Indima ye-starch ether kwizinto zokwakha

Isitashi se-ether, njengento ebalulekileyo yokuguqula imichiza, idlala indima ebalulekileyo kwizinto zokwakha. I-polymer efunyenwe ngokuguqulwa kweekhemikhali isitashi sendalo, enokuphucula kakhulu ukusebenza kwezinto zokwakha.

1. Iimpawu ezisisiseko ze-starch ethers
Isitatshi i-ether yi-non-ionic, i-polymer enyibilikayo yamanzi ikhompawundi ene-hydroxyl eninzi kunye neebhondi ze-ether kwisakhiwo sayo se-molecular. La maqela emichiza anika i-starch ethers ukutyeba okugqwesileyo, ukugcinwa kwamanzi, ukuthambisa kunye neempawu zokuncamathelisa. Ngokweendlela ezahlukeneyo zokuguqulwa kweekhemikhali, i-ethers yesitatshi inokohlulwa ibe ziindidi ezahlukeneyo ezifana ne-hydroxypropyl starch ether kunye ne-hydroxyethyl starch ether. Iindidi ezahlukeneyo ze-ethers zesitashi zineepropati ezahlukeneyo kunye nokusetyenziswa.

2. Indima ye-starch ether kwizinto zokwakha
Isiphumo sokuqina:
Xa isitashi se-ether sichithwa emanzini, sinokunyusa kakhulu i-viscosity yesisombululo se-aqueous, esenza ukuba isetyenziswe ngokubanzi njenge-thickener kwizinto zokwakha. Iindawo zayo eziphambili zesicelo ziquka i-putty powder, iingubo kunye nodaka. Ngokongeza i-starch ether, izinto zokwakha zingenziwa ukuba zibe ne-thixotropy engcono kunye nokwakhiwa, kwaye ugweme ukuhamba ngokugqithiseleyo okanye ukulungiswa kwezinto ngexesha lokwakha.

Ugcino lwamanzi:
Isitatshi ether sineempawu ezigqwesileyo zokugcina amanzi kwaye inokugcina ngokufanelekileyo ukufuma kwizinto zokwakha. Oku kubaluleke kakhulu kwizinto ezisekelwe kwi-cement, kuba i-hydration reaction ye-samente idinga ubuninzi benkxaso yomswakama. Ngokudibanisa i-ether ye-starch, isantya sokunyuka kwamanzi singancitshiswa kwaye i-samente inokuthi ifakwe ngokupheleleyo, ngaloo ndlela iphucula amandla kunye nokuqina kwezinto zokwakha.

Ukuthambisa:
I-ether yesitatshi nayo inefuthe elihle lokuthambisa kwizinto zokwakha kwaye inokuphucula ukusebenza kokwakhiwa kwezinto. Ngokukodwa ngexesha lenkqubo yokwakha, i-starch ether inokunciphisa ukungqubuzana phakathi kwezinto kunye nezixhobo zokwakha, ukwenza ukwakhiwa kube lula kunye nokuphucula ukusebenza kakuhle.

Umsebenzi wokudibanisa:
Njengepolymer yemolekyuli ephezulu, isitatshi se-ether sikwanazo iimpawu ezithile zokudibanisa kwaye inokunyusa amandla okudibanisa izinto zokwakha. Emva kokongeza i-starch ether, amandla okubambisana kwangaphakathi kunye nokunamathela kwangaphandle kwezinto kuya kuphuculwa, ngaloo ndlela kuphuculwe ukusebenza ngokubanzi kwezinto zokwakha.

3. Ukusetyenziswa kwe-ether yesitashi kwizinto ezithile zokwakha
Umgubo weputty:
Ukongeza isitashi se-ether kwi-putty powder kunokuphucula kakhulu ukusebenza kwayo kolwakhiwo kunye nokuguda komphezulu. Ukuqina kunye nokugcina amanzi kwi-ether yesitatshi kwenza ukuba i-putty powder ingabi lula ukugxumeka okanye ukuqhekeka ngexesha lenkqubo yokwakha, iqinisekisa umgangatho wokwakha.

Ukuncamatheliswa kwethayile:
I-adhesive ye-tile kufuneka ibe nokubambelela kakuhle kunye nokusebenza kokwakhiwa. Ukongezwa kwe-starch ether kunokuphucula i-viscosity kunye nokugcinwa kwamanzi kwi-adhesive tile, okwenza kube lula ngexesha lenkqubo yokwakha kwaye ikwazi ukubopha ngokuqinileyo iileyili.

Udaka lomxube owomileyo:
Ukongeza isitashi se-ether kudaka oluxutyiweyo okomileyo kunokuphucula ukuxhathisa kwe-sag kunye nokugcinwa kwamanzi kodaka, kunye nokwandisa amandla okudibanisa kunye nokuqina. Oku kubaluleke kakhulu kwizicelo ezifana neenkqubo zokugquma eludongeni lwangaphandle kunye neenkqubo zokufudumeza umgangatho.

ukutyabeka:
Ukusetyenziswa kwe-ether ye-starch kwi-coatings ikakhulu njenge-agent e-thickener kunye nokugcina amanzi ukuphucula i-rheology kunye nokusebenza kweengubo kunye nokwenza i-coating ibe yinto efanayo kwaye ihle. Kwangaxeshanye, i-ether yesitatshi inokuphucula ukusebenza kwe-anti-sag yokwambathisa kwaye ithintele ukwambathisa ekugibeni ngexesha lenkqubo yokwakha.

4. Izinto eziluncedo ze-starch ether
Ukhuseleko lokusingqongileyo:
Isitatshi se-ethers sithathwe kwisitatshi sendalo, siyahlaziyeka, sinokonakala, kwaye sinobuhlobo nokusingqongileyo. Oku kunika ukusetyenziswa kwe-ether yesitatshi kwizinto zokwakha iinzuzo ezicacileyo zokusingqongileyo kwaye ihlangabezana neemfuno zezakhiwo eziluhlaza.

ukhuseleko:
Isitashi i-ether ayinayo ityhefu kwaye ayinabungozi kwaye ayiyi kuba nefuthe elibi kwimpilo yabantu. Inkqubo yesicelo sayo ikhuselekile kwaye inokwethenjelwa, kwaye ifanelekile kwiindawo ezahlukeneyo zokwakha.

Ukusebenza kweendleko:
Xa kuthelekiswa nezinye izilungisi zeekhemikhali, isitashi se-ether sinoluhlu olubanzi lwezinto ezikrwada kwaye ixabiso layo liphantsi. Ukusetyenziswa kwayo akunakuphucula kuphela ukusebenza kwezinto zokwakha, kodwa nokunciphisa iindleko ezipheleleyo kunye nokuphucula inzuzo yezoqoqosho.

5. Iindlela zophuhliso lwexesha elizayo
Njengoko iimbono zesakhiwo esiluhlaza kunye nophuhliso oluzinzileyo luqhubeka nokujula, i-starch ethers inethemba elibanzi lokusetyenziswa kwizinto zokwakha.
