3. Inkqubo yokuvelisa istatshi ether:
Ukuveliswa kwe-starch ethers kubandakanya iinkqubo ezahlukeneyo zeekhemikhali, ezifana ne-etherification kunye ne-cross-linking, ezibaluleke kakhulu ukulungelelanisa iipropati zabo ukuhlangabezana neemfuno ezithile zokubambelela.Eli candelo libonelela ngohlalutyo olunzulu lweenkqubo zokuvelisa ezibandakanyekayo ekuveliseni i-starch ethers kunye nendlela ukuhluka kwezi nkqubo kuchaphazela ngayo ukusebenza kwazo kwii-gypsum binders.
4. Indima yesitatshi ether kwi-gypsum adhesive:
Isitashi se-ethers sisebenza imisebenzi emininzi kwi-gypsum adhesives, inceda ekuphuculeni ukunamathela, ukudibanisa kunye nokusebenza kwemveliso iyonke.Eli candelo liphonononga indlela i-starch ethers esebenzisana ngayo nezinye izithako kwi-gypsum adhesive formulations, igxininisa indima yabo ekwandiseni amandla ebhondi, ukuxhathisa kwamanzi, kunye nokunciphisa i-adhesive shrinkage.
5. Izinto ezilungileyo zokusebenzisa i-starch ethers kwi-adhesives ye-gypsum:
Ukongezwa kwe-starch ethers kwi-gypsum binders kunika izibonelelo ezininzi, okwenza kube yinto yokuqala yokukhetha kwishishini lokwakha.Eli candelo linika iinkcukacha ngeenzuzo ezithile ezibandakanya ukuguquguquka kokuncamathelisa okuphuculweyo, ukuxhathisa okuphuculweyo kokufuma kunye nokusebenza okuphuculweyo ukunika ukuqonda okubanzi kweempembelelo ezilungileyo kwimixube yokuncamathelisa yegypsum.
6. Imingeni kunye nemida:
Nangona i-ethers yesitatshi ibonelela ngezinto ezininzi ezilungileyo, imingeni enokubakho kunye nezithintelo ezinxulumene nokusetyenziswa kwazo kwizibophelelo zodaka kufuneka kuvunywe.Eli candelo lixoxa ngemiba enjengoqwalaselo lweendleko, ukuhambelana nezinye izongezo, kunye nesidingo soqulunqo olufanelekileyo ukuze koyise izinto ezingeloncedo ezinokubakho.
7. Imizekelo kunye nokusetyenziswa:
Eli candelo ligxininisa kwizicelo ezisebenzayo, ezibonisa imizekelo yophando ebonisa ukusetyenziswa ngempumelelo kwe-starch ethers kwiifomyula ze-gypsum binder.Ezi zifundo ziyimizekelo ebonakalayo yendlela i-ethers yesitatshi inokwenziwa ngayo ukuze ihlangabezane neemfuno ezithile zeprojekthi, igxininisa ngakumbi ukuguquguquka kwazo kwiimeko ezahlukeneyo zokwakha.
8. Iintsingiselo zexesha elizayo kunye nezalathiso zophando:
Njengoko ishishini lokwakha likhula, injalo nemfuneko yokuphuculwa kweteknoloji yokuncamathelisa.Eli candelo liphonononga iindlela ezinokubakho kwixesha elizayo ekusetyenzisweni kwesitatshi ethers kwizibophelelo zegypsum kwaye licebisa iindlela zophando nophuhliso olongezelelweyo.Ubugcisa obuvelayo, izenzo ezizinzileyo kunye noqulunqo oluyilayo lubonwa njengeendawo ezinokubakho zophononongo.
9. Isiphelo:
Ukuqukumbela, ukongezwa kwesitatshi ethers kwi-gypsum adhesives kubonisa ukuqhubela phambili okubonakalayo kubuchwepheshe bokuncamathelisa kwishishini lokwakha.Iimpawu zayo ezinomsebenzi omninzi, kunye nokukwazi kwayo ukuphucula imiba ephambili yokusebenza kwe-adhesive, yenza ukuba ibe yinto ebalulekileyo kwi-plaster adhesive formulations.Ngokuqonda i-chemistry, iinkqubo zokuvelisa, iinzuzo, kunye nemingeni ehambelana ne-starch ethers, ishishini lokwakha lingakwazi ukuqhubeka nokunyusa le sitatshi elungisiweyo yokuphucula kunye nezisombululo zokubambelela.
