I-Hydroxyethyl methylcellulose (HEMC), njenge-polymer compound esetyenziswa rhoqo emanzini, ineenzuzo ezibalulekileyo kwiingubo ezisekwe kwisamente. Ulwakhiwo lwayo lweekhemikhali luyivumela ukuba idlale indima ebalulekileyo ekuphuculeni ukusebenza kweengubo ezisekwe kwisamente.
1. Phucula ukusebenza kolwakhiwo
Ngexesha lenkqubo yokwakha ii-coating ezisekelwe kwisamente, ukutyibilika kunye nokusebenza kakuhle zizinto ezibalulekileyo ezichaphazela umgangatho we-coating kunye nokusebenza kakuhle kolwakhiwo. I-HEMC inokuphucula kakhulu ukusebenza kwe-coating ngokunyusa i-viscosity kunye nokugcinwa kwamanzi kwee-coating. Ukusebenza okuthe ngqo yile:
Ukuphucula ukusebenza kwepeyinti: I-HEMC inokunyusa ukuhambelana kwepeyinti, okwenza kube lula ukulawula ipeyinti ngexesha lenkqubo yokugquma kwaye kuthintelwe iingxaki ezifana nokugeleza nokuvuza kwepeyinti.
Ukuphucula ukugcinwa kwamanzi kweengubo: I-HEMC inokuphucula ukugcinwa kwamanzi kweengubo ezisekelwe kwisamente, inciphise izinga lokuphuma kwamanzi emkhenkceni, kwaye iqinisekise ukufana kunye nozinzo lwengubo.
Olu phawu lufanelekile ngokukodwa kwiimeko zokwakha ezifuna ukusebenza ixesha elide. Lunokuqinisekisa ukuba i-samente slurry ayizomi ngaphambi kwexesha ngexesha lenkqubo yokwakha i-coating, ngaloo ndlela iqinisekisa umgangatho we-coating.
2. Yandisa iiyure zokuvula
Ixesha lokuvula ipeyinti esekwe kwisamente lixesha emva kokuba ipeyinti isetyenzisiwe apho isenokusetyenziswa okanye igqitywe. Njengesithambisi esisebenzayo, i-HEMC inokwandisa ixesha lokuvula ipeyinti esekwe kwisamente, ngaloo ndlela inyusa ukuguquguquka kolwakhiwo. Emva kokongeza i-HEMC kwipeyinti esekwe kwisamente, abasebenzi bokwakha banokuba nexesha elingakumbi lokulungisa ipeyinti kunye nokucheba ukuze baphephe iingxaki ezibangelwa kukucocwa ngokukhawuleza kwepeyinti.
3. Phucula ukunamathela kwepeyinti
I-HEMC inokuphucula ngempumelelo ukunamathelana phakathi kwengubo kunye ne-substrate kwiingubo ezisekwe kwisamente, ingakumbi kwiindawo ezithambileyo okanye ezinzima ukunamathela (ezifana nesinyithi, iglasi, njl.njl.). Ukongezwa kwe-HEMC kunokuphucula kakhulu ukunamathela kwengubo. Ingqwalasela. Ngale ndlela, ayiphuculwanga nje kuphela ukuqina kwengubo, kodwa nobuchule bokulwa nokuwa kwengubo buyaphuculwa.
4. Phucula ukumelana nokuqhekeka kweengubo
Iingubo ezisekwe kwisamente zidla ngokuqhekeka ngexesha lenkqubo yokucola, ingakumbi kwiingubo ezixineneyo okanye kwiindawo ezinobushushu obuphezulu. I-HEMC inokuphucula ukuthamba kweengubo ngokusebenzisa isakhiwo sayo esikhethekileyo se-molecular, inciphise ukuncitshiswa komthamo okubangelwa kukuguquguquka kwamanzi, kwaye inciphise ukwenzeka kweentanda. I-HEMC inokunxibelelana nezinye izinto kwisamente ukwenza isakhiwo senethiwekhi esizinzileyo, iphucule ngakumbi ukuqina kunye nokumelana neentanda kwengubo.
5. Ukuphucula ukumelana kwamanzi kweengubo
Ukumelana namanzi kweengubo ezisekelwe kwisamente kubalulekile ekwakheni iingcango zangaphandle, ii-basement, kunye nezinye iindawo ezichatshazelwe kukufuma okanye amanzi. Iimpawu zokugcina amanzi ze-HEMC zinokucothisa ngempumelelo ukulahleka kwamanzi kwiingubo ezisekelwe kwisamente, ngaloo ndlela ziphucula ukumelana namanzi kwengubo. Ukongeza, i-HEMC inokusebenzisana nezithako ezikwisamente ukuphucula amandla okulwa nokungena kwengubo, ngaloo ndlela iphucula ukusebenza kokungena kwamanzi kwengubo.
