Imikhiqizo esekwe ku-Gypsum, efana nokhonkolo namabhodi wodonga, iyizinto ezibalulekile embonini yezokwakha. Ukuthandwa kwazo kungenxa yokuguquguquka kwazo, ukusebenziseka kalula, kanye nezindawo ezifiselekayo njengokumelana nomlilo nokusebenza kwe-acoustic. Kodwa-ke, izinselele ezihlobene nokugcinwa kwamanzi nesikhathi sokomisa ziyaqhubeka, zibe nomthelela ekusebenzeni kwawo nokusebenza kwawo. Intuthuko yakamuva yethule ama-starch ether njengezithasiselo ekwakhiweni kwe-gypsum, enikeza ukuthuthuka okubalulekile ekugcinweni kwamanzi kanye nezikhathi zokomisa.
Ukuqonda Isitashi Ethers
Isitashi ether isitashi esishintshiwe esitholakala ngokwethula amaqembu e-ether ku-molecule yesitashi. Lokhu kuguqulwa kuthuthukisa ukugcinwa kwamanzi kwesitashi, ukujiya, nokubopha, kusenze sibe isithasiselo esifanelekile sezinto zokwakha. Ama-starch ethers akhiqizwa emithonjeni yemvelo efana nommbila, amazambane, noma ukolweni, okuqinisekisa ukuthi ahambisana nemvelo futhi azinzile.
Indlela Yokwenza
Umsebenzi oyinhloko we-starch ethers emikhiqizweni esekelwe ku-gypsum ukuthuthukisa ukugcinwa kwamanzi. Lokhu kufezwa ngokusebenzisa ikhono labo lokwenza izibopho ze-hydrogen nama-molecule wamanzi, okwenza inethiwekhi evalela amanzi ngaphakathi kwe-matrix. Le nethiwekhi inciphisa izinga lokuhwamuka, iqinisekisa ukuthi i-gypsum inesikhathi esanele sokunisela futhi isethwe kahle. Ukwengeza, i-starch ethers iguqula izakhiwo ze-rheological ze-gypsum slurry, ithuthukise ukusebenza kwayo nokusebenza kwayo.
Ukugcina Amanzi
Emikhiqizweni ye-gypsum, ukugcinwa kwamanzi okwanele kubalulekile ukuze i-hydration efanele ye-calcium sulfate hemihydrate (CaSO4 · 0.5H2O) yakhe i-calcium sulfate dihydrate (CaSO4 · 2H2O). Le nqubo ye-hydration ibalulekile ekuthuthukiseni amandla emishini kanye nezakhiwo zokugcina zomkhiqizo. Ama-ethers esitashi, ngokubamba amanzi ku-matrix, aqinisekisa ukuthi i-gypsum ingakwazi ukufaka amanzi ngokugcwele, okuholela kumkhiqizo wokugcina oqinile futhi ohlala njalo.
Ukunciphisa Isikhathi Sokomisa
Nakuba kungase kubonakale kuphambene, ukugcinwa kwamanzi okuthuthukisiwe okwenziwa ama-starch ether empeleni kunomthelela ekwehliseni isikhathi sokumisa sisonke. Lokhu kungenxa yokuthi ukukhishwa okulawulwayo kwamanzi kuvumela inqubo efanayo futhi ephelele ye-hydration, ukunciphisa ingozi yeziphambeko ezifana nokuqhekeka noma izindawo ezibuthakathaka. Ngenxa yalokho, inqubo yokomisa iba nempumelelo kakhudlwana, okuholela esikhathini sokumisa esisheshayo.
Izinzuzo ze-Starch Ethers emikhiqizweni esekwe eGypsum
Ukusebenza Okuthuthukisiwe
Isitashi ethers sithuthukisa i-rheology ye-gypsum slurries, okwenza kube lula ukuxutshwa nokusetshenziswa. Lokhu kuzuzisa kakhulu ekusetshenzisweni kwesifutho nalapho usebenza ngesikhunta esiyinkimbinkimbi noma imiklamo eyinkimbinkimbi. Ukuvumelana okuthuthukisiwe kunciphisa umzamo odingekayo wokufaka i-gypsum futhi kuqinisekisa ukushelela, ukuqeda okufanayo.
Izakhiwo Zemishini Ethuthukisiwe
Ngokuqinisekisa ukugeleza kwamanzi okuphelele, ama-ethers esitashi athuthukisa izakhiwo zemishini yemikhiqizo esekwe ku-gypsum. Izinto eziwumphumela zibonisa amandla aphezulu acindezelayo nanamandla, ukunamathela okungcono, nokuqina okwandisiwe. Lokhu kuthuthukiswa kwandisa ubude bempilo bemikhiqizo futhi kuthuthukise ukusebenza kwayo ezinhlelweni ezihlukahlukene.
