Hydroxypropyl wowuma ether(HPS) ndi mtundu wa etha wowuma wotengedwa ku magwero owuma achilengedwe, monga chimanga, mbatata, kapena tapioca starch. Amagwiritsidwa ntchito kwambiri pantchito yomanga monga chowonjezera muzomangamanga zosiyanasiyana chifukwa cha zinthu zake zapadera. Tawonani ntchito ya hydroxypropyl starch ether pomanga:

1. Kusunga Madzi: HPS imagwira ntchito yosunga madzi muzomangamanga, monga matope opangidwa ndi simenti, matope, ndi zinthu zopangidwa ndi gypsum. Zimathandizira kukonza magwiridwe antchito komanso kusasinthika kwa zinthuzi pochepetsa kutayika kwa madzi pakusakaniza, kugwiritsa ntchito, ndikuchiritsa. Nthawi yotalikirapo yosungira madzi iyi imalola kuti ma hydration a simenti azitha kuyenda bwino, zomwe zimapangitsa kupititsa patsogolo kukulitsa mphamvu komanso kukhazikika kwa chinthu chomaliza.
2. Kupititsa patsogolo Kugwira Ntchito: HPS imawongolera magwiridwe antchito ndi machitidwe a zida zomangira. Powonjezera mgwirizano ndi pulasitiki wa zosakaniza za simenti, zimathandizira kusakaniza kosavuta, kupopera, ndi kugwiritsa ntchito matope ndi ma grouts. Kuthekera kogwira ntchito kumeneku kumathandizira kumaliza bwino komanso kuyika bwino kwa zida zomangira.
3. Kumamatira Kwabwino: HPS imatha kupititsa patsogolo kulumikizana pakati pa zida zomangira ndi magawo. Zikawonjezedwa ku zomatira za matailosi, zomasulira, kapena zokutira pulasitala, zimathandizira kulumikizana bwino pamalo osiyanasiyana, kuphatikiza konkriti, matabwa, matabwa, ndi gypsum board. Kumamatira bwino kumatsimikizira mgwirizano wamphamvu komanso wokhazikika, kuchepetsa chiopsezo cha delamination kapena kulephera pakapita nthawi.
4. Kuchepetsa Kugwedezeka ndi Kugwa: HPS imagwira ntchito ngati rheology modifier, yomwe imathandizira kuwongolera kuyenda ndi kusasinthasintha kwa zida zomangira. Popereka machitidwe ometa ubweya wa ubweya, amachepetsa kugwa ndi kugwa kwa ntchito zoyima kapena zapamwamba, monga kuyika matailosi, ma renders, ndi zokutira za stucco. Izi thixotropic katundu amaonetsetsa bwino dimensional bata ndi kupewa deformations pa ntchito ndi kuchiritsa.
5. Kuteteza Mng'alu: HPS ikhoza kuthandizira kuchepetsa kusweka kwa zida za simenti. Powonjezera kugwirizana ndi kulimba kwamphamvu kwa matope ndi konkire zosakaniza, zimathandiza kuchepetsa kusweka kwa shrinkage ndi kuwonongeka kwa pamwamba. Izi ndizofunikira makamaka pamagwiritsidwe ntchito omwe kukhulupirika ndi kulimba ndizofunikira kwambiri, monga kukonza konkire ndi kumaliza kokongoletsa.
6. Kugwirizana ndi Zowonjezera: HPS imagwirizana ndi zina zambiri zowonjezera zomwe zimagwiritsidwa ntchito pomanga, monga air-entraining agents, plasticizers, ndi mineral admixtures. Ikhoza kuphatikizidwa mosavuta m'mapangidwe popanda kusokoneza ntchito kapena katundu wa zigawo zina, kuonetsetsa kuti mapangidwe akhazikika komanso osasinthasintha.
7. Kukhazikika Kwachilengedwe: HPS idatengedwa kuchokera kuzinthu zowonjezedwanso komanso zowola, zomwe zimapangitsa kuti ikhale chisankho chogwirizana ndi chilengedwe pakugwiritsa ntchito zomangamanga. Zitha kuthandiza kuchepetsa kuchuluka kwa chilengedwe pa ntchito yomanga pochotsa zowonjezera zopangira ndi zina zachilengedwe.

hydroxypropyl starch ether imagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito, kugwira ntchito, komanso kulimba kwa zida zomangira. Kusungirako madzi, kukulitsa kumamatira, kuwongolera kwa rheology, komanso kupewa ming'alu kumapangitsa kuti ikhale chowonjezera chofunikira pamapangidwe osiyanasiyana omanga, zomwe zimathandizira kukhazikika komanso moyo wautali wanyumba zomangidwa.
