1. Intshayelelo kwi-hydroxyethyl methylcellulose
I-Hydroxyethyl Methyl Cellulose (HEMC)yi-ether ye-cellulose e-non-ionic emanzini e-soluble ether eveliswa ngokuphendula kweekhemikhali ezifana ne-alkalinization kunye ne-etherification ye-cellulose yendalo. Inokuqina okugqwesileyo, ukugcinwa kwamanzi, ukwenza ifilimu, i-lubrication kunye neempawu zokudibanisa kwaye isetyenziswa ngokubanzi kwizinto zokwakha, iingubo, amayeza, ukutya kunye nezinye iindawo. Kwintsimi yokwakha, ngokukodwa kwidaka elomileyo kunye ne-putty powder, i-HEMC idlala indima ebalulekileyo.
2. Indima yokuphucula ukuqhubekeka
Ukuphucula ukusebenza kolwakhiwo
Phakathi kwezinto zokwakha, i-HEMC ineempawu ezigqwesileyo zokujiya kwaye inokuphucula ngokufanelekileyo i-thixotropy kunye nokumelana ne-sag yezinto. Olu phawu lwenza ulwakhiwo lube lula ngakumbi. Ngokukodwa xa usebenzisa kwiindawo ezithe nkqo, izinto eziphathekayo akulula ukugoba, okwenza kube lula kubaqhubi ukuba benze i-coating efanayo kunye nokuphucula ukusebenza kakuhle kokwakhiwa.
i-rial inokuhlala ifanelekile ixesha elide emva kokugqunywa okanye ukushukunyiswa. Oku kuthenga abasebenzi bokwakha ixesha elingakumbi lohlengahlengiso kunye nezilungiso kunye nokuphucula umgangatho wokwakha.
3. Indima yokuphucula intsebenzo
Iipropati ezigqwesileyo zokugcina amanzi
Enye yeepropati eziphawulekayo ze-HEMC kukugcinwa kwayo kakuhle kwamanzi. Kwi-samente-based based or gypsum-based mortars, i-HEMC inokunciphisa ngokufanelekileyo ukulahlekelwa kwamanzi kwaye iqinisekise ukuba i-samente okanye i-gypsum inomswakama owaneleyo ngexesha lokuphendula kwe-hydration. Oku akuphuculi nje kuphela amandla kunye nokudibanisa kwezinto eziphathekayo, kodwa kunciphisa umngcipheko wokuqhekeka kunye nokugoba.
Ukuphucula ukunamathela
Ekubeni i-HEMC ineempawu ezintle zokwenza ifilimu, inokwenza ifilimu efanayo kwindawo yokwakha, ngaloo ndlela ikhulise ukunamathela phakathi kwezinto kunye ne-substrate. Le propati ibaluleke kakhulu kwizicelo ezifana ne-tile adhesives kunye ne-putty, apho inokuphucula kakhulu ukuqina nokuzinza.
Phucula ukuxhathisa ukunyibilika komkhenkce
Kwiindawo ezibandayo ezibandayo, ukuchasana kwe-freeze-thaw yezinto kubaluleke kakhulu. I-HEMC iphucula ukuxhathisa kwemozulu yezinto ngokulungisa ukusabalalisa ukufuma ngaphakathi kwezinto kunye nokunciphisa utshintsho lwevolumu olubangelwa ngumkhenkce kunye nokunyibilika kwamanzi ngexesha lomjikelo wokuqhaqhazela.
4. Iimeko eziqhelekileyo kwizicelo ezibonakalayo
udaka olomileyo
Ngodaka olomileyo, i-HEMC ayiphuculi kuphela ukugcinwa kwamanzi kunye nokusebenza komdaka, kodwa iphinda ikhulise ukusebenza kwezinto eziphathekayo, okwenza ukuba udaka lube lula ukusabalalisa kunye nokubumba ngexesha lokwakha.
Iglu yethayile
I-HEMC inokuphucula i-colloid ye-bonding force kwi-ceramic tile adhesives, iqinisekisa uxhulumaniso oluqinileyo phakathi kweetayile ze-ceramic kunye ne-substrates, kunye nokunciphisa i-slippage yezinto ngexesha lokwakha.
Umgubo weputty
Phakathi kwe-putty powders, i-HEMC inokuphucula ukugudisa kwendawo, iphucule ukuxhathisa kwamanzi kunye nokumelana nokuqhekeka kwengubo, kwaye yenze i-putty layer isebenze ngcono kulwakhiwo olulandelayo (njengepeyinti ye-latex).
IHydroxyethyl methylcellulose iye yaba sisongezo esiyimfuneko nesibalulekileyo kwizinto zokwakha zale mihla ngenxa yokuqina kwayo okugqwesileyo, ukugcinwa kwamanzi, ukuthambisa kunye nezinye iipropathi. Ayiphuculi kakhulu kuphela ukuqhubekeka kwezinto, kodwa ikwaphucula ukusebenza kunye nokuqina kweemveliso ezigqityiweyo, izisa ukukhululeka okukhulu kunye neenzuzo kubasebenzi bokwakha kunye nabasebenzisi. Ngokuqhubela phambili okuqhubekayo kobuchwepheshe, imimandla yesicelo kunye nemiphumo ye-HEMC iya kwandiswa ngakumbi, ukunika uncedo olungakumbi kuphuhliso loshishino lokwakha.
