Starch ether, dị ka ihe mgbanwe kemịkalụ dị mkpa, na-arụ ọrụ dị mkpa n'ime ihe owuwu ụlọ. Ọ bụ polymer nwetara site na-agbanwe starch eke ekemịkal, nke nwere ike imeziwanye arụmọrụ nke ihe ụlọ.
1. Ihe ndị bụ isi nke starch ethers
Starch ether bụ ihe na-abụghị ionic, mmiri-soluble polymer compound nwere otutu hydroxyl na ether bond na molekụla nhazi ya. Otu kemịkalụ ndị a na-enye starch ethers ezigbo mgbodo, njide mmiri, mmanu mmanu na nrapado. Dịka ụzọ mgbanwe kemịkalụ dị iche iche si dị, enwere ike kewaa starch ethers n'ụdị dị iche iche dịka hydroxypropyl starch ether na hydroxyethyl starch ether. Ụdị starch ether dị iche iche nwere ihe dị iche iche na ngwa.
2. Ọrụ nke starch ether na ihe owuwu ụlọ
Mmetụta siri ike:
Mgbe ether starch agbazere na mmiri, ọ nwere ike ịbawanye viscosity nke mmiri mmiri ngwọta nke ukwuu, nke na-eme ka a na-ejikarị dị ka thickener na-ewu ihe. Ebe isi ngwa ya gụnyere putty ntụ ntụ, mkpuchi na ngwa agha. Site n'ịgbakwunye starch ether, ihe ụlọ nwere ike ime ka thixotropy dị mma na ịrụ ọrụ nke ọma, ma zere oke eruba ma ọ bụ nhazi nke ihe n'oge a na-ewu.
Mmetụta njide mmiri:
Starch ether nwere ezigbo njide mmiri ma nwee ike ijigide mmiri nke ọma na ihe ụlọ. Nke a dị mkpa karịsịa maka ihe ndị dabeere na ciment, n'ihi na mmeghachi omume hydration nke ciment chọrọ ụfọdụ nkwado mmiri. Site n'ịgbakwụnye starch ether, ọnụ ọgụgụ mmiri nke evaporation nke mmiri nwere ike belata na ciment nwere ike ịme ka mmiri dị ọcha, si otú a na-eme ka ike na ịdịte aka nke ihe ụlọ.
mmanu mmanu:
Starch ether nwekwara mmetụta lubrication dị mma na ihe owuwu ụlọ ma nwee ike melite arụmọrụ nke ihe. Karịsịa n'oge usoro ihe owuwu, starch ether nwere ike ibelata esemokwu n'etiti ihe na ngwá ọrụ ihe owuwu, na-eme ka ihe owuwu dị nro ma na-emeziwanye arụmọrụ ihe owuwu.
Ọrụ njikọ:
Dị ka polymer molekụla dị elu, starch ether nwekwara ụfọdụ ihe jikọrọ ọnụ ma nwee ike ịkwalite ike njikọ nke ihe ụlọ. Mgbe ị gbakwụnye starch ether, a ga-eme ka ike nke ime ime na nkwụsị nke ihe dị n'ime ya dịkwuo mma, si otú ahụ na-eme ka arụmọrụ zuru ezu nke ihe owuwu ahụ dịkwuo mma.
3. Ngwa nke starch ether na ihe owuwu ụlọ kpọmkwem
ntụ ntụ Putty:
Ịgbakwunye starch ether na putty ntụ ntụ nwere ike imeziwanye arụmọrụ ihe owuwu ya na ịdị nro n'elu ya. Mmetụta na-ekpo ọkụ na mmiri na-ejide mmiri nke starch ether na-eme ka ntụ ntụ na-eme ka ọ ghara ịdaba ma ọ bụ ịgbawa n'oge usoro ihe owuwu, na-eme ka ihe owuwu dị mma.
