Fa'amatalaga:
Starch ethers e maua mai i le masoa e ala i le fa'aogaina o vaila'au ma e fa'aaogaina i le tele o mea tau alamanuia, o se tasi o fa'aoga iloga o lo'o fa'apipi'i gypsum. O lenei tusiga o loʻo tuʻuina atu ai se suʻesuʻega atoatoa o le matafaioi ma le taua o ethers starch i gypsum adhesives, vaʻavaʻai loloto i lona kemisi, gaosiga o gaosiga, ma le tele o faʻamanuiaga e aumaia i faʻapipiʻi faʻapipiʻi.
1 Folasaga:
Gypsum adhesives e faʻaaogaina lautele i fale faufale mo le faʻapipiʻiina o drywall, drywall, ma isi faʻaoga faʻatatau. O le faʻaopoopoga o ethers starch i nei mea faʻapipiʻi ua faʻaalia e faʻaleleia atili ai o latou uiga faʻatinoga, faʻatasi ai ma faʻamanuiaga e pei o le faʻaleleia atili o le malosi o fusi, faʻafefe vai ma le faʻaogaina. O lenei vaega o loʻo tuʻuina atu ai se faʻamatalaga lautele o le taua o mea faʻapipiʻi i totonu o le faufale faufale ma faʻamatalaina le matafaioi a le starch ethers i le faʻaleleia atili o meatotino o gypsum adhesives.
2. O mea tau vaila'au o le masoa ether:
Starch ether o se oloa masoa ua suia e ala i le suia o lona fausaga mole e ala i se gaioiga fa'a-kemikolo. O le malamalama i le kemisi o ethers masoa e taua tele i le malamalama ia latou amio i faʻapipiʻi faʻapipiʻi. O lenei vaega o loʻo suʻesuʻeina ai uiga kemikolo autu o ethers starch, e aofia ai lo latou fausaga mole, suitulaga, ma le aʻafiaga o nei suiga i mea faʻapipiʻi.
3. Fa'agasologa ole gaosiga ole masoa eter:
O le gaosiga o ethers starch e aofia ai le tele o faiga fa'a-kemikolo, e pei o le etherification ma le feso'ota'iga, e taua tele i le fa'aogaina o latou meatotino ina ia fetaui ma manaoga fa'apitoa. O lenei vaega o loʻo tuʻuina atu ai se suʻesuʻega loloto o le gaosiga o gaosiga o loʻo aʻafia ai i le gaosiga o ethers starch ma pe faʻafefea ona aʻafia ai suiga i nei gaioiga a latou gaioiga i gypsum binders.
4. O le matafaioi a le starch ether i le gypsum adhesive:
Starch ethers e tele galuega i totonu o le gypsum adhesives, fesoasoani i le faʻaleleia atili o le pipii, faʻatasi ma le faʻatinoga atoa o oloa. O lenei vaega o loʻo suʻesuʻeina pe faʻafefea ona fegalegaleai le ethers starch ma isi mea i totonu o faʻapipiʻi faʻapipiʻi gypsum, faʻamamafaina la latou matafaioi i le faʻaleleia o le malosi o fusi, faʻafefe vai, ma faʻaitiitia le faʻafefe o le pipii.
5. Tulaga lelei o le faʻaaogaina o ethers starch i gypsum adhesives:
O le faʻaopoopoga o ethers starch i gypsum binders e ofoina atu le tele o mea lelei, ma avea ai i latou ma filifiliga muamua i le fale faufale. O lenei vaega o loʻo faʻamatala auiliili ai faʻamanuiaga faʻapitoa e aofia ai le faʻaleleia atili o le pipii fetuutuunai, faʻaleleia atili o le susu ma le faʻaleleia atili o galuega e maua ai se malamalamaga atoatoa o le aʻafiaga lelei i faʻapipiʻi faʻapipiʻi gypsum.
6. Lu'i ma tapula'a:
E ui lava ina ofoina atu e le masoa ethers le tele o mea lelei, o lu'itau ma tapulaʻa e mafai ona fesoʻotaʻi ma lo latou faʻaogaina i fusi faʻapipiʻi e tatau ona faʻaalia. O lenei vaega o loʻo faʻatalanoaina mataupu e pei o iloiloga tau, fetaui ma isi faʻaopoopoga, ma le manaʻoga mo le faʻatulagaina sili ona lelei e foia ai tulaga le lelei.
7. Tulaga su'esu'ega ma fa'aoga:
O lenei vaega o loʻo taulaʻi i faʻaoga faʻaoga, tuʻuina atu o suʻesuʻega faʻataʻitaʻiga e faʻaalia ai le manuia o le faʻaogaina o ethers starch i gypsum binder formulations. O nei su'esu'ega fa'ata'ita'iga o ni fa'ata'ita'iga fa'apitoa e mafai ona fa'amaninoina ethers masoa e fa'amalieina ai mana'oga fa'apitoa o le poloketi, ma fa'amamafa atili ai lo latou agava'a i fa'aaliga faufale eseese.
8. Tulaga i le lumana'i ma fa'atonuga o su'esu'ega:
A'o fa'atuputeleina le faufale, e fa'apea fo'i le mana'omia mo le fa'aleleia atili o tekonolosi fa'apipi'i. O lenei vaega o lo'o su'esu'eina ai le lumana'i i le fa'aogaina o ethers masoa i gypsum binders ma fa'ailoa mai ai ni auala mo su'esu'ega atili ma atina'e. O fa'atekonolosi fa'afou, faiga fa'atumauina ma fa'ata'ita'iga fou ua va'aia o ni vaega e mafai ona su'esu'eina.
9. Fa'ai'uga:
I le faʻaiʻuga, o le faʻaopoopoga o ethers starch i gypsum adhesives o loʻo faʻaalia ai se alualu i luma taua i tekinolosi faʻapipiʻi mo le fale faufale. O ona uiga fa'apitoa, fa'atasi ai ma lona gafatia e fa'aleleia ai vaega taua o le fa'aogaina o le fa'apipi'i, e avea o se vaega taua i fa'apipi'i fa'apipi'i. E ala i le malamalama i le kemisi, faiga o gaosiga, fa'amanuiaga, ma lu'itau e feso'ota'i ma ethers starch, e mafai e le alamanuia faufale ona fa'aauau pea le fa'aogaina o lenei masoa ua suia mo le fa'aleleia atili ma le gafataulimaina o vaifofo pipi'i.
