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 esinamanzi, esenza ukuba sisetyenziswe ngokubanzi njengento yokutyebisa 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.