Ukuqhekeka Okuncishisiwe Nokuncipha
Enye yezinkinga ezivamile ngemikhiqizo ye-gypsum ukuqhekeka kanye nokuncipha ngesikhathi sokumisa. Ama-ether esitashi anciphisa le nkinga ngokugcina amazinga omswakamo alungile kuso sonke isigaba sokusetha. Lokhu kukhishwa komswakama okulawulwayo kunciphisa ukucindezeleka kwangaphakathi futhi kuvimbela ukwakheka kwemifantu, okuholela ekuqedeni okuzinzile nokubukeka kahle.
Ukusimama
Ama-ethers esitashi athathwe ezinsizeni ezivuselelekayo, okuwenza abe yinketho evumelana nemvelo embonini yezokwakha. Ukusetshenziswa kwabo emikhiqizweni ye-gypsum akugcini nje ngokuthuthukisa ukusebenza kodwa futhi kuhambisana nesidingo esikhulayo sezinto zokwakha ezisimeme. Lokhu kufaka isandla ezenzweni zokwakha eziluhlaza futhi kunciphisa indawo ezungezile yamaphrojekthi wokwakha.
Izicelo ze-Starch Ethers emikhiqizweni esekwe eGypsum
Upulasi
Ekufakweni kwe-plaster, ama-ethers esitashi athuthukisa ukukhululeka kokusabalalisa nokubeka izinga, okuholela ekubeni bushelelezi futhi bulingane. Ukugcinwa kwamanzi okuthuthukisiwe kuqinisekisa ukuthi ukhonkolo luhlala lusebenza isikhathi eside, lunciphisa ukungcola nokwandisa ukusebenza kahle endaweni. Ukwengeza, isikhathi sokumisa esincishisiwe sivumela ukuqedwa okusheshayo nokudweba, ukusheshisa izikhathi zephrojekthi.
Amabhodi odonga
Amabhodi odonga e-Gypsum azuza kakhulu ekufakweni kwe-starch ethers. Amandla athuthukisiwe nokuqina kuhumusha ekumelaneni kangcono nomthelela nokuguga, okubalulekile ezindaweni ezinethrafikhi ephezulu. Isikhathi esincishisiwe sokumisa nokusebenza okuthuthukisiwe nakho kusiza imijikelezo yokukhiqiza esheshayo nokufaka kalula, okwenza amabhodi odonga angabizi kakhulu futhi asebenziseke.
Izithako Ezihlangene
Kumakhompiyutha ahlangene, ama-starch ether ahlinzeka ngezakhiwo ezinhle kakhulu zokubopha, ukuqinisekisa amalunga angenamthungo futhi anciphisa amathuba okuqhekeka emigqeni. Ukuvumelana okuthuthukisiwe nokusebenza kwenza isicelo sibe lula, kuyilapho ukugcinwa kwamanzi okuthuthukisiwe kuqinisekisa ibhondi eqinile nehlala isikhathi eside.
I-Case Studies kanye Nezibonelo Zomhlaba Wangempela
Ucwaningo oluthile lwezikesi lubonise izinzuzo ze-starch ethers emikhiqizweni esekelwe ku-gypsum. Isibonelo, iphrojekthi yokwakha esebenzisa isikhonkwane esilungisiwe sesitashi se-ether ibike ukuncishiswa kwesikhathi sokumisa ngo-30% kanye nokwehla okukhulu kokuqhekeka uma kuqhathaniswa nokwakheka kukakhonkolo okuvamile. Olunye ucwaningo kuma-wallboard e-gypsum lubonise ukukhuphuka okungama-25% kokumelana nomthelela kanye nesiphetho esishelelayo, okubangelwa ukugeleza kwamanzi okuthuthukisiwe nokusebenza okuhlinzekwa ama-starch ethers.
Izinselele kanye Neziqondiso Zesikhathi esizayo
Nakuba izinzuzo ze-starch ethers zibhalwe kahle, izinselele zisekhona ekuthuthukiseni ukusetshenziswa kwazo ekwakhiweni okuhlukile kwe-gypsum. Ucwaningo luyaqhubeka lokulungisa kahle ukugxila kanye nohlobo lwama-ether esitashi ezinhlelweni ezihlukene, ukuqinisekisa izinzuzo zokusebenza eziphezulu. Intuthuko yesikhathi esizayo ingase igxile ekuthuthukiseni ukuhambisana kwesitashi ether nezinye izithasiselo kanye nokuhlola imithombo emisha yesitashi ukuze kuqhubeke ukusimama okukhulu.
Ama-ether esitashi amele intuthuko enkulu ekwenziweni kwemikhiqizo esekwe ku-gypsum, enikeza ukugcinwa kwamanzi okuthuthukisiwe kanye nezikhathi zokomisa ezincishisiwe. Lezi zinzuzo zihumusha ekusebenzeni okuthuthukisiwe, izakhiwo ezingcono zemishini, kanye nokusimama okwandisiwe. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukwamukelwa kwe-starch ethers emikhiqizweni ye-gypsum cishe kuzokhula, kuqhutshwa isidingo sezinto zokwakha ezisebenza kahle, ezihlala isikhathi eside, nezingangeni imvelo. Ngokusebenzisa izici zemvelo zama-starch ethers, imboni ingafinyelela ukusebenza okuphezulu futhi ifake isandla ezenzweni zokwakha ezizinzile.
