev lag luam khoom noj khoom haus: hauv kev lag luam khoom noj khoom haus, HPS nrhiav cov ntawv thov hauv cov khoom lag luam xws li cov kua nplaum, cov khoom hnav, thiab bakery. Nws ua haujlwm raws li tuab, stabilizer, thiab texturizer, txhim kho cov kev ntxhib los mos, ua lub neej ntawm cov khoom noj. Ntxiv mus, HPS feem ntau nyiam dua lwm cov hmoov txhuv nplej siab vim nws cov cua sov zoo heev thiab shear stability.

Kws Tshuaj: Cov Tshuaj Siv Tshuaj Siv HPS raws li Binder hauv ntsiav tshuaj tsim, qhov twg nws txhim kho cov ntsiav tshuaj ua kom tsis sib xws thiab tus nqi sib cais. Ib qho ntxiv, nws ua haujlwm ua zaj duab xis-ua tus neeg sawv cev hauv cov ntawv thov txheej, muab cov ntsiav tshuaj nrog kev tiv thaiv thiab ua kom zoo nkauj ntxig txheej.

Cov khoom lag luam ntawm tus kheej: HP yog ib qho khoom siv uas nquag muaj nyob rau hauv cov khoom lag luam saib xyuas ntawm tus kheej xws li tshuaj zawv plaub hau, cov khoom noj kom zoo nkauj, thiab cov tshuaj ntsuab. Nws ua haujlwm raws li tuab thiab stabilizer thiab stabilizer, txhim kho cov khoom lag luam, kev ntxhib los mos, thiab muab txav ruaj ruaj. Tsis tas li, HPS tshem tawm cov khoom siv rau cov plaub hau thiab kev tu tawv nqaij, ua rau lawv cov kev ua tau zoo tag nrho.

Kev lag luam ntawv: hauv cov ntawv tsim khoom, HPS tab tom siv los ua tus neeg sawv cev saum ntuj los txhim kho daim ntawv lub zog, nto du, thiab tshuab luam ntawv. Nws cov duab ua yeeb yaj kiab tsim cov txheej txheej ua ke ntawm daim ntawv saum npoo av, ua rau enhanced ink adhesion thiab txo qis ink nqus.

Textile kev lag luam: HPs ua hauj lwm ua tus sawv cev ntawm kev lag luam textile, qhov twg nws tau thov rau cov tsiaj thiab cov ntaub ua haujlwm los txhim kho cov yam ntxwv ntawm nws lossis cov txheej txheem knitting. Ib qho ntxiv, nws imparts txhav thiab lub zog rau cov fibers, txhawb nqa cov khoom lag luam hauv qab thiab txhim kho cov khoom lag luam tiav.

Roj Drilling kua: HPS ua hauj lwm hauv cov roj thiab roj kev lag luam raws li cov viscosifier thiab fluid-poob tswj tus neeg sawv cev hauv drilling. Nws pab tswj cov viscosity ntawm cov av nkos, tiv thaiv kom tsis txhob muaj dej, thiab muaj phab ntsa zoo nkauj, yog li ua kom haum kev siv drilling thiab ua kom muaj kev ncaj ncees.

HydroxyPropyl Starch Ethere (HPS)yog ib tug ntau starch derivative nrog kev siv thoob plaws thoob plaws ntau yam kev lag luam. Nws tshwj xeeb ua ke ntawm cov khoom, suav nrog cov thickening, khi, ruaj khov, thiab zaj duab xis-ua rau cov khoom siv rau kev tsim kho rau cov khoom noj. Raws li qhov kev thov rau kev nyab xeeb thiab eco-phooj ywg ntxiv txuas ntxiv mus rau cov hluavtaws tshiab rau cov khoom siv hluav taws xob ntxiv thiab biodegradable nws txoj haujlwm ua cov khoom siv tseem ceeb hauv ntau cov ntawv thov.