Ihe nrapado tile:
Ihe ntanye tile kwesịrị inwe ezigbo nrapado na ịrụ ọrụ ihe owuwu. Mgbakwunye nke starch ether nwere ike imeziwanye viscosity na njigide mmiri nke nrapado tile, na-eme ka ọ dị nro n'oge a na-ewu ụlọ ma nwee ike ijikọ taịl nile.
Ngwakọta ngwakọta akọrọ:
Ịtinye starch ether na ngwa agha agwakọtara akpọnwụ nwere ike melite nguzogide sag na njigide mmiri nke ngwa agha ahụ, ma welie ike njikọ ya na ịdịte aka ya. Nke a dị mkpa karịsịa maka ngwa dị ka usoro mkpuchi mgbidi dị n'èzí na usoro ikpo ọkụ n'ala.
mkpuchi:
Ngwa nke starch ether na mkpuchi bụ tumadi dị ka onye na-ekpuchi mmiri na mmiri na-eme ka ọkpụkpụ na-arụ ọrụ nke ọma na-eme ka ihe mkpuchi ahụ dịkwuo mma ma mara mma. N'otu oge ahụ, starch ether nwekwara ike imeziwanye arụmọrụ mgbochi sag nke mkpuchi ahụ ma gbochie mkpuchi ahụ ka ọ ghara ịda mbà n'oge usoro ihe owuwu.
4. Uru nke starch ether
Nchedo gburugburu ebe obibi:
A na-enweta starch ethers site na starch eke, a na-emegharịgharị, na-emebi emebi, na enyi na gburugburu ebe obibi. Nke a na-enye ngwa nke starch ether na ihe owuwu ụlọ doro anya uru gburugburu ebe obibi na izute ihe ndị a chọrọ nke ụlọ akwụkwọ ndụ akwụkwọ ndụ.
nchekwa:
Starch ether adịghị egbu egbu na adịghị emerụ ahụ ma ọ gaghị enwe mmetụta ọjọọ na ahụike mmadụ. Usoro ntinye ya dị mma ma bụrụ nke a pụrụ ịdabere na ya, ọ dịkwa mma maka gburugburu ihe owuwu dị iche iche.
Ọnụ ọnụ ahịa:
E jiri ya tụnyere ndị na-eme mgbanwe kemịkalụ ndị ọzọ, starch ether nwere ọtụtụ ngwa ngwa na ọnụ ahịa ya dị ntakịrị. Ngwa ya nwere ike ọ bụghị naanị imeziwanye arụmọrụ nke ihe ụlọ, kamakwa belata ọnụ ahịa n'ozuzu ya ma melite uru akụ na ụba.
5. Ọdịnihu mmepe ọnọdụ
Ka echiche nke ụlọ akwụkwọ ndụ akwụkwọ ndụ na mmepe na-adịgide adịgide na-aga n'ihu, starch ethers nwere atụmanya sara mbara maka itinye n'ime ihe owuwu ụlọ. N'ọdịnihu, na ọganihu nke sayensị na nkà na ụzụ, arụmọrụ na ngwa ngwa nke starch ether ga-agbasawanye. Dịka ọmụmaatụ, site n'ịkwalite usoro ihe omimi nke starch ethers, enwere ike ịmepụta ihe ndị na-arụ ọrụ nke ọma iji gboo mkpa nke ihe ụlọ dị iche iche. Tụkwasị na nke ahụ, ntinye nke starch ethers na ihe ụlọ nwere ọgụgụ isi na ihe ụlọ na-arụ ọrụ ga-abụkwa ebe nyocha, na-eweta ihe ọhụrụ na mmepe na ụlọ ọrụ mmepụta ihe.
Dị ka ihe dị mkpa na-emezi ihe ụlọ, starch ether na-arụ ọrụ dị mkpa n'ime ihe owuwu ụlọ n'ihi na ọ na-eme ka ọ dịkwuo mma, njide mmiri, mmanye na njikọta. Site na ọganihu teknụzụ na-aga n'ihu, ntinye nke starch ether ga-aba ụba karị, na-enyere ụlọ ọrụ mmepụta ihe aka inweta mmepe na-adịgide adịgide.
