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 n'ụzọ kwesịrị ekwesị n'ụdị ngwa agha.
