Hydroxypropyl starch ether-HPS

Nhanganyaya yeStarch

Starch ndeimwe yeakanyanya kuwanda makabhohaidhiretsi anowanikwa mune zvakasikwa uye anoshanda seyokutanga simba sosi yezvipenyu zvakawanda, kusanganisira vanhu. Inoumbwa nemayuniti eglucose akabatanidzwa pamwechete mumaketani marefu, achigadzira amylose uye amylopectin mamorekuru. Aya mamorekuru anowanzo kutorwa kubva muzvirimwa zvakaita sechibage, gorosi, mbatatisi, uye mupunga.

Starch Kugadziriswa

Kuti iwedzere zvimiro zvayo uye kuwedzera mashandisirwo ayo, starch inogona kuita akasiyana makemikari shanduko. Kumwe kugadziridzwa kwakadaro ndiko kuunzwa kwemapoka ehydroxypropyl, zvichikonzera hydroxypropyl starch ether (HPS). Uku kugadziridzwa kunoshandura hunhu hwenyama uye makemikari e starch, ichiita kuti ive yakawanda uye inokodzera kuwanda kwekushandiswa kwemaindasitiri.

Kemikari Mamiriro uye Zvivakwa

Hydroxypropyl starch etherinotorwa kubva ku starch kuburikidza nekuita kwemakemikari kunosanganisira kutsiva mapoka ehydroxyl nemapoka ehydroxypropyl. Iyi nzira inounza hydrophobic padivi cheni pane iyo starch molecule, ichipa iyo nekuvandudzwa kwemvura kuramba uye kugadzikana. Iyo dhigirii yekutsiva (DS) inoreva huwandu hwemapoka ehydroxypropyl akawedzerwa paglucose unit uye anokanganisa zvakanyanya zvimiro zveHPS.

Zvishandiso zveHydroxypropyl Starch Ether

Indasitiri Yekuvaka: HPS inowanzoshandiswa seyakakora mumiriri, binder, uye inodzikamisa mukuvaka zvinhu zvakaita sedhaka, plaster, uye grout. Kugona kwayo kuvandudza kushanda, kunamatira, uye kuchengetedza mvura kunoita kuti ive yekuwedzera yakakosha mukuumbwa kwekuvaka.

Indasitiri yeChikafu: Muindasitiri yechikafu, HPS inowana maapplication muzvigadzirwa zvakaita sesosi, madhirezi, uye zvinhu zvekubheka. Inoshanda seyakakora, inosimbisa, uye texturizer, inosimudzira manyorerwo, muromo, uye hupenyu hwesherufu hwezvigadzirwa zvekudya. Uyezve, HPS inowanzofarirwa pamusoro pezvimwe zvakabva sitachi nekuda kwekupisa kwayo kwakanyanya uye kugadzikana kwekugera.

Pharmaceuticals: Mishonga yemishonga inoshandisa HPS sebhainda mukugadzira piritsi, uko inovandudza kuparara kwehwendefa uye kuparara kwemazinga. Pamusoro pezvo, inoshanda senge firimu-inogadzira mumiriri mukuputira maapplication, ichipa mahwendefa ane inodzivirira uye inoyevedza yekunze layer.

Personal Care Zvigadzirwa: HPS chinhu chakajairika muzvigadzirwa zvekuchengeta zvemunhu senge shampoos, maconditioner, uye makirimu. Inoshanda seyakakora uye kudzikamisa, inosimudzira kuenderana kwechigadzirwa, magadzirirwo, uye kugadzikana kwesherufu. Uyezve, HPS inopa magadzirirwo ezvivakwa kune bvudzi uye ganda rekuchengetedza maumbirwo, zvichibatsira mukuita kwavo kwese.

Indasitiri yePepa: Mukugadzira mapepa, HPS inoshandiswa seyepamusoro saizi mumiriri kuvandudza simba remapepa, kutsvedza kwepamusoro, uye kudhinda. Mafirimu ayo ekugadzira firimu anogadzira jira rakafanana papepa, zvichiita kuti inki iwedzere kunamatira uye kuderedza kunyura kweinki.

Indasitiri yeMachira: HPS inoshanda seye saizi muindasitiri yemachira, kwainoiswa kune shinda uye machira kuvandudza maitiro avo ekubata panguva yekuruka kana kuruka maitiro. Pamusoro pezvo, inopa kuomarara uye kusimba kumafayibha, ichifambisa kudzika kwemvura kugadzirisa uye kuwedzera kunaka kwezvakapedzwa zvigadzirwa zvemachira.

Oiri Drilling Fluids: HPS inoshandiswa muindasitiri yeoiri negasi seviscosifier uye fluid-kurasikirwa inodzora mumiriri mumvura yekuchera. Inobatsira kuchengetedza viscosity yedhaka rekuchera, inodzivirira kurasikirwa kwemvura mukugadzirwa, uye inodzikamisa madziro emutsime, nekudaro inogonesa mashandiro ekuchera uye kuve nechokwadi chekuvimbika.

Hydroxypropyl starch ether (HPS)inosiyana-siyana starch kubva kune yakapararira maapplication mumaindasitiri akasiyana siyana. Musanganiswa wayo wakasarudzika wezvivakwa, zvinosanganisira kukora, kusunga, kudzikamisa, uye kugona kugadzira firimu, kunoita kuti ive yakakosha mukuumbwa kubva pakuvaka kusvika kune zvigadzirwa zvekudya. Sezvo kudiwa kwezvinowedzera uye eco-hushamwari zvekuwedzera zviri kuramba zvichikura, HPS inomira pachena seimwe nzira inogona kudzokororwa uye biodegradable kune ekugadzira mapolymers, ichiwedzera kusimbisa chinzvimbo chayo sechinhu chakakosha mukushandisa kwakawanda kwemaindasitiri nevatengi.
