Ixoxa ngempembelelo ye-HEC ekusebenzeni kwengubo, njengempembelelo yayo kwi-viscosity, i-leveling, ukumelana nokuhla, kunye nokunamathela.

Intshayelelo:

I-Hydroxyethyl cellulose (HEC) yi-polymer engeyiyo ionic, enyibilikayo emanzini ephuma kwi-cellulose ngokuguqulwa kweekhemikhali. Isetyenziswa kakhulu kumashishini ahlukeneyo afana namayeza, ukhathalelo lomntu, ulwakhiwo, kunye nokufakelwa ngenxa yeempawu zayo ezikhethekileyo. Kwicandelo lokufakelwa, i-HEC isebenza imisebenzi emininzi, kubandakanya ukuqina, ukuzinzisa, kunye nokubonelela ngeempawu zokwenza ifilimu. Eli nqaku ligxile ekusetyenzisweni kwe-HEC kwiingubo kwaye liphonononga impembelelo yayo ekusebenzeni kwengubo.

Ukusetyenziswa kwe-HEC kwiingubo:

Iarhente yokutyeba:
I-HEC isebenza njengearhente yokutyeba esebenzayo kwiifomyula zokugquma. Ngokwandisa i-viscosity yesisombululo sokugquma, i-HEC iphucula uzinzo lwee-pigment kunye nezongezo, ithintela ukuhla okanye ukuhambelana ngexesha lokugcina kunye nokufaka. I-viscosity yengubo ingalungiswa ngokutshintsha uxinzelelo lwe-HEC, okuvumela ukuba iifomyula ezilungiselelweyo zihlangabezane neemfuno ezithile zokusetyenziswa. Ukongeza, i-HEC ibonelela ngokuziphatha kwe-pseudoplastic, oko kuthetha ukuba ibonisa i-viscosity ephantsi phantsi kwe-shear, okwenza kube lula ukuyisebenzisa kunye nokulinganisa i-coating.

Isilungisi seRheology:
Ukongeza ekuqineni, i-HEC isebenza njengesiguquli se-rheology kwiifomyula zokugquma. Ichaphazela indlela esebenza ngayo i-coating, iphucula iimpawu zayo zokusetyenziswa ezifana nokugudla, ukutshiza, kunye nokugudla kwe-roller. I-HEC inika indlela yokwenza i-shear-thinning kwi-coating, ivumela ukusetyenziswa okugudileyo ngelixa igcina i-viscosity xa amandla okugudla esusiwe. Le propati iluncedo kakhulu ekunciphiseni ukutshiza ngexesha lokusetyenziswa kwe-spray kunye nokuqinisekisa ukugquma okufanayo kwi-substrates ezineeprofayili ezahlukeneyo zomphezulu.

Ifilimu yangaphambili:
I-HEC inegalelo ekwakhiweni kwefilimu eqhubekayo nefanayo kumphezulu we-substrate. Njengoko i-coating yoma, iimolekyuli ze-HEC ziyahambelana ukuze zenze isakhiwo sefilimu esidibeneyo, zibonelela ngokunamathela okuhle kwi-substrate kwaye ziphucule ukuqina kwe-coating. Iimpawu zokwenza ifilimu ze-HEC zibalulekile ekufezekiseni iimpawu zokugquma ezifunekayo ezifana nokuqina, ukuguquguquka, kunye nokumelana nemozulu. Ngaphezu koko, iifilimu ze-HEC zibonisa ukumelana kakuhle kwamanzi, nto leyo ezenza zifaneleke kwiingubo ezivezwe kumswakama okanye kwiindawo ezinomswakama ophezulu.

Impembelelo ye-HEC ekusebenzeni kokugquma:

Ulawulo lokuxinana:
I-HEC ivumela ulawulo oluchanekileyo kwi-viscosity yeengubo, iqinisekisa ukuhamba kakuhle kunye neempawu zokulinganisa. Ulawulo olufanelekileyo lwe-viscosity luthintela imiba efana nokuwa, ukuvuza, okanye ukugquma okungalinganiyo ngexesha lokufaka, okukhokelela ekuphuculweni komgangatho wengubo kunye nobuhle bayo. Ngaphezu koko, indlela yokuziphatha ye-HEC yokucheba yenza kube lula ukuyisebenzisa ngaphandle kokuphazamisa ukusebenza kwengubo.

Ukumelana nokulinganisa kunye nokuhla:
Iimpawu ze-rheological ezinikezelwa yi-HEC zinegalelo ekulinganiseni nasekuqineni kweengubo. Ngexesha lokusetyenziswa, i-HEC inciphisa ukuthambekela kwengubo yokwenza amanqaku ebrashi okanye i-roller stipple, nto leyo ebangela ukuba igqitywe kakuhle kwaye ifane. Ukongeza, i-HEC iphucula indlela esebenza ngayo i-thixotropic yeengubo, ithintela ukugoba okanye ukuvuza kwiindawo ezithe nkqo, ngaloo ndlela iphucula ukusebenza kakuhle kwengubo kwaye inciphise inkunkuma yezinto.

Ukunamathela:
I-HEC iphucula ukunamathelana kweengubo kwii-substrates ezahlukeneyo, kuquka iintsimbi, iinkuni, iiplastiki kunye nekhonkrithi. Iimpawu zokwenza ifilimu ze-HEC zenza unxibelelwano oluqinileyo phakathi kwengubo kunye ne-substrate, nto leyo ephucula ukunamathelana kwexesha elide kunye nokuqina. Oku kubaluleke kakhulu kwiingubo zangaphandle ezivezwe kwiimeko ezinzima zendalo, apho ukunamathelana kudlala indima ebalulekileyo ekuthinteleni ukungaphumeleli kwengubo njengokuxobuka okanye ukususwa kwengubo.

Uphuhliso kwiTekhnoloji ye-HEC:
