Hydroxypropyl starch ether (HPS) is a modified starch derivative ine hydroxypropyl mapoka akabatanidzwa kumusana westarch. Iyo inoratidza akati wandei maitiro ekushandisa anoita kuti ive yakakodzera kune akasiyana maindasitiri uye ekutengesa maapplication. Heano mamwe eakakosha ekushandisa maitiro ehydroxypropyl starch ether:

1. Kuchengetedzwa Kwemvura: HPStE inoshanda zvakanyanya mukuchengetedza mvura mukuumbwa nekuda kweiyo hydrophilic chimiro. Ichi chivakwa chinonyanya kubatsira mukuvaka senge simende dhaka, renders, uye plasters, uko kuchengetwa kwemvura kunobatsira kuvandudza kushanda, hydration, uye kurapa kwezvinhu.
2. Kukora: HPStE inoshanda seyakagwinya gobvu mumiriri mune aqueous masisitimu, ichiwedzera viscosity uye kuenderana kwekuumbwa. Ichi chivakwa chinoshandiswa mumashandisirwo akadai seanonamira, pendi, uye machira, uko kukobvu kunodiwa kuti uwane inodiwa kuyerera zvivakwa uye kuumbwa kwemafirimu.
3. Kugadzira Firimu: HPStE inogona kugadzira mafirimu akajeka uye anoshanduka kana akaparadzirwa mumvura. Hunhu uhwu hwakakosha mumashandisirwo akadai semabhanditi, zvinonamira, uye zvisimbiso, uko kuumbwa kwemafirimu kwakakosha pakupa zvipingamupinyi zvekudzivirira, nzvimbo dzekubatanidza, kana kuvhara majoini.
4. Kudzikamisa: HPStE inoratidza kugadzikana kwakanakisa mumasisitimu ane aqueous, kudzivirira kuparadzaniswa kwechikamu, sedimentation, kana coagulation yezvimedu. Iyi pfuma yekudzikamisa inobatsira mukugadzira senge emulsions, suspensions, uye dispersions, uko kuchengetedza kufanana uye kugadzikana kwakakosha pakuita kwechigadzirwa uye hupenyu hwesherufu.
5. Yakavandudzwa Kunamatira: HPStE inosimudzira adhesion zvivakwa mumhando dzakasiyana siyana nekusimudzira kudyidzana pakati penzvimbo uye mabhaidha. Hunhu uhu hunobatsira mune zvinonamira, zvisimbiso, uye machira, uko kunamatira kwakasimba kune substrates kwakakosha pakubatanidza, kuvhara, kana kuchengetedza nzvimbo.
6. Kugarisana: HPStE inopindirana nehuwandu hwakawanda hwezvimwe zvinowedzera, mapolima, uye zvimisikidzo zvinowanzoshandiswa mukugadzira. Uku kuwirirana kunobvumira kushandiswa kwakasiyana-siyana uye magadzirirwo akarongedzerwa kune zvakati zvinodiwa uye maitiro ekuita.
7. pH Kugadzikana: HPStE inoratidza kugadzikana kwakanaka pamusoro pehupamhi pH renji, ichiita kuti ive yakakodzera kushandiswa mune acidic, kwayakarerekera, uye alkaline maumbirwo. Hunhu uhwu hunokwidziridza kuita kwayo uye kushanda kwayo mumaindasitiri akasiyana siyana, anosanganisira ezvekudya, emishonga, kutarisirwa kwevanhu, uye kuvaka.
8. Biodegradability: HPStE inotorwa kubva kune yakasikwa sitachi masosi uye inoodza, ichiita kuti ive nehushamwari uye inochengetedza. Hunhu uhwu hunoenderana nekukura kuri kudiwa kwezvinhu zveeco-hushamwari mumaindasitiri akasiyana siyana uye maapplication.

Pakazere, maitiro ekushandisa ehydroxypropyl starch ether anoita kuti ive yekuwedzera yakakosha mune dzakasiyana siyana dzekugadzira uye maindasitiri, anosanganisira kuvaka, anonamira, machira, machira, mishonga, uye zvigadzirwa zvekuchengeta munhu. Kuita kwayo kwakasiyana-siyana, kuita, uye kusimba kunopa mukushandiswa kwayo kwakapararira uye kugamuchirwa mumashandisirwo akasiyana siyana.
