Indima yesitashi ether ezintweni zokwakha

I-starch ether, njengesiguquli samakhemikhali esibalulekile, idlala indima ebalulekile ezintweni zokwakha. Kuyi-polymer etholwe ngokushintsha isitashi semvelo ngamakhemikhali, okungathuthukisa kakhulu ukusebenza kwezinto zokwakha.

1. Izici eziyisisekelo ze-starch ethers
I-starch ether iyinhlanganisela engeyona i-ionic, i-polymer encibilika emanzini ene-hydroxyl eminingi nebhondi ye-ether esakhiweni sayo samangqamuzana. Lawa maqembu amakhemikhali anikeza ama-starch ethers ukujiya okuhle kakhulu, ukugcinwa kwamanzi, ukuthambisa kanye nezakhiwo zokunamathela. Ngokwezindlela ezihlukene zokuguqula amakhemikhali, ama-starch ether angahlukaniswa abe izinhlobo ezahlukene ezifana ne-hydroxypropyl starch ether ne-hydroxyethyl starch ether. Izinhlobo ezahlukene zama-ethers anesitashi zinezakhiwo ezihlukene kanye nokusetshenziswa kwazo.

2. Indima yesitashi ether ezintweni zokwakha
Umthelela wokujiya:
Lapho isitashi se-ether sichithwa emanzini, singandisa kakhulu i-viscosity yesisombululo se-aqueous, okwenza sisetshenziswe kabanzi njenge-thickener ezintweni zokwakha. Izindawo zayo eziyinhloko zokufaka isicelo zihlanganisa i-putty powder, i-coatings kanye nodaka. Ngokungeza i-starch ether, izinto zokwakha zingenziwa zibe ne-thixotropy engcono nokwakhiwa, futhi zigweme ukugeleza ngokweqile noma ukuxazululwa kwezinto ngesikhathi sokwakhiwa.

Umthelela wokugcina amanzi:
I-starch ether inezindawo ezinhle kakhulu zokugcina amanzi futhi ingagcina ngempumelelo umswakama ezintweni zokwakha. Lokhu kubaluleke kakhulu ezintweni ezisekelwe ku-cement, ngoba ukusabela kwe-hydration ye-cement kudinga inani elithile lokusekela umswakama. Ngokufaka i-starch ether, izinga lokuhwamuka kwamanzi lingancishiswa futhi usimende ungabi namanzi ngokugcwele, ngaleyo ndlela kuthuthukiswe amandla nokuqina kwezinto zokwakha.

Ukuthambisa:
I-starch ether nayo inomphumela omuhle wokugcoba ezintweni zokwakha futhi ingathuthukisa ukusebenza kokwakhiwa kwezinto. Ikakhulukazi phakathi nenqubo yokwakha, i-starch ether inganciphisa ukungqubuzana phakathi kwezinto zokwakha namathuluzi okwakha, okwenza ukwakhiwa kube bushelelezi futhi kuthuthukise ukusebenza kahle kokwakhiwa.

Umsebenzi wokuhlanganisa:
Njengepholymer yamangqamuzana aphezulu, isitashi ether sinezici ezithile zokubopha futhi ingathuthukisa amandla okubopha wezinto zokwakha. Ngemuva kokwengeza i-starch ether, amandla okubopha kwangaphakathi kanye nokunamathela kwangaphandle kwempahla kuzothuthukiswa, ngaleyo ndlela kuthuthukiswe ukusebenza okuphelele kwezinto zokwakha.

3. Ukusetshenziswa kwesitashi ether ezintweni ezithile zokwakha
I-putty powder:
Ukwengeza i-starch ether ku-putty powder kungathuthukisa kakhulu ukusebenza kwayo kokwakhiwa kanye nokushelela kwendawo. Ukuqina nokugcina amanzi imiphumela ye-starch ether yenza i-putty powder mancane amathuba okuba igxume noma iqhekeke phakathi nenqubo yokwakha, iqinisekisa ikhwalithi yokwakha.

