Yintoni idyasi yeSkim?

Idyasi etyibilikayo ngumaleko obhityileyo wemathiriyeli efakwa eludongeni okanye kwisilingi ukugudisa ukungafezeki kunye nokwenza umphezulu osicaba wokupeyinta okanye ukwenza iphepha lodonga.Izinto ezisetyenziselwa ukugquma i-skim ngokuqhelekileyo ngumxube wamanzi, isamente, kunye nezinye izongezo ezifana ne-cellulose ether.

I-Cellulose ether yipolymer enyibilikayo emanzini ephuma kwi-cellulose yendalo.Isetyenziswa kakhulu kushishino lokwakha njengento ejiyayo, isizinzisi, isibophelelo, kunye nearhente yokugcina amanzi.Kwimeko ye-skim coat, i-cellulose ether yongezwa kumxube ukubonelela ngokuphuculweyo kokusebenza kunye neendawo zokugcina amanzi.

Enye yeendima ezibalulekileyo ze-cellulose ether kwi-skim coat kukukwazi ukujiya umxube.Idyasi ye-skim kufuneka ibhitye ngokwaneleyo ukuze isasazeke ngokulula ngaphezulu komphezulu kodwa ityebile ngokwaneleyo ukuzalisa naziphi na izikhewu okanye ukungafezeki.I-ether ye-cellulose inceda ekufezekiseni ukulungelelaniswa okufanelekileyo ngokunyusa umxube, okwenza kube lula ukusabalalisa ngokulinganayo phezu komhlaba.

Omnye umsebenzi obalulekileyo we-cellulose ether kwi-skim coat kukukwazi ukugcina amanzi.Idyasi yeSkim kufuneka ihlale ifumile kangangexesha elithile ukuqinisekisa ukubambelela ngokufanelekileyo kunye nokuthintela ukuqhekeka okanye ukuncipha.I-cellulose ether inceda ekugcineni amanzi kumxube, onciphisa inkqubo yokomisa kwaye iqinisekise ukuba i-skim coat ibeka ngokufanelekileyo.

I-ether ye-cellulose isebenza njenge-binder kwi-skim coat, inceda ukubamba umxube kunye nokuphucula ukunamathela kwayo phezulu.Oku kuqinisekisa ukuba i-skim coat yenza i-bond eqinile kunye nomphezulu, idala i-smooth and even surface for paint or wallpapering.

Umgangatho kunye nokusebenza kwengubo ye-skim kuphenjelelwa kakhulu luhlobo kunye nesixa se-cellulose ether esetyenzisiweyo.Kukho iintlobo ezahlukeneyo ze-cellulose ether ekhoyo kwimarike, njenge-hydroxyethyl cellulose (HEC), i-methyl cellulose (MC), kunye ne-carboxymethyl cellulose (CMC).Uhlobo ngalunye luneempawu ezahlukeneyo kunye neempawu, kwaye ukukhetha uhlobo oluchanekileyo kunye nesixa kubalulekile ekumiseleni umgangatho wengubo ye-skim.

Isishwankathelo, i-cellulose ether idlala indima ebalulekileyo kwimveliso ye-skim coat.Inika ukuqina okuyimfuneko, ukubopha, kunye nokugcinwa kwamanzi kwiipropati kumxube, oqinisekisa ukusebenza kwawo, ukuphucula ukunamathela, kunye nokuthintela ukukrazula okanye ukuncipha.Ukukhetha uhlobo oluchanekileyo kunye nomthamo we-cellulose ether kubalulekile ekuveliseni umgangatho ophezulu we-skim coat ohlangabezana nemigangatho efunwayo yoshishino lokwakha.
