Kedu ihe bụ hydroxypropyl starch maka ngwa agha?

Hydroxypropyl starch maka ngwa agha bụ ihe amịpụtara starch emezigharịrị nke a na-ejikarị dị ka mgbakwunye n'ụdị ngwa ngwa sitere na ciment.A na-emezi ụdị starch a na kemịkalụ ka ọ tinye otu hydroxypropyl, nke na-eme ka arụmọrụ ya na ọrụ ya dị na ngwa ngwa ngwa.Hydroxypropyl starch na-enye aka na akụrụngwa dị iche iche na ngwa agha, na-eme ka arụ ọrụ dịkwuo mma, nrapado, na njide mmiri.

Nke a bụ ụfọdụ njirimara na ojiji nke stachi hydroxypropyl maka ngwa agha:

Njirimara:

1. Mmiri Solubility:
-Hydroxypropyl starch na-abụkarị mmiri soluble, na-enye ohere maka mfe ntinye n'ime ngwa agha formulations.

2. Nhazi agbanweela:
- Ngbanwe hydroxypropyl gụnyere iwebata otu hydroxypropyl na molekul starch, na-agbanwe nhazi ya.

3. Ngwongwo na-eme ka o sie ike:
- Hydroxypropyl starch na-arụ ọrụ dị ka ihe na-eme ka mmiri sie ike, na-emetụta viscosity ya ma na-enye aka na nkwụsi ike nke nhazi ahụ.

4. Mgbakwunye mma:
- Mgbakwunye nke hydroxypropyl starch na-eme ka njirimara adhesion nke ngwa agha dịkwuo mma, na-eduga na njikọ dị mma na mkpụrụ.

5. Njide mmiri:
- Hydroxypropyl starch na-enyere aka na njigide mmiri n'ime ngwa agha ahụ, na-egbochi ihicha oke ma na-eme ka ọrụ nke ihe dịkwuo mma.

A na-eji na Mortar:

1. Mmelite arụ ọrụ:
- Hydroxypropyl starch na-eme ka arụ ọrụ nke ngwa agha dịkwuo mma site na-emetụta njirimara rheological ya.Nke a bara uru karịsịa na ngwa dị ka plasta na nsụgharị.

2. Mmelite adhesion:
- Na tile adhesives na ngwa ngwa ndị ọzọ, hydroxypropyl starch na-eme ka adhesion dịkwuo mma, na-akwalite njikọ dị mma n'etiti ngwa agha na mkpụrụ.

3. Njide mmiri:
- Njirimara mmiri nke hydroxypropyl starch dị mkpa na ngwa ngwa ngwa.Ha na-enyere aka igbochi ngwa ngwa ihicha ngwa ngwa, na-enye ohere maka ogologo oge ọrụ na ọgwụgwọ ka mma.

4. Mbelata mbelata:
- Hydroxypropyl starch na-enye aka na mbelata sagging na ngwa kwụ ọtọ, dị ka mgbe ị na-etinye ngwa agha na mgbidi.Nke a na-enyere aka ịnọgide na-enwe oke na ịdị n'otu achọrọ.

5. Nkwekọrịta emelitere:
- Ngwongwo siri ike nke hydroxypropyl starch na-enye aka na nhazi na udidi nke ngwa agha ahụ, na-eme ka ọ dị mfe ijikwa na itinye.

Ọ dị mkpa iburu n'obi na arụmọrụ a kapịrị ọnụ nke stachi hydroxypropyl na ngwa ngwa ngwa nwere ike ịdabere n'ihe ndị dị ka ịdị arọ ya, ogo nke nnọchi ya, na nhazi nke ngwa agha ahụ.Ndị na-emepụta ihe na-enyekarị ụkpụrụ nduzi na akwụkwọ data teknụzụ iji nyere aka n'iji hydroxypropyl starch eme ihe nke ọma na nhazi ngwa agha.