I-adhesive yethayela:
I-adhesive ye-tile idinga ukuba nokunamathela okuhle nokusebenza kokwakhiwa. Ukwengezwa kwe-starch ether kungathuthukisa i-viscosity nokugcinwa kwamanzi kwe-adhesive tile, okwenza kube bushelelezi ngesikhathi senqubo yokwakha futhi ikwazi ukubopha ngokuqinile amathayili.

Udaka lwemiksi eyomile:
Ukwengeza i-starch ether odakeni oluxutshwe okomile kungathuthukisa ukumelana ne-sag kanye nokugcinwa kwamanzi kodaka, futhi kuthuthukise amandla ayo okubopha kanye nokuqina. Lokhu kubaluleke kakhulu ezinhlelweni ezifana nezinhlelo zokuvikela udonga zangaphandle kanye namasistimu okushisa aphansi.

ukunamathela:
Ukusetshenziswa kwe-starch ether ekugqokeni ikakhulukazi njenge-ejenti yokuqina kanye ne-agent egcina amanzi ukuze kuthuthukiswe i-rheology nokusebenza kwezingubo zokugqoka futhi wenze ukumboza kufane futhi kube kuhle. Ngesikhathi esifanayo, i-starch ether ingaphinde ithuthukise ukusebenza kwe-anti-sag ye-coating futhi ivimbele ukugoqa ekugwemeni ngesikhathi senqubo yokwakha.

4. Izinzuzo ze-starch ether
Ukuvikelwa kwemvelo:
Ama-ether esitashi asuselwa kusitashi semvelo, ayavuseleleka, ayabola, futhi anobungani nemvelo. Lokhu kunikeza ukusetshenziswa kwesitashi ether ezintweni zokwakha izinzuzo ezisobala zemvelo futhi kuhlangabezana nezidingo zezakhiwo eziluhlaza.

ukuphepha:
I-starch ether ayinabo ubuthi futhi ayinabungozi futhi ngeke ibe nomthelela omubi empilweni yomuntu. Inqubo yokufaka isicelo iphephile futhi inokwethenjelwa, futhi ifanele izindawo ezihlukahlukene zokwakha.

Ukusebenza kahle kwezindleko:
Uma kuqhathaniswa namanye ama-modifiers amakhemikhali, isitashi ether sinezinhlobonhlobo zezinto ezingavuthiwe futhi izindleko zaso ziphansi kakhulu. Ukusetshenziswa kwayo akukwazi nje ukuthuthukisa ukusebenza kwezinto zokwakha, kodwa futhi kunciphise izindleko eziphelele futhi kuthuthukise izinzuzo zezomnotho.

5. Izitayela zentuthuko yesikhathi esizayo
Njengoba imiqondo yokwakhiwa okuluhlaza kanye nentuthuko esimeme iqhubeka nokujula, ama-starch ether anamathemba abanzi okusetshenziswa ezintweni zokwakha. Ngokuzayo, ngokuthuthuka kwesayensi nobuchwepheshe, ukusebenza nokusetshenziswa kwezinkambu ze-starch ether kuzokwandiswa nakakhulu. Isibonelo, ngokuqhubeka nokuthuthukisa ukwakheka kwamangqamuzana e-starch ether, izilungisi ezisebenza kahle zingathuthukiswa ukuze zihlangabezane nezidingo zezinto zokwakha ezahlukahlukene. Ukwengeza, ukusetshenziswa kwe-starch ethers ezintweni zokwakha ezihlakaniphile kanye nezinto zokwakha ezisebenzayo nakho kuzoba indawo yokucwaninga, okuletha ukuqamba okusha kanye nentuthuko embonini yezokwakha.

Njengesiguquli esibalulekile sezinto zokwakha, i-starch ether idlala indima ebalulekile ezintweni zokwakha ngenxa yokuqina kwayo okuhle kakhulu, ukugcinwa kwamanzi, ukuthambisa kanye nezakhiwo zokubopha. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusetshenziswa kwe-starch ether kuzoba kubanzi, kusize imboni yezokwakha ukuthi ifinyelele intuthuko esimeme.
