Hydroxypropyl starch ether bakeng sa kaho

Hydroxypropyl Starch Ether (HPS) ke sehlahisoa sa starch se fetotsoeng se sebelisoang indastering ea kaho e le sekontiri, se kopanyang, le ho boloka metsi. HPS e entsoe ka ho phekola starch ea poone ka lihlopha tsa hydroxypropyl, e fanang ka thepa e ikhethang e e etsang hore e be molemo lits'ebetsong tse fapaneng tsa kaho.

E 'ngoe ea likopo tse ka sehloohong tsa HPS kahong ke ho ba motenya. HPS e na le mekhoa e metle ea ho tenya 'me e ka sebelisoa ho eketsa ponahalo ea lintho tse ekelitsoeng ke metsi, joalo ka pente, likhomaretsi le seretse. Viscosity ena e ntlafalitsoeng e ka thusa ho ntlafatsa ts'ebetso le ho ata ha lihlahisoa tsena, ho etsa hore ho be bonolo ho li sebelisa le ho li sebelisa.

HPS e boetse e sebelisoa e le se tlamang kahong. E ka thusa ho ntlafatsa matla a momahaneng a thepa, joalo ka seretse, likhomaretsi le li-grouts. Matla ana a ntlafetseng a momahano a ka thusa ho ntlafatsa ts'ebetso ea kakaretso ea lihlahisoa tsena, ho etsa hore li tšoarelle nako e telele le ho hanyetsa ho phunyeha, ho fokotseha, le mefuta e meng ea ho senyeha.

HPS e boetse e sebelisoa e le sesebelisoa sa ho boloka metsi kahong. E ka thusa ho ntlafatsa ho bolokoa ha metsi a lirekere, likhomaretsi le li-grouts, ho thusa ho ntlafatsa ts'ebetso ea tsona le ts'ebetso ka kakaretso. Ts'ebetso ena e ntlafetseng ea ho boloka metsi e ka boela ea thusa ho fokotsa kotsi ea ho petsoha le ho fokotseha, ho etsa hore lihlahisoa tsena li tšoarelle le ho tšepahala.

Qetellong, HPS ke motsoako o sebetsang ka mokhoa o fapaneng le o sebetsang indastering ea kaho. Bokhoni ba eona ba ho ntlafatsa viscosity, matla a momahano, le ho boloka metsi a thepa e fapaneng ea kaho e etsa hore e be karolo ea bohlokoa ntlafatsong ea lihlahisoa tsa kaho tsa boleng bo holimo le tse tšepahalang. Bonolo ba eona ba tšebeliso le litšenyehelo tsa eona li etsa hore e be khetho e tummeng mefuteng e mengata ea likopo, ho tloha mererong e menyenyane ea bolulo ho ea ho haha ​​​​mehaho e meholo ea khoebo.