6. Ukuphucula i-rheology yeengubo
Ukusetyenziswa kwe-HEMC kwiingubo ezisekwe kwisamente kunokuphucula i-rheology yengubo, kuyenze ibe nokuthamba okungcono kunye neempawu zokulinganisa. Emva kokongeza i-HEMC kwiingubo ezisekwe kwisamente, ukuthamba kwengubo ngexesha lenkqubo yokugquma kuyaphuculwa, kwaye umphezulu wengubo unokwenza ingubo egudileyo nefanayo, kuthintelwe iziphene zengubo ezibangelwa kukuxinana okugqithisileyo okanye okungalinganiyo kwengubo.
7. Ukusebenza kokusingqongileyo
Njenge-polysaccharide yendalo,I-HEMC inokonakala kakuhle kwaye ngenxa yoko isebenza kakuhle kwindalo esingqongileyo. Ingathatha indawo yezinye izongezo zeekhemikhali ezenziweyo kwaye inciphise izinto eziyingozi kwiingubo, ngaloo ndlela iphucula ukusebenza kwindalo esingqongileyo kweengubo ezisekelwe kwisamente. Kwiingubo zanamhlanje zokwakha, ukhuseleko lwendalo luye lwaba yinto ephambili kwimarike nakwimimiselo, ngoko ke ukusetyenziswa kwe-HEMC kudlala indima entle ekuphuculeni ukhuseleko lwendalo lwengubo.
8. Phucula ukuqina kwepeyinti
Ukongezwa kwe-HEMC kunokuphucula ukumelana nokuguguleka, ukumelana nemozulu kunye nokumelana ne-UV kwezambatho ezisekelwe kwisamente. Kunganciphisa iingxaki ezifana nokunyamalala nokuqhekeka kwezambatho ezisekelwe kwisamente ezibangelwa zizinto zangaphandle zokusingqongileyo ezifana nokukhanya kwelanga kunye nokukhukuliseka kwemvula, kwaye kuphucule ukuqina kwengubo. Le nzuzo ifanelekile ngokukodwa ekwakheni iingubo zodonga zangaphandle ezivezwa kwimeko-bume yangaphandle ixesha elide kwaye zinokwandisa ubomi benkonzo yengubo.
9. Ukuphucula iipropati zokulwa neentsholongwane zepeyinti ezisekelwe kwisamente
Njengoko iimfuno zempilo nokhuseleko lwezixhobo zokwakha ziqhubeka zisanda, iimpawu zokulwa namagciwane kwiingubo ziya kuba ngumgaqo obalulekileyo. I-HEMC ngokwayo ineempawu ezithile zokulwa namagciwane kwaye inokuthintela ngempumelelo ukukhula kwesikhunta kunye neebhaktheriya kumphezulu wengubo. Kwindawo enomswakama ophezulu, ukongezwa kwe-HEMC kunokunceda ingubo imelane nokubola kwesikhunta kunye neefungi kwaye kuphucule ucoceko kunye nokuqina kwengubo.
10. Ukuphucula ukhuseleko lokwakhiwa kweengubo ezisekelwe kwisamente
Njengekhemikhali engenabungozi nengacaphukisiyo, i-HEMC ikhuselekile kakhulu. Ngexesha lenkqubo yokwakha,I-HEMCAyinabungozi kangako emzimbeni womntu kwaye inciphisa impembelelo kwimpilo yabasebenzi bokwakha. Ukongeza, i-HEMC inokunciphisa ngempumelelo uthuli oluveliswa ngexesha lenkqubo yokwakha, ngaloo ndlela iphucula umgangatho womoya kwindawo yokwakha.
Ukusetyenziswa kwei-hydroxyethyl methylcelluloseKwizinto zokugquma ezisekwe kwisamente zinezibonelelo ezininzi. Ayinakuphucula kuphela ukusebenza kolwakhiwo lwento yokugquma, yandise ixesha lokuvula, kwaye iphucule ukunamathela, kodwa ikwaphucula ukumelana nokuqhekeka, ukumelana namanzi, i-rheology kunye nokuqina kwento yokugquma. Ukongeza, i-HEMC, njengesongezelelo esinobuhlobo nokusingqongileyo nesingenatyhefu, ayiphuculi kuphela ukusebenza kwento yokugquma, kodwa ikwanceda ekunciphiseni umthwalo wokusingqongileyo. Ke ngoko, i-HEMC isetyenziswa kakhulu kwiinto zokugquma ezisekwe kwisamente zanamhlanje kwaye ibe yinxalenye ebalulekileyo ekuphuculeni umgangatho wento yokugquma kunye nokusebenza kakuhle kolwakhiwo.
